How to Make Cheesy Ground Beef and Rice Mexican Casserole

Preheat the oven: 375°F (190°C). Grease a 9×13 inch baking dish with a light spray of cooking oil.
Sauté aromatics: In a large skillet, heat 1 tablespoon olive oil over medium heat. Add diced onion and cook until translucent, about 3 minutes. Stir in minced garlic and cook for another 30 seconds until fragrant.
Brown the beef: Push the onion mixture to one side of the skillet. Add the ground beef, breaking it up with a spoon. Cook until browned and no longer pink, about 5–7 minutes. Drain excess fat if needed.
Season: Sprinkle chili powder, cumin, smoked paprika, cayenne (if using), salt, and pepper over the beef. Stir to coat evenly.
Add rice and liquids: Stir in the uncooked rice, ensuring it’s well mixed with the seasoned beef. Pour in beef broth and diced tomatoes with green chilies. Bring to a gentle simmer.
Simmer: Reduce heat to low, cover the skillet, and let it cook for 15 minutes, or until the rice is tender and has absorbed most of the liquid.
Transfer to baking dish: Once the rice is cooked, pour the entire mixture into the prepared baking dish. Spread it out evenly.
Add corn and cheese: Sprinkle thawed corn kernels over the top. Then, layer the shredded cheddar, Monterey‑Jack, and mozzarella cheeses evenly across the casserole.
Bake: Place the dish in the preheated oven and bake for 15–20 minutes, or until the cheese is melted, bubbly, and lightly golden.
Finish: Remove from oven, let it rest for 5 minutes, then sprinkle chopped cilantro over the top for a fresh burst of color and flavor.
Serve: Scoop generous portions onto plates. Pair with a side of warm tortillas or a crisp green salad for a complete meal.

Tips for Best Results

Rice choice matters: Long‑grain rice stays fluffy and doesn’t clump when baked.
Don’t skip the aromatics: Onion and garlic build depth; sauté them until they’re golden.
Use a good broth: Beef broth adds richness; if you prefer a lighter taste, substitute with vegetable broth.
Cheese blend: The combination of cheddar, Monterey‑Jack, and mozzarella gives a creamy melt with a subtle tang.
Cover while simmering: Keeps the rice moist and ensures even cooking.
Adjust heat: If the casserole browns too quickly, lower the oven temperature slightly.

Variations

Chicken version: Swap ground beef for ground chicken and reduce the cooking time slightly.
Vegetarian twist: Replace beef with crumbled tofu or a plant‑based ground meat alternative; keep the rest of the ingredients unchanged.
Spicy kick: Add a diced jalapeño or a splash of hot sauce to the skillet before adding rice.
Cheese swap: Use pepper jack or a Mexican blend for a different flavor profile.
Extra veggies: Toss in diced bell peppers or spinach with the onions for added nutrition.

Storage

Let the casserole cool completely before covering it tightly with plastic wrap or foil. Store in the refrigerator for up to 4 days. Reheat individual portions in the microwave for 2–3 minutes or in a preheated oven at 350°F (175°C) for 15 minutes, until heated through.
