STEP-BY-STEP INSTRUCTIONS TO MAKE KETO ONION RINGS
First Step: Equip All Needed Ingredients
Start by gathering your ingredients and ensuring your air fryer is ready to go. Slice the onions into thick rings, making sure they’re uniform in size. Preheat your air fryer so it’s hot and ready when you’re finished prepping.

Second Step: Prepare Coatings
Combine the almond flour, breadcrumbs, garlic powder, onion powder, paprika, salt, and black pepper in a bowl. Whisk the eggs until well-beaten in a separate bowl to create your wet coating. This will give your onion rings the crispy texture and flavor you want.

Third Step: Dip Onion Rings into the Wet and Dry Coating
Dip each onion ring into the egg wash, making sure it’s fully coated. Then, dip the ring into the dry mixture and press gently to ensure an even coating. Repeat with all the onion rings, ensuring they’re fully coated with wet and dry layers.
Fourth Step: Air Fry Onions
Preheat your air fryer to 400°Fahrenheit (200°Celsius) and lightly grease the basket with EVO oil to prevent sticking. Arrange the coated onion rings in a single layer, ensuring they are not overcrowded for even cooking. Air fry for 8 minutes, allowing them to crisp up and turn golden brown.

Fifth Step: Flip to Cook Evenly
Carefully flip each onion ring using tongs to ensure an even crisp on both sides. Continue air frying for another 5 minutes at 400°Fahrenheit (200°Celsius) until they are perfectly crispy and golden. Remove from the air fryer and serve immediately with your favorite dipping sauce.

TIPS AND TRICKS:
- Double-Coating: For extra crispy onion rings, you can dip them in the egg and dry coating mixture a second time before air frying. Making a batter can also add a layer of crunch.
- Seasoning Variations: Feel free to get creative with the seasoning mix. Adding a pinch of cayenne pepper, dried thyme, or some grated Parmesan cheese can give your onion rings an extra kick.
- Oil Spray: Be sure to spray a light coat of EVO oil on the onion rings and in the air fryer basket for the best crispiness. Too much oil can cause the coating to become soggy.
- Adjust Thickness: Cut the onion slices slightly thicker if you prefer thicker onion rings. Keep in mind that thicker rings may need a little extra cooking time.
