Isobe-Yaki Potato Mochi じゃがいも 磯辺焼き
Description
Soft, chewy and delicious potato mochi entangled in a sweet soy sauce. The perfect quick, healthy and easy snack or side dish!
Ingredients
Potato Mochi
- 1 large potato, cooked potatoes (290g // with skin on, cooked and peeled after)
- 2 tbsp potato starch (25g)
- 2 tbsp of milk, as needed (30ml)
- 1 tbsp vegan butter
- Nori for wrapping
Sauce
- 2 tbsp soy sauce 30ml
- 2 tbsp sugar 25g-g
- 1 tbsp mirin 15-25g
- 1 tbsp sake (or sub more mirin, it will be slightly more sweet)
Instructions
- Microwave the potatoes with a damp paper towel around it at 600 W for 5 minutes or until soft. Allow potato to cool.
- In the mean time, mix all the sauce ingredients together. Cut small rectangles of nori to wrap the potato mochi.
- Once potato are cooled, remove skin and mash. Mix in the potato starch and non-dairy milk little by little. Adjust amount accordingly depending on moisture of potato. It should stick together to form patties but not be too wet or sticky. Divide into about 60g pieces and then shape them into circles.

- Remove excess oil if there is. Stop the heat and then add the sauce, and cook until it thickes. Coat potato mochi with sauce and wrap with nori. Add cheese in the middle if desired

Hi Lisa,
I hope this finds you well. You Isobe-Yaki Potato Mochi has become a favorite in our home. Thank you for sharing it with the world.
I am looking forward to making this for our close friends visiting and was curious if the mochi could be made the day prior to frying. Any thoughts or insight would be beyond appreciated.
Thank you!
These were wonderful! So simple to make and the sauce was just amazing and delicious. Thank you for the recipe. This is definitely going to be one of my all-time favorite things to make.
Perfect recipe this was so easy and delicious!
I love these so much! I come back to them again and again as they’re just so simple to make quickly as a snack or side dish.
Make these!! I was intimidated to try making these but they’re SO easy and SO delicious~ とてもおいしいですね!It is such a nice and warming thing to share with friends/family too!! They were even delicious the next day!
Thank you for a new dish that will probably be served at our table for years to come. Super yummy, kid friendly recipe. We baked the potatoes in the oven because we made enough to feed 15 people and added spring onion to the mix. They were a hit. We substituted soy sauce with coconut aminos and wished we’d made twice as much. Topping the mochi with Nori furikake was probably the best adjustment to the recipe ad the added cruch and flavor profile made these a new family favorite. Delicious.
Thank you so much for the recipe, we really loved it. I ended up not having potato starch, so I tried both sweet rice flour and arrow root starch. We ended up liking the arrowroot a lot better, as it was actually really chewy. Again, have not tried it with the potato starch but the arrowroot starch gives it a great texture!!
Thanks again!
These are really good! That being said (and I’m not sure if it’s because this is how they’re supposed to be, or if I did something wrong — didn’t thicken the sauce enough, messed up the proportions somehow, etc), but they were kind of just… mashed potato patties fried in butter, covered with a sweet sauce. They weren’t chewy or mochi-like at all. They still tasted amazing, though, since it’s hard to go wrong with fried potatoes (and the sauce is incredible)!
I was inspired to make this recipe by the new Pokemon Arceus game, and they were just as tasty and comforting as they look in the game! This recipe was also so simple to make, although I do recommend using a nice thin spatula to get the first flip perfect. Also – if your glaze doesn’t seem to be thickening enough, let it cool for a few minutes and it will get thicker. I’ll definitely make these again!
I made these for a TikTok video and the video was a huge hit, so thank you! They’re also delicious, so thanks for that too! I didn’t have potato starch, mirin, or sake, so I used cornstarch and rice vinegar, which turned out amazing!

