In a shallow bowl, whisk the first 5 ingredients. Separate onion slices into rings. Dip rings into batter. In a deep-fat fryer, heat 1 in. of oil to 375°. In batches, fry onion rings until golden brown, 1 to 1-1/2 minutes on each side. Drain on paper towels. Serve immediately.
I love the thick, beer-battered style of onion ring. But since I never deep fry at home, and they must be consumed immediately or they turn to lead, they are a very rare treat.
I like mine very thinly sliced with a light tempura batter. Must be consumed within less than minutes out of the oil. I always made my own, and used my wok to deep fry them. But I don’t make them anymore and I don’t order them in restaurants.
I too love them thin and crispy and hot out of the fryer. My favorite place changed hands, and their onion rings changed. Lost forever. So I have them out occasionally, but I’m mostly disappointed. I never fry at home, it’s just too messy before and after!
I used to love those “loaves” of onion rings that some restaurants would make by pressing thin-sliced and battered onions in a fryer basket and and then weighing them down with another basket. The thick-sliced ones I’ve tried lately seem like mostly ring and not much onion. Not that I wouldn’t eat some of those right now.
Gave away our deep fryer many years ago. Too hard to clean and took too much space. I just saw one recently that can completely disassemble for easier cleaning.
IIRC those deep fried onion loaves originated at Tony Roma’s. A chain restaurant. All the rage back then.
I gave away my deep fryer years ago. Frying onion rings in a large fry pan is too much of a hassle. The large rings take up too much room and it takes forever to cook a batch. I’ll stick to Dairy Queen. Good onion rings. And they don’t stink up the house.
