What you’ll need

Ingredients

2 servings

2

small sweet potatoes (about 10 oz. total)

2

Tbsp. neutral oil, such as canola or grapeseed

½

tsp. kosher salt

2

Tbsp. tahini

2

Tbsp. white miso

2

tsp. distilled white vinegar

1

scallion

1

tsp. raw sesame seeds

Preparation

  1. Step 1

    Preheat oven to 450°. Rinse 2 sweet potatoes, rubbing to remove dirt from skins.

    Step 2

    Cut potatoes into quarters lengthwise, then cut each wedge in half crosswise into 2"-long pieces (think a nice size to eat with your hands).

    Step 3

    Toss potatoes, 2 Tbsp. oil, and ½ tsp. salt on a rimmed baking sheet. Roast, tossing every 5 minutes, until a knife easily pierces flesh but exterior is still crispy, 15–20 minutes total (really important since you are cooking them at such a high temperature!).

    Step 4

    Meanwhile, mix 2 Tbsp. tahini, 2 Tbsp. miso, 2 tsp. vinegar, and 1 Tbsp. water with a fork in a small bowl until smooth.

    Step 5

    Trim root end off 1 scallion, then thinly slice from bulb to dark green tip.

    Step 6

    Heat a small dry skillet over medium. Toast 1 tsp. sesame seeds, tossing constantly, until fragrant and golden, about 30 seconds.

    Step 7

    Spread tahini sauce on a platter. Arrange potatoes over. Top with sesame seeds and scallions.

  • Sounds great but I hate vinegar and would also substitute lemon juice. And go lighter on the salt.

  • That is a lot of miso, the stuff is like a salt lick. I like my ratio of 2 Tbsp. of miso with 1/4 c. of tahini. Vinegar is good, but I prefer lemon. Goes great with anything really, I like it with salmon, quinoa and veggies.

  • I make this all the time! So delicious and very easy. Can be a meal of its own or a side to something else. To reduce overall saltiness I do not salt the potatoes when I put them in the oven and manage the sauce to potato ratio (even though the sauce is sooo gooood).

  • I definitely agree with the comments saying it was too salty! I found the sauce did not go well with the sweet potato. I opted for a greek yogurt based sauce and it was 10x better. I used 1/2 cup greek yogurt with 2 tbsp of lemon juice and a pinch of sugar. Game changer!

  • Soooo good... a combination I would've never thought of, but that is so satisfying, and so easy. My only alterations are that I use white wine vinegar instead of distilled, and I go lighter on the salt, especially so if the miso I have on hand is extra salty. Family and friends have loved this dish!

  • I loved this recipe. I saw many reviews that said there was too much salt, but I thought the salt was perfect; it seems it’s up to personal taste. I didn’t have any tahini on hand, so I made my own with a googled recipe. I topped it off with Peruvian chicken sauce (also on Google) and the suggested scallions. Highly recommend!

  • I love the concept for this dish! Unfortunately the sauce was so salty I couldn't stand it! The salty miso flavour was way too overpowering. I consulted a few similar miso-tahini dressing recipes to salvage the ingredients (added maple syrup, more tahini, water) but I still would've preferred to just start new with a different dressing. Still after changing the dressing, the dish was pretty tasty and I would make something like this again....we ate it with aubergine as well as sweet potato

  • The sauce is definitely salty, not really in a bad way though because it comes from the miso. I do think the whole dish needs something to brighten it up, so I added some dollops of yogurt which cut the saltiness. My potatoes looked super charred (like in the gif) but tasted good, not bitter or burnt.

  • another recipe listed with 66 recipes for passover that are not for passover. tahini is made from sesame seeds and are not allowed during passover. You need someone to check your recipes before you post them in a list of recipes for passover.

  • The miso-tahini sauce is delicious! I used 1.5 Tbsp of the miso because it is quite salty on it's own and I didn't want to overdo it. I think this combo is great.

  • So yummy - can't believe I haven't thought of using this dressing with sweet potahtoes before! When I make it again, I would use: - red miso instead of white (I find it to be a little bit more umami). - about half the tahini (I use un-hulled, stone-ground - not to be fancy but because it's healthier + yummier!) - I'd also use lemon juice instead of vinegar (just has a nice 'earthier', less jarring taste than vinegar imho). - Would boil until quite soft, then rub oil and salt onto unpeeled sweet pot's (the salt helps the caramelization) - Best to roast without oven fan in fairly hot oven - the longer the better, even when parboiled, say 20ish mins for that lovely, crunchy outside - mmmmmmm. (I don't turn at all - but keep an eye on 'em). - Oh and I'd also throw a few crushed cumin seeds, in with the sesame seeds when pan-roasting. Yum! -

  • I wonder if people are using cheap instant miso or something. The sauce is on the saltier side, but not overly so, and we were really pleased with how it came out. This would be a great prep method for other root vegetables.

  • Loved this recipe. The sauce was new to me but it was perfect with the sweet potato.

  • Wasn't blown away by the sauce honestly. I didn't find it too salty, since 1/2 a teaspoon is very little salt. Not sure why people are finding that to be a lot. Also, it's definitely 2 tablespoons of oil, that's a reasonable amount to toss the sweet potatoes in for roasting. Didn't like the sauce much, but I'd probably use the same method for roasting sweet potatoes again. Might try it with the Miso Honey sauce from another basically recipe!
