Ingredients for Ground Beef Onion Soup Rice Bake
Main Ingredients:
1 tsp olive oil
1 tsp butter
½ medium onion, diced
1 cup sliced mushrooms
1 lb lean ground beef
1 pkg Lipton Onion Soup Mix
1/2 tsp black pepper
1 1/2 cups white rice
10.5 oz can beef consommé or beef broth
10.5 oz can French onion soup
1/2 cup beef broth
1 stick butter (cut into pieces)
Optional Toppings or Garnishes:
French fried onions
Green onions
Shredded Swiss cheese or Gruyere
How to Make French Onion Ground Beef and Rice Casserole
- Sauté the onions and mushrooms: Preheat your oven to 400°F. Heat a large skillet over medium-high heat and add 1 teaspoon each of olive oil and butter. Add chopped onion and sliced mushrooms, cooking until the onions soften and the mushrooms release their juices.
- Brown the ground beef: Add the ground beef to the skillet along with the Lipton Onion Soup Mix and black pepper. Cook until browned, breaking it apart with a spatula. Drain any excess grease, then set aside.
- Mix and assemble the casserole: Spray a 9×13 baking dish with nonstick cooking spray. Add the uncooked rice, beef consommé, beef broth, and French onion soup into the prepared baking dish. Stir in the cooked beef mixture and mix well so everything’s evenly distributed.
- Butter it up and bake: Cut the stick of butter into small pieces and dot them all over the top of the mixture. Cover the dish tightly with foil and bake for 30 minutes.
Remove the foil, stir, then bake for an additional 30 minutes uncovered. - Add toppings (optional): I prefer this casserole without any toppings. During the last half hour of baking, the rice on top gets crispy, adding a little crunch to the dish. However, if you want to go all out, top your casserole with shredded cheese (Swiss, Gruyere, or Mozzarella are my favorites). Bake for an additional 5 minutes, or until the cheese has melted. Sprinkle with crispy fried onions or chopped green onions for the perfect finishing touch.
