Ingredients You’ll Need
Ground Beef (1 lb)
Start with ground beef, cooked until browned. This forms the flavorful foundation of the casserole.
Beef Consommé (2 cans, 10.5 oz each)
A rich, clear soup that enhances the beefy taste and adds depth to the rice as it bakes.
French Onion Soup (2 cans, 10.5 oz each)
These canned soups infuse the dish with a mellow onion flavor and slight sweetness that balances the savory beef.
Long-Grain White Rice (2 cups, uncooked)
This rice cooks right in the dish. It absorbs all the liquid and flavors, staying firm and fluffy.
Water (¾ cup)
A small amount of water helps balance the flavors and provides the moisture needed for the rice to fully cook.
Butter (½ cup, sliced)
Placed on top before baking, the butter melts into the dish, adding richness and helping the rice stay moist.
Mozzarella Cheese (1 cup, shredded)
Used at the end of baking, this cheese melts over the top, creating a creamy, gooey layer.
French Fried Onions (3 oz)
These add crunch and flavor to the final dish, finishing it with a crispy texture and toasted taste.
Garlic Powder (½ teaspoon)
Gives the ground beef a boost of savory flavor without the need for fresh garlic.
Black Pepper (½ teaspoon)
A bit of pepper balances the richness and adds mild spice to the mix.
How to Make French Onion Ground Beef and Rice Casserole
This meal is prepared in layers and baked in two stages. It doesn’t require advanced techniques, just a little prep and a baking dish. As the casserole cooks, the rice softens and soaks up the savory liquid, and the butter and beef help everything meld into a cozy, one-dish dinner.
Step-by-Step Instructions
Step 1: Preheat and Prep
Begin by setting your oven to 425°F. Coat a 9×13-inch baking dish with cooking spray or butter to keep the casserole from sticking.
Step 2: Brown the Ground Beef
Heat a skillet over medium and add the ground beef. Sprinkle in the garlic powder and black pepper. Cook for about 7 to 8 minutes, stirring occasionally until browned. Drain off the extra fat.
Step 3: Mix Ingredients in the Dish
Transfer the cooked beef to the baking dish. Add the uncooked rice, both soups, and water. Stir until everything is evenly mixed, and the rice is well-distributed.
Step 4: Top with Butter Slices
Cut the butter into thin pieces and place them evenly across the surface of the mixture. This helps lock in moisture and boosts flavor during baking.
Step 5: Bake Covered
Cover the baking dish tightly with aluminum foil. Bake for 30 minutes so the rice can cook through in the steam.
Step 6: Bake Uncovered
Remove the foil and continue baking for 25 minutes. This allows excess liquid to reduce and gives the top a slight crisp.
Step 7: Add Cheese and Onions
Once the rice is cooked and the liquid absorbed, sprinkle mozzarella cheese over the top. Then scatter the French fried onions evenly across the surface.
Step 8: Final Bake
Place the dish back in the oven for 5 to 6 minutes, just long enough to melt the cheese and toast the onion topping.
Step 9: Rest and Serve
Take the casserole out and let it sit for a few minutes. Fluff the rice gently with a fork and serve warm.
Helpful Tips
Rice Type Matters
Long-grain white rice is ideal. Avoid quick-cooking rice, which can turn mushy in the oven.
Foil is Key
The first half of baking should be tightly covered. This traps steam, helping the rice cook evenly.
Butter Placement
Distribute the butter across the surface rather than mixing it in. It melts gradually into the rice as it cooks.
Cooking Tools
Use a glass or ceramic dish for even baking. Metal pans may cook faster and can brown the edges too much.
Storage
Leftovers can be stored in an airtight container for up to 4 days in the refrigerator. To freeze, portion into containers once cooled, then reheat in the oven or microwave with a splash of broth or water to refresh the texture.

Notes and Variations
To make this dish lighter, ground turkey or chicken can be used instead of beef. If you’d like to include veggies, stir in peas, corn, or spinach after the covered baking stage. Swap mozzarella for Swiss or cheddar for a sharper or deeper flavor. If you want to use brown rice, add more liquid and increase the baking time by 20–25 minutes to allow for proper cooking.
