Whether you grow your onions or buy them, you can make your onion rings for just pennies a batch. Just simple ingredients – you don’t even need breadcrumbs. Don’t let the hot oil scare you. You can do this!

What You’ll Need

Vidalia, or sweet, onions are the best for these because of their flavor. But if you can’t find them, just soak regular onion in water for an hour before slicing them. For extra crispy onion rings, keep your slices thin. Thick slices will be softer. The evaporated milk will make the batter rich and creamy, but you can substitute buttermilk or cream if you need to.

For deep frying, a deep fryer is easiest and safer, but if you don’t have one you can use a Dutch oven. Peanut oil is best for frying but you can use vegetable oil too.

How to Make Deep Fried Onion Rings

Step One: Slice the Onions

Cut your onion into thick slices – about ¼ inch. Don’t go thinner or they’ll fall apart.

Step Two: Make Your Batter and Breading

Set up two bowls. In one, whisk together the eggs and evaporated milk. In the other, mix your flour with a good pinch of salt and pepper.

Step Three: Bread the Rings

Now here’s the thing – dip each onion ring in the wet stuff first, then coat it REALLY well in the flour. Like, press it in there. Don’t be shy about it.

Step Four: Heat the Oil

Heat your oil to 350°F. Use a thermometer – guessing doesn’t work here. While it’s heating, turn your oven to 200°F so you can keep the first batch warm.

Step Five: Fry Those Rings

Drop a few rings in at a time. Don’t crowd them or they’ll steam instead of fry. Cook for 3-5 minutes, flipping them once, until they’re golden brown.

Step Six: Keep Them Warm and Serve

Pull them out with a slotted spoon and drain on paper towels. Pop them in that warm oven while you fry the rest. Serve them HOT. Cold onion rings are just sad.

Storage Instructions

Once cooled completely, store your leftovers in an airtight container lined with paper towels in the fridge for up to four days. 

For best results, reheat the cooked onion rings in an air fryer, or in the oven. It will crisp them up nicely again.

Questions and Troubleshooting

Do you need breadcrumbs for onion rings?

Nope! These are super crispy with just a classic breading. Flour is all you need.

Can I make these in the oven or air fryer?

You can, but they won’t be the same. 

Can I use a skillet to deep fry?

Yes, absolutely! Just be careful because it’s more likely to spill and splatter.

What’s the best way to keep the onion rings crispy after frying?

Place the onion rings on a wire rack over a baking sheet lined with paper towels. This allows air to circulate and prevents them from getting soggy. Keeping them in a warm oven at 200 degrees F until ready to serve also helps maintain their crispiness.

Instructions
 

  • Slice the onion. Carefully slice the onion into ¼-inch slices.
  • Make the batter and breading. Add the eggs and evaporated milk to a medium bowl and mix well. Add the flour to another medium bowl and season well with salt and pepper.
  • Bread the onion rings. Soak onion rings in the batter, then dredge in the flour until coated well. Repeat with a handful of the rings.
  • Heat the oil. Add the oil to a heavy-bottomed Dutch oven or deep skillet and heat to 350°F. Check the oil temperature with a candy or instant-read thermometer. Preheat oven to 200℉ to keep onion rings warm after frying.
  • Fry. Carefully drop a few onion rings into the hot oil. Fry for 3-5 minutes, turning as needed, until golden brown. Remove with a slotted spoon and place on a paper towel-lined plate to drain. You'll need to fry in 4-5 batches.
  • Keep warm and serve. Keep warm in a 200℉ oven while you continue cooking the rest of the onion rings. Serve immediately.

Notes

It’s best to use a sweet onion like Vidalia, but if you can’t find one, soak your onion slices in water for an hour before breading.
