I kept getting videos about hambagu steak and was extremely curious about it! It did not disappoint! The fries almost stole the show though ;)

Steps

1 hour

1

Mix ground beef, breadcrumbs, caramelized onion, egg, Worcestershire sauce, herbs, salt, and pepper.
2

Shape into patties and sear both sides in a pan until browned.
3

Combine soy sauce, ketchup, and Worcestershire sauce in the pan; simmer patties in sauce.
4

Boil potatoes until soft, mash with butter, milk, and herbs.
5

Coat cut and ice bathed fries in cornstarch and flour, fry once at 160°C, cool, then fry again at 190°C until crispy and light golden color.
6

Toss fries with melted butter, garlic powder, and dried parsley.
7

Serve hambagu steak over mashed potatoes, pour sauce, and sprinkle with herbs. Add fries on the side.

Tips

For extra flavor, caramelize the onions slowly over low heat until golden brown. Double-frying the fries ensures they are extra crispy.

Student finally upgraded from a dorm hot plate to a real kitchen. I grew up on Indian and traditional Bengali food, and now I try dishes way above my skill level just because I can. No matter how small my paycheck is, I’ll always spend it on good ingredients. Cooking is my love language, and my cat, Alu, fully supports this lifestyle.
