Mix all the ingredients together except the chicken, chicken broth, and garlic. Pour the chicken broth into a oven safe corning pot, then add your garlic cloves, and chicken thighs. Pour your sauce over the chicken thighs. Bake in the oven at 350F for 2 to 3 hours, covered.
Once the chicken appears cooked, if you have a convection setting on your oven switch it on near the end of the cooking process.Remove the cover and then cook the chicken a little longer.
This will allow the chicken to brown up and caramelize. If the sauce seems soupy, you can bake the chicken a bit longer, near the end of the cooking process mind the chicken thighs and make sure they don't burn.
I flipped them over in the pot so they browned evenly.
