Mexican Tortilla Casserole brings taco-night flavors to one baking dish: seasoned ground beef, creamy refried beans, cooked rice, corn, chunky salsa, and melted cheddar tucked between soft flour tortillas. The beans help the layers hold together, while the salsa keeps the filling moist. After a short rest, you can cut the casserole into wedges and let everyone add their favorite toppings.
There is no need to roll individual tortillas. Brown the beef, spread the fillings in layers, and bake until the center is hot and the cheese is bubbling. Mild salsa makes a gentler version; a hotter salsa gives the same casserole more kick.
Ingredients for Mexican Tortilla Casserole
- 1 pound lean ground beef: brown it with the onion, then drain excess grease.
- ½ cup diced onion: small pieces soften as the beef cooks.
- 1 packet taco seasoning: use a 1-ounce packet and the amount of water directed on its label.
- 2 cups shredded cheddar: divide it between the layers and the top.
- 1 can refried beans: a 15-ounce can, warmed just enough to spread easily.
- 1 cup prepared rice: measure it after cooking. Plain white rice or Spanish rice both work.
- ½ can Mexican-style corn: half of a 15-ounce can, about 7.5 ounces, drained well.
- 4–5 large flour tortillas: four make the main layers; a fifth is optional.
- 8 ounces thick chunky salsa: choose mild, medium, or hot.
- Optional toppings: sour cream, diced red onion, chopped tomatoes, shredded lettuce, or cilantro.
Have the rice cooked before you begin assembling. Warm the beans gently and stir them until smooth; cold, firm beans can drag and tear a tortilla. Thick salsa and well-drained corn help the finished wedges hold their shape.
How to Make Mexican Tortilla Casserole
Brown and season the beef
Heat the oven to 350°F (175°C). Lightly grease a deep, oven-safe round dish that fits your tortillas. A round cake pan or springform pan can also work if it is deep enough to hold the layers. Trim or tuck tortilla edges as needed so they lie mostly flat.
In a large skillet over medium heat, cook the ground beef and diced onion until the beef is fully cooked. Break up larger pieces as you stir. Drain excess grease, add the taco seasoning and the water called for on the packet, then simmer until the mixture is thick rather than soupy.
Start with beans, beef, and cheese
Lay the first tortilla in the prepared dish. Spread one-third of the warmed refried beans across it, reaching close to the edges. A thin, even coating is easier to slice than a mound of beans in the center.
Scatter one-third of the seasoned beef over the beans and add some cheddar. Keep a generous portion of the cheese for the final topping; the smaller amounts inside the casserole help bring the filling together.
Add the rice, corn, and salsa layer
Place a second tortilla over the beef layer. Add half the cooked rice, half the salsa, and all of the drained corn, then sprinkle with cheddar. Spread the filling evenly so the middle layer is the same thickness across the dish.
Finish the remaining layers
Add the third tortilla, followed by another one-third of the beans and one-third of the beef, plus a little cheese. Set the fourth tortilla on top and spread over the remaining beans, beef, rice, and salsa. Finish with the remaining cheddar.
If you use a fifth tortilla, divide that last portion of filling between the fourth and fifth tortilla layers, then finish with cheese. You are spreading the same ingredients over an extra layer, so there is no need to add more filling.
Bake covered, then uncover
Cover the dish with foil and bake for 40 minutes. Remove the foil and bake for another 10–15 minutes, until the center is hot and the cheese is melted and bubbling. Keep an eye on the exposed tortilla edges during this final part of baking; they should be lightly toasted rather than dark.
Let It Rest, Then Serve
Let the casserole stand for at least 5 minutes before cutting. This brief rest lets the filling settle, making it easier to lift a wedge without losing the middle layers. Cut through to the bottom tortilla and slide a broad spatula underneath each portion.
Add sour cream, diced red onion, or chopped tomatoes at the table. The casserole already contains beef, beans, and rice, so a crisp salad or sliced avocado makes a simple accompaniment. Plan on about 8 servings; this is an estimated yield, and the portion size can change depending on what you serve alongside it.
Tips for Better Layers
- Start with a thick meat mixture. Simmer off excess liquid before assembling so it does not collect at the bottom.
- Spread each filling to the edges. Even layers give every wedge a little of everything.
- Keep the tortillas flat. Folded or bunched edges can make the casserole harder to cut.
- Save cheese for the top. Divide the 2 cups between the inner layers and the final topping.
- Give it the full resting time. Cutting straight from the oven makes the layers more likely to slide.
Frequently Asked Questions
Can I add uncooked rice?
No. This recipe calls for 1 cup of rice that is already cooked. There is not enough added liquid to cook dry rice evenly inside the casserole. Prepare the rice first, then measure the amount you need.
How spicy is this casserole?
That depends mostly on your taco seasoning and salsa. Choose mild versions for a gentler flavor, or use medium or hot salsa if you prefer more heat. The amount of salsa stays the same.
Do I need a springform pan?
No. A deep round casserole dish or round cake pan works too. Choose an oven-safe pan with enough depth for the stacked tortillas and filling, and grease it before assembling. A springform pan is optional, not a requirement for serving wedges.

Mexican Tortilla Casserole
Ingredients
- 1 lb. ground beef lean
- 1/2 cup onion diced
- 1 packet taco seasoning mix 1-ounce packet; water as directed on the packet
- 2 cups cheddar cheese shredded; divided between the layers and topping
- 1 can refried beans 15 ounces; warmed for easier spreading
- 1 cup prepared rice already cooked; white or Spanish rice
- 1/2 can Mexican-style corn half of a 15-ounce can (about 7.5 ounces), drained
- 4-5 large flour tortillas
- 8 oz thick chunky salsa mild, medium, or hot
- Optional toppings sour cream, diced red onion, shredded lettuce, cilantro, or chopped tomatoes
Instructions
- Preheat the oven to 350°F (175°C). Lightly grease a deep, oven-safe round casserole dish, round cake pan, or springform pan that fits the tortillas and has room for the stacked filling. Trim or tuck tortilla edges to fit.
- In a large skillet over medium heat, cook the ground beef and diced onion until the beef is fully cooked, breaking it into small pieces. Drain excess grease. Add the taco seasoning and water according to the packet directions. Simmer until the mixture is thick rather than watery.
- Place the first tortilla in the prepared dish. Spread one-third of the warmed refried beans over it, add one-third of the beef mixture, and sprinkle with some cheddar. Reserve a generous portion of the cheese for the final topping.
- Add the second tortilla. Spread half of the cooked rice, half of the salsa, and all of the drained corn evenly over it. Sprinkle with some cheddar.
- Add the third tortilla, another one-third of the beans, and another one-third of the beef. Sprinkle with some cheddar.
- Add the fourth tortilla and top with the remaining beans, beef, rice, and salsa. Finish with the remaining cheddar. If using a fifth tortilla, divide this last portion of filling between the fourth and fifth tortilla layers, then finish with the cheese.
- Cover the dish with aluminum foil and bake at 350°F (175°C) for 40 minutes.
- Remove the foil and bake for another 10–15 minutes, until the center is hot and the cheddar is melted and bubbling. Watch the exposed tortilla edges so they do not become too dark.
- Let the casserole rest for at least 5 minutes before cutting into wedges. Slide a broad spatula under each serving. Add optional toppings as desired and serve hot.
