How to Make It
Preheat oven to 350°.
Heat a large ovenproof skillet over medium-high heat. Add oil to pan; swirl to coat. Sprinkle chicken evenly with 1/2 teaspoon salt and pepper. Add chicken to pan, skin side down; sauté 4 minutes or until browned. Turn chicken over. Place pan in oven; bake at 350° for 40 minutes or until a thermometer inserted in thickest portion registers 160°. Remove chicken from pan, and let stand for 10 minutes.
Return skillet to medium-high heat. Add wine to pan; bring to a boil. Cook 1 minute or until reduced to 2 tablespoons, scraping pan to loosen browned bits. Stir in mustard. Combine cream and flour, stirring until smooth. Add cream mixture to pan; bring to a boil. Cook until slightly thick, stirring constantly with a whisk. Stir in remaining 1/8 teaspoon salt. Serve with chicken.
