Preheat oven to 350 degrees.

Rinse and pat dry the chicken. Season liberally with salt and pepper.

Heat olive oil in a dutch oven over medium heat. Cook chicken just until browned. Transfer to a plate. In the same pan that you cooked the chicken in, add in the mushrooms cook 3 minutes. Return the chicken to the pan, sprinkle garlic and 1/4 cup of chives over the top. Pour in chicken broth. Cover and bake for 30 minutes. Remove the lid and bake the chicken for additional 10 - 15 minutes or until chicken is cooked through.

Remove chicken from oven. Transfer chicken to a serving platter and cover to keep warm. Place dutch oven back on the stove and turn heat to medium. Bring to a boil. Stir 1 tablespoon of hot pan drippings into the half and half to temper it. Reduce heat and slowly whisk tempered half in half into sauce. Cook 3 – 5 minutes or until sauce thickens slightly. Stir in remaining chives. Spoon sauce over chicken and serve.
