Step‑by‑Step Instructions for French Onion Ground Beef Rice Casserole
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This ensures that your cozy French Onion Ground Beef Rice Casserole will bake evenly and thoroughly, providing the perfect melt on the cheese topping later. While the oven warms up, you can get your ingredients organized and gather the necessary cookware, such as a large skillet and a greased 9×13-inch baking dish.
Step 2: Brown the Ground Beef
In a large skillet, heat over medium heat and add the ground beef. Use a wooden spoon to break it apart as it cooks, browning it for about 5-7 minutes until no longer pink. Drain any excess fat to keep your casserole from becoming greasy. The ground beef will contribute rich flavor to your casserole, so ensure it’s nicely browned before proceeding to the next step.
Step 3: Sauté the Onions
In the same skillet, melt a tablespoon of butter over medium-low heat. Once melted, add the thinly sliced onions and sauté them, stirring occasionally, for about 10-15 minutes until they turn golden brown and caramelized. The sweet aroma will fill your kitchen, signaling that you’re on the right path to creating a delicious French Onion Ground Beef Rice Casserole.
Step 4: Combine Ingredients
Once the onions are dreamy and caramelized, return the browned ground beef to the skillet. Stir in the French onion soup, beef broth, and Worcestershire sauce, ensuring all ingredients are mixed well. Allow this mixture to simmer for 2-3 minutes over low heat. This will meld the flavors together beautifully, creating a savory filling that will coat the rice perfectly.
Step 5: Add the Rice
Stir in the uncooked long-grain white rice, ensuring it’s well-coated with the meat and onion mixture. This will help the rice absorb all those delicious flavors while it cooks. Once everything is combined, it’s time to transfer this savory mixture to the prepared baking dish for the next stage of your French Onion Ground Beef Rice Casserole journey.
Step 6: Prepare for Baking
Pour the rice and beef mixture into your greased 9×13-inch baking dish, smoothing it into an even layer with a spatula. Cover the dish tightly with aluminum foil to trap moisture, which is essential for the rice to cook properly. Place the dish in your preheated oven and bake for 45-50 minutes. By the end of this time, the rice should be tender, and the liquid mostly absorbed.
Step 7: Add the Cheese
After 45-50 minutes, carefully remove the foil from the baking dish. Sprinkle a generous layer of shredded cheese over the top of the casserole. Return the dish to the oven and bake uncovered for an additional 5-10 minutes, or until the cheese has melted and is bubbly with a beautiful golden crust. This step transforms your French Onion Ground Beef Rice Casserole into a gooey delight.
Step 8: Let It Rest
Once your casserole is bubbly and golden, remove it from the oven and let it rest for about 5-10 minutes. This helps the flavors to set and makes serving easier. If you like, sprinkle some fresh parsley on top for a pop of color and freshness. Now you’re ready to dig into your heartwarming French Onion Ground Beef Rice Casserole!
