Costco Meal Prep Recipes
Costco and meal prep are a natural fit. Buying in bulk only makes sense if you cook in bulk, and these recipes are designed to do exactly that. Each one uses large-format Costco ingredients to produce four to six servings that reheat well throughout the week. These are the recipes that make a Costco membership truly pay for itself — not just in savings, but in the hours you get back during the week.

Costco Rotisserie Chicken Noodle Soup
Costco Rotisserie Chicken Noodle Soup
Homemade chicken noodle soup in under 40 minutes sounds too good to be true, but starting with a Costco rotisserie chicken makes it completely real. You skip the hours of simmering raw chicken by using already-cooked, already-seasoned meat and adding the carcass to the broth for extra depth. The result tastes like something that's been on the stove all day.
Costco Rotisserie Chicken Pasta Bake
Costco Rotisserie Chicken Pasta Bake
This pasta bake is the ultimate use of two Costco pantry staples: rotisserie chicken and Rao's marinara. Toss them together with rigatoni and a generous amount of mozzarella, bake until bubbly, and you have a dish that serves six and reheats beautifully for the rest of the week. It's a reliable crowd-pleaser that takes about 20 minutes of active time.
Baked Ziti with Rao's Marinara from Costco
Baked Ziti with Rao's Marinara from Costco
Baked ziti is one of those dishes that's almost impossible to mess up when you start with a great sauce. Rao's Homemade Marinara is the best jarred sauce you can buy, and Costco sells it at the best price. This recipe layers ziti, ricotta, mozzarella, and Rao's for a baked pasta that tastes like it came from a neighborhood Italian restaurant. It feeds eight, freezes beautifully, and tastes better reheated the next day.
Costco Italian Sausage and White Bean Soup
Costco Italian Sausage and White Bean Soup
Sausage and white bean soup is one of those recipes where the main ingredient does nearly all the work. Costco's Italian sausage is so well-seasoned that it transforms a simple broth into something rich and deeply flavored in 40 minutes. Add white beans, kale, and a Parmesan rind if you have one, and you have a soup that tastes like it's been cooking since morning.
Costco Frozen Salmon Teriyaki Bowls
Costco Frozen Salmon Teriyaki Bowls
Teriyaki salmon bowls are a weeknight powerhouse — high protein, genuinely satisfying, and ready in 30 minutes from a Costco freezer pack. The homemade teriyaki sauce takes 5 minutes to make and is dramatically better than anything from a bottle. The Costco salmon fillets are thick and meaty enough to hold up to the glaze and a hard sear without falling apart.
Sheet Pan Costco Chicken Thighs with Potatoes and Green Beans
Sheet Pan Costco Chicken Thighs with Potatoes and Green Beans
Bone-in, skin-on chicken thighs are the best cut for sheet pan dinners. They're nearly impossible to overcook, the skin gets crispy and golden in the oven, and the rendered fat drips down to baste the vegetables underneath. Costco sells them in large packs that are ideal for this recipe — make a full pan for dinner and pack the leftovers for lunch.
Costco Chicken Meal Prep Bowls
Costco Chicken Meal Prep Bowls
The best meal prep starts with Costco's rotisserie chicken. It's already cooked, already seasoned, and yields four cups of shredded meat that goes directly into containers. Pair with rice, a roasted vegetable, and a sauce that keeps well — and you have five complete meals that taste good through Friday. This is the recipe that makes a Costco membership pay for itself in real time.
Costco Overnight Oats Meal Prep (5 Jars)
Costco Overnight Oats Meal Prep (5 Jars)
Overnight oats are the meal prep gift that keeps giving. Costco's Kirkland rolled oats come in a large container that lasts months, and five jars of overnight oats take about 10 minutes to put together Sunday night. In the morning you have a nutritious, filling breakfast waiting in the fridge — no cooking, no cleanup, no thinking. Customize each jar with different toppings so the week doesn't feel repetitive.
2-Ingredient Costco Slow Cooker Salsa Chicken
2-Ingredient Costco Slow Cooker Salsa Chicken
Two-ingredient slow cooker salsa chicken is the kind of recipe that sounds too simple to be useful until you make it once and realize it solves dinner every week. Costco's large pack of chicken breasts and big jar of Kirkland salsa are all you need. Set it in the morning, shred it at dinner, and use it in tacos, burrito bowls, quesadillas, or nachos for the rest of the week.
