These thin and crispy Crispy Onion Rings are perfect for burgers, as a side dish, or even as a snack! You might want to double the recipe though – they’re addicting! You have to wonder how something so simple can be so darn good.
Place the onion rings in a container. Pour buttermilk over the top. Cover with plastic wrap and allow to sit for at least an hour.
In a separate shallow dish (such as a pie plate), combine the flour with salt and pepper.
In a deep skillet or fryer, heat oil to 375°F.
Working in batches, take some of the onions from the buttermilk and coat in the flour mixture. Shake off excess flour and immediately place the onions in hot oil. Carefully mix the onions in the oil with a metal slotted spoon (to break them up) and allow to cook until golden brown. Remove onions from oil with a metal slotted spoon to a paper towel-lined plate. Repeat with remaining onion slices.
Serve immediately.
Notes
This recipe is very customizable if you want more flavor to your rings. Feel free to add paprika, garlic powder, ground black pepper, etc to your flour mixture. Sometimes I like to use Cajun seasoning!
No buttermilk?! No problem! In a pinch, regular milk with vinegar or lemon juice can be substituted for the buttermilk. Use 1 teaspoon of lemon juice or vinegar and fill the rest of the measuring cup with milk, then allow the mixture to stand for about 5 minutes before using.
