- Prep the Onions: Slice the onion into ½-inch thick rounds. Carefully separate the rounds into individual rings.
- Heat the Oil: In a heavy-bottomed pot, heat about 2 inches of oil over medium-high heat until it reaches 350°F / 175°C.
- Coat the Rings (The "Double Dip" Hack): Working one ring at a time, first dredge it in the flour mixture, then dip it completely in the buttermilk, and finally dredge it back into the flour mixture for a thick coating.
- Fry Until Golden: Carefully place 3-4 coated rings into the hot oil. Do not overcrowd the pan. Fry for 2-3 minutes per side, until they are deep golden brown and crispy.
- Drain and Salt: Using tongs, remove the onion rings from the oil and place them on a wire rack to drain. Immediately sprinkle with salt while they are still hot. Serve immediately.
Notes
- The Ultimate Crispy Hack: The secret to a shatteringly crisp coating is the combination of cornstarch in the flour and using ice-cold sparkling water or beer for the batter. The cold liquid and the bubbles create a light, airy batter that fries up incredibly crunchy.
- Make the Batter Stick: The "double dip" method is key. Dredging the onion rings in the dry flour mixture before dipping them in the wet batter and again after gives the batter something to grip onto, so it won't slide off in the fryer.
- No Buttermilk? No Problem! If you don’t have buttermilk, you can easily make a substitute. Simply add one tablespoon of lemon juice or white vinegar to one cup of regular milk and let it sit for 5 minutes before using.
- Keep Them Crispy: To keep a large batch warm and crispy while you fry, you can place the finished onion rings on a wire rack in an oven preheated to 200°F (95°C).
- Storing & Reheating: Onion rings are best enjoyed fresh. To store leftovers, place them in an airtight container in the fridge. To bring back the crunch, reheat them in an air fryer or a hot oven at 375°F (190°C) for 5-7 minutes. Never use a microwave.
