Black Pepper Beef, Mushroom & Green Bean Stir-Fry is a bold, savory one-pan meal made with tender beef, crisp green beans, and umami-packed mushrooms tossed in a garlicky, peppery sauce. It’s a quick, hearty dish perfect for weeknights.

Ingredients

  • 1 lb flank steak or sirloin, thinly sliced against the grain
  • 2 cups fresh green beans, trimmed
  • 1 1/2 cups mushrooms (cremini, button, or shiitake), sliced
  • 3 cloves garlic, minced
  • 1 tsp fresh ginger, grated (optional)
  • 3 tbsp soy sauce (low-sodium if preferred)
  • 2 tbsp oyster sauce
  • 1 tbsp cornstarch
  • 1/2 tsp freshly ground black pepper (more to taste)
  • 1 tsp sugar
  • 2 tbsp vegetable oil or sesame oil
  • 1/4 cup water or beef broth
  • Optional: red chili flakes or sliced green onions for garnish

Instructions

  1. In a bowl, toss sliced beef with 1 tbsp soy sauce, cornstarch, and a pinch of black pepper. Let marinate for 10 minutes.
  2. Heat 1 tbsp oil in a large skillet or wok over high heat. Stir-fry beef in batches until browned and just cooked through. Remove and set aside.
  3. Add remaining oil if needed, then sauté green beans for 3–4 minutes until crisp-tender.
  4. Add mushrooms and cook until golden. Stir in garlic and ginger and cook for 30 seconds until fragrant.
  5. Return beef to the pan. Add remaining soy sauce, oyster sauce, sugar, water or broth, and remaining black pepper. Stir to combine.
  6. Let the sauce bubble and thicken slightly, about 1–2 minutes. Drizzle with sesame oil if desired.
  7. Garnish with red chili flakes or green onions before serving. Serve hot over rice or noodles.

Notes

  • Add bell peppers or snap peas for extra color and crunch.
  • Use low-sodium soy sauce and omit oyster sauce for a lower-sodium option.
  • Swap beef with chicken, pork, or tofu as desired.
  • To make gluten-free, use tamari and a gluten-free oyster sauce substitute.
