French Onion Ground Beef and Rice Casserole Recipe
For this amazing casserole, you’ll need the following ingredients
Ingredients
- 1 lb ground beef
- 2 cans or 10.5-ounce beef consommé
- 2 cans or 10.5-ounce French onion soup
- 2 cups long-grain white rice
- 1 cup shredded mozzarella cheese
- ¾ cup water
- ½ cup butter
- ½ tsp garlic powder
- ½ tsp black pepper
- 3 oz French fried onions
Optional Add-ons
- Sautéed mushrooms for extra flavor
- Fresh herbs, such as parsley or thyme, for garnish
Step-by-Step Instructions for French Onion Beef Casserole with Rice
Step 1: Preheat the Oven
Preheat your oven to 425°F (220°C). Spray a 9×13-inch baking dish with cooking spray to prevent sticking and make cleanup easier.
Step 2: Cook the Onions
Sauté the onion for about 3-5 minutes on medium heat, just until it softens—no need to fully caramelize it. Keep stirring to avoid browning. Once done, transfer it to a plate.
Step 3: Cook the Ground Beef
In a large skillet, heat the ground beef over medium heat. Add the garlic powder and black pepper and cook the beef, crumbling it as it cooks. Stir occasionally until the beef is fully browned and no longer pink, about 7-8 minutes. Once browned, drain any excess fat and set the beef aside.
Step 4: Combine the Ingredients
In the prepared baking dish, add the uncooked rice and the cooked ground beef. Pour in the beef consommé, French onion soup, and water. Stir everything together until well combined, ensuring the rice is evenly distributed in the mixture.
Step 5: Add Butter
Cut the butter into slices and place the slices evenly over the top of the casserole mixture. This will melt during baking and add richness to the dish.
Step 6: Cover and Bake
Cover the baking dish with foil to lock in moisture and bake for 30 minutes. This step helps cook the rice while keeping it tender and flavorful.
Step 7: Uncover and Continue Baking
After 30 minutes, remove the foil and continue baking for an additional 25 minutes, allowing the casserole to cook through and the top to become slightly golden. You’ll know it’s done when the rice is tender and the broth has absorbed into the rice.
Step 8: Final Bake
Top the dish with mozzarella cheese and French fried onions and bake for another 5-6 minutes, or until the cheese is melted and the onions crispy golden.
Step 9: Serve
Once baked, remove the casserole from the oven and let it cool for a few minutes. Use a fork to fluff the rice before serving, ensuring it has a light, airy texture.
Storage and Serving
Leftover French Onion Beef Casserole can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, simply microwave individual portions or warm the casserole in the oven at 350°F until heated through.
If you want to freeze the casserole, cover it tightly with plastic wrap and foil before freezing. It can be frozen for up to 3 months and reheated in the oven.
Tips for Success
- Brown the Beef Well: Make sure to cook the beef thoroughly and brown it well to enhance the flavor of the casserole.
- Use Long-Grain Rice: Do not use minute rice for this recipe, as it does not cook the same way and may affect the texture.
- Adjust Seasoning: Depending on the saltiness of your beef consommé and French onion soup, adjust the garlic salt to your taste. If you prefer a stronger onion flavor, consider adding a bit of onion powder.
Variations
- Mushroom Lovers: For extra depth of flavor, sauté some mushrooms and add them to the casserole mixture before baking.
- Spicy Kick: Add a pinch of red pepper flakes or a diced jalapeño to the beef for a spicy version of the casserole.
