Onion Ring Recipe

Peel and slice

Peel the onions and slice into 1/4- to 1/2-inch thick rings. Separate the slices into individual rings and set aside. If some rings remain attached, gently pry them apart with your fingers.

Soak (optional for milder onion)

If you prefer milder, less sharp onion rings, place the separated rings in a bowl of cold water for 10 minutes, then drain and pat dry on paper towels. Drying thoroughly helps the batter adhere.

Combine dry ingredients

In a medium 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 distributed.

Add wet ingredients

Whisk in the egg until blended. Gradually pour in about 1 cup of cold sparkling water or cold beer while whisking until you have a smooth batter with the consistency of heavy cream (thicker than pancake batter but still fluid). Do not overmix; a few small lumps are fine. Keep the batter cold while frying (place bowl over an ice bath if needed).

Prepare dredge and breadcrumbs

Place 1/2 cup all-purpose flour in a shallow plate for dredging. If using breadcrumbs or panko, spread 1/2 cup on a separate plate. This sequence (dredge → batter → breadcrumbs) creates a thicker, crispier coating.

Dredge rings

Lightly dust each onion ring in the dredging flour, shaking off excess. Immediately dip the floured ring into the cold batter, allowing excess batter to drip off, then press it into the breadcrumbs (if using) to coat. Place coated rings on a wire rack while the oil heats. If you prefer a simpler method, you can skip breadcrumbs and only dredge and batter.

Heat oil

Pour oil into a heavy-bottomed pot or deep skillet to a depth of about 1 to 1 1/2 inches (about 1 cup may be enough for a smaller pan). Heat oil over medium-high heat to 350°F (175°C). If you don't have a thermometer, test by dropping a small dollop of batter into the oil — it should sizzle and rise to the surface within a few seconds without browning immediately.

Fry in batches

Working in small batches (do not overcrowd), gently slide coated rings into the hot oil. Fry for 2 to 3 minutes per side, turning once, until the coating is golden brown and crisp. Use a slotted spoon or spider to transfer rings and allow excess oil to drain. Maintain oil temperature between 325–350°F (160–175°C); adjust heat as needed.

Drain and season

Transfer fried onion rings to a wire rack set over a baking sheet or to paper towels to drain briefly. While still hot, sprinkle with about 1 teaspoon kosher salt (or to taste) and an optional 1/4 teaspoon freshly ground black pepper.

Let the onion rings rest for 1–2 minutes briefly to set the coating, then serve immediately with ketchup, ranch, aioli, or your preferred dipping sauce. For best texture, eat within 15 minutes; if making ahead, re-crisp in a 375°F (190°C) oven for 3–5 minutes.
