About this dish
Broad, thin sheets of sirloin cut across the grain give this neobiani a tender bite, and the beef stays in whole slices instead of being minced into patties.

Grated onion and sugar in the soy marinade brown fast and scorch before the beef does, so the slices are laid in one layer without the leftover marinade.
Ingredients
Instructions
- 1
Trim tough connective tissue from 500 g sirloin.
Slice across the grain, 3 to 5 mm thick and about 5 cm wide, then cut long pieces to roughly 7 cm. Separate any slices that are folded together.
- 2
Grate 80 g onion and finely chop 30 g green onion.
Mix with 3 tablespoons soy sauce, 1 tablespoon sugar, 1 tablespoon minced garlic and 1/2 teaspoon black pepper. Add 2 teaspoons of the 1 tablespoon sesame oil; reserve the remaining teaspoon for the pan.
- 3
Coat both sides of the beef slices with the marinade.
Cover and refrigerate for 30 minutes, keeping the slices separate rather than kneading or shaping the meat.
- 4
Heat a frying pan over medium heat.
Use the reserved teaspoon of sesame oil to lightly coat the pan across the batches. Lift the beef from the marinade, let excess drip off and lay the slices in a single layer. Keep the used raw-meat marinade off the cooked beef.
- 5
Check the first side after about 2 minutes and turn when browned.
Cook the second side, using a thin-probe thermometer inserted from the side into the thickest slice to check that the center reaches at least 63°C (145°F). Adjust the cooking time to the thickness and pan heat. Lower the heat if the marinade burns.
- 6
Transfer cooked beef to a clean plate and rest for at least 3 minutes before serving.
Cook the remaining slices in batches, wiping away burnt marinade from the pan between batches.
