How to Make Pepper Steak Stir Fry Recipe
Step 1: Heat the Oil
Start by heating 1 teaspoon of vegetable oil over medium-high heat in a large skillet or pan until it shimmers. This ensures a hot surface for searing the bell peppers, which is crucial for achieving that slight char and softened texture that makes them irresistible.
Step 2: Cook the Peppers
Add the sliced red and green bell peppers to the hot pan. Let them cook undisturbed for about 3-4 minutes, just enough to soften while still retaining their crunch and to develop a bit of caramelized char for extra flavor. Once done, remove and set them aside—this keeps the peppers from overcooking later.
Step 3: Cook the Steak
Next, add the remaining oil to the pan and season your thinly sliced flank steak with salt and pepper. Turn the heat up to high and add the steak slices in a single layer if possible, allowing them to brown nicely. Stir occasionally, and cook for around 5-6 minutes until the steak is nicely seared and cooked through. This high heat method locks in juices and flavor.
Step 4: Add Aromatics
Reduce the heat slightly and toss in the minced garlic and ginger with the steak. Stir continuously for about 30 seconds until you can smell that fragrant, mouth-watering aroma spreading through the kitchen. This step infuses the steak with vibrant herbal notes that create a fantastic flavor foundation.
Step 5: Combine Peppers and Steak
Return your cooked red and green peppers to the pan. Stir everything together so the simplicity of the bell peppers and the seasoned steak marry perfectly, creating an enticing mix of colors and tastes in your pan.
Step 6: Prepare the Sauce
In a small bowl, whisk together the soy sauce, sugar, water, and cornstarch until the mixture is completely smooth. This blend is the magic that turns into a luscious, thick sauce that coats every morsel in the Pepper Steak Stir Fry Recipe.
Step 7: Simmer and Thicken
Pour the sauce into your skillet and bring it to a gentle simmer over medium heat. Keep stirring as the sauce thickens and becomes glossy, about 2 to 3 minutes. This step is key because it allows the flavors to concentrate and the sauce to cling beautifully to both steak and peppers.
Step 8: Serve Hot
Once your sauce has reached that perfect consistency, turn off the heat and serve immediately over steamed rice or noodles. The warm sauce, tender meat, and crisp-tender peppers create a harmonious bite each time.
How to Serve Pepper Steak Stir Fry Recipe

Garnishes
Fresh garnishes elevate this dish in delightful ways. Consider sprinkling thinly sliced green onions or toasted sesame seeds on top for a little crunch and extra aroma. A few fresh cilantro leaves can also bring a fresh herbal lift that brightens the final plate.
Side Dishes
If you want to round out your meal, simple steamed jasmine rice is a classic choice that soaks up all the wonderful sauce. Alternatively, serve this over warm egg noodles for a comforting texture contrast, or toss with some quick stir-fried greens like bok choy or snap peas for extra veggies.
Creative Ways to Present
For a fun twist, try serving the stir fry inside lettuce cups for a fresh, hand-held version. You can also plate it atop cauliflower rice or throw it over a bed of quinoa to boost the protein content and add another layer of texture and flavor.
Make Ahead and Storage
Storing Leftovers
After your Pepper Steak Stir Fry Recipe has cooled, transfer leftovers to an airtight container and keep refrigerated for up to 3 days. The flavors actually deepen after sitting, so leftovers can be just as delicious the next day!
Freezing
While best enjoyed fresh, you can freeze the cooked steak and peppers in a freezer-safe container for up to 1 month. Keep in mind the vegetables might lose some crunch after thawing, so this works better if you plan to reheat and serve with freshly cooked rice or noodles.
Reheating
To reheat, gently warm the stir fry in a skillet over medium heat or microwave until heated through. Stir occasionally to redistribute the sauce and avoid overcooking the steak. Adding a sprinkle of water or a quick splash of soy sauce can revive the dish nicely.
FAQs
Can I use a different cut of beef for this recipe?
Absolutely! While flank steak works wonderfully because it cooks quickly and remains tender when sliced thin, you can also use skirt steak or sirloin. Just be sure to slice the meat thinly against the grain for the best texture.
Is this Pepper Steak Stir Fry Recipe spicy?
This recipe is not spicy by default, but you can easily add some heat by tossing in a pinch of red pepper flakes or a dash of chili garlic sauce when adding the garlic and ginger. It’s a great way to customize the dish to your heat preference.
What can I substitute for soy sauce?
If you need a gluten-free or low-sodium option, tamari or coconut aminos work beautifully. They maintain the umami depth without overwhelming the dish.
Can I make this recipe vegetarian?
Definitely! Swap the steak with firm tofu, tempeh, or even seitan. Just make sure to press and slice firm tofu well and use a bit of extra vegetable oil to get a nice sear. The sauce pairs just as well with these alternatives.
How do I get the steak tender and not chewy?
The key is slicing the flank steak thinly against the grain and cooking it quickly over high heat. Overcooking can cause toughness, so keep an eye on the time and aim for a nice sear without drying out the meat.
