Prepare the chicken thighs by trimming any excess fat.
In a bowl, whisk together chicken broth, lemon juice, soy sauce, honey, garlic, ginger, and cornstarch.
Place the chicken thighs in the crockpot and pour the sauce over them.
Cook on low for 6-8 hours or on high for 3-4 hours until the chicken is tender.
Once cooked, remove the chicken and set it aside. Turn the crockpot to high and let the sauce thicken for about 15 minutes.
Shred or slice the chicken as desired, then return it to the crockpot.
Serve the lemon chicken warm, garnished with green onions.