Costco Rotisserie Chicken Tortilla Soup
Costco Rotisserie Chicken Tortilla Soup
Chicken tortilla soup is one of the best things you can make with a Costco rotisserie chicken. The broth gets its depth from fire-roasted tomatoes, chicken broth, and chili powder — and because the chicken is already cooked, the whole soup comes together in 30 minutes on a weeknight. Topped with crushed tortilla chips, shredded cheese, sour cream, and fresh cilantro, it's a complete, crowd-pleasing dinner.
Costco Rotisserie Chicken Salad
Costco Rotisserie Chicken Salad
Costco rotisserie chicken salad is the ultimate use-up recipe for leftover bird. Shred the chicken, fold it into a simple creamy dressing with celery and red onion, and you have a versatile filling that works in sandwiches, on crackers, in lettuce cups, or straight from the bowl. It keeps well for four days in the fridge — one Costco chicken makes enough for a week of lunches.
Costco Quinoa Salad
Costco Quinoa Salad
This Costco quinoa salad uses the Kirkland Signature organic quinoa as a hearty base, loaded with chickpeas, cucumber, cherry tomatoes, red onion, and a bright lemon-herb vinaigrette. It's the kind of salad that actually satisfies because the quinoa provides complete protein. Make a big batch on Sunday and it works for lunches all week — the texture holds up without getting soggy.
Italian Sausage Stuffed Peppers
Italian Sausage Stuffed Peppers
These stuffed peppers use Costco Italian sausage as the star filling — it's already seasoned with fennel and garlic, so all you do is brown it, mix with rice and Rao's marinara, stuff into bell peppers, and bake. The result is a complete meal in an edible bowl. Make a batch of six and you have dinner covered for most of the week.
Costco Broccoli Salad
Costco Broccoli Salad
This broccoli salad is one of those recipes that disappears at every gathering. Costco's large broccoli crowns are perfect — cut into bite-sized florets, tossed raw (or lightly blanched) with crispy bacon, dried cranberries, red onion, and a creamy, tangy dressing. Make it ahead and it only gets better. One large Costco broccoli crown makes enough for 8–10 servings.
Costco Kale Salad
Costco Kale Salad
Costco's large bags of pre-washed kale are one of the best deals in the produce section — and this salad makes full use of them. The key to great kale salad is massaging the leaves with dressing until they soften. This one uses a bright lemon-tahini dressing, toasted almonds, dried cranberries, and Parmigiano-Reggiano. It keeps well for 3 days, making it the ideal Sunday meal-prep salad.
Costco Ground Beef Chili
Costco Ground Beef Chili
This Costco ground beef chili is the kind of recipe you make once and eat four times. A Costco pack of ground beef, canned beans, fire-roasted tomatoes, and a well-built spice blend simmer into a rich, thick chili that tastes like it's been cooking all day. A small amount of cocoa powder deepens the color and adds complexity without making it sweet.
Costco Pulled Pork (Slow Cooker)
Costco Pulled Pork (Slow Cooker)
Pulled pork starts with Costco's bone-in pork shoulder (also sold as pork butt or Boston butt) — a large, fatty, collagen-rich cut that becomes silky and pull-apart tender after 8 hours in the slow cooker. The dry rub builds a crust, the low heat does the rest. One Costco pork shoulder feeds a crowd and freezes beautifully for weeks of easy meals.
Costco Slow Cooker Beef Stew
Costco Slow Cooker Beef Stew
Costco sells pre-cut beef stew meat that goes directly from the package into the slow cooker with minimal prep. The key to great beef stew is browning the meat first (10 minutes on the stovetop) and using a small amount of red wine or Worcestershire sauce for depth. After 8 hours on low, the beef is falling-apart tender and the broth is thick and intensely savory.
Costco Butternut Squash Soup
Costco Butternut Squash Soup
Butternut squash soup is one of the most satisfying soups you can make, and Costco's large butternut squash (often sold as a 2-pack) makes a generous pot. Roasting the squash first rather than simmering it directly in broth concentrates the sweetness and adds depth. The result is a silky, restaurant-quality soup that takes about an hour total and reheats beautifully all week.
