This is another one of those dishes that is so simple, it feels silly to call it a recipe. But simple or not, it’s delicious, so it’s worth sharing. When we were in Old Town last month, I ate something similar at Teaism, and immediately announced that I was going to remake it when I got home.
I actually remade it for Cullen’s birthday party a few weeks ago, but I’m just now finally measuring, writing down ingredients, and photographing so I can share with you guys. It was the hit of our party – with both adults and the babies – and a few different friends have been hounding me for the details. So here they are, in all their simplicity.
Roasted Sweet Potatoes with Miso Sauce

Prep Time: 10 minutes
Cook Time: 30-40 minutes
Ingredients (4-6 servings)
-
4-6 medium sweet potatoes
-
1-2 tablespoons olive oil
-
sea salt
-
3 tablespoons white or yellow miso paste (I used chickpea miso)
-
3 tablespoons tahini
-
1 tablespoon lemon juice
-
3/4 cup water
Instructions
Preheat the oven to 375 degrees. I used the serving suggestion of 4-6 sweet potatoes, but really, you can roast however many you like. The sauce keeps well in the fridge for about 7 days, so you don’t have to use it all at one.
Dice the potatoes into even, bite sized pieces. When roasting, always try to get the pieces as similar in size as possible, in order to get even cooking. Place diced sweet potatoes in a single layer on a sheet pan, and drizzle generously with olive oil and salt.
Roast for 30-40 minutes until your potatoes are soft and have developed a good amount of color. Stir once halfway through the cook time.
While the potatoes roast, make your sauce. Add all sauce ingredients to a sauce pan and turn heat to medium-low.
Slowly whisk over low heat – the tahini and miso will be thick at first, but should break down into a smooth sauce. Keep whisking to get rid of all lumps and bumps.
If the sauce is too thick, you can thin out with additional water if needed. Since miso has a naturally salty flavor, you shouldn’t need any additional salt. Pour the sauce into a container that can be sealed in the refrigerator (in case of leftovers!).
This recipe makes about 1.5 cups of sauce, and will keep for a week when refrigerated.
Once the sweet potatoes are ready, toss with sauce and dig in! Easy at that!
For our batch, I roasted four large sweet potatoes, and the final product never even made it to the dinner table. Cullen ended up eating about half of it for his dinner, and Casey and I ate the rest straight out of the bowl.
After gobbling up his sweet potatoes, Cullen started tossing all of his avocado and tofu off of the high chair (his new favorite thing). If I offered him a bite of anything else, he pulled it out of his mouth and or spit it back out. Then I dipped some tofu in the miso sauce, and he immediately chowed down. He finished the rest of his dinner drenched in sauce. So what I’m saying is…the sauce is magical.
This is a great side dish with dinner served immediately, but it’s also delicious the next day. We had some leftovers after Cullen’s party, and I ate the rest of the sweet potatoes the day after – still just as good chilled!
The leftover sauce goes a long way – I’ve been pouring it over bowls of quinoa or rice for my lunches, and drizzling it on veggies at night. Miso and tahini are two of my favorite flavors, so I could eat this sauce on just about anything. But sweet potatoes are definitely a good start.
Enjoy!
PS – For my Babble-reading friends, now that Cullen is one, I have graduated from Baby’s First Year, and am now blogging over at Toddler Times! I hope you’ll continue to follow our journey over there. Thanks!

I like chickpea the best – it’s pretty mild.

I have been waiting for you to post this recipe ever since you posted pictures from Cullen’s birthday party – it looks sooo delicious!
[Reply]
Those sweet potatoes look awesome! I’ve never cooked with miso before but this recipe might convince me too, it looks so easy and delicious!
[Reply]
I’ve been waiting for this one! Can’t wait to try it!

Made this last night and it was delicious! I also roasted beets (not as good with the sauce) and made the cauliflower dish you served at Cullen’s party, and the cauliflower with the miso sauce turned out to be our favorite! I also put the miso sauce on some grilled chicken breast strips (for any non-vegetarians out there) and it was really good with that too. Just about to eat a mixture of the cauliflowers, sweet potatoes, and chicken with the miso sauce for leftovers! :)
[Reply]
Oh yum! Miso anything is worth making. :)

Agreed!