This recipe was so easy to put together and tasted delicious! I went to Hmart for the potato starch and mirin and both were super easy to find. Really glad to have these ingredients on hand as they open up some other recipes for me to try too 😋 I loved the potato both and without the nori. Crispy on the outside and still sooo soft inside, honestly 10/10 it’s the perfect potato snack 💓
I’ve just done it and its delicious! and absolutely easy to make, I really recommend!. Also, I’m wondering what to serve them with as the best option, any recommendations? 🙂
Absolutely delicious little starchy delights!
I think I had a giant potato because my patties came out huge! If this happens to you I recommend simply making them smaller (hey, you get more that way!)
I unfortunately didn’t have vegan cheese on hand so I simply omitted it, but next time I will definitely be sure to have some!
Thank you for another killer recipe!
This is an original way to cook potatoes and I love it so much! It’s is tasteful and the texture is really nice
I loved them!
Made them today. So incredibly delicious and soft and crispy at the same time. I’ll be making them more often from now on.
Loved this recipe. Very easy to make and was very delicious and flavorful. The sauce was a perfect edition for the potato. Made this as a side dish for my husband and he loved it as well.
Taste really good !
These were super simple to make and so delicious!! The sauce is perfect. I felt weird not seasoning the potatoes before pan frying but the sauce gives it all the flavor it needs. My partner and I made them three times in a week, and we’ve put ourselves in potato jail.
I loved these little things, you can just keep eating it! And I loved the hint of sweetness it had!
I already love potatoes but this made me love them even more, super tasty!
I made these today, doubling the recipe. Instead of soy sauce, I used coconut aminos and decided against using sugar. It was delicious!!!
Super easy to make and they turned out delicious! Crispy on the outside and soft and chewy on the inside. The nori gives it a nice salty umami flavor which really makes the dish
Literally so delicious and beautiful!!! They’re easy af to make too. They weren’t heavy and greasy that make you feel sick after eating them as well which I really appreciate. They were perfect – not too sweet or salty, lightly fried, and beautiful! I got so many people praising them and asking for the recipe. Definitely a new staple! <3
A quick and delicious way to take potatoes to the next level! These are now a family favorite 🙂
Made these as snacks for some friends on game night and they loved them. The recipe was quick and easy, definitely making these for others to try.
Me and my girlfriend love this recipe. It’s quick easy and super tasty. We’ve been trying more vegan recipes and Japanese food is a our favorite and once we found Lisa’s Instagram page we were hooked.
Thank you so much for this recipe. It was pretty easy and super tasty.
It was the very first time I cooked vegan!
I love all of your recipes ~
this recipe is so easy! vegan, comforting, and a great way to start the morning! the way the sauce coats the mochi is incredible
i didn’t have potato starch or sake so i used more mirin and tapioca flour instead. they came out amazing! i will be adding potato starch to my pantry tho i’m sure it makes it even better!! 10/10 my new fav morning recipe
Easy and delicious!! I loved it a lot. I will make this for my family as well 😀
Easy and delicious!! I loved ir
These are so quick, easy, and delicious!!
Lisa’s insta always gets me trying new recipes and I’m so glad she does. These potato mochi are so satisfyingly crunchy and soft at the same time; sweet & salty on the surface and melt in your mouth potato goodness at the centre. I’ve found par-boiling the potatoes works just as well especially if your microwave isn’t as powerful (also you can peel them first this way to avoid burning your fingers). I first made these at a friend’s with a gas cooker and they came out perfectly, had to try a few times to get the same results back home with electric so make sure to get the pan nice & hot to get that sizzling crunchy caramelised exterior. Could eat these everyday.
We freaking love love love them 😍
They are pretty easy to make and taste just amazing^^
Thanks 🌱✌🏻
Such a tasty and quick recipe! ^_^ いただきます!
I love it! Recipe is so good and easy.
Definitely will cook it again!
such an amazing recipe, mine turned out a little soggy but i think that was my fault.
It was not easy to me, but the taste is really good✨✨✨
these are so yummy! made them as a snack for me and my hubby. easy to make. it’s one of those things you try to eat only 1 or 2 pieces but you just can’t help yourself lol
made this a few times already coz it’s so easy & oishiiii!!
