This easy Taco Casserole recipe is the ultimate weeknight comfort food. It’s a savory ground beef casserole filled with all of your favorite Mexican flavors! Made from tender beef cooked with zesty tomatoes, poblano peppers, and spinach, then layered with tortillas and lots of cheese.

A Cheesy and Easy Taco Casserole Recipe

Taco night is always a hit at our house, but sometimes I like to switch things up from the usual tortillas and toppings. This taco casserole turns all those familiar flavors into an easy baked dinner with layers of soft flour tortillas, seasoned ground beef, spinach, veggies, and plenty of cheese.

It’s hearty, cheesy, and easy to assemble ahead of time, which makes it especially good for busy weeknights. I do the same kind of switch-up with my taco pizza, where seasoned beef, refried beans, salsa, and cheese get piled onto a crispy pizza crust instead.

Why You’ll Love This Mexican Casserole 

• Easy to make. Cook the filling, layer everything with tortillas and cheese, and bake until hot and bubbly.
• Loaded with taco flavor. Seasoned ground beef, veggies, soft tortillas, and plenty of melted cheese come together in every layer.
• Make it your own. Change up the veggies, cheese, and toppings just like you would with your favorite taco bowls.
• Great for leftovers. It reheats well, so tomorrow’s lunch is taken care of, too.

What You’ll Need

Below is a quick look at some of the key ingredients you’ll need to make your easy taco casserole. Be sure to scroll down to the recipe card for a full ingredient list and detailed instructions.

• Tortillas: Soft flour tortillas are best for this recipe, though soft corn tortillas will also work. You can use regular, low-carb, or whole-grain tortillas.
• Ground Beef: I use lean ground beef, but you can make this casserole using any ground meat you’d like. Ground chicken, like in my quinoa enchilada casserole, or ground turkey would also be delicious.
• Veggies: This recipe adds juicy diced tomatoes, spinach, and poblano peppers for a Tex-Mex kick. The veggies you add to the filling are also totally customizable (see the variation ideas later in the post for suggestions!).
• Cheese: Two types of shredded melty cheese really amps up the flavor and ooey-gooey factor of this casserole.

Serving Suggestions

This taco casserole is filling on its own, so a few simple Tex-Mex sides and toppings are all you need to round out the meal.

• Toppings. Serve it with sour cream and fresh restaurant-style salsa.
• Rice. Add a side of fiesta rice or keep things simple with cauliflower rice.
• Chips and guacamole. Crunchy tortilla chips with mango guacamole make an easy side or appetizer.
• Corn. Serve elote on the side, or try my Mexican street corn salad.
• Dessert. Finish with a batch of Mexican hot chocolate fudge.

Resting Time: 10 minutes minutes

Total Time: 1 hour hour

Servings: 6 servings

Ingredients 

1x2x3x

For The Casserole

• ▢ 2 tablespoons olive oil
• ▢ 1 small poblano pepper, diced
• ▢ 3 cloves garlic, minced
• ▢ 1 pound lean ground beef
• ▢ 1 teaspoon chili powder, or to taste
• ▢ ½ teaspoon ground cumin
• ▢ ¾ teaspoon salt, or to taste
• ▢ ¼ teaspoon freshly ground black pepper, or to taste
• ▢ 2 large fresh tomatoes, diced
• ▢ 9 ounces fresh baby spinach
• ▢ 1 cup shredded cheddar cheese
• ▢ 1 cup shredded Monterey jack cheese
• ▢ butter for dish
• ▢ 4 eight-inch flour tortillas

For Serving, Optional

• ▢ avocado Slices
• ▢ cherry tomatoes
• ▢ tortilla chips

Instructions 

• Prep. Preheat the oven to 350˚F and coat a 2-quart or 3-quart baking dish with butter. Set aside.
• Sauté the peppers and garlic. Heat the olive oil in a large skillet set over medium-low heat. Add the diced poblano and cook for 3 minutes, or until just tender; stir in the garlic and cook for 15 seconds or until fragrant.
• Cook the ground beef. Stir in the beef and season with chili powder, ground cumin, salt, and pepper. Cook until the meat is browned, stirring occasionally to break it up, about 6 minutes.
• Add the vegetables. Stir in the diced tomatoes and continue to cook for 2 minutes. Add the fresh spinach and cook for 1 to 2 more minutes, or until wilted. Remove from heat.
• Combine the cheese. In a bowl, mix the shredded cheeses and set aside.
• Layer the casserole. Cover the bottom of the baking dish with a layer of the meat sauce. Top with 1 flour tortilla and sprinkle shredded cheese over it. Repeat the layers, and top each layer with the meat mixture and cheese before adding the next flour tortilla. Finish by spreading the remaining meat mixture on top and adding the remaining cheese.
• Bake. Cover the casserole and bake for 30 minutes; remove the cover and continue cooking for 5 to 8 more minutes, or until bubbly.
• Let it cool, then serve. Remove the taco casserole from the oven and let it stand for 10 minutes; garnish with avocado slices, cherry tomatoes, and tortilla chips, then serve.

Notes

• Make Ahead: This casserole can be prepared 1-2 days ahead. Brown the meat and layer the casserole in a baking dish following the recipe. Cover tightly and refrigerate the unbaked casserole and bake as directed whenever you’re ready!
• Seasoning: Make your own Homemade Taco Seasoning to use in place of chili powder.
• Grate the Cheese: Use freshly grated cheese whenever you can, as the bags of pre-shredded cheese don’t melt as nicely.
• Grease the Baking Dish: Coating the baking dish with butter or Crisco makes scooping, serving, and cleaning much easier.
• Store leftover taco casserole in the fridge for up to 4 days and reheat as needed. It can also be used as a beef burrito filling.
• Freeze the casserole, before or after baking, for up to a month. Thaw in the fridge overnight before baking or reheating, adding extra time if needed.
