- 1 tablespoon vegetable oil, divided: Used for cooking to get a nice sear on the steak and to sauté the peppers just right.
- 1 red bell pepper, cored, seeded, and cut into strips: Adds a sweet crunch and vibrant color.
- 1 green bell pepper, cored, seeded, and cut into strips: Brings a slightly grassy, fresh bite along with vivid green hues.
- 1 1/4 pounds flank steak, thinly sliced: The protein star of the dish; flank steak’s texture and flavor really soak up the sauce.
- 2 teaspoons minced garlic: Delivers deep, aromatic pungency that perks up the entire stir fry.
- 1 teaspoon minced ginger: Adds warmth and a subtle hint of spice that brightens the profile.
- Salt and pepper to taste: To season and enhance every component perfectly.
- 1/4 cup soy sauce: Provides umami richness and saltiness to the sauce base.
- 1 1/2 tablespoons sugar: Balances the salt with a touch of sweetness.
- 1 1/2 tablespoons cornstarch: Thickens the sauce for that glossy finish that clings to the meat and veggies.
- 1/4 cup water: Helps blend and thin out the sauce ingredients for the perfect consistency.
How to Make Pepper Steak Stir Fry Recipe
Step 1: Heat Oil
Start by warming 1 teaspoon of vegetable oil over medium-high heat in a large pan or skillet until it’s shimmering. This little bit of oil creates the perfect surface to gently char the bell peppers and bring out their natural sweetness.
Step 2: Cook Peppers
Add the red and green bell pepper strips to the hot pan. Let them cook for 3 to 4 minutes, stirring occasionally, until they become just tender but still hold a satisfying crunch and develop those lovely, slightly charred edges. Once done, remove them from the pan and set aside. This step locks in their bright flavor and vibrant color.
Step 3: Cook Steak
Next, add the remaining vegetable oil to the pan and turn the heat up to high. Season your thinly sliced flank steak with salt and pepper, then add it to the pan in a single layer if possible. Let the steak cook for 5 to 6 minutes, stirring occasionally so it browns evenly but remains juicy and tender inside.
Step 4: Add Aromatics
Once your steak is nearly done, toss in the minced garlic and ginger. Cooking these for about 30 seconds releases their enticing aroma without burning, instantly transforming the dish with layers of flavor.
Step 5: Combine Peppers and Steak
Return the cooked bell peppers to the pan with the steak and aromatics, stirring well so everything is evenly mixed. This step unites the flavors and readies your stir fry for the sauce.
Step 6: Prepare Sauce
In a small bowl, whisk together the soy sauce, sugar, water, and cornstarch until smooth and lump-free. This simple sauce packs an incredible punch, coating each ingredient perfectly without being overpowering.
Step 7: Simmer and Thicken
Pour the sauce mixture into the pan. Bring it to a simmer over medium heat and cook for 2 to 3 minutes. As it thickens and turns glossy, it will cling wonderfully to the steak and peppers, giving the dish that irresistible sheen and full-bodied taste.
Step 8: Serve
Your Pepper Steak Stir Fry Recipe is now ready! Serve it hot right from the skillet, ideally over freshly steamed rice or your favorite noodles to soak up every bit of that luscious sauce.

Make Ahead and Storage
Storing Leftovers
Place any leftover stir fry in an airtight container and refrigerate for up to 3 days. The meat and vegetables keep their texture well, and the flavors even deepen overnight, making for a delicious next-day meal.
Freezing
If you want to keep it longer, transfer the cooled stir fry to a freezer-safe container or zip-top bag and freeze for up to 2 months. When you’re ready, thaw it overnight in the fridge before reheating.
Reheating
To reheat, warm the stir fry in a skillet over medium heat, stirring occasionally until hot and bubbly. Add a splash of water or broth if the sauce has thickened too much. Avoid microwaving for best texture and flavor, but if you’re short on time, use short bursts and stir well.
FAQs
Can I use a different cut of beef for this recipe?
Absolutely! While flank steak is perfect because it’s lean and tender when sliced thin, you can also use skirt steak, sirloin, or even thinly sliced ribeye. Just aim for cuts that cook quickly and remain tender.
What can I substitute for soy sauce if I’m gluten-free?
Gluten-free tamari is a fantastic alternative that keeps the rich umami flavor without the gluten. Coconut aminos also work well if you want a slightly sweeter and less salty option.
Is it possible to make this recipe vegetarian?
Definitely! Swap the flank steak with firm tofu or seitan and use vegetable broth instead of water in the sauce. Just be mindful to cook your protein separately before adding the peppers and sauce.
How do I prevent the bell peppers from becoming mushy?
Cook the peppers over medium-high heat just briefly until they’re tender but still crisp—about 3 to 4 minutes. Avoid overcrowding the pan to ensure they char nicely instead of steaming.
Can I make this stir fry spicier?
Yes! Add some thinly sliced fresh chili peppers while cooking the steak or sprinkle chili flakes into the sauce. A dash of Sriracha or chili garlic sauce mixed into the sauce works well, too.
