Onsen Egg and Beef Rice Bowl

Enjoy an easy, umami-rich Japanese rice bowl!

This miso beef and onion bowl topped with a “hot spring” egg is a delicious and quick meal that can be made in under 30 minutes. The rice bowl is full of flavor and is a great dish for lunch or dinner.

Onsen Tamago, meaning hot spring egg in Japanese, is a slowly cooked egg with a custardy egg-white and runny egg yolk. It is very similar to a poached egg, with the only differences being the cooking method and the egg white consistency. The egg is traditionally cooked in hot spring waters in Japan and served with an umami broth. The egg can be eaten by itself or served with other dishes like rice or noodles as it provides a creamy richness to the dish.

The runny yolk in an onsen egg is no different from that of a sunny side-up or a poached egg. Runny egg yolks are generally safe to eat, although high-risk individuals such as pregnant women and immune-deficient individuals should avoid them. Do not use any eggs that are cracked.
