Protein
- 8 ounces flank steak or sirloin, thinly sliced against the grain
Vegetables
- 1 red bell pepper, sliced into strips
- 1 green bell pepper, sliced into strips
- 1 yellow bell pepper, sliced into strips
- 2 cloves garlic, finely chopped
- 1 small onion, finely chopped
Sauce
- 2 tablespoons soy sauce
- 1/2 cup beef broth
- 1 teaspoon cornstarch
Other Ingredients
- 2 tablespoons olive oil or vegetable oil
- Freshly cracked black pepper, to taste
- Salt, to taste
- Prep your ingredients: Thinly slice the steak against the grain to ensure tenderness. Cut bell peppers into uniform strips, finely chop garlic and onions, and measure out your liquids so everything is ready before heating the pan.
- Sear the steak: Heat oil in a large skillet over medium-high heat. Quickly sear the steak strips until browned but not fully cooked, about 2 minutes. Remove from skillet and set aside to maintain juiciness.
- Sauté vegetables: In the same skillet, add more oil if needed, then sauté the onion and garlic until fragrant and softened. Add bell peppers and cook for about 3 minutes until crisp-tender but still vibrant.
- Create the sauce and combine: Return the steak to the skillet. Mix soy sauce, beef broth, and cornstarch together, then pour over the steak and vegetables. Stir constantly as the sauce thickens and coats everything evenly, about 2-3 minutes.
- Final seasoning and serve: Finish with freshly cracked black pepper, adjust salt as needed, toss together, and serve immediately while hot to enjoy the perfect blend of flavors and textures.
Notes
- Thinly slicing steak helps it cook quickly and remain tender.
- Use medium-high heat for searing to avoid steaming the meat.
- Cook steak in batches if necessary to prevent overcrowding and ensure proper browning.
- Pre-mix sauce ingredients to speed up cooking.
- Add freshly cracked black pepper last to keep the flavor bright.
