I've been making roasted sweet potato chunks in the oven for ages, but now I have an air fryer I find that the best way to make these is in the air fryer. They cook in less time and I use less oil making them healthier too!
These really are so easy to make and are such a versatile side dish. The whole family will love these. I also add them to my Falafel Bowls or my Kale and Quinoa Salad, their crispy exterior and tender middle make them great for adding extra texture to your salads.
What You'll Need
- Sweet Potatoes - You'll need two medium whole sweet potatoes for this recipe. Look for sweet potatoes that feel heavy for their size and have no bruises, soft spots, or signs of sprouting.
- Seasoning - I use dried oregano, smoked paprika and garlic powder for these. You'll also need salt and black pepper.
- Oil - I add olive oil to this recipe. You can use other oils if you like I would just avoid using extra virgin oil as that will be too strong in flavour.
How To Make Air Fryer Sweet Potato Cubes
1. Peel the sweet potatoes then using a sharp knife cut them into cubes. I like one-inch cubes but you can make them smaller if you need to.
2. Add the oil, oregano, spices and salt and pepper to a large bowl and mix well. Next, add the sweet potato cubes and toss well so that they are covered in the oil and herb mixture.
3. Add half the sweet potato cubed into the air fryer basket, making sure they are all in a single layer. Cook for 10 - 12 minutes at 200 degrees C / 400 degrees F. Halfway through cooking give the air fryer basket a good shake. Check that the potatoes are cooked by piercing them with a sharp knife, the knife should go in easily. Cover the sweet potatoes to keep them warm. Repeat with the remaining sweet potatoes.
Serving Suggestions
We love these added to salads but they are also a great side dish to my Halloumi Burgers or my Portobello Mushroom Sandwiches. Another great way to use these is to add them to tacos or curries. We also like these as a healthy snack with some hummus.
Variations
- Switch up the seasoning - make them spicy by adding chili powder or cayenne pepper instead of smoked paprika. Or add onion powder to add a sweet-savoury flavour. Cajun spices and Italian seasoning also work really well.
- Make them sweet - swap out the savoury herbs and add a little cinnamon and maple syrup for a sweeter option.
Top Tips
- The best way to cut the sweet potatoes into cubes is to top and tail each sweet potato. Slice the potato into thick slices lengthways. Lay each slice flat on a cutting board then cut each slice into three slices lengthways, then cut each slice into 4 pieces widthways. I always place a tea towel under the cutting board to prevent the board from slipping.
- Make sure the sweet potatoes are in an even layer in the air fryer basket. This avoids the cubes from touching each other and sticking together.
- For best results don't overload the air fryer, you will need to cook these in two batches. If you put too many in they will end up soggy.
- Try and cut the sweet potatoes into uniformly sized pieces, this will ensure they all cook at the same time. Allow extra cooking time for larger cubes.
FAQs
These really are best served straight away. However, you can store leftovers in an airtight container in the fridge and use them within 3 days.
Yes, you can. I reheat these using the reheat function on my air fryer.
No, sweet potatoes do not have as much starch as white potatoes so there is no need to soak these before cooking.
