This beef and cauliflower stir-fry delivers tender slices of steak, crisp-tender vegetables, and a glossy savory sauce in every bite. Velveting the beef keeps it juicy, while garlic, ginger, soy sauce, and oyster sauce give the dish classic takeout-style flavor. Serve it with steamed rice for a fast and satisfying dinner.
Place the sliced flank steak in a medium bowl with the baking soda and water. Massage until the liquid is fully absorbed, then mix in the cornstarch, 2 tsp of the oil, and 2 tsp oyster sauce. Let the beef marinate for at least 30 minutes.
In a small bowl, whisk together the chicken stock, sugar, light soy sauce, dark soy sauce, sesame oil, white pepper, and the remaining oyster sauce until smooth. Bring a large pot of water to a boil, blanch the cauliflower florets for 30 to 60 seconds, then drain well and set aside.
Heat a wok or large skillet over high heat until very hot. Add 2 tbsp of oil, spread the beef into a single layer, and sear without moving for about 1 minute. Flip and cook just until browned and about 80% cooked through, then transfer the beef to a plate.
Reduce the heat to medium and add the remaining oil to the wok. Stir in the garlic and ginger for a few seconds until fragrant, then pour the Shaoxing wine around the edge of the wok. Add the blanched cauliflower and pour in the sauce.
Bring the sauce to a gentle simmer and stir to coat the cauliflower evenly. Let it cook for 1 to 2 minutes so the cauliflower absorbs the flavor. If you prefer a thicker sauce, simmer a little longer or add a small cornstarch slurry a little at a time.
Return the beef and any resting juices to the wok. Toss everything together over medium heat until the beef is fully cooked and the sauce lightly coats the cauliflower and meat. Serve hot with steamed rice.
For the best texture, do not skip the velveting step or overcook the beef during the first sear. Broccoli works well if you do not have cauliflower, and dry sherry can replace Shaoxing wine. Store leftovers in an airtight container in the refrigerator for up to 3 days and reheat quickly over medium heat.
