Preheat and prep: Heat your oven to 375°F (190°C). Line two large baking sheets with parchment paper or silicone baking mats. Don’t skip the liner—it prevents sticking and makes cleanup easier.
Season the cheese: In a bowl, toss the shredded Pepper Jack with garlic powder, onion powder, smoked paprika, and a pinch of cayenne if you want extra heat.
Add a few grinds of black pepper. Mix until evenly coated.
Portion the mounds: Scoop about 1 tablespoon of seasoned cheese per crisp onto the lined baking sheets. Space them at least 2 inches apart.
They will spread as they melt.
Shape lightly: Pat each mound into a loose circle about 2 inches wide. Keep the cheese in a thin, even layer for maximum crunch.
Add garnish (optional): If using jalapeño, sprinkle a few tiny bits onto the center of each circle. Press lightly so they adhere.
Bake: Place sheets on the middle racks and bake for 7–10 minutes, rotating halfway if your oven has hot spots.
The crisps are ready when the edges turn deep golden and the centers look set, not bubbly wet.
Cool for crispness: Remove from the oven and let the crisps cool on the sheet for 5 minutes. Then transfer to a wire rack to finish crisping. They firm up as they cool, so be patient.
Taste and adjust: Once cool, taste one.
If you want more heat or smoke next time, adjust spices accordingly. Serve right away or store for later.
