Ingredient notes
- Taco seasoning - make a batch of my homemade taco seasoning or use store bought as a shortcut.
- Ground meat - turkey or beef works great for this recipe; swap for extra black beans if you want to make it vegetarian.
- Tortillas - I used organic wheat & corn tortillas, but multigrain or original tortillas would work great as well; we've used 6 inch tortillas but you can cut what you have to fit the baking dish.
- Cheese - mozzarella cheese or Monterey Jack works perfectly in this recipe
- Black beans - you can used canned, or make a batch of black beans on the stove top or in the Instant Pot.
Step by step directions
1. Prep - Heat oven to 350°F. Spray a deep 9 x 9 inch baking dish with spray oil and set aside.
2. Cook meat - in a large pan sauté the ground meat, breaking it up with a spatula. Cook until no longer pink (around 10 minutes). Drain excess liquid and transfer to a large bowl.
3. Add ingredients - to the bowl, add the diced tomatoes, taco seasoning, bell pepper, corn, and optional black beans. Mix it up until well combined.
4. Assemble casserole - layer the casserole in the baking dish: Start by covering the base with tortillas (arrange them so there are no holes). Next, add ⅓ of the mixture from the bowl. Sprinkle with ⅓ of cheese. Repeat with all remaining ingredients, finishing with cheese.
TIP- I used this 9 x 9 inch baking dish
Note: at this point, you can freeze your casserole for later (uncooked) or enjoy it right away. See freezer meal prep instructions below.
5. Bake - cover casserole and bake for 20 minutes. Uncover and bake for another 10 minutes. Let casserole stand 5-10 minutes before serving. Enjoy with tortilla chips, avocado slices, or greek yogurt.
FAQ
I cut them in halves and quarters and arrange them (see photo above) to cover any gaps or holes.
Absolutely! Skip the ground meat and be sure to include the black beans.
If freezing (uncooked) this casserole will last for up to 3 months. It will last in the fridge for up to 4 days once cooked, but is best enjoyed within the first 2-3 days as the tortillas do get mushy as it sits.
