Yes, they potato skins can be made ahead of time! You can bake the potatoes and scoop them out, allow the skins to cool completely and place them in a tightly sealed container for up to 2 days. The bacon can be cooked ahead of time and kept in the fridge. Shred the cheese and chop the green onions up to 2 days ahead of time, too, refrigerating them until needed. When it comes time to make the loaded skins, brush the butter on, and pop them in the oven or air fryer. Then proceed with filling and cooking. The prepped potato skins can also be frozen for longer storage. Let them cool completely and place them in a freezer safe airtight container or ziptop bag. They’ll keep for several months in the freezer. Bake these potato skins right from frozen, no need to defrost first.
