Ingredients

• 1 lb extra-lean ground beef
• 1 medium onion, chopped
• 1 cup uncooked brown or white rice
• 2 cups low-sodium beef broth
• 1 packet (1 oz) dry French onion soup mix
• 1 cup reduced-fat shredded mozzarella or Swiss cheese
• ½ cup light sour cream or plain Greek yogurt
• Salt and black pepper, to taste
• Cooking spray

Instructions

1. Preheat Oven
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with cooking spray.

2. Cook Ground Beef
In a large skillet over medium heat, cook the ground beef and chopped onion until beef is browned and onion is soft. Drain any excess fat.

3. Mix the Base
In a large bowl, combine the cooked beef and onion with uncooked rice, beef broth, French onion soup mix, and sour cream. Mix until well combined. Season with salt and pepper to taste.

4. Assemble the Casserole
Pour the mixture into the prepared baking dish and spread evenly. Cover with foil.

5. Bake
Bake for 55–60 minutes, or until rice is tender and most of the liquid is absorbed. Remove foil, sprinkle cheese over the top, and return to the oven for another 5–10 minutes until cheese is melted and bubbly.

6. Rest and Serve
Let the casserole rest for 5 minutes before serving. Garnish with fresh parsley if desired.
