These potatoes. THESE POTATOES. I can't get enough. They are unreal: sweet, spicy, savoury and filling, and everything I ever want in potatoes. They just might be my new favourite recipe! You should definitely make them tonight. Maybe share them, or don't. No judgement :P

Spicy sambal tahini mayo


  1. Preheat the oven to 350°F (180°C). If desired, keep the skin on the potatoes as we did for extra crispiness and fibre. Cut the sweet potatoes into wedges.
  2. In a large bowl, combine the sesame oil, miso paste, sambal, maple syrup, and ginger. Use a fork to mash and mix to combine. Add the sweet potato wedges and toss to coat.
  3. Transfer the coated sweet potatoes to a parchment-lined baking tray and roast for 35 - 40 minutes, or until fork-tender and golden on the edges*.
  4. To make the tahini mayo, add all the ingredients to a small bowl and mix to combine.
  5. Serve the potato wedges with the tahini mayo. Garnish if desired. Enjoy!


  • * Optional tip: once the potatoes are cooked, turn on the broiler and broil for 1 - 2 minutes, or until the potatoes are crispy and golden.


  • Best enjoyed fresh out of the oven.
  • Store leftovers in an airtight container in the fridge for up to 3 days.

I brought these to a family birthday dinner a few months back and now they’re requested at EVERY family event. The potatoes are delicious and the sauce is complex and creamy and salty and spicy - haha, more or less perfect.

So honoured the recipe was part of the special occasion, Sara, it means so much!

I love this recipe! Just wondering: is there a specific type of miso you would recommend?
For instance, is it better to have white miso (lighter taste) or would you recommend a red miso or koji miso (more umami taste)?
Apologies for the nitty picking, I just wondered what was the intended type (to be the most faithful to the original taste).
Again, love this recipe!

Hey Alica, great question - we used red miso, but I imagine white miso would also taste just fine if that's what you have on hand 😊 I hope this helps for now!

I have made these countless times. They are absolutely scrumptious!

These are easily the best snack I've had in a while! I added salt, which I think really brought out the flavours more, but it would be totally fine without it too. I also added some roasted garlic to the mayo and loved it! My only note is that I cut the recipe down since I only had one medium sweet potato and I think it could've done with more marinade. So, so delicious!

Thanks a bunch for sharing this, Gabrielle! We're so grateful to have you in the PUL community 😃

As a swede, I was naturally suspicious about using maple syrup (not common at all in savoury dishes, only sometimes for sweets, honey is predominantly used)
I must confess that it actually enhanced the earthiness of the sweet potatoes. So did the salty miso paste. Nevertheless, I had to put a little bit of salt for flavour balancing. Baking time and temperature were absolutely perfect 👌🏻 Crispy peel and surface, a soft core that almost melted whilst eating

Woohoo! We're so happy to hear the mayo was a success and enjoyed, Louise. Thank you for sharing :D
