Creating Decadent French Chicken with Creamy Mustard-White Wine Sauce is simple if you follow these steps closely:

1. Prepare Chicken: Season the chicken breasts with salt and pepper on both sides.
2. Heat Oil: In a large skillet, heat the olive oil over medium-high heat until shimmering.
3. Cook Chicken: Add the chicken breasts to the skillet and sear for about 5-7 minutes on each side, or until golden brown and cooked through. Remove from the skillet and set aside.
4. Sauté Aromatics: In the same skillet, add the butter. Once melted, add the chopped shallots and minced garlic, cooking for about 2-3 minutes until softened and fragrant.
5. Deglaze with Wine: Pour in the white wine, scraping the bottom of the skillet to release any browned bits. Allow it to simmer for about 5 minutes, reducing slightly.
6. Add Cream and Mustard: Stir in the heavy cream and Dijon mustard, mixing until fully incorporated. Let the sauce simmer for another 5 minutes until it thickens.
7. Season Sauce: Add the fresh thyme and adjust the seasoning with salt and pepper to taste.
8. Return Chicken: Place the cooked chicken breasts back into the skillet, spooning the sauce over them. Cook for an additional 2-3 minutes to heat through.
9. Garnish: Once plated, sprinkle the chicken with fresh parsley for a burst of color and flavor.
