Why You’ll Love My Recipe

Flavorful, filling, and easy to make on a busy night, this casserole will satisfy your taco cravings. You can have it made in just half an hour and you’ll barely have to get any dishes dirty!

Why not learn to make your own Taco Seasoning for this recipe? If casseroles aren’t your thing, make some Classic Weeknight Tacos or Taco Sheet Pan Nachos instead. Looking for something with all the taco tastes but don’t need a full meal? Whip up a batch of Bean Dip or Taco Dip.

Karlynn’s Recipe Notes

  • Skill Level: This is a super easy recipe that primarily involves layering ingredients in a casserole dish. Get your kids involved.
  • Total Time: You can have this assembled and cooked in about 30 minutes. Save yourself some time and prep your vegetables in advance.
  • Variations: You can have so much fun changing up this casserole! Try some spicy taco seasoning or fresh hot peppers if you like extra heat. Use ground pork, chicken, or turkey if you prefer those to ground beef. Increase the amount of cheese or use multiple varieties of cheese. Use flavored tortilla chips instead of plain ones. Make a delicious Cheese Sauce to drizzle over top of your casserole, or whip up a Simple Mexican Coleslaw to serve on the side.
  • Tools Needed: As (almost) always with recipes that involve chopped ingredients, you’ll need a good knife and a cutting board of your choice. You’ll also need a large pan for cooking your meat, a 9×13 casserole dish, and a cheese grater (unless you buy pre-grated cheese).

What You’ll Need For Ingredients

Ground Meat: This is an easy area to modify if you would like to reduce fat content. You can use regular ground beef, extra lean beef, ground turkey, ground chicken, etc.

Vegetables: Olives, peppers, an onion, lettuce, green onions, garlic, and anything else you’d like to add.

Tomatoes: In the form of salsa or regular diced tomatoes. This is a good spot for Rotel or something similar.

Cheese: 2 cups of grated cheese, whichever variety you want.

Refried Beans: A 16oz can or the same amount of a homemade version if you happen to have some.

Taco Seasoning: A packet of the store bought stuff is fine, but if you make your own you can add extra spice.

Sour Cream: Whichever fat percentage you prefer.

Tortilla Chips: Technically these are optional, but come on…who doesn’t want that layer of crunch?

How To Make Taco Casserole

This is a brief overview of the recipe. The full list of ingredients and step-by-step instructions are in the recipe card below.

  1. Preheat oven to 350°F. While the oven is preheating, cook your meat, diced red pepper, and diced onion in a pan over medium heat until the meat is cooked through.
  2. Drain the excess grease and then add water and taco seasoning. Simmer for 5 minutes.
  3. Spread refried beans in the bottom of a 9×13 casserole dish, then spread the sour cream evenly over the beans. Add the meat mixture. Sprinkle on the cheese. Bake for 15 minutes.
  4. Add the rest of your toppings and eat while warm.

Karlynn’s Tips and Tricks for Making Taco Casserole

Be Prepared: Gathering your ingredients beforehand can save you a lot of scrambling around the kitchen. Grab your knife and your cutting board and chop up all of your toppings. Store them in individual bowls or containers until your casserole is baked. This is also a great way to let individual family members choose their own toppings! Maybe someone doesn’t want chips on theirs, or someone hates tomatoes.

Make it Extra Spicy: There are many ways that you can add extra heat to this casserole! Stir in some of your favourite hot sauce, or add some chopped hot peppers (fresh or dried). Find a spicy salsa to use in place of tomatoes or as a topping. Choose a spicy taco seasoning or a cheese that has peppers in it. You can also find cans of refried beans that have jalapenos or other peppers added. Canned tomatoes generally have spicy options as well.

Storage Instructions

Since this casserole has nacho chips, it will get soggy quickly if stored in the fridge for a long time, and it is not likely to freeze well.
