Healthy Mexican Casserole with ground turkey, veggies and beans layered between tortillas and baked until gooey cheese on top. A healthy comfort meal loaded with classic Mexican flavors!
Mexican casserole with tortillas has layers of juicy seasoned meat, sauteed peppers and mushrooms, beans, and a tasty tomato sauce. All in one bite- like deconstructed Mexican stuffed peppers!
Busy weeknights are no match for this easy Mexican casserole because it is a great make ahead meal to have ready to pop in the oven an hour before you’re ready to eat. Have it on the weekend for a lazy Sunday dinner and have leftovers for lunch the next day.
This is the best casserole for serving a crowd. Your guests will be so impressed at how delicious it is and never know how easy it really is. In fact, I love to serve up one-pot meals whenever I can; lazy cabbage rolls, chicken burrito skillet, ground turkey skillet… there are tons to choose from!
Ingredients for Healthy Mexican Casserole
- Ground meat: You can use ground turkey, chicken, or beef. Your choice will alter the flavour of the dish slightly, but either choice is just as delicious.
- Veggies: Chopped onion, minced garlic, chopped bell peppers, sliced mushrooms. You can also use whatever veggies you have in your fridge. This recipe is very flexible so use whatever you’d like!
- Seasonings: Low sodium taco seasoning, chili powder, cumin, salt, pepper, and a pinch of cayenne.
- Oil: For frying. Can use olive oil, coconut oil or I use avocado oil.
- Beans and corn: Low sodium canned beans, Instant Pot black beans or cooked dried beans. Can replace with Instant Pot refried beans or dried beans. Fresh, frozen, or canned corn.
- Spice: Diced green chiles. You can also use minced jalapeno. Remember the heat comes from the seeds! The amount is at your discretion.
- Tomato sauce: Low sodium plain tomato sauce.
- Cheese: Cheddar, Tex Mex, or Colby shredded cheese. Grate your own – it melts better.
- Tortillas: Small corn tortillas. You can also use regular flour tortillas. Corn tortillas are thicker, and sturdier and will hold up to moisture better than flour tortillas will. The difference will be in the texture and taste of the casserole.
- Optional garnish and toppings: Green onion, cilantro, lime, yogurt/sour cream and avocado (or guac).
- Cooking spray: I use Misto, but you can use what you have.
How to Make Mexican Casserole
- Prep: Preheat the oven and spray a large baking dish with cooking spray. This casserole is tall, so make sure to use a deep dish (they vary!). Preheat a large non-stick skillet and swirl oil to coat.
- Saute: First saute onion and garlic for a few minutes. Then add bell pepper and mushrooms for a few minutes. Sauteing in stages helps to avoid extra moisture and achieve fragrant veggies. Transfer to a large bowl.
- Add meat: Now cook ground turkey, constantly stirring and breaking up the meat. Once fully cooked through, transfer to the bowl with the veggies.
- Combine everything: Add remaining ingredients to the bowl: taco seasoning, chili powder, cumin, salt, pepper, a pinch of cayenne, black beans, green chiles, corn, and most of the tomato sauce. Stir well.
- Layer: Lay 6 tortillas in prepared baking dish. They will overlap a bit. Spread half of the meat/veggie mixture, topping with 4 tortillas. Top with more meat/veggie mixture, finishing with 6 tortillas overlapping. Spread remaining tomato sauce on top.
- Bake: Cover the dish and bake until almost done. Uncover and sprinkle with cheese, baking uncovered until cheese has melted.
- Cool: Remove from the oven and let stand. Allowing it to cool to warm will allow for neater slices. Garnish with optional green onion and cilantro. Cut into slices with a serrated knife and serve warm with lime wedges, diced avocado, and yogurt/sour cream.
Variations and Substitutions
- Substitutions: Sub corn tortillas with 3 cups Instant Pot quinoa. Use Rotel, a delicious blend of tomato and green chili, in place of tomato sauce. Replace ground meat with 3 cups of cooked meat like pressure cooker shredded chicken.
- Vegetarian: Omit the meat or use crumbled tofu/meat substitute and you’ve got yourself a vegetarian Mexican casserole!
- Level up: In place of avocado, make delicious guacamole.
- Leftovers: If you have leftover meat and veggie mixture, use it as a topping for nachos, inside tacos, chicken burritos, or a delicious topping to lettuce salad recipe!
How to Store, Freeze and Reheat
Storing: Refrigerate leftovers in an airtight container for up to 3 days.
Freezing: If you are making it ahead of time, allow assembled and unbaked casserole to cool completely. Wrap in two layers of plastic wrap and cover with aluminum foil. Freeze for up to 3 months. If freezing leftovers, store in an airtight freezer friendly container.
Reheating: Allow casserole to thaw on the counter for 45 minutes to prevent the dish from shattering. Then bake as per recipe adding about 20 minutes. If casserole is cooked, reheat in the oven while covered for about 20 minutes at 350 degrees F.
