Preheat the air fryer: Set your air fryer to 375°F (190°C). Let it heat for 3–5 minutes so the bites start crisping right away.

Prep the dough: Lightly flour your surface. Roll or stretch the pizza dough into a rectangle about 9x12 inches. Aim for about 1/2-inch thickness so the bites stay soft inside.

Cut into bites: Use a knife or bench scraper to cut the dough into 1-inch squares. If you like, gently round the edges with your fingers, but it’s not required.

Make the garlic butter: In a small bowl, mix melted butter, olive oil, minced garlic, salt, pepper, red pepper flakes (if using), and half the parsley. Stir in half the Parmesan.

Toss the dough: Add the dough pieces to a large bowl. Pour over half the garlic butter and toss to coat. Reserve the rest for after cooking.

Prep the basket: Lightly spray or brush the air fryer basket with oil to prevent sticking. Don’t use aerosol spray directly if your basket’s manual advises against it; brush on oil instead.

Arrange and cook: Place the dough bites in a single layer with a little space between them. Cook for 6–8 minutes, shaking the basket or turning the bites halfway through, until golden and puffed.

Finish with flavor: Transfer hot bites to a bowl. Toss with the remaining garlic butter, the rest of the Parmesan, and the remaining parsley. Taste and add a pinch more salt if needed.

Repeat if needed: If you have more dough, cook in batches to avoid overcrowding. Bites crisp better with space.

Serve warm: Enjoy right away with marinara or your favorite dip.
