½cupchicken broth
1cupheavy cream
1teaspoonDijon mustard
½teaspoon salt
¼teaspoonblack peppercracked or a pinch of ground black pepper
2-3tablespoonsParmesan cheese - freshly grated see note
Instructions
Preheat oven to 400 degrees.
Season chicken generously with salt and pepper. Sprinkle all over with Herbs de Provence (or Italian seasoning).
In a large cast iron skillet (or other oven-safe skillet – see note), combine oil and butter over medium-high heat.
Once butter is melted, add the chicken and brown on each side for 1-2 minutes until you get a nice browned color. Transfer to a plate and set aside.
In the same skillet, begin preparing the sauce by adding the butter. Once melted, stir in garlic and mushrooms and sauté 2-3 minutes until mushrooms are browned and garlic is fragrant.
Stir in chicken broth, heavy cream, Dijon mustard, salt, and pepper. Bring to a boil, cook for two minutes at a high boil. Remove from heat.
Return chicken to skillet. Spoon sauce over the chicken, then transfer skillet to the oven to bake for 15-20 minutes until chicken is cooked through and sauce has reduced (it should be thick enough to coat the back of a spoon).
Spoon the mushroom sauce over the chicken and serve.
Notes
Skillet: I prefer a cast-iron skillet to get a really nice browned exterior on the chicken, but a good quality stainless steel pan will work too – simply add an extra teaspoon or two of oil to the pan to keep the chicken from sticking and brown the chicken over medium-low heat.Baking dish option: No oven-safe skillet? No problem. Simply prepare the chicken and mushroom sauce as written in any skillet you have, then transfer to a baking dish/casserole dish before transferring to the oven.Parmesan: Sometimes I add a few tablespoons of freshly grated Parmesan cheese to the sauce, it really takes this sauce over the top! Be sure to grate it yourself from a block – do not use per-shredded Parmesan as it does not melt and incorporate into the sauce as well as freshly-grated Parmesan does and can give your sauce a gritty texture.
