Making these French Onion Funeral Potatoes is as easy as 1-2-3. Let’s dive into the process:

1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish to prevent sticking.
2. In a large bowl, combine the frozen hash browns, cream of chicken soup, sour cream, 1 cup of cheddar cheese, and the French onion soup mix. Stir until well combined.
3. Spread the mixture evenly into the prepared baking dish. Smooth out the top with a spatula.
4. In a separate bowl, mix the melted butter with the crushed cornflakes or breadcrumbs. Sprinkle this mixture over the potato mixture in the baking dish.
5. Top with the remaining 1 cup of shredded cheddar cheese.
6. Bake in the preheated oven for 45 minutes, or until the top is golden brown and bubbly. Let it cool for a few minutes before serving.

Pro tip: If you like a bit of extra crunch, broil the dish for the last 2 minutes of cooking, but keep an eye on it to prevent burning.
