These miso butter sweet potatoes are perfectly crispy on the outside and soft in the center. I loaded mine with a healthy dollop of the miso butter, scallions, and toasted sesame seeds. It was perfect. You can also add a few turns of cracked black pepper for some extra flavor. To make this recipe vegan, simply use a vegan butter of your choice.

For this recipe, I used white sweet miso. As background, white miso is lighter, sweeter, and milder than its red miso counterpart. It also does not taste as salty as the red miso paste. Both are great in so many ways, but yet very different. So, be sure you are using the right one when you make this recipe. Otherwise, it may not turn out as you expect.
