We’re big fans of Costco meal prep here at Warehouse Wanderer, and the warehouse aisles are packed with smart buys that make planning a breeze. After years of testing and tasting, these are the items we always come back to—because they’re not only cheaper than what you’d find at most grocery stores, but they save serious time in the kitchen.
Whether you’re stocking up on cooked proteins or pantry essentials, these Costco finds earn their cart space every time.
Proteins
Rotisserie Chicken
The classic Costco rotisserie chicken is a legend for a reason. It’s cheaper than buying raw and already cooked to perfection. I shred it up for salads, wraps, chicken salad, pasta—you name it.
Sliced Grass-Fed Sirloin
This fully cooked sirloin comes in two ready-to-go portions, and it’s a lifesaver. Heat it in a pan or eat it cold—it’s perfect for quick tacos, sandwiches, or salads.
Salmon (Frozen Atlantic Farm Raised)
I love the mellow flavor of Costco’s farm-raised frozen salmon—it’s super versatile and comes in individually portioned servings. We usually cook it in Bachan’s Japanese BBQ sauce, then throw it in grain bowls or serve it with rice and veggies.
Bare Chicken Nuggets
These taste like fancy Chick-fil-A nuggets but without the drive-thru. They’re juicy, not spicy, and totally kid-approved. I love tossing a few on top of a Cobb salad or into a wrap.
Shrimp (Kirkland Signature Gulf Shrimp)
These frozen shrimp are a perfect size, taste fresh, and are super affordable. Skip the pre-cooked ones—they’re rubbery and sad. Raw shrimp only takes a few minutes to cook and are way better.
Eggs
Egg prices have calmed down, and Costco’s big packs are great for meal prep. I love keeping a batch of hard-boiled eggs in the fridge—they’re perfect for salads and grain bowls and stay fresh for up to a week if you leave the shells on.
Pulled Pork
Costco recently updated its pulled pork, and it’s so much better now. It’s fully cooked, reheats in minutes, and is amazing on its own, in tacos, or on top of salads and rice bowls.
Vegetables
Salad Kits
Costco’s salad kits are total game changers. They come with everything—greens, toppings, dressing, even crunchy bits—and they actually taste good. I toss in some rotisserie chicken or chickpeas for an easy, filling lunch.
Bell Peppers
The full-size and mini bell peppers last forever in the fridge, so I never worry about waste. I use them in everything from stuffed peppers to fajitas to raw veggie snacks.
Sweet Potatoes
Sweet potatoes are a meal prep MVP. Roast them, mash them, or toss them in the air fryer—they’re filling, nutritious, and last a long time if stored in a cool, dark spot.
Frozen Broccoli
Costco’s big bag of frozen broccoli is a staple in my freezer. It’s great for stir-fries, omelets, and quick sides when I don’t want to chop anything.
Pantry Staple
Beans
Costco’s canned beans are budget-friendly and full of plant-based protein. When they go on sale, each can is under 75 cents—I stock up every time.
Chickpeas
Roasted chickpeas are my current obsession—they’re crunchy, savory, and perfect on salads or as a snack. Just rinse, toss with olive oil and smoked paprika, and roast until crispy.
Quinoa Pouches (Seeds of Change)
If you’re short on time, these 90-second quinoa and brown rice packets are a dream. They’re ready in a flash and go with everything.
Rice
Costco sells huge bags of rice for big families or serious rice fans. For everyone else, the precooked microwaveable rice packs are a convenient (and still affordable) shortcut.
Pasta (Barilla Variety Box)
This box comes with all the shapes—penne, elbows, bowties—so you’re ready for whatever pasta night looks like. It’s easy, kid-friendly, and meal-prep approved.
Tortillas
Wraps, quesadillas, burritos—you name it, tortillas make dinner fast and fun. Costco has both regular and low-carb options, and they last a while in the fridge.
Chia Seeds
These tiny seeds are a make-ahead breakfast hero. I use them for chia pudding or sprinkle them on yogurt and salads for a fiber boost.
Kodiak Cakes
I batch-make Kodiak protein pancakes and freeze them for busy mornings. Pop them in the toaster and you’ve got a filling, protein-packed breakfast ready in minutes.
Oats
Overnight oats are a meal prep classic, and Costco sells giant bags that’ll last for a long time. Add fruit, peanut butter, or protein powder for a customizable breakfast.
Meal planning doesn’t have to be a chore, especially when Costco has so many tasty, time-saving options to make it easier. Whether you’re cooking for a crowd or just trying to get dinner on the table during a busy week, these staples help take the guesswork (and the stress) out of mealtime.
