Niku Udon with Onsen Tamago is a hot Udon noodle soup topped with sweet and salty braised beef and Onsen Tamago (silky semi-cooked egg). The savory beef adds richness and depth to the rather simple Udon noodle soup, while the thick Onsen Tamago coats both the noodles and beef, bringing the flavors together well, similar to the experience of dipping Sukiyaki beef with eggs. This is a delicious dish to enjoy at restaurants and also a great meal to cook at home.
