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

1. Prepare the Chicken: Season the chicken breasts with salt and pepper on both sides.
2. Heat the Oil: In a large skillet, heat the olive oil over medium-high heat until hot.
3. Cook the Chicken: Add the chicken breasts to the skillet and cook for 6-7 minutes on each side until golden and cooked through. Remove the chicken from the skillet and set aside.
4. Sauté the Garlic: In the same skillet, add the minced garlic and sauté for about 30 seconds until fragrant.
5. Deglaze with Wine: Pour the white wine into the skillet, scraping the bottom to release any browned bits. Let it simmer for 2-3 minutes to reduce slightly.
6. Add Cream and Mustard: Stir in the heavy cream and Dijon mustard, mixing until well combined.
7. Season the Sauce: Add the thyme, and season with salt and pepper to taste. Let the sauce simmer for an additional 3-4 minutes, allowing it to thicken.
8. Return Chicken to the Skillet: Place the cooked chicken breasts back into the skillet, spooning the sauce over them. Cook for another minute to warm through.
9. Garnish and Serve: Remove from heat and garnish with chopped parsley if desired.
