📘 What Is Okonomiyaki

Okonomiyaki (お好み焼き) is a Japanese savory pancake made of flour, cabbage, and other ingredients. It is pan-fried and then topped with a sauce made of Worcestershire sauce, mayonnaise, seaweed flakes, and bonito flakes.

This recipe swaps the pancakes for fries and makes use of the same toppings for a flavor similar to okonomiyaki!

If you are looking for a recipe for regular Vegan Okonomiyaki, I have got you covered as well!

Ingredients like potatoes, green onions, ketchup, worcestershire sauce, coconut sugar, mayo.

🥣 How to Make It

French Fries

It starts with the fries. I recommend going with a type of potato with a high-starch content and low moisture, like Russet potatoes, for the best texture and flavor.

Peel the potatoes and cut them into 1/2-inch thick matchsticks. Next, soak them in cold water for about 40 minutes. This step will help remove some of the excess starch and allow the fries to get crispier during frying.

Then, for cooking the fries, I am sharing two options: deep-frying or air-frying.


This version yields crispier and better fries overall. Start by heating a pot of oil to 275°F (135°C). Once hot, fry the potatoes for about 5 minutes. Next, drain the potatoes and bring the heat of the oil to 400°F (200°C). Fry the potatoes a second time for another 5-7 minutes or until golden brown.


If you prefer a lower-fat, healthier option, you can air-fry the potatoes for about 10 minutes or until golden brown.

Now that the fries are done. Let’s talk about the toppings, which are the icing on the cake!

  • Okonomiyaki sauce: Prepared from ketchup, vegan Worcestershire sauce, soy sauce, and sugar, this sauce is sweet and salty with a subtle tang.
  • Vegan mayo: Use store-bought or homemade.
  • Green onions: Raw or sautéed. Personally, I sautéed the green onions for 1 minute in a teaspoon of oil.
  • Aonori: You can use regular aonori, or shiso furikake for a more floral flavor.
  • Vegan meat floss and fried onions: Homemade vegan meat floss for texture and fried shallots or onions for extra crispiness.

To serve, arrange the French fries on a plate, then drizzle with the okonomiyaki sauce vegan mayo, and top with the remaining toppings!

📔 Tips

  • Do not add too much salt to the fries, as the toppings are already quite salty.
  • If you do not have a thermometer or a deep-fryer, you can deep-fry the fries a single time in a deep saucepan.
  • These French fries are best served immediately for the best texture.

I hope you are going to love this dish! While it is definitely not traditional, it’s a fun and delicious take on the regular okonomiyaki! It has the perfect balance of sweet and salty, and it’s loaded with different textures!
