Step‑by‑Step Instructions for French Onion Ground Beef and Rice Casserole

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This temperature will ensure that your French Onion Ground Beef and Rice Casserole bakes evenly, allowing the cheese to melt beautifully and form a golden crust. Meanwhile, prepare your baking dish by greasing a 9×13-inch pan with butter or cooking spray for easy removal later.

Step 2: Sauté the Beef
In a large skillet over medium heat, melt about 2 tablespoons of butter until bubbly. Add 1 pound of ground beef, breaking it apart with a spatula. Cook for about 7-10 minutes until the beef is browned and no longer pink. As the beef cooks, keep an eye on it, stirring occasionally to ensure it browns evenly and drains any excess fat when done.

Step 3: Add Seasonings
Once the beef is browned, reduce the heat slightly and stir in 1 teaspoon of onion powder, 1 teaspoon of garlic powder, and a pinch of salt and pepper. Cook for an additional 1-2 minutes, allowing the spices to toast and deepen in flavor. This step will infuse your casserole with mouthwatering aromas, setting the stage for a delicious meal.

Step 4: Combine Ingredients
In a large bowl, mix the cooked beef with 3 cups of cooked white rice, one can of condensed French onion soup, and 1 cup of sour cream. Stir these ingredients together until well combined, making sure every grain of rice is coated in the creamy mixture. This hearty blend is the foundation of your French Onion Ground Beef and Rice Casserole.

Step 5: Transfer to Baking Dish
Spread the beef and rice mixture evenly into the prepared baking dish. Use a spatula to press it down gently, ensuring a compact layer. This will help the casserole hold together while it bakes. You’ll want to make sure the mixture is distributed evenly so every bite is flavorful and delicious.

Step 6: Top with Cheese
Sprinkle 2 cups of shredded mozzarella cheese generously over the top of your casserole. Make sure you cover the entire surface for that delicious melty experience. If you prefer a different flavor, consider using Gruyère or provolone cheese for an enticing twist.

Step 7: Bake the Casserole
Place the baking dish in your preheated oven and bake uncovered for 25-30 minutes. You’ll know it’s ready when the cheese is melted, bubbly, and golden brown. Keep an eye on it during the last few minutes to prevent over-browning. The anticipation will be worth it!

Step 8: Garnish and Serve
Once baked, remove the casserole from the oven and let it cool for a few minutes. Just before serving, sprinkle freshly chopped parsley on top for an inviting, colorful touch. This final step enhances both the flavor and appearance, making your French Onion Ground Beef and Rice Casserole ready to impress!
