Onion Rings Recipe

Peel the large yellow onion and cut off the stem ends. Slice the onion into 1/4-inch thick rings. Gently separate the slices into individual rings and discard the small inner pieces if desired. Place the rings in a single layer on a paper towel-lined tray and pat them dry to remove excess surface moisture (5 minutes).

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

In a separate small bowl, lightly beat 1 egg. Add the beaten egg to the dry mixture and pour in 3/4 cup cold beer (or cold sparkling water). Whisk until a smooth, slightly thick batter forms. The batter should coat a spoon but still be pourable; if it's too thick, add 1 tablespoon cold water; if too thin, add 1 tablespoon flour.

Place the batter in the refrigerator to rest for 10 minutes while you heat the oil and prepare dredging stations. Resting helps improve texture and crispness.

Set up three stations: a shallow bowl with 1/2 cup flour for dredging, a bowl with the chilled batter, and a shallow plate with 3/4 cup breadcrumbs (or panko). Lightly dust a baking sheet or tray with a little flour to hold coated rings before frying.

Working in batches to avoid overcrowding, toss a few onion rings in the flour to coat lightly, shaking off excess. Dip the floured ring into the batter, allowing excess to drip back into the bowl, then press it into the breadcrumbs to coat (for single-coating crispness). Place the coated rings on the prepared tray in a single layer.

Pour about 6 cups vegetable oil into a deep, heavy-bottomed pot or deep fryer. Heat the oil to 350°F (175°C). If you don’t have a thermometer, test by dropping a small pinch of batter into the oil — it should sizzle and float steadily and take about 45–60 seconds to turn golden.

Carefully lower 6–8 coated onion rings into the hot oil (do not overcrowd). Fry, turning once if needed, until golden brown and crisp, about 2.5–3.5 minutes per batch depending on thickness. Use a slotted spoon or spider to remove rings and drain over the pot for a few seconds.

Transfer the fried rings to a wire rack set over a sheet pan or to paper towels to drain. Immediately season lightly with finishing salt while still hot to help it adhere. Repeat with remaining rings, allowing oil to return to temperature between batches.

Let the onion rings rest 1–2 minutes to cool slightly; they will crisp further as they cool. Serve hot.
