Step‑by‑Step Instructions for French Onion Ground Beef and Rice Casserole
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). This temperature is perfect for creating a beautifully baked French Onion Ground Beef and Rice Casserole. While the oven heats, gather your ingredients and a 9×13-inch baking dish, ensuring everything is ready for seamless assembly.
Step 2: Cook the Ground Beef
In a large skillet over medium heat, add the ground beef and cook until it’s no longer pink, which should take about 5-7 minutes. Use a spatula to break it apart for even cooking. Once browned, drain excess fat, leaving about a tablespoon to keep the meat juicy, and then set the beef aside.
Step 3: Sauté the Onions
Reduce the heat to medium-low and add butter to the same skillet. Once melted, add your sliced onions and sauté them for 10-15 minutes until they become golden brown and caramelized. Stir occasionally to prevent sticking and to enhance their sweetness—this step is crucial to achieving that classic French onion flavor.
Step 4: Combine the Ingredients
After the onions are caramelized, stir the uncooked long-grain white rice into the skillet with the onions. Next, add the cream of mushroom soup, beef broth, and any seasonings you wish to include. Mix these ingredients thoroughly to ensure the rice absorbs all the delicious flavors in your French Onion Ground Beef and Rice Casserole.
Step 5: Assemble the Casserole
Transfer the mixture into your greased 9×13-inch baking dish and evenly spread it out. Cover the dish tightly with aluminum foil to create a steamy environment that allows the rice to cook perfectly as it bakes.
Step 6: Bake the Casserole
Place the covered casserole in the preheated oven and bake for 25 minutes. This initial baking step allows the rice to absorb the broth and flavors from the beef and onions, creating a rich, hearty base for your meal.
Step 7: Add the Cheese
After 25 minutes, carefully remove the foil from the baking dish. Sprinkle the shredded cheddar cheese generously over the top of your casserole. The cheese will melt and create a deliciously gooey layer, making this French Onion Ground Beef and Rice Casserole even more irresistible.
Step 8: Final Bake
Return the uncovered casserole to the oven and bake for an additional 10 minutes, or until the cheese is bubbling and golden brown. Keep an eye on it during the last few minutes to achieve that perfect, melty topping that everyone will love.
Step 9: Cool and Serve
Once baked, let the casserole sit for 5 minutes before serving. This allows the flavors to meld together and makes it easier to portion out for your family or guests. Serve warm and watch everyone savor this comforting French Onion Ground Beef and Rice Casserole!
