Japanese Okonomiyaki Fries bring all those craveable umami-packed toppings of Japan's favorite savory pancake to a platter of golden, crispy fries. This recipe is always a hit at my gatherings—it sounds extravagant but comes together with simple ingredients and sparks real excitement when served hot from the oven with its aromatic sauces and playful toppings.

When I brought these out for movie night, no one could stop snacking—they disappeared faster than any pizza. Now, friends request them whenever we hang out.

Ingredients

  • Russet potatoes: choose ones that feel heavy for their size and have smooth skin for the crispiest fries
  • Vegetable oil: neutral flavor and high heat tolerance make it perfect for roasting fries
  • Salt: highlights the natural flavor of potatoes
  • Ketchup: forms the base of the sweet& tangy okonomiyaki sauce
  • Worcestershire sauce: layers in savory depth with its complex umami hit
  • Oyster sauce: adds rich, savory sweetness
  • Soy sauce: salty depth and a hint of color
  • Sugar: balances acidity and salt for classic Japanese street snack taste
  • Japanese mayonnaise, preferably Kewpie: creamy and slightly sweet for the signature drizzle
  • Shredded nori: adds oceanic umami and a subtle crunch; look for bright, crisp sheets
  • Green onions: choose firm, fresh stalks for a zesty garnish
  • Pickled ginger: vivid color and tart bite that cuts through richness
  • Bonito flakes: smoky umami touch, waving beautifully atop hot fries
  • Toasted sesame seeds: nutty crunch and aromatic finish

Instructions

Prepare the Fries:
Peel and cut russet potatoes into classic fry shapes for even cooking. Toss thoroughly with vegetable oil and salt so every fry is coated. Spread fries in a single layer on a parchment-lined baking sheet to maximize crispiness.
Roast to Perfection:
Bake the fries in a hot oven at 220 degrees Celsius or 425 degrees Fahrenheit. Flip halfway through so both sides crisp up. Bake until every piece is golden and crunchy outside but fluffy inside.
Mix the Signature Sauce:
While fries are baking, combine ketchup, Worcestershire sauce, oyster sauce, soy sauce, and sugar in a small bowl. Stir vigorously until the mixture is completely smooth—taste for that tangy, savory-sweet Japanese street food flavor.
Get the Toppings Ready:
Finely slice green onions, chop pickled ginger, and have shredded nori, bonito flakes, and sesame seeds on hand so you can assemble quickly while the fries are hot.
Assemble the Loaded Fries:
As soon as fries come out of the oven, pile them onto a large platter. Drizzle generously with your homemade okonomiyaki sauce and zigzag with Japanese mayonnaise. Sprinkle over the toppings: a shower of nori, a scatter of green onions and pickled ginger, fluttering bonito flakes, and a final dusting of sesame seeds.
Serve Immediately:
Bring to the table while everything is piping hot and crispy—fries will soak up just the right amount of sauce without getting soggy.

Something about the ribbons of nori and shavings of bonito always makes me smile. The first time my partner tried these, he said it tasted like eating at a tiny izakaya in Tokyo, but even more fun because everyone was digging in with their fingers.

Storage Tips

Store any leftovers (though there rarely are) in an airtight container and reheat in a hot oven or air fryer to restore crispiness. Avoid microwaving as it can make fries soggy. Store toppings and sauce separately if preparing ahead.

Ingredient Substitutions

For vegan fries use egg-free mayonnaise and vegetarian oyster sauce. Skip bonito flakes for a fully plant-based platter. You can also use frozen fries for extra convenience without sacrificing too much on texture.

Serving Suggestions

Great as a shared appetizer or snack with friends. Pair with cold Japanese beers or a glass of chilled sake. A little extra pickled ginger on the side brightens the experience. If you love heat, add a squirt of Sriracha or a sprinkle of shichimi togarashi.

Cultural Context

Okonomiyaki is a beloved comfort dish from Osaka and Hiroshima, made from cabbage pancakes griddled to perfection then painted with sweet-savory sauce and dripping mayonnaise. This recipe gives a Western spin while keeping those classic flavors that capture the spirit of Japanese street food.

Seasonal Adaptations

Fresh spring onions and sweet new potatoes in spring. Sweet potato fries with shichimi in autumn. Top with quick-pickled radish in summer.
