These Air Fryer Parmesan Sweet Potatoes make a perfect side dish for your meal. They are super quick to make and have a great balance of sweet and savory flavor that you’ll love.
I could probably eat these sweet potatoes every day. I love potato wedges and cottage fries, especially made in the air fryer, but we eat those so often that it’s fun to try something new once in a while. They’re amazingly good.

Why You’ll Love It
- You’ll be surprised by how sweet and delicious these sweet potatoes are. They’re very similar to sweet potato fries or sweet potato wedges, but even more like candy in a bowl. This really is our favorite way to eat sweet potatoes.
- In the air fryer, each cube of potato crisps up nicely on the outside, while the inside becomes so soft and sweet. The savory flavor of the butter and Parmesan cheese offsets the sweetness, making them irresistible little morsels.
- You can pair these with just about any main dish, which makes them versatile for any dinner.

Ingredients You’ll Need For This Parmesan Sweet Potato Recipe
- Sweet potatoes – 1 1/2 pounds or 2 large sweet potatoes, peeled and cubed
- Butter – Use salted butter for the added flavor.
- Parmesan cheese – We always like to grate the cheese fresh but use what you have handy. Finely grated cheese works best here.
- Salt and black pepper
- Garlic – A fresh clove, minced. Optional
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.
Expert Tips to Follow
- Finely grated Parmesan works best for this recipe. You can grate your own with a micro planer to get it very finely shredded, or buy it that way. Larger grated cheese doesn’t work as well. It doesn’t coat the potato pieces well, so it falls off or turns a bit greasy.
- The sweet potato cubes don’t have to be in one layer. They’ll cook even when stacked up. Just make sure to give them a shake half way through cooking.
- Try this recipe with regular potatoes as well.
Why Use an Air Fryer
An air fryer is an incredibly easy way to cook just about anything. You place the food in a fryer-style basket and hot air rapidly circulates all around the food, making the food crisp – much like deep-frying, but without the oil. You can cook anything you’d make in the oven.

How to Make Air Fryer Parmesan Sweet Potatoes
Step 1: Prep the sweet potatoes
Start by washing the sweet potatoes well. Peel and dice them into cubes, trying to keep them all the same size. They will cook more evenly that way.
Step 2: Toss with seasoning
In a large bowl add the sweet potato cubes, butter, Parmesan, salt and pepper. Add minced garlic or some garlic salt, if want it.
Toss them in a bowl with the ingredients until they’re well coated.
Step 3: Cook
Pour the sweet potatoes into your air fryer basket. It doesn’t have to be in one layer. They’ll cook even when stacked up.
Cook them in the air fryer at 400° F(204°C) for about 20 minutes, shaking the basket halfway through to cook evenly.
Serve them right when they come out of the air fryer, with a little of the extra Parmesan sprinkled on top.
What to Serve with This Dish
There are so many options for main dishes to serve with this dish. You can make these all in the air fryer or in the oven, if you wish.
How to Store & Reheat: Quick Tips
Storing
Allow any leftover sweet potatoes to cool at room temperature before storing. Store them in an airtight container place them in the fridge for 3-4 days.
You can freeze the sweet potatoes both before or after cooking. For the best outcome, make sure they are in an airtight container and they should be good for 2-3 months.
How to Reheat
These sweet potatoes can be reheated later, but they’ll lose their crispiness.
Air fryer: Put the leftovers into the air fryer basket for about 5 minutes on 400° F(204°C) to warm and crisp them again.
Oven: Place the sweet potatoes on a baking sheet and bake at 400° F(204°C) for 5-10 minutes.
Microwave : Place in a microwave safe bowl and microwave for 2 minutes. This option will result in the least crispy potatoes.

Questions About Air Fryer Sweet Potatoes
Why do my sweet potatoes burn in the air fryer?
Ensuring uniformity in the size of your sweet potato cuts is crucial. If some are larger than others, you’ll encounter uneven cooking times, resulting in larger pieces taking longer to cook and smaller ones potentially burning.
What is the trick to getting things extra crispy with an air fryer?
Using a small mist of cooking oil will help all kinds of things crisp up in the air fryer. If your potatoes don’t look like they are crisping up when you shake the basket half way through cooking, spray them with some cooking oil.
Do I have to peel the sweet potatoes?
No, you don’t have to peel them because the skins are edible. We choose to peel them in this recipe. The texture and taste will be different if you leave them on. It really comes down to your preference.
Do I need to boil the sweet potatoes before roasting them?
We don’t boil the sweet potatoes in this recipe. While you certainly can, it isn’t necessary because the sweet potatoes are cut into such small chunks that they cook well without it. In the end it is just one more step and more dirty dishes for nothing.
Can I bake these in the oven instead?
Yes, and they will come out great! Place them on a baking sheet and bake at 400°F(204°C) for 12-15 minutes. Stir them half way through cooking.
