Your whole family will thank you for making this simple taco casserole since it’s just so tasty. Like, they’re going to get really excited for next taco night. It’s also super customizable, so everyone can load it up with their favorite toppings!

Ingredients you’ll need

  • Doritos – use your favorite flavor. I picked nacho cheese. You can also add some on top for an extra crunch!
  • Onion – makes a great savory base
  • Chili powder, garlic powder, ground cumin – this trio makes a delicious homemade taco seasoning
  • Beans – I prefer black beans, but you could do a layer of refried beans instead!
  • Corn – we’re using canned corn to make this hassle free
  • Salsa – pick up a jar of your preferred brand
  • Cheese – I used a Mexican blend, but cheddar would work great

Suggested toppings:

  • Fresh tomatoes
  • Chopped cilantro and scallions
  • Avocado or Guacamole
  • Black olives
  • Sour cream or plain Greek yogurt
  • Iceberg or romaine lettuce

How to make taco casserole

This is an overview with step-by-step photos. Full ingredients & instructions are in the recipe card below.

cooking ground beef with onion and spices in a cast iron skillet

Preheat the oven to 350. In a cast iron skillet cook the beef in the olive oil. After about 5 minutes, stir in the onion and spices. Continue cooking, and then spoon out any excess fat.

adding in corn, cheese, salsa, and black beans

Add in the corn, salsa, beans, and half the cheese. Warm until the cheese melts.

adding doritos and beef mixture to a casserole dish

Place an even layer of Doritos in a 9×13 baking dish. Spoon the beef mixture over top.

Top the casserole with the remaining cheese, and then bake uncovered for about 15-20 minutes or until hot and melty! Serve as-is or with toppings of your choice.

Can I make taco casserole ahead of time?

  • You bet! Simply cook the onion, spices, and beef mixture, assemble the layers in a baking dish, let it cool, and then tightly cover.
  • It’ll keep in the fridge for a day or two, or you can freeze it for up to a month.
  • If frozen, thaw in the fridge overnight before baking. Since it’ll be starting out cold, it’ll need a bit more time than in the original instructions. Cover with foil and bake for 20 minutes, and then uncover it cook for another 15 minutes or so until it’s hot.
  • These disposable aluminum baking pans are perfect if you’re bringing it to a potluck or making several.

Substitutions and variations

  • You don’t have to use Doritos. Other tortilla chips or Fritos will definitely work in this taco bake!
  • Use a ready-made taco seasoning blend if you prefer not to use the individual spices.
  • You could add more veggies such as red bell peppers to this casserole. I’d add them in at the same time as the onion. 
  • Feel free to swap the black beans with another kind if you prefer, like kidney beans or pinto beans. 
  • If you want to add some heat, use a medium or spicy salsa, hot cheese blend, add some cayenne pepper, or you could even toss in some spicy chopped green chilies. 

Leftovers and storage

  • If you have any leftovers, they will keep in the fridge for 2-3 days in a covered container. Keep in mind the Doritos will lose firmness over time.
  • Reheat in the oven for best results, but you can also microwave until heated through.
  • Leftovers can also be frozen. I portion them up in individual containers.

    Great recipe! I did a few substitutions, though ground turkey as it has less fat and is healthier, added five chopped Roma tomatoes for color and flavor, added a bag of frozen red, green, and yellow peppers on sale at the $.99 store, used frozen fire-roasted corn instead of canned, I really like the flavor. Also, I used blue corn tortilla chips, less salt and no artificial ingredients. Huge hit at our monthly church food making fest, and we made several more casseroles to provide meals for the homeless. Love your recipes, thanks!

      You are very welcome, Laurie!

    Hi Natasha! Just tried to do a review and it like disappeared. 😱🤪 At best I would call myself a hesitant cook. I had to make a casserole to take to a widows group at church. Lutheran women are a tough crowd because they’re all great cooks. I put the casserole together the night before except for the chips and then I got up the next morning and finished the casserole. This was a great recipe. It goes together fast and easy, it tastes great, and was fun. Thanks so much. I’m checking out more of your recipes since everyone prefers to take desserts ha ha ha.

    We enjoyed this recipe. I didn’t put Doritos on the bottom, but put tortilla chips on top with chopped tomatoes and avocado. I had some leftover rice and put that in bottom of bowl with casserole on top. Soooo good.
