Description

This hearty casserole blends savory ground beef, creamy soups, and cheesy rice for a comforting dinner the whole family will love.


Ingredients

For the Casserole:

1 lb ground beef

1 small onion, finely chopped

1 (10.5 oz) can French onion soup

1 (10.5 oz) can cream of mushroom soup

1 cup beef broth

1 cup long-grain white rice, uncooked

1 tsp garlic powder

½ tsp black pepper

½ tsp salt

1 cup shredded mozzarella or Swiss cheese


Instructions

Preheat oven to 350°F (175°C).

Cook the beef: In a skillet over medium heat, cook ground beef with the chopped onion until browned and fully cooked. Drain excess fat if needed.

Mix ingredients: In a large bowl, combine the cooked beef mixture with French onion soup, cream of mushroom soup, beef broth, uncooked rice, garlic powder, salt, and pepper. Stir until evenly mixed.

Assemble: Pour the mixture into a greased 9×13-inch casserole dish.

Bake covered: Cover tightly with foil and bake for 45–50 minutes, or until the rice is cooked through and the liquid is mostly absorbed.

Top with cheese: Uncover the dish, sprinkle shredded cheese on top, and bake uncovered for an additional 5–10 minutes until melted and bubbly.

Serve: Let rest for 5 minutes before serving. Enjoy hot!

Notes

Use Swiss cheese for a more classic French onion flavor, or mozzarella for a milder option.

Add sautéed mushrooms or green beans for extra texture and flavor.

This casserole can be made ahead and reheated—perfect for meal prep.

Store leftovers in an airtight container for up to 3 days.
