How Do You Crisp Up Onion Rings?
To crisp up onion rings, first soak them in cold water for at least an hour to remove excess starch. Then, coat them in flour, dip them in an egg wash, and coat them in breadcrumbs or panko. Heat oil in a deep fryer or skillet to around 375°F and cook the rings in batches until they are golden brown and crispy. Remove them from the oil and place them on a paper towel-lined plate to drain excess oil. Serve immediately for the best texture.
