I used to grab the canned stuff, but these crispy fried onions are so golden, crunchy, and addictive that I may never go back. Homemade French’s fried onions have serious topping power, and yes, they work as air fryer onion rings too!
I’m obsessed with crispy fried onions because they hit every craving at once: crunchy, salty, a little sweet, and dangerously snackable. I love the way yellow onions turn bold and crackly under that golden coating, especially with a little smoked paprika in the mix.
And I don’t need a casserole as an excuse. I pile them on burgers, crush them over salads, swipe them through dip, or just eat them straight from the tray like I have zero self-control.
But honestly? Homemade tastes so much better than the canned stuff.
Bigger crunch. Fresher flavor.
Total onion-ring energy, without the crumbs.
Ingredients
- Yellow onions turn sweet inside, with those crispy edges everyone grabs first.
- Flour gives the coating body, so it actually sticks and fries up crunchy.
- Cornstarch is the crunch booster.
Basically, it keeps things light, not bready.
- Baking powder helps the batter puff a little, so you get that crackly bite.
- Salt wakes everything up, then a tiny finish makes them snack-level good.
- Black pepper adds a little warmth without taking over the onion flavor.
- Garlic and onion powders make the coating taste savory, not flat.
- Paprika brings color and a soft smoky vibe, if you use smoked.
- Egg helps the batter cling, so fewer sad, naked onion rings.
- Milk or buttermilk makes the coating tender.
Plus, buttermilk adds tang.
- Frying oil gives the big crunch, while oil spray works for air fryer days.
Ingredient Quantities
- 2 large yellow onions (about 1 pound), peeled and cut into 1 1/4 to 1 1/2 inch rings
- 1 cup (120 g) all purpose flour
- 1/2 cup (60 g) cornstarch
- 1 teaspoon baking powder
- 1 teaspoon fine salt, plus extra to finish
- 1/2 teaspoon freshly ground black pepper
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/4 teaspoon smoked paprika or regular paprika
- 1 large egg
- 3/4 cup (180 ml) milk or buttermilk
- Vegetable oil or peanut oil for deep frying, about 2 to 4 cups depending on pot size
- Neutral oil spray for air fryer use (canola or avocado oil)
How to Make this
1. Separate onion into 1 1/4 to 1 1/2 inch rings and soak in cold water 10 minutes, then pat dry thoroughly with paper towels.
2. Whisk together 1 cup flour, 1/2 cup cornstarch, 1 teaspoon baking powder, 1 teaspoon fine salt, 1/2 teaspoon black pepper, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder, and 1/4 teaspoon paprika in a shallow bowl. Reserve 1/4 cup of this dry mix for dredging.
3. In another bowl whisk 1 large egg with 3/4 cup milk or buttermilk until smooth, then stir in the remaining dry mixture to form a thick batter; adjust with a splash more milk if too thick.
4. Heat 2 to 4 cups vegetable or peanut oil in a deep pot to 350 to 375°F (175 to 190°C), or preheat air fryer to 400°F (200°C) and have neutral oil spray ready.
5. Toss onion rings lightly in the reserved 1/4 cup dry mix to coat and shake off excess.
6. Dip the dredged rings into the batter, letting excess drip back into the bowl, then carefully place into the hot oil in small batches so they do not stick together.
7. Fry rings 2 to 4 minutes, turning once, until deeply golden and crisp; do not overcrowd the pot. Use a slotted spoon to transfer to a paper towel lined tray and season with extra salt while hot.
8. For an air fryer method, arrange battered rings in a single layer in the basket without overlap, spray lightly with neutral oil, cook 8 to 12 minutes until golden and crisp, flipping and spraying again halfway through.
9. Keep finished rings warm on a baking sheet in a 200°F (95°C) oven if making multiple batches, and finish each batch with a sprinkle of fine salt to taste.
10. Serve immediately for best crispness or cool completely and store in a paper bag to retain crunch.

FAQ
Crispy Fried Onions Recipe Substitutions and Variations
- All purpose flour: use a 1-to-1 gluten free baking blend for gluten free crispy coating, or use rice flour for extra light crunch
- Cornstarch: substitute arrowroot powder or potato starch for similar crisping and light texture
- Large egg: use 3 tablespoons aquafaba or 1 tablespoon ground flaxseed mixed with 3 tablespoons water as vegan binders
- Milk or buttermilk: swap with unsweetened plant milk plus 1 teaspoon vinegar or lemon juice to mimic buttermilk, or thin plain yogurt with water to similar consistency
Pro Tips
1. Chill the onions before battering. A short time in the fridge after patting them dry firms the rings so the batter clings better and you get fewer floppy pieces.
2. Double texture trick: after the first quick fry or an initial 3 minute air fryer cook, rest the rings briefly, then finish for a minute more. That extra stage sets the crust and yields a lighter, crispier bite.
3. Control oil temperature with a thermometer and small test pieces. If the oil is too hot the coating will brown before the onion cooks; too cool and the batter soaks up oil. Adjust heat to hold about 350 to 375°F for frying, or stick to the recommended air fryer temp and avoid overcrowding.
4. Flavor lift at the end. Toss hot rings with a pinch of flaky salt and, if you like, a very small sprinkle of finely grated Parmesan or a dusting of smoked paprika right after frying. The salt sticks better when applied while the crust is still hot.
