Season chicken thighs with salt and pepper.
Heat the olive oil in a large skillet over medium high heat. Working in batches if needed, add the chicken skin side down to the pan. Sauté until the skin is browned, about 5 – 7 minutes. Remove chicken from pan and set aside.
Add the fennel to the pan and sauté until browned on all sides, about five minutes. Add garlic and sauté until fragrant, about 30 seconds to one minute.
Add the chicken broth and the tomato paste to the pan. Stir tomato paste is completely dissolved. Add the tomatoes and and herbs cook for 2 to 3 minutes. Season sauce with salt and pepper.
Spread tomato sauce into the bottom of a 9 x 13 x 2-inch baking dish. Nestle the chicken thighs in the sauce. Bake for 40-45 minutes or until the meat’s internal temperature reaches 170 degrees. Allow chicken to rest for 10-15 minutes before serving.
Serve with tomato sauce drizzled over the top.
