How to Make French Onion Ground Beef and Rice Casserole Recipe
Step 1: Get Ready and Prep
Start by preheating your oven to 350°F (175°C) and greasing a 9×13-inch baking dish. This simple step ensures your casserole won’t stick and will bake evenly—setting the stage for a perfect finish.
Step 2: Brown the Beef
Cook the ground beef in a skillet over medium heat until it’s nicely browned. Don’t forget to drain the excess grease to keep things from becoming too oily, and season the beef subtly with salt, pepper, and a bit of garlic powder for extra flavor that enhances the French onion notes.
Step 3: Combine the Rice Mixture
In a mixing bowl, whisk together the uncooked rice, French onion soup mix, and beef broth. This blend is what makes the rice so flavorful as it cooks, absorbing every bit of the French onion richness and beefiness.
Step 4: Bring in the Creaminess and Beef
Add the cooked ground beef along with the sour cream to the rice mixture. Stir well so that the sour cream blends into the broth, creating a creamy texture that makes every bite smooth and luscious.
Step 5: Prepare for Baking
Transfer the mixture into your prepared baking dish and sprinkle the shredded cheese evenly on top. This layer will melt down into a gooey, golden blanket that’s utterly delicious.
Step 6: Bake Covered then Uncovered
Cover your dish with foil to keep moisture locked in and bake for 40 minutes. Then remove the foil and bake for another 10 to 15 minutes, allowing the cheese to bubble and brown just right—getting that gorgeous cheesy crust.
Step 7: Add the Crunchy Finish
Sprinkle the French-fried onions on top of the bubbling cheese and bake for an additional 5 minutes. This step gives you that irresistible crispy, golden topping that elevates the entire dish.
Step 8: Cool and Serve
Once out of the oven, let the casserole cool for a few minutes so it sets slightly, making it easier to serve and letting all those flavors settle beautifully.
How to Serve French Onion Ground Beef and Rice Casserole Recipe
Garnishes
For an inviting presentation and added flavor, sprinkle freshly chopped parsley or chives on top before serving. These fresh herbs add a lovely pop of color and a subtle brightness that lifts the savory richness of the casserole.
Side Dishes
This casserole shines perfectly as a complete meal, but you can complement it with a crisp green salad, steamed veggies like green beans or broccoli, or a fresh baguette to soak up any extra sauce. These sides provide balancing freshness and texture.
Creative Ways to Present
For a fun twist, serve individual portions in small ramekins topped with fresh herbs and additional French-fried onions.

Make Ahead and Storage
Storing Leftovers
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. The flavors continue to meld, making it just as tasty for quick lunches or dinners later in the week.
Freezing
This dish freezes beautifully. Place it in a freezer-safe container before baking or freeze any leftovers. When frozen, it will keep well for up to 2 months. Be sure to thaw overnight in the fridge before reheating for best results.
Reheating
When you’re ready to enjoy the casserole again, reheat it covered in the oven at 350°F (175°C) for about 20 minutes, or until warmed through. You can also microwave individual servings for a faster option, though the oven will help retain that crispy topping.
FAQs
Can I use a different type of cheese in the French Onion Ground Beef and Rice Casserole Recipe?
Absolutely! Mozzarella and Swiss are classic choices for their melting qualities, but feel free to experiment with cheddar, Gruyère, or even a mix of cheeses for a different flavor profile.
Do I need to cook the rice before adding it to the casserole?
Nope! The uncooked rice gently cooks during baking, absorbing all the savory liquids. Just make sure you use the right amount of broth to keep everything moist and tender.
Can I substitute ground beef with another protein?
Yes, ground turkey, chicken, or even plant-based meat substitutes can work well. Just adjust cooking time if necessary and season accordingly.
Is this recipe suitable for meal prepping?
It definitely is! The French Onion Ground Beef and Rice Casserole Recipe reheats well and gets even more flavorful over time, making it an excellent choice for batch cooking.
What if I don’t have French-fried onions?
You can make your own crispy topping by toasting breadcrumbs with a little butter or simply omit it. Although it adds great crunch and traditional French onion flavor, the casserole will still be delicious without it.
