Can you still cook perogies if they thawed out when frozen?

Yes, you can still cook perogies if they thawed out while frozen, as long as they were thawed safely in the refrigerator and not left at room temperature for too long. Simply cook them according to your preferred method—boiling, frying, or baking. However, if they were thawed at room temperature for an extended period, it's best to discard them to avoid food safety risks. Always ensure they are heated thoroughly before serving.
