Okonomiyaki Flour Mix: Make Your Own at Home

Okonomiyaki flour mix is a seasoned dry blend for making okonomiyaki, the savory Japanese cabbage pancake cooked on a griddle and finished with sauces and toppings. This easy homemade version uses pantry ingredients, with a little baking powder for lift; mix it with egg and water when you are ready to cook.

Ingredients

1 cup (125 g) all-purpose flour
2 tablespoons (16 g) potato starch or cornstarch
1 teaspoon (4 g) baking powder
1 teaspoon (5 g) fine salt
1 teaspoon (2 g) granulated sugar
1 teaspoon (2 g) instant dashi powder, optional but recommended
½ teaspoon (1 g) ground white pepper, optional
4 large eggs (about 200 g without shells), for the batter
½ cup (120 ml) cold water, plus 1 tablespoon (15 ml) if needed
4 cups (280 g) finely shredded green cabbage
4 scallions (about 40 g), thinly sliced
2 tablespoons (30 ml) neutral cooking oil, for the pan
¼ cup (60 ml) okonomiyaki sauce, for serving
2 tablespoons (30 g) Japanese mayonnaise, for serving
1 tablespoon (3 g) aonori (dried green seaweed), optional
2 tablespoons (4 g) bonito flakes, optional

Instructions

Combine the dry mix. Whisk the flour, potato starch, baking powder, salt, sugar, dashi powder, and white pepper in a bowl until evenly distributed. This makes about 1½ cups (180 g) of mix, enough for four portions. If making the mix ahead, transfer it to an airtight container and label it.
Make the batter. In a large bowl, beat the eggs with ½ cup (120 ml) cold water. Add the dry mix and stir just until no large dry patches remain. A few small lumps are fine; overmixing can make the pancakes dense. Fold in the cabbage and scallions so the vegetables are coated. The mixture should be thick and full of cabbage, not pourable. Add up to 1 tablespoon (15 ml) water only if it is too dry to hold together.
Heat the pan. Warm a large nonstick skillet or flat griddle over medium heat and brush with a little of the oil. Divide the mixture into four portions. Cook two at a time if necessary to leave room for turning; keep the remaining batter refrigerated while the first batch cooks.
Cook the pancakes. Scoop each portion into the pan and shape it into a round about 6 inches (15 cm) wide and ¾ inch (2 cm) thick. Cook for 4–5 minutes, until the underside is golden and the edges look set. Slide a wide spatula underneath and turn carefully. Cook the second side for another 4–5 minutes, pressing gently once so the center cooks evenly. Lower the heat if the outside browns too fast.
Check that they are done. The center should be hot and set, with no wet batter. Because these pancakes contain egg, use a food thermometer in the center of the thickest pancake: the USDA FSIS safe minimum temperature for egg dishes is 160°F (71°C). If needed, cover the pan and cook over low heat for another 1–2 minutes, then check again. Transfer the cooked pancakes to a plate and repeat with the remaining oil and batter.
Finish and serve. Drizzle each pancake with okonomiyaki sauce and Japanese mayonnaise. Sprinkle with aonori and bonito flakes, if using, and serve hot.

Tips

Choose the starch you have. Potato starch is traditional in some Japanese mixes and gives a slightly springier texture. Cornstarch works well too, though the result may be a little less tender.
Dashi is optional. Instant dashi adds a savory, seaweed-and-fish depth. For a vegetarian mix, omit it or use a labeled vegetarian kombu or shiitake dashi; check the package because many dashi powders contain bonito.
Keep the cabbage fine and dry. Shred it into thin pieces so the pancake binds and cooks through. If rinsed, dry the cabbage well; excess water can make the batter loose.
Mix only when ready to cook. Baking powder starts working once it meets liquid, and cabbage releases moisture as it sits. Store the dry mix separately and combine it with the wet ingredients shortly before cooking.

Serving Suggestions

Serve okonomiyaki as a main dish for lunch or dinner, with miso soup, steamed rice, or a simple cucumber salad alongside. Okonomiyaki sauce is a sweet-savory Japanese condiment; if it is hard to find, use a blend of 2 tablespoons (30 ml) Worcestershire sauce and 1 tablespoon (15 ml) ketchup per pancake. The flavor will be tangier and less rounded than the original. Japanese mayonnaise is richer and often more savory than standard mayonnaise, but regular mayonnaise is a practical substitute. Add sauce and mayonnaise just before eating so the crisp surface does not soften too much.

Variations

Okonomiyaki varies by region and household. For a simple vegetarian pancake, leave off bonito flakes and choose vegetarian dashi. For a seafood version, fold in about 4 ounces (115 g) cooked shrimp, chopped into small pieces, or use cooked squid; keep raw seafood chilled until cooking and make sure the finished center reaches 145°F (63°C), the USDA FSIS safe minimum for fish and seafood. For a heartier topping, cook thin slices of pork belly on the first side of the pancake, then flip so the pork cooks against the pan; check that pork reaches 145°F (63°C) with a 3-minute rest. This differs from ground pork, which must reach 160°F (71°C). You can also add a small handful of tenkasu (crispy tempura bits) to the batter for extra crunch, though they soften as the pancake sits.

Storage and Reheating

For best quality, store the dry flour mix in an airtight container in a cool, dry cupboard for up to 2 months; discard it if it smells stale or shows signs of moisture. Cooked pancakes should be refrigerated within 2 hours in a covered container and used within 3–4 days. Reheat in a skillet over medium-low heat until hot throughout, or microwave in short bursts; leftovers must reach 165°F (74°C) when reheated. Freeze cooked, cooled pancakes in a sealed freezer-safe bag for up to 2 months for best quality, then thaw in the refrigerator and reheat to 165°F (74°C). Do not store mixed batter for later; cook it promptly.

Frequently Asked Questions

Can I make okonomiyaki flour mix without dashi?
Yes. Leave out the dashi powder and use the mix as written. The pancakes will be less savory, so you can add a little extra scallion or use a vegetarian kombu-based dashi if you want more depth.

Is this the same as store-bought okonomiyaki flour?
It is a useful homemade substitute, but packaged mixes can contain additional seasonings, leaveners, or dried ingredients. This blend keeps the ingredient list simple and gives you control over the salt and dashi.

Can I prepare the dry mix in advance?
Yes. Whisk it together and keep it airtight in a cool, dry place for up to 2 months. Keep the wet ingredients and cabbage separate until you are ready to cook, and write the date on the container.

Why is my pancake falling apart?
The cabbage may be cut too coarsely, the mixture may be too dry, or you may be turning it before the bottom has set. Shred the cabbage finely, add water a teaspoon at a time if needed, and wait until the edges look firm before flipping with a wide spatula.

Can I make this gluten-free?
Use a certified gluten-free all-purpose flour blend in place of the wheat flour, and check that the dashi and toppings are also gluten-free. Blends vary, so the batter may need a small splash of water to reach a thick, scoopable consistency.

Can I use the mix for other dishes?
It works best for cabbage-based okonomiyaki. You can use it as a savory pancake base with other finely chopped vegetables, but avoid treating it as a one-to-one substitute for plain flour in baking because it contains salt, starch, and baking powder.
