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 create a thin, even coating.
02 - In a large skillet over medium-high heat, melt 1 tablespoon of unsalted butter. Add the seasoned chicken breasts and sear for 3 to 4 minutes per side until a golden crust forms. Transfer the chicken to a plate and set aside.
03 - Reduce the heat to medium and add the remaining 1 tablespoon of butter to the same skillet. Add the minced garlic and sauté for about 1 minute until fragrant, being careful not to let it brown.
04 - Stir in the honey, soy sauce, and Dijon mustard. 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 reduce slightly for 1 to 2 minutes.
05 - Return the seared chicken breasts to the skillet, turning to coat them evenly in the sauce. Cover with a lid and cook for 10 to 12 minutes, or until the internal temperature of the thickest part reaches 165°F (74°C).
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 golden. Remove from heat and set aside.
07 - Transfer each chicken breast to a serving plate and spoon the pan sauce generously over the top. Scatter the toasted pecans over each piece and finish with a sprinkle of fresh chopped parsley if desired. Serve immediately.
