Expert Tips

- Veggie Variations: Feel free to mix and match bell pepper colors! Using a variety adds visual appeal and enhances flavor complexity in your Pepper Steak with Bell Peppers and Onion.
- Don’t Overcook Garlic: When adding minced garlic, keep an eye on it! Cooking too long can make it bitter. Just one minute is perfect to release its aroma.
- Thickening Tips: If using cornstarch, mix it with cold water before adding to the pan. This prevents clumps and ensures a smooth sauce throughout your dish.
- Season Gradually: Start with less salt and black pepper, tasting as you go. It’s easier to add than to take away, ensuring your Pepper Steak with Bell Peppers and Onion isn’t over-seasoned.
