Using a pastry brush, brush half of the oil onto the basket of your air fryer. This will keep the batter from sticking to the basket as it cooks. Set the basket aside.
2 tablespoons olive oil
Set out 3 small bowls. Add ½ cup of flour to one bowl. In a second bowl, whisk together the remaining ½ cup flour, milk, and seasonings. Fill the third bowl with the breadcrumbs. Place the bowls next to each other for easy dipping.
1 cup all-purpose flour, ½ cup milk, 1 teaspoon kosher salt, ½ teaspoon ground black pepper, ½ teaspoon ground paprika, 1 cup breadcrumbs
Dip each piece of chicken into the flour.
1 pound boneless, skinless chicken breasts
From the flour mixture, move the nugget to the milk/seasonings mixture and toss to coat.
Finally, coat each piece with breadcrumbs and place it into the oiled air fryer basket without stacking.
Repeat coating for each piece, until all are covered and in the basket (note: don't crowd the basket. You may need to air fry in batches).
Brush the nuggets with the remaining oil. Select chicken, make sure the temperature is 380°F, and cook on each side for 7 minutes. If you prefer extra crispy, you can cook an additional minute on each side.
Serve Immediately.
