These crispy beer battered onion rings have a light, golden coating with just a hint of spice. The carbonation in the beer creates an airy, crunchy batter that rivals any pub. Perfect as a snack, appetizer, or side dish for burgers and sandwiches.

Instructions
Heat vegetable oil to 375°F in a large Dutch oven or deep cast iron pot. Make sure oil is at least 2 inches deep. Use a thermometer to monitor the temperature throughout cooking.
Cut off the ends of the onions and remove the skin. Slice into ½-inch thick rounds and carefully separate into rings.
Place 1/2 cup of flour in a shallow bowl for dredging. Dust each onion ring in the flour and shake off excess.
In a large bowl, whisk together remaining 2 cups flour, salt, and cayenne pepper (if using). Pour in the beer and whisk gently until just combined. A few lumps are fine. Avoid overmixing.
Working in batches of 3 to 4 rings, dip the floured onion rings into the batter and coat well. Let excess batter drip off, then gently place in the hot oil.
Fry for 3 to 4 minutes total, flipping halfway through, until deep golden brown on both sides. Transfer to a wire rack set over a baking sheet to drain.
Keep cooked onion rings warm in a 170°F oven while frying remaining batches. Let oil return to 375°F between batches.
Notes
Oil depth: Make sure oil is at least 2 inches deep in your pot for proper frying.
Oil temperature: Maintaining 375°F is key. Too cool and the rings absorb oil and turn greasy. Let oil recover between batches.
Cayenne pepper: Optional, but adds a nice subtle heat. If omitting, add 1/2 teaspoon black pepper instead.
Onion varieties: Large Vidalia, yellow, or white onions all work well. Choose the biggest onions you can find.
Don't overmix: A few lumps in the batter are fine. Overmixing develops gluten and makes the coating tough.
Beer substitute: Plain club soda or seltzer water works if you prefer not to use beer.
Why flour first: Dredging in flour before battering helps the coating stick. Don't skip this step.
Drain on a wire rack: Paper towels trap steam and make the coating soggy. A wire rack keeps them crispy.
Keep warm: Place cooked rings on a wire rack in a 170°F oven while frying batches.
Storage: Refrigerate leftovers up to 2 days. Reheat in a 375°F oven or air fryer until crispy.
Freezing: Freeze cooled rings in a single layer, then transfer to a freezer bag. Reheat from frozen at 375°F.
