Frequently Asked Questions About Fried Red Onion
What is fried red onion used for?
Fried red onion is used as a crunchy topping for burgers, tacos, salads, soups and rice dishes. Add it just before serving so steam from hot food does not soften the pieces; it can also be served as a side with grilled food.
How do you make fried red onion crispy?
To make crispy fried red onion, slice the onion evenly, pat it completely dry and fry small batches in hot oil. Remove the slices as soon as they turn golden and drain them in a single layer rather than piling them up.
Can you make fried red onion in an air fryer?
Yes, fried red onion can be made in an air fryer. Toss thin slices with a little oil, spread them in a single layer and shake the basket occasionally. Check frequently near the end because thin onion slices can go from browned to burnt quickly.
What is the difference between fried red onion and onion rings?
Fried red onion is usually made from thin onion slices fried without a thick coating, so the result can be light and crisp. Onion rings are thicker rings, commonly dipped in batter or breadcrumbs before frying, giving them a substantial crunchy coating.
Why does fried red onion taste bitter?
Fried red onion tastes bitter when its sugars and thin edges burn in oil that is too hot or during overly long cooking. Fry the slices in small batches, watch their color closely and take them out when golden rather than dark brown.
Can you prepare fried red onion ahead of time?
Yes, you can prepare fried red onion ahead, but it is crispest when served soon after cooking. Cool it fully before storing it in an airtight container in the refrigerator, then briefly reheat it in an oven or skillet before serving.
Can you freeze fried red onion?
Yes, fried red onion can be frozen, though freezing may reduce its crispness. Let it cool completely, freeze it in a sealed container, and reheat the pieces straight from frozen in an oven or skillet instead of thawing them first.
Which red onion works best for frying?
Firm red onions with dry, unblemished skins are the best choice for fried red onion because they are easier to slice evenly and hold their shape. Avoid soft onions or ones with damp spots, which may cook unevenly.
Should you soak red onions before making fried red onion?
No, soaking is not necessary when making fried red onion, and wet slices can splatter in hot oil. If you soak the onion to mellow its sharpness, drain it thoroughly and pat every slice dry before frying.
Is fried red onion the same as French fried onions?
No, fried red onion is not necessarily the same as packaged French fried onions. Fried red onion simply describes red onion cooked in oil, while many packaged crispy onions are coated, made with other onion varieties or prepared with additional ingredients.

What is Fried Red Onion?
Fried Red Onion is made by slicing red onion and frying it until the edges turn crisp and the centre softens. Cooking mellows the onion’s sharpness and brings out a gentle sweetness. It can be prepared in a pan at home or bought ready to use, and the cut may range from thin slices to rings.
In many places, it is added to burgers, sandwiches, salads and grain bowls for crunch, or served as a side. Frying makes it more energy-dense than fresh onion, while it still contributes some fibre. Use it as a punchy topping rather than the main part of a meal; for a lighter homemade version, fry with a little oil and drain well before serving.
