Costco might be known for bulk snacks and giant muffins, but it turns out some Michelin-star chefs are cruising those aisles too. They’re not loading up on just anything though—they’ve got opinions, and they don’t hold back. From pantry staples they swear by to items they’d rather leave behind, it’s a peek into shopping carts you never expected. Turns out even award-winning chefs appreciate a good deal, but only if the quality checks out. If you’ve ever wondered what Michelin-star chefs buy at Costco without blowing cash on duds, this list spills it all.
Cauliflower Pizzas

Tyler Malek says these pizzas save time and fill you up without wasting. The cauliflower base holds toppings firmly and bakes crisp, even without fresh dough. They work well for quick lunches or light dinners. A smart grab for anyone wanting flavor without starting from scratch.
Frozen Sea Bass

Ron Hsu highlights how filets come clean and ready to cook—no prep required. They’re big and mild, so you can season hard or go subtle. Perfect when you want restaurant-level seafood at home. And the price beats most fish counters.
Mama Lil’s Peppers

Tyler Malek keeps these on hand to punch up anything from eggs to pizza. They add big flavor and color without derailing a dish. Plus, they last forever in the fridge. A tiny jar that goes huge in recipes.
Beecher’s Mac ‘n Cheese

Malek says this mac pairs perfectly with those peppers—and he’s not wrong. The cheese sauce comes creamy with just the right bite. It warms up fast and works as a side or main. A solid wingman in the frozen aisle.
Frozen Broccoli

Ron Hsu praises the bit of crunch that stays after cooking. It doesn’t go limp or soggy, which means better mouthfeel. Great for quick sides or tossed into stir-fries. A no-brainer for chefs who hate mush.
Kirkland Shrimp Cocktail Platter

Peter Som loves the versatility—cold straight or stir-fried with a kick of sambal and lime. It’s a giant shrimp tray that can fuel shrimp tacos or shrimp fried rice. Good size for sharing or scaling up. A clever buy for busy chef kitchens.
Kirkland Pecan Halves

Kirkland Organic Extra Virgin Olive Oil

Chef Castro picks this EVOO for its consistent taste and price point—2 L for under $23 is tough to beat. It behaves like a top-shelf oil in dressings or finishing dishes. A reliable bottle that’s kitchen-ready every time.
Kirkland Wild Caught Chilean Sea Bass

Karadsheh points out how versatile and easy this fish is to cook. It holds its shape, has mild flavor, and takes seasoning well. You can pound out a nice dinner in under thirty minutes. A chef’s shortcut to restaurant-grade seafood.
Kirkland Organic Pasture‑Raised Eggs

Pache stocks up on these for baking and breakfasts, thanks to the affordable value even in large packs. They look and taste like farm-fresh eggs in everything from omelets to cakes. Egg-heavy kitchens will thank you.
Bonne Maman Four‑Fruits

A slather of these preserves on fresh bread brings restaurant-level quality fast. It tastes fruity yet balanced, like a class trip to Provence in one jar. Every pastry chef’s secret for effortless flair.
Parthenon Pitted Kalamata Olives
