Step 1: Season the Chicken - Pat the chicken thighs dry if they seem wet, then season both sides with the salt, black pepper, and garlic powder. I like to do this right on a plate or small sheet pan so I can see that every piece gets a little seasoning. This first layer matters because the glaze flavors the outside, but the seasoning helps the chicken itself taste good all the way through.
Step 2: Wrap the Chicken with Bacon - Wrap each chicken thigh with one slice of bacon, then place it in the slow cooker with the end of the bacon tucked underneath. That helps the bacon stay in place while everything cooks. You do not need to make it look fancy. Just wrap it snugly enough that the bacon hugs the chicken, then set each piece in a single layer if your slow cooker allows it.
Step 3: Whisk the Maple Glaze - In a bowl, whisk together the maple syrup, brown sugar, Dijon mustard, Worcestershire sauce, apple cider vinegar, onion powder, and smoked paprika. The sauce should look dark, glossy, and a little thick even before cooking. Give it a good whisk so the mustard blends smoothly into the maple syrup instead of sitting in little streaks. That way every piece of chicken gets the same sweet savory coating.
Step 4: Pour the Sauce Over the Chicken - Pour the maple mixture evenly over the bacon wrapped chicken in the slow cooker. Try to drizzle a little over each piece so the tops get coated right away. Some sauce will run down into the bottom, and that is exactly what you want. As the chicken cooks, the juices mingle with the maple mixture and create the base for that sticky glaze at the end.
Step 5: Slow Cook Until Tender - Cover the slow cooker and cook on low for 5 to 6 hours or on high for 3 to 4 hours, until the chicken is tender and fully cooked. Low is my favorite when I have the time because the chicken becomes especially soft and juicy. Try not to lift the lid too often, even though the smell will tempt you. Every peek lets heat escape, and the slow cooker needs that steady warmth to do its job.
Step 6: Rest the Chicken - Carefully remove the chicken from the slow cooker and set it on a plate. Cover it loosely with foil while you thicken the sauce. The chicken will be tender, so use tongs and take your time. This little rest keeps the chicken warm and gives you room to turn the sauce into a glaze without breaking the bacon wrapped pieces apart.
Step 7: Make the Cornstarch Slurry - In a small bowl, whisk together the cornstarch and water until completely smooth. This is called a slurry, and it keeps the cornstarch from clumping when it hits the hot sauce. It only takes a few seconds, but it makes a big difference. You want it thin and milky looking with no dry bits hiding at the bottom of the bowl.
Step 8: Thicken the Maple Sauce - Stir the cornstarch slurry into the sauce left in the slow cooker. Turn the slow cooker to high and cook uncovered for 10 to 15 minutes, stirring every few minutes, until the sauce turns glossy and thick enough to coat a spoon. This is where the dish really comes together. The sauce changes from thin and brothy to sticky and rich, and you will know it is ready when it leaves a shiny layer on the spoon.
Step 9: Coat the Chicken in Glaze - Return the chicken to the slow cooker and gently turn each piece in the thickened maple glaze. Go slowly here because the chicken will be tender. Spoon extra glaze over the tops so the bacon gets coated too. This final coating gives you that beautiful sticky finish and makes every bite taste like maple, smoke, and savory chicken.
Step 10: Garnish and Serve Warm - Spoon a little more glaze over the chicken right before serving, then sprinkle with chopped parsley. The parsley is not just for looks. It adds a fresh little lift against the rich bacon and maple sauce. Serve the chicken warm with something that can catch the extra glaze, because leaving that sauce behind would be a real shame.
