Step‑by‑Step Instructions for Easy French Onion Ground Beef and Rice Casserole
Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This will ensure that your Easy French Onion Ground Beef and Rice Casserole cooks evenly and thoroughly. While the oven warms up, grab your trusty 9 x 13-inch baking dish and give it a nice spritz with nonstick spray to prevent the casserole from sticking.
Step 2: Brown the Beef and Onions
In a large skillet over medium-high heat, add the pound of lean ground beef. Break it apart with a spatula as it cooks, stirring occasionally until it’s nicely browned, about 5-7 minutes. Add the diced yellow onions to the skillet and cook for an additional 3-4 minutes until the onions are golden and fragrant, creating an irresistible aroma that fills your kitchen.
Step 3: Season the Mixture
Once your beef and onions are perfectly browned, stir in the salt, pepper, and onion soup mix. Combine everything well while removing the skillet from heat. This flavor-packed mixture will serve as the heart of your casserole and will elevate the overall taste of the French Onion Ground Beef and Rice dish.
Step 4: Assemble the Casserole
Spread the uncooked instant white rice evenly across the bottom of the prepared baking dish. Layer the savory beef and onion mixture over the rice, making sure to distribute it evenly. Finally, pour the beef broth over the top, ensuring the grains of rice will soak up all those delicious flavors during baking.
Step 5: Bake the Casserole
Cover the baking dish tightly with aluminum foil and place it into the preheated oven. Bake the casserole for 40 minutes, allowing the rice to absorb the broth and become tender. During this time, the wonderful aroma of the casserole will build a sense of anticipation in your home.
Step 6: Add the Creamy Topping
After 40 minutes, carefully remove the foil from the baking dish. Spoon the creamy sour cream over the beef mixture, followed by a generous sprinkling of shredded mozzarella cheese and crispy fried onions. This will create a delightful, gooey topping that enhances the overall comfort of your Easy French Onion Ground Beef and Rice Casserole.
Step 7: Bake Uncovered
Return the dish to the oven and bake uncovered for an additional 10-15 minutes. Keep an eye on it; you want the cheese to melt beautifully and become bubbly with a golden hue on top. This final step adds a delightful texture and visual appeal that’s sure to impress your family and friends.
Step 8: Rest and Serve
Once the cheese is perfectly melted, remove the casserole from the oven and let it rest for a few minutes before serving. If desired, garnish with freshly chopped parsley for a pop of color. Now, your Easy French Onion Ground Beef and Rice Casserole is ready to take center stage on the dinner table, inviting everyone to dig in!
