Served in an individual donabe clay pot, Nabeyaki Udon is a wintertime staple in Japan. In this recipe, thick chewy udon noodles are cooked in a flavorful dashi broth along with kamaboko fish cake, deep-fried tofu pouch, scallions, and an egg. Top it up with crispy shrimp tempura to make it extra fancy or keep it simple with what you have in the fridge.
