Sweet Potato and Brussels Sprout Okonomiyaki

This vibrant sweet potato and brussels sprout okonomiyaki offers a nutritious, high-protein twist on the classic Japanese savoury pancake. By substituting the traditional cabbage base with earthy sweet potato and shredded sprouts, the dish gains a wonderful textural crunch and a natural sweetness that caramelises beautifully in the frying pan. The result is a satisfying, golden pancake that serves as a brilliant vehicle for bold umami toppings.

Ideal for a quick midweek dinner or a filling weekend lunch, this recipe is packed with fibre and vitamins while remaining incredibly simple to prepare. Using seasonal vegetables makes this an affordable way to enjoy authentic Japanese flavours at home. Serve your okonomiyaki hot from the pan, finished with a decorative lattice of creamy mayonnaise and a sprinkle of savoury furikake for a truly professional finish.

Ingredients for Sweet Potato and Brussels Sprout Okonomiyaki

  • 90g brussels sprouts, ends trimmed, very thinly sliced (about 150g )

  • 1 medium sweet potato, julienned (about 650g )

  • 1 spring onion, thinly sliced

  • 1 large egg, beaten to blend

  • Kosher salt

  • 80ml plain flour

  • 90ml vegetable oil, divided

  • Sriracha, Kewpie mayonnaise, bonito flakes, and furikake (for serving)

How to make Sweet Potato and Brussels Sprout Okonomiyaki

Combine brussels sprouts, sweet potato, spring onion, and egg in a large bowl; season with salt. Mix with your hands until vegetables are evenly coated. Sprinkle flour over vegetables and toss to combine (mixture shouldn’t be gummy, but a handful should clump together).

Heat 1 tablespoon oil in a large nonstick skillet over medium-high. Add half of vegetable mixture; press into a thin even layer across bottom of skillet. Cook until pancake begins to set, about 1 minute. Drizzle 1 tablespoon oil around edge and shake to ensure pancake can slide around; cook until golden brown underneath, about 2 minutes longer. Slide pancake onto a baking sheet or the underside of a flat pot lid, then invert pancake back into skillet. Drizzle 1 tablespoon oil around edge of pancake and cook until second side is golden brown, about 2 minutes. Repeat with remaining vegetable mixture and 45ml oil to make another pancake. Serve topped with Sriracha, mayonnaise, bonito flakes, and furikake.
