Smothered in sweet BBQ sauce, these easy Slow Cooker BBQ Chicken Thighs are slow-cooked until they are fall off the bone tender. You get juicy BBQ chicken thighs without the grill!
Whisk together the BBQ sauce, apple cider vinegar, brown sugar, garlic powder, and Worcestershire sauce in a bowl.
In a large skillet over medium-high heat, heat the olive oil. Add the chicken thighs, skin side down, and cook until golden. Flip over and cook for a few minutes more.
Carefully transfer the browned chicken thighs to the bottom of a slow cooker. Pour the sauce over the chicken thighs, covering them fully.
Cook for 3 hours on high or low for 4 to 6 hours. Once the chicken has reached an internal temperature of 165°F, remove them from the slow cooker.
Carefully pour the sauce into a small saucepan. Cook the sauce over medium heat, stirring frequently. Bring to a boil and reduce the heat to a simmer. While the sauce simmers, whisk together the cornstarch and water until thickened. Stir the thickened cornstarch mixture into the sauce. Cook the sauce until thickened or desired thickness has been achieved. Remove the pan from the heat.
Pour the thickened sauce over the chicken thighs. Serve immediately.
