Ingredients

How To Make Cheesy Ground Beef and Rice Casserole

Step 1: Prepare the Oven
Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish.

Step 2: Brown the Beef
In a large skillet over medium heat, cook the ground beef with the chopped onion and minced garlic until the beef is fully browned and the onion is tender. Season with the salt, black pepper, and paprika, then drain off any excess fat.

Step 3: Mix Everything Together
In a large mixing bowl, stir together the cream of mushroom soup, sour cream, and milk until smooth. Add the cooked beef mixture, cooked rice, and 1 cup of the shredded cheddar cheese. Fold in the frozen peas if you’re using them.

Step 4: Fill the Baking Dish
Transfer the mixture to the prepared baking dish and spread it into an even layer. Sprinkle the remaining 1 cup of shredded cheddar cheese evenly over the top.

Step 5: Bake the Casserole
Place the dish in the preheated oven and bake for 25–30 minutes, or until the filling is hot and bubbling and the cheese is melted with a lightly golden top.

Step 6: Finish and Serve
Allow the casserole to rest for a few minutes before serving. Garnish with chopped fresh parsley, if desired, for a pop of color and fresh flavor.
