Step 10: Rest and Serve Remove the casserole from the oven and let it rest for 5-10 minutes before serving. This resting period allows the dish to set slightly, making it easier to serve and ensuring the cheese doesn’t run everywhere when you cut into it. Garnish with fresh parsley or green onions if desired, and serve your cheesy ground beef and rice casserole hot with your favorite sides.
Notes
Rice Type Matters: Use long-grain white rice for best results in this cheesy ground beef and rice casserole. Instant rice will become mushy, while brown rice requires significantly more liquid and cooking time.
Liquid Ratio: The rice needs adequate liquid to cook properly. If you prefer softer rice or notice your casserole seems dry after the first baking period, add an extra ½ cup of broth before adding the cheese.
Ground Beef Fat Content: An 80/20 or 85/15 fat ratio provides the best flavor and moisture. Leaner beef can result in a drier casserole, so if using 90/10, consider adding an extra tablespoon of oil.
Cream Soup Substitute: If you want to avoid canned soup, make a simple white sauce using 3 tablespoons butter, 3 tablespoons flour, and 1½ cups milk cooked until thickened.
Make-Ahead Note: You can assemble this casserole completely (without the cheese topping) up to 24 hours in advance. Cover and refrigerate, then add 10 extra minutes to the covered baking time since it will be cold.
