Ingredients You’ll Need

Here’s what goes into this sizzling skillet meal:

1 lb flank steak or sirloin, thinly sliced against the grain
2 tbsp cornstarch
2 tbsp soy sauce
2 tbsp sesame oil
1 large onion, sliced
1 red bell pepper, sliced

Each of these ingredients plays a critical role. The cornstarch tenderizes the meat and creates that glossy, restaurant-style finish. Sesame oil provides deep, nutty undertones that pair perfectly with the soy sauce. And the onions and peppers add crunch, sweetness, and color to the dish.

Equipment Needed

To whip up this stir-fry at home, you’ll need:

A sharp chef’s knife (for thinly slicing the steak and veggies)
A cutting board
Large mixing bowl (for marinating the meat)
Wok or large nonstick skillet
Tongs or a spatula
Measuring spoons

Optional but helpful: paper towels for patting the beef dry, and a lid if you want to steam the veggies slightly at the end.

Step-by-Step Directions

Prep the Beef
Start by thinly slicing the flank steak or sirloin against the grain. This ensures a tender bite every time. Place the slices in a bowl and toss with cornstarch until well coated. Add the soy sauce and mix thoroughly to marinate for at least 10 minutes while you prep the vegetables.
Slice the Vegetables
While the beef is marinating, slice your onion and red bell pepper into thin strips. Keep them similar in size to ensure even cooking.
Heat the Skillet
In a large wok or nonstick skillet, heat the sesame oil over medium-high heat until shimmering. Add the marinated beef in a single layer and cook undisturbed for 2–3 minutes to get a good sear. Flip and cook for another 1–2 minutes until browned and nearly cooked through. Remove beef and set aside.
Sauté the Veggies
In the same skillet, add a touch more oil if needed and toss in the onions and bell peppers. Stir-fry for 3–4 minutes until just tender but still crisp.
Combine and Sizzle
Return the cooked beef to the pan with the veggies. Stir-fry everything together for another 1–2 minutes to meld the flavors. Taste and adjust with extra soy sauce or a dash of pepper if desired.
Serve Hot
Plate the sizzling pepper steak over a bed of steamed rice or noodles and enjoy immediately!

Tips and Tricks for the Best Pepper Steak

Cut against the grain: This is crucial for a tender texture. Look at the natural lines of the meat and slice perpendicular to them.
Don’t overcrowd the pan: If your pan is small, sear the beef in batches to keep it from steaming.
Add aromatics: Garlic and ginger can be stir-fried with the veggies for an added flavor punch.
Spice it up: Like it hotter? Add a sliced chili pepper or a dash of chili garlic sauce during the final stir.

Variations and Substitutions

This recipe is highly versatile. Here are some creative ways to make it your own:

Use chicken or tofu instead of beef for a different protein option.
Add more vegetables such as snow peas, broccoli, or mushrooms.
Swap soy sauce for tamari to make it gluten-free.
Try hoisin sauce or oyster sauce for a richer, slightly sweet twist.
Make it low-carb by serving it over cauliflower rice or lettuce wraps.

Storage & Leftovers

This pepper steak makes excellent leftovers! Store any extra portions in an airtight container in the fridge for up to 3–4 days. Reheat in a skillet over medium heat or microwave in 30-second bursts until warmed through. The sauce may thicken in the fridge—add a splash of water or broth to loosen it up during reheating.

Freezing Tips: While it’s best fresh, you can freeze the cooked dish for up to 2 months. Let it thaw overnight in the fridge before reheating.

What to Serve With Chinese Pepper Steak

Looking to round out the meal? Try these simple pairings:

Steamed jasmine rice – The perfect blank canvas to soak up the sauce.
Garlic noodles – For an extra-savory base.
Stir-fried greens – Bok choy, Chinese broccoli, or spinach are excellent options.
Egg rolls or dumplings – For a festive, takeout-style experience.
Light white wine like Riesling or a cold Tsingtao beer – Ideal for balancing the bold flavors.

FAQs

Can I use a different cut of beef?

Yes! Flank steak and sirloin are preferred for their tenderness, but skirt steak or even ribeye can work well. Just be sure to slice thinly against the grain.

Is this dish spicy?

Not inherently, but you can easily make it spicy by adding chili flakes, fresh chilies, or chili oil.

Can I make this vegetarian?

Absolutely. Replace the beef with tofu or a plant-based meat substitute. Just be sure to press the tofu and pan-fry it until golden before adding it to the stir-fry.

What’s the best oil for stir-frying?

Sesame oil adds authentic flavor but has a low smoke point. If you’re cooking at very high heat, use neutral oils like canola or avocado oil and finish with a drizzle of sesame oil at the end.

Can I make this ahead of time?

Yes! You can prep the beef and veggies in advance and store them separately in the fridge. When ready to eat, just cook everything fresh for the best texture and flavor.
