You only need a few simple ingredients to make these air fryer potatoes and onions. This easy vegetable side dish comes together in a few steps, and the air fryer delivers potatoes that are crisp on the outside and tender inside while the onions caramelize beautifully.
Quick to prepare and full of flavor, this air fryer potatoes and onions recipe is perfect for busy weeknights or as an easy addition to a weekend meal. Minimal hands-on time makes it a convenient, satisfying side.
Why You’ll Love This Air Fryer Recipe
- Hands-off cooking: once the potatoes and onions are in the air fryer, you only need to shake the basket once or twice.
- Simple and reliable: chop, toss with oil and seasonings, and cook for crispy, golden potatoes and caramelized onions.
- Great texture and flavor: the air fryer crisps the potato edges while keeping the centers fluffy and brings out the onions’ natural sweetness.
Ingredients You’ll Need
- Potatoes — Russet potatoes work well for a crispy exterior and fluffy interior; Yukon Golds are a good alternative. I leave the skins on for extra texture, but you can peel if preferred. Scrub and dry thoroughly.
- Onion — Red onion is used here for color and mild sweetness, but yellow or white onions are fine substitutes.
- Oil — Olive oil is used for flavor, but any neutral oil with a high smoke point will work.
- Seasoning — Kosher salt, ground pepper, garlic powder, and onion powder. Adjust or switch in other seasonings to taste.
How To Make This Air Fryer Potatoes and Onions Recipe
- Place the cut potatoes, quartered onions, olive oil, kosher salt, ground pepper, garlic powder, and onion powder in a large bowl.
- Toss everything until the potatoes and onions are evenly coated with oil and seasoning.
- Arrange the seasoned vegetables in the air fryer basket in a single layer if possible for the best crisping.
- Air fry at 390°F for 15 minutes, shaking the basket halfway through to ensure even browning.
- If all pieces don’t fit in a single batch, cook remaining potatoes and onions the same way to maintain texture and crispness.
Recipe Variations
- Add heat with a pinch of cayenne pepper or red pepper flakes.
- Swap or add seasonings such as smoked paprika, Italian seasoning, chili powder, Cajun seasoning, or Old Bay for different flavor profiles.
Tips and Notes
- Cut the onion into large wedges rather than small pieces to prevent burning and to keep them tender and sweet.
- Check the onions at the halfway point; if they’re browning too quickly, remove them early.
- Cook in batches if your air fryer is crowded. Overfilling increases cook time and reduces crispness.
- Garnish with fresh herbs like thyme, parsley, cilantro, or chives for brightness before serving.
- Cut the potatoes into uniform pieces so they cook evenly.
How do I store leftovers?
Allow leftovers to cool to room temperature, then store in an airtight container in the refrigerator for up to 5 days. Reheat in the air fryer until warmed through to restore crispness.
