Gyūdon with Onsen Tamago

Gyudon is one of Japan's great everyday meals — thinly sliced beef and onion cooked down in a glossy, savory sweet broth, spooned over rice in a donburi bowl. It belongs to a category of Japanese cooking called don mono, a family of dishes that are quick to make, deeply satisfying. This recipe comes together in under 30 minutes, and with a homemade onsen tamago on top, it might just become your new weeknight staple.
