- Cheesy Ground Beef and Rice Mexican Casserole Recipe
The most popular recipe on our site is my mom’s Busy Day Casserole, now known as our Cheesy Ground Beef and Rice Casserole. It’s a classic family-friendly recipe and a longtime favorite for picky eaters.
Because I grew up on it, I’ll always love the original, but that didn’t stop me from creating a new version. This Cheesy Ground Beef and Rice Mexican Casserole brings bold flavors while keeping everything we love about the classic. It may not replace the original for me, but it just might earn its own spot as a new family favorite.
Ingredients for Ground Beef and Rice Casserole
The ingredient list for this easy Mexican casserole is pretty short! It is one of the many reasons why we love this recipe! Here’s what you’ll need to make this Mexican Ground Beef and Rice Casserole:
- Canned Fiesta Nacho Cheese Soup: creates a creamy, cheesy base for the casserole
- Long Grain White Rice: Basmati or Jasmine rice works great here! It absorbs flavor while keeping the dish hearty and filling
- Water: helps the rice cook and soften
- Black Beans: add texture and extra protein
- Ground Beef: brings savory, satisfying flavor
- Taco Seasoning: adds classic Tex-Mex spices
- Cheddar Cheese Slices: melt over the top for a cheesy finish
- Salsa and Avocado: fresh, flavorful toppings for serving
Do I Have to Use Canned Soup?
We usually prefer cooking from scratch, but sometimes a quick and easy dinner just makes sense. This is one of those recipes where canned fiesta nacho cheese soup is the simplest option and works really well. You could make a homemade version (See our recipe in our Cheesy Ground Beef and Rice Casserole), but by the time you add the cheese, spices, and peppers needed to match the flavor, the condensed soup is often easier. If you do try it from scratch, we’d love to hear how it turned out in the comments.
Substitutions and Variations
This recipe uses simple ingredients, but it’s easy to make it your own. Add smoked paprika or canned chipotles for a smoky kick. You can also swap the ground beef for ground chicken or ground turkey.
You can finish it with a dollop of sour cream, jalapenos, or chopped green onions, switch the cheese to shredded mozzarella or pepper jack cheese, or add extra veggies like onions, tomatoes, bell peppers, or mushrooms for more texture and flavor.
Choosing the Right Ground Beef
Ground beef with a little more fat tends to have the best flavor, but this recipe is flexible and works with several options. 73% lean ground beef is the most flavorful and juicy, though it does release more fat and it will need to be drained. 80/20 ground beef is our favorite balance of flavor and moisture and what we use most often. Ground sirloin (85% lean) is a slightly leaner option that’s still tender and flavorful, while 90% lean ground beef is the leanest choice and works well here thanks to the moisture from the casserole. Any of these options will work, so use what fits your taste or what you have on hand.
How to Make Cheesy Ground Beef Rice Casserole
This taco rice casserole requires just 10 minutes of hands-on prep work, and then it’s ready to go into the oven! Here’s the basic rundown of how we make this Mexican casserole at home:
- Brown: Cook the ground beef in a skillet until browned, then drain off any excess fat.
- Season: Stir in the taco seasoning and the water called for on the packet.
- Mix: Combine the seasoned beef with the nacho cheese soup, remaining water, black beans, and rice, and mix well so everything is evenly distributed.
- Bake: Transfer the mixture to a greased 8×9-inch baking dish and bake until the rice is tender and the casserole is set.
- Top: Add your cheddar cheese slices and return to the oven just long enough for the cheese to melt.

