18 Brand-New Costco Finds You’ve Never Spotted! (May 2026)

May 25, 2026

From guilt-free popcorn to zesty steak, Costco’s May 2026 lineup is a flavor-packed adventure. We’ve tested the hottest new snacks, frozen treats, and pantry essentials you can’t afford to miss!

1. Kirkland Signature Coconut Oil Popcorn

I ripped open one of these convenient pre-popped snack bags expecting the usual bland vending-machine style corn, but I was met with a beautifully clean, aromatic snack that completely elevates standard movie night munchies.

Price: $11.99 (Budget-friendly multi-pack warehouse value)
Taste Test: Incredibly clean and pure. The sea salt is perfectly distributed without being overwhelming, and the organic coconut oil leaves a subtle, pleasantly sweet tropical undertone without any heavy, greasy artificial butter flavor.
Texture Summary: Fluffy, light, and wonderfully crisp. Very few stubborn kernels or hulls to worry about.
Make It Better: Shake up the bag with a heavy sprinkle of nutritional yeast or a dash of tajín seasoning for an instant savory kick.
Perfect Pairings: A cold can of prebiotic berry soda and a cozy couch setup for a late-night movie marathon.
Final Verdict: BUY (The ultimate guilt-free, low-calorie crunch.)

2. Siete Sourdough Tortillas

As a gluten-free bread critic, I was practically sprinting to the stove to heat these up. Siete is famous for its grain-free alternatives, but their brand-new sourdough-style release has left the internet—and my own tastebuds—in a bit of a spin.

Price: $10.99 ($9.00 at warehouse clubs for a large pack, but historically premium priced)
Taste Test: To be brutally honest, if you are looking for that classic, sharp, fermented sourdough tang, you won’t find it here. The community is right: it tastes almost identical to a standard corn tortilla.
Texture Summary: Disappointingly dry and dense straight out of the pack. Like most gluten-free wraps, it will crack and spill your fillings if you try to roll it cold.
Make It Better: Absolute mandatory hack: toast it directly over an open flame or in a hot dry skillet for 2 minutes per side until it puffs and browns. This softens it completely.
Perfect Pairings: Perfect for loaded quesadillas or sturdy enchiladas where the cheese and sauce can lock in moisture.
Final Verdict: SKIP (Stick to Siete’s superior almond flour tortillas unless you just want a giant, expensive corn tortilla substitute).

3. True Story Grass-Fed Hot Dogs

I am on a mission to clean up my summer grill sessions, so I threw these organic, grass-fed links onto a screaming hot cast-iron skillet. I wanted to see if a hot dog made with absolute structural integrity could compete with nostalgic childhood favorites.

Price: $14.74 6-count pack
Taste Test: Phenomenal, pure beef flavor. It is lightly smoked and delicately seasoned with garlic and onion powder, offering a rich, savory depth without that intense, lingering salty chemical aftertaste of cheap franks.
Texture Summary: Plump and incredibly juicy on the inside, though it features a completely skinless finish—meaning you get a tender bite rather than a loud, snappy casing pop.
Make It Better: Butterfly the hot dog down the center before grilling to maximize those gorgeous, crispy caramelized edges.
Perfect Pairings: Nestled in a toasted brioche bun with lacto-fermented spicy brown mustard and a side of homemade sweet potato fries.
Final Verdict: BUY (The cleanest, most delicious hot dog on the market right now.)

4. Jesse Ben’s Frozen Fries

I loaded these gourmet frozen cut spuds into a preheated air fryer to test the holy grail of freezer aisle sides. A great frozen fry needs to bridge the gap between restaurant-quality indulgence and easy weeknight convenience.

Price: $11.99 (Affordable, high-volume freezer essential)
Taste Test: Exceptionally potato-forward with just a whisper of sea salt. They lack that weird, artificial grease flavor that coats your mouth when eating fast-food alternatives.
Texture Summary: A textbook perfect contrast. The exterior develops a shatteringly crisp skin in the air fryer while the interior remains pillowy, fluffy, and steamed to perfection like a fresh baked potato.
Make It Better: Toss them in a bowl with a drizzle of truffle oil, freshly grated parmesan, and finely chopped parsley the second they come out of the heat.
Perfect Pairings: A juicy smash burger, or dipped into an ultra-savory garlic aioli.
Final Verdict: BUY (Your freezer should never be without a bag.)

5. Ithaca Olive Oil Hummus

I cracked open this much-hyped collaboration tub with high hopes because I absolutely adore Graza olive oil. Digging my chip into the center, I realized immediately why this specific launch has sparked an absolute civil war on food forums.

