Prepare Marinade: In a food processor, combine fresh cranberries, brown sugar, olive oil, honey, balsamic vinegar, minced garlic, orange juice, zest, sea salt, and black pepper. Blend until smooth.

Marinate Chicken: Place the chicken thighs in a large zip-lock bag, pour the marinade over chicken, seal, and refrigerate for at least 2 hours.

Preheat the Oven: Preheat your oven to 375°F (190°C). Prepare an 8x8 inch baking pan by greasing it lightly.

Bake Chicken: Transfer marinated chicken to the baking pan, pour any remaining marinade over, and bake for 25-30 minutes until cooked.

Broil for Crispiness: Brush chicken skin with a mixture of honey and olive oil, then broil for 2-3 minutes until skin is crispy.

Serve and Garnish: Let the chicken rest for about 10 minutes, then garnish with orange zest and cranberries before serving.
