Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Pearl onions (fresh or frozen, peeled)
All-purpose flour
Spices (paprika, garlic powder, cayenne, salt, black pepper)
Egg (for dredging)
Oil (for spraying/misting)

Directions

Partially cook or thaw the onions
- If using frozen pearl onions, microwave or briefly steam them to loosen the skins (e.g. 1–2 minutes) and then drain and pat dry.
- If fresh, trim ends and peel the outer skin.
Prepare the coating
- In one bowl, combine flour and spices (paprika, garlic powder, cayenne, salt, pepper).
- In another bowl, beat the egg.
- For a double coating effect, you may dredge: flour → egg → flour again. Coat the onions
- Work in small batches: first toss onions in the seasoned flour.
- Dip into the egg, letting excess drip off.
- Return to flour mixture for final coating.
Chill briefly
- Place the coated onions on a tray and refrigerate about 10 minutes. This helps the coating adhere. Preheat air fryer
- Preheat to 380 °F (≈ 193 °C) for a few minutes. Air fry
- Arrange onions in a single layer in the basket (don’t overcrowd).
- Lightly spray or mist with oil.
- Cook for 3 minutes, then open the basket, shake or turn, spray again, and continue for another 3 minutes until golden and crisp.
Serve immediately
- Serve while hot for best crispness.

Parmesan crust: Mix grated Parmesan with flour for extra flavor and crisp.
Balsamic glaze: After cooking, drizzle with balsamic reduction or glaze for a sweet tangy finish.

Storage/Reheating

FAQs

How do I peel pearl onions easily?

Partially cook (steam, microwave, or blanch) them for 1–2 minutes, then plunge into ice water and the skins slip off easily.

Can I use frozen pearl onions directly?

Yes — but thaw or partially cook them first to avoid excess moisture and help the coating adhere.

What if some onions aren’t crisping equally?

Make sure they’re in a single layer, shake halfway through, and spray oil lightly and evenly on all sides.

Will the coating fall off during cooking?

Chilling before cooking helps the coating set. Also avoid overhandling and overcrowding in the basket.

What temperature works best?

380 °F is a good starting point for crisping without burning. Adjust slightly based on your air fryer’s performance.

How do I avoid soggy onions?

Ensure onions are dry before coating, don’t overcrowd the basket, and serve right away to preserve crunch.

Can I freeze cooked onions?

Freezing is not recommended — the texture changes and crispness is lost upon thawing.

What dipping sauce pairs well?

Aioli, ranch, spicy mayo, balsamic glaze, or creamy mustard all work beautifully.

Can I bake them in the oven instead?

Yes — bake at 400 °F (200 °C) for 15–20 minutes, flipping halfway, until golden.

Conclusion

Air fried pearl onions offer a delightful combination of crisp exterior and tender, sweet interior in a compact, flavorful bite. With minimal oil and a simple coating, they transform ordinary onions into an impressive appetizer or side. Try variations in spices or accompaniments to suit your taste, and enjoy them fresh and hot for maximum crunch.
