Trim any excess fat from the chicken thighs.
Lightly dredge each thigh in flour, coating both sides.
Sprinkle French Onion seasoning (or BBQ blend) on both sides of the chicken.
Place the chicken thighs in the Crockpot.
Pour in the chicken broth so it just covers the bottom, then place the butter evenly over the chicken.
Cook on high for 4 hours or low for 6-8 hours, until the chicken is tender and cooked through (with an internal temperature of 165°F).
Optional tip: Pair the chicken with creamy mashed potatoes and steamed green beans
