Ingredients You’ll Need for Crispy Onion Rings

• 2 large sweet onions (Vidalia or Walla Walla)
• 1 cup all-purpose flour
• 1 cup cold sparkling water
• 2 cups panko breadcrumbs
• 1 teaspoon garlic powder
• 1 teaspoon paprika
• 1 teaspoon salt, plus more for finishing
• Vegetable oil, for frying
• Ketchup, ranch, or spicy mayo, for dipping

How to Make Onion Rings Crispy and Not Soggy

1. Peel the onions and slice into 1/2-inch rings, then separate them into individual rings.
2. In a shallow bowl, whisk together the flour, garlic powder, paprika, and salt.
3. Whisk in the cold sparkling water until you have a smooth, slightly thin batter.
4. Place the panko in a second shallow dish.
5. Heat 2 inches of vegetable oil in a heavy pot to 375°F.
6. Dip each ring into the batter, let the excess drip off, then press firmly into the panko to coat both sides.
7. Fry in batches for 2 to 3 minutes per side, until deep golden and crisp, without crowding the pot.
8. Drain on a wire rack, sprinkle with salt right away, and serve hot with dipping sauce.

Tips for the Crispiest Onion Rings

• Use ice-cold sparkling water, since the cold and bubbles create an extra light, crisp batter.
• Press the panko onto the rings firmly so the crust does not fall off in the oil.
• Keep the oil at 375°F; lower temperatures make greasy, soggy rings.
• Drain on a wire rack instead of paper towels so steam does not soften the bottoms.

Variations to Try

• Bake at 425°F on a wire rack for 15 to 20 minutes for a lighter version
• Air fry at 400°F for 8 to 10 minutes, spraying lightly with oil
• Add cayenne to the batter for spicy onion rings
• Swap panko for crushed cornflakes for an extra-crunchy crust

How to Store It

Onion rings are best eaten fresh. Store leftovers in an airtight container in the fridge for up to 2 days, then reheat in a 425°F oven or air fryer for 5 to 8 minutes to re-crisp.

To freeze, flash-freeze coated, unfried rings on a tray, then transfer to a freezer bag for up to 2 months and fry or bake from frozen.

Frequently Asked Questions

What kind of onion is best for onion rings?

Sweet onions like Vidalia or Walla Walla are best because they are mild and tender, but yellow onions also work.

Why are my onion rings soggy?

The oil may not be hot enough, the pot may be crowded, or they were drained on paper towels instead of a wire rack. Keep oil at 375°F and fry in small batches.

Can I make crispy onion rings in the air fryer?

Yes. Spray the coated rings with oil and air fry at 400°F for 8 to 10 minutes, flipping halfway.

Why does the breading fall off my onion rings?

Press the panko firmly onto the battered ring, and avoid moving them around in the oil until the coating sets.
