Pat the chicken breasts dry with paper towels and season both sides with 0.5 teaspoon of salt and 0.25 teaspoon of black pepper.
In a shallow bowl, combine the panko breadcrumbs, parsley, and thyme. Mix thoroughly.
Press the presentation side (top) of each chicken breast firmly into the herb-breadcrumb mixture to ensure a thick, even coating.
Heat the olive oil in a large stainless steel or cast iron skillet over medium-high heat until shimmering.
Place the chicken breasts in the skillet, herb-side down. Sear for 5 to 6 minutes without moving until a golden-brown crust forms.
Carefully flip the chicken and continue cooking for 6 to 8 minutes, or until the internal temperature reaches 165°F (74°C).
Transfer the chicken to a warm plate and tent loosely with aluminum foil to rest.
Reduce the skillet heat to medium. Add the butter and minced shallots; sauté for 2 minutes until translucent.
Pour in the white wine to deglaze the pan, scraping the bottom with a wooden spoon to incorporate the fond. Reduce the liquid by half.
Whisk in the heavy cream and Dijon mustard. Simmer for 3 to 4 minutes until the sauce coats the back of a spoon.
Stir in the lemon juice and the remaining salt and pepper. Adjust seasoning to taste.
Serve the chicken breasts topped with a generous portion of the creamy Dijon sauce.
