Step by Step
Preparing the Ingredients
Start by trimming any excess surface fat from the flank steak. Place the steak in the freezer for 10 minutes to firm it slightly, which makes thin slicing easier. Slice against the grain into strips about 0.25 inch thick. Keep the slices uniform so they cook evenly. Set the steak aside at room temperature while you prepare the peppers.
Wash and dry the bell peppers thoroughly. Cut off the tops, remove seeds and membranes, then slice into even strips. Consistent size helps the peppers cook at the same pace, staying tender yet crisp. Mince the garlic and ginger finely so they release aroma quickly without burning.
Cooking the Peppers
Heat 1 teaspoon of the vegetable oil over medium high heat in a large pan. Once the oil shimmers, add the red and green peppers in a single layer. Cook for 3 to 4 minutes, stirring occasionally, until the peppers are just tender with a slight bite. Avoid browning them too much at this stage. Transfer the peppers to a plate and set aside. This step keeps their color bright and texture fresh.
Searing the Steak
Add the remaining oil to the same pan and increase the heat to high. Season the sliced flank steak lightly with salt and pepper. When the pan is hot, add the steak in a single layer. Let it sear undisturbed for about 2 minutes to develop color, then stir and continue cooking for a total of 5 to 6 minutes until lightly browned. Work in batches if needed to avoid crowding, which can cause steaming instead of searing.
Building Flavor
Lower the heat slightly and add the minced garlic and ginger to the steak. Stir constantly for about 30 seconds until fragrant. Garlic burns quickly, so keep it moving and brief. Return the cooked peppers to the pan and toss everything together to combine.
Making the Sauce
In a small bowl, whisk together La Choy Soy Sauce, sugar, water, and cornstarch until smooth. Ensure there are no lumps, as cornstarch needs to be fully dissolved for a glossy finish. Pour the sauce over the steak and peppers, stirring to coat evenly. Bring the mixture to a gentle simmer. Cook for 2 to 3 minutes until the sauce thickens and clings to the beef and vegetables. Taste and adjust seasoning if needed. Serve immediately for best texture.
Storage
Short Term Storage
Allow the Pepper Steak Stir-Fry to cool slightly before storing. Transfer to an airtight container and refrigerate for up to 3 days. Keep rice or noodles separate to prevent them from absorbing too much sauce.
Reheating Tips
Reheat gently in a skillet over medium heat with a tablespoon of water to loosen the sauce. Stir frequently to warm evenly. Microwaving works as well, but use short intervals and stir between to avoid overcooking the steak.
Freezing Notes
Freezing is possible for up to 2 months, though peppers may soften after thawing. Cool completely, portion into freezer safe containers, and label with the date. Thaw overnight in the refrigerator before reheating.
Variations and Substitutions
Protein Options
Swap flank steak with sirloin, top round, or flat iron steak sliced thin. For a lighter option, use thin sliced chicken breast or chicken thigh meat. Adjust cooking time accordingly.
Sauce Twists
Use Bragg Liquid Aminos or Coconut Secret Coconut Aminos in the same quantity for a slightly different savory profile. Add a teaspoon of rice vinegar for brightness or a pinch of crushed red pepper for heat.
Vegetable Add Ins
Broccoli florets, snap peas, or sliced onions work well. Add firm vegetables first and quicker cooking ones later to maintain texture.
Tips and Tricks
Slicing for Tenderness
Always slice against the grain. Look for the direction of muscle fibers and cut perpendicular. This shortens the fibers and makes each bite tender.
Heat Management
Preheat the pan thoroughly before adding the steak. High heat is essential for browning. If the pan cools too much, pause and reheat between batches.
Sauce Control
If the sauce thickens too much, add a splash of water and stir. If it is too thin, simmer for another minute. Cornstarch thickens more as it cools, so aim for a slightly loose sauce in the pan.
Timing Matters
Have all ingredients prepped before cooking begins. Stir frying moves fast, and preparation prevents overcooking.
Notes
Ingredient Quality
Choose fresh, firm bell peppers with glossy skin. For beef, look for good marbling without excessive fat. Fresh ginger adds brighter flavor than powdered.
Flavor Balance
This Pepper Steak Stir-Fry balances salty, sweet, and savory notes. Adjust sugar to taste, especially if serving with a sweet side. Pepper adds warmth without overpowering the dish.
Serving Temperature
Serve immediately after cooking for the best texture. The steak remains tender and the peppers retain their snap.
Serving Suggestions
Serve Pepper Steak Stir-Fry over steamed jasmine rice, brown rice, or rice noodles. Garnish with sliced green onions or toasted sesame seeds if desired. A simple cucumber salad on the side adds freshness.
