Preheat oven to 375F.
In a cast iron or other oven safe skillet, heat olive oil.
Butterfly the chicken breasts and salt and pepper both sides.
Sear the chicken breasts over high heat 3 minutes on each side until browning, then remove to a plate.
Pour chicken stock into pan and deglaze, scraping the browned chicken from the bottom of the pan for a minute.
Add the chopped onion and reduce the liquid for 2 minutes.
Add the minced garlic until aromatic.
Add the white wine, and reduce for 2 minutes.
Turn the heat down to low, and add butter and flour. Stir for 3 minutes over low heat.
Turn off the heat and add mustard, dill, lemon, salt and pepper and stir.
Add the cream and stir, off heat.
Add the chicken back and coat with sauce.
Place the pan in the preheated oven for 13 minutes.
When removing from oven, it's advisable to check the temp of the thickest part of the chicken to be sure it is >165F. If not, return thicker pieces to the oven.
Once chicken is fully cooked, garnish with fresh parsley.
Serve immediately, or keep warm in 200F oven.
This looks so amazing! I feel like putting it over some angel hair pasta will be so good!
