How to Make One Pot Mexican Rice Casserole

Step 1: Sauté Aromatics and Meat

Start by heating oil in a large pot over medium heat. Add diced onion and garlic, cooking until soft and fragrant. Then, add your ground meat or beans, breaking it apart and cooking thoroughly until the meat is browned or beans heated through.

Step 2: Add Vegetables and Spices

Stir in diced bell peppers, corn, and your carefully measured spices. Cooking the spices briefly unlocks their essential oils, intensifying their flavors and evenly coating the veggies and meat.

Step 3: Combine Rice and Liquids

Pour in the rice, making sure it’s evenly mixed, followed by the diced tomatoes and chicken broth. Give everything a good stir to combine all ingredients well, then cover the pot with a lid.

Step 4: Simmer Until Rice is Tender

Reduce heat to low and let the casserole simmer for about 20 minutes, or until the rice has absorbed the liquid and is tender. Avoid lifting the lid too often to keep the steam trapped and the rice perfectly cooked.

Step 5: Add Cheese and Finish

Once the rice is cooked, sprinkle the shredded cheese over the top, cover, and let it melt for five minutes. Garnish with fresh cilantro and a squeeze of lime juice to add brightness and a burst of fresh flavor.

Pro Tips for Making One Pot Mexican Rice Casserole

• Rice Selection: Use long-grain white rice for fluffy texture, or choose brown rice if you want chewier grains and extra nutrients.

• Use Fresh Lime: Adding lime juice just before serving enhances all the other flavors and adds vibrant zest.
• Cover Tightly: Keep the pot covered while simmering to ensure rice cooks evenly and stays moist.
• Leftover Magic: This casserole tastes even better the next day once the flavors meld, so don’t hesitate to make extra.
