Ingredients

Scale

For the Casserole

  • 1 lb Ground Beef (lean beef is healthier)
  • 3 cups Cooked White Rice (long grain or jasmine rice yields the best results)
  • 1 can Condensed French Onion Soup (a homemade version can elevate this dish)
  • 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)
  • 1 tsp Onion Powder (substitute fresh onions for robust taste)
  • 1 tsp Garlic Powder (fresh garlic also works great)
  • 1 tbsp Chopped Parsley (optional, as a fresh garnish)

Instructions

  1. Preheat and Prepare: Preheat your oven to 350°F (175°C) and generously grease a 9×13-inch baking dish to prevent sticking, ensuring easy removal of the casserole after baking.
  2. Cook the Ground Beef: Melt 2 tablespoons of butter in a large skillet over medium heat. Add 1 pound of lean ground beef and cook until browned and fully cooked, then drain any excess fat for a lighter dish.
  3. Season the Beef: Stir in 1 teaspoon onion powder, 1 teaspoon garlic powder, salt, and pepper to taste, mixing well to evenly coat the meat with these flavors.
  4. Combine Ingredients: In a mixing bowl, combine the cooked beef with 3 cups of cooked white rice, 1 can of condensed French onion soup, and 1 cup of sour cream. Stir until the mixture is well incorporated and creamy throughout.
  5. Assemble the Casserole: Spread the beef and rice mixture evenly into the prepared baking dish, then top generously with 1 cup of shredded mozzarella cheese, covering every corner with cheesy goodness.
  6. Bake: Place the casserole in the oven and bake for 25-30 minutes, or until the cheese is melted, bubbly, and golden brown on top.
  7. Garnish and Serve: Remove from the oven and sprinkle 1 tablespoon of chopped fresh parsley over the top for a bright, fresh garnish before serving.

Notes

  • Use day-old rice to improve texture and flavor absorption, preventing sogginess.
  • Broil the casserole for an additional 2-3 minutes at the end of baking if you desire a crispier, golden cheese topping—watch carefully to avoid burning.
  • Avoid overcooking ground beef to keep it juicy and tender.
  • Feel free to add sautéed mushrooms or chopped bell peppers for extra flavor and nutrition.
  • You can substitute ground turkey or chicken for a leaner protein option.
  • Freeze leftovers in airtight containers for up to 2 months; thaw overnight and reheat in the oven at 300°F until warmed through.
  • Do not freeze the casserole with cheese topping; add fresh cheese before baking after thawing.
