Paleo Korean Caramelized Sweet Potatoes (Goguma Mattang)

Paleo Korean Caramelized Sweet Potatoes Goguma Mattang

I remember eating these caramelized sweet potatoes when I was young for every holiday in Korea with my family. I came to the US when I was 6, but I can still recall gathering with my relatives and eating a feast of delicious Korean foods. I especially loved Lunar New Year, because this was when all the kids would bow to the elders to wish them a bountiful New Year, and in return, they would hand the kids money. It was the best part!

Lunar New Year is just around the corner (Jan 28th) and while I don’t celebrate it like I did in Korea, when Christine from Vermilion Roots asked if I would like to join in on a virtual Lunar New Year party with other awesome food bloggers, I had to say yes!

The recipe I’m contributing is called Goguma Mattang in Korean, and it’s basically deep fried sweet potato wedges that are coated in sweet caramel sauce. They are sticky on the outside and crispy on the inside, and they are pretty much the most addicting dessert ever.

I don’t like to deep fry anything at home, since I like to use stable, heat-resistant oils like coconut oil or duck fat for frying, and it can get super expensive with those healthy oils. So I baked the sweet potatoes in high heat then broiled them to get them extra crispy, and it worked so well!

Even if you don’t celebrate Lunar New Year, I hope you end up making these, because they are absolutely delicious! The honey caramel sauce enhances the sweetness of the potatoes, and this mattang makes me miss my family and Korea so much.

    I have not come across any Japanese sweet potato in Perth :(.
    Your bowl of sweet goodness makes me want to try as soon as I can find Japanese sweet potato or a good substitute.

      I think you can use any kind of sweet potatoes and it’ll still work. Won’t taste like the traditional kind but it’ll still be delicious!

      I thought about getting a deep fryer but honestly, this is just as delicious without frying. Thank you for your kind words!
