15-Minute Garlicky Air Fryer Onion Wedges

These onion wedges cook to tender, caramelized edges with almost no effort. The air fryer does the work while you get the rest of dinner together.

They work as a side for anything off the grill, or piled into a burger bun with a swipe of mustard. No standing over a hot pan, no deep fryer, just a quick toss and the machine takes it from there.

What Makes These Onion Wedges So Good

I keep this recipe in my back pocket because it turns one humble onion into something with real texture and char. The air fryer’s dry heat pulls out the natural sweetness while the edges go crisp enough to feel intentional, not burnt.

The garlic powder and a little salt give it backbone without masking what an onion already does well. I usually toss the herbs in right at the end so they stay bright.

Ingredients

• 2 large sweet or yellow onions: sweet varieties mellow more, yellow hold their structure
• 2 tbsp olive oil: enough to coat without making them soggy
• 1 tsp garlic powder: not garlic salt, you control the salt separately
• ½ tsp fine sea salt: add more to taste after cooking if needed
• ¼ tsp black pepper: fresh ground gives a sharper pop
• ½ tsp smoked paprika (optional): a little warmth and color

Variations / Substitutions

• Red onion wedges: slightly sharper, cook the same way but watch for a minute less
• Parmesan finish: toss the hot wedges with a tablespoon of grated parm
• No oil: a light avocado oil spray works, but the browning won’t be as even
• Herb swap: fresh dill or chives instead of parsley at the end

Air Fryer Scallops are the main dish we love pairing with this recipe.

How to Make Air Fryer Onion Wedges

Step 1: Cut the Onions

Peel the onions and trim both ends. Set each one on a flat end and cut it in half through the root, then cut each half into 4 wedges. Keep a bit of the root core attached so the layers don’t fall apart during cooking.

Step 2: Season the Wedges

Put the wedges in a large bowl. Drizzle the 2 tbsp olive oil over them, then sprinkle on the garlic powder, salt, pepper, and paprika if using. Toss with your hands until every wedge is slick and evenly coated.

Step 3: Air Fry at High Heat

Arrange the wedges in the air fryer basket in a single layer with a little space around each one. If your basket is small, work in two batches. Set the air fryer to 400°F and cook for 12 minutes, shaking the basket once halfway through. The edges should be browned and the centers tender.

Step 4: Toss with Fresh Herbs and Serve

Slide the hot wedges onto a plate and scatter chopped parsley or chives over the top. A final pinch of flaky salt right before they hit the table makes a difference.

Before You Start

• Cut the wedges about the same thickness so they finish together. Thinner pieces burn, thicker ones stay raw in the center.
• Don’t crowd the basket. Stacked wedges steam instead of browning. Give them room.
• The smoke point of olive oil works here at 400°F, but avocado oil is a good substitute if you prefer it.

Cook times by air fryer model:

Storing Leftovers

• Refrigerate: cool wedges completely, then store in a sealed container for up to 3 days. They will lose the crisp edges but still taste good.
• Reheating: a quick 3 to 4 minutes back in the air fryer at 375°F brings some texture back. A microwave makes them soft.

What to Serve With Air Fryer Onion Wedges

Pile them next to a grilled steak or a burger, where the char and sweetness both work. For a vegetarian plate, spoon some lemony yogurt under them and add a handful of fresh arugula. They also hold their own next to roasted sausages and a smear of whole-grain mustard.

Frequently Asked Questions

Can I use a red onion instead?

Yes. Red onions have a sharper flavor and cook a minute or two faster, so check them at the 10-minute mark.

My onions didn’t get crispy. What happened?

Too much oil or a crowded basket. A light coat is enough, and the wedges need a little space for air to circulate. Also, shake the basket midway.

Can I do this with sliced rings instead of wedges?

Yes, but the rings need to be thick cut, about ½ inch, and they cook faster. Keep an eye on them after 8 minutes.

Do I need to preheat the air fryer?

Many models have a preheat setting. If yours doesn’t, just add 2 minutes to the cook time while the basket heats up.

Notes

These are best right out of the air fryer when the edges are still crisp. If the wedges vary in size, pull the smaller ones a minute early to avoid over-browning.
