👥 Serves: 5
⏳ Prep Time: 10 minutes
🔥 Cook Time: 8 minutes
🥕Main Ingredients: Onions, flour, spices
🍳 Special Equipment: Cast iron skillet
⭐ Why You’ll Love It: Light crisp batter that fries up golden every time. The onion turns soft and sweet in the center.
Why Make Them?
- Texture: The outside crunch. But in contrast with the crunch is the silky, juicy texture of the onion.
- Flavor: Ordering onion rings out is usually a disappointment. They never have the texture you crave. Making them at home is faster and easier than ordering takeout, and there is no comparison in flavor.
- Ease: All you have to do is measure and mix the dry ingredients and stir in the wet ingredients. Then, dredge, dip and cook the onion.
- A crowd pleaser: Everyone who tries these battered onion rings will love them.
- Just the right bite: The onions get tender with just a bit of bite, and the batter clings tightly so it doesn’t slide off when you take a bite.
How to Keep the Batter From Falling Off
The key to helping the batter stick to the slippery onion. is multi-fold. First, once the onion rings are separated, pat them dry with paper towels. This is important to remove excess moisture.
Next, dredge the onion rings in flour. Since the onions themselves are slick, you need an outer texture that will give the batter something to stick to.
Third, maintain the oil temperature throughout the cook. To aid this, don’t crowd the pan and don’t add too many to it at once. This will lower the oil’s temperature.
What You Need
- Onion: Use a large onion, yellow or white. Vidalia onions work well here, too.
- Flour: Any flour will work; all-purpose flour is ideal. It’s important to first dredge the rings in flour, so the batter has something to stick to.
- Cornstarch: Cornstarch is one of the secret ingredients that makes the most crispy fried foods.
- Garlic: Use garlic powder or granulated garlic.
- Onion Powder: Adds an earthy, slightly spicy flavor.
- Paprika: Paprika is made from ground, dried red peppers, so it adds a bit of spice.
- Chili Powder: A bit of chili powder adds a kick without making them spicy. If you’d like to add more, do so.
- Baking Powder and Baking Soda: These help the batter puff and stay light while adding crisp texture.
- Salt: Be sure to season the flour the onions are dredged in, and the batter with salt for the best flavor.
- Pepper: Again, season both the dredging flour and the batter.
- Carbonated Beverage: Instead of using water, use a carbonated beverage like beer (a lager or amber, not a stout), plain club soda, or seltzer. The bubbles create a lighter, crisp coating that keeps them from feeling heavy. Be sure that whichever you choose, the liquid is cold. This will also help with the puffiness.
- Oil: Use a neutral-flavored oil for frying.

How to Make Them

Measure the dry ingredients. Add them to a medium bowl. Mix well.

Slice the onions to your desired thickness. We aim for about ½-inch thick.

Separate the rings from the slices. Let the onions sit for a few minutes. Pat each ring dry on the cut end with a paper towel.

Season a separate bowl with salt and pepper for the dredge. Dredge the onion in the flour mixture.

Start a cast-iron skillet with oil heating over medium heat. Heat the oil to 375°F.

Once the oil reaches temperature, add the cold liquid to the bowl with the dry ingredients for the batter.
Whisk the batter just until combined. Don’t overmix it or you’ll lose crispness.

Shallow-fry the onion rings in the hot oil on one side until golden brown.

Flip them with tongs and fry the other side until golden. Drain on paper towels.
To keep the rings hot and crunchy when doing multiple batches, place the rack over a rimmed baking sheet and put the rings in a single layer in the oven at 200°F.
Frequently Asked Questions
Peanut oil is the best choice. If you don’t have peanut oil, use vegetable oil instead.
No. The batter will become very thick and pasty and won’t work well for subsequent batches.
Yes. A deep fryer will work well and eliminate the need to flip them.
No. Plain water will work, but carbonation produces a lighter, crispier coating.
It is best to make the batter immediately before you are ready to fry your onion rings so that the beer or club soda doesn’t lose all of its fizz.
While you can make them ahead and reheat them in your air fryer or oven, they have the best flavor and texture when made fresh.
No. This is a true batter-style recipe, so there’s no need for an egg dip. A light flour dredge helps the batter stick without making the coating heavy or slippery.
