This vibrant stir-fry combines thinly sliced beef with colorful peppers in a luscious soy-butter sauce, creating a dish that’s both comforting and exciting. Ready in about 30 minutes, it’s ideal for busy evenings when you crave something restaurant-quality at home.
Why This Recipe Captures Bold Flavors
The magic lies in the harmony of savory soy, tangy vinegar, and creamy butter that clings to every piece of beef and pepper. Marinating the beef ensures tenderness, while high-heat searing creates a caramelized crust. Blistered peppers add a subtle smokiness, making each bite memorable.
Essential Ingredients for Success
Gather these pantry staples and fresh produce for four servings:
- Beef: 1 lb thinly sliced New York strip or sirloin steak
- Marinade: 2 tbsp cornstarch, 2 tsp soy sauce, 2 tsp neutral oil like avocado
- Sauce base: 1/3 cup soy sauce, 1/4 cup oyster sauce (or hoisin), 2 tsp sugar, 1 tbsp white vinegar, 2 tsp cornstarch, 2 tsp black pepper, 2/3 cup water
- Aromatics and veggies: 6 green onions (separated), 12 oz shishito or mild peppers (halved), 6 garlic cloves (sliced), 1-inch ginger (chopped)
- Finish: 3 tbsp neutral oil (divided), 2 tbsp chilled butter (cubed)
- Serve with: Steamed rice
These components create layers of umami, heat, and silkiness.
Step-by-Step Cooking Guide
Follow these instructions for foolproof results.
Marinate the beef: In a bowl, mix beef slices with cornstarch, soy sauce, and oil. Let sit 15 minutes to 4 hours in the fridge. The cornstarch tenderizes and crisps the meat.
Prepare the sauce: Whisk soy sauce, oyster sauce, sugar, vinegar, cornstarch, pepper, and water. This thickens into a glossy coating.
Sear the beef: Heat 1 tbsp oil in a large skillet over medium-high. Add half the beef in a single layer; cook undisturbed 3-4 minutes until golden. Flip briefly if needed, then remove. Repeat with remaining beef.
Cook aromatics: In the same pan, add 1 tbsp oil. Sauté white/green onion parts 2 minutes until charred. Add peppers, garlic, ginger; stir 45 seconds until fragrant.
Combine and sauce: Return beef, pour in sauce. Cook 2 minutes until thickened. Off heat, stir in butter and dark green onions for emulsified shine.
Serve hot over rice.

Adapt to what you have on hand with these swaps:
| Original | Substitute | Notes |

| Oyster sauce | Hoisin or fish sauce | Hoisin adds sweetness |
| Avocado oil | Vegetable or canola | High smoke point essential |
Pro Tips for Restaurant-Worthy Results
- Slice thinly: Freeze beef 15 minutes for easier cutting; aim for 1/8-inch slices.
- Don’t overcrowd: Batch-cook beef to avoid steaming.
- High heat is key: Get the pan screaming hot for char without sogginess.
- Butter finish: Cold butter emulsifies best; stir off heat to prevent separation.
- Prep ahead: Marinate beef morning-of for deeper flavor.
