Ingredients You’ll Need
Gathering just a handful of simple, essential ingredients is all it takes to create these mouthwatering mochi snacks. Each component plays a distinct role, from the creamy potatoes providing the base, to the glutinous rice flour giving that signature chewy texture, and the hint of soy sauce adding a savory depth that keeps you coming back for more.
- 1 pound russet potatoes: The starchy potato that yields a smooth, fluffy mash perfect for forming mochi.
- 1/2 cup glutinous rice flour (mochiko): This special flour creates the wonderfully chewy texture that defines mochi.
- 1/2 teaspoon salt: Enhances the natural flavors of the potatoes and balances the sweetness.
- 1 tablespoon sugar: Adds a subtle sweetness that rounds out the flavor beautifully.
- 2 tablespoons unsalted butter, melted: Provides richness and a silky smooth texture in the dough.
- 1 tablespoon soy sauce: Used for pan-frying, it gives each mochi a savory, umami-packed glaze.
- 1 tablespoon neutral oil: Essential for frying to get that perfect crispy exterior without overpowering flavors.
- Optional toppings (shredded nori, sesame seeds, scallions): Add crunch, color, and extra layers of taste when served.
How to Make Potato Mochi Recipe
Step 1: Boil and Mash the Potatoes
Start by boiling your peeled and chunked russet potatoes in salted water for about 10 to 12 minutes until they are fork-tender. This part is key because well-cooked potatoes ensure your mochi is silky rather than lumpy. Once done, drain thoroughly and mash them while still warm, creating a smooth and slightly fluffy base for your dough.
Step 2: Mix in the Mochiko and Flavorings
While the potatoes are still warm, it’s time for the magic moment. Add the glutinous rice flour, salt, sugar, and melted butter to the mashed potatoes. Gently fold everything together until you form a soft, pliable dough. The warmth helps the ingredients meld beautifully, creating a dough that’s just right — not too dry and not sticky.
Step 3: Shape Into Discs
Next, divide the dough into 6 to 8 equal portions depending on your desired size. Roll and flatten each portion into a disc about half an inch thick. This size lets the mochi cook evenly, achieving a crispy golden crust while keeping the inside tender and chewy. The shaping is half the fun, so enjoy the tactile experience!
Step 4: Pan-Fry to Golden Perfection
Heat a nonstick skillet over medium heat and add your neutral oil. Carefully lay the mochi discs into the pan and fry each side for 3 to 4 minutes, until they develop a gorgeous golden brown color and a satisfying crisp. During the last minute of cooking, brush the tops lightly with soy sauce for that extra punch of savory flavor that makes these snacks utterly addictive.
How to Serve Potato Mochi Recipe

Garnishes
Topping your potato mochi with things like shredded nori, sesame seeds, or finely sliced scallions elevates the dish from simple to spectacular. These garnishes add delightful texture, a pop of color, and nuanced flavors that complement the savory-sweet mochi beautifully.
Side Dishes
Potato mochi pairs wonderfully with a light miso soup or a crisp green salad for a balanced meal or snack. If you want to keep the Japanese vibes going, soy sauce-dipped vegetables or pickled side dishes create lovely contrasts and make a fun sharing platter.
Creative Ways to Present
For a playful twist, try serving your Potato Mochi Recipe stacked like mini pancakes, drizzled with a sweet soy glaze or paired with a dollop of spicy mayo. You can also skewer them as bite-size appetizers at gatherings, adding a sprinkle of furikake or bonito flakes for an unforgettable presentation.
Make Ahead and Storage
Storing Leftovers
If you have some mochi pieces left over, wrap them tightly in plastic wrap and store in the refrigerator for up to 2 days. Keeping them sealed prevents the chewy texture from drying out and helps retain their tender bite.
Freezing
You can freeze uncooked shaped mochi discs by laying them on a parchment-lined tray and freezing until solid. Transfer them to a freezer bag, and when ready to enjoy, thaw slightly before pan-frying. This is perfect for making in batches and enjoying anytime.
Reheating
To bring leftovers back to life, reheat the mochi in a hot skillet or an air fryer. This restores the crispy exterior and warms the inside just right. Avoid microwaving, as it tends to make them chewy or rubbery instead of delightfully crispy.
FAQs
What kind of potatoes work best for Potato Mochi Recipe?
Russet potatoes are ideal because their starchy nature results in a smooth mash, which helps the mochi hold together and achieve a soft, chewy texture after frying.
Can I use other flours instead of glutinous rice flour?
Glutinous rice flour is essential for that classic stretchy, chewy mochi texture. Using other flours will change the consistency and likely won’t give you the same satisfying bite.
Is Potato Mochi Recipe gluten-free?
Yes, as long as you use gluten-free soy sauce or tamari, this recipe is gluten-free because it relies on glutinous rice flour instead of wheat.
How sweet or savory should the Potato Mochi be?
The balance is subtle: a touch of sugar softens the flavor without making it overly sweet, while soy sauce adds a nice savory glaze. You can adjust the sugar level to your liking for a sweeter treat.
Can I bake Potato Mochi instead of pan-frying?
Baking may not yield the same crispy, golden crust that pan-frying does, but it’s possible if you brush the mochi discs with oil and bake at a high temperature. Just know the texture will be a bit different.
Final Thoughts
This Potato Mochi Recipe is a delightful way to reinvent a common ingredient into something uniquely satisfying and immensely comforting.
