Onion Rings Recipe

Slice and separate

Peel the onions and trim the stem ends. Slice each onion into 1/4- to 1/2-inch thick rings. Gently separate the slices into individual rings. If some rings remain attached, cut through the membrane to separate.

For crispier, less-soggy rings (optional): soak the separated rings in ice water for 15–30 minutes, then drain thoroughly and pat very dry with paper towels. Excess moisture prevents proper batter adhesion.

Mix dry ingredients

In a large bowl, whisk together 1 cup all-purpose flour, 1/4 cup cornstarch, 1 teaspoon baking powder, 1 teaspoon salt, 1/2 teaspoon black pepper, and 1/2 teaspoon paprika until evenly combined.

Combine wet ingredients

In a separate bowl, beat 1 egg lightly, then whisk in 3/4 cup milk. If using sparkling water for a lighter batter, measure 1/2 cup and keep it cold in the fridge until ready.

Make the batter

Create a well in the dry ingredients and pour in the egg-milk mixture. Stir until just combined; a few lumps are fine. If the batter is very thick, stir in up to 1/2 cup cold sparkling water a little at a time until the batter reaches a thick but pourable pancake-batter consistency that will coat rings (should fall from a spoon in a ribbon). Do not overmix.

Prepare dredging and coating stations

Place 1/2 cup flour in a shallow dish for dredging. Place the batter in a second shallow bowl. Place 1 cup panko breadcrumbs (or fine dry breadcrumbs) in a third shallow dish. Set up the stations in order: flour, batter, breadcrumbs.

Dredge each dry onion ring lightly in flour, shaking off excess. Dip the floured ring into the batter, letting excess drip off. Then press it into the breadcrumbs to coat evenly, turning to completely cover. For a thicker crust, double-dip by returning to the batter and breadcrumbs once more. Place coated rings on a wire rack while you finish coating the rest.

Heat oil

Pour enough oil into a deep skillet or pot to reach about 1 to 1 1/2 inches deep (about 1 to 2 cups depending on pan). Heat oil over medium-high heat until it reaches 350°F (175°C). If you don't have a thermometer, test by dropping a small bit of batter: it should sizzle and float immediately without browning too quickly.

Fry onion rings

Working in batches (do not overcrowd), gently lower a few coated rings into the hot oil with tongs or a slotted spoon. Fry for about 2 to 3 minutes per side, turning once, until golden brown and crisp. Total frying time will be about 4–6 minutes per batch depending on thickness. Adjust heat as needed to maintain 325–350°F; if oil is too hot they will brown outside before cooking through.

Drain and season

Use a slotted spoon to transfer fried rings to a wire rack set over a baking sheet or onto paper towels to drain. Immediately sprinkle with finishing salt to taste while still hot so it adheres.

Serve hot with your choice of dipping sauces (ketchup, ranch, spicy mayo) and enjoy.