INCREDIBLE!! First time making mochis and loved it. It was so simple, love the recipe!
I tried this recipe and it’s the bomb! So simple yet so good! It was my first time cooking a potato in the microwave oven but turned out perfect for this recipe. My partner also loved it!
Delicious! The classic Japanese flavours make this potato-based snack a real treat, especially when I’ve got some extra potatoes lying around. 10/10 will make again!
such an easy recipe to make and makes good use of leftover potatoes or sweet potatoes!!
So fun to make! Honestly, it was really easy, and you can also put cheese in the potato balls too for that gooey effect! It was salty, savory, and slightly chewy and it made a fun meal for everyone in my family to eat. I will for sure find the time to make this again and everyone else should do too!
So easy. So yummy. Also easy to adjust to however much potato you have sitting around! I made it for a quick snack and it’s delicious! Used olive oil instead of butter. Will be making again and adding cheese!
OH EM GEEEEEE GUYS! This one was a banger! If you love potatoes as much as me then you have to try this one out. Actually super simple and incredibly delish. Must-have recipe for sure! Thank you Lisa, you’ve done it again!
Lisa pls this is so hood and addictive and packed full with wonderful flavors thank you so much for sharing it with us 💜💜💜💜💜
This recipe was absolutely amazing! Except for boiling the potatoes (mine were apparently quite tough), the recipe is really quick and easy. I didn’t use butter, but vegetable oil worked fine too. Absolutely 10/10 making it again 😀 maybe I’ll try variations like with chili flakes, sesame seeds, something like that!
These are amazing!! Made them w/ cornstarch and sweet rice flour 2 different times and both were great subs for potato starch since I didn’t have any. So flavorful, chewy, and easy to make!
My bf loved it. They taste kind of like plantains.
These turned out so good!! I modified the sauce recipe slightly and used coconut aminos instead, but otherwise followed the recipe exactly. I can’t wait to try it again!
Ever since I tried this dish. I must eat it at least once a week!! It’s so tasty I can’t get enough of it!
Made a substitute of Cornstarch and it worked wonders!! The sauce was brilliant too and gave the Mochi such a nice taste.
I’ve made these twice in a week. These potato mochis are so easy to prepare and incredibly addictive. I love potatoes and these smell so amazing while cooking in a pan. I’m obsessed with the texture of them too! The 2nd time I made them I didn’t make the teriyaki sauce. They were delicious plain.
This recipe is amazing! Even my boyfriend who doesn’t like sweet sauce very much loved it
It was sooo fire.. Inspite of having some trouble and some need for substitutes it was delicious🤤
Delicious!
Amazing recipe! Super easy way to use up cooked potato. I used a mix of regular white and orange sweet potato and it was veryyy nice indeed. Would really recommend trying this… the sauce is so sweet and tasty! Good with steamed rice abs spring onions too.
These were so nice! I added some kewpie mayo and sriracha on top, it really was that kind of food that brings you instant joy! ❤️
This recipe was so simple and easy, and absolutely delicious! I didn’t have sake, so I doubled down on the mirin, and am excited to see how the flavor changes with sake instead. I also tried these with a little chili oil and sriracha, and it was just *chefs kiss*.
These turned out so yummy. I made them with my nine year old daughter and they were really easy.
Soooo goood, the texture is amazing !
These were delicious! Pretty simple to make and veryyy yummy.
So easy and delicious! Great way to use up extra potatoes. Will definitely make again!
Ultimate soul food! Can’t wait to make this again and just giggle with joy! So good!
Easy and delicious. Can’t wait to make more.
It is dangerous how delicious this is. Before you know it they’re all gone! Very relaxing to make and can be paired with pretty much anything. I really can’t wait to make this for my friends!
Just made these! Super tasty ~ will definitely make them again and probably make the patties smaller next time.
