01 - Pat the chicken breasts dry with paper towels and season both sides generously with salt and freshly ground black pepper. Lightly dredge each breast in flour, shaking off any excess coating.
02 - Melt 1 tablespoon of unsalted butter in a large skillet over medium-high heat. Place the chicken breasts in the skillet and sear for 3 to 4 minutes per side until a golden crust forms. Transfer the seared chicken to a plate and set aside.
03 - Reduce the heat to medium. Add the remaining 1 tablespoon of butter to the skillet, then add the minced garlic. Sauté for about 1 minute until fragrant and lightly softened.
04 - Stir in the honey, soy sauce, and Dijon mustard. Bring the sauce to a gentle simmer, using a wooden spoon to scrape up any browned bits from the bottom of the skillet for added depth of flavor.
05 - Return the seared chicken breasts to the skillet, turning to coat evenly in the sauce. Cover the skillet and cook for 10 to 12 minutes, or until the internal temperature of the chicken reaches 165°F.
06 - While the chicken finishes cooking, toast the chopped pecans in a separate dry skillet over medium heat for 2 to 3 minutes, stirring constantly, until they become fragrant and lightly browned. Remove from heat and set aside.
07 - Transfer the chicken to serving plates and spoon the remaining pan sauce generously over each piece. Top with the toasted pecans, garnish with fresh chopped parsley if desired, and serve immediately.
