Check out this Costco Mediterranean Diet shopping list before you head to the warehouse.
The Mediterranean diet—consistently rated among the best by experts—is less a short-term fad and more a sustainable lifestyle focused on whole foods, balanced meals, and enjoying food with family and friends. Rooted in the traditional eating patterns of countries bordering the Mediterranean Sea, it emphasizes vegetables, fruits, whole grains, legumes, healthy fats like olive oil, lean proteins, and moderate dairy.
Although the image of leisurely seaside meals may feel distant from daily life, you can incorporate many Mediterranean staples by making smart choices at Costco. The warehouse carries a variety of products that make it easier to follow this way of eating without sacrificing convenience or flavor.

Olive Oil
Olive oil is the cornerstone of Mediterranean cooking—ideal for salad dressings, roasting, and light sautéing. Despite market fluctuations, Costco’s Kirkland Signature Organic Olive Oil is often a reliable, cost-effective choice.
Kalamata Olives
Kalamata olives bring a bold, salty flavor to salads, pastas, and snacks. They keep well when refrigerated, so a larger container can last if stored properly.
Castelvetrano Olives
Milder and less salty than Kalamatas, Castelvetrano olives are bright and buttery—great for salads, cheese boards, or tossed into pasta.
Feta Cheese
Unprocessed cheeses like feta add tang and creaminess to many dishes. Use crumbled feta on salads, omelets, or roasted vegetables for extra flavor.
Taylor Farms Mediterranean Crunch Salad Kit
This kit blends multiple lettuces and vegetables with crunchy additions and feta. Add grilled protein like chicken or chickpeas to make a quick, satisfying Mediterranean-style meal.
Shrimp
Shrimp is a lean, versatile protein perfect for salads, skewers, or pasta. Wild-caught options are convenient to keep on hand for quick dinners.
Chicken Tenderloins
Lean chicken breast or tenderloins are a Mediterranean mainstay. Vacuum-sealed packages help with portioning and reduce freezer burn, making meal prep easier.
Ground Turkey
Red meat is limited in Mediterranean eating, so ground turkey is a great substitute. If portions come in larger packs, divide and freeze in recipe-sized portions to reduce waste.
Chickpeas
Chickpeas boost protein and fiber in salads or make a crunchy snack when roasted and seasoned. They’re a versatile pantry staple for Mediterranean-style meals.
Quinoa
Quinoa is a nutrient-dense whole grain that adds texture and protein to salads, bowls, and side dishes. Leftovers can be repurposed into easy breakfasts or snacks.
Greek Yogurt
High-protein Greek yogurt works for breakfast parfaits, creamy dressings, or as a base for sauces. Plain varieties are especially versatile for savory and sweet uses.
Tzatziki
Tzatziki is a refreshing yogurt-based dip that pairs well with vegetables, grilled meats, and falafel—adding brightness to many Mediterranean dishes.
Chicken Thighs
Chicken thighs roast and grill well without drying out, making them ideal for sheet-pan dinners with vegetables—an easy, family-friendly Mediterranean option.
Brown Rice
Whole grains like brown rice add fiber and substance to meals and are a dependable base for bowls and grain salads.
Cauliflower Rice
Cauliflower rice is a quick way to boost vegetable intake and can substitute for grains in many recipes. Buy it when available for added convenience.
Canned Tuna
Tinned fish is rich in omega-3s and is handy for quick lunches and salads. Costco carries several tuna options to suit different tastes and recipes.
Falafel
Pre-cooked falafel provides a convenient vegetarian protein that works well as an appetizer, in pita sandwiches, or over mixed greens.
Gyro Slices
Ready-to-heat gyro slices made from beef and lamb are an easy way to assemble pitas, grain bowls, or salads for quick Mediterranean-style meals.
Chicken Patties
Preformed chicken patties are useful for meal prep—add them to salads or serve on whole-grain buns as a lighter alternative to burgers.
Hummus
Hummus is a classic Mediterranean dip and bowl topper. Large containers are great for home use, while smaller tubs suit lunches and snacks.
Chia Seeds
Chia seeds add fiber and omega-3s and are excellent for overnight puddings, smoothies, or sprinkled on yogurt and salads for extra texture and nutrition.
Frozen Salmon
Keeping frozen salmon on hand makes it easy to eat fish several times a week, as recommended in Mediterranean eating patterns. Salmon is versatile, nutritious, and cooks quickly from frozen or thawed.
