Ingredients
For the Casserole:
-
1 pound ground beef
-
2 bell peppers, chopped
-
1 onion, finely chopped
-
3 cloves garlic, minced
-
1 tablespoon Worcestershire sauce
-
1 (15 oz) can low-sodium beef broth
-
1 (15 oz) can diced tomatoes
-
1 cup uncooked long-grain white rice
-
1 tablespoon Italian seasoning
-
1 teaspoon salt
-
1/2 teaspoon black pepper
For the Topping:
-
3/4 cup shredded mozzarella cheese
-
3/4 cup shredded cheddar cheese
Step-by-Step Instructions
1. Cook the Beef & Veggies
In a large skillet, cook the ground beef over medium heat, breaking it apart as it browns. When it’s almost fully cooked, add the onions and bell peppers. Sauté for 5–10 minutes until the vegetables begin to soften.
2. Add Garlic & Aromatics
Stir in the minced garlic and cook for 1–2 minutes until fragrant.
3. Build the Casserole Base
Add the Worcestershire sauce, beef broth, diced tomatoes, rice, Italian seasoning, salt, and black pepper. Stir well to combine.
4. Simmer to Perfection
Bring the mixture to a boil, then cover and reduce the heat to low. Simmer for 20 minutes, stirring halfway through, until the rice is tender and has absorbed the flavors.
5. Add the Cheese
Once the rice is cooked, stir in half of the shredded mozzarella and cheddar until melted and incorporated. Sprinkle the remaining cheese on top, cover again, and let it melt.
💡 Quick tip: If your skillet is oven-safe, you can pop it under the broiler for 1–2 minutes to get a bubbly, golden cheese topping.
6. Serve & Enjoy
Remove from the heat and serve immediately. Garnish with fresh parsley for a pop of color if desired.
