Ingredients
- Potatoes – use whatever potatoes you have on hand! I recommend using yellow (gold) potatoes, red skinned potatoes or baby potatoes for this recipe. These potatoes have thin skin (no need to peel them) and get crispy and fluffy when roasted.
- Onion – use whatever kind of onion you have on hand; red, white or yellow onions would all work in this recipe.
- Olive oil (or avocado oil) – oil helps to ensure that the spices stick to the potatoes and onions and also helps ensure that they get nice and caramelized when roasting in the air fryer.
- Spices: Salt, garlic powder, paprika and dried thyme – these spices are my go-to favorite spice blend for potatoes. They give the potatoes flavor while still making them super versatile so you can use them as a side for pretty much anything. You can change up the flavor by changing up the spices (see below for some ideas).
Top tips
- No need to peel the potatoes before roasting, just make sure they are clean before chopping into cubes.
- Use whatever spices you love. This spice blend helps to create roasted potatoes and onions that will pair well with just about anything.
- If you need to double the recipe, make it in batches. Overcrowding the air fryer basket will make it almost impossible for the potatoes to cook evenly.
- Cut the potatoes into even size pieces to ensure they cook at the same time. Having really large cubes and smaller cubes can cause some of the potatoes to be overcooked while some are still raw on the inside.
- Be sure to shake the basket often after the first 10 minutes of cooking to ensure all the potatoes and onions get nice and caramelized in the air fryer. The larger the air fryer basket, the less you have to shake them.
- Coat the potatoes well in oil before cooking. I recommend doing this in a separate bowl so that you can be sure that everything is well coated. This helps the potatoes really crisp up on the outside as they are cooking.
Other spices
- Ranch – omit the thyme and paprika and add 1 tablespoon dried chives, 1 teaspoon dried parsley and ½ teaspoon dried dill.
- Smoky – add ½ teaspoon smoked paprika or cumin (or both)
- Spicy – add ¼ – ½ teaspoon of red pepper flakes or cayenne pepper
- Taco – omit the dried thyme and add 2 teaspoons chili powder and ½ teaspoon cumin
- Cajun – add 1 tablespoon cajun seasoning
- Curry – omit the dried thyme and add ½ tablespoon curry powder and ½ teaspoon cumin
- Italian – omit the dried thyme and add 1 tablespoon italian seasoning
- Greek – omit the paprika and thyme and add 1 tablespoon italian seasoning, ½ teaspoon oregano and squeeze with the juice of half a lemon after cooking.
How to serve
- For breakfast or brunch alongside of eggs, egg stuffed peppers or smoked salmon frittata
- For lunch in a salad or alongside a sandwich or burger
- As a snack with your favorite dipping sauce and some fresh veggies. Some of my favorite dips for roasted potatoes are chipotle mayo, ketchup, ranch and chimichurri.
- For dinner as a side dish to chicken, beef. meatloaf or salmon or as part of a grain bowl
- Leftovers can be added to salads, in frittatas or egg bakes or in casseroles.
Common questions
What are the best potatoes to use?
The beauty of making air fryer potatoes and onions is that it’s so versatile. It will work with just about all potatoes and onions (and all combinations of them). Here are a few things that might help you when choosing a potato for this recipe:
- Russet potatoes (sometimes called Idaho potatoes) are what you typically use to make mashed potatoes. They are high in starch and sugar and get very golden brown when cooked in the air fryer. Typically these potatoes get even crispier if soaked in cold water for a few minutes before roasting (be sure to dry them off before adding the oil and spices).
- Yukon gold potatoes (or other yellow skinned potatoes) are a great choice for roasting in the air fryer because they are high in sugar but lower in starch. This means that they still get very crispy on the outside but aren’t as starchy and usually create that fluffy inside and crispy outside.
- Red skinned potatoes – red skinned potatoes are more waxy than starchy and hold their shape very well when boiled (these are the best for things like potato salad for example). However they do still have some natural sugars and will get crispy when cooked in the air fryer.
- Baby potatoes – baby potatoes are a mixture of yellow, red and usually purple potatoes. These are very easy to work with since they are already so small (less chopping is needed) and they get super crispy when roasted in the air fryer.
Do you need to peel potatoes before baking in the air fryer?
No, you don’t need to peel potatoes before roasting them, especially thin skinned potatoes like gold potatoes, red potatoes or baby potatoes. If you are using a thicker skin potato (like a russet) you may decide to peel the potatoes first, but that will be a personal preference as it’s not necessary.
Do you need to soak potatoes before roasting in the air fryer?
- I did not notice a difference between soaking the potatoes or not soaking the potatoes, especially when using yellow or red potatoes. That is why for this recipe, I recommend that you use yukon gold potatoes (or gold potatoes), red potatoes for the best result.
- Often it’s recommended that you soak potatoes before roasting to help pull out excess starch so the potatoes will get crispy and fluffy but this is not necessary with the air fryer, especially when using the potatoes listed above.
- If you are going to use russet potatoes (which tend to be more starchy), you may want to soak the potatoes for 5-10 minutes in cold water before cooking. Russet potatoes are very starchy and can also start to oxidize quickly once exposed to air so soaking can be helpful.
How to use leftover air fry potatoes and onions
Air fryer potatoes and onions reheat well on the stove or in the air fryer. If you want to use them in a different dish, you can easily use the leftovers in:
- In salads – crisp up the potatoes and onions first then add them to the salad. They will act like croutons in the salad, giving lots of flavor and helping to make the salad super filling.
- In frittatas or egg bakes – no need to heat the potatoes and onions up first, just add the leftovers to the egg mixture before baking and you have a whole different meal!
- In casseroles – just like the frittatas, there is no need to heat the potatoes and onions up before adding them to the casserole ingredients.
- In burritos, tacos or burrito bowls – crisp up the potatoes and onions before adding them to your burritos, tacos or burrito bowls for a nice contrast in texture!
Storing leftovers
- Fridge: Store leftover roasted potatoes and onions in an airtight container in the fridge for up to 5 days. Note: the potatoes lose their crispy exterior quickly after cooking and especially when stored in the fridge, but you can re-crisp them up on the stove or in the air fryer when reheating.
- Reheat in the air fryer at 375F for 5-7 minutes
- Reheat on the stove in a preheated skillet over medium heat for 5-8 minutes or so or until heated through (be sure to drizzle with some additional olive oil to get them super crispy).
- Reheat in the microwave for 1-2 minutes. This will not create a crisply exterior for the potatoes but will heat them through.
- Freezer: You can freeze leftovers, however I would not recommend it because the potatoes will get a slightly different texture when defrosted. If you have to freeze them (up to 3 months in a freezer safe bag or container), use the leftovers in casseroles or frittatas so that you don’t notice the texture as much.
Substitutions
- Potatoes – use whatever potatoes you have on hand for this recipe. You can also use sweet potatoes, butternut squash or even rutabaga in place of the potatoes. Each of these will require slightly different cooking time and temperatures though so check out the posts for detailed instructions.
- Onions – use whatever onions you have on hand (you can even use shallots). If you only have green onion, wait to add those to the dish after cooking. You can omit the onion if needed.
- Olive oil or avocado oil – use whatever oil you prefer. You could also use melted coconut oil, melted butter or ghee.
- Spices – the only spice that I would consider to be mandatory would be the salt, because salt makes everything taste better. If you are sodium free, use your favorite sodium free seasoning blend. For more ideas on how to spice the potatoes, check out the list above.
