Ingredients

Scale

Beef Mixture

  • 1 lb Ground Beef (Lean beef is healthier.)
  • 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.)
  • Salt and Pepper to taste

Rice Mixture

  • 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.)

Topping

  • 1 cup Shredded Mozzarella Cheese (Gruyère or provolone work for stronger flavor.)
  • 1 tbsp Chopped Parsley (Optional, as a fresh garnish.)

Instructions

  1. Preheat and Prepare: Preheat your oven to 350°F (175°C). Generously grease a 9×13-inch baking dish to ensure the casserole does not stick during baking.
  2. Cook the Beef: Melt the butter in a large skillet over medium heat. Add the ground beef and cook it until browned and fully cooked, breaking up any chunks as it cooks. Drain off any excess fat to keep the dish from becoming greasy.
  3. Season the Beef: Add onion powder, garlic powder, salt, and pepper to the browned beef. Stir well to evenly distribute the seasonings and boost the flavor.
  4. Mix Ingredients: In a large mixing bowl, combine the cooked beef with the cooked white rice. Stir in the condensed French onion soup and sour cream until the mixture is thoroughly combined, creating a creamy, flavorful base.
  5. Assemble the Casserole: Spread the beef and rice mixture evenly into the prepared baking dish. Sprinkle the shredded mozzarella cheese evenly over the top to create a gooey, cheesy crust once baked.
  6. Bake: Place the casserole in the preheated oven and bake for 25-30 minutes, or until the cheese has melted completely and is golden brown on top.
  7. Garnish and Serve: Remove from the oven and, if desired, sprinkle with chopped fresh parsley for a pop of color and freshness before serving warm.

Notes

  • For a lighter alternative, substitute sour cream with Greek yogurt.
  • Using freshly chopped onions and garlic can enhance the flavor more than onion and garlic powder.
  • Gruyère or provolone cheese can be used instead of mozzarella for a stronger cheese flavor.
  • Ensure to drain excess fat from the cooked beef to prevent the casserole from being too greasy.
  • This casserole can be prepared ahead of time and refrigerated before baking; just add a few extra minutes to the baking time if cold from fridge.
