Onion Rings Recipe

Prepare onions

Peel the onions and slice into 1/4- to 1/2-inch thick rings. Separate into individual rings and set aside. For best results, separate rings gently so they remain intact.

Place the rings in a bowl of cold water for 10 minutes to reduce strong onion bite and help crispness, then drain and pat very dry with paper towels. Moisture will cause oil spattering and soggy coating.

Make dry mix

In a large bowl whisk together the all-purpose flour, cornstarch, baking powder, paprika, garlic powder, onion powder, salt, and black pepper until evenly combined.

Combine wet ingredients

In a separate small bowl whisk the cold beer (or sparkling water) and the egg until frothy. Cold liquid helps create a light, airy batter.

Pour the wet mixture into the dry mix and whisk just until combined. The batter should be thick enough to coat the back of a spoon but still slightly lumpy — avoid overmixing to keep it light. If using panko, place panko in a shallow dish for dredging.

Heat oil

Pour oil into a deep, heavy-bottomed pot or deep fryer to a depth of about 2–3 inches (roughly 1–1.5 cups depending on pot size). Heat to 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.

Coat and dredge

Working in batches (do not overcrowd), dust onion rings lightly with a little extra flour (use from the batter mix or separate 2 tbsp flour) to help batter adhere. Dip each ring into the batter to fully coat, letting excess drip off briefly. For extra-crunchy rings, immediately dredge the battered ring in panko breadcrumbs, pressing gently to adhere.

Fry until golden

Carefully lower a few rings into the hot oil using a slotted spoon or tongs. Fry for 2.5–3.5 minutes, turning if necessary, until they are deep golden-brown and crisp. Maintain oil temperature around 350°F; adjust heat to prevent burning or undercooking.

Use a slotted spoon to transfer cooked rings to a wire rack set over a baking sheet or to paper towels to drain. Immediately sprinkle with kosher salt to taste.

Repeat with remaining rings, allowing oil to return to temperature between batches. If using panko, fry slightly fewer rings at a time so the breadcrumbs don't clump.

Serve the onion rings hot with your preferred dipping sauce. For best texture, eat within 15 minutes of frying. Leftovers can be reheated in a 400°F (200°C) oven or air fryer for 4–6 minutes to re-crisp.
