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

Step 1: Brown the Beef
In a large skillet over medium heat, melt 2 tablespoons of butter. Add 1 pound of lean ground beef and cook for about 6-8 minutes, breaking it apart with a spatula until it’s browned and no longer pink. Drain any excess fat to keep your French Onion Ground Beef and Rice Casserole from becoming greasy.

Step 2: Season the Beef
Once the beef is browned, sprinkle in 1 teaspoon each of onion powder and garlic powder, along with salt and pepper to taste. Stir well to evenly coat the meat in the savory spices. This step enhances the flavor, ensuring a deliciously aromatic base for the casserole.

Step 3: Combine Ingredients
In a large mixing bowl, combine the cooked beef mixture with 3 cups of day-old cooked white rice, 1 can of condensed French onion soup, and 1 cup of sour cream. Stir until everything is fully mixed and the creamy sauce clings to the rice and beef. This mixture forms the hearty filling of your casserole.

Step 4: Preheat the Oven
While you’re mixing, preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray or a little butter to prevent sticking. A well-prepared dish allows your French Onion Ground Beef and Rice Casserole to bake evenly and come out easily once cooked.

Step 5: Assemble the Casserole
Transfer the beef and rice mixture into the greased baking dish, spreading it out evenly. Make sure it’s nicely packed for consistent cooking. Then, generously top the casserole with 2 cups of shredded mozzarella cheese, allowing for a rich, bubbling crust when cooked.

Step 6: Bake the Casserole
Place the casserole in the preheated oven and bake uncovered for 25-30 minutes, or until the cheese is melted and golden brown. You’ll know it’s ready when the top is beautifully bubbly and the sides are slightly crispy. This golden crust adds a delightful texture to the French Onion Ground Beef and Rice Casserole.

Step 7: Serve and Garnish
Remove the casserole from the oven and let it cool for a few minutes before serving. For an extra touch of freshness and color, garnish with chopped parsley if desired. This final flourish not only enhances the presentation but also elevates the flavor profile of your comforting dish.
