Ingredients
- 4sweet potatoes (about 6 ounces each), scrubbed
- 1clove garlic, chopped
- 1(1-inch) knob of fresh ginger, peeled and grated
- A few pinches of sugar or 2 teaspoons mirin
- 1heaping tablespoon white miso
- 1tablespoon unseasoned rice wine vinegar
- 1tablespoon light sesame oil or other neutral oil, plus more for the pan
- 1tablespoon toasted sesame oil
- 2teaspoons toasted black sesame seeds, for garnish
Preparation
- Step 1
Add about an inch of water to a stovetop steamer or a pot fitted with a steaming basket. Add sweet potatoes and steam until tender, 30 to 40 minutes, depending on their size.
- Step 2
While sweet potatoes are cooking, make the sauce: pound garlic and ginger in a mortar until very smooth and then stir in the sugar, miso, vinegar, sesame oils and 1 tablespoon water.
- Step 3
Halve steamed sweet potatoes lengthwise and score the cut sides in a crisscross pattern with a small knife. Heat a large skillet or grill pan over medium-high heat. When hot, add a swirl of light sesame oil (about 1 tablespoon), then add sweet potatoes in a single layer, cut side down, and cook for 3 minutes, or until their natural sugars caramelize and turn an appetizing golden brown. (Depending on the shape of your potatoes, you may have to work in batches.)
- Step 4
Arrange sweet potatoes on plates or a platter and spoon sauce over them. Garnish with sesame seeds and serve alone or with any accompaniment you like.

This sauce will taste great on ANYTHING! I roasted large slabs of butternut squash in the oven set ay 465 for about 1/2 hour, drizzled with a little oil. It browned the squash beautifully! I prefer this to SP, as they are too sweet for my taste.
In the bowl I added:
brown rice
pickled slivered beets
fresh baby greens
steamed purple kale
shredded carrot
and of course the black sesames + the MAGIC sauce.
A beautiful, colorful dish that could have been served in a restaurant.
I have never used miso. where in the supermarket would I find it?
My local grocery store has miso in the refrigerated section where you'll find tofu, cheeses, humus and specialty prepared foods. If you have an Asian grocery store in your area, you'll find a better variety there. Take note this recipe calls for white miso...other kinds, red, for ex. have different flavor. You can order artisan miso from South River Miso here in Massachusetts. (No, not relatives of mine...I just love their misos!) www.southrivermiso.com has recipes too.
Sauce was great as a meal for one served over a steamed sweet potato and spinach plus a salmon burger from my freezer. Added gauchujaru, scallions, and parsley to punch up the sauce.
super yummy! I sliced them in half and roasted bc i didn't have a steamer. subbed lime juice for rice wine vinegar and the sauce was still not bad but next time i'd just buy the vinegar
Made it exactly as written and served with white rice, radish, green onions, and frozen peas and carrots (cooked in garlic and soy—I thought I had spinach but had to go the toddler route!). Absolutely delicious and a great way to use some of that miso you have in the depths of the fridge.