Casserole FAQs
Yep! The rice does not need to be cooked ahead of time and using minute rice is a big no-no. Just stir the uncooked rice into everything and it will all cook evenly.
To make this Mexican ground beef casserole in an Instant Pot, brown the ground beef and drain using the sauté mode. Drain the fat and proceed like normal. Turn the Instant Pot to manual high pressure and place the lid on to cook for 5-8 minutes. You’re all set! Top with cheese at the end.
If you cook the casserole for the full 90 minutes and follow the recipe using the correct rice and liquid amounts, it should not be undercooked. One common issue is measuring liquids incorrectly. Always measure liquid ingredients in a glass measuring cup, not a dry measuring cup, which can throw off the ratios.
This recipe has been made for many years, and the only time it comes out dry is when it isn’t cooked long enough or the ingredients weren’t measured correctly. When prepared as written, there is plenty of liquid to keep the casserole moist.
Make Ahead and Storage Instructions
This Mexican casserole is easy to make ahead and store. Once cooked, leftovers can be kept in an airtight container in the refrigerator for up to 4 days. You can also freeze the fully cooked casserole for later. Freeze it directly in the pan, wrapped tightly with plastic wrap and foil, for up to 1 month.
For best results, wait to add the cheese until reheating and serving. If freezing leftovers, be sure to fully thaw the casserole in the refrigerator, then reheat it in the oven until warmed through and set.
What to Serve with Ground Beef and Rice Casserole
Looking for sides to serve with this cheesy Mexican casserole? Fresh, flavorful salads make the perfect pairing. Some of our favorites include Elote Grilled Mexican Corn Salad, Our Best Broccoli Salad, Garden Balsamic Avocado Salad, and Grilled Corn, Avocado, and Tomato Salad.
This simple casserole comes together with just 10 minutes of prep, but still delivers big, bold flavor. It’s great for weeknights, and also perfect for feeding a crowd. Plus, it freezes well, making it a great option to prepare ahead and enjoy later when you need a no-fuss meal.

Best thing we’ve head for supper in a long time. I cooked my ground beef and added the taco mix the day before. Finished assembly and baked today. It was Soo good and a big hug with children too!
That’s when we know it’s a winner…when the kids eat it! Thank you for taking time to leave a comment!
If freezing this recipe, how do you heat it to serve?
Thank you!
There is a section in the post with some tips for freezing and reheating. Make sure you defrost it in the refrigerator completely and then you can warm it up in the oven…300 degrees for about 20 minutes should do the trick!
My whole family loved it! Improvised a little. I added onions and garlic to the hamburger. I couldn’t find the right cheese soup so I used cheddar cheese soup and added finely chopped green jalapeno peppers. Will definitely make it again!
I love your improvising! Thank you so much for the feedback Jessica! So happy your family enjoyed it!
I made this taco beef rice casserole. Was super easy to put together. It smelled great baking and tasted just as good. I put the cheese on top when the cook time was 10 minutes remaining. I added the corn just to add veggies. It helped amp up the Mexican flavor. We are going to try adding jalapeños the next time to amp up the heat. (We like spice). I chunked up an avocado for garnish. The creaminess of the avocado and the tartness from the lemon juice I squeezed over it rounded out the dish. If you have big eaters I would either double the recipe, or have a salad with it.
Thank you for the great feedback!! So glad you enjoyed it!

We have 2 people in the family who can not have rice for medical reasons-can cauliflower rice be substituted?
This is such a great question! I honestly have never tried it, so I can’t answer with any confidence on this one. I don’t think it would hold up well for the 90 minute bake time, so maybe a shorter bake time would work. I would have to do some trial an error. I would just worry about the text turning out correctly. Sorry I can’t be more help!
Do I cover with foil or just bake it uncovered
Bake uncovered. Enjoy!
Has anyone doubled this recipe for a larger family? I’m wondering if cook time is still 90 minutes?
Yes, it can totally be double. Put it in a 9×13 pan and cook time stays the same.
Made this last night. Added some.chorizo and a can of corn. I can no longer get the fiesta.cheese soup ao used a jar of Tostito’s queso con salsa. Paired it woth corn pudding. Family loved it. First meal in a long time with no leftovers!
Chris!! You made our day! Adding chorizo…that is a genius idea! And I’ll have to try it with the Tostito’s queso con salsa. I bet that is equally delicious!
When we made it our first time it was actually a little on the bland side, at least for my hot sauce devouring husband. Any ideas on how to spice it up??
You could add some jalapenos, either fresh or canned, use pepper jack cheese, add a can of well-drained Rotel, or if you want more flavor but not as much heat, you could add a can of green chiles.
