Ingredients
  

For the Casserole:

  • 1 tablespoon olive oil
  • 1 pound ground beef or turkey, chicken, pork, sausage, or tofu
  • 1 medium onion chopped
  • 2 bell peppers any color – green, yellow, red, or orange, chopped
  • 1 jalapeño pepper chopped (optional, for a spicy kick)
  • 5 cloves garlic chopped
  • 14.5 ounces fire-roasted tomatoes or diced tomatoes or tomato sauce
  • 2 tablespoons Worcestershire sauce
  • 1 tablespoon paprika
  • 1 teaspoon dried oregano
  • 1 teaspoon dried basil
  • Salt and pepper to taste

For the Rice and Cheese:

  • 1 cup cooked rice white, brown, or wild rice
  • 1 cup shredded cheese cheddar, mozzarella, or pepper jack for extra spice

For Garnish:

  • Fresh chopped parsley
  • Red pepper flakes optional

Instructions
 

  • Prepare the Base : Preheat your oven to 375°F (190°C) if baking. Heat the olive oil in a large skillet or Dutch oven over medium heat.
  • Cook the Protein : Add the ground beef (or your preferred protein) to the skillet. Cook, breaking it into crumbles, until browned and fully cooked. Drain excess fat if necessary.
  • Sauté the Vegetables : Add the chopped onion, bell peppers, and jalapeño (if using) to the skillet. Cook for 5-6 minutes, stirring occasionally, until softened. Stir in the garlic and cook for an additional minute.
  • Build the Sauce : Mix in the fire-roasted tomatoes, Worcestershire sauce, paprika, oregano, basil, and a pinch of salt and pepper. Simmer for 5 minutes to allow the flavors to meld.
  • Combine with Rice : Stir the cooked rice into the skillet, ensuring everything is evenly combined. Taste and adjust the seasoning with salt and pepper if needed.
  • Add Cheese and Bake (Optional) : If baking, transfer the mixture to a greased casserole dish. Sprinkle the shredded cheese evenly over the top and bake for 15-20 minutes, or until the cheese is melted and bubbly. If skipping the oven, simply sprinkle the cheese over the skillet and cover until the cheese melts.
  • Garnish and Serve : Top with fresh parsley and a sprinkle of red pepper flakes if desired. Serve hot and enjoy!
