“Crispy, old-fashioned buttermilk fried onion rings! Easy recipe full of Southern-style flavor”

Watch me make these Crispy Buttermilk Onion Ring from start to finish!

Apparently, I’m on a buttermilk kick! Last week it was this old-fashioned buttermilk pie and now today I’m coming at you with these extra crispy buttermilk onion rings. It wasn’t intentional but I’m certainly not complaining because these onion rings completed my turkey burger lunch like a champ!

When it comes to a fried side dish onions rings usually aren’t my first choice. I’m more of a french fries or hush puppies kinda chick, but every now and then it’s good to switch things up a bit. I had these GORGEOUS sweet onions just waiting for me to turn them into a beautiful dish. I attempted a blooming onion. It never bloomed. Then I thought I’d try this new fried onion strings recipe..yeah they were more like onion noodles.

After a second fail, I said screw it! Onion rings it is!!! I know onion rings. I can do onion rings. And like always these crisp buttermilk fried onion rings came out like pure perfection!

I’m telling ya, using crushed croutons is the way to go for extra crispy, flavorful onion rings. I usually use the butter flavored croutons but any flavor tastes great! I love the rosemary and cracked black pepper croutons.

Tips on Making The BEST Onion Rings

  1. Make Sure The Oil Is Hot. Before placing the onion rings into the oil make sure it is hot enough. I usually use one of the tiny discarded onion rings and do a test first. The oil will bubble and fry calmly when the tempt. is just right. If the oil is not hot enough you’ll have some soggy onion rings on your hand. If the oil is too hot the coating will brown before the onion is tender.
  2. Season The Batter. The batter is what your onions rings will taste like. Add seasonings to your liking but be easy on the salt if you also plan on salting them when they come out. I like my onion rings to be a bit on the sweeter, salty side.
  3. Use Good Oil. For cooking onions rings I like to use sunflower or peanut oil. Vegetable or Canola will work as well but can sometimes taste heavy.
  4. Drain On Cooling Rack. You want all the excess oil to drip off of the onion rings so place then on a cool rack for a crispy texture.

These buttermilk onion rings fry up so crispy and delicious!  You want to serve them piping hot for the ultimate crunch. They really can go with any dipping sauce but my favorite Mississipi Comeback Sauce!  Yum!!
