Freeze mozzarella sticks for an hour or two. Take mozzarella sticks out of refrigerator and cut in half so that each cheese stick is 2-3 inches long.
Mix Italian style bread crumbs, Panko bread crumbs, Parmesan cheese and garlic powder together in a bowl. Beat eggs together in a separate bowl.
Using a fork, fully cover the mozzarella stick with egg and then dip and fully cover the mozzarella stick with the breadcrumb mixture. Place mozzarella sticks onto a nonstick pan. Make sure that they are not touching each other.
Freeze for one hour. Remove mozzarella sticks from the freezer and dip the mozzarella stick in the egg and breadcrumb mixture again. This second coating will help add to the crispiness once cooked.
Lightly spray the air crisping basket with non stick cooking spray. Gently place the mozzarella sticks into the air crisping basket. Be sure that there is a little space in between each. Lightly spray the mozzarella sticks with the non stick cooking spray.
Turn Instant Pot Duo Crisp on and choose “air fry.” Set temperature to 360 degrees and “air fry” them for 8-10 minutes. Check them at about 7 minutes-just open up the lid. If they are evenly browned and cheese is just barely starting to melt through the batter, they are done cooking. If they have not browned yet, put the lid back on and allow to cook for 2-3 minutes longer.
When the mozzarella sticks are cooked, carefully remove from Instant Pot Duo Crisp with tongs. Serve with marinara sauce. Enjoy!
