How to Make One Pot Mexican Rice Casserole

Step 1: Sauté the aromatics

Heat a bit of oil in a large skillet or deep pan over medium heat. Add diced onions and minced garlic, cooking until softened and fragrant—this creates the savory base for the casserole.

Step 2: Add rice and seasonings

Stir in the uncooked long-grain rice and Mexican seasoning blend. Toast the rice lightly for a couple of minutes to enhance its nutty flavor and help it absorb the spices more evenly.

Step 3: Combine remaining ingredients

Add your canned tomatoes with green chilies, black beans, corn, and chicken broth. Stir everything together, ensuring the rice is evenly submerged in liquid for even cooking.

Step 4: Simmer until rice is tender

Bring the mixture to a gentle boil, then reduce the heat to low and cover. Let it simmer for about 20-25 minutes or until the rice is fully cooked and liquid is mostly absorbed.

Step 5: Add cheese and finish baking

Sprinkle shredded cheddar cheese evenly over the top. Cover again and cook for an additional 5 minutes until the cheese melts and forms a gooey topping. Optional: place under a broiler for 2-3 minutes if you want a golden-brown crust.

Pro Tips for Making One Pot Mexican Rice Casserole

• Use fresh spices: If possible, use freshly ground cumin and chili powder for the brightest flavor.
• Don’t lift the lid: Avoid removing the cover during simmering to keep steam trapped for perfectly cooked rice.
• Adjust liquid: Depending on your rice type, you may need slightly more or less broth—check texture towards the end.
• Add lime last: Squeeze fresh lime juice after cooking to keep its zesty brightness intact.
• Let it rest: Allow the casserole to sit covered for 5 minutes after cooking to let flavors meld and rice finish steaming.
