Garlic knots are traditionally served with a marinara sauce, but that is not the only type of sauce that is absolutely delicious with them. A simple garlic butter sauce is perfect or if you really want to impress, make some of this garlic parmesan wing sauce for dipping, you will not regret it! Another few simple dipping sauce ideas are ranch dressing or a parsley butter. Honestly, they are so good and so buttery right out of the air fryer, you can skip the dipping sauce!