Thanks! 🙏🏼
This are really good!!! And super easy. Also I added garlic to the potatoes and 🤤🤤
Nice, delicous ans simple recipe. ♡♡♡
Ok ngl, I think this is my favorite recipe from you so far🙊it’s easy to make and sooo delish. It’s crispy on the outside and gooey in the inside…and the sugar caramalizes to make this delicious exterior. I also finally invested in some mirin which has been an absolute game changer. 11/10
Super easy and delicious recipe, I tried it today for the first time and everyone liked it!!💞💞
made this for my family and they all loved it!! will definitely make them again!<3
It was sooooo tasty!!
Also, very easy to do!
I will definitely try them out again!! Thank you❤️
This recipe was perfect! Quick and easy and tastes great! I had to leave the heat on the sauce for a few minutes longer to get it to thicken but it came out great!!!
Ok…I should start off by saying I’m a terrible cook and I managed to make this and it was delicious!!! I can’t believe I was able to successfully make this because there’s always a 70% chance of failure when I try new recipes. I cannot wait to try out the other ones!!!!!
Love that the recipe is quick and easy to make with just a few simple ingredients! Super flavourful and highly addictive! Not only did I like it, but my siblings did too! Will definitely make again! 😋💖
Made this yesterday and it was sooo good!! So yummy and comforting, and the perfect mix of sweet and salty!! Definitely try it out🥰
Made these the other day. Can’t stop thinking about them. So easy and so yummy! The perfect snack/side dish. Thanks for sharing the recipe, Lisa!
Really tasty recipe and so quick to make!
Amazing!! I was worried I would mess it up with cooking the potato in the microwave (I fail at some simple things! Ha) but I saw Lisa say to someone on Instagram that the potato can be boiled. So I boiled it to be on the safe side, then followed the rest of the recipe as above. I don’t have sake so used the extra mirin option. These are really easy to make and so delicious. Will be making these a lot! Thanks for sharing this! X
Delightful little balls of yum! We put cheese in the center and it was the perfect complement to these delicious mochi.
I very love this manu it look cute and yummy 💕 and fun for cook it !!
Delicious and very easy to make
Really delicious comfort food <3
This recipe was easy and so delicious! I loved the sweet glaze, will definitely be making these again! Thank you for sharing this recipe!
I found it easier to grate the potatoes rather than mash it. Other than that, I followed the instructions precisely (I didn’t have sake so added in extra mirin) and it was delicious! I’m thinking of using the leftover sauce on some grilled onigiri!
Made it today 5/10/21 and can i just say its hands down now one of my favorite foods. Its so good
This recipe is delicious and so easy to make! I didn’t have nori when I made these but will definitely make them again with the nori pieces. I dipped mine in a tiny bit of sriracha and omg they were so good. Thanks for sharing this great recipe! Can’t wait to try more 🙂
BRB going to eat this forever
The potato version is SO DELICIOUS especially for people who dont like yam or sweet potatoes ect.! Such a simple side to add to your dinner. #vegan
Such a comforting, delicious snack! Insanely simple to prepare, and cute handheld presentation. The sauce…I don’t even have words. I reserved the extra portion for “dipping” but more realistically, will be drinking sips of it straight from the dish all night that’s how addictive it is.
Loved it al lot, thank you so much for sharing this recipe with us! I am a huge fan of mochis, and this was quite cool to make for a first time!
These mochi are just wonderful, quite quick and easy to make and incredibly yummy,they’ve just become one of my staples!
So easy, so addicting, so good!
Sooooo good! Your videos inspired me to try new things in the kitchen and I decided to start with this one bc I just so happened to have the ingredients. Such a great decision!!! I filled it mine with Daiya cheddar cheese slices and it was THE BEST. Gonna make this tomorrow for the whole family <3
They were quickly done and tasted sooo good!
Very cool and easy recipe 👍 I made them yesterday. Very delicious.
I made these today and they were so delicious! The potatoes were crisp and soft on the inside. And the sauce was sweet and sticky the perfect combination. These will definitely be a new method of preparing my potatoes from now on! They are easy to make and so delectable! 😋
These are delicious 🤤, I’ve just made it. Yami yam! 🙏 Thank you!
