Step-by-Step Instructions
Follow these detailed instructions for a perfectly baked casserole:
- Preheat Oven:
Set your oven to 350°F (175°C) and generously grease a 9×13-inch baking dish to prevent sticking. - Cook the Beef:
Melt 2 tablespoons of butter in a large skillet over medium heat. Add 1 lb of ground beef and cook until browned and fully cooked. Drain excess fat to keep the casserole from being greasy. - Season the Meat:
Stir in 1 tsp onion powder, 1 tsp garlic powder, salt, and pepper. Make sure the beef is evenly coated with the seasoning for a well-balanced flavor. - Combine Ingredients:
In a mixing bowl, combine the cooked beef, 3 cups cooked rice, 1 can condensed French onion soup, and 1 cup sour cream. Mix until fully incorporated. - Assemble the Casserole:
Spread the beef and rice mixture evenly in the prepared baking dish. Top with 1 cup shredded mozzarella cheese for a melty, golden finish. - Bake:
Bake uncovered for 25–30 minutes until the cheese is melted and golden brown. For an extra touch of crispiness, broil the top for 2–3 minutes at the end. - Garnish & Serve:
Remove from oven and sprinkle with 1 tbsp chopped parsley before serving. Serve hot and enjoy the creamy, cheesy comfort in every bite.
Pro Tip: Use day-old rice for the best texture, as it prevents the casserole from becoming mushy.
Tips & Variations
- Cheese Alternatives: Try Gruyère, provolone, or sharp cheddar for different flavor profiles.
- Healthier Option: Swap sour cream for Greek yogurt and use lean ground turkey instead of beef.
- Vegetable Boost: Add sautéed mushrooms, bell peppers, or spinach for extra nutrients.
- Spice It Up: A pinch of paprika, cayenne, or crushed red pepper flakes can add a subtle heat.
