How to Make Pepper Steak Stir Fry with Onions
Step 1: Prepare Your Ingredients
Start by slicing your steak thinly against the grain to ensure tenderness. Cut the bell peppers into julienne strips and slice the onions into thin wedges. Also, mince fresh garlic and ginger so they’re ready to infuse your stir fry with flavor.
Step 2: Make the Sauce
In a small bowl, whisk together soy sauce, a bit of water or broth, freshly ground black pepper, and optionally a teaspoon of cornstarch to thicken. This sauce will coat every ingredient with savory goodness.
Step 3: Cook the Beef
Heat a wok or large skillet with vegetable or sesame oil over high heat. Quickly stir-fry the beef strips until browned but not fully cooked through, then remove and set aside to keep that perfect tender texture.
Step 4: Sauté Onions and Peppers
In the same pan, add a little more oil if needed and toss in onions and bell peppers. Stir-fry until onions start to turn translucent and peppers soften yet retain their crunch, capturing that amazing texture contrast.
Step 5: Combine and Finish Cooking
Return the beef to the pan along with garlic and ginger. Pour in your pre-mixed sauce and stir everything together, cooking until the sauce thickens and coats each piece of steak and vegetable beautifully. Then, remove from heat and get ready to serve.
Pro Tips for Making Pepper Steak Stir Fry with Onions
- Slice Thin, Cook Fast: Thin slices of steak cook quickly and stay tender—avoid overcrowding the pan to prevent steaming.
- High Heat is Key: Use high heat for a quick sear that locks in juices and keeps veggies crisp.
- Prep Before You Start: Have all ingredients sliced and sauces mixed since stir-frying moves fast.
- Fresh is Best: Use fresh garlic and ginger instead of powders to maximize authentic flavor.
- Don’t Skip the Pepper: Freshly ground black pepper adds an aromatic bite that enhances the dish.
