It was one of those evenings when I was staring at chicken thighs in my refrigerator and wondering how to transform them into something special. With a bundle of fresh tarragon from my herb garden threatening to wilt, I remembered my grandmother’s popover technique. What began as a creative way to stretch a few chicken pieces turned into one of our family’s most requested meals.

Hi, may I substitute rotisserie chicken for this dish? It looks delicious! Thank you.
Yes, I think that would work well.
Loved this!!! Added 1/2 tea more of tarragon and substituted table cream for the milk. This recipe will be difficult to keep out of our rotation. Thanks Steph.
I love chicken served like this.
