Common Questions and Answers
Q: Can I use a different cut of beef?
Yes! While sirloin is my go-to choice, you can use chuck roast, flank steak, or even round steak. Just remember that tougher cuts may need longer cooking times.
Q: Why is my sauce too thin?
The most common reason is not using enough cornstarch or not letting it cook long enough after adding the slurry. Mix 1 additional tablespoon of cornstarch with cold water and add it to the pot.
Q: Can I add other vegetables?
Absolutely! Mushrooms, snow peas, or baby corn make excellent additions. Add firmer vegetables at the beginning and more delicate ones in the last hour of cooking.
Q: My peppers got too soft. What went wrong?
This usually happens when the peppers are cut too small or cooked too long. Try cutting them into larger pieces or adding them during the last 2 hours of cooking.
Q: Is this recipe freezer-friendly?
Yes! The cooked pepper steak freezes well for up to 3 months. Just be aware that the peppers might be softer when reheated.
