We shop at Costco nearly every week. While our cart often includes treats, we prioritize healthier choices too. For us, clean eating isn’t about rigid rules or eliminating entire food groups. It’s about choosing foods with short ingredient lists, minimal processing, and nutrient-dense ingredients like whole grains, lean proteins, and fresh produce.
Costco makes this approach easier and more affordable—you can stock up on wholesome staples in bulk and get good value without compromising quality.
Below are the clean-eating items we regularly buy at Costco and recommend for stocking a nutritious pantry and freezer.
Grains & Pantry Staples
1. Brown Rice & Millet Noodles
Millet or brown rice noodles are a cleaner alternative to instant ramen and many highly processed noodles. With a short ingredient list and a pleasant texture when prepared according to package directions, they work well in stir-fries, soups, and cold noodle salads.
2. Organic Brown Rice
A 12.5-pound bag might seem like a lot, but it’s great for households that eat rice frequently. The organic, parboiled variety cooks faster than traditional brown rice, making it convenient for weeknight meals.
3. Organic Quinoa
Kirkland Signature organic quinoa is an excellent value. Quinoa is versatile—use it as a side, add it to salads and soups, or incorporate it into breakfast dishes like muffins or bowls for extra protein and fiber.
4. Dried Lentils
Lentils are simple, budget-friendly, and protein-packed. They cook relatively quickly and are perfect for soups, stews, curries, and hearty salads.
5. Organic Canned Beans
Costco’s bulk cans of black beans, red beans, and chickpeas are convenient and minimally processed. Just rinse and add to salads, tacos, bowls, or soups for a quick protein and fiber boost.
Dairy & Dairy Alternatives
6. Kirkland Signature Greek Yogurt
This is a frequent repeat buy. It’s thick, creamy, and tangy—ideal for smoothies, parfaits, or as a sour cream substitute. The large tub offers strong value compared with typical grocery-store sizes.
7. Silk Unsweetened Almond Milk
Choose unsweetened varieties for cleaner labels. Costco often sells multi-packs of almond milk at a lower price than single cartons, making it an economical choice for oatmeal, smoothies, and baking.
Proteins & Seafood
8. Chicken Thighs & Breasts
Costco’s chicken packs are typically pre-portioned for easy defrosting. The price per pound is competitive, and chicken is a reliable source of lean protein for weeknight dinners.
9. Ground Chicken & Ground Turkey
Ground poultry is a cleaner swap for some ground-beef recipes. Use it in tacos, stir-fries, meatballs, and sauces when you want a leaner profile.
10. Ground Beef & Steak
Look for lean ground beef if you’re focused on clean eating. Steaks are also a solid option when buying for grilling or special meals.
11. Kirkland Signature Wild Pacific Cod
This wild-caught cod is mild and flaky, cooks quickly, and makes an easy weeknight entrée with minimal prep.
12. Wild Gulf Shrimp
Peeled and deveined shrimp are a freezer staple. They speed up dinner prep and work well in pastas, stir-fries, salads, and tacos.
Nuts, Seeds & Nut Butters
13. Nuttzo Organic 7 Nut & Seed Butter
A mix of nuts and seeds—almonds, cashews, chia, flax, and more—this butter is nutrient-dense and flavorful. It’s tasty on toast, stirred into oatmeal, or enjoyed by the spoonful.
14. Kirkland Signature Organic Almond Butter
This almond butter usually contains just 100% almonds with no added sugar or oils, making it a straightforward, clean option at a good price.
15. Kirkland Signature Unsalted Mixed Nuts
A mix of cashews, almonds, hazelnuts, and walnuts without added salt—perfect for snacking or adding to oatmeal and salads for extra protein and healthy fats.
Drinks & Extras
16. Vintage Seltzer Water
Plain sparkling water with no sweeteners or additives is a great way to add variety without turning to soda or juice.
17. Frozen Veggies & Fruit (Bonus!)
Costco’s frozen produce selection changes, but organic frozen broccoli and blueberries are often available and extremely useful for smoothies, sides, and meal prep.
