Ingredients

Scale

Meat and Dairy

  • 1 lb Ground Beef (Lean beef is healthier.)
  • 1 cup Sour Cream (Greek yogurt can be used as a lighter alternative.)
  • 1 cup Shredded Mozzarella Cheese (Gruyère or provolone work for stronger flavor.)
  • 2 tbsp Butter (Enhances richness when cooking the beef.)

Grains

  • 3 cups Cooked White Rice (Long grain or jasmine rice yields the best results.)

Pantry Items & Seasoning

  • 1 can Condensed French Onion Soup (A homemade version can elevate this dish.)
  • 1 tsp Onion Powder (Substitute fresh onions for robust taste.)
  • 1 tsp Garlic Powder (Fresh garlic also works great.)
  • Salt and Pepper to taste

Garnish

  • 1 tbsp Chopped Parsley (Optional)

Instructions

  1. Preheat Oven: Preheat the oven to 350°F (175°C) and generously grease a 9×13-inch baking dish to ensure the casserole doesn’t stick during baking.
  2. Cook the Beef: Melt the butter in a large skillet over medium heat. Add the ground beef and cook, stirring occasionally, until browned and fully cooked through. Drain any excess fat to keep the dish lean.
  3. Season the Beef: Stir in the onion powder, garlic powder, salt, and pepper to the cooked beef, mixing well to evenly coat the meat with the spices for enhanced flavor.
  4. Combine Ingredients: In a large mixing bowl, combine the cooked beef, cooked white rice, condensed French onion soup, and sour cream. Stir thoroughly until all components are well incorporated into a creamy mixture.
  5. Assemble the Casserole: Spread the beef and rice mixture evenly in the prepared baking dish. Sprinkle the shredded mozzarella cheese evenly over the top to create a cheesy crust.
  6. Bake: Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the cheese is melted, bubbly, and golden brown on top.
  7. Garnish and Serve: Remove the casserole from the oven and let it cool for a few minutes. Garnish with chopped parsley if desired. Serve warm for a comforting meal.

Notes
