How to Build a Taco Casserole:

Taco casserole is layered in a slow cooker to create a delicious casserole. Ingredients can be changed to what your family prefers.

  • First Layer – We prepared white rice to layer at the bottom of the slow cooker. But you can easily use brown rice or flour tortillas. There are also many gluten free options.
  • Second Layer – The second layer is the taco filling. We prepared the ground beef in a skillet and then added in corn, black beans and diced tomatoes for added flavor. Season this taco mixture with taco seasoning. Once these ingredients are cooked together, layer it on top of the white rice.
  • Third Layer – This final layer is one of my favorite parts. Top the meat mixture with cheese and let this all heat together in the slow cooker. Dish and serve and top with diced avocados and salsa.
Ingredients needed - ground beef, onion, corn, black beans, diced tomatoes, taco seasoning, garlic salt, cooked rice, cheese

  • Diced Tomatoes with Green Chiles (aka Rotel)

How to Make Taco Casserole in the Crock Pot:

  • Step 1 – Cook Meat Mixture – First brown your ground turkey or ground beef in a large skillet over medium high heat.  Then add in the chopped onions, taco seasoning, tomatoes, beans and corn.
  • Step 2 – Stir and Combine – Stir to combine all these ingredients and set aside

Do you brown Ground Beef before putting in Slow Cooker?

In this recipe, we recommend browning the ground beef before placing in the slow cooker. This prevents the meat clumping up and from adding grease to the recipe.

There are some crock pots that you can cook the meat directly in the slow cooker. But we prefer to combine the meat mixture in a skillet to cook.

Taco Casserole Topping Ideas:

These are our favorite toppings but feel free to use what you prefer.

  • Green Onions
  • Tomatoes
  • Avocados
  • Sour Cream
  • Lettuce

Also you can top this casserole with tortilla chips or Fritos to make crock pot taco casserole with Fritos.

This recipe will surprise you. It doesn’t seem like much, but it has some amazing flavor.

How to Make Homemade Taco Seasoning:

We love to make homemade taco seasoning. It is so simple and easy. I keep this on hand and it makes a big batch. You will save so much money making this at home.

It is so nice not having to buy the little packets all the time at the grocery store. Plus, I love knowing exactly what is in the taco seasoning. Store bought taco seasoning as ingredients that we can’t even pronounce.

Crockpot Taco Casserole Variations

  • Add shredded chicken instead of the beef
  • Use Salsa verde or green enchilada sauce instead of the Rotel
  • Try kidney beans instead of the black beans
  • Try adding in ½ cups of bell peppers or jalapeños

As you can see you can make this delicious crock pot Mexican taco casserole several different ways for more easy dinner ideas.

Can Taco Casserole be prepared ahead of time?

Taco casserole can easily be prepared ahead of time. This would be a great recipe to use leftover ground beef. Place the ground beef, seasoning, beans and corn in the skillet. Once cooked and combined let cool to room temperature.

Place the meat mixture in a air tight container and place in the fridge. Prepare the rice and store in a container and place in the fridge.

Once you are ready to prepare, layer the cooked ingredients in the slow cooker and heat. This would be perfect to make for a party and then heat.

Can I Make in the Oven?

  1. 5 stars
    The results are delicious and I never had to eat up the kitchen with the oven.

    1 cans of diced tomatoes with green chilis (aka rotel)

  2. When you list the nutrition information for this recipe, what is the serving size?

  3. This recipe serves 10, so the nutritional information is for 1/10 of the entire recipe. Thank you.

  4. Do you have to cook this in a crockpot? If I just use a stock pot to mix everything together including the rice how long would I have to let it simmer?

  5. 5 stars
    I put this together and put in the freezer for later. I thawed and heated in the oven and it was a big hit with the whole family. Thanks for making me look like such a good cook lol

  6. I think that it could be made in the an instant pot but I haven’t tested it out yet. If you try it out, please let us know how it turns out!

  7. Could I cook the rice in the crockpot as well so there’s less steps and dirty dishes? If so, how long?

  8. I don’t recommend that for this recipe as I think that the rice would get too mushy in this recipe. I find that using pre-cooked rice works best in this recipe.

  9. I love cauliflower rice but I think it might get over cooked in the crock pot. I would leave the rice over and cook the cauliflower rice separately and then serve it over the cauliflower rice instead. I hope enjoy it!

  10. 5 stars
    This was a big hit for my son he finished it off in 2 days .I made in oven and served with chips I sent this recipe to my friend we share recipes and they enjoyed it also .thank you

  11. Just wondering if I can use cauliflower rice instead? If I do, should I just cook rice separately?