This is so simple!! I’ll have to give this a try.
On a side note: I’m always searching for natural beauty and shower products that aren’t tested on animals and I was wondering if you’d consider doing a post on what it is you use and love.

I did a post on this when I was doing the Being Pregnant blog on Babble. I will see if I can dig up the link!

Simple or not this is so delicious. When you first talked about it without the recipe I had to have it and just mashed a sweet potato with miso and lemon and I loved it! I now have to try it with tahini it looks amazing.
[Reply]
One thing I’ve never cooked with and possibly never tasted is miso. I’m always overwhelmed by all of the choices. I think it’s time to suck it up and give it a go.

Ashley HOW is this possible?? I guarantee you will love it, and I know you will think of far more creative ways to use it than me.
[Reply]
I am so excited! I just bought my first jar ever of miso this week because I knew you could provide me with an awesome way to use it. I am looking forward to making this!
[Reply]
This sounds so delicious – I can’t wait to try it. Now I just need to buy some miso paste.. YUM!
[Reply]
That looks so unique and delicious! Looking forward to trying it!
[Reply]
I can’t wait to try these, this recipe looks awesome! I have never made anything with miso before so this will be a first.

Awesome post…I can’t wait to whip this side dish up tonight!
As a sidenote, the link for “Toddler Times” doesn’t seem to be working for me…it keeps linking me to other non-affiliated sites. Just wanted to let you know!

Um, I don’t know what miso is.. but this looks good, it’s going on the veggie pinterest board :)
[Reply]
Yum! I love sweet potatoes and can’t wait to try this. I haven’t tried miso paste before, but this is a great excuse to start experimenting!
[Reply]
I COULD believe this sauce is magic. My one year old (TODAY!) loves hummus and so I will need to add miso to the sauce I make. Maybe even tonight! I was going to roast some sweet potatoes too. Congrats on having a toddler. Tear…

Congrats to you on a year, mama! Happy Birthday to your little one!

oh YUM! This is actually quite close to a dish my husband lived off for days after having his wisdom teeth taken out: basically the same sauce (plus grated garlic and ginger), poured over sweet potatoes that had been peeled, steamed, and mashed. He couldn’t really chew, and this was a nice change from smoothies and ice cream. I’ll have to try with the potatoes roasted this time!
[Reply]
That looks delicious Emily! So funny about Cullen, he’s a boy with a great palate! I’ll definitely be making that sauce tonight, though i’ll have to put it on butternut or acorn squash tonight as I’m out of sweet pots today. Too lazy to go to the store today.
The sauce reminds me of a dip I learned when I was macrobiotic years ago: any sweet squash or sweet potatoes cooked, tahini and miso to taste, mix well and use as a dip with carrots and celery or spread on toast. It like your sauce doesn’t last long!
Loved Cullen’s Halloween costume, so simple and creative, perfect for the budding runner!
[Reply]
I am so dedicated to your other miso/tahini sauce (which totally goes on everything)…very excited to make this!
And sweet potatoes…I can never get enough!
[Reply]
Looks delicious! Side note, where did you get your top? Very cute!

Mmmmmmmmmmm is ALL i have to say!

Made the sauce today and ate it for dinner over garlic kale and jasmine brown rice, very good! I was starving after a long run today. Next, I’ll try it with sweet potatoes, I often find sweet potates too sweet, so I think this sauce will make them more savory and be perfect. I love South River Miso and usually buy the sweet white miso because its lowest in salt, their tamari is also great.
[Reply]
OOH! CHICKPEA miso! How interesting! NO soy <3 – I will definitely try this :)

The Washingtonian posted a version of this recipe a few years ago:

I like your idea of adding some lemon juice to cut the richness of the Tahini though!

Looks delicious! I’m sort of recently obsessed with miso so will definitely give this a try. Love the simplicity of it too!
[Reply]
My variation of it tonight was adding some fresh garlic and some liquid stevia, I also tripled the recipe because I knew I’d want more tomorrow! Delicious!

