FAQs
Do you cook the rice before adding it to the Mexican rice casserole?
Yes, the rice should be cooked before adding it to the Mexican rice casserole. Using pre-cooked or day-old rice helps the grains stay fluffy and absorb the flavors of the beef, beans, and seasoning without turning mushy.
How do you keep Mexican rice casserole from drying out?
To keep the casserole from drying out, mix in sour cream or a little extra broth before baking. Covering the dish with foil during the first half of baking also helps retain moisture, while uncovering at the end ensures a golden, cheesy top.
Can Mexican rice casserole be made ahead of time?
Yes, you can assemble the Mexican rice casserole up to 24 hours in advance. Store it covered in the refrigerator, then bake just before serving. If baking straight from the fridge, add an extra 10 minutes to the cooking time.
What cheese works best for Mexican rice casserole?
Cheddar, Monterey Jack, or a Mexican cheese blend works best for this casserole. These cheeses melt smoothly and provide a gooey, flavorful topping that complements the Tex-Mex flavors.
