Creating French Mustard Chicken is a breeze when you follow these simple steps:

1. Prepare Chicken: Season the chicken breasts with salt, pepper, garlic powder, and dried thyme on both sides.
2. Heat Oil: In a large skillet over medium heat, add the olive oil. Allow it to heat for about 1 minute.
3. Sear Chicken: Add the seasoned chicken breasts to the skillet. Cook for 5-7 minutes on each side until golden brown and cooked through. Remove the chicken from the skillet and set aside.
4. Create Sauce: In the same skillet, lower the heat. Add the Dijon mustard and stir for about 1 minute to release the flavors.
5. Add Cream: Gradually pour in the heavy cream, stirring continuously. Allow the sauce to simmer for 3-5 minutes until it thickens slightly.
6. Combine: Return the chicken to the skillet, coating it with the creamy mustard sauce. Cook for an additional 2-3 minutes to heat through.
7. Garnish: Remove from heat and garnish with freshly chopped parsley before serving.

These straightforward steps will guide you to create a delightful meal that will tantalize your taste buds and impress your guests.
