How to Make French Onion Ground Beef And Rice Casserole
Step 1: Sauté the Onions
In a large skillet, heat the olive oil over medium heat. Add the sliced onions and a pinch of salt. Sauté the onions for about 15-20 minutes, stirring occasionally, until they are soft and caramelized, turning a lovely golden brown. This step is crucial as it builds the flavor base of the dish.
Step 2: Brown the Ground Beef
Once the onions are caramelized, push them to one side of the skillet and add the ground beef. Cook it over medium-high heat until browned, breaking it apart with a wooden spoon. This should take about 7-10 minutes. Drain any excess fat if necessary.
Step 3: Combine Ingredients
Stir in the cooked rice, French onion soup, garlic powder, black pepper, and salt to the skillet with the beef and onions. Mix everything thoroughly until well combined. The mixture should be rich and flavorful; taste and adjust the seasoning if needed.
Step 4: Transfer to Baking Dish
Preheat your oven to 350°F (175°C). Pour the beef and rice mixture into a greased 9×13 inch baking dish, spreading it evenly. This will ensure even cooking and melting of the cheese.
Step 5: Add Cheese and Bake
Sprinkle the shredded cheese generously over the top of the casserole. Cover the dish with aluminum foil and bake in the preheated oven for 25-30 minutes. Then, remove the foil and bake for an additional 10-15 minutes, or until the cheese is bubbly and golden brown.
What to Serve With
This French Onion Ground Beef and Rice Casserole pairs wonderfully with a simple green salad or steamed vegetables for a balanced meal. For drinks, consider serving a crisp white wine or sparkling water with lemon for a refreshing touch.
Tips for Success
- Don’t rush the caramelization of the onions; patience is key for achieving that sweet, rich flavor.
- Make sure to use day-old rice for the best texture; fresh rice can become mushy.
- Taste the mixture before baking to ensure it’s seasoned to your liking.
- Feel free to experiment with different cheese blends for added flavor and texture.
Common Mistakes to Avoid
- Skipping the caramelization of onions, which can lead to a lack of depth in flavor.
- Using uncooked rice, which can result in a dish that is not cooked through.
- Not covering the casserole with foil while baking, causing the top to burn before the inside is heated through.
How to Store & Reheat

To reheat, preheat your oven to 350°F (175°C). Cover the casserole with aluminum foil to prevent it from drying out, and heat for about 20-30 minutes, or until warmed through. You can also microwave individual portions on medium power for 2-3 minutes, stirring halfway through.
