Step 1: Season the chicken - Pat the chicken thighs dry with a paper towel and season both sides with the salt and black pepper. This small step helps build flavor right from the start and gives the chicken a better texture when it hits the pan.
Step 2: Sear the chicken - Heat the oil in a skillet over medium heat. Add the chicken thighs and sear them lightly on both sides until they get a little color. You are not cooking them through here. You are just waking up the flavor and giving the outside a bit of personality.
Step 3: Add chicken to the slow cooker - Transfer the seared chicken thighs into your slow cooker, arranging them in an even layer so they cook evenly and soak up the sauce.
Step 4: Mix the sauce - In a bowl, whisk together the honey, bourbon, soy sauce, ketchup, apple cider vinegar, and garlic powder until smooth. This sauce is the heart of the dish, and it is where all that sweet savory magic comes from.
Step 5: Pour and cook low and slow - Pour the sauce over the chicken thighs, making sure every piece gets coated. Cover and cook on low for 5 to 6 hours until the chicken is tender and the sauce has thickened. Uncover the slow cooker for the last 30 minutes to let the sauce reduce and get glossy.
Step 6: Spoon and serve - Before serving, spoon some of the sauce over the chicken so every bite gets that sticky sweet finish. This is the moment when everyone usually starts sneaking tastes from the pot.
