This quick and savory pressure cooker flank steak dish brings together Chinese flavors like oyster sauce, soy, garlic, and Shaoxing wine for a restaurant-worthy meal in minutes. Veggies stay crisp and meat turns melt-in-your-mouth tender—all with minimal effort. Perfect over rice and ready for busy nights.
In a bowl, mix your flank steak with 1 tablespoon oyster sauce, soy sauce, Shaoxing wine, cornstarch, and just a pinch of salt. Let that soak up flavor at least 15 minutes.
Heat 1 tablespoon vegetable oil in a wok or skillet. Get it hot, then sear your beef slices until browned but not cooked through—about 2-3 minutes. Take them out and set aside.
Add the remaining oil then toss in garlic and onions. Stir-fry for about a minute until aromatic.
Stir-fry the broccoli and red bell pepper for 2 to 3 minutes to preserve their crisp-tender texture.
Return the beef to the pan and pour in the remaining oyster sauce. Stir everything well to coat evenly.
Drizzle the sesame oil on top, adjust seasoning with salt and pepper, and stir-fry for 1 final minute.
Serve hot over steamed rice and enjoy!
Notes
You can marinate the beef longer or overnight for deeper flavor. Frozen broccoli can be subbed in to save prep time.
