01 - Preheat oven to 400°F or preheat air fryer to 375°F. Line a baking sheet with parchment paper if using the oven method.
02 - Lay flour tortillas flat on a clean work surface. Spread 2-3 tablespoons of pizza sauce in the center of each tortilla, leaving a 1-inch border around the edges clear of sauce.
03 - Distribute mozzarella cheese evenly among all tortillas. Top with pepperoni (or mushrooms), bell peppers, black olives, red onion, dried oregano, and garlic powder. Ensure even distribution for consistent flavor.
04 - Fold the left and right edges of each tortilla inward by about 1 inch. Starting from the bottom edge, roll up tightly burrito-style to completely enclose the filling. Press gently to seal.
05 - Lightly brush or spray the exterior of each burrito with olive oil. This coating promotes even browning and crispy texture during cooking.
06 - Arrange burritos seam-side down on prepared baking sheet for oven cooking, or place in air fryer basket without overcrowding. Cook in batches if necessary.
07 - Oven method: Bake for 18-20 minutes until golden brown and crisp. Air fryer method: Cook for 8-10 minutes, flipping burritos halfway through cooking time, until exterior is crisp and lightly browned.
08 - Remove from heat and let rest for 2 minutes. Sprinkle with grated Parmesan cheese and fresh basil leaves if desired. Serve immediately with extra pizza sauce or ranch dressing for dipping.
