Preheat oven to 375F. Pat chicken dry with paper towels and season all over with salt and pepper. Meanwhile, heat oil and butter in a large oven-safe skillet over medium-high until shimmery.
Add chicken to pan and sear 2-3 minutes on both sides, flipping once until chicken is golden brown (chicken will not be fully cooked through yet) Remove chicken from pan and set aside.
Drain all but 1 tablespoon fat from pan. Over medium heat, add garlic to pan and saute in pan drippings until just fragrant, about 1 minute.
Add chipotle, reserved adobo sauce, honey, sugar, hot sauce, and chicken broth to pan and bring to a low simmer over medium heat until slightly thickened. Season sauce with salt and pepper to taste.
Remove pan from heat and nestle chicken thighs back into pan, spooning more of the sauce over top. Bake chicken at 375F 15-20 minutes until chicken registers 165F. Sprinkle green onions on top.
Serve chicken hot with more of the sauce spooned on top over hot rice if desired. Enjoy!
