Ingredients for Best One-Pot Mexican Rice Casserole
Gathering the right ingredients is the first step to creating the Best One-Pot Mexican Rice Casserole. Here’s what you’ll need:
- Ground beef: I prefer 85% lean for a balance of flavor and fat. You can substitute with ground turkey or chicken for a lighter option.
- Onion: A small diced onion adds sweetness and depth. Feel free to use shallots or green onions if you have them on hand.
- Garlic: Minced garlic brings a fragrant kick. Fresh is best, but jarred garlic works in a pinch.
- Chili powder: This spice gives the casserole its signature warmth. Adjust the amount based on your spice tolerance.
- Cumin: Earthy and aromatic, cumin enhances the Mexican flavors. It’s a must-have in my spice cabinet!
- Salt and black pepper: Essential for seasoning. Always taste as you go to get it just right.
- Long-grain white rice: This is the base of the casserole. You can use brown rice, but adjust the cooking time accordingly.
- Black beans: Canned, drained, and rinsed, they add protein and fiber. You can swap them for pinto beans or kidney beans.
- Corn: Frozen or canned corn adds sweetness and texture. It’s a great way to sneak in some veggies!
- Diced tomatoes: Canned tomatoes provide moisture and flavor. I love using the ones with green chilies for an extra kick.
- Tomato sauce: This helps bind everything together. You can use salsa for a zesty twist.
- Beef broth: It adds richness. Vegetable broth works well for a vegetarian version.
- Cheddar or Mexican blend cheese: Shredded cheese on top creates a gooey, melty finish. Feel free to experiment with pepper jack for some heat!
- Cilantro: Fresh cilantro is optional but adds a burst of freshness. If you’re not a fan, skip it or use parsley instead.

How to Make Best One-Pot Mexican Rice Casserole
Now that you have all your ingredients ready, let’s dive into making the Best One-Pot Mexican Rice Casserole. This process is straightforward and fun! Follow these simple steps, and you’ll have a delicious meal in no time.
Step 1: Brown the Ground Beef
Start by heating a large skillet over medium heat. Add the ground beef and cook it until it’s nicely browned, which should take about 5–6 minutes. Remember to break it apart as it cooks. This step is crucial for flavor, so don’t rush it!
Step 2: Sauté the Vegetables
Once the beef is browned, drain any excess grease if needed. Then, stir in the diced onion and minced garlic. Cook for 2–3 minutes until the onion softens and becomes translucent. The aroma will be heavenly, and it’s the perfect time to get your family’s attention!
Step 3: Add Spices and Rice
Next, sprinkle in the chili powder, cumin, salt, and black pepper. Stir everything together to coat the beef and veggies in those vibrant spices. Now, add the uncooked long-grain white rice, mixing it well to ensure it’s evenly coated with the seasonings. This step is where the magic begins!
Step 4: Combine Remaining Ingredients
Pour in the diced tomatoes, tomato sauce, and beef broth. Then, add the black beans and corn. Stir everything together until well combined. This mixture is going to bubble and simmer beautifully, creating a comforting dish that’s hard to resist.
Step 5: Simmer and Cook
Bring the mixture to a boil, then reduce the heat to low. Cover the skillet and let it simmer for 20–25 minutes. Stir occasionally to prevent sticking. You’ll know it’s ready when the rice is fully cooked and has absorbed all those delicious flavors.
Step 6: Melt the Cheese
Finally, sprinkle the shredded cheese over the top of the casserole. Cover it again for another 2–3 minutes until the cheese melts into a gooey, cheesy layer. This is the moment you’ve been waiting for! Garnish with fresh cilantro if you like, and serve hot with your favorite toppings.

Tips for Success
