White onion flakes

White onion flakes are dehydrated, thinly sliced or chopped pieces of white onion, produced through a controlled drying process that preserves their flavor and extends shelf life. These flakes provide a convenient, shelf-stable alternative to fresh onions, offering a quick and efficient way to incorporate the distinctive, mildly pungent flavor of white onion into a wide range of culinary applications without the need for peeling, chopping, or refrigeration.
