This French Onion Ground Beef Rice Casserole layers all the cozy flavors of classic French onion soup into a hearty, family-friendly bake. Tender rice, savory ground beef, caramelized onions, and creamy mushroom sauce all melt together under a blanket of Swiss cheese for a one-pan dinner that feels special but stays weeknight easy.
Ingredients
- 1 pound ground beef
- 1 cup long-grain white rice, uncooked
- 2 cups beef broth
- 1 large onion, thinly sliced
- 2 tablespoons olive oil
- 1 can (10.5 ounces) cream of mushroom soup
- 1 cup shredded Swiss cheese
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- Salt and pepper to taste
- Fresh parsley, chopped (for garnish)
Instructions
- Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish and set aside.
- In a large skillet, heat the olive oil over medium heat. Add the thinly sliced onion and cook, stirring occasionally, for 10–12 minutes, or until deeply golden and caramelized.
- Add the ground beef to the skillet with the onions. Cook, breaking it apart with a spatula, for 5–7 minutes or until browned and cooked through. Drain off any excess fat.
- Season the beef and onion mixture with the garlic powder, onion powder, salt, and pepper. Stir well to combine and remove from the heat.
- In a large mixing bowl, combine the uncooked long-grain white rice, beef broth, cream of mushroom soup, and the cooked beef-onion mixture. Stir until everything is evenly incorporated.
- Pour the mixture into the prepared 9×13-inch baking dish and spread it into an even layer. Sprinkle the shredded Swiss cheese evenly over the top.
- Cover the dish tightly with aluminum foil and bake for 30 minutes. Remove the foil and continue baking for an additional 10–15 minutes, or until the rice is tender, most of the liquid is absorbed, and the cheese is melted and bubbly.
- Let the casserole rest for 5–10 minutes before serving. Garnish with chopped fresh parsley and scoop into bowls or onto plates.
Variation
- Swap the Swiss cheese for Gruyère or a Swiss–Mozzarella blend for an even more classic French onion flavor and extra meltiness.
- Stir in 1/2–1 cup of sliced mushrooms or frozen peas before baking for added texture and veggies.
- Use brown rice instead of white; increase the beef broth to 2 1/2 cups and extend the covered baking time by 15–20 minutes, checking for doneness.
Cooking Notes
- Use long-grain white rice (not instant or parboiled) so it cooks evenly and absorbs the flavorful broth in the oven.
- Make sure the casserole is tightly covered with foil for the first part of baking to trap steam and help the rice cook through.
- If the top browns too quickly once the foil is removed, loosely tent the dish again and continue baking until the rice is tender.
Serving Suggestions
- Serve with a simple green salad and crusty bread or dinner rolls to soak up the savory sauce.
- Pair with roasted or steamed vegetables like green beans, broccoli, or carrots for a balanced plate.
- Top each serving with extra fresh parsley, a sprinkle of grated Parmesan, or a spoonful of sour cream for added richness.
Tips
- Slice the onion as evenly as possible so it caramelizes at the same rate and doesn’t burn.
- For deeper flavor, deglaze the skillet after caramelizing the onions with a splash of beef broth or dry white wine, scraping up any browned bits before adding the beef.
- To meal prep, assemble the casserole up to the point of baking, cover, and refrigerate up to 24 hours. Add 5–10 extra minutes of baking time if going straight from the fridge to the oven.

Frequently Asked Questions
- Can I use pre-cooked rice instead of uncooked?
Yes. Use about 3 cups of cooked rice and reduce the beef broth to 1 cup. Mix everything together, bake covered for 15 minutes, then uncover and bake until hot and bubbly. - Can I make this casserole ahead of time?
You can assemble it up to 24 hours in advance, cover tightly, and refrigerate. When ready to bake, let it sit at room temperature for 15–20 minutes and add a few extra minutes of bake time if needed. - What kind of onion works best?
Yellow onions are ideal for caramelizing because they turn sweet and flavorful, but white onions or sweet onions will also work well. - How do I store and reheat leftovers?
Store cooled leftovers in an airtight container in the refrigerator for up to 3–4 days. Reheat in the microwave or covered in a 325°F (165°C) oven until warmed through, adding a splash of broth if it seems dry.

Notes
- Caramelizing the onions slowly is key to building that deep French onion flavor—don’t rush this step.
- If your oven runs hot, check the casserole a few minutes early to be sure the rice doesn’t overcook or dry out.
- This casserole thickens as it rests, so letting it sit for at least 5–10 minutes makes it easier to scoop and serve.
