Step-by-Step Instructions for French Onion Ground Beef & Rice

Step 1: Sauté the Onions
Heat the olive oil in a skillet over medium heat. Add thinly sliced onions and cook until caramelized (about 8-10 minutes). This step brings out the signature French onion flavor.
Step 2: Brown the Ground Beef
Add the lean ground beef and minced garlic to the same skillet. Cook until browned and fully cooked. Drain excess fat if needed.

Step 3: Mix the Base
In a large bowl, combine the cooked beef, onions, French onion soup, beef broth, and cooked brown rice. Stir in the Greek yogurt to give it a creamy texture.
Step 4: Assemble the Casserole
Pour the mixture into a greased casserole dish. Top with shredded mozzarella cheese.

Step 5: Bake
Preheat your oven to 375°F (190°C). Bake uncovered for 25-30 minutes, or until the cheese is golden and bubbly.
Step 6: Garnish & Serve
Let it cool for 5 minutes. Garnish with parsley or green onions if desired.