Price: $8.50 (A premium price tag for an upgraded, co-branded deli tub)
Taste Test: Lip-puckeringly intense. Ithaca is famous for its heavy-handed use of raw lemon juice and vinegar. If you love a sharp, ultra-bright, citrusy acid punch, you’ll be obsessed. If you prefer earthy, nutty tahini, you’ll think it tastes too sour.
Texture Summary: Silky smooth and utterly spreadable, though heavily pooled with rich, liquid olive oil that can feel a bit gritty or mushy to classic purists.
Make It Better: The deep, angular plastic tub corners make scooping a nightmare; dump it into a shallow bowl and stir in a spoonful of chili crisp or za’atar to balance the acid.
Perfect Pairings: Warm, freshly toasted pita bread and a crunchy, Mediterranean chopped cucumber salad.
Final Verdict: BUY (But only if you are a certified lemon-and-acid fanatic!)

6. Lemon Pasta in a Box

I boiled up this premium, all-in-one shelf-stable meal kit on a hectic Monday night. I’m always skeptical of dehydrated sauce packets, but I was looking for a bright, effortless shortcut to an elegant Italian dinner.

Price: $6.99 (Budget-friendly shelf-stable convenience)
Taste Test: Surprisingly vibrant! The lemon flavor relies on real citrus zest notes rather than chemical acidity, providing a sunny, cheerful brightness that cuts beautifully through the starchy pasta water base.
Texture Summary: The noodles hold up beautifully to an al dente bite, coating themselves in a silky, light sauce that isn’t clumpy or gluey.
Make It Better: Stir in a splash of heavy cream, a handful of fresh baby spinach, and some cracked black pepper during the final minute of tossing.
Perfect Pairings: Pan-seared shrimp or grilled chicken breast, accompanied by a chilled glass of Pinot Grigio.
Final Verdict: BUY (An elite pantry staple for lazy gourmet nights.)

7. Malk Almond Milk

I poured this minimalist plant milk into my morning coffee to see if a clean label translates to a satisfying morning brew. Malk prides itself on using absolutely zero gums, thickeners, or oils—just organic almonds, filtered water, and sea salt.

Price: $14.74 (Premium pricing reflecting the ultra-clean, filler-free ingredient list)
Taste Test: Incredibly clean, pure, and nutty. It tastes exactly like real almonds soaked in water, completely free from the synthetic vanilla or chalky sweetener flavors found in mass-market brands.
Texture Summary: Very thin and watery compared to traditional milk. Because it completely lacks chemical emulsifiers, it will naturally separate in your fridge and requires a vigorous shake before every use.
Make It Better: Warm it up gently before pouring it into hot coffee or tea to prevent the temperature shock from causing the natural almond solids to curdle.
Perfect Pairings: Poured over a bowl of organic steel-cut oatmeal, or blended into a vibrant green spinach-and-berry smoothie.
Final Verdict: BUY (An absolute triumph for health purists; skip it if you want a thick, heavy creamer).

8. Ninja Blend Boss Blender

I loaded this amped-up, heavy-duty personal blender with frozen fruit, tough kale stems, and solid ice cubes to test its raw pulverizing power. I wanted to see if its trendy, cup-holder-friendly silhouette could genuinely compete with the muscle of a full-sized professional unit.

Price: ($129.99 MSRP for a premium, high-power personal tumbler blender)
Performance Test: Absolute destruction of tough fibers. Running the Auto-iQ smoothie setting completely eliminated annoying kale threads and berry seeds, yielding a perfectly uniform liquid without needing to stop and stir.
Build & Design Summary: A heavy, rock-solid 1100-watt motor base equipped with incredibly strong suction feet so it doesn’t dance across your counter. The 26 oz travel tumbler feels thick, durable, and features a brilliant leakproof flip-cap with a flexible, self-popping straw.
Make It Better: Keep a close eye on the front button of the travel lid—while the cap locks tightly, hitting that button accidentally in a packed bag can flip it open. When packing it on a hike or commute, face the button away from loose items.
Perfect Pairings: Pairs flawlessly with your standard car cup holder, morning gym bags, and high-intensity meal prep routines.
Final Verdict: BUY (An absolute personal-sized workhorse that packs full-size Vitamix power into a portable footprint.)

9. Churn Grassfed Butter

I unpucked this premium, small-batch compound butter and let it soften on my counter. Churn uses pasture-raised, grass-fed cream to create flavored butters designed to instantly elevate home cooking, and the aroma alone is intoxicating.

10. Blueland Toilet Bowl Cleaner

I dropped one of these plastic-free, effervescent cleaning tablets into the water to step away from traditional, harsh chemical bottles. I watched it vigorously fizz to life, eager to see if a sustainable, eco-conscious tablet could handle a chore that usually requires intense chemical intervention.

