- 2 tablespoons milk: Adds creaminess to the dough, making it soft and easier to work with.
- 2 tablespoons butter: Used both for cooking and coating to give a silky, rich finish.
- 1 tablespoon soy sauce: Brings umami depth and a touch of saltiness to the glaze.

How to Make Potato Mochi Recipe
Step 1: Prepare the Potatoes
Begin by peeling and cutting the potatoes into chunks for even cooking. Boil them in salted water until tender, usually about 12 to 15 minutes, then drain thoroughly. Mashing the potatoes until perfectly smooth is key to the ideal mochi texture, so take your time to eliminate lumps.
Step 2: Form the Mochi Dough
Next, combine the mashed potatoes with potato starch, salt, and milk. This mixture will form a soft dough that’s pliable and ready to shape. Be sure to mix until all ingredients are fully incorporated for consistent texture throughout.
Step 3: Shape the Patties
Divide the dough into small, even portions and roll each into a round patty about 2 inches in diameter. This size allows for quick cooking while still delivering a satisfying chewiness that’s not too overwhelming.
Step 4: Fry to Golden Perfection
Heat the vegetable oil in a skillet over medium heat, then carefully place the patties in. Fry them for 3 to 4 minutes per side until they develop a gorgeous golden brown crust that adds delightful contrast to the chewy center.
Step 5: Glaze and Finish
While the patties cook, stir together the soy sauce, sugar, and mirin in a small bowl. Pour this glaze into the skillet toward the end of frying and let it bubble for about one minute, turning the mochi to ensure they’re evenly coated. Lastly, add the butter and gently toss the patties to coat them with a rich, buttery finish before removing from heat.
How to Serve Potato Mochi Recipe

Garnishes
Potato mochi is wonderfully versatile when it comes to garnishes. Try sprinkling toasted sesame seeds for a nutty crunch or finely chopped scallions to add a fresh, bright touch. A small drizzle of extra soy sauce or a touch of Japanese mayo can also elevate your serving effortlessly.
Side Dishes
This dish pairs beautifully with lighter sides such as a simple cucumber salad dressed with rice vinegar or a bowl of clear miso soup. The fresh vegetables and warm broth balance the richness and chewiness of the mochi harmoniously.
Creative Ways to Present
Want to impress at your next gathering? Serve the potato mochi on wooden skewers for a fun, bite-sized appetizer. Alternatively, arrange them atop a bed of steamed greens or alongside pickled ginger to create colorful, appetizing plates that invite conversation.
Make Ahead and Storage
Storing Leftovers
If you have any leftover Potato Mochi Recipe patties, store them in an airtight container in the refrigerator. They’ll stay fresh for up to 2 days, making for a quick snack or addition to meals the next day.
Freezing
You can freeze uncooked shaped mochi patties by placing them on a parchment-lined tray and transferring to the freezer until solid, then moving them to a sealed bag or container. Frozen, they’ll keep well for up to a month and can be cooked straight from frozen with a slightly longer frying time.
Reheating
To reheat, gently pan-fry the mochi patties over medium heat to restore their golden crisp outside and soft, chewy center. Avoid microwaving as it may alter the texture and make them rubbery.
FAQs
Can I use regular flour instead of potato starch?
Potato starch is crucial for the distinctive chewy texture of the mochi, so substituting with regular flour will create a different, less authentic result. For the best outcome, stick to potato starch.
Is it possible to add fillings to the potato mochi?
Absolutely! Adding a small cube of cheese or seasoned vegetables inside the patties before frying can create a delicious surprise, adding richness and flavor variety to your Potato Mochi Recipe.
How do I know when the mochi patties are cooked perfectly?
Look for a golden brown crispness on both sides and a slight firmness when gently pressed. The inside should be soft and chewy without being mushy.
Can I make this recipe vegan?
Yes! Simply replace the butter with a plant-based alternative and use a vegan-friendly soy sauce. The rest of the ingredients are naturally vegetarian and vegan-friendly.
What’s the best way to serve Potato Mochi at a party?
Serve them warm on toothpicks or small plates with dipping sauces like a spicy mayo or extra soy glaze. Their bite-sized nature makes them perfect for sharing and snacking.
