My guilty pleasure are homemade sweet potato chips! I could easily go through a bowl full in one sitting all on my own!

It doesn’t help that they’re so. easy. to make. All I need to do is slice sweet potato and bake until crispy!

When I’m not snacking on these, I’m usually going through Air Fryer Masala Sweet Potato Fries!

How to make Baked Sweet Potato Chips

Pre heat oven to gas mark 4-5/160C/350F.

Mix the olive oil, orange zest and half of the thyme in large bowl and set aside to allow the flavours to infuse.

Using a mandolin, vegetable peeler or sharp knife, slice the sweet potatoes into wafer thin slices.
Spread out the sweet potato slices on a paper towel to remove excess moisture.

In the bowl with the orange oil, toss in the sliced potatoes and coat well.

Brush your baking sheets with the orange oil.

Arrange thinly cut slices in a single layer on a baking tray and brush tops with the orange oil.
Sprinkle with the rest of the thyme, sea salt and freshly ground pepper.

Bake for 20 minutes on a middle shelf, flipping at the half way mark. Look out for these signs: the edges of the crisps should curl up and the centre should be golden brown. Keep an eye on them as they can burn easily.

Remove from the oven and allow to rest 2-3 minutes on the baking sheet, then remove carefully and let cool on a wire rack. 

They will go crispier as they cool.

Air Fryer Method

You can get great results by air frying too!

Simply arrange in the air fryer basket in a single layer and brush on the flavoured oil

Air Fry at 160C or 320F for 10-15 minutes. I would keep a close eye on the chips to ensure they do not burn.

Once the air fryer signals that the time is up, open the air fryer basket as the remaining heat continues to cook the food and it may cause it to burn.

Pro Tips

Ensure to slice the potatoes in even thickness – this helps to cook all the chips at the same time

Use a mandolin to quickly and evenly slice. Some mandolins allow you to adjust the thickness too.

To go super crispy, slice as thinly as possible

Keep an eye on the chips as they can easily burn, especially at the edges. If you see this happening, lower the heat.

Note that sweet potato crisps darken as they roast. This doesn’t mean they’re burning, the sugar is simply caramelizing.

Storage

Sweet potato crisps are best enjoyed on the same day at their crispiest.

However, leftovers can be stored in an airtight container for 2 days. Enjoy them at room temperature.
