How to Make Air Fryer Onion Strings Recipe
Step 1: Slice Your Onions Thinly
Start by peeling your onion and slicing it into very thin rings. For the most consistent thickness and crispiness, I highly recommend using a mandolin slicer. Thin onion strings cook evenly and have that perfect snap when you bite into them.
Step 2: Soak Onions in Buttermilk
Place the sliced onions in a medium bowl, then pour the buttermilk over them. Let the onions soak for at least 15 minutes. This soaking step softens the onions slightly and adds moisture so the coating clings better, ensuring every string is perfectly coated and flavorful.
Step 3: Prepare the Flour Mixture and Preheat the Air Fryer
While your onions are getting cozy in the buttermilk bath, combine the flour, garlic powder, smoked paprika, salt, cayenne, and black pepper in another bowl. This spice mix is where magic happens by adding the smoky, spicy, and savory notes your onion strings will be bursting with. Preheat your air fryer to 375°F (190°C) during this time so it’s ready to crisp your strings just right.
Step 4: Dredge the Onion Strings in Flour Mixture
Spray your air fryer basket lightly to prevent sticking before working with a few onions at a time. Remove onions from the buttermilk and dredge each ring thoroughly in the flour mixture. Make sure they’re well coated but not clumped together, then tap off any excess flour for an even fry.
Step 5: Air Fry Until Golden and Crispy
Place your coated onion strings in an even layer in the air fryer basket. Lightly spray the top with cooking spray to encourage crisping. Air fry them at 375°F for 8 to 10 minutes, flipping them halfway through for even browning. Depending on your air fryer size, you might need to work in batches to avoid overcrowding.
Step 6: Finish and Serve
Once beautifully golden and crisp, transfer your onion strings to a serving plate and sprinkle with coarse salt to enhance their flavor. Serve immediately while hot for that signature crunch and irresistible taste.

Garnishes
A sprinkle of fresh herbs like parsley or chives adds a pop of color and fresh flavor that pairs wonderfully with the smoky crispness of the onion strings. A light dusting of extra smoked paprika can also boost color and aroma, making them even more satisfying.
Side Dishes
These crispy onion strings are fantastic alongside burgers, steaks, or grilled chicken, acting as a crunchy counterbalance. They also pair beautifully with fresh salads or creamy dips such as ranch, sriracha mayo, or barbecue sauce, expanding your flavor horizons.
Creative Ways to Present
Try piling the onion strings on top of open-faced sandwiches or loaded fries for added crunch. They also make a stunning garnish for salads or bowls, adding texture and dimension. A rustic wooden platter or a colorful bowl also adds charm to their irresistible appeal.
Make Ahead and Storage
Storing Leftovers
If you want to save leftovers, let the onion strings cool to room temperature and then store them in an airtight container lined with paper towels to absorb any excess moisture. They’re best eaten within a day to maintain their crispness.
Freezing
Freezing onion strings isn’t ideal because the coating can lose its crisp texture when thawed. However, if you must, flash freeze them spread out on a baking sheet, then transfer to a freezer bag. Reheat in the air fryer to revive some of their crisp.
Reheating
The best way to bring back the original crispiness is to pop leftover onion strings back into the air fryer for a few minutes at 375°F. Avoid microwaving as this will make them soggy and less appetizing.
FAQs
Can I use a different type of onion?
Absolutely! While yellow and white onions work best for this recipe due to their natural sweetness and firmness, you can experiment with red onions for a slightly sharper flavor and a splash of color.
Do I need buttermilk, or can I substitute it?
Buttermilk adds a tangy richness that tenderizes the onions and helps the coating stick. If you don’t have buttermilk, you can mix regular milk with a tablespoon of vinegar or lemon juice and let it sit for a few minutes.
Is it necessary to flip the onion strings during air frying?
Flipping helps achieve even browning on all sides. If you’re cooking smaller batches and can space the strings enough, you might not need to flip, but it’s recommended for uniform crispness.
Can I make these gluten-free?
Yes! Use a gluten-free flour blend in place of all-purpose flour. Just make sure the blend has a good balance of starch and protein to help keep the coating crispy and flavorful.
What dipping sauces go best with Air Fryer Onion Strings?
Classics like ranch and barbecue are amazing, but don’t be afraid to try spicy sriracha mayo, tangy honey mustard, or even bleu cheese dip for a flavorful twist.
