FAQ

Can I use frozen chicken breasts?

Thaw completely first. Frozen chicken won't brown properly and may result in uneven cooking and food safety concerns.

What if my sauce seems too thick?

Add 1/4 cup chicken broth or white wine to thin. The sauce naturally thickens during slow cooking.

How long will leftovers keep?

Store refrigerated for up to 3 days or freeze for up to 3 months. Reheat gently to prevent sauce separation.
