Preheat a large skillet over medium-high heat. Season both sides of the chicken with kosher salt and pepper. Add 1 tablespoon oil (I use avocado) and 1 tablespoon butter to the hot pan.
Place chicken in the pan and cook for about 10 min on each side (depending on thickness).
When the chicken is almost cooked through (about 150 degrees internal temp), remove the chicken from the pan, and add pecans, butter, chicken broth, brown sugar, honey, thyme leaves, and parsley. Whisk together over medium heat, then add the chicken back to pan.
Simmer gently for about 5-8 more minutes, spooning the sauce over the chicken. Serve over rice or mashed potatoes when the sauce is bubbly and thickened, and the chicken is cooked through to 165 degrees.
