Red onion flakes are dried, finely chopped pieces of red onion that have been dehydrated to preserve their flavor and extend their shelf life. These flakes retain the characteristic mild, sweet, and slightly tangy flavor of fresh red onions, but with a more concentrated taste due to the drying process. They are commonly used as a seasoning or garnish in various dishes.

Red onion flakes are convenient and easy to use, adding a burst of onion flavor to soups, salads, dressings, dips, sauces, and seasoning blends without the need to chop or slice fresh onions. They are especially useful in recipes where a subtle onion flavor is desired, or when fresh onions aren't available. They rehydrate quickly when added to liquids or can be sprinkled directly onto dishes for a crunchy texture and rich taste.
