Step-by-Step Instructions
Preparation Phase (5 minutes)
- Slice your flank steak against the grain into thin strips (about 1/4 inch thick). Pro tip: For easier slicing, place the steak in the freezer for 15-20 minutes before cutting.
- Cut bell peppers and onions into strips of similar size for even cooking.
- In a small bowl, whisk together all sauce ingredients until the cornstarch is fully dissolved.
Cooking Phase (10 minutes)
- Heat your wok or large skillet over high heat until it’s smoking slightly. Add 1 tablespoon of oil and swirl to coat.
- Add the sliced beef in a single layer (work in batches if needed). Let it sear for 1 minute without moving, then stir-fry for another minute until browned but not fully cooked. Remove to a plate.
- Add remaining oil to the wok. Add onions and stir-fry for 1 minute.
- Add bell peppers, garlic, and ginger. Stir-fry for 2 minutes until vegetables are crisp-tender.
- Return beef to the wok. Pour in the sauce mixture.
- Cook, stirring constantly, until the sauce thickens and coats everything evenly (about 2 minutes).
Pro Tips for Perfect Pepper Steak
- Room Temperature Meat: Remove your steak from the refrigerator 30 minutes before cooking for more even cooking.
- Hot Wok: Your wok should be hot enough that a drop of water instantly evaporates.
- Don’t Overcrowd: Cook in batches if necessary to maintain high heat and achieve proper searing.
- Slice Uniformly: Keep your meat and vegetable slices consistent in size for even cooking.
Common Mistakes to Avoid
- Using the wrong cut of beef: Stick to flank steak, sirloin, or tri-tip for the best results.
- Not slicing against the grain: This results in chewy, tough meat.
- Overcooking the vegetables: They should remain crisp-tender.
- Using low heat: High heat is crucial for proper stir-frying.
Storage and Reheating
Store leftover pepper steak in an airtight container in the refrigerator for up to 3 days. To reheat, warm in a skillet over medium heat until just heated through, or microwave in 30-second intervals. Add a splash of water if the sauce has thickened too much.
Serving Suggestions
- Steamed jasmine rice
- Brown rice for a healthier option
- Cauliflower rice for a low-carb alternative

Recipe Variations
- Spicy Version: Add sliced fresh chilies or red pepper flakes
- Vegetable-Heavy: Double the peppers and add mushrooms
- Low-Sodium: Use coconut aminos instead of soy sauce
- Keto-Friendly: Serve over cauliflower rice and use xanthan gum instead of cornstarch
Frequently Asked Questions
Q: Can I use a different cut of beef?
A: Yes, sirloin or tri-tip work well as alternatives to flank steak. Just make sure to slice thinly against the grain.
Q: How can I make this recipe gluten-free?
A: Use tamari instead of soy sauce and ensure your oyster sauce is gluten-free certified.
Q: Can I prep this ahead of time?
A: Yes! Slice the meat and vegetables up to 24 hours in advance and store separately in the refrigerator. Mix the sauce up to 2 hours before cooking.
Q: Why isn’t my sauce thickening?
A: Make sure your cornstarch is fully dissolved in the sauce mixture before adding it to the wok, and let it come to a full simmer to activate the thickening properties.
Q: Can I freeze this dish?
A: While possible, I don’t recommend freezing as the vegetables can become mushy when thawed. If you must freeze, store for up to 2 months and thaw overnight in the refrigerator.
Shopping Tips
When shopping for this recipe, here are some key things to look for:
- Choose bright, firm bell peppers with smooth skin
- Look for flank steak with good marbling
- Check that your soy sauce and oyster sauce aren’t expired
- Fresh ginger should be firm and fragrant
- Select onions that are heavy for their size with no soft spots
Remember, quality ingredients make a significant difference in the final dish. I always say it’s worth spending a little extra on good quality meat and fresh vegetables for the best results.
Kitchen Safety Notes
- Always wash hands thoroughly before and after handling raw meat
- Use separate cutting boards for meat and vegetables
- Keep a fire extinguisher nearby when cooking with high heat
- Be careful of hot oil splatter when stir-frying
- Ensure meat reaches a safe internal temperature of 145°F (63°C)
