Common Mistakes to Avoid
- Slicing the steak with the grain — Always cut against the grain for more tender bites.
- Overcrowding the pan — Too much beef at once can cause steaming instead of proper browning.
- Using low heat — Stir-frying works best over medium-high to high heat for browned beef and crisp vegetables.
- Overcooking the vegetables — Cook them until crisp-tender so they retain their texture.
Required Equipment
- Large wok or skillet — Provides enough surface area for quick, high-heat stir-frying.
- Sharp chef’s knife — Makes it easier to slice the flank steak thinly and evenly.
- Cutting board — Provides a stable surface for safely preparing the steak and vegetables.
- Mixing bowl — Makes marinating and seasoning the beef convenient.
- Tongs — Help turn and remove the steak without breaking the pieces apart.
Storage Instructions
Allow the cooked pepper steak to cool slightly before transferring it to a shallow airtight container. Refrigerate leftovers for up to 3–4 days.
For longer storage, freeze individual portions in freezer-safe airtight containers or freezer bags for up to 2 months. Thaw overnight in the refrigerator before reheating.
Reheat gently in a skillet over medium heat until steaming hot. Avoid prolonged reheating because the flank steak can become tougher. The protein content remains essentially unchanged during normal refrigerated or frozen storage.

📝 Ingredients
For the Steak

- 1 teaspoon sesame oil
- ½ teaspoon freshly ground black pepper
For the Stir-Fry
- 1 tablespoon avocado or neutral cooking oil
- 1 medium yellow onion, sliced
- 1 medium green bell pepper, sliced
- 1 medium red bell pepper, sliced
- 3 cloves garlic, minced
- 1 teaspoon fresh ginger, grated
For the Sauce
- 2 tablespoons low-sodium soy sauce
- ¼ cup low-sodium beef broth
- 1 tablespoon rice vinegar
- 1 teaspoon sesame oil
- ½ teaspoon black pepper
- ½ teaspoon zero-calorie sweetener or 1 teaspoon honey — optional
- 1 teaspoon cornstarch mixed with 1 tablespoon cold water — optional, for thickening

Directions
- Slice and season the steak.
Cut the flank steak into very thin strips against the grain. Toss with 2 tablespoons soy sauce, sesame oil, black pepper, and optional cornstarch. Let it rest for 10 minutes while preparing the vegetables. - Prepare the sauce.
In a small bowl, whisk together soy sauce, beef broth, rice vinegar, sesame oil, black pepper, and optional sweetener. Set aside. - Heat the pan.
Place a large wok or skillet over high heat for about 1–2 minutes. Add the cooking oil and allow it to become hot but not smoking. - Sear the beef.
Add the steak in a single layer. Cook for approximately 2–3 minutes per side, turning as needed, until browned on the outside and cooked through. Work in batches if necessary to prevent overcrowding. Transfer the steak to a plate. - Stir-fry the vegetables.
Reduce the heat slightly to medium-high. Add the onion and bell peppers and stir-fry for 3–4 minutes. They should become slightly softened while retaining some crispness. - Add garlic and ginger.
Add the minced garlic and grated ginger. Stir constantly over medium-high heat for about 30–45 seconds, just until fragrant. - Return the beef.
Add the cooked steak back to the pan and pour in the prepared sauce. Stir everything together over medium-high heat for 1–2 minutes. - Thicken the sauce if desired.
If using the cornstarch slurry, pour it in while stirring. Cook for approximately 30–60 seconds, until the sauce becomes glossy and lightly thickened. - Check the texture.
The beef should be tender and coated in a shiny savory sauce, while the peppers and onions should remain slightly crisp. - Serve immediately.
Serve hot on its own for a lower-carb meal or over cauliflower rice for additional volume without traditional rice.
High-protein cooking tip: Avoid overcooking the flank steak. Quick cooking over high heat followed by a short finish in the sauce helps maintain a more tender texture.
