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:

  1. Brown: Cook the ground beef in a skillet until browned, then drain off any excess fat.
  2. Season: Stir in the taco seasoning and the water called for on the packet.
  3. Mix: Combine the seasoned beef with the nacho cheese soup, remaining water, black beans, and rice, and mix well so everything is evenly distributed.
  4. Bake: Transfer the mixture to a greased 8×9-inch baking dish and bake until the rice is tender and the casserole is set.
  5. Top: Add your cheddar cheese slices and return to the oven just long enough for the cheese to melt.

Casserole FAQs

Will the Rice Cook in the Casserole?

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.

Can I Make Mexican Casserole in an Instant Pot?

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.

Why did my casserole come out like soup?

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.

Why did my casserole come out dry?

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.

    Hi, any idea of how to turn this into a crockpot recipe?
    Gotta love crockpots

    1. Sweet Basil says:

      That is a great question! I don’t see why it wouldn’t work, but I haven’t tested it at all.

  2. Jacob says:

    This maybe a stupid question, but does the rice have to be cooked before it goes into the casserole, or just it is?

    1. Sweet Basil says:

      Nope, uncooked! So easy!

      1. Jacob says:

        Thank you, much appreciated.

  3. Sarah says:

    I sauteed an onion and garlic just before browning the beef. It added a bit more flavor. My husband really liked this dish. We will make it again for sure!

    1. Sweet Basil says:

      So glad you enjoyed it! Thanks for taking time to leave a comment!

  4. Mike G says:

    I couldn’t find the specific soup the recipe called for and I toyed with the idea of using Campbell’s cheddar cheese soup and mixing it with well-drained Rotel tomatoes and green chilies. I ended up opting for some ready to use nacho cheese sauce made by La Preferida (15oz). Turned out really good. Also, not all ovens are made equally so keep an eye out on the casserole. If it begins to brown too much you might want to cover it in foil for the last little bit of cooking or adjust your oven temp down a bit.

    1. Sweet Basil says:

      Thanks Mike! That is great information if the soup is hard to find. So glad it turned out well!

    2. Mike G says:

      Second time sround I scattered some sliced pickled jalapenos across the top before putting it into the oven. Came out really good. Look great and tasted a great.

  5. Elizabeth says:

    May I substitute noodles for the rice?

  6. BaseballMom says:

    Looks delicious! I’d like to double the recipe to make sure there are leftovers.  If I double all of the ingredients does the cook time stay the same? Thank you! 🙂

  7. Jane says:

    Do you cover the Mexican cheesy casserole with rice while cooking

    1. Sweet Basil says:

      No, leave it uncovered!

  8. Robyn says:

    I am confused by the ‘add water as per package instructions’.  Which package?  Is this in addition to the 2 cups you add with the soup and rice?

  9. Linda says:

    I’m confused about the amount of water.  Do you add the 2 cups plus the water specified on the taco packet?
    The recipe ingredient list states 2 cups of water, then states “Water, per packet instructions.”  The directions also state adding water twice.

    1. Sweet Basil says:

      Hi Linda, you will need an extra amount of water in addition to the 2 cups. The amount can differ per package of seasoning so check the packet, then add that amount with the seasoning to the meat. The 2 cups of water gets stirred into the rice.

      1. Isaac says:

        Hello I have had a question, I followed the directions exactly to a t and it came out burnt the first time and I took it out early the second time to save it a little, and it was dry, but how big of a can of fiesta cheese soup are u using and I figured out reading the comment I, I thought the 2 cups of water was also including the season pack which ask for 3/4 cup of water.

      2. Sweet Basil says:

        Hi Isaac! You brown the meat and add the seasoning packet and the amount of water called for on the packet instructions and let it simmer and thicken. So the meat is completely cooked and seasoned. Then you mix everything together (the soup is an 11oz can) including an additional 2 cups of water and bake for 90 minutes. Does that make sense?

  10. Erika says:

    Hi. Do you bake this uncovered or does it need to be covered with foil?

    1. Sweet Basil says:

      Uncovered.
