These creamy mustard chicken thighs are a go-to in my home when I want a comforting yet impressive main dish. Tender chicken bakes gently in a rich, herby mustard sauce for an easy meal the whole family will love. Every bite balances tangy depth with soothing creaminess and a touch of fresh tarragon.
I remember making this for my family during a chilly autumn evening and watching everyone reach for extra sauce with their potatoes. The scent alone transports me to my grandma’s kitchen in France where tarragon was always growing by the window.
