This vibrant stir fry combines thinly sliced flank steak with crisp bell peppers in a bold, savory-spicy sauce. The beef is marinated briefly to tenderize, then quickly cooked over high heat to achieve a perfect sear while vegetables remain crisp. Garlic, ginger, and onion build an aromatic base, balanced with soy, oyster, and hoisin sauces plus chili heat. The entire dish comes together in just 25 minutes, making it ideal for weeknight cooking.

The sizzle of the wok on a Tuesday night changed our dinner routine forever. I first stumbled upon this stir fry recipe when we had bell peppers threatening to wrinkle in the crisper drawer and beef that needed using. The kitchen windows fogged as aromas of ginger and garlic filled our apartment, making my partner wander in from the living room asking what smelled so incredible.

Last month when my sister visited with her picky eaters, I served this stir fry as a last-minute dinner solution. The kitchen buzzed with conversation as I sliced peppers, the bright colors catching my nephews attention. Even the kids who typically push vegetables around their plates cleaned up every last bite, asking if they could help cook it next time.

Ingredients

  • Flank steak: Slice it paper-thin against the grain while its still slightly frozen for that melt-in-your-mouth texture I discovered after years of tough stir fry meat.
  • Bell peppers: Using different colors isnt just for appearance, each brings a slightly different sweetness level that creates depth of flavor.
  • Ginger: Fresh ginger stores beautifully in the freezer, where you can grate it directly into the pan without even thawing it first.
  • Chili garlic sauce: This little jar changed my cooking life, bringing complex heat that basic hot sauce cant match.

Instructions

Marry the marinade:
Toss your sliced beef with soy sauce, cornstarch, rice wine, and sesame oil, then let it rest for 10 minutes. The cornstarch does magic here, creating that silky coating that clings to the meat.
Sauce preparation:
Whisk together soy sauce, oyster sauce, hoisin, chili garlic sauce, sugar and water in a small bowl. Having this ready before cooking starts prevents that frantic cabinet-searching mid-stir fry.
Flash fry the beef:
Get your wok screaming hot before adding oil and the marinated beef. Listen for that immediate sizzle and keep everything moving for just 2-3 minutes until barely browned.
Aromatics first:
With fresh oil in the hot pan, add garlic, ginger and onion just until fragrant. Your kitchen will suddenly smell like your favorite takeout place.
Pepper party:
Toss in all those colorful bell peppers and keep them moving in the hot pan. Youre looking for that perfect tender-crisp texture where they still have some life in them.
Reunion and sauce:
Bring the beef back to join the vegetable party, then pour that waiting sauce over everything. Watch it bubble and thicken almost immediately as you toss everything together.
Finish with freshness:
Remove from heat and scatter those green spring onions over everything. The residual heat will soften them just enough to release their aroma without losing their color.

One rainy evening when our power flickered during a storm, I was halfway through making this stir fry. We ended up finishing it by flashlight, laughing as we took turns holding the light while the other stirred. Even in near-darkness, the dish turned out perfectly, and now whenever the forecast calls for storms, someone inevitably suggests making our blackout beef and peppers.

Make Ahead Options

Ive learned that slicing the beef and prepping the vegetables the night before turns this from a 25-minute meal into a 12-minute miracle. The marinating time while the wok heats is enough to flavor the meat, and having everything in separate containers ready to go creates that satisfying cooking show feeling where everything flows effortlessly.

Serving Suggestions

While jasmine rice is my go-to companion, Ive discovered this stir fry works beautifully over so many bases. My husband prefers it with udon noodles tossed right into the pan at the end, while my health-conscious friend serves hers over cauliflower rice. For a complete meal experience, I sometimes add a side of quick-pickled cucumbers for a cool contrast to the spicy beef.

Customization Ideas

The beauty of this recipe lies in its adaptability to whatever your refrigerator happens to contain. One memorable evening when peppers were scarce, I substituted thinly sliced zucchini, mushrooms, and snow peas, creating an entirely new dish with the same fantastic sauce.

  • For a lower-carb version, try serving over spiralized zucchini noodles that barely need cooking.
  • Leftover roasted vegetables from another meal can be chopped and tossed in during the final minute for an entirely different texture experience.
  • For meat-free Mondays, extra-firm tofu pressed and cubed works beautifully with the same marinade ingredients.

Recipe FAQs

Yes, flank steak works best for its tenderness and quick cooking, but sirloin, skirt steak, or ribeye also work well. Slice against the grain for maximum tenderness, and avoid tougher cuts like chuck.

Slice the beef thinly against the grain and marinate for at least 10 minutes. Don't overcook during the first stir fry—remove it when browned but still slightly underdone, then finish cooking after adding the sauce.

A large skillet or cast-iron pan works perfectly. The key is using high heat and working in batches if needed to avoid overcrowding, which prevents proper searing and browning.

You can prep ingredients in advance—slice vegetables and beef, and prepare the marinade and sauce. However, stir fry is best cooked fresh and served immediately for optimal texture and heat retention.

The heat level depends on your chili garlic sauce amount. Start with 1 tablespoon and adjust upward for more spice. Fresh sliced chili or additional Sriracha can boost heat further.

Serve over steamed jasmine or basmati rice, or pair with noodles for a heartier meal. Spring onions and sesame seeds add fresh garnish and nutty flavor.
