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

Step 1: Preheat the Oven
Begin your delicious journey by preheating the oven to 375°F (190°C). This step ensures that your French Onion Ground Beef and Rice Casserole bakes evenly and comes out perfectly golden. While the oven is warming up, gather your ingredients to streamline the cooking process and make it feel effortless.

Step 2: Cook the Ground Beef
In a large skillet over medium heat, add your ground beef and cook for about 5-7 minutes until browned and no longer pink. Use a wooden spoon to break it up as it cooks. Once done, drain most of the grease but leave about a tablespoon in the pan for added flavor. This step creates a savory base for your casserole.

Step 3: Caramelize the Onions
Lower the heat to medium-low, then add butter to the skillet, allowing it to melt before adding thinly sliced onions. Cook the onions for 10-15 minutes, stirring occasionally, until they are golden brown and fragrant. This caramelization enhances the flavor profile of your French Onion Ground Beef and Rice Casserole, infusing it with a sweet depth that balances the beef.

Step 4: Combine Ingredients
Once the onions are beautifully caramelized, stir in uncooked long-grain white rice, cream of mushroom soup, beef broth, and your chosen seasonings. Mix everything well until combined. This mixture is the heart of the casserole, and the rice will absorb all the delicious flavors as it bakes to perfection.

Step 5: Prepare for Baking
Transfer the mixture into a greased 9×13-inch baking dish, spreading it out evenly for even cooking. Cover the dish tightly with foil to trap steam inside, ensuring the rice cooks thoroughly. Place it in the preheated oven and bake for 25 minutes to allow the flavors to meld beautifully.

Step 6: Add Cheese and Finish Baking
After the initial baking time, carefully remove the foil and sprinkle a generous layer of shredded cheddar cheese on top of the casserole. Return the dish to the oven without the foil and bake for an additional 10 minutes. The cheese should be melted, bubbly, and slightly golden, indicating it’s ready to be savored.

Step 7: Rest Before Serving
Once out of the oven, let the casserole sit for about 5 minutes to set. This resting period allows the flavors to settle and makes serving easier. As the aroma fills your kitchen, you’ll know your French Onion Ground Beef and Rice Casserole is ready to be enjoyed by all.
