Ingredients You’ll Need
The magic of the Potato Mochi with Soy Glaze Recipe lies in its straightforward, humble ingredients. Each one plays an essential role, layering flavor, texture, and color to bring this dish to life without any fuss or complicated elements.
- Russet potatoes (2 medium, peeled and cubed): The starchy base that gives these mochi their tender, chewy texture.
- Potato starch (1/4 cup): Helps bind the potatoes into a soft but pliable dough for shaping.
- Salt (1/4 teaspoon): Enhances the natural flavors of the potato and balances the glaze.
- Soy sauce (1 tablespoon): Brings a rich, savory depth to the glaze that latches perfectly onto the mochi.
- Mirin (1 tablespoon): Adds a gentle sweetness and a glistening finish to the glaze.
- Sugar (1 tablespoon): Rounds out the glaze with just the right touch of sweetness.
- Vegetable oil (1 tablespoon): Essential for pan-frying and achieving that perfect golden crust.
- Optional garnishes – toasted sesame seeds or chopped scallions: Add a fresh crunch and a pop of color on top.
How to Make Potato Mochi with Soy Glaze Recipe
Step 1: Boil and Mash the Potatoes
Start by boiling the peeled and cubed russet potatoes in salted water until they are fork-tender, which usually takes about 10 to 12 minutes. This step ensures your potatoes become tender enough for smooth mashing. Once done, drain them well and mash until completely smooth. This smooth base is the heart of your mochi, so take care to avoid any lumps for the best texture.
Step 2: Form the Mochi Dough
While the mashed potatoes are still warm, add the potato starch and salt. Mix everything together thoroughly until the starch is fully incorporated and the mixture comes together into a soft, pliable dough. This step is key because the potato starch binds everything without making the mochi heavy, giving that signature chewy bite.
Step 3: Shape the Mochi Patties
Divide the dough into 6 to 8 even portions and shape each piece into a small round patty. Aim for uniform thickness across each patty to ensure they cook evenly and achieve a consistent golden crust. These little patties are what transform simple potatoes into a fun, hand-held snack.
Step 4: Pan-Fry until Golden
Heat the vegetable oil in a nonstick skillet over medium heat. Carefully place the patties into the hot pan and cook for 3 to 4 minutes on each side, or until they develop a crisp, golden-brown exterior. This frying step is what brings a delightful contrast between the crunchy outside and the chewy inside—absolutely delicious!
Step 5: Prepare and Add the Soy Glaze
While the mochi cooks, mix the soy sauce, mirin, and sugar in a small bowl until the sugar dissolves and the glaze is smooth. After pan-frying, pour this glaze directly into the pan and cook for another minute, flipping the mochi to coat both sides evenly. This step locks in that beautiful shiny finish and infuses every bite with a sweet-salty punch.

Garnishes
Naturally, a sprinkle of toasted sesame seeds or finely chopped scallions brings extra texture and bursts of flavor that beautifully complement the glazed mochi. These simple garnishes elevate your presentation while introducing subtle nutty or fresh notes that keep each bite exciting.
Side Dishes
Potato Mochi with Soy Glaze Recipe is incredibly versatile and pairs beautifully with light side dishes like a crisp cucumber salad or steamed edamame for a refreshing balance. For heartier options, consider serving it alongside miso soup or a bowl of pickled vegetables—these help round out the meal with contrasting flavors and textures.
Creative Ways to Present
Get playful by serving these mochi on small bamboo trays or skewer a few on elegant toothpicks to create bite-sized party snacks. You can also offer a dipping sauce made from a blend of soy sauce and rice vinegar on the side for an interactive dining experience that delights both eyes and palate.
Make Ahead and Storage
Storing Leftovers
If you’re lucky enough to have leftovers, place the mochi in an airtight container and store them in the refrigerator for up to 2 days. Keep in mind that the crispy exterior will soften, but they’ll still taste great when reheated thoughtfully.
Freezing
To freeze, arrange the mochi patties on a baking sheet without touching and flash freeze until firm. Then transfer them to a freezer bag or airtight container. They’ll keep well for up to 1 month, allowing you to enjoy your Potato Mochi with Soy Glaze Recipe any time you crave a quick, flavorful snack.
Reheating
For a crispy finish after storing, reheat the mochi in a lightly oiled skillet over medium heat until warmed through and crisp on the outside again. Avoid microwaving if you want to preserve that satisfying crunch that makes this recipe so special.
FAQs
Can I use sweet potatoes instead of russet potatoes?
While sweet potatoes can be used, they have a higher moisture content and different starch composition, which may alter the chewy texture of the mochi. Russet potatoes are ideal for that signature chew and crisp crust.
Is there a gluten-free alternative for soy sauce?
Absolutely! Simply swap regular soy sauce with tamari or a certified gluten-free soy sauce to keep this Potato Mochi with Soy Glaze Recipe entirely gluten-free without sacrificing flavor.
How do I make the mochi more chewy?
Adding a bit more potato starch to the dough helps enhance chewiness. Just be cautious not to add too much, or the mochi may become too dense.
Can I bake the mochi instead of pan-frying?
While pan-frying gives the best crisp, you can bake them at 400°F (200°C) for about 15-20 minutes, flipping halfway. The texture will differ slightly, but it’s a great hands-off option.
What should I serve the mochi with for dipping?
A simple dipping sauce made of soy sauce mixed with a bit of rice vinegar or chili oil makes a perfect companion. It adds a tangy or spicy kick and pairs wonderfully with the savory glaze.
