Air Fryer Dehydrated Onion Flakes & Homemade Sun-dried Onion Powder

Onion flakes, are used in various food preparations such as dry soups, sauces, vegetable mixes, fast foods, etc. The dehydrated onion flakes has same flavor and taste as the freshly chopped onions.

The Onion powder is made by drying sliced onions in the hot sun for 4 -5 days.

But these Onion flakes made in the Air Fryer are quick and easy, got ready in an hour. They were not browned or burnt.

1 Kg Onions each for Flakes & Powder


For the Onion Flakes

Remove root, top, and skins and wash the onions and pat them dry. 
Then using a grater or a chopper, I used my V slicer to cut into fine dices.
Place the diced onions on a clean muslin cloth to dry for 2 to 3 hours at least .
Then place these in the basket of the Air fryer at 80 degrees. Then no need to preheat the Air Fryer. 
Every 15 minutes give it a good stir so that they are evenly dried and crisp. If necessary keep it for another 10 to 15 minutes more.
Ta Da.. they are ready..

I loved making these in the Air Fryer since it is so easy and hassle free. No tension of it getting burnt. Place these again in the dry cloth and leave it overnight so that they are cool and dry completely. Store it in a zip lock bags in the refrigerator.

Use this to make French Onion Soup Mix and this Soup

For the Onion Powder
For this I finely sliced the Onions on my V Slicer. Spread them on a big plate or woven basket and sun dry it for 4 to 5 days, Before drying it the next day toss them well and set it to dry. 
When you find that some have dried, start crushing them with your hand. 
Once dry powder it in a blender. Store in an airtight container.

If it's summer it will get dry in four days or may take more day depending on how strong the sun heat is.
