How to Make Potato Mochi Recipe
Step 1: Boil and Mash the Potatoes
Start by boiling the peeled and chopped russet potatoes in salted water until they become fork-tender, about 15 minutes. This ensures they are soft enough to mash smoothly, which is essential for forming the perfect mochi dough without lumps.
Step 2: Combine Ingredients to Form Dough
Once the potatoes are drained, mash them thoroughly while still warm, aiming for a smooth consistency. Let the mash cool slightly before stirring in the potato starch and salt. You’ll notice the mixture transforming into a soft and pliable dough that’s just right for shaping.
Step 3: Shape Your Mochi Discs
Divide the dough evenly and shape each portion into small flat discs, roughly 2 inches in diameter. This size is ideal to get the perfect balance of chewy interior and golden crust when pan-fried.
Step 4: Prepare the Sweet-Savory Glaze
Mix the soy sauce, mirin, and sugar in a small bowl until the sugar dissolves. This glaze will create that signature glossy finish and a lovely layer of flavor on your mochi.
Step 5: Pan-Fry to Golden Perfection
Heat the vegetable oil in a nonstick skillet over medium heat. Carefully place your mochi discs into the pan and fry for 2 to 3 minutes on each side until they turn a gorgeous golden brown. The key here is not to rush, giving the outside time to crisp while the inside stays chewy.
Step 6: Glaze and Caramelize
Brush both sides of the fried mochi discs with the soy sauce glaze, then cook for an additional 1 to 2 minutes, allowing the glaze to caramelize gently. This step elevates the flavor and adds a sticky-sweet finish that’s absolutely addictive.
How to Serve Potato Mochi Recipe

Garnishes
A sprinkle of shredded nori or toasted sesame seeds adds an inviting aroma and a delightful textural contrast to your Potato Mochi. These garnishes also lend a touch of Japanese authenticity and visual appeal that makes every bite more enjoyable.
Side Dishes
Serve your mochi alongside light, fresh options like pickled vegetables, steamed greens, or a simple miso soup to create a well-rounded snack or meal. The balance of textures and flavors keeps the palate refreshed between bites of chewy, glazed mochi.
Creative Ways to Present
If you’re hosting, arrange the mochi discs on a wooden board with small bowls of extra glaze, chopped scallions, or spicy mayo for dipping. You can also stuff the mochi with melted cheese or seasoned veggies before frying for a surprising and fun twist that your guests will rave about.
Make Ahead and Storage
Storing Leftovers
Leftover Potato Mochi should be stored in an airtight container in the refrigerator. They hold up well for up to two days without losing their texture or flavor, making them an easy snack to enjoy later.
Freezing
For longer storage, flash freeze individual mochi discs on a baking tray before transferring them to a freezer-safe bag or container. This prevents sticking and ensures you can enjoy the Potato Mochi Recipe anytime, frozen for up to one month.
Reheating
Reheat your mochi by pan-frying them again briefly in a little oil to restore that crispy exterior. Alternatively, a quick microwave zap works in a pinch, but frying will always give you the best texture and flavor.
FAQs
Can I use sweet potatoes instead of russet potatoes for Potato Mochi Recipe?
Absolutely! Sweet potatoes offer a naturally sweet flavor and beautiful color that works wonderfully in this recipe, just be mindful they may require slightly less starch since they can be moister.
Is it necessary to use potato starch, or can I substitute cornstarch?
You can substitute cornstarch if that’s what you have on hand. Potato starch tends to give a chewier texture, closer to traditional mochi, but cornstarch will still yield delicious results.
How do I make Potato Mochi vegan?
This Potato Mochi Recipe is already vegetarian, and to keep it vegan, simply ensure your soy sauce and mirin are vegan-friendly and avoid adding any cheese or non-vegan fillings.
What can I do if my mochi dough is too sticky or too dry?
If it’s too sticky, gradually add a bit more starch until the dough becomes manageable. If it’s too dry and crumbly, fold in a tiny splash of water or a little extra mashed potato until it feels smooth and pliable.
Can I bake instead of pan-frying Potato Mochi?
While pan-frying gives Potato Mochi its characteristic crispy crust, baking is possible. Brush the mochi with oil and bake at 400°F (200°C) until golden and crisp, turning halfway through. The texture will be less oily but still tasty.

This Potato Mochi Recipe is the perfect little celebration of simple ingredients coming together to create something exceptionally comforting and delicious.

Ingredients
Main Ingredients
- 2 medium russet potatoes (about 1 pound), peeled and cut into chunks
- 1/4 cup potato starch or cornstarch
- 1/4 teaspoon salt
Glaze
- 1 tablespoon soy sauce
- 1 tablespoon mirin
- 1 tablespoon sugar
For Cooking
- 1 teaspoon vegetable oil (for pan-frying)
Optional Toppings
- Shredded nori
- Sesame seeds
Instructions
- Boil Potatoes: Boil the peeled potato chunks in salted water until they become fork-tender, about 15 minutes. Properly drain the potatoes to remove excess water.
- Mash Potatoes: Mash the drained potatoes thoroughly until smooth and lump-free. Allow the mashed potatoes to cool slightly to avoid premature gelatinization of starch.
- Make Dough: Incorporate the potato starch and salt into the mashed potatoes. Mix well until a soft, pliable dough forms, which should hold together without being sticky.
- Shape Mochi: Divide the dough into equal portions and shape each into small, flat discs approximately 2 inches in diameter. This size ensures even cooking.
- Prepare Glaze: In a small bowl, combine soy sauce, mirin, and sugar. Stir until the sugar is dissolved to create a smooth glaze.
- Heat Oil: Warm the vegetable oil in a nonstick skillet over medium heat to prepare for pan-frying.
- Pan-Fry Mochi: Place the mochi discs in the skillet and fry for 2 to 3 minutes on each side. Cook until the exterior is golden brown and develops a crispy texture.
- Apply Glaze: Brush the glaze generously on both sides of each mochi disc. Continue cooking for another 1 to 2 minutes, allowing the glaze to caramelize slightly, imparting a glossy, flavorful coating.
- Serve: Serve the potato mochi warm. Optionally, garnish with shredded nori or sprinkle with sesame seeds to enhance flavor and presentation.
Notes
- For a chewier texture, opt for potato starch rather than cornstarch as it provides better elasticity.
- You can stuff each mochi disc with cheese or seasoned vegetables before pan-frying for a delightful variation and added flavor.
