What Kind of Ground Beef Should I Use?

For a rich, meaty flavor without too much grease, use lean ground beef (85% lean or higher). It balances the dish nicely and helps keep the texture hearty without becoming oily. If you use fattier beef, make sure to drain excess fat after browning.

Ingredients for the French Onion Ground Beef and Rice Casserole

• Ground beef: The savory base, providing depth and richness.
• Cooked rice: Acts as the comforting bulk that absorbs flavor.
• French onion soup: Adds the signature sweet-savory onion taste.
• Beef broth: Enhances the meaty flavor and helps the rice stay moist.
• Worcestershire sauce: Brings umami to boost the beefiness.
• Shredded cheese: Melts on top for a golden, bubbly finish.
• Butter: Used to sauté and deepen the richness.
• Garlic and onion powder: Simple seasoning to complement the onion soup.
• Fresh thyme (optional): Adds a pop of herby brightness on top.

How To Make the French Onion Ground Beef and Rice Casserole

Step 1: Brown the Beef

In a large skillet over medium heat, cook the ground beef until browned and crumbled. Drain excess fat and return to heat.

Step 2: Build Flavor

Add in butter, garlic powder, and onion powder. Stir in the French onion soup, Worcestershire sauce, and beef broth. Let everything simmer together for 3-5 minutes to develop flavor.

Step 3: Mix with Rice

Stir in the cooked rice until well combined and the liquid is mostly absorbed.

Step 4: Assemble the Casserole

Transfer the beef and rice mixture to a greased 9×13-inch baking dish. Top generously with shredded cheese.

Step 5: Bake and Finish

Bake at 350°F (175°C) for 15-20 minutes or until the cheese is melted and golden. For an extra golden top, broil for 2-3 minutes.
