This incredibly delicious Yoshinoya Beef Bowl (Gyudon) is a recipe keeper, with juicy thinly sliced beef and tender sweet onion served over a bowl of steaming rice.
Cut the thinly sliced beef into 3-inch/7.5cm long strips. Separate the beef so that it does not clump when cooked.
Add dashi, sugar, sake, mirin, and soy sauce into a large frying pan. Stir until well combined. Put the frying pan over medium-high heat. Cover with a lid and bring the mixture to boil. (If you don't cover, the sauce will evaporate)
Add thinly sliced onion into the boiling sauce. Cover the frying pan with a lid and cook until the onion is tender for about 3-4 minutes.
Once the onion is tender, add the beef. Stir and make sure the beef is submerged into the sauce. Cover the frying pan with a lid and cook for 4-5 minutes.
Turn of the heat. Spoon the beef over rice.
Serve with onsen tamago and scallions, or other toppings if desired.
Notes
Sake helps to tenderize the meat and remove the meat odor. You can omit the sake if you don't have one.
