Here’s the magic of this casserole—it’s made with just a few pantry staples, but the result is so much more than the sum of its parts. Let’s break it down:
Ground Beef: The heart of the dish, providing rich, savory flavor. Browning it first ensures a delicious base.

Instructions
Let’s dive into the steps to create this flavorful masterpiece:
Preheat Your Oven: Start by preheating your oven to 350°F. This ensures even cooking and gives your dish the right texture. Preheating is a small but essential step that sets the stage for success.
Cook the Ground Beef: In a large skillet over medium heat, cook the ground beef until browned and fully cooked. Drain any excess grease. This step builds the base of the casserole with a delicious, savory foundation.
Sauté the Onions: Add the chopped onions to the skillet and cook until they are soft and golden, enhancing the dish with a subtle sweetness.
Combine the Ingredients: In a mixing bowl, stir together the cooked beef, sautéed onions, French onion soup, beef broth, and uncooked rice. Mix until everything is well combined.
Prepare the Baking Dish: Lightly grease a baking dish to prevent sticking and make cleanup a breeze.
Assemble the Casserole: Pour the mixture into the prepared dish and spread it evenly. Cover tightly with aluminum foil to lock in moisture.
Bake to Perfection: Bake for 45-50 minutes, or until the rice is tender and has absorbed all the liquid.
Add the Cheese: Remove the foil, sprinkle cheese on top, and return to the oven for another 5-10 minutes, until the cheese is melted and bubbly.
Let it Rest: Remove from the oven and let it sit for about 5 minutes before serving. This helps the flavors meld together beautifully.
Serve and Enjoy: Dish it up while it’s warm, and watch everyone dig in with excitement!

Instructions

- In a large skillet over medium heat, cook the ground beef seasoned with garlic salt until browned and cooked through. Drain any excess fat.

Notes
- For a cheesy variation, during the last 10 minutes of baking, sprinkle 1½ cups of shredded cheese (such as provolone, Swiss, or mozzarella) over the casserole and bake until melted and bubbly.
- To reduce dishwashing, you can use an oven-safe skillet or Dutch oven to cook the ground beef, then add the remaining ingredients and bake directly in it.
