Coconut flour or almond flour – Light, gluten-free flour for keto-friendly breading
Salt – Enhances flavor and balances the seasoning blend
Eggs – Helps the breading stick and creates golden coating
Pork rinds – Crunchy, low-carb alternative to traditional breadcrumbs
Paprika – Adds mild spice and beautiful reddish color

How To Make Air Fryer Keto Onion Rings

Three bowls with coconut flour and salt, beaten eggs, and a seasoned pork rind mixture prepared for dredging keto onion rings.

Step One: Line your air fryer basket with parchment paper to prevent sticking.

Step Two: Set up three dredging stations: In one bowl add the coconut flour and salt, in the second bowl with beaten eggs, and a third with ground pork rinds, almond flour, paprika, and garlic salt.

Three bowls lined up for dredging: one with coconut flour and salt, one with beaten eggs, and one with seasoned pork rind coating.

Step Three: Dip each onion ring into the coconut flour first, then the eggs, and finally coat them in the pork rind mixture. Place each coated ring onto the prepared parchment-lined basket.

Step Four: Lightly spray the rings with non-aerosol cooking spray for extra crispiness.
Set air fryer temperature to 400 degrees F and set cook time for 8-10 minutes, or until golden and fully cooked through.

Keto Onion Rings Air Fryer Recipe Tips

Choose the Right Onion: For crispy onion rings, use large sweet onions like yellow or white onions. They offer a perfect balance of sweetness and crunch.
Cut Consistently: Slice the onions into even rings to ensure they cook evenly in the air fryer.
Crispier Coating: Double-dip the onion rings in the breading for an extra crispy crust. First, coat them in coconut flour, then dip in the egg, and finally, press them into the pork rind mixture.
Don’t Overcrowd: Give each onion ring enough space in the air fryer basket for the hot air to circulate, ensuring they cook evenly and become extra crispy.
Light Spraying: Use non-aerosol cooking spray to lightly coat the onion rings before air frying for an added crunch without excess oil.
Check for Doneness: Air fry at 400°F for 8–10 minutes, but check at the 8-minute mark and adjust the cooking time depending on how crispy you want your onion rings.

Storing, Freezing and Reheating

Storing: Store leftover keto onion rings in an airtight container in the refrigerator for up to 2-3 days to keep them fresh. Be sure to let them cool completely before storing to avoid moisture buildup.
Freezing: To freeze keto onion rings, place them in a single layer on a baking sheet and freeze until solid, then transfer to a freezer-safe bag or container. They can be frozen for up to 1-2 months for later use.
Reheating: Reheat frozen or leftover onion rings in the air fryer at 375°F for about 3-5 minutes to restore their crispy texture. Alternatively, you can reheat them in the oven at 375 degrees F.
