Instructions

1
Step 1: Slice the onions into 1/2-inch rings and separate into individual rings. Pat dry with paper towels to remove excess moisture.
2
Step 2: In a bowl, combine buttermilk and egg; whisk until smooth. Add the onion rings to the buttermilk mixture and let sit for 10 minutes to tenderize and flavor.
3
Step 3: In a shallow dish, whisk together flour, cornstarch, baking powder, salt, black pepper, paprika, and cayenne (if using).
4
Step 4: Place panko breadcrumbs in a separate shallow dish. Remove onion rings from the buttermilk, letting excess drip off, and dredge each ring in the flour mixture, tapping off excess.
5
Step 5: Return each floured ring briefly to the buttermilk (for a light double-dip) and then press into the panko, ensuring an even coating. Set coated rings on a wire rack while you heat the oil.
6
Step 6: Heat vegetable oil in a deep, heavy-bottomed pot to 350°F (175°C). Use a thermometer to maintain temperature. Do not overcrowd the pot—fry in batches of 6–8 rings.
7
Step 7: Fry rings 2–3 minutes per side until golden brown and crisp. Use a slotted spoon to transfer to a paper towel-lined tray to drain. Keep warm on a baking sheet in a 200°F (95°C) oven if needed.
8
Step 8: To make the dipping sauce, whisk together mayonnaise, ketchup, Dijon, lemon juice, and smoked paprika. Adjust seasoning to taste.
9
Step 9: Serve hot with the dipping sauce. For a lighter method, bake at 425°F (220°C) on a parchment-lined sheet sprayed with oil for 12–15 minutes, flipping halfway, or air-fry at 390°F (200°C) for 8–10 minutes.

💡 tips

For extra-crispy rings, double-coat: flour, buttermilk, flour, then panko. Keep the oil temperature steady—too cool yields greasy rings, too hot browns the exterior before the onion cooks. Use sweet onions for milder flavor and slice rings uniformly for even cooking.
