Season room temperature, patted dry chicken breasts with chicken seasoning mix and rub it into both sides.
In a bowl, add the dredging ingredients and whisk together to combine. Coat the chicken breasts in the seasoned flour on all sides, shaking off any excess, and set aside.
In a pan with oil, add the chicken breast and cook for 5 minutes on each side over medium-high heat until browned; remove from the pan once browned.
If thereβs too much oil in the pan, remove some, leaving about 2 tablespoons. Add in butter, onion, garlic, cracked black pepper, and 1/4 cup of the reserved seasoned flour (or just all-purpose flour), whisking continuously for 3β5 minutes.
Add water and bouillon and continue whisking for another 3β5 minutes until slightly thickened. Stir in heavy cream and return the chicken to the pan along with any juices. Bring to a simmer.
Once simmering, transfer the pan to the oven and cook for 20β25 minutes. Garnish with parsley and serve with mashed potatoes or rice.
