Instructions

Marinate the Steak: In a medium bowl, toss the thinly sliced steak with the low-sodium soy sauce and cornstarch until evenly coated. Let it rest for 10–15 minutes to absorb the flavors.
Cook the Steak: Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat. Add the marinated steak in a single layer and cook for 2–3 minutes on each side until browned and just cooked through. Remove the steak from the pan and set aside.
Sauté Vegetables: Add the remaining tablespoon of vegetable oil to the skillet. Toss in the sliced red and green bell peppers and yellow onion. Sauté for 4–5 minutes until the vegetables are tender-crisp.
Add Aromatics: Stir in the minced garlic and freshly grated ginger into the vegetables. Cook for an additional 1 minute until fragrant.
Combine and Sauce: Return the cooked beef to the pan with the vegetables. Add the oyster sauce if using, black pepper, and beef broth or water. Stir well to combine and cook for 1–2 more minutes until the sauce thickens slightly and the beef is heated through.
Finish and Garnish: Drizzle with sesame oil if desired. Garnish with sliced green onions and sesame seeds before serving to add extra flavor and texture.

Notes

For a spicier version, add crushed red pepper flakes or a splash of chili garlic sauce during the cooking process.
Serve over steamed rice, noodles, or use cauliflower rice for a low-carb option.
Using low-sodium soy sauce helps control the salt content in this dish.
Marinating the beef with cornstarch helps achieve a tender texture and a slight thickening effect in the sauce.
