Prep the flank steak: add the sliced flank steak, baking soda, and water to a bowl and mix with hands until water is abosrbed. Add remaining ingredients and mix well. Set aside to marinate for at least 30 minutes at room temperature, or you can cover and refrigerate overnight. (This marinade is key to creating a velvety soft, tender meat for the stir fry!).
1 - 1 1/2 lb. flank steak*, 1/8 tsp. baking soda, 2 Tbsp. water, 2 tsp. cornstarch, 2 tsp. soy sauce, 2 tsp. Shaoxing wine, 1 tsp. sesame oil, 1 tsp. vegetable oil
Make the sauce: Whisk together all the sauce ingredients in a measuring cup. Set aside.
½ cup chicken broth, ½ cup soy sauce, 1 tbsp. sesame oil, 1 tbsp. rice vinegar, 2 tbsp. sugar, 1 tsp. minced garlic, 1 tsp. ginger, 1 Tbsp. cornstarch, chili flakes
Cook beef in batches: heat a wok over high heat. Once hot, add about 1 Tbsp. oil. Sear the beef for about 2 minutes each side. I like to cook it undisturbed to get a good sear before stirring. It will brown but still be a little rare/not cooked all the way, that’s perfect. Transfer the beef to another bowl or plate and cook remaining beef, adding more vegetable oil as necessary.
vegetable oil
Add veggies: working over medium-high heat, add a touch more oil to the wok then add in the garlic, ginger, veggies and green onions. Cook for a few minutes, or until the veggies are vibrant in color. If needed you can deglaze the pan with a little splash of shaoxing wine.
vegetable oil, 1 tsp. garlic, 1 tsp. ginger, 1 large head broccoli, 1 cup snap peas, 1 large carrot, 1 red bell pepper, 5 green onions
Add beef & sauce: add the beef and the sauce. Cook and stir occassionally for ~5-7 minutes, allowing the cornstarch from the sauce to thicken and coat the beef and veggies. If the sauce is too thin, you can add a little more cornstarch slurry (cornstarch + water) to the stir fry and allow to thicken. Taste and adjust any seasonings as desired.
Plate & serve: serve with rice or noodles, garnish with green onions, and enjoy!
