Ingredients

Scale 1x2x3x

Main Ingredients

• 1 lb ground beef
• 3 cups cooked white rice
• 1 can (10.5 oz) condensed French onion soup
• 1 cup sour cream
• 2 cups shredded mozzarella cheese
• 2 tbsp butter

Seasonings

• 1 tsp onion powder
• 1 tsp garlic powder
• Salt, to taste
• Black pepper, to taste

Garnish

• 1 tbsp chopped parsley (optional)

Instructions

1. Cook the ground beef: In a large skillet, melt butter over medium heat. Add the ground beef and cook until browned, breaking it apart with a spatula as it cooks. Once browned, drain excess fat from the skillet to reduce greasiness.
2. Season the beef: Stir in onion powder, garlic powder, salt, and pepper into the cooked ground beef. Mix well to ensure the seasonings are evenly distributed and fragrant.
3. Combine casserole mixture: In a large bowl, mix the seasoned ground beef, cooked white rice, condensed French onion soup, and sour cream until all ingredients are thoroughly combined into a creamy mixture.
4. Prepare the baking dish and oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or cooking spray to prevent sticking.
5. Assemble the casserole: Spread the beef and rice mixture evenly into the prepared baking dish. Sprinkle the shredded mozzarella cheese evenly over the top of the mixture to create a cheesy crust when baked.
6. Bake the casserole: Place the baking dish in the preheated oven and bake uncovered for 25 to 30 minutes, or until the cheese has melted completely and is bubbly with golden edges.
7. Garnish and serve: Once baked, remove the casserole from the oven and let it sit for a few minutes. Garnish with chopped parsley, if desired, before serving hot to enjoy the comforting flavors at their best.

Notes

• You can substitute ground beef with ground turkey or chicken for a leaner option.
• Use brown rice instead of white rice for added fiber and nutrients.
• If you prefer a stronger onion flavor, add caramelized onions to the mixture.
• For a gluten-free option, verify that the condensed French onion soup is gluten-free or prepare a homemade version.
• Leftovers can be refrigerated for up to 3 days and reheated in the oven or microwave.
