Expert Tips:
- If you are using the silicone donut sheets to prepare your homemade keto onion rings try sitting them on a baking pan this way they are easy to place in the oven and remove from the oven.
- For extra crispy onion rings try double baking them. Once you have removed them from the oven and cooled them. Take a couple of the onion rings and place them on a sheet of parchment paper in the air fryer for 5 minutes at 360 degrees and you will get the best onion cheese crisp.
- For any leftovers just freeze them in a Zip Loc bag. They are perfect as toppers for burgers. I like to place the frozen onion rings in the air fryer on top of my veggie burger..gourmet style!
- If you want a low carb breading for your onion rings you can just crush up pork rinds, dip your rings in an egg wash then dunk in almond flour for a low carb batter then back in the egg wash and then dip in the crushed pork rinds.
