Ingredients

1 lb (450g) ground beef
1 cup uncooked long-grain rice
1 small onion, diced
2 cloves garlic, minced
1 can (14.5 oz) diced tomatoes (with juices)
1 cup corn (fresh, canned, or frozen)
2 cups beef broth
1 cup shredded cheddar cheese (or Mexican blend)
1 tbsp olive oil
1 tsp chili powder
1/2 tsp cumin
1/2 tsp paprika
1/2 tsp oregano
Salt and pepper to taste
Fresh cilantro (for garnish)
Optional: sliced jalapeños, lime wedges

Instructions

Step 1: Sauté the Aromatics

Heat olive oil in a large skillet over medium heat. Add diced onion and cook for 3–4 minutes until softened. Stir in garlic and cook for another 30 seconds until fragrant.

Step 2: Brown the Beef

Add ground beef to the skillet. Cook until browned, breaking it up with a spoon as it cooks. Drain excess fat if needed.

Step 3: Add Seasonings

Stir in chili powder, cumin, paprika, oregano, salt, and pepper. Mix well so the beef is evenly coated with spices.

Step 4: Add Rice and Liquids

Pour in the uncooked rice, diced tomatoes (with juice), corn, and beef broth. Stir everything together until well combined.

Step 5: Simmer

Bring the mixture to a gentle boil, then reduce heat to low. Cover and simmer for 18–20 minutes, or until the rice is tender and has absorbed most of the liquid.

Step 6: Add Cheese

Sprinkle shredded cheese evenly over the top. Cover again and let it melt for 2–3 minutes until gooey and delicious.

Step 7: Garnish and Serve

Remove from heat and garnish with fresh cilantro, jalapeños, or a squeeze of lime juice. Serve warm straight from the skillet.

Tips for the Best One Pot Casserole

Use the Right Rice
Long-grain white rice works best because it cooks evenly without becoming mushy.

Don’t Skip the Lid
Covering the skillet ensures the rice cooks properly by trapping steam.

Adjust the Spice Level
Add more chili powder or jalapeños if you like heat, or reduce for a milder version.

Let It Rest
After cooking, let the dish sit for a few minutes. This helps the flavors settle and the texture firm up.

Variations to Try

1. Chicken Version

Swap ground beef for ground chicken or shredded rotisserie chicken.

2. Vegetarian Option

Replace meat with black beans or pinto beans for a hearty meat-free dish.

3. Tex-Mex Upgrade

Add bell peppers, black beans, and a dollop of sour cream on top.

4. Low-Carb Option

Use cauliflower rice instead of regular rice (adjust cooking time accordingly).

5. Extra Cheesy

Mix cheese into the rice and add more on top for a double-cheese effect.

Serving Suggestions

This dish is hearty on its own, but you can elevate your meal with:

Fresh green salad with lime dressing
Tortilla chips for scooping
Guacamole or sliced avocado
Sour cream or Greek yogurt
Warm tortillas for wrapping

Storage and Reheating

Refrigerator:
Store leftovers in an airtight container for up to 4 days.