Sheet Pan Pork Tenderloin
Sheet Pan Pork Tenderloin
Pork tenderloin is one of Costco's best meat values — lean, quick-cooking, and consistently tender. Costco sells them two to a pack at a price that makes each meal remarkably affordable. This sheet pan recipe roasts the tenderloin alongside potatoes and green beans in a single pan, finished with a honey-mustard glaze that caramelizes in the oven. Dinner in 40 minutes, one pan to wash.
Costco Lasagna from Scratch
Costco Lasagna from Scratch
Homemade lasagna from Costco ingredients is the ultimate value meal: Kirkland Italian sausage, Rao's marinara, a large tub of Costco ricotta, and shredded mozzarella. This recipe fills a full 9x13 pan and feeds 12 people generously — at a cost that's hard to beat. It takes about 90 minutes total but most of that is hands-off oven time.
Costco Pulled Pork Sliders
Costco Pulled Pork Sliders
Pulled pork sliders on King's Hawaiian rolls are the ultimate party food, and everything you need comes from Costco: a bone-in pork shoulder, King's Hawaiian slider buns, and your choice of BBQ sauce. The pork slow-cooks all day while you're at work, then all you do is pull it and pile it onto the rolls. Add a quick coleslaw and dinner for 12 is done.
Herb-Butter Roasted Turkey Breast
Herb-Butter Roasted Turkey Breast
Costco sells bone-in turkey breasts in the 5–7 lb range, perfect for smaller gatherings or anyone who prefers white meat. The method here focuses on herb-compound butter pushed under the skin, which bastes the meat from the inside as it roasts, keeping it juicy and deeply flavorful. Roasting at 325°F until the thickest part reaches 165°F produces consistently moist results without a brine or basting every 20 minutes.
Classic Cottage Pie (Shepherd's Pie with Beef)
Classic Cottage Pie (Shepherd's Pie with Beef)
This hearty cottage pie uses Costco ground beef as the base, layered with frozen mixed vegetables and a rich, savory gravy, then topped with creamy mashed potatoes and baked until golden. Everything comes from a Costco run — the large packages of ground beef and russet potatoes offer excellent value and make this easy to scale up for batch cooking or meal prep. It reheats beautifully, making it a smart choice for feeding a family through the week.
Garlic-Herb Crusted Pork Loin Roast
Garlic-Herb Crusted Pork Loin Roast
Costco sells boneless pork loin roasts in the 3–4 lb range, and they are one of the best values for feeding a crowd — mild, lean, and forgiving enough for a weeknight roast. A quick sear in a hot oven-safe pan builds a crust before finishing in a 375°F oven to 145°F internal temperature. A garlic-herb paste applied before searing drives flavor into every slice. This recipe feeds 8 and the leftovers are excellent for sandwiches, grain bowls, and fried rice.
Big-Batch Costco Vegetable Soup
Big-Batch Costco Vegetable Soup
Costco is ideal for big-batch soup: their bulk bags of carrots, celery, and zucchini, canned diced tomatoes, and Kirkland Signature chicken or vegetable broth make it economical and easy to fill a large pot. This soup is loaded enough to be a main course, with cannellini beans adding protein and body so it satisfies without feeling thin. It freezes beautifully in individual portions, making it one of the best meal-prep recipes in the rotation.
Elevated Kirkland Madras Lentils
Elevated Kirkland Madras Lentils
Kirkland Signature Madras Lentils are a Costco staple: pre-cooked black lentils and kidney beans in a rich, spiced tomato sauce. But eaten straight from the pouch, they can taste a little flat and processed. This recipe treats the pouch as a high-quality base and builds around it — caramelizing onions low and slow, blooming cumin, coriander, and garam masala in butter, then folding in the lentils and finishing with a splash of heavy cream. The result tastes deeply homemade, and the whole process takes under 30 minutes.
Costco Tortellini Pasta Salad
Costco Tortellini Pasta Salad
Costco's refrigerated cheese tortellini is a meal-prep powerhouse — it cooks in under 10 minutes and holds up well chilled for days. This pasta salad leans into Italian deli flavors: briny kalamata olives, marinated artichoke hearts, pepperoncini, fresh cherry tomatoes, and a tangy Italian vinaigrette made in minutes. It serves 8 generously and actually tastes better after a few hours in the fridge, making it perfect for potlucks, lunches, or a week of easy dinners.
