Easy Air Fryer Potatoes and Onions

If you have an air fryer, you know by now how handy it can be. It’s not just great for making “fried foods” healthier. The air fryer can be used to cook so many other recipes, like this Air Fryer Onions and Potatoes recipe.

We love using the air fryer to roast potatoes. The key is making sure that the potatoes are cut evenly and that they are spaced out on the air fryer tray. Then they are cooked evenly and get that perfect texture on the outside. The hot air circulates around each piece leaving them tender and fluffy on the inside and crispy on the outside, just like it does for our favorite air fryer baked potatoes and air fryer sweet potatoes.

With this recipe, we’re also adding onions. And when onions are cooked in the same way, they produce a caramelized sweet but savory addition to the recipe! And now those two ingredients pair perfectly together for the ultimate quick and easy side dish.

Tips for Success

Here are a few things to keep in mind when making this air fryer onions and potatoes recipe.

  • Use different seasonings. Change up the seasonings to whatever you like. You can try dried rosemary or for a spicy kick add our favorite Homemade Cajun Seasoning.
  • The size of the cut matters. Cut the potatoes as close to size as possible for even cooking. We like to cut them into smaller pieces to ensure that they get nice and crispy! As for the onions, we cut them into long slices so they do not fall under the cooking tray.
  • Always preheat the air fryer. Just like you wouldn’t put french fries in cold cooking oil, you don’t want to put these potatoes in a cold air fryer.
  • All air fryers are a bit different. So, it’s best to check after about 12 minutes to make sure that yours are cooking the way you like.
