Ingredients:
- 1 lb flank steak, thinly sliced against the grain
- 1 red 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
Preparation and Marination
Preparing the Steak
The first step in creating a fantastic Pepper Steak with Bell Peppers and Onion is to properly prepare the flank steak. For the most tender results, it’s crucial to slice the steak thinly against the grain. This means looking for the direction of the muscle fibers and cutting across them. You can even partially freeze the steak for about 30 minutes before slicing; this makes it much firmer and easier to get those super thin, uniform slices. Aim for slices that are about 1/8 to 1/4 inch thick. This thinness is key to ensuring the steak cooks quickly and remains tender.
Marinating the Steak
Once your flank steak is sliced, we’ll give it a quick marinade to boost its flavor and tenderness. In a medium bowl, combine the thinly sliced flank steak with half of the soy sauce (that’s 2 tablespoons), half of the oyster sauce (1 tablespoon), and the minced garlic and grategin extractresh ginger. Make sure all the steak slices are well coated. Let this marinate for at least 15 minutes at room temperature, or up to 30 minutes in the refrigerator if you have a bit more time. This short marination period allows the flavors to penetrate the meat without making it mushy.
Preparing the Sauce and Vegetables
While the steak is marinating, let’s get everything else ready. In a separate small bowl, whisk together the remaining soy sauce (2 tablespoons), the remaining oyster sauce (1 tablespoon), the rice vinegar, and the honey or brown sugar. This is our flavor base for the sauce. In another tiny bowl, prepare a cornstarch slurry by whisking together the cornstarch and the 2 tablespoons of water until it’s smooth and there are no lumps. This slurry will be used to thicken our sauce later. Next, slice your bell peppers and onion. Aim for consistent, thin slices for both the red, green, and yellow bell peppers, and the medium onion. Uniformity in slicing ensures that all the vegetables cook evenly.
Cooking the Pepper Steak
Searing the Steak
Now for the cooking! Heat a large skillet or wok over high heat. Add 1 tablespoon of the vegetable oil and let it get very hot. You want it to be shimmering. Carefully add the marinated steak in a single layer. Avoid overcrowding the pan; if necessary, cook the steak in batches. This is crucial for achieving a good sear. Sear the steak for about 1 to 2 minutes per side, until it’s nicely browned and just cooked through. Don’t overcook it, as it will continue to cook slightly in the sauce. Once seared, remove the steak from the skillet and set it aside on a clean plate.
Stir-frying the Vegetables
Add the remaining 1 tablespoon of vegetable oil to the same hot skillet. Now, add your sliced bell peppers and onion. Stir-fry them over medium-high heat for about 3 to 5 minutes, or until they are tender-crisp. You want them to still have a slight bite and vibrant color, not be completely mushy. Keep them moving in the pan to ensure even cooking. If your skillet seems a little dry, you can add a splash of water or a tiny bit more oil, but be careful not to make it greasy.
Combining and Finishing the Dish
Return the seared steak to the skillet with the stir-fried vegetables. Pour the prepared sauce mixture over everything. Stir well to combine and bring the mixture to a simmer. Once simmering, give the cornstarch slurry a quick re-stir (cornstarch settles quickly) and then slowly pour it into the skillet while stirring continuously. Continue to stir and cook for another 1 to 2 minutes, or until the sauce has thickened to your desired consistency. It should coat the back of a spoon nicely. Finally, stir in the sesame oil for that fragrant finishing touch. This is where all the flavors meld together perfectly. Serve immediately over steamed rice for a complete and satisfying meal.
