These Thai-inspired sweet potato skins are bursting with amazing flavours – peanuts, chillies, lemongrass, spring onions and coconut. I love them as an alternative to regular jacket potatoes, and they even happen to be vegan!

A vegan recipe? on Nicky’s blog?

I know!

Most of my savoury recipes are usually meat-centred.  I am trying to incorporate more vegetarian food into our diet and the blog (check out this yummy garlic bread spaghetti or this nutty noodle salad), but I thought it was impossible to create something we’d all enjoy that didn’t contain lots of cream or cheese.  Until I made these!

Potato skins, stuffed with velvety sweet potato and a mixture of crunchy, spicy zingyness.

Serve them with a nice leafy salad for lunch, or if you still need some meat in your life, try them with my satay chicken skewers.  The satay sauce contains many of the same ingredients as the filling for these skins, so you can save yourself a little effort.

🔪 How to make these spicy potato skins

Full recipe with detailed steps in the recipe card at the end of this post.

  • Prick the potatoes and bake in the oven until tender, then cool for 10 mins.
  • In a bowl, mix peanut butter, lime juice, soy sauce, chilli, coconut milk, brown sugar, ground coriander, spring onions and lemongrass paste.
  • Slice the potatoes in half and scoop out the flesh. Place the skins back in the oven for a few minutes to crisp up. Add the sweet potato flesh to the bowl with the peanut butter mixture. Stir to combine.
  • Take the skins out of the oven and fill with the sweet potato mixture.
  • Place back in the oven for 10 minutes, then serve!

  1. You say a 1/4 tin of coconut milk. Usually (in supermarkets) it’s either 200ml or 400ml. Which one are you referring to?

  2. 5 stars
    Just discovered I love sweet potatoes, and I love Thai flavours, so these are definitely a winner for me.

  3. You make me speechless with the deliciousness you bring to my party every time! This look fantastically delicious! I can’t wait to see what you share in your next blog.

    1. Hi Michelle, I’m in the UK (not sure where you’re located) and I usually find it on the Asian aisle – if they have chilli paste or garlic paste at your supermarket it’s usually with those (in a jar). Alternatively you might find tubes of it located with the fresh herbs.
      It’s quite a unique lemony-floral taste, so hard to substitute. If I didn’t have any in though I’d probably add a little lemon zest and ginger.

  4. This! Sweet potatoes are my fave, so yum to this! I hope you submit this to, because it looks amazing! 🙂

  5. A thai flavoured sweet potato skin sounds fabulous! And these look great too. I love that they are healthy as well – I can so see myself making these.

  6. Nicky! These are gorgeous! I cannot wait to try them. I love Thai flavours, and I think I’d bleed sweet potato is someone cut me open – so these are ultimate Amy food 🙂
    And I remember something my Mum said when I asked her about growing up (and her reaction to it) she said ‘you’ve just got to make the most of the season’ from princesses to eye rolls and Harry Potter missions and everything beyond 🙂

  7. YUM! I love stuffing sweet pots with goodness and I love the variety of Thai flavors you put in these 🙂
