Ingredients You’ll Need
Gathering the right ingredients is the first step toward nailing this Pepper Steak Stir Fry Recipe. Each component plays an important role, from the tender steak that offers richness, to the bright bell peppers providing crunch and color, and the sauce ingredients delivering that irresistible savory finish.
- Vegetable oil: Use a neutral oil for high-heat cooking to get a nice sear without burning.
- Red bell pepper: Adds a sweet crunch and vivid color that wakes up the plate.
- Green bell pepper: Offers a slightly bitter contrast that complements the sweetness of the red pepper.
- Flank steak: Thinly sliced for quick, even cooking; it’s lean and flavorful.
- Minced garlic: Brings aromatic depth and a gentle kick to the stir fry.
- Minced ginger: Adds warmth and zest to brighten the dish.
- Salt and pepper: Essential for seasoning the steak and balancing flavors.
- Soy sauce: The salty, umami base of the sauce that ties everything together.
- Sugar: Just enough sweetness to balance the savory and enhance the peppers.
- Cornstarch: Acts as a thickening agent to give the sauce its glossy consistency.
- Water: Helps to thin the sauce just right so it coats the ingredients beautifully.
How to Make Pepper Steak Stir Fry Recipe
Step 1: Heat the Oil
Start by heating 1 teaspoon of vegetable oil in a large skillet or pan over medium-high heat. You want the oil to shimmer but not smoke, setting the stage perfectly to stir fry those vibrant bell peppers.
Step 2: Cook the Peppers
Toss in the sliced red and green bell peppers and let them cook for about 3 to 4 minutes. The goal here is to soften them just enough so they’re tender but still have a slight crispness and a bit of char for added flavor complexity. Once ready, set the peppers aside so they don’t overcook while you focus on the steak.
Step 3: Sear the Steak
Add the remaining oil to the now empty pan and crank the heat to high. Season your thin flank steak slices with salt and pepper before adding them to the hot skillet. Let them cook undisturbed for a bit to develop a nice brown crust, then stir occasionally for about 5 to 6 minutes until the steak is cooked through but still tender.
Step 4: Add Garlic and Ginger
Once the steak is nearly done, stir in the minced garlic and ginger. These aromatics only need about 30 seconds of cooking to release their fragrances, infusing the dish with that signature punch without overpowering the other flavors.
Step 5: Combine Peppers and Steak
Return the cooked bell peppers back into the pan with the steak and aromatics. Give everything a good toss together, so the ingredients are evenly mixed and ready to be coated in the delicious sauce that’s about to come.
Step 6: Make the Sauce
Whisk together soy sauce, sugar, water, and cornstarch in a small bowl until smooth. This simple sauce is the magic behind the Pepper Steak Stir Fry Recipe—bringing balance with its sweet-salty notes and lovely thickness.
Step 7: Simmer and Thicken
Pour the sauce over the ingredients in your pan and bring to a gentle simmer over medium heat. Stir continuously for 2 to 3 minutes while the sauce thickens to a glossy finish, perfectly clinging to every bite of steak and bell pepper.
Step 8: Serve It Up
Once the sauce has thickened, the dish is ready to be served hot. Plate your Pepper Steak Stir Fry Recipe over fluffy steamed rice or noodles, and get ready to enjoy a satisfying, restaurant-quality meal at home.

FAQs
Can I use a different cut of beef for this recipe?
Absolutely! While flank steak is perfect for its leanness and tenderness, sirloin or skirt steak can also work well. Just be sure to slice the beef thinly against the grain for the best results.
Is it necessary to use both red and green bell peppers?
Not necessarily. Using both adds a wonderful balance of sweetness and slight bitterness, plus vibrant color, but feel free to use just one type depending on what you have available or your preferences.
Can I make this recipe vegetarian?
Yes, simply swap the steak for firm tofu or seitan and omit or replace the soy sauce with a vegetarian-friendly alternative. The peppers and sauce still deliver plenty of flavor and texture without meat.
How spicy is this Pepper Steak Stir Fry Recipe?
This recipe itself isn’t spicy, but if you love heat, you can easily add chili flakes or a splash of chili garlic sauce during the cooking process to give it a fiery kick.
What should I serve with this stir fry for a complete meal?
Serving it over steamed rice or noodles is classic and filling. Adding a side of steamed or sautéed veggies makes it a balanced and colorful meal everyone will enjoy.
