This dip can be assembled up to 24 hours in advance and refrigerated before baking, then baked straight from the fridge, adding a few extra minutes as needed until hot and bubbly. For a milder version, start with less Buffalo sauce and add more to taste, and for extra richness you can drizzle a little additional ranch over the hot dip just before serving. Leftovers keep well in an airtight container in the refrigerator for up to 3 days and can be reheated in the oven or in short microwave bursts with stirring until creamy again.
