Build this dip the night before if you want: assemble without baking, cover tightly, and refrigerate up to 2 days. Add 5 to 8 extra minutes to the bake time when starting from cold. Pat pepperoni dry with a paper towel before chopping — this keeps the top glossy instead of oily. Shred mozzarella from a block for the stretchiest melt. Leftovers keep 3 to 4 days in the fridge; reheat at 325°F for 10 minutes. Freezing is not recommended — cream cheese turns grainy when thawed.
