Ingredients
- 1 tablespoon olive oil
- 1 pound ground beef (or ground turkey for a lighter option)
- 1 small onion, finely chopped
- 3 cloves garlic, minced
- 1 cup long-grain white rice, rinsed
- 1 (14.5-ounce) can diced tomatoes with green chilies, undrained
- 1 (15-ounce) can black beans, drained and rinsed
- 1 cup frozen corn kernels
- 1 ½ cups beef broth (or chicken/vegetable broth)
- 1 teaspoon ground cumin
- 1 teaspoon chili powder
- ½ teaspoon smoked paprika
- ½ teaspoon dried oregano
- Salt and freshly ground black pepper, to taste
- 1 cup shredded Mexican blend cheese (cheddar, Monterey Jack, etc.)
- Fresh cilantro, chopped (optional, for garnish)
- 1 lime, cut into wedges (optional, for serving)
Instructions
- Heat the olive oil in a large, deep skillet or sauté pan over medium-high heat. Add the ground beef and cook, breaking it apart with a spoon, until browned and cooked through, about 5-7 minutes. Drain excess fat if necessary.
- Add the chopped onion and garlic to the skillet with the beef. Sauté for 3-4 minutes until the onion becomes translucent and fragrant.
- Stir in the rinsed rice and cook for 1-2 minutes, stirring frequently, to lightly toast the rice and coat it with the oil and beef juices.
- Add the diced tomatoes with their juices, black beans, corn, beef broth, cumin, chili powder, smoked paprika, oregano, salt, and pepper. Stir everything together to combine evenly.
- Bring the mixture to a boil, then reduce heat to low. Cover the skillet with a tight-fitting lid and simmer gently for 18-20 minutes, or until the rice is tender and has absorbed most of the liquid.
- Remove the skillet from heat and sprinkle the shredded cheese evenly over the top. Cover again and let sit for 5 minutes to allow the cheese to melt.
- Garnish with chopped fresh cilantro and serve with lime wedges on the side for squeezing over the casserole.
Tips
- Substitutions: Swap ground beef with ground turkey, chicken, or a plant-based meat alternative for a different protein. Use brown rice if preferred, but increase the simmering time to about 40-45 minutes and add extra broth as needed.
- Beans and veggies: Black beans work well, but pinto beans or kidney beans can be used instead. Feel free to add diced bell peppers or chopped jalapeños for extra flavor and heat.
- Rice texture: Avoid lifting the lid frequently while cooking, as this lets steam escape and can result in undercooked rice. If the rice is still firm after the cooking time, add a splash of broth, cover, and cook for a few more minutes.
- Cheese options: Use a Mexican cheese blend for authentic flavor, or try sharp cheddar, pepper jack, or queso fresco. For a dairy-free version, omit the cheese or use a plant-based alternative.
Serving Suggestions
This Mexican rice casserole is a complete meal on its own but pairs wonderfully with fresh sides such as a crisp green salad, sliced avocado or guacamole, and a dollop of sour cream or Greek yogurt. For added crunch, serve with tortilla chips or sprinkle crushed chips on top right before serving. A side of pickled jalapeños or a fresh tomato salsa can also brighten the dish.
Variations
You can customize this casserole to suit your taste or dietary needs. For a vegetarian version, omit the meat and add extra beans or sautéed vegetables like zucchini, mushrooms, or spinach. To make it spicier, increase the chili powder or add cayenne pepper. For a creamier texture, stir in a half cup of cream cheese or sour cream before adding the cheese topping. Another variation is to swap the white rice for quinoa or cauliflower rice for a lower-carb option, adjusting cooking times accordingly.
Storage and Reheating
Store any leftovers in an airtight container in the refrigerator for up to 3-4 days. When reheating, add a splash of broth or water to loosen the rice and cover the dish to retain moisture. Reheat gently in a skillet over medium-low heat or in the microwave until warmed through. For longer storage, freeze the casserole in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator before reheating.
Frequently Asked Questions
Can I use instant rice for this recipe?
Instant rice is not recommended because it cooks much faster and requires less liquid. This recipe depends on the rice absorbing broth slowly to develop flavor and texture. If you use instant rice, the timing and liquid amounts will need significant adjustment, which may affect the final casserole texture.
Is it necessary to rinse the rice before cooking?
Rinsing rice removes excess surface starch, which helps prevent it from becoming overly sticky or mushy. For this dish, rinsing will give you a better texture, but if you’re in a hurry, it’s not mandatory.
Can I make this recipe gluten-free?
Yes, this casserole is naturally gluten-free as long as you use gluten-free broth and canned ingredients. Always check labels on broth, canned tomatoes, and spices to confirm they do not contain gluten or cross-contamination.
How do I make this recipe spicier?
To increase heat, add diced jalapeños or serrano peppers when sautéing the onions, or increase the chili powder and add a pinch of cayenne pepper. You can also top with sliced fresh chilies or serve with spicy salsa.
Can I prepare this casserole ahead of time?
You can prepare the meat and sautéed vegetables ahead and store separately in the fridge for up to 2 days. However, it’s best to cook the rice fresh when ready to serve, as rice texture can change after refrigeration. Alternatively, fully assemble and bake the casserole, then reheat as needed.
What’s the best skillet to use?
A heavy-bottomed, oven-safe skillet with a lid works best for even cooking and heat retention. Cast iron or enameled cast iron skillets are ideal, but a deep non-stick sauté pan with a tight lid will also work well.
This one skillet Mexican rice casserole is a convenient, flavorful meal that balances protein, veggies, and carbs in a single pan. With simple ingredients and flexible options, it’s a reliable go-to for busy evenings, potlucks, or casual family dinners.
