Mexican Ground Beef Casserole with Rice Recipe FAQs
What kind of ground beef should I use for the casserole?
Absolutely! I recommend using lean ground beef (80/20) as it gives you a nice balance of flavor without excessive grease. If you’re looking for a healthier option, you can also use ground turkey or chicken, but be sure to adjust seasoning as they have milder flavors.
How should I store leftovers of the Mexican Ground Beef Casserole with Rice?
After enjoying your delicious casserole, store any leftovers in an airtight container in the fridge. It should stay fresh for about 3 days. Just make sure it’s completely cooled before sealing to avoid condensation—nobody wants a soggy casserole!

Then, portion it into individual serving sizes and place them in resealable freezer bags or airtight containers. It will keep for up to 3 months. Don’t forget to label your bags with the date to keep track of freshness!
What if my rice doesn't cook properly in the casserole?
If you find your rice is undercooked after baking and there’s still too much liquid, it may need a bit more time. Cover the casserole with foil again and continue baking in 10-minute increments until the rice is tender. Keep an eye on the liquid levels as well; if too much has evaporated, you can add a splash of broth or water to help it along.
Are there any dietary considerations I should keep in mind?
Yes! While this casserole is naturally gluten-free if you ensure your taco seasoning and any additional toppings are gluten-free, it does contain dairy from the cheese. If you have lactose intolerance, you can easily substitute with lactose-free cheese. Always check for any allergies related to the canned ingredients like beans or corn before serving.
What toppings can I add to this casserole?
The more the merrier! This dish is versatile, so feel free to personalize it to your liking. Consider topping it with diced avocados, sour cream, or fresh cilantro after baking.
