- Preheat your air fryer to 360 degrees F for 3-5 minutes. Preheating ensures that the zucchini cooks evenly and gets a crispy texture. Wash the zucchini thoroughly and cut them into evenly sized sticks or rounds. Aim for a thickness of about ¼ to ½ inch slices for even cooking. 
- Pour flour (3 tbsp) into a plastic bag and put zucchini there. Tie the ends of the bag and shake gently a few times.  
- Each piece of zucchini will be evenly coated with flour. Beat an egg into another bowl. Add flour, milk, salt, and also paprika, and mix everything thoroughly with a whisk. If you see that the batter is too liquid, add more flour; if too thick, pour in a little milk. 
- Roll the floured zucchini circles in the thick dough on both sides. In another bowl, pour breadcrumbs and roll each circle of zucchini in breadcrumbs so they are completely covered. 
- Place the zucchini pieces in the air fryer basket, set the air fryer temperature to 360 degrees F, and set the cooking time for  12-15 minutes, flipping halfway during the cooking process.  
- Serve with your favorite dipping sauce.
