Ingredients for French Onion Ground Beef and Rice Casserole
- 1 lb ground beef
- 1 cup long-grain white rice (uncooked)
- 1 can (10.5 oz) French onion soup
- 1 can (10.5 oz) beef consommé
- 1 cup shredded mozzarella cheese
- 1 cup shredded cheddar cheese
- 1 tablespoon butter
- Salt and pepper to taste
- Fresh parsley for garnish (optional)

Step 1: Prepare the Beef Mixture
In a large skillet over medium heat, melt the butter and add the ground beef. Cook the beef until browned and fully cooked, breaking it apart as it cooks. Season with salt and pepper to taste. Once done, drain any excess grease and set the beef aside.
Step 2: Cook the Rice
In the same skillet, add the uncooked rice. Pour in the French onion soup and beef consommé, stirring well to combine. Bring the mixture to a gentle simmer, then reduce the heat to low. Cover and let it cook for about 18-20 minutes, or until the rice is tender and has absorbed most of the liquid.
Step 3: Combine and Assemble
Preheat your oven to 375°F (190°C). In a greased casserole dish, spread the cooked ground beef evenly across the bottom. Top it with the rice mixture, spreading it out for even coverage.
Step 4: Add the Cheese
Sprinkle the shredded mozzarella and cheddar cheese generously over the top.
Step 5: Bake the Casserole
Place the casserole in the preheated oven and bake for 15-20 minutes, or until the cheese is melted, bubbly, and golden brown on top.
Step 6: Serve
Remove the casserole from the oven and let it cool for a few minutes. Garnish with fresh parsley if desired, then serve and enjoy!
