I use fire roasted corn because I like the flavor but any corn will do.
📖 Variations
There are so many ways you can adapt this recipe to fit your family's cravings—or to satisfy picky eaters!
- Instead of ground beef, try using ground turkey, ground pork, or ground chicken.
- Before baking, add your favorite taco toppings, like green chilies, red or green peppers, black olives, or fresh tomatoes. (This is a great way to "clean out" your fridge before a big grocery haul!)
- I love a little bell pepper sauteed with the meat.
- For more spice, season with hot chili powder or sauce. You can also buy a hotter version of your favorite salsa.
- Don't forget the garnish! Here are my faves: green onions, cilantro, shredded lettuce, avocado, crushed tortilla chips, a squeeze of fresh lime juice, and, of course, a big dollop of sour cream!
- Instead of black beans, you can substitute them with kidney beans or refried beans.
- If you don't have salsa on hand, use the same measurement of plain tomato sauce or a can of Rotel tomatoes.
🔪 Instructions
This is an overview of the instructions. Full instructions are in the green recipe card at the bottom of the page.
- Saute the chopped onion. In the same pan, brown the meat and season with garlic powder and salt.
- Then, add the ground beef mixture to the prepared casserole dish.
- Mix in 1 cup of the Cheddar cheese. Add the remaining ingredients
- Bake covered with foil for 35-40 minutes. Top with more cheese and bake again until melted.
Casserole times and temps
Sometimes you need to bake two things at once - here's how to adjust the time and/or temperatures of your casserole!
These times are only an estimate. Be sure to check your casserole often. It's done when an instant-read thermometer registers 165F when stuck in the middle of the casserole.
| Temperature | Time | Time From Frozen |
| 300F | add 25 minutes | add 25 minutes and multiply by 2 |
| 325F | add 20 minutes | add 20 minutes and multiply by 2 |
| 350F | add 10 minutes | add 10 minutes and multiply by 2 |
| 375F | 30 minutes | multiply by 2 |
| 400F | subtract 5 minutes | subtract 5 minutes and multiply by 2 |
🥫 Storage
This is the ultimate Mexican casserole because it's just so versatile. You can refrigerate leftovers in an airtight container for up to three days. Simply microwave individual servings until they're heated through.
Because this casserole includes rice it freezes much better than the beefy Dorito bake recipe. If you think you're going to want to freeze it and can't decide between the two - choose this!
If you'd like, you can freeze leftovers in airtight, freeze-proof containers or bags. They'll last frozen for up to three months.
Let the frozen Mexican Ground Beef Casserole thaw first in the refrigerator for a day or skip straight to the microwave! (Hint: if you flatten the freezer bags before freezing, they'll thaw more evenly and quickly!)
Alternatively, to reheat a larger portion, place the leftovers into an oven-proof dish and bake at 350°F until thawed and warm throughout. See, I don't call this the best Mexican beef casserole ever for nothing!
💭 Things to know
Expert Tip: Before adding the beef to the baking dish, be sure to drain it well so your casserole isn't oily. However, don't put beef fat down your sink! Instead, line a drinking glass with a plastic bag or foil and pour the grease in, letting it cool before sealing and discarding it in the trash.
- Carefully drain your beans and corn before adding them to the dish. A little residual moisture is fine, but too much liquid can turn your Mexican casserole into soup!
- Use lean (90/10) ground beef for best results and less need to drain the fat.
- Don't pre-cook the Minute rice before adding it to the casserole. During the baking process, it will soak up the liquid and cook to al dente perfection.
👩🍳 FAQs
Absolutely! Prepare the meat mixture and other ingredients as directed. Then, pour it all into a disposable foil baking dish and wrap it tightly with plastic or foil.
Store in the refrigerator for up to three days, and bake as directed. You can also store it in the freezer for up to three months. However, to bake from frozen, add 45 minutes to an hour of bake time.
Yes, you'll need to cook the rice ahead if time, though.
