Prepare the Filling: In a mixing bowl, combine blueberries, lemon zest, lemon juice, granulated sugar, chopped nuts, and ground cinnamon. Gently toss to combine and set aside.
Set Up Phyllo Dough: Lay out a sheet of phyllo dough on a clean surface. Brush a thin layer of melted butter over the sheet, then place another sheet on top and brush with butter again. Repeat the process until you have 4-6 layers, depending on the desired sturdiness.
Add the Filling: Spoon about 2 tablespoons of the blueberry and nut mixture along one edge of the layered phyllo dough. Be careful not to overfill.
Roll the Strudel: Fold in the sides of the phyllo over the filling, then starting from the edge with the filling, roll the dough tightly into a log shape. Seal the ends well to prevent the filling from leaking out.
Prepare for Air Frying: Lightly brush the outside of the rolled strudel with melted butter for a golden finish. Repeat steps 2-5 for the remaining phyllo sheets and filling.
Air Fry the Strudels: Preheat your air fryer to 350. Arrange the strudels in the air fryer basket in a single layer, making sure they are not overcrowded. Air fry for 10-12 minutes or until they are golden brown and crispy.
Cool and Serve: Once cooked, remove the strudels from the air fryer and let them cool for a few minutes. Dust with powdered sugar if desired, and serve warm with a side of vanilla ice cream or a dollop of whipped cream.
Notes
Optional to dust with powdered sugar before serving.
