Made with egg whites, oat ban, flaxseed, Parmesan, and spices, these meatballs are suitable for gluten-free diets. Nutrition info is per meatball. Six meatballs contain 276 calories and 30 grams of protein.
Add all ingredients to a large bowl and mix well with your hands.
Roll into tablespoon-size balls (or use a cookie scoop so there is minimal shaping required) and place into the air fryer basket sprayed with cooking oil spray. Work in batches, if needed, so the basket isn't overcrowded.
Mist the top of the meatballs and air fry for 8-10 minutes, turning half way through.
Notes
The meatball mixture will be sticky, so I usually glove up. Setting the mixture in the freezer for 10 minutes or so and working with wet hands will make it easier to work with. Using a cookie scoop also makes this easier. You can just shape them instead of rolling them.
Don't overcrowd the basket. This recipe yields about 40 meatballs, so you'll most likely need to work in batches.
Use a meat thermometer to make sure the chicken is cooked through (165 degrees F). I recommend cooking them to 160 and resting them in the air fryer basket until they reach 165.
I always give meatball mixtures a taste and adjust the seasonings if necessary. You can roll a 1/2" size meatball and air fry it for 4 to 5 minutes (or until cooked through) to taste before rolling the rest of the mixture.
