Beef, Broccoli & Mushroom Stir-Fry with Garlic Ginger Sauce
A quick and tasty weeknight meal that balances savory beef, bright broccoli, and umami mushrooms.
Ingredients
For the Beef Marinade
- 1 pound flank or skirt steak, sliced thin against the grain
- 1 tablespoon soy sauce
- 1 tablespoon vegetable or peanut oil
- 1 tablespoon cornstarch
- ½ teaspoon baking soda (optional, for extra tenderness)
- Salt and black pepper, to taste
For the Sauce
- ½ cup chicken or beef broth
- 2 tablespoons soy sauce
- 2 teaspoons brown sugar (or white sugar)
- 1 tablespoon cornstarch
- 1 teaspoon dark soy sauce (optional, for rich color)
For the Stir-Fry
- 1 large head broccoli, cut into bite-sized florets
- 8 ounces mushrooms (cremini or shiitake), sliced
- 3 cloves garlic, minced
- 2 teaspoons fresh ginger, grated or minced
- 1 tablespoon vegetable or peanut oil
- ¼ cup water (for steaming broccoli)
Instructions
Marinate the Beef
- Slice the steak thinly against the grain (about ¼ inch thick).
- In a bowl, combine soy sauce, oil, cornstarch, baking soda, salt, and pepper.
- Mix by hand until evenly coated. Let marinate for 10–15 minutes while you prepare the sauce and vegetables.
Make the Sauce
- Whisk together broth, soy sauces, sugar, and cornstarch in a bowl until smooth.
- Set aside.
Steam the Broccoli
- Add ¼ cup water to a large skillet or wok and bring to a simmer over medium-high heat.
- Add the broccoli florets, cover, and steam for 1–2 minutes, until bright green and slightly tender.
- Remove from the pan and set aside. Wipe away any remaining water.
Cook the Mushrooms
- Add ½ tablespoon oil to the same pan.
- Add the mushrooms and sauté for 3–4 minutes, stirring occasionally, until golden brown and lightly caramelized.
- Transfer to a bowl and set aside.
Sear the Beef
- Increase heat to high and add the remaining ½ tablespoon oil.
- Spread the marinated beef in a single layer and cook without stirring for about 30 seconds until browned on one side.
- Flip and cook another 30–45 seconds, or until just cooked through.
Add Aromatics and Combine
- Lower the heat to medium-high.
- Add the garlic and ginger; stir quickly for 20–30 seconds, releasing their fragrance.
- Return the broccoli and mushrooms to the pan.
- Give the sauce another quick stir (to dissolve any settled cornstarch), then pour it into the pan.
- Cook and toss everything together for 1–2 minutes, until the sauce thickens and coats the ingredients evenly.
Serve
- Transfer to a serving dish and enjoy immediately with steamed rice or noodles.
- Garnish with sesame seeds or sliced scallions if desired.
Notes
Slice the beef thin against the grain for tenderness. Pat the beef dry if it sticks; high heat gives a quick sear. Steam broccoli briefly so it stays bright and crisp. Stir sauce before adding if cornstarch has settled.
