This chicken dish combines tender breast fillets with Brussels sprouts in a rich, creamy sauce that’s really delicious. The sprouts are quartered and quickly cooked so they keep their bite while picking up a lovely caramelised flavour from the pan.
What makes this recipe special is how quickly the sauce comes together. After cooking the chicken and sprouts, a splash of vermouth deglazes the pan, lifting all those tasty brown bits from the bottom. The cream and wholegrain mustard create a velvety sauce that’s both sophisticated and comforting.
It’s the kind of dinner that feels a bit fancy but doesn’t take ages to prepare. The whole thing comes together in one pan, which means less washing up and more flavour, as each ingredient builds on the last. While it works brilliantly as a weeknight supper, it’s smart enough to serve to guests too.
The sauce is too good to waste, so serving it with mash, couscous or a chunk of crusty bread is a must. And since it’s Christmas Eve, this is a lovely way to use those extra Brussels sprouts you’ve bought for tomorrow’s dinner. A really festive supper that doesn’t take hours to prepare, leaving you more time for wrapping presents and watching Home Alone.
