How to Make French Onion Ground Beef and Rice Casserole
Step 1: Caramelize the Onions
Start by thinly slicing yellow onions and cooking them slowly in butter over medium heat until they turn golden brown and sweet. This process unlocks the deep flavor that’s the heart of the French onion character in the casserole.
Step 2: Brown the Ground Beef
Once your onions are caramelized, push them aside and add the ground beef to the skillet. Cook until browned, breaking it into small pieces with a spatula, then drain any excess fat.
Step 3: Prepare the Rice Mixture
Add garlic, French onion soup mix, Worcestershire sauce, beef broth, and rice to the beef and onion mixture. Stir everything together, ensuring the rice is well distributed and coated with flavors.
Step 4: Assemble and Bake
Transfer the beef, onion, and rice mixture into a greased casserole dish. Top generously with shredded Swiss or Gruyere cheese, then bake at 350°F (175°C) for about 30-35 minutes or until the rice is tender and the cheese is bubbly and golden.
Step 5: Rest and Serve
Let the casserole rest for a few minutes before scooping and serving to allow the flavors to meld and the cheese to set slightly.
Pro Tips for Making French Onion Ground Beef and Rice Casserole
- Slow Caramelizing: Don’t rush the onions—low and slow heat yields the best sweetness and color.
- Brown Beef Thoroughly: Proper browning adds depth and richness to the dish.
- Rice Type Matters: Use long-grain or jasmine rice for fluffiness; avoid short grain that can get mushy.
- Cheese Quality: High-quality Swiss or Gruyere melts better and enhances the flavor significantly.
- Let It Rest: Resting the casserole after baking makes serving easier and prevents it from falling apart.
