Trim any large pieces of fat from the beef and slice thinly across the grain into 1/8–1/4-inch slices. Pat slices dry with paper towels to help the marinade cling.

2. Make the marinade

In a bowl, whisk together 1/2 cup low-sodium soy sauce, 2 tbsp brown sugar, 1 tbsp rice vinegar, 1 tsp sesame oil, grated ginger, minced garlic, and 1/2 tsp black pepper until sugar dissolves.

3. Marinate

Place the sliced beef in a shallow dish or zip-top bag and pour the marinade over. Mix to coat all pieces, pressing them flat so marinade covers evenly. Refrigerate for 30 minutes to 2 hours (30 minutes for quick flavor, up to 2 hours for deeper flavor).

4. Prepare cornstarch

Shortly before cooking, toss the marinated meat with 1 tbsp cornstarch so each piece gets a light, even dusting. This helps create a slightly glossy exterior and helps the glaze cling.

5. Cook the meat

Heat a large skillet or heavy-bottomed pan over medium-high heat until very hot. Add 1 tbsp neutral oil and swirl. Add the meat in a single layer (work in batches if necessary to avoid overcrowding). Sear without moving for 30–45 seconds, then stir and continue cooking 1–2 minutes until slices are browned at edges and just cooked through. Remove meat to a plate and set aside. Leave any fond (browned bits) in the pan.

6. Deglaze and build glaze

With the pan still over medium-high heat, add hoisin sauce, 2 tbsp honey, 1/2 tsp dark soy, and 1 tsp mirin (if using) to the pan. Stir to combine with the browned bits, scraping the bottom of the pan with a wooden spoon to lift flavor. Let the mixture bubble gently for 30–45 seconds.

7. Thicken glaze

In a small cup, whisk 2 tbsp water with the reserved 1 tbsp cornstarch (if any cornstarch remained; otherwise make a fresh 1 tsp cornstarch slurry) until smooth. Pour the slurry into the simmering sauce and stir constantly for 20–30 seconds until the glaze thickens to a glossy, syrupy consistency. Taste and add up to 1/4 tsp salt if needed.

8. Finish the meat with glaze

Return the cooked meat and any accumulated juices to the pan. Toss quickly and continuously over medium heat until every slice is evenly coated and heated through, about 30–60 seconds. Avoid overcooking; meat should remain tender and juicy.

9. Garnish and serve

Transfer glazed meat to a serving plate. Sprinkle with thinly sliced green onions and 1 tsp toasted sesame seeds. Serve immediately over steamed rice, noodles, or as a protein topping for salads or bowls.
