FAQ

Can I use frozen chicken breasts?

Thaw completely first as frozen chicken won't absorb the marinade and will cook unevenly in the air fryer.

What if I don't have buttermilk?

Mix 1 cup milk with 1 tablespoon lemon juice or vinegar, let sit 5 minutes until slightly thickened.

How long will marinated chicken keep?

Raw marinated chicken stays fresh 1-2 days refrigerated, while cooked chicken keeps 3-4 days properly stored.
