Make Ahead Options
These French Onion Funeral Potatoes are a fantastic choice for meal prep! You can prepare the casserole mixture (without the fried onions) up to 24 hours in advance, just combine the frozen hash browns, melted butter, cheese, sour cream, sautéed onions, and the creamy sauce before transferring it to your baking dish. Cover tightly with plastic wrap and refrigerate. When you’re ready to cook, simply bake it straight from the fridge, adding an extra 5-10 minutes to the baking time. For the crispy onion topping, prepare them just before serving to maintain their crunch; store them in an airtight container at room temperature to keep them fresh.
