Introduction

This French Onion Ground Beef and Rice Casserole is a comforting one-pan meal that combines the rich, savory flavors of classic French onion soup with tender rice, hearty ground beef, and melted Gruyere cheese. It’s perfect for busy weeknights when you want something satisfying with minimal cleanup.

The dish shows a close-up of cooked rice with a mix of brown and light tan grains, some pieces having a slightly crispy texture. On top, there is a layer of cooked ground meat, dark brown and crumbly. Above the meat, there is a melted cheese layer with a golden brown crust and small bits of green herbs sprinkled on top. The scene is set against a white marbled surface. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

1 lb ground beef

1 large onion, thinly sliced

2 tbsp butter

2 cloves garlic, minced

2 cups beef broth (low-sodium recommended)

1 tbsp soy sauce

1 tsp Worcestershire sauce

1/2 tsp dried thyme

1 cup uncooked long-grain white rice (do not rinse)

1/2 cup heavy cream

2 cups shredded Gruyere or Swiss cheese, divided

Salt and freshly ground black pepper to taste

Fresh parsley, chopped, for garnish

Instructions

Step 1: Preheat your oven to 375 degrees F (190 degrees C).

Step 2: In a large oven-safe skillet over medium-high heat, cook the ground beef, sliced onion, and butter together for 8-10 minutes until the beef is fully browned and the onions are softened and golden. Drain any excess grease.

Step 3: Add the minced garlic to the skillet and cook for 1 minute until fragrant.

Step 4: Stir in the beef broth, soy sauce, Worcestershire sauce, dried thyme, uncooked rice, salt, and pepper. Bring the mixture to a simmer on the stovetop.

Step 5: Remove the skillet from heat. Stir in the heavy cream and 1 cup of the shredded cheese until the mixture is creamy and well combined.

Step 6: If you are not using an oven-safe skillet, transfer the mixture to a 9×13 inch casserole dish. Sprinkle the remaining 1 cup of cheese evenly over the top.

Step 7: Bake uncovered for 25-30 minutes until the liquid is mostly absorbed, the rice is tender, the edges are bubbly, and the cheese on top is golden and melted.

Step 8: Let the casserole rest for 5-10 minutes before serving. Garnish with fresh chopped parsley.

Tips & Variations

For a deeper onion flavor, cook the onions alone in butter for 15-20 minutes before adding the ground beef.

If the top browns too quickly before the rice is fully cooked, cover loosely with foil for the last 10 minutes of baking.

Do not use instant rice, as it will become mushy. Long-grain white rice is essential for the best texture.

Do not rinse the rice before using; the starch helps thicken the sauce as it bakes.

To freeze, assemble the casserole through step 6, cover tightly, and freeze for up to 3 months. Thaw overnight before baking.

FAQs

Can I use a different type of cheese?

Yes, Swiss cheese works well as a substitute for Gruyere. You can also try other melty cheeses like fontina or mozzarella, but the flavor will be less traditional.
