Crispy fried onions can be deep fried in oil or you can make air fryer onion rings too! Want homemade French’s fried onions, they’re way better than canned!
I think I could put crispy fried onions on just about every casserole I make! Making them homemade was new this year and I couldn’t believe how easy they were! Either fried or made as thin air fryer onion rings and crushed turn a good dish into something incredible I tell you. (affiliate links present)
- Let’s start with the traditional method of making crispy fried onions on your stovetop first.
This is what you will need. It’s not much, and quite inexpensive to make too. Whether you want them as a sinful snack, or to top your Instant Pot green bean casserole, homemade is always best.
Yes you can buy a can of French’s fried onions to shake on top of your green bean casserole this year, but wait!!
- Try something new this year and make these onion straws instead!
There are many types of onions out there, but I think yellow are best for this. Can you use white onions for onion rings? This is purely up to you. White onions have a shaper, more pungent flavor, while yellow onions have a nice balance of sharp and sweet.
- Onions – sliced thin
- Vegetable oil for frying
- Shallow bowl
Yes we are going to slice them thinly for this recipe because for the most part you’re using them to top another dish. Little bite size crispy fried onions is what we want.
- The smaller you slice them the crispier and faster they will cook. Keep that in mind when preparing
For example, for our easy green bean casserole I like them REALLY crispy and teeny tiny in size. If I’m making these just to snack on I will slice them a bit thicker, more like homemade onion rings.
Steps are basic: Just put flour mixture in a bowl to combine, dip onion into buttermilk, then into flour, fry and drain on paper towels!
What is onion ring batter made of?
Typically it’s a mixture of flour and a liquid like buttermilk here with some salt and pepper for flavor.
What does soaking onions in ice water do?
- Some people soak their raw sliced onions in a bowl of ice water for 1 hour. Then they drain the liquid out and pat dry with paper towels before battering them.
- This tends to keep the onions crispier I think.
- It also reduces their pungency.
Once you’re ready you’ll want to prepare your oil for frying.
Tip: Do not put them in until it is nice and HOT. I drop a bit of batter inside the hot oil and if it immediately bubbles and cooks it is ready.

Crispy Fried Onions
- Line a large plate with paper towels and set aside. Pour oil into a cast iron pot and heat up to 375F in oven while you prepare the ingredients (if you're using cast iron, if not then skip this step and heat oil in med. frying pan over med. heat).
- Peel and slice off the top and bottom from the onion. Thinly slice to about 1/8th inch round slices. Mix the salt and pepper into the flour until well combined and pour the milk into a small bowl.

milk. Next dredge them in the flour also making sure they’re throughly coated.

both sides, this will take about 2 to 3 minutes on each side. Remove the onion
