FAQ
Can I use chicken breasts instead of thighs?
Yes, but thighs stay more tender during long cooking. If using breasts, reduce cooking time and check temperature frequently.
What if I don't have red wine?
Substitute with additional chicken broth or white wine. The flavor will be milder but still delicious.
How long will leftovers keep?
Store covered in refrigerator for up to 3 days or freeze for up to 3 months.
