Recipe guide

Crispy onion chips use a light batter and panko for extra crunch. Ideal as a quick snack or side, especially with dips. This guide keeps steps practical and oven-free.

Crispy onion chips in minutes with a simple batter and panko crust.

  • Coat lightly, don’t overbatter
  • Maintain oil temp between batches
  • Salt immediately after frying for best crust

1) Prep and batter: mix, dredge, and coat with panko

Separate onion rings, pat dry, and season with salt and pepper. Make the batter by whisking flour, baking powder, paprika, cayenne (optional), remaining salt and pepper, then whisk in the beaten egg and cold sparkling water until smooth but not paste-thick. Dredge rings in dry flour, dip in batter, and press into panko. Fry in hot oil until evenly golden, 2–3 minutes per side. Drain on paper towels and salt lightly.

2) Frying: keep temp, avoid crowding, drain well

Maintain oil at 350°F/175°C and fry in batches to avoid overcrowding. Let oil return to temperature between batches. Fry until crisp and golden on both sides, then transfer to towels to drain. Serve warm with dips.

3) Serve: enjoy warm and crisp

Serve immediately with your favorite dip. If not serving right away, keep warm in a low oven for a few minutes to maintain crispness.

Ingredients

  • 2 medium onions, peeled and thinly sliced into rings
  • 1 cup all-purpose flour
  • 1 tsp baking powder
  • 1 tsp paprika
  • 1/2 tsp cayenne pepper (optional)
  • 1 tsp salt, divided
  • 1/2 tsp black pepper
  • 3/4 cup cold sparkling water
  • 1 large egg, beaten
  • 1/2 cup panko breadcrumbs (for extra crunch)
  • Vegetable oil for shallow frying (about 1/2–1 cup)

Instructions

  1. Separate onion rings into individual pieces and pat dry with a paper towel.
  2. Toss onion rings with 1/2 teaspoon salt and a pinch of pepper; let sit 5 minutes and re-pat dry if they release moisture.
  3. Heat about 1/4–1/2 inch of vegetable oil in a wide skillet over medium-high until shimmering (350°F/175°C if using a thermometer).
  4. Whisk flour, baking powder, paprika, cayenne (if using), remaining 1/2 teaspoon salt, and 1/2 teaspoon black pepper in a bowl.
  5. Stir in beaten egg and pour in cold sparkling water slowly, whisking until a smooth, slightly thick batter forms; batter should coat but not be paste-thick—add a splash more water if needed.
  6. Place panko breadcrumbs in a shallow dish.
  7. Working in batches, dredge onion rings lightly in dry flour mixture (to help batter adhere) then dip into batter, letting excess drip off, and press into panko for extra crunch.
  8. Carefully place coated rings into hot oil in a single layer without overcrowding.
  9. Fry until golden brown and crisp on one side, about 2–3 minutes, then flip and cook another 1–2 minutes.
  10. Transfer cooked chips to a paper-towel-lined plate and season immediately with a little extra salt.
  11. Let oil return to temperature between batches and repeat with remaining onions.
  12. Serve warm as a snack or side with your favorite dip.

FAQs

Can I fry larger batches or different onion sizes? Yes. You can skip the poke and keep to 350°F; adjust time for larger rings.
Can I use still water instead of sparkling water? Yes. Replace sparkling water with cold still water, though batter may be less airy.
How can I make them extra crispy? Yes. If you prefer thicker chips, increase batter or crust amounts slightly and fry a bit longer.
