1-Preheat and Prepare the Dish: First, preheat your oven to 350°F and grease a 9×13-inch casserole dish to keep everything from sticking. This sets the stage for even baking and makes cleanup easy.

2-Mix the Ingredients: Next, in a large bowl, mix the thawed hash browns, melted butter, condensed soup, sour cream, onion, 1 ½ cups of shredded cheese, and black pepper until everything blends well. Spread this mixture evenly in the prepared dish and top it with the remaining ½ cup of shredded cheese for that extra cheesy layer.

3-Bake the Casserole: Then, bake uncovered for 45 to 55 minutes until it’s hot and bubbly. Let it sit for a few minutes after baking to firm up, making it simpler to serve. Adding extras like vegetables or protein can make it even better, as shared in our Ultimate Casserole Guide on the site.

4-Tips for Smooth Preparation: If you’re short on time, assemble it ahead and refrigerate overnight just add a bit more baking time. For a crunchy top, mix 2 cups of crushed cornflakes with ¼ cup melted butter and sprinkle it on before baking.