Price: $49.99 (Highly affordable, budget-friendly refill system at around $0.83 per tablet)
Performance Test: Surprisingly effective at standard grime. It fills the room with a remarkably fresh, natural scent (like Peppermint Eucalyptus or Lemon Cedar) rather than triggering a coughing fit from heavy chlorine or synthetic bleach fumes.
Build & Design Summary: A beautiful, zero-plastic setup. The starter kit comes with a chic, highly recyclable steel “Forever Tin” to store your supplies, while the replacement tablets ship in fully compostable paper wrappers.
Make It Better: Dissolving times vary based on water temperature, taking anywhere from 2 to 5 minutes. The ultimate hack: drop the tablet in, leave the toilet lid wide open to let the spa-like aroma fill your bathroom, and wait a full 10 minutes before brushing so the enzymes can maximize their stain-lifting power.
Perfect Pairings: Pairs beautifully with a sturdy toilet brush, a tin of Blueland bathroom spray for the porcelain exterior, and a completely zero-plastic cleaning aesthetic.
Final Verdict: BUY (It makes a boring chore satisfying, smells great, and keeps heavy plastic jugs completely out of landfills.)

11. Kirkland Signature Ultra-Filtered Milk

I poured a cold glass expecting a standard grocery staple, but this Costco newcomer immediately turned my kitchen into a high-protein, dairy-fueled wonderland.

Price: $13.61 (Unbeatable warehouse value for a 3-pack of half-gallons)
Taste Test: Absolute velvety perfection. It has a deeply rich flavor that tastes far more like a premium cream than standard milk, completely lacking that watery finish. The buzz is real: it is a dead ringer for Fairlife.
Texture Summary: Ultra-creamy and remarkably full-bodied due to the specialized filtration process that concentrates the proteins (13g per serving) while removing the lactose.
Make It Better: Use it as the base for a high-protein iced matcha latte or blend it with frozen bananas for a naturally sweet milkshake texture without added sugars.
Perfect Pairings: A tall cold glass is begging to be paired with warm, freshly baked cookies, or used to step up your morning bowl of artisan granola.
Final Verdict: BUY (Grab two packs before the fitness crowd clears the shelves!)

12. Kirkland Signature Blueberry Sourdough Bread

Stepping up to the bakery counter, the sweet scent of fruit and fermented dough hit me instantly. I snagged this heavy, two-pound loaf and sliced into it immediately to see if the internet hype held up—and they didn’t skimp on the fruit.

Price: ($10.20 for a massive, heavy 2-lb bakery loaf)
Taste Test: A brilliant, complex contrast of flavors. You get the distinct, tangy bite of traditional sourdough yeast perfectly balanced by the bright, bursting sweetness of whole real blueberries studded throughout the crumb.
Texture Summary: A beautiful artisan structure boasting a rustic, slightly chewy crust with a soft, pillowy, and moist interior.
Make It Better: Slice it thick, dip it in a rich vanilla-cinnamon egg wash, and turn it into the ultimate gourmet weekend French toast.
Perfect Pairings: Slathered in whipped mascarpone cheese, a smear of salted Kerrygold butter, or alongside a hot cup of dark roast espresso.
Final Verdict: BUY (An absolute masterpiece of a breakfast bread!)

13. Jeni’s Key Lime Pie Ice Cream Sandwiches

Having spotted these exclusive 8-packs causing mass hysteria in freezer aisles, I had high expectations. Unwrapping one of these gorgeous treats, I went in for a massive bite to see if the premium brand pedigree translates to a handheld format.

Price: ($14.49 for an 8-pack, which is a massive steal for the premium Jeni’s brand)
Taste Test: Exceptionally tart! Unlike most “key lime” desserts that choke you with artificial sweetness, this packs an authentic, face-puckering citrus punch courtesy of real lime oil and cultured buttermilk.
Texture Summary: The ice cream is lush and velvety, though lighter and slightly airy. The graham cracker cookies are completely soft and yielding rather than crunchy—perfectly mimicking a soggy, delicious pie crust.
Make It Better: Let it sit on the counter for exactly two minutes before eating so the soft graham cookies melt harmoniously into the lime core.
Perfect Pairings: Best enjoyed poolside on a humid afternoon, or paired with a crisp, ice-cold Sauvignon Blanc.
Final Verdict: BUY (A certified must-have for true lime fanatics!)

14. Costco Bakery Sweet & Salty Cookies

Walking past the bakery, I watched these 24-packs fly into carts like wildfire. I cracked open the plastic clamshell and grabbed a cookie that felt heavy, dense, and promised an incredible multi-textured experience.

Price: ($12.47 for a generous 24-count pack)
Taste Test: A decadent rush of brown butter dough and rich chocolate chips. The caramel pieces add an ultra-sweet chew, though I found the initial bite leans heavily into the “sweet” territory, with the savory, salty pretzel crunch hitting beautifully on the finish.
Texture Summary: Marvelously multi-textured. It features slightly crisp, golden edges, an incredibly soft and gooey center, and a distinct crunch from the embedded pretzel bits.
Make It Better: Pop a cookie into the microwave for exactly 8–10 seconds to melt the caramel bits and chocolate chips into a warm, gooey mess.
Perfect Pairings: A strong, unsweetened cold brew coffee to cut through the intense sweetness, or a scoop of plain vanilla bean ice cream.
Final Verdict: BUY (Perfect for parties, family gatherings, or late-night cravings.)

