Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper.
Divide the shredded mozzarella into 8 equal small mounds, leaving at least 2 inches between each mound.
Place 2 pepperoni slices over each cheese mound. If using Italian seasoning or red pepper flakes, sprinkle a tiny amount over the top.
Place the baking sheet in the 400°F oven and bake for approximately 8–10 minutes. Watch closely during the final few minutes.
The cheese should be completely melted, bubbling, and golden brown around the edges.
Remove the baking sheet and let the chips cool for 2–3 minutes. They will firm up considerably as they cool.
Use a thin spatula to carefully lift the chips from the parchment. Serve immediately with warm marinara sauce, if desired.
