Ingredients:
- 1 lb flank steak, thinly sliced against the grain
- 1 red bell pepper, thinly sliced
- 1 green bell pepper, thinly sliced
- 1 yellow bell pepper, thinly sliced
- 1 medium onion, thinly sliced
- 2 tbsp vegetable oil
- ¼ cup soy sauce
- 2 tbsp oyster sauce
- 1 tbsp cornstarch
- 2 tbsp water
- 1 tbsp rice vinegar
- 1 tbsp honey or brown sugar
- 2 cloves garlic, minced
- 1 tsp grated fresh gin extractger
- 1 tsp sesame oil
Preparing the Pepper Steak
Marinating the Steak
The first crucial step to achieving tender and flavorful Pepper Steak with Bell Peppers and Onion is to properly prepare and marinate the flank steak. Take your thinly sliced flank steak and place it in a medium-sized bowl. In a separate small bowl, whisk together the soy sauce, oyster sauce, rice vinegar, honey or brown sugar, minced garlic, and grategin extractresh ginger. This mixture will form the base of your marinade, infusing the steak with delicious umami and a hint of sweetness. Pour this marinade over the sliced steak, ensuring each piece is well-coated. Gently toss the steak with your hands or a spoon to distribute the marinade evenly. For the best results, cover the bowl with plastic wrap and let it marinate in the refrigerator for at least 30 minutes. This allows the flavors to penetrate the meat and the acidic components (from the ricgin extractinegar) to begin tenderizing it. If you have more time, marinating for up to 2 hours will yield even more tender and flavorful results.
Preparing the Vegetables
While the steak is marinating, it’s time to get your vegetables ready. This is where the vibrant colors and fresh crunch of our Pepper Steak with Bell Peppers and Onion come in. Take your red, green, and yellow bell peppers and carefully slice them into thin, uniform strips. The goal is to have them roughly the same size as your steak slices for even cooking. Next, take your medium onion and slice it thinly as well, creating half-moon shapes or rings depending on your preference. Having all your vegetables prepped and ready before you start cooking is essential, as stir-frying happens quickly. This preparation stage ensures that you can add ingredients to the hot pan without delay, preventing overcooking and maintaining that desirable crisp-tender texture.
Cooking the Pepper Steak
Searing the Steak
Now for the main event! Heat a large skillet or wok over medium-high heat. Add the vegetable oil and allow it to get nice and hot. You’ll know it’s ready when it shimmers slightly. Carefully add the marinated steak to the hot pan in a single layer. It’s important not to overcrowd the pan, as this will steam the meat instead of searing it, resulting in a less desirable texture. If necessary, cook the steak in batches. Sear the steak for about 1-2 minutes per side, or until it’s nicely browned and just cooked through. We’re aiming for a beautiful caramelization on the outside while keeping the inside tender. Once cooked, remove the steak from the pan and set it aside on a plate. Don’t worry about any browned bits stuck to the bottom of the pan – those are packed with flavor!
Stir-frying the Vegetables
With the steak set aside, it’s time to bring in those beautiful bell peppers and onions. Add a touch more vegetable oil to the same skillet if needed, and return it to medium-high heat. Add the sliced onions to the hot pan and stir-fry for about 2-gin extractinutes, until they begin to soften and turn slightly translucent. Next, add the thinly sliced red, green, and yellow bell peppers to the pan. Continue to stir-fry for another 3-5 minutes, or until the peppers are tender-crisp. You want them to have a slight bite to them, not be mushy. This is where the dish gets its name and its vibrant appeal. The colors will intensify as they cook, creating a visually stunning and delicious component to our Pepper Steak with Bell Peppers and Onion.
Finishing the Dish
In a small bowl, whisk together the cornstarch and water until it forms a smooth slurry. This will be our thickening agent, creating a glossy sauce that coats everything beautifully. Pour this cornstarch slurry into the skillet with the vegetables. Stir continuously as the sauce thickens, which should only take about 30 seconds to a minute. Once the sauce has thickened, return the seared steak to the pan. Add the sesame oil, which provides a wonderful nutty aroma and flavor. Toss everything together to coat the steak and vegetables evenly in the thickened sauce. Cook for another minute, allowing the steak to heat through and the flavors to meld. This final step brings all the elements of your Pepper Steak with Bell Peppers and Onion together into a cohesive and mouthwatering dish. Serve immediately.
