1 cup thinly sliced red cabbage, plus more for serving
1 medium carrot, peeled and grated
okonomiyaki sauce (see notes), Kewpie mayonnaise, bonito flakes, furikake and thinly sliced green onions (for serving)
Instructions
Bring a medium pot of water to a boil. Cook udon noodles until al dente according to package directions. Rinse with cold water, drain well and set aside.
Preheat oven to 350 degrees.
In a medium bowl, combine the eggs, chicken broth, flour and salt; whisk until smooth and set aside.
Heat butter in a 9" oven-safe fry pan over medium-high heat. Add cabbage and carrot and cook, stirring occasionally, until just tender, about 2 minutes. Add prepared udon and stir to combine.
Add egg mixture to fry pan and cook, without stirring, for 6 minutes.
Bake for 7-9 minutes or until the filling is set and the tip of a knife inserted into the center comes out clean.
Remove from the oven and invert okonomiyaki onto a large plate. Drizzle with okonomiyaki sauce and Kewpie mayonnaise. Top with bonito flakes, furikake, green onions and additional red cabbage. Serve immediately.
