Ingredients
- 1 tablespoon vegetable oil (divided for sautéing peppers and searing steak)
- 1 red bell pepper (cored, seeded, and cut into strips)
- 1 green bell pepper (cored, seeded, and cut into strips)
- 1 1/4 pounds flank steak (thinly sliced)
- 2 teaspoons minced garlic (fresh)
- 1 teaspoon minced ginger
- Salt and pepper to taste
- 1/4 cup soy sauce (low-sodium recommended)
- 1 1/2 tablespoons sugar
- 1 1/2 tablespoons cornstarch
- 1/4 cup water
Instructions
- Step 1: Prepare the bell peppers by cutting them into thin strips to ensure quick and even cooking. Gathering your ingredients beforehand will make the cooking process smoother.
- Step 2: Heat 1 teaspoon of vegetable oil over medium-high heat in a skillet. Sauté the peppers for 3-4 minutes until tender but still slightly crisp, then transfer them to a plate to prevent overcooking.
- Step 3: Add the remaining oil to the skillet. Season the sliced steak with salt and pepper. Increase heat to high and cook the steak for 5-6 minutes, stirring occasionally, until browned and crusty.
- Step 4: Add minced garlic and ginger to the steak. Stir for about 30 seconds until fragrant.
- Step 5: Return the peppers to the skillet. In a small bowl, whisk together soy sauce, sugar, cornstarch, and water. Pour the sauce over the steak and peppers, then simmer for 2-3 minutes until the sauce thickens and coats everything evenly.
Tips & Variations
- Partially freeze the flank steak for 20-30 minutes before slicing; this makes it easier to cut thin strips.
- Use a mix of bell pepper colors, such as yellow or orange, for added sweetness and vibrant presentation.
- Serve over steamed rice or noodles to soak up the delicious sauce.
Storage
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over medium heat or in the microwave, stirring occasionally to maintain texture. Avoid overcooking during reheating to keep the steak tender.

Meat
- 1 1/4 pounds flank steak, thinly sliced (partially freeze for 20–30 minutes to make slicing easier)

- 1 teaspoon minced ginger
- Salt and pepper to taste
- 1/4 cup low-sodium soy sauce
- 1 1/2 tablespoons sugar
- 1 1/2 tablespoons cornstarch
- 1/4 cup water
Oils
- 1 tablespoon vegetable oil, divided
Instructions
- Prepare the peppers: Cut the red and green bell peppers into thin strips to ensure quick and even cooking. Having all ingredients prepped beforehand makes the stir fry easier and faster.
- Sauté the peppers: Heat 1 teaspoon of vegetable oil in a skillet over medium-high heat. Add the bell pepper strips and sauté for 3-4 minutes until they become just tender but retain some crispness. Remove the peppers from the skillet and set aside on a plate to prevent overcooking.
- Cook the steak: Add the remaining 2 teaspoons of vegetable oil to the skillet and season the thinly sliced flank steak with salt and pepper. Increase the heat to high and cook the steak for 5-6 minutes, stirring occasionally, until it develops a nice brown crust.
- Add aromatics: Stir in the minced garlic and ginger to the steak in the skillet. Cook and stir for about 30 seconds to release their aroma and enhance the overall flavor.
- Combine and make sauce: Return the sautéed peppers to the skillet with the steak. In a small bowl, whisk together the soy sauce, sugar, cornstarch, and 1/4 cup water until smooth. Pour this sauce over the meat and vegetables, then simmer for 2-3 minutes until the sauce thickens and evenly coats the stir fry.
Notes
- Partially freezing the flank steak before slicing makes it easier to cut thin strips.
- Using low-sodium soy sauce helps control the saltiness of the dish.
- Do not overcook the bell peppers; they should remain slightly crisp for the best texture.
- Serve immediately over steamed rice or noodles for a complete meal.
- You can substitute flank steak with sirloin or skirt steak if preferred.
