Jump to RecipeA Story From My Kitchen
The night I made these crispy homemade fried onions, they were never part of the plan. I was deep into prepping a green bean casserole — because some dishes just aren’t complete without that iconic topping — when I realized I had no fried onions in the pantry. None. I called out for someone to run to the store, but that request went unanswered. So I did what any capable home cook would do.
I made them myself.
I peeled a yellow onion, sliced it thin, tossed it in a quick mix of flour and cornstarch, and dropped the strands into hot oil. And goodness gracious…The CRUNCH. The COLOR. The DISRESPECT these onions showed toward the store-bought kind. I ate half the first batch straight off the paper towel. The green bean casserole never stood a chance.
From that moment forward, I never bothered buying canister fried onions again. Once you taste these light, delicate, golden homemade crispy fried onions, the store-bought ones start to feel like the processed pieces they’ve always been.
And the best part? They make everything better — casseroles, salads, burgers, soups, baked mac and cheese (especially my Three-Cheese Macaroni), and whatever else is lucky enough to land on your plate.
Homemade vs. Store-Bought
Let me say this with love: store-bought fried onions had their time. They’re convenient, they’re fine in a pinch, and they helped many casseroles survive many holidays.
But homemade? Homemade is a different league. They’re lighter, crispier, fresher, and honestly — they just taste alive. They turn everyday dishes into something special, and once you make them yourself, you realize how quick and fun they are. No preservatives. Just pure, golden, crunchy goodness.
Ingredients You’ll Need
- 1 medium yellow or white onion
- 2 tablespoons all-purpose flour
- 1 tablespoon cornstarch
- ¼ teaspoon salt
- Black pepper to taste
- ¼ cup vegetable or canola oil for frying
- Paper towels for draining
How to Make Crispy Fried Onions
Time needed: 15 minutes
- Slice the Onions Thin
Peel your onion and slice it into thin, even strands — about ⅛ inch thick. Thin slices crisp beautifully and cook evenly without becoming chewy.
- Coat with Flour and Cornstarch
In a small bowl, whisk together flour, cornstarch, salt, and pepper. Add the sliced onions and toss gently until coated. Shake off any extra so the onions stay light and airy.
- Heat the Oil
Warm the oil in a large skillet over medium-high heat. You’ll know it’s ready when a single onion strand sizzles immediately on contact.
- Fry Until Golden and Crisp
Add the onions in a single layer — working in batches if needed — and fry for 3–5 minutes. Stir or flip gently until they turn evenly golden and crisp.
- Drain and Cool
Use a slotted spoon to transfer the onions to paper towels. Let them rest for a minute or two; they get even crispier as they cool.
FAQ: Crispy Fried Onions
Yellow onions are the classic favorite — perfectly sweet and savory when fried. White onions deliver a sharper flavor. Red onions taste great but lose their purple color when fried. Sweet onions become candy-sweet and delicious.
Truthfully? Use whatever onion is sitting in your pantry. Fried onions are forgiving.
Thin slices fry perfectly in 3–5 minutes over medium heat. Pull them when they turn golden — they continue crisping as they cool. If you wait until they look fully crisp in the pan, they’ll be too dark and taste bitter.
Cornstarch absorbs moisture and creates a delicate, glassy crispness — the same technique used in tempura and some Korean fried chicken. When combined with flour, it produces a coating that stays crunchy longer without feeling heavy.
Yes! Cool them completely, then store in an airtight container lined with a paper towel. They stay crisp for 1 day at room temp, or up to 3 days in the fridge. To re-crisp, heat them in a dry skillet or bake at 350°F for 3–5 minutes.
You can — but they won’t be as delicate. Toss lightly with oil and air-fry at 375°F for 10–12 minutes, shaking halfway through.
Absolutely. They lose most of their color, but the flavor? Chef’s kiss.
Make-Ahead, Storage, and Reheating
Store fried onions in an airtight container once fully cooled. Layer them with paper towels to keep moisture away. They’re best fresh but still delicious when re-crisped.
If you REALLY want them super crisp later, pop them under a broiler for 20 seconds — but watch closely.
