Mexican Ground Beef Casserole with Rice is my answer to those nights when I want something warm and filling, but I do not want a bunch of separate pots and pans. You get seasoned ground beef, fluffy rice, black beans, corn, tomatoes, and a generous layer of melty cheese all baked together into one cozy dish. The best part is you can keep it mild for kids, then let the spice lovers add jalapenos or hot sauce at the table. It tastes like comfort food, but it still feels bright and fun because of all the Tex Mex flavors. If you have a busy week, this is the kind of meal that makes you feel like you have your life together.

Mexican Ground Beef Casserole Ingredients
Here is what you will need. I am listing the exact amounts I use so you can shop once and be done with it.
- 1 tablespoon olive oil
- 1 onion, chopped
- 1 bell pepper, chopped
- 3 garlic cloves, minced
- 1 pound ground beef
- 1 tablespoon chili powder
- 1 teaspoon ground cumin
- 1 teaspoon paprika
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 1/2 cups long grain rice, uncooked
- 1 can (10 ounces) diced tomatoes with green chiles
- 1 can (15 ounces) black beans, drained and rinsed
- 1 cup corn (frozen or canned, drained)
- 1 can (8 ounces) tomato sauce
- 3 cups beef broth
- 2 cups shredded cheese (cheddar, Monterey Jack, or a blend), divided
- 1 jalapeno, sliced (optional)
A quick note on the rice: I stick with long grain because it cooks up nicely and does not turn to mush. And on the cheese, use what you love. This is not the time to overthink it.
How to Make Mexican Ground Beef Casserole
This is the part where it all comes together. It is basically a simple sauté, stir, bake situation. Nothing complicated, just a few steps in the right order.
Oven temperature and timing: Bake at 375 F. Covered for 40 minutes, then add cheese and bake uncovered for 10 minutes. Rest for 10 minutes before serving.
- Brown the beef: Heat olive oil in a large skillet over medium high heat. Add ground beef and cook until browned, breaking it up as you go.
- Soften the aromatics: Add onion and bell pepper and cook until they start to soften, about 3 to 4 minutes. Stir in garlic for about 30 seconds.
- Toast the rice and bloom spices: Add the rice, chili powder, cumin, paprika, salt, and pepper. Stir for about 1 minute so the rice gets coated and the spices wake up.
- Add the saucy stuff: Stir in diced tomatoes with green chiles, black beans, corn, tomato sauce, and beef broth.
- Transfer and assemble: Pour everything into a greased 9×13 inch baking dish. Stir in 1 cup of the shredded cheese.
- Cover and bake: Cover tightly with foil and bake for 40 minutes.
- Add remaining cheese: Uncover, sprinkle on the remaining 1 cup cheese (and jalapeno slices if you want), then bake uncovered for 10 minutes until bubbly.
- Rest before serving: Let it sit for 10 minutes. This helps the rice finish soaking up the liquid and makes it easier to scoop.
That rest time is annoying when everyone is hungry, I know. But it really does make the casserole set up better. If you are looking for another busy week dinner that bakes up in one dish, this one is worth bookmarking too: easy fajita chicken casserole for busy weeknights.
How to Adjust the Spice Level
The easiest way to keep everyone happy is to build a flavorful base that is not painfully spicy, then let people customize. Here is how I do it:
Mild: Use a mild can of diced tomatoes with green chiles, skip jalapeno, and keep chili powder at 1 tablespoon. Serve with sour cream and avocado to mellow it out.
Medium: Use the recipe as written, then offer hot sauce at the table. A pepper jack cheese blend also adds a little kick.
Hot: Add jalapeno slices before baking, use hot diced tomatoes with green chiles, and add a pinch of cayenne with the spices. You can also finish your serving with pickled jalapenos.
This is one reason I make Mexican Ground Beef Casserole with Rice so often. It can be gentle or fiery depending on who is eating.
Tips for the Best Beef and Rice Casserole
A few small things make a big difference here. These are the tips I wish I knew the first time I made it.
Brown the beef properly: Let it actually brown, not just turn gray. Browning adds a deeper flavor.
Use long grain rice: It holds up well and cooks evenly. Shorter rice can get a little sticky.
Keep it covered at first: That foil is not optional. It traps steam so the rice can cook through.
Rest after baking: Ten minutes helps the casserole firm up and keeps it from being soupy.
If the rice is undercooked: Add a splash of broth, cover again, and bake 10 more minutes. Most ovens and pans behave a little differently, so do not panic.
Make Ahead, Storage and Freezing
This is the kind of meal that fits real life. You can prep it ahead, stash leftovers, and freeze portions without it turning weird.
Make ahead: Assemble everything in the baking dish, cover tightly, and refrigerate up to 24 hours. When you bake it, you may need an extra 5 to 10 minutes since it starts cold.
Fridge storage: Keep leftovers in an airtight container for up to 4 days. Reheat in the microwave with a tiny splash of broth or water so the rice stays tender.
Freezing: Cool completely, then freeze in a freezer safe container for up to 3 months. Thaw overnight in the fridge, then reheat covered in the oven at 350 F until hot.
Mexican Ground Beef Casserole with Rice is honestly one of my favorite freezer meals because it reheats like a champ.
Mexican Ground Beef Casserole Variations
I love the classic version, but here are a few easy swaps if you want to change it up.
Ground turkey or chicken: Swap in a leaner ground meat. Add a little extra oil if the pan looks dry.
Cheese variations: Cheddar for classic flavor, Monterey Jack for extra meltiness, pepper jack for heat, or a Mexican blend for convenience.
Veggie options: Add zucchini, diced poblano, or a couple handfuls of spinach stirred in right before baking.
Optional toppings: Crushed tortilla chips, cilantro, diced avocado, sliced green onions, lime wedges, sour cream, or extra jalapenos.
What to Serve With It
This is filling on its own, so I usually keep sides simple. Here are a few ideas that work well:
- A crunchy green salad with a limey dressing
- Warm tortillas or tortilla chips
- Guacamole or sliced avocado
- Pico de gallo or salsa
- Roasted peppers and onions
If you are serving a crowd, I like to set up a little topping bar so everyone can build their perfect bowl.
Frequently Asked Questions About Mexican Ground Beef Casserole
Can I use instant rice?
I would not for this one. Instant rice can turn mushy because it cooks much faster than the casserole timing. Long grain rice works best.
What if the rice is still undercooked?
Stir in a splash of broth, cover tightly with foil again, and bake 10 more minutes. Let it rest after baking so the steam finishes the job.
Can I make it on the stovetop?
You can, but you will need a large pot with a tight lid. Simmer on low until the rice is tender, stirring once or twice so it does not stick, then add cheese at the end.
Can I make it ahead?
Yes. Assemble it, cover, and refrigerate up to 24 hours. Bake as directed, adding a few extra minutes if needed.
Can I freeze it?
Yes. Cool completely, freeze up to 3 months, and thaw overnight in the fridge before reheating.
What can I use instead of black beans?
Pinto beans are the closest swap. Kidney beans work too, and even chickpeas are fine if that is what you have.
