Step‑by‑Step Instructions for French Onion Ground Beef and Rice Casserole
Step 1: Sauté Onions
Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add 2 sliced onions and cook for 10-12 minutes, stirring occasionally, until they soften and turn golden brown. This caramelization enhances their sweetness and adds depth to the French Onion Ground Beef and Rice casserole.
Step 2: Brown Beef
In the same skillet, add 1 pound of ground beef, breaking it into small pieces with a spatula. Cook for 5-7 minutes, stirring until the beef is nicely browned and cooked through. Drain any excess grease to keep the casserole light and flavorful, then combine the beef with the caramelized onions.
Step 3: Prepare Rice
Rinse 1 cup of long-grain white rice under cold water until the water runs clear, removing excess starch for better texture. You can either cook the rice separately or add it uncooked directly to the casserole for a one-pan experience. If adding uncooked, ensure it is thoroughly mixed with the liquid later.
Step 4: Combine Ingredients
In a large mixing bowl, combine the beef and onion mixture with the rinsed rice and 2 cups of beef broth. Stir well to blend all the flavors, ensuring the rice is evenly distributed. This combination forms the hearty base of your French Onion Ground Beef and Rice casserole.
Step 5: Bake
Transfer the mixture to a greased 9×13 inch baking dish. Cover the dish tightly with aluminum foil to create steam. Bake in a preheated oven at 350°F (175°C) for 30 minutes. This step allows the rice to cook and absorb the delicious flavors, creating a comforting and cohesive dish.
Step 6: Add Cheese
After 30 minutes, carefully remove the foil and sprinkle 1 cup of shredded Swiss cheese evenly over the top of the casserole. Return the dish to the oven, uncovered, and bake for an additional 10-15 minutes, or until the cheese is melted and bubbly, creating a rich layer on top of the casserole.
Step 7: Final Touch
Scatter 1 cup of crispy fried onions on top of the melted cheese and bake for another 5 minutes until the onions are golden brown and crunchy. This final touch adds texture and flavor, completing your French Onion Ground Beef and Rice casserole in a delightful way.
