Miso Sweet Potatoes

4.2

5 Reviews

Inspired by melting potatoes, we gave the same treatment to sweet potatoes. The results? Roasted potatoes that are creamy on the inside but perfectly crisp on the outside. Adding miso to the butter mixture adds great umami flavor and helps the potatoes caramelize while baking. Don't skip lining the baking sheet or the miso-butter might burn on the pan and cause the sweet potatoes to stick.

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
