Beer-Battered Onion Rings

Cold lager gives a light crunch to thick sweet onion rings, fried in measured batches and served hot with ranch and spicy ketchup.

Golden beer-battered onion rings are piled on a platter beside ranch and spicy ketchup dips.

These onion rings are built for the familiar bar-and-grill platter: thick sweet onion, a crisp beer batter, and two straightforward dips. Drying the rings and keeping the lager cold help the coating stay light.

A thermometer and a heavy pot keep the frying pace controlled. Small batches give the batter room to brown evenly without driving the oil temperature down.

Start with dry, even rings

Cutting the onions into half-inch rounds gives each ring enough structure to hold its shape through dredging and frying. Pat the separated rings dry so excess moisture does not loosen the batter or make the oil spit.

Keep the lager batter light

The reserved flour gives the batter something dry to grip, while cornstarch helps the fried shell feel crisp rather than bready. Stir just until the dry pockets disappear; a few small lumps are preferable to a heavily worked batter.

Dry onion rings sit beside a bowl of cold lager batter and a shallow dish of flour before frying. — Dry onion rings are floured and dipped in cold lager batter just before frying.

Let the thermometer set the pace

Frying at 350 F helps the batter set quickly and brown before the onion softens too far. Adding only a few rings at once lets the oil recover between batches and keeps the crust from turning greasy.

Use the rack, then serve

An open rack lets excess oil fall away while air moves around the crust, so the underside stays crisp. The 200 F oven is only a short bridge between batches; bring the platter out promptly with ranch and spicy ketchup.

Keep frying calm and controlled

If the coating darkens before it turns crisp, pause and bring the oil back toward 350 F before adding another batch. Keep the pot less than half full, lower rings away from you, and leave hot oil alone until it has cooled completely.

Beer-Battered Onion Rings

6 appetizer servings

45 minutes total

Ingredients

• 2 large sweet onions
• 1 1/2 cups all-purpose flour, divided
• 1/3 cup cornstarch
• 1 tsp baking powder
• 1 tsp kosher salt, divided
• 1/2 tsp paprika
• 1/2 tsp freshly ground black pepper
• 1 large egg
• 1 cup cold lager beer
• 4 to 6 cups neutral high-heat oil, as needed for 1 1/2 to 2 inches in the pot
• 1/2 cup ranch dressing
• 1/2 cup ketchup
• 1 tsp hot sauce

Method

Cut and dry the onions
Peel the onions, slice them crosswise into 1/2-inch rounds, and separate into rings; discard the papery ends and pat every ring thoroughly dry with clean towels.
Look for: The rings separate cleanly and feel dry to the touch, with no moisture beading on their surfaces.
Set up the dips and holding rack
Stir the hot sauce into the ketchup, spoon the ranch and spicy ketchup into separate serving bowls, and set a wire rack over a rimmed sheet pan; heat the oven to 200 F for brief batch holding.
Look for: The dips are ready beside an open rack that allows air to circulate beneath the onion rings.
Heat the frying oil safely
Pour 1 1/2 to 2 inches of oil into a heavy pot, never filling it more than halfway, attach a thermometer, and heat over medium to 350 F; keep the pot stable and the area dry.
Look for: The thermometer holds near 350 F and the oil surface shimmers without smoking.
Mix the cold beer batter
Put 1/2 cup flour in a shallow bowl for dredging; whisk the remaining flour with cornstarch, baking powder, 3/4 tsp salt, paprika, and pepper, then whisk the egg and cold beer together and stir them into the dry mix just until no dry pockets remain.
Look for: The batter is cold, thick enough to cling, and lightly lumpy rather than heavily beaten.
Coat a few rings at a time
Working in small batches, toss dry onion rings in the reserved flour and shake off excess, then dip each ring in batter and let the extra drip back into the bowl before frying.
Look for: Each ring has a thin, even batter coat, and neighboring rings remain separate rather than stuck together.
Fry in small batches
Lower 3 or 4 coated rings into the oil at a time, moving the rings away from you, and fry for 2 to 3 minutes total, turning once, until golden and crisp; let the oil return to 350 F between batches and lower the heat if it rises above 365 F.
Look for: The coating turns an even golden brown, the bubbling slows, and the oil stays controlled without smoking.
Drain and season each batch
Lift finished rings with a spider or tongs, drain briefly over the pot, then arrange them in one layer on the rack and sprinkle with the remaining 1/4 tsp salt while hot; hold batches in the warm oven only as long as needed.
Look for: Oil drains back into the pot, the rack stays uncovered, and salt adheres while the coating is hot.
Serve while crisp
When all rings are fried, turn off the burner and serve them promptly on a warm platter with ranch and spicy ketchup; keep the hot pot in place until the oil has cooled completely and never add water to it.
Look for: The rings remain crisp at the edges and both dips are ready for serving.
