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 to ensure an even, thin coating.
02 - In a large skillet over medium-high heat, melt 1 tablespoon of unsalted butter. Once the butter is foaming, add the seasoned chicken breasts and sear for 3 to 4 minutes per side until a golden-brown crust develops. Transfer the chicken to a plate and set aside.
03 - Reduce the heat to medium. Add the remaining 1 tablespoon of butter to the same skillet, then add the minced garlic. Sauté for about 1 minute, stirring constantly, until fragrant and lightly golden.
04 - Stir in the honey, soy sauce, and Dijon mustard into the garlic butter. Bring the mixture to a gentle simmer, using a wooden spoon to scrape up any browned bits from the bottom of the skillet. Let the sauce simmer for 1 to 2 minutes until it begins to thicken slightly.
05 - Return the seared chicken breasts to the skillet, spooning the sauce over each piece to coat evenly. Cover the skillet with a lid and cook for 10 to 12 minutes, basting occasionally, until the chicken is cooked through and reaches an internal temperature of 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 breasts to serving plates and generously spoon the pan sauce over each piece. Top with the toasted pecans and garnish with freshly chopped parsley if desired. Serve immediately while hot.
