Divide: Cut the pizza dough into 12 equal pieces on a lightly floured surface.
Roll: Roll each piece into a 6-inch rope.
Knot: Tie each rope into a loose overhand knot, tucking the ends under.
Garlic butter: In a small bowl, whisk together the melted butter, minced garlic, Parmesan, parsley, salt, and Italian seasoning. Set aside.
Air fry: Lightly spray the air fryer basket with olive oil. Arrange knots in a single layer (work in batches if needed). Air fry at 350°F (175°C) for 6–7 minutes, until deep golden brown.
Double-dunk: Immediately transfer the hot knots to a large bowl. Pour half the garlic butter over them and toss to coat. Brush or drizzle the remaining butter on top.
Serve: Sprinkle with extra Parmesan and parsley. Serve warm with marinara for dipping.
