Preheat the air fryer: Set to 375°F (190°C). Let it heat while you prep. Line the basket with perforated parchment or a reusable liner to prevent sticking.

Season the cheese: Lay the cheese slices on a parchment-lined tray or board. Lightly sprinkle with Italian seasoning, garlic powder, and a pinch of Parmesan.

Add pepperoni: Place 3–4 slices of pepperoni on each cheese slice. Keep them slightly away from the edges so they don’t spill out when rolled.

Air fry the base: Lightly spray the lined air fryer basket. Arrange 3–4 prepared cheese slices in a single layer, seasoning side up, without overlapping. Air fry for 3–4 minutes until the cheese is bubbly and the edges turn golden.

Roll while hot: Carefully remove each cheese slice with tongs. Let it sit for about 10–15 seconds to firm slightly, then roll up from one side into a tight log. Work quickly before it cools and hardens.

Repeat in batches: Continue cooking and rolling until all slices are done. Don’t crowd the basket; cheese needs space to crisp.

Quick crisp finish: Return the rolled logs to the air fryer for 1–2 more minutes to set the seam and crisp the exterior. Sprinkle with remaining Parmesan if you like.

Warm the sauce: Heat the low-carb marinara in a small saucepan or microwave-safe bowl. Add crushed red pepper if you want heat.

Garnish and serve: Top roll ups with chopped basil or parsley. Serve hot with warm marinara for dipping.
