I’m literally obsessed with these roasted sweet potatoes with miso. In fact, they just might become my new favorite comfort food. They are so easy to make, packed with umami flavors and terribly addictive! It’s like ordering a fancy dish at a restaurant, except you make it yourself – and of course they taste better, cause everything homemade tastes better! Now let’s talk about the recipe.
What are miso roasted sweet potatoes?
These miso sweet potatoes are a unique fusion dish, loaded with Japanese umami flavors. The sweet potato wedges are first coated in a subtle mixture of sesame oil, miso, maple syrup and paprika to bring up the spicy flavors, and then roasted in the oven until crispy.
The other part of the recipe is about the miso sauce itself, prepared with miso, rice vinegar, maple syrup and tahini to make it smooth. Dip the crispy sweet potatoes into the sweet and sour miso sauce, and devour!
Ingredients you need to make sweet potatoes with miso?
- Sweet potatoes. I recommend you choose them medium in size, with an orange flesh. Rub out the dust from skin, and keep the skin on for extra crispiness.
- Sesame oil. You need just a little of sesame oil to coat the sweet potatoes before roasting. The distinct toasted sesame aroma adds a rich, nutty flavor that will make your roasted sweet potatoes extra delicious.
- White / Shiro miso paste. This fermented paste adds a salty umami flavors to many Japanese dishes. You usually find it in the refrigerated section in your grocery store.
- Rice vinegar. If you are not familiar with rice vinegar, know that it is lightly sweet and sour, and particularly adapted in Asian cooking. Do not replace with any other vinegar in this recipe.
- Smoked paprika. It will bring up the spicy flavors of the sweet potatoes and will pair perfectly with the umami miso sauce.
- Maple syrup. It adds a little touch of sweetness to the existing flavors. For a non vegan option, you can replace with honey.
- Ginger (optional). I recommend fresh, grated ginger for more flavors. Occasionally you can go for ground ginger instead.
Other optional (but recommended) ingredients. I always recommend to garnish your miso roasted sweet potatoes with sliced spring onions and toasted white and/or black sesame!
How to serve miso roasted sweet potatoes?
Is this a side? A snack? How should I eat these roasted sweet potatoes and what can I serve with them? Here are just a few ideas for inspiration:
- Enjoy as a snack! You can snack on these roasted sweet potatoes with miso anytime of the day! The sweet and sour miso sauce make it a universal dish for both sweet and/or savory cravings.
- Serve as a side dish. These miso-glazed sweet potatoes make a wonderful vegan side dish to any meal. For instance, I love to make sunny-side up eggs and serve them along with these miso roasted sweet potatoes. Delicious!
- Make it a main dish! I love to make it the center of a buddha bowl recipe, completing these miso roasted sweet potatoes with quinoa, raw vegetables along with other ingredients. Another option consists in serving these roasted sweet potatoes with lentils (think brown Beluga lentils or Puys lentils). Both options make an amazing, nourishing and healthy meal.
To serve with lentils, rinse 1 cup of beluga under cold water, then place in a saucepan and cover with 3 cups of cold water. Let cook on low-medium heat for about 20-25 minutes, or until lentils are cooked through but not mushy. Rinse under cold water in a colander, then transfer to a serving bowl and coat with 1 Tablespoon vegetable oil (neutral in taste, or use sesame oil). Season with salt and pepper, and enjoy topped with roasted sweet potatoes drizzled with the miso sauce. Delicious!
Quick recipe variation: oven-roasted sweet potato halves
Instead of cutting the sweet potatoes into wedges, you can simply half them lengthwise, brush with the sesame-miso mixture, and roast cut-side down at 425°F (220°C) for about 20 minutes. Turn them on the other side and roast 5-10 more minutes, finishing with a couple of minutes under the broil to get a lovely charred texture (monitor the oven closely to prevent from browning). When ready to serve, spoon the miso-ginger sauce on top, garnish with toasted sesame, sliced spring onions, and enjoy!

- 1 teaspoon white / shiro miso paste
- A pinch of sea salt

Notes
* I recommend keeping the skin on the sweet potatoes for extra crispiness.
** To make the sauce extra creamy, you can add 1 to 2 teaspoons vegan/non vegan sour cream. Also, the tahini can be replaced with unsweetened cashew butter if desired.
