How to Make One Pot Mexican Rice Casserole

Step 1: Sauté Aromatics

Start by heating a tablespoon of oil in a large pot over medium heat. Add diced onions and minced garlic, cooking until fragrant and translucent—this foundation unlocks deep flavor for the casserole.

Step 2: Add Vegetables and Spices

Stir in chopped bell peppers followed by the Mexican spice blend, coating the veggies to awaken those smoky, warm notes.

Step 3: Combine Rice and Liquids

Add the dry rice, canned diced tomatoes with green chilies, black beans, and broth. Stir everything together, making sure the rice is fully submerged in the liquid.

Step 4: Simmer Covered

Bring the mixture to a boil, then reduce heat to low and cover the pot. Let it simmer gently until the rice is tender and has absorbed most of the liquid, about 18 to 20 minutes.

Step 5: Add Cheese and Finish

Remove the lid and sprinkle shredded cheese over the top. Replace the cover and let it sit for 5 minutes off the heat, allowing the cheese to melt perfectly.

Pro Tips for Making One Pot Mexican Rice Casserole

• Toast the Rice: Lightly toasting the rice in the pot before adding liquids intensifies its flavor.

• Don’t Peek Too Often: Keep the lid on during simmering to trap steam and cook the rice properly.
• Use Fresh Spices: Freshly ground spices make a noticeable difference in flavor quality and aroma.
• Rest Before Serving: Let the casserole sit for a few minutes after cooking so flavors can settle and meld beautifully.
