Heat the olive oil and butter in a large skillet over medium high heat. Season the chicken thighs with salt and pepper. Cook the chicken in the pan until browned on one side, about 5 minutes. Turn and brown on the remaining side, about 5 minutes more. Transfer the chicken to a platter.
Carefully pour out the fat from the pan, reserving about 2 tablespoons. Place the onion, celery and carrots in the skillet. Cook until soft, about 3 to 5 minutes. Add the wine, beef broth and tomato paste.
Return the chicken to the pan. Bring to a boil over medium high heat, then reduce the heat to medium low and simmer until the chicken is cooked through, about 20 to 25 minutes.
Stir in the okra and thyme and cook for 3 to 5 minutes more.
Serve with rice or pasta or just on its own.
