Crockpot Apple Cider Chicken Thighs

This recipe is taken directly from a new cookbook I got, "Make Ahead Paleo", by Tammy Credicott.  I've tried a few recipes out of it, but this is the best one so far.  I tried my own version of this recipe a few weeks before I saw this one, but this one nails it.

3 lbs boneless, skinless chicken thighs
Salt and pepper to taste
1 shallot, minced
3 cloves garlic, minced
1 apple (I used a Honeycrisp), peeled, cored and sliced into 1/4 inch pieces
1 bay leaf
1 cup apple cider
1/2 cup apple cider vinegar
1/4 cup olive oil
1 tsp dried thyme (or 2 tsp fresh)

Place chicken in slow cooker and season with S&P.  Sprinkle shallot, garlic, sliced apple and bay leaf over chicken.  Mix cider, vinegar, oil and thyme together and pour over chicken.  Cook on low 6 hours.  Spoon the sauce over the chicken to serve (I ladled some of it into a small saucepan and simmered over medium heat until reduced by about half, which thickened the sauce a bit and concentrated the flavors).
