13 Costco Dinner Ideas Perfect for Busy Weeknights

You know those weekdays when you shut down your laptop or take that first step of relief into your home and make a beeline for the bedroom to shed the uncomfortable clothes for the cozy ones? And then, there's dinner to be made. Soothe that tension and hunger with these easy Costco dinners that come together in a snap.

Grab a bag of salad, your favorite salad toppings, and a Costco rotisserie chicken. Oh, and some buffalo sauce. Once you get home, cut up, shred up, or otherwise poorly butcher the rotisserie chicken. In a bowl, add the amount of chicken you'd like with the amount of buffalo sauce that speaks to your soul. Toss and coat the chicken thoroughly.

Sprinkle your spicy chicken over your prepared salad. Consider ranch or blue cheese dressing, but green goddess is a solid choice, too.

If you're feeling ambitious, bag up the remains of the chicken and pop it all in the freezer to make soup. On the weekend, when you've got a bit more time of course. The best Costco dinners feed you more than once, after all.

Not only do these ham and cheese sliders make for the quickest, easiest dinner, but you can also consider this meal prep because the leftovers are incredible. Personally, I toss these in the toaster oven to warm them up for the perfect snack between meals, too.

They're easy to make.

1. Slice some Hawaiian rolls in half lengthwise and put the bottom halves in a 9-inch square baking dish.
2. Take some Costco deli ham and Costco deli Swiss and put them on the bottom of the rolls.
3. Then, add the tops of the rolls.
4. Brush with melted butter and sprinkle with poppy or sesame seeds.
5. Bake in a preheated 350°F oven for 25 minutes.

If you're feeling fancy, spread the bottom rolls with dijon mustard before adding the ham and cheese. Yum.

Serve with a salad or some cut-up veggies for a well-rounded meal. (Or just pair these with a V-8 juice, we don't judge.)

Snag a package of Costco's prepared birria, your preferred taco shells (because that's a personal choice), and a few taco toppings. We suggest some white onion and cilantro. If you think cilantro tastes like soap, there's something about the magic of birria that cancels out the suds flavor. You're going to want to grab some shredded cheese from the dairy aisle, too.

Heat up the birria according to directions, then load up your warmed tortillas or taco shells with the birria and toppings. Your Costco weeknight dinner is complete with a scoop of rice.

Open up some Costco prepared gyro, naan, and tzatziki. Shred some lettuce and chop some onion (thinly slice a tomato and cucumber too, if you're feeling fancy), and you have a tasty dinner in minutes. Warm up the gyro according to the package and then chomp away. Skip the bread and make yourself a gyro bowl by using extra lettuce, adding rice, and giving yourself an extra drizzle of tzatziki.

With your package of Costco naan, build yourself a pizza. Slather on prepared pizza sauce, and sprinkle on Costco grated cheese of your choice. If you're feeling up to it, you can add your favorite toppings. We suggest Costo's pre-cooked bacon, but you do you. Pop it into a 350° oven until the cheese is gooey (8-10 minutes) and perfect. Don't burn your mouth on that first bite.

Your protein will be ready with no prep from you thanks to Costco stuffed chicken breasts. Take that time to microwave some veggies or throw a quick salad together, or whatever you're feeling in your soul that night.

And clean up? If you put some foil under the chicken and microwave the vegetables in a bag, you'll have only your plate and silverware to wash.

Have some breakfast for dinner but make it bougie. Fry up an egg and add your favorite breakfast protein to a Costco croissant to make a breakfast sandwich. Make it even easier on yourself by scrambling eggs instead of fighting a sunny side-up egg. Don't forget to stir in some cheese.

Pro Tip: Add a slice of ham or a few slices of bacon, because they're delicious. Lettuce and tomato are optional.

Meander to Costco's pasta aisle for spaghetti and jarred sauce, and don't forget to head to the frozen section to grab yourself some Costco meatballs. Cook all according to the package instructions and then stir together to have a cozy meal without doing much work.

Of course, you can doctor your pasta sauce with some extra spices, maybe some garlic. Perhaps a side of garlic bread, too. You can get that in the frozen aisle and heat it up while the pasta is cooking. 

A loaf that's meaty enough to feed a family of four (although serving sizes are debatable), a Costco meatloaf will likely leave you with plenty of leftovers. Pair it with a salad, maybe some mashed potatoes or fresh bread, and your dinner is served.

For one of the easiest and most satisfying Costco weeknight dinners, make up a Caprese grilled cheese. Grab a loaf of Costco bread. Any bread will do. Swing by the cheese section to grab a log of mozzarella, and don't forget some balsamic glaze, prepared pesto, and fresh tomatoes.

Pile your supplies between the bread, and then toast until your sandwich is nice and melty.

Costco offers plenty of precooked shrimp, and those are excellent for easy weeknight dinners. Add your warmed shrimp to a rice bowl with with greens, avocado, mango, and rice. Toss your shrimp into salad or into a garlicky pasta dish. The hardest part is not relying on this every night for a quick dinner.

Don't take too long to browse for a Costco frozen pizza - start off with a simple frozen cheese pizza. Once you get home, you can load that pie up with your favorite toppings. Better yet, keep one on hand in your freezer, and you can have a loaded topping pizza whenever you need to clear out your fridge.

Pro Tip: Once you've added your toppings, sprinkle a thin layer of extra mozzarella on top of everything before baking. You're welcome. 

I'll be honest, Costco sausages are my number one item that I always keep on hand. And I mean always. Cooked up whole, you can enjoy these on a roll with some peppers and onions. Or eat them with a fork and knife next to some veggies and a baked potato. Slice these up and cook them, and they go beautifully with pasta. Oven, stovetop, or grill, these sausages mean your weeknight dinner is ready in no time.

You have better things to do after a long day of work and everything else. Cut down the time from cooking to eating so you have more time for things that matter. Like that new tv show or some much-needed you time.
