Ingredients You'll Need

This French Onion Ground Beef and Rice Casserole Recipe relies on simple but essential ingredients that each play a vital role—from tender rice providing the perfect base, to the richly flavored ground beef and the classic French onion soup that brings all the savory goodness together. Here’s everything you’ll need before you get cooking:

1 pound ground beef (lean): Provides hearty protein and a savory base for the casserole.
½ to 1 teaspoon garlic salt: Adds just the right kick of garlic with a bit of salt to enhance flavor.
2 (10.5 ounce) cans beef consommé: Deepens the beefy richness and moistens the rice during baking.
2 (10.5 ounce) cans French onion soup: The star ingredient, giving the dish its iconic sweet onion flavor and savory broth.
¾ cup water: Helps cook the rice thoroughly and balances the soup’s intensity.
2 cups long grain white rice (uncooked): The fluffy, tender grains absorb all the delicious broth and flavors as it bakes.
¾ cup butter (1 ½ sticks, cut into slices): Melts over the top to add richness and helps create a golden crust.

How to Make French Onion Ground Beef and Rice Casserole Recipe

Step 1: Prepare Your Oven and Dish

Start by preheating your oven to 425°F. While it’s warming up, grab a 9x13 inch baking dish and spray it generously with cooking spray to prevent sticking and ensure easy cleanup later.

Step 2: Brown the Ground Beef

In a large skillet, add your lean ground beef along with the garlic salt for seasoning. Cook over medium heat, stirring frequently and breaking the beef apart until it’s nicely browned and cooked through. This step builds a rich, meaty foundation for your casserole.

Step 3: Combine Ingredients in the Baking Dish

Transfer the cooked ground beef into your prepared baking dish along with the uncooked rice. Next, pour in both cans of French onion soup, beef consommé, and the water. Stir everything together until it’s well combined—the rice will soak up all those wonderful flavors during baking.

Step 4: Add Butter on Top

Slice the butter into evenly sized pieces and scatter them over the top of the mixture. This will melt during cooking, adding luscious richness and helping form a beautiful golden crust.

Step 5: Bake Covered

Cover the baking dish tightly with foil to trap steam and bake in the preheated oven for 30 minutes. This steams the rice and allows flavors to meld perfectly.

Step 6: Uncover and Continue Baking

After 30 minutes, remove the foil and bake uncovered for an additional 30 minutes. This step finishes cooking the rice and lets the top brown nicely. For an extra touch, try adding a sprinkling of shredded cheese before uncovering for a cheesy and crispy topping experience.

Step 7: Fluff and Serve

Once your casserole is baked to perfection, fluff the rice gently with a fork to separate the grains and serve it up hot. The layers of beef, rice, and that iconic French onion flavor make this dish an absolute crowd-pleaser.

FAQs

Can I use brown rice instead of white rice in this recipe?

Absolutely! Brown rice will add a nuttier flavor and a bit more chewiness, though the baking time might need to be extended slightly to ensure it cooks fully.

Is it possible to make this casserole vegetarian?

Yes, substitute the ground beef with plant-based crumbles or cooked lentils, and use vegetable broth instead of beef consommé for a delicious vegetarian twist.

What can I add for a cheesy topping?

Sprinkle shredded Swiss, Gruyere, or cheddar cheese on top before removing the foil for the last 30 minutes of baking to achieve a melty, golden crust.

Can I prepare this casserole in advance and bake later?

Definitely! Assemble the casserole up to step 4, cover tightly, and refrigerate overnight. Then bake it fresh the next day for a stress-free meal.

How spicy is the French Onion Ground Beef and Rice Casserole Recipe?

This recipe is mostly savory and mild, thanks to the French onion soup base, but you can always add a pinch of cayenne or red pepper flakes when browning the beef if you like a little heat.
