  • 2 cloves garlic, minced

  • 1 1/2 cups cooked rice (white, brown, or cauliflower rice for a low-carb option)

  • 1 can (14.5 oz) diced tomatoes (with juices)

  • 1 can (8 oz) tomato sauce

  • 1 tablespoon Worcestershire sauce

  • 1 1/2 teaspoons Italian seasoning

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

1. Cook the ground beef:

  • Preheat your oven to 375°F (190°C).

  • In a large skillet, heat a tablespoon of olive oil over medium heat. Add the ground beef and cook until browned, breaking it up with a spoon as it cooks (about 5-7 minutes). Once browned, drain excess fat if necessary.

2. Add the aromatics:

  • Add the chopped onion and minced garlic to the skillet with the beef and cook for 3-4 minutes, until the onion becomes soft and fragrant.

3. Combine the ingredients:

  • Stir in the diced tomatoes (with juices), tomato sauce, Worcestershire sauce, Italian seasoning, paprika, salt, and pepper. Let the mixture simmer for about 5 minutes, allowing the flavors to combine and the sauce to thicken slightly.

4. Add the rice and peppers:

  • Stir in the cooked rice and chopped bell peppers, making sure everything is well combined. Cook for another 3-4 minutes until the peppers begin to soften.

5. Assemble the casserole:

  • Transfer the beef and vegetable mixture into a greased 9×13-inch baking dish, spreading it out evenly. Sprinkle the shredded cheddar cheese on top of the casserole.

6. Bake the casserole:

  • Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly and the peppers are tender.

7. Serve:

  • Let the casserole cool for a few minutes before serving. Garnish with fresh herbs like parsley or basil, if desired, and serve warm.

Variations

  • Low-Carb Version: Swap the rice for cauliflower rice to make it a low-carb dish. This will still give you the texture of rice but with fewer carbs.

  • Add More Veggies: You can add other veggies like zucchini, mushrooms, or even corn to the casserole for added texture and flavor.

  • Spicy Version: Add a diced jalapeño or a pinch of red pepper flakes to the beef mixture for a spicy kick.

  • Ground Turkey or Chicken: For a lighter version, you can use ground turkey or ground chicken instead of beef.

  • Vegetarian Version: Use lentils or black beans in place of the ground beef for a vegetarian alternative. You can also add extra veggies like spinach or diced carrots.

Storage/Reheating

  • Storage: Store leftover casserole in an airtight container in the refrigerator for up to 3 days.

  • Reheating: Reheat in the microwave or in a 350°F (175°C) oven for about 10-15 minutes, or until heated through.

FAQs

Can I use instant rice for this recipe?

While you can use instant rice in a pinch, it’s best to use cooked rice (either freshly cooked or leftovers) for the best texture and consistency in the casserole.

Can I freeze this casserole?

Yes, you can freeze the casserole. Let it cool completely, then cover it tightly with plastic wrap and aluminum foil. Freeze for up to 3 months. To reheat, bake it directly from frozen at 375°F (190°C) for about 45 minutes, or until heated through.

Can I make this casserole ahead of time?

Absolutely! You can use mozzarella, Monterey Jack, or any other cheese you prefer. You can also mix and match cheeses for a more complex flavor.

The casserole is done when the cheese is melted, bubbly, and lightly golden brown. The peppers should be tender but still have a slight bite to them.
