Make sure you have your potato skins ready to go. See notes for links to recipes for potato skin shells.
Preheat oven to 350F.
Once your potato skins are prepared (see note below for recipe), place them skin side down on a large cookie sheet.
Defrost the spinach if using frozen and squeeze out any excess liquid.
In a small bowl, combine the cream cheese, Parmesan cheese, spinach, chopped artichoke hearts, sour cream, garlic powder, red pepper flakes, and salt. Season to taste as desired with more of any ingredient.
Fill each potato skin shell with the mixture. Sprinkle the tops of the potato skins with some additional Parmesan cheese.
Bake until the cheese on top is starting to brown and the cheese filling is hot and starting to bubble, approximately 12-15 minutes. Serve immediately.
