Ingredients

• 1 lb ground beef (or ground turkey for a leaner option)
• 2 bell peppers (any color), diced
• 1 medium onion, diced
• 3 cloves garlic, minced
• 2 cups cooked white or brown rice
• 1 14.5 oz can canned diced tomatoes (with juice)
• 1 8 oz can canned tomato sauce
• 1.5 cups shredded cheddar cheese
• 1 tsp Italian seasoning
• 1 tsp paprika
• 0.5 tsp salt
• 0.5 tsp black pepper
• 1 tbsp olive oil
• 2 tbsp fresh parsley, chopped (optional, for garnish)

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Heat olive oil in a large skillet over medium heat. Add the ground beef and cook, breaking it apart with a spoon, until browned and fully cooked (about 5-7 minutes). Drain off any excess grease.

Step 3

Add the diced onion, diced bell peppers, and minced garlic to the skillet. Cook for 5-7 minutes, stirring occasionally, until the vegetables are softened.

Step 4

Stir in the Italian seasoning, paprika, salt, and black pepper. Cook for 1-2 minutes to let the spices bloom.

Step 5

Reduce the heat to low and add the canned diced tomatoes (with juice), tomato sauce, and cooked rice. Stir to combine everything thoroughly. Let the mixture simmer gently for 5 minutes.

Step 6

Transfer the mixture to a greased 9x13-inch baking dish. Spread it out evenly.

Step 7

Sprinkle the shredded cheddar cheese evenly over the top of the casserole.

Step 8

Bake in the preheated oven for 20 minutes, or until the cheese is melted and bubbly.

Step 9

Remove from the oven and let the casserole rest for 5 minutes before serving.

Step 10

Garnish with chopped fresh parsley, if desired, and serve hot.
