Step 1: Prepare Your Baking Dish

To begin, preheat your oven to 350°F (175°C) and spray a spring form, round cake pan, or casserole dish with cooking spray. This will prevent the casserole from sticking to the dish.

Step 2: Brown the Ground Beef

In a large skillet, brown the ground beef along with the diced onion. Once the beef is cooked through, drain any excess fat.

Step 3: Add Taco Seasoning

Now, add the taco seasoning mix to the cooked beef according to the package directions. This will infuse the beef with delicious Mexican flavors.

Step 4: Start Layering

It’s time to create the layers of your Mexican Tortilla Casserole. Follow these steps:

Place one tortilla in the bottom of your prepared baking dish.

Spread one-third of the refried beans over the tortilla.

Add one-third of the seasoned ground beef on top of the beans.

Sprinkle some shredded cheddar cheese over the meat.

Step 5: Continue Layering

Repeat the layering process with the remaining ingredients:

Place another tortilla over the cheese.

Add half of the prepared rice.

Spread half of the chunky salsa evenly.

Sprinkle half of the drained Mexican blend corn and more cheese.

Step 6: Final Layers

Continue building your delicious casserole:

Place a third tortilla.

Add the remaining refried beans and ground beef.

Top it off with more cheese.

Step 7: Bake to Perfection

Cover your casserole dish with foil and bake it in the preheated oven for approximately 40 minutes. Then, uncover it and bake for an additional 10-15 minutes until the top is golden and bubbling.

Step 8: Serve and Enjoy

Allow the casserole to sit for about 5 minutes before cutting into it. Once plated, feel free to top it with sour cream, diced onion, and shredded lettuce according to your preference.
