Ingredients
beef sirloin or ribeye
300g, thinly sliced against the grain
green bell peppers
2 medium, seeded and sliced
vegetable oil
1 tablespoon
garlic
2 cloves, minced
fresh ginger
1 teaspoon, grated
soy sauce
1 tablespoon
oyster sauce
1 tablespoon
freshly ground black pepper
1 teaspoon, or more to taste
cornstarch
1/2 teaspoon
water
1 tablespoon
salt
to taste
Instructions
1
Prep the beef
Slice the beef into thin strips, about 1/4 inch thick. Cut against the grain for maximum tenderness. Mix the cornstarch with the water until smooth, then toss the beef strips in the mixture. This creates a light coating that helps the sauce cling.
2
Slice the vegetables
Wash the green bell peppers and cut them into bite-sized strips. Remove the seeds and white pith for a milder flavor. Have your minced garlic and grated ginger ready nearby.
3
Sear the beef
Heat oil in a wok or large skillet over high heat until shimmering. Add the beef strips in a single layer and let them sear for 30 seconds without stirring. Flip and cook another 30 seconds until browned but still slightly pink inside. Remove and set aside.
4
Build the sauce
In the same wok, add a splash more oil if needed. Sauté the garlic and ginger for 15 seconds until fragrant. Add the soy sauce, oyster sauce, and black pepper. Stir everything together.
5
Combine and serve
Return the beef to the wok along with any juices. Add the green pepper strips and toss everything together over high heat for 1-2 minutes until the peppers are crisp-tender but still bright. Season with salt to taste and serve immediately over steamed rice.
