🥘 Ingredients

This Mexican rice recipe uses many pantry staples you probably already have on hand! Conveniently grab all of the fresh ingredients that you’ll need at your local grocery store. See the recipe card at the bottom of the post for nutritional information.

• Olive Oil: Use extra virgin olive oil to saute the vegetables, bringing out their flavors and tenderness.
• Red Onion & Garlic: Chopped onion and minced garlic are a must in this Mexican skillet casserole!
• Bell Pepper & Corn Kernels: Diced red and yellow bell peppers add flavor and boost the nutritional value of this tasty casserole. Frozen corn is a convenient addition for extra fiber and texture.
• Black Beans: Black beans add extra protein to this easy Mexican rice bake.
• Taco Seasoning & Jalapeno: Using a premade taco seasoning will save you time and load this dish with tex-mex flavor. Add a bit of spice with deseeded and chopped jalapeno peppers!
• White Rice: I prefer white rice for this Mexican meal, which has a great texture and absorbs the flavor of the seasoning perfectly.
• Diced Tomatoes: Use the whole can of diced tomatoes so the rice can absorb the sauce!
• Vegetable Broth: Vegetable broth will give the rice extra flavor, opposed to using water.
• Mexican Blend Cheese: This cheesy Mexican rice casserole uses Mexican cheese blended within the dish and top of it for extra gooey texture.

🍲 Ingredient Substitutions

• Oil: Use any high-heat oil that you prefer for sauteing the vegetables.
• Veggies: Try orange or green bell peppers, mushrooms, zucchini, or carrots in this rice and bean casserole.
• Beans: Pinto beans or refried beans are also tasty options for this Mexican rice bake.
• Spices: Make your own blend of spices using chili powder, cumin, garlic powder, onion powder, paprika, oregano, and cayenne.
• Rice: Brown rice can be used instead of white rice for more whole grains, but you might need to adjust the baking time as brown rice takes longer to cook. You can also use long grain basmati rice if you prefer. Or, for a fun twist, try using my rice cooker cilantro lime rice for even more flavor!
• Tomatoes: Tomato sauce or tomato paste can be used instead of diced tomatoes. Just be sure to add in some additional liquid if you use paste.
• Broth: Use chicken broth or beef broth in place of the vegetable broth if you do not need this recipe to be vegetarian or vegan.

🔪 How To Make Mexican Rice Casserole

Making a Mexican casserole with rice and beans is super easy! It is the ultimate lunch or dinner recipe for anyone who likes a dish with plenty of flavor but minimal effort. Here is how to make this recipe for Mexican rice casserole:

Preheat Oven, Saute Onions & Garlic: The first step to make this Mexican rice skillet is to preheat the oven to 350 degrees F / 180 C. Then, heat the oil over a medium heat in a large skillet. Sauté the onion and garlic for 2-3 minutes, until translucent.

Add Ingredients: Remove from the heat and add all ingredients from red bell peppers to vegetable broth. Stir to combine.

Mix In Cheese: Pour the rice mixture into a baking dish and stir through ½ cup of cheese.

Bake, Add Cheese Layer: Cover with aluminum foil and bake for 50 minutes. Test to ensure the rice has cooked through. When the rice is soft, remove the foil, top with remaining cheese and continue to bake for another 10 minutes until the cheese melts.

Serve: Serve topped with sliced jalapeno peppers, chopped cilantro, a squeeze of lime juice and a dollop of sour cream.

💭 Expert Tips

• Tender Rice: Test the rice to make sure it is cooked through. If after 50 minutes the rice is still a little firm, cover with foil and cook for another 10 minutes.
• Allow Cool Time: Allow the black bean and rice casserole to sit for 5 minutes before serving with your favorite Mexican toppings and sides.
• One Pot Casserole: Make this a one pot Mexican rice casserole by sauteing the veggies in a cast iron skillet, which can then directly be transferred over into the oven! Easy clean up and minimal effort.
