Onion Rings Recipe
Make crispy Onion Rings Recipe with a light, lacy batter and serve hot with spicy mayo.
Ingredients
- 2 large yellow or sweet onions (about 1 lb / 450 g total), peeled and sliced into 1/2-inch (1.25 cm) thick rings, inner membranes separated
- 2 cups (480 ml) very cold water, for soaking onion rings
- 1 1/2 cups (190 g) all-purpose flour
- 1/2 cup (65 g) cornstarch
- 2 teaspoons (8 g) baking powder
- 2 teaspoons (10 g) kosher salt, divided (1 teaspoon for batter, 1 teaspoon for finishing)
- 1 teaspoon (2 g) paprika (sweet or smoked)
- 1/2 teaspoon (1.5 g) garlic powder
- 1/4 teaspoon (0.5 g) cayenne pepper, optional, for a slight heat
- 1 large egg (about 50 g), at room temperature
- 1 1/4 cups (300 ml) very cold sparkling water or club soda
- 1/4 cup (60 ml) cold whole milk or buttermilk
- 6–8 cups (1.5–2 L) neutral oil with high smoke point, such as canola, peanut, or vegetable oil, for deep-frying
- 1/4 teaspoon (1 g) freshly ground black pepper, for finishing
- 2 tablespoons (8 g) finely chopped fresh parsley, optional, for garnish
- 1/2 cup (120 ml) ketchup, for serving, optional
- 1/2 cup (120 ml) mayonnaise, for serving, optional
- 1 tablespoon (15 ml) hot sauce or sriracha, for serving, optional, to mix with mayonnaise
Instructions
Step 1: Trim, peel, and slice the onions
Trim the root and stem ends off two large yellow or sweet onions, peel them and slice crosswise into 1/2-inch (1.25 cm) thick rounds. Gently separate each round into individual rings, set aside the very small centers for another use, and arrange the full rings in a shallow stack so they’re ready for the next step.
Step 2: Soak, drain, and dry the rings
Place the separated rings into a large clear glass bowl and cover with very cold water; let them sit for twenty minutes to mellow the bite and improve juiciness. After soaking, drain the rings and spread them out on a clean kitchen towel or paper towels, patting each ring dry until no visible surface water remains so the batter will cling evenly.
Step 3: Whisk together the dry mix
In a modern matte grey ceramic mixing bowl combine the all-purpose flour, cornstarch, baking powder, the first measure of kosher salt, paprika, garlic powder and cayenne (if using). Whisk briskly until the powdery textures are homogenous, the flour looks velvety and there are no lumps of seasoning — the bowl should show a fine, sandy crater where the whisk passed through.
Step 4: Make the wet mix and combine into batter
In a small glass bowl lightly beat the egg, whisk in the cold whole milk or buttermilk, then slowly add the very cold sparkling water while stirring just until smooth. Pour the wet blend into the grey mixing bowl over the dry ingredients and whisk gently until a silky, pourable batter forms — thick like heavy cream, with a few small, glossy lumps and a visible ribbon when lifted with a whisk. Chill the bowl briefly so the batter stays very cold.
Step 5: Prepare the frying station and test consistency
Set out a rectangular rimmed baking sheet topped with a wire rack for draining, position the chilled batter next to the drained onion rings, and place tongs and a slotted spoon nearby. Test one ring by coating and lowering it into hot oil; judge the batter by how it sizzles, rises and browns — adjust oil temperature or batter looseners as needed. The station should read as orderly: a batter-coated whisk resting on the grey bowl rim, a small glass jug of sparkling water nearby to refresh the batter if it thickens.
Step 6: Fry in small batches and drain to crisp
Working in restrained batches, dip rings in the cold batter so each ring is evenly coated, let excess drip back for a couple of seconds, then lower carefully into hot oil (maintain steady heat). After 2–4 minutes the exterior should be deep golden and lacy, the batter full of tiny bubbles and glassy crisp edges. Transfer each batch to the wire rack on the rectangular sheet to drain and rest; immediately season with the remaining kosher salt and a light dusting of freshly ground black pepper while still hot.
Step 7: Make dipping sauce and finish plating
If serving sauces, stir mayonnaise with hot sauce or sriracha in a small ceramic ramekin and set a separate small bowl of ketchup alongside; keep all liquids in vessels. Just before serving, scatter finely chopped fresh parsley over the hot rings for a burst of green and place the piled, golden onion rings on a rectangular matte white serving platter so they maintain the same geometric language as the draining sheet. Serve immediately while piping hot and crisp.
Notes
- Keep the batter very cold to ensure a light, lacy crust.
- Fry in small batches and allow oil to return to temperature between batches.
- Drain on a wire rack, not paper, to keep rings crisp.
- Use sparkling water or club soda for the best airy texture.
- If allergic to peanut, use canola or vegetable oil instead.
