Ingredients
  

For the casserole

  • 1 tablespoon olive oil for cooking
  • 1.5 pounds lean ground beef
  • 0.5 cup onion, diced
  • 1 cup diced red bell pepper (about 1 whole pepper)
  • 1 cup diced green bell pepper (about 1 whole pepper)
  • 1 cup diced orange bell pepper (about 1 whole pepper)
  • 2 teaspoons minced garlic
  • 1 tablespoon Worcestershire sauce
  • 0.75 teaspoon salt
  • 0.25 teaspoon ground black pepper
  • 0.5 teaspoon paprika
  • 2 teaspoons Italian seasoning
  • 1 14.5-ounce can diced tomatoes (undrained)
  • 1 cup uncooked long grain white rice
  • 1.5 cups beef broth
  • 1 8-ounce can tomato sauce
  • 1.5 cups shredded Colby Jack cheese (shredded and divided)
  • Fresh parsley (for garnish)

Instructions
 

Preparation

  • Preheat the oven to 375°F (190°C). Spray a 9 x 13-inch casserole dish with nonstick cooking spray and set aside.
  • In a large skillet, heat olive oil over medium-high heat. Add ground beef and cook until browned, about 7-10 minutes.
  • Add diced red, green, and orange bell peppers along with diced onion to the skillet. Cook for about 5 minutes until the vegetables soften.
  • Stir in minced garlic, Worcestershire sauce, salt, black pepper, paprika, and Italian seasoning.
  • Add diced tomatoes with juice, beef broth, tomato sauce, and uncooked rice. Mix in 1 cup of shredded Colby Jack cheese, reserving the remaining ½ cup for topping.

Baking

  • Pour the mixture into the prepared casserole dish. Top with the reserved cheese, cover with aluminum foil, and bake for 45 minutes.
  • Check if the rice is tender and the liquid has been absorbed.
  • Garnish with fresh parsley before serving.

Notes

For extra flavor, consider using ground turkey or chicken instead of beef. Customize the vegetables based on preferences. For a spicier kick, add crushed red pepper flakes or jalapeños. Store leftovers in an airtight container in the refrigerator for about 3-4 days, or freeze for up to 3 months.
