Ingredients
Using a 2-Tbsp. cookie scoop, scoop risotto into 24 portions and transfer to a parchment-lined baking sheet. Create an indent in center of each ball, place a piece of mozzarella in indentation, and form risotto around mozzarella, tightly packing into a ball and making sure risotto completely covers mozzarella.
In a shallow dish, whisk flour and garlic powder (if using); season with salt and pepper. In another shallow dish, beat eggs to blend. In a third shallow dish, combine panko and Pecorino; season with pepper.
Working one at a time, coat risotto balls in seasoned flour, shaking off excess. Dip into eggs, then into panko mixture.
Coat an air-fryer basket with cooking spray. Arrange half of balls in basket; spray tops with cooking spray. Cook at 400°, turning halfway through, until golden brown, about 15 minutes.
Transfer arancini to a platter. Top with Pecorino Romano; season with pepper. Serve with marinara and pesto alongside.
