- 1 tablespoon soy sauce: Adds depth and umami flavor; consider using low-sodium soy sauce for a healthier option.
- 1 tablespoon cornstarch: Helps with marinating the beef, ensuring it stays juicy.

- 1 teaspoon sesame oil: Imparts a nutty flavor that enhances the dish.
- 1 cup broccoli florets: Provides essential nutrients and a nice crunch; fresh or frozen works!

- 1 medium red bell pepper: Adds color and sweetness; you could also use yellow or green peppers.
- 2 tablespoons low-sodium soy sauce: For the sauce, making it flavorful but light on salt.

- 1 tablespoon white miso paste: Introduces umami depth; it’s a great way to enhance flavor.
- 1 tablespoon oyster sauce: Gives a glossy finish and a hint of sweetness; can be replaced with soy sauce if necessary.
- 1 tablespoon Shaoxing wine or dry sherry: Offers acidity and balance to the dish; replace with rice vinegar if needed.
- ½ cup beef stock: Use homemade or store-bought for a rich base; chicken stock can be an alternative.
- 2 teaspoons brown sugar: Balances the flavors; feel free to reduce the amount if you prefer less sweetness.
- 2 teaspoons freshly coarsely ground black pepper: Key to achieving that signature black pepper flavor.
- 2 teaspoons freshly minced garlic: A flavor powerhouse; fresh garlic makes a noticeable difference.
- 1 tablespoon cornstarch: Helps thicken the sauce for an enticing coating.

How to Make Panda Express Black Pepper Sirloin Steak
- Marinate the Beef: In a medium bowl, combine 1 pound of Angus sirloin steak cubes with 1 tablespoon of soy sauce, 1 tablespoon of cornstarch, ½ teaspoon of baking soda, and 1 teaspoon of sesame oil. Toss everything well to coat the beef. Cover and refrigerate for 15 to 30 minutes. This tenderizes the beef while enhancing its flavor.
- Make the Sauce: In a small bowl, whisk together 2 tablespoons of low-sodium soy sauce, 1 tablespoon of tomato paste, 1 tablespoon of white miso paste, 1 tablespoon of oyster sauce, 1 tablespoon of Shaoxing wine (or dry sherry), ½ cup of beef stock, 2 teaspoons of brown sugar, 2 teaspoons of freshly coarsely ground black pepper, 2 teaspoons of freshly minced garlic, and 1 tablespoon of cornstarch. Make sure the cornstarch and miso dissolve completely, then set it aside.
- Sear the Beef: Heat a wok or large skillet over high heat until very hot. Add 2 tablespoons of vegetable oil. Add the marinated beef in a single layer—don’t stir it just yet. Let it sear undisturbed for about 2 minutes until browned on the bottom. Then, flip it to sear the other side for another 1 to 2 minutes. It should be browned outside but not fully cooked through. Transfer it to a plate and set aside.
- Stir-Fry the Vegetables: In the same wok, add the remaining 1 tablespoon of oil. Toss in the yellow onion and sliced mushrooms. Stir-fry over high heat for about 2 minutes until softened. Next, add the broccoli florets and red bell pepper, stirring for an additional 1 to 2 minutes until they are crisp-tender yet still vibrant.
- Combine and Finish: Return the beef to the wok with the vegetables. Give the sauce a quick re-whisk and pour it over the stir-fried ingredients. Toss everything together and stir-fry over high heat for about 1 to 2 minutes. You’ll know it’s ready when the sauce thickens and coats everything evenly.
- Serve: Transfer the entire dish to a serving platter and enjoy it hot with a side of steamed white or brown rice.
Storing & Reheating
To store leftovers, let the dish cool to room temperature before transferring it to an airtight container. It can be stored in the refrigerator for up to 3 days. If you want to keep it longer, consider freezing portions in a freezer-safe container for up to 3 months. For reheating, microwave the steak and veggies on high for about 2-3 minutes or until heated through. Note that the texture may soften slightly upon reheating, but a splash of water can help bring moisture back.
Chef’s Helpful Tips
- Avoid overcrowding the pan while searing the beef; cook in batches if necessary for the best sear.
- Make sure all ingredients are ready before you start; stir-frying happens quickly!
- If you prefer a spicier kick, consider adding sliced fresh chilies or a dash of red pepper flakes.
- Feel free to swap in other vegetables like snap peas or carrots based on your preference or what you have on hand.
- Marinating the beef longer than 30 minutes can enhance flavor but may cause it to break down too much, making it mushy if left too long.

Recipe FAQs
Can I use a different cut of steak?
Absolutely! If you prefer a leaner cut, flank steak or tenderloin can work well. Just remember to slice against the grain for tenderness.
What can I substitute for Shaoxing wine?
If you don’t have Shaoxing wine, using dry sherry or even a splash of rice vinegar can add a nice acidity to the dish. Just keep in mind that the flavor will slightly change.
How can I make this dish gluten-free?
You can easily make Panda Express Black Pepper Sirloin Steak gluten-free by using gluten-free soy sauce and ensuring that the oyster sauce is gluten-free as well.
Can I make this dish vegetarian?
Yes! You can swap the beef for firm tofu or tempeh. Adjust the cooking time accordingly, ensuring that any replacement is nicely browned and heated through before adding the sauce.
