Preheat the Ninja Foodi using Broil for 10 minutes with the basket in. If using a different air fryer, preheat with the basket or cooking surface in the air fryer on the hottest setting for 10 minutes.
Thinly slice the onion into strips. A mandoline works best for this and I set mine on 2 mm.
Melt the butter in a medium size bowl and add the onions.
Combine ⅔ cup of flour with 1 teaspoon fine grind sea salt and 1 teaspoon onion powder. Mix well. I like to use these coating trays, but a large shallow container of any kind will work.
Place a few onion strips at a time into the flour mixture to coat. Try to keep them from clumping together. Repeat until all onions are coated.
Spritz the basket with oil of your choice and place the coated onions in a single layer. Spritz the top with oil. Air Crisp/Air Fry on 375°F/190°C for 5 minutes. Toss the onions around a bit and separate them if needed. Air Crisp/Air Fry for another 1-2 minutes. Remove the onions and let them cool on a cooling rack. Repeat if needed for the remaining onions.
Green Bean Casserole
Add fresh green beans, sliced mushrooms, ½ onion diced, and 1 teaspoon sea salt, ½ teaspoon black pepper, ½ teaspoon dried thyme leaves to the inner pot.
Cut the end off of the bulb of garlic. Peel and smash the garlic cloves, add to the pot.
Add ¾ cup of beef stock (or chicken stock) and ¼ cup of sherry OR 1 cup of beef or chicken stock. Stir and place the reversible rack in the high position.
In a 6" Fat Daddio pan, add ¼ cup of room temp butter and ¼ of flour and make a paste. Cover the pan and put on the rack.
Put the pressure lid on and turn the valve to seal. Pressure cook on high for ZERO minutes. Do an immediate release. Remove the pan with the butter/flour and the rack.
Stir the butter/flour so it is well combined and add it to the inner pot. Add in ½ cup of heavy cream and stir. Turn the sear/sauté on low-medium and heat just until the sauce thickens. Stir and top with air fried onions. Air Crisp/Air Fry on 400°F/200°C for 5 minutes.