There’s nothing you’ve cooked and posted that I don’t like! Now if I could only make done GF and egg-free! I know you’ve written about that, just wishful thinking. ;-) Enjoying every post of Cullen!
[Reply]
Hi Emily! Thanks for this recipe. You’re right – simple and delicious. I loved that I already had all the ingredients and I loved the sweet and salty combo. As always, great post!
[Reply]
YUM YUM YUM!!! I can’t get enough sweet potatoes!!!
[Reply]
Mmmmmm…I couldn’t wait to try this as soon as I read the post! Totally hit the spot last night! It’s on my “go-to” list now…thanks!
[Reply]
Hi Emily,
I just made this dish for lunch and it was delicious! The sauce is magical! I poured it over sweet potatoes, roasted carrots, mushrooms and spinach. Thank you for a great recipe :)
[Reply]
Hi Emily,
your last post inspired my to bake some pear-ginger-muffins, thanks. I really like your site as I am pretty much into running at the moment and can get a lot of motivation and tipps here!
Greetings from Europe,

…you made this batch with 4 sweet potatoes and Cullen ate half of it? Plus tofu and avacado? Am I reading that right? They must have been small potatoes or your little man has a monster appetite!! Looks yummy :)
[Reply]
I just made this for an afternoon snack and it is delicious! I am a big fan of tahini so I knew it was a recipe with priority. Thank you so much for sharing!
[Reply]
I just made a batch of this, put some on some roasted sweet potatoes I already had in the fridge, then tossed a bunch of kale leaves in some more and baked them into kale chips. In other news, I just ate an entire bunch of kale. By myself. Dang.
[Reply]
I made this for dinner today, and it was DELICIOUS!!
[Reply]
I made this for dinner last night, and I have to say – I’m glad I followed my gut and doubles the sauce and have LOTS left over – it was so delicious I was eating it with everything while my sweet potatoes were roasting. kale chips, crackers, celery! Delicious!
[Reply]
Hi! This looks delicious and I can’t wait to make it. Where do you buy the chick pea miso? We don’t have a Trader Joe’s in my neck of the woods. I have a soy allergy and was so excited to see that this is soy free.
[Reply]
I’ve never had miso, I think…?Is it the same as miso soup?Sorry for being a bit ignorant…
On another note, I hope you’ve decided on the milk for Cullen.Can’t wait to read your “review” for that.I love your blog- I like to come here and drool!
[Reply]
Thanks for posting this, Emily! Was definitely worth the wait :) I made the sauce last night and put it on top of roasted kabocha, quinoa and sauteed mushrooms and kale. It tasted great!
[Reply]
I made this tonight. Ho-leee smokes. My only experience with miso is having the miso soup at sushi joints. Well I am sad that I have missed out on using it for an ingredient for so long! This is simply amazing.
[Reply]
I just finished eating these potatoes, paired with blackened tofu. Delicious!! And so easy! This was the first time I have ever tasted miso and it was so unique, thanks for another great recipe!

I wanted to let you know I made these last night for a family dinner and everyone loved them! That sauce is magical and paired with the sweet taters…perfection!
I have a bunch leftover so I’m thinking of making a roasted sweet potato/miso baked pasta. Thoughts?
[Reply]
We made this tonight and it was delicious! I am a big fan of the other miso tahini sauce recipe you have (I think it went on pasta with mushrooms and zucchini but I eat it on anything). We have some leftover sauce, so I went out and bought more sweet potatoes for another meal.
I was just curious- at what age did you introduce tahini to Cullen? We have an almost 8 month old son and I’m trying to find some info about when to introduce sesame/tahini. I can’t find it anywhere (not even Wholesomebabyfood)!
[Reply]
Trying this miso sauce with my 10 month old picky eater – I’m hoping she’ll be as enthusiastic as Cullen was!
[Reply]
I had this starred in my reader since you posted it and just got around to making it last night. It was amazing!! I also put the miso sauce on a simple salad and that worked well, too. Thank you so much for all your amazing recipes!!
