Ingredients You Need

ingredients for air fryer potatoes and onions
  • Potatoes: I use russet potatoes for this recipe most often because they crisp up on the outside while staying moist on the inside. Red or yellow potatoes work well too.
  • Onion: Onion has a unique sweet and savory flavor. You can use either red or white onion for this recipe. Cut the onion in chunks as well.
  • Olive oil: Olive oil is rich in healthy fats. You can use any other vegetable oil as well.
  • Garlic powder: Garlic salt adds a great garlic flavor while seasoning the veggies with salt.
  • Onion powder: For a more savory flavor, use onion powder. If you are looking for more depth, add garlic powder as well.
  • Rosemary: Herbs like rosemary (or thyme) don’t just add aroma but also a distinct flavor to the dish. You can choose either fresh or dried herbs.
  • Salt & pepper: No dish is complete without adding salt and black pepper at the end, to taste.

Equipment Information

  • Air fryer: I use this 4-quart basket-style air fryer. It’s large enough to fit a meal for 4-6. But some things need more space in the air fryer basket, so they cook evenly.
  • Kitchen tongs: It’s very easy to remove food from your air fryer with kitchen tongs. I use these kitchen tongs that are silicon coated so they don’t scratch the interior.

How To Store Leftovers

To maintain freshness and flavor, store any leftover potatoes and onions in an airtight container with a tight-fitting lid to keep the aroma from permeating other things in your refrigerator. If you have a large batch leftover, consider separating them into individual portions before storing them.

You can reheat the potatoes and onions in the air fryer basket, just as you did the first time. It will take about 5 minutes on 400° F.

Questions About the Recipe

Can I add peppers to the mix?

Yes of course! This recipe can be made with any additional vegetables you like. I’ve added green or red bell peppers to the mix and it’s fantastic.

Does it matter what potatoes I use?

Nope. Just like with the onion, you can use whatever potatoes you want. I think that russets are the best type because they have a balanced starch level that helps to crisp them without losing their softness inside, but I’ve made it with all different types of potatoes.

Do potatoes and onions cook at the same time?

You can cook both potatoes and onions at the same time in the air fryer, but it takes longer for the potatoes to cook than the onions, so we recommend putting the potatoes in first for 8 minutes before adding the onions.
