How to Make the Best Onion Rings in the Deep Fryer

Learning how to make the best onion rings in your deep fryer at home is easier than you might think.  If you live anywhere in the United States, you probably cannot count the number of hamburgers you have eaten in your life.  More often than not, you are eating French Fries as your side dish.  Another great dish that goes great with hamburgers, chicken sandwiches, or really any sandwich is homemade onion rings. 

Traditional Onion Rings versus Deep Fried Onion Straws

There are two main types of onion rings.  One type is a solid large ring with a thick onion in the middle.  The alternative, which is my preference, is a thin onion with a crispier coating on the outside that is more of an onion straw than an onion ring.  The ratio of breading to onion and the crispiness of this style is much more versatile.

How to Make a Simple Onion Ring Batter that Will not Fall Off

When making traditional thick cut onion rings, the batter typically will include flour, eggs, milk, bread crumbs, baking powder and seasonings.   When preparing thin onion straws, the "batter" is much simpler and just as flavorful and delicious.  It is basically just flour, salt, pepper, paprika and/or cayenne pepper.  The key to ensuring the batter will not fall off or become soggy lies in the preparation and frying technique. 

Buttermilk mixture for fried onion rings recipe

By soaking the onions in buttermilk for an hour before frying them, when you drop the onions into the flour mixture, the flour will cake on and form the batter.  As long as the onions are fully coated in the flour mixture after they were soaked, the batter will stick to the onion rings and not fall off.

Onion Rings in a Deep Fryer Not Soggy

Keep the onion rings from getting soggy by following these three tips:

  1. Make sure your oil is at temperature (350 degrees) prior to dropping the onion rings in.  You can test the temperature by dropping  a tiny amount of the batter into the oil to see if it immediately bubbles and starts to brown.
  2. Do not overcrowd your deep fryer.  If too many of the onion rings stick together, they will not cook properly and the coating on each ring will start to come off.  When the onions are evenly spaced, the coating will seal on the onions as they cook and will stay on to form a perfect crispy crust.
  3. Prepare a paper towel lined plate before beginning to fry the onion rings.  Once the onion rings are done frying, immediately transfer them to the plate so the paper towels will absorb the excess oil.  Just a note that this is a great opportunity to season the rings with salt and pepper before serving.

How to Make the Best Onion Rings in Your Deep Fryer

Crispy and delicious onion straws in 15 minutes using only a few ingredients!

Prep Time 5 minutes
Cook Time 10 minutes
Additional Time 1 hour
Total Time 1 hour 15 minutes


  • One Large White Onion
  • Pint of Butter Milk
  • 2 Cups Flour
  • Salt and Pepper
  • Cayenne or Paprika


  1. Peel the onion and slice it into rings, making each cut as thin as possible without the onion falling apart.
  2. Put onions in a shallow bowl or dish and pour buttermilk over them. Let the onion slices sit in buttermilk for at least one hour.
  3. Preheat your deep fryer to 350 degrees.
  4. While the onions are soaking, prepare the flour mixture. Pour two cups of flour into a zip lock bag and then add paprika, salt and pepper to taste. If you want the onion rings to have a little spice, add 1/8 tsp of cayenne pepper.
  5. After the onions have soaked, use tongs to drop the wet onions into the seasoned flour, after letting the extra buttermilk drip into the baking dish/bowl before putting them in the bag.
  6. Seal the bag with air and gently turn the bag over to shake the flour around to completely coat the onion rings. You want them to be somewhat clumpy so that the batter will stick when cooking.
  7. Once the deep fryer is at 350 degrees, drop the onion rings into the fryer in batches small enough that they do not overcrowd. If a few rings are sticking together, that is alright.
  8. After 5 minutes check the onion rings which should be done or close to done. They should be light golden brown and will continue to cook slightly once removed from the oil.
  9. Put the onion rings on a paper towel lined plate to dry and cool slightly. While the oil is still wet you should season with salt and pepper to taste.
  10. Serve with your favorite dipping sauce or on top of your favorite burger or sandwich!
