This dish features thinly sliced flank steak marinated and quickly seared in a hot wok. Colorful bell peppers and aromatic onions, garlic, and ginger are stir-fried to tender-crisp perfection. The savory sauce, blending soy, oyster, hoisin, and chili paste, coats the ingredients with a rich, spicy glaze. Garnished with spring onions, it delivers a lively balance of heat and umami in under 30 minutes, ideal for busy weeknights. Serve alongside jasmine rice or noodles for a satisfying dinner.

The first time I made this spicy beef and pepper stir fry, I was rushing after work, craving something that packed a punch but came together fast. The vibrant colors and bold flavors instantly won me over, turning a simple weeknight dinner into a little celebration of Asian-inspired goodness.

I clearly remember the first time unexpected guests dropped by, and I whipped this up with whatever I had in the fridge—the sauce came together perfectly, and everyone asked for seconds. That night confirmed this recipe was a keeper.

Ingredients

  • Beef: I always reach for flank steak sliced thin against the grain to keep it tender and easy to cook quickly.
  • Peppers and Vegetables: Using red, green, and yellow bell peppers not only adds color but balances sweetness and crunch perfectly.
  • Sauce Ingredients: A combo of soy sauce, oyster sauce, hoisin, and chili paste makes a savory, spicy, and slightly sweet glaze that sticks beautifully to the beef and veggies.
  • Oil & Seasoning: Vegetable oil withstands high heat nicely, and freshly ground black pepper adds that final little kick.

Instructions

Marinate the Beef:
Toss thinly sliced beef with cornstarch, soy sauce, and sesame oil. It helps the beef stay tender and gives the sauce something to cling to.
Prepare the Sauce:
Mix soy sauce, oyster sauce, hoisin, chili paste, brown sugar, and water. The blend is complex and keeps the dish vibrant.
Cook the Beef:
Heat oil in a wok over high heat and sear the beef quickly to lock in juices, then set aside.
Sauté Aromatics:
Throw in onions, garlic, and ginger—watch the enticing aroma fill your kitchen as they soften.
Add Peppers:
Stir-fry the colorful bell peppers just until tender-crisp to keep a nice bite.
Bring It All Together:
Return beef and its juices to the wok, pour in the sauce, and stir-fry until everything is coated and glossy.
Final Seasoning:
Sprinkle with freshly ground black pepper to taste and garnish with spring onions just before serving for a fresh finish.

One afternoon when feeling low, I made this stir fry, and the bold flavors lifted my mood instantly—this dish has become my comfort food that cheers me on no matter what.

Keeping It Fresh

Always slice your peppers and vegetables just before cooking to keep their freshness and crunch. If guests come over unexpectedly, fresh veggies make all the difference in taste and texture.

When You're Missing Something

If you don’t have oyster sauce, a bit of hoisin mixed with soy sauce can substitute in a pinch, keeping the flavor close to the original.

Serving Ideas That Clicked

This stir fry pairs wonderfully with jasmine rice or chewy rice noodles for a filling meal. I also like topping it with a sprinkle of toasted sesame seeds for an extra layer of flavor.

  • Always save some sauce to drizzle on the rice—it’s the best part!
  • Quick tip: stir-fry finishes best on high heat so keep that wok hot.
  • Leftovers taste great the next day, just reheat quickly to keep veggies crisp.
