Preheat oven to 275F and spray a baking dish with cooking spray.
Melt the butter in a small saucepan and add the brown sugar, honey, soy sauce, garlic, black pepper, bourbon, and lemon juice. Whisk until well blended. Bring the glaze to a boil over medium heat and stir often. Reduce the heat to low and simmer the mixture until it thickens and reduces, approximately 3-5 minutes. Stir the glaze often.
Place the salmon, skin-side-down, on the prepared dish. Brush the salmon with the prepared glaze. Cover the salmon with pecans and press the pecans firmly into the salmon. Cook for 10 minutes at 275F.
Drizzle additional glaze over the salmon and cook another 5-10 minutes or until a meat thermometer inserted in the thickest part, registers 120F.
Remove the salmon from the oven and turn the oven to broil.
Drizzle the salmon with glaze and place it in the oven. Broil 1-2 minutes, just until the pecans turn golden. **Watch the salmon while it broils – the pecans can burn quickly. The final internal temperature should be 125F-130F. Remove the salmon from the oven and allow it to cool, in the dish, 5-10 minutes before serving.
