Main Ingredients

  • 1 lb ground beef Lean beef for a lighter option
  • 3 cups cooked white rice Long grain or jasmine; leftover rice works perfectly
  • 1 can condensed French onion soup Use your favorite brand or homemade version
  • 1 cup sour cream Swap Greek yogurt for a higher protein, tangier twist
  • 1 cup shredded mozzarella cheese Gruyère or provolone for a stronger flavor
  • 2 tbsp butter For richness and to help brown the beef
  • 1 tsp onion powder Can use fresh chopped onion for texture
  • 1 tsp garlic powder Or 2-3 cloves fresh minced garlic
  • 1 tbsp chopped parsley Optional, for garnish

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C) and grease a 9x13 baking dish.

Cooking

  • In a large skillet over medium-high heat, melt the butter and add the ground beef. Cook until browned, about 6-8 minutes.
  • Drain excess grease if necessary, then stir in onion powder and garlic powder.
  • In a larger bowl, combine the cooked rice, beef mixture, French onion soup, and sour cream. Mix gently until combined.
  • If the mixture is too thick, add 2-4 tablespoons of water or beef broth to reach a spoonable consistency.
  • Transfer the mixture to the prepared baking dish and spread evenly. Top with shredded mozzarella cheese.
  • Bake for 25-30 minutes or until bubbling and cheese is melted. Optional: Broil for 1-2 minutes for a deeper color.
  • Allow to cool for 5-10 minutes before serving. Garnish with parsley if desired.

Notes

You can assemble the casserole earlier and refrigerate. Add extra baking time if baking from cold. Leftovers can be stored in airtight containers for 3-4 days or frozen in single portions.
