Questions I Often Get Asked About This Recipe

Can I use a different cut of beef?
Absolutely! While this recipe works best with flank steak or sirloin, you can also use chuck roast or even stew meat for a budget-friendly option.

What if I don’t like mushrooms?
No problem! You can skip the mushrooms or replace them with zucchini, broccoli, or another veggie of your choice.

Can I make this without a crockpot?
Yes! You can cook it on low heat in a Dutch oven or a large pot on the stovetop, but be prepared to stir it occasionally to prevent sticking.

Is this recipe freezer-friendly?
It sure is! Store the cooked pepper steak in an airtight container and freeze it for up to three months. Just reheat on the stovetop or in the microwave when you’re ready to enjoy it.