15. Olipop Spring Variety Pack

I cracked open a gorgeous, pastel-colored can of the “Raspberry Sherbet” flavor from this limited-edition 15-pack. Functional prebiotic sodas are totally dominating the drink market, and I wanted to see if these seasonal profiles taste like a true treat.

Price: $18.99 (Great bundle value for a premium 15-can club pack)
Taste Test: Incredibly nostalgic and fun. Flavors like Strawberry Vanilla and Shirley Temple balance crisp carbonation with a brilliant fruit-forward sweetness that completely masks the plant-based fibers and stevia notes.
Texture Summary: Light, refreshing, and deeply bubbly with a smooth, clean finish that doesn’t leave a sticky, sugary film on your teeth.
Make It Better: Serve it in a chilled wine glass over crushed ice with a fresh lime wheel or a handful of muddled fresh berries.
Perfect Pairings: A fantastic midday pick-me-up paired with a light turkey wrap, or served as a guilt-free non-alcoholic beverage option at weekend spring barbecues.
Final Verdict: BUY (The absolute best way to stock up on healthy bubbles for the season.)

16. Mango on a Stick

I pulled one of these beautifully scored, bright orange frozen mango spears straight from the box. Frozen fruit treats are having a massive summer moment as a clean-label alternative to sugary ice pops, and this one looks like pure vacation.

Price: $14.18 (Inexpensive and highly accessible frozen snack)
Taste Test: Pure, unadulterated sunshine. It tastes exactly like a perfectly ripe, sun-drenched sweet Mexican mango at peak season, carrying a subtle floral undertone without any added syrups or preservatives.
Texture Summary: Dense, creamy, and frozen firm. As it thaws slightly, it adopts a velvety, smooth texture that mimics a natural sorbet.
Make It Better: The ultimate street-style hack: dredge the frozen mango stick in a heavy dust of Tajín seasoning and a fresh squeeze of lime juice for an incredible sweet, salty, and spicy kick.
Perfect Pairings: A refreshing backyard snack alongside an ice-cold sparkling water, or enjoyed right after a spicy taco night dinner.
Final Verdict: BUY (A refreshing, single-ingredient summer essential for kids and adults alike.)

17. Archer Grass-Fed Beef Jerky

I pulled a tender strip of this brand-new artisan flavor addition out of the bag. Premium, grass-fed snacks are sweeping the convenience aisles, and I wanted to see if Archer could deliver a gourmet chew without relying on heavy artificial preservatives.

Price: $20.31 (Standard premium tier pricing for grass-fed meat snacks)
Taste Test: Wonderfully deep and savory. The grass-fed beef imparts a rich, clean meat flavor that pairs beautifully with a subtle marinade of smoky soy and cracked black pepper, completely avoiding that artificial, chemical-heavy sweetness of gas station jerky.
Texture Summary: Remarkably tender and easy to chew. It strikes the perfect balance—dry enough to keep its shelf life but moist enough that you aren’t tearing it apart with your teeth.
Make It Better: Warm up the strips for just 5 seconds in the microwave to release the natural beef oils and spices for a fresh-carved smokehouse experience.
Perfect Pairings: Pack it alongside a handful of raw almonds and sharp white cheddar cheese blocks for an elite, high-protein hiking fuel.
Final Verdict: BUY (An exceptional, travel-friendly snack for fitness fans and road-trippers.)

18. Kirkland Signature Lime Cilantro Flank Steak

I sliced into this pre-marinated, ready-to-grill flank steak fresh off a blazing hot iron skillet. Costco’s prepared meat section is the ultimate weekday shortcut, and this seasonal May rollout promises carne asada quality without any prep.

Price: $17.01/lb (Excellent price-per-pound value for a premium pre-marinated cut)
Taste Test: Superbly bright and zesty! The lime juice marinade works its way deep into the meat, offering a sharp citrus pop that cuts beautifully through the rich beef fat, while the fresh cilantro provides an authentic, aromatic finish.
Texture Summary: Incredibly juicy and melt-in-your-mouth tender, provided you cook it to medium-rare and slice it thinly against the grain.
Make It Better: Sear it on an incredibly hot outdoor grill or cast-iron pan to develop a deeply charred, smoky crust that locks in the citrus juices.
Perfect Pairings: Thinly sliced inside charred corn tortillas, topped with diced white onions, fresh salsa verde, and a cold Mexican lager.
Final Verdict: BUY (An absolute no-brainer for effortless, restaurant-quality taco nights.)
