Quick Facts

  • Yield: Serves 4
  • Prep Time: 15 minutes
  • Cook Time: 10 minutes
  • Total Time: 25 minutes

Ingredients

For the Main Dish:

  • 1 lb flank steak, thinly sliced against the grain
  • 2 tbsp vegetable oil (plus extra if needed)
  • 1 medium onion, thinly sliced
  • 1 green bell pepper, sliced into strips
  • 3 cloves garlic, minced
  • 1 tsp freshly ground black pepper (use more if you like it spicy)
  • 1/2 tsp kosher salt
  • 2 green onions, chopped (for garnish)

For the Sauce:

  • 3 tbsp soy sauce
  • 1 tbsp oyster sauce
  • 1 tsp cornstarch
  • 3 tbsp water
  • 1 tsp sugar

How I Make It

Step 1:

First up, slice the flank steak thinly—this makes for tender bites and faster cooking. Toss the beef with 1 tsp soy sauce and half the black pepper. Let it sit while you prep the veggies. Pro tip: slice against the grain to keep the beef tender.

Step 2:

Mix the sauce ingredients in a small bowl—soy sauce, oyster sauce, cornstarch, water, and sugar. Stir well until the cornstarch dissolves completely. This sauce will thicken beautifully in the pan.

Step 3:

Heat 2 tbsp oil in a large skillet or wok over medium-high heat until shimmering. Add the sliced beef in a single layer and sear quickly, about 1-2 minutes per side. Remove the beef and set aside to prevent overcooking.

Step 4:

In the same pan, add the onion, bell pepper, and garlic. Stir-fry for 3-4 minutes until the veggies are just tender but still crisp and colorful. Don’t overcook here—you want that crunch!

Step 5:

Return the beef to the pan, pour in the sauce and sprinkle the remaining black pepper. Stir everything together and cook for another 2 minutes until the sauce thickens and coats the beef and veggies nicely.

Step 6:

Finish by tossing in the chopped green onions for a fresh, vibrant pop of color and flavor. Serve immediately and get ready for those compliments!

Variations & Tips

  • Swap flank steak for sirloin or skirt steak if you prefer.
  • Add snap peas or baby corn for extra crunch and color.
  • If you like heat, throw in a sliced chili or a pinch of red pepper flakes.
  • For a gluten-free version, use tamari instead of soy sauce.
  • Marinate the beef for 30 minutes for even deeper flavor.
  • Use freshly cracked black pepper for the best punch—don’t skimp here!

How I Like to Serve It

I love spooning this Black Pepper Beef Stir-Fry over a bed of steamed jasmine rice or fluffy quinoa to soak up the sauce. It also goes great alongside simple garlic fried rice or even wrapped in warm lettuce leaves for a lighter option. Perfect for a busy weeknight or whenever you need that peppery kick.

Notes

  • Store leftovers in an airtight container in the fridge for up to 3 days; reheat gently to avoid toughening the beef.
  • If the sauce gets too thick after refrigeration, loosen with a splash of water or broth while reheating.

Closing: This recipe is proof that quick, bold flavors don’t require a fuss—Black Pepper Beef Stir-Fry always delivers that perfect punch of tasty satisfaction!
