1.) Wash and scrub the potato thoroughly. Pat dry and slice thinly into 1/8-inch rounds.
2.) Put the sliced potatoes in a saucepan and cover with cold water. Option to add 3 crushed garlic cloves to the water to impart more flavor.
3.) Par boil the potatoes for 5 minutes until they are slightly tender.
4.) Thaw 1 sheet of puff pastry and roll out slightly with a rolling pin. Cut into 12 equal strips.
5.) On a foiled lined tray generously sprayed with oil, sprinkle 1 tsp of parmesan and a pinch of Italian seasoning, then shingle 3-4 slices of the par-cooked potato slices with 3-4 slices of pepperoni. Top the slices with ~1 1/2 tbsp mozzarella, followed by a strip of the puff pastry. Push the edges of the pastry down onto the foil to slightly “seal” the puffs, allowing the contents to remain within the pastry.
6.) Bake in a 400-degree F air fryer for 7-8 minutes.
7.) Wait for the cheese to cool before trying to remove the puffs from the tray. Gently peel the potato pizza puffs off the foil. Serve with marinara sauce and enjoy!
