In a large bowl, combine soy sauce, honey, ketchup, garlic, basil, oregano, red pepper flakes and pepper.
Place chicken thighs, potatoes, carrots and soy sauce mixture into a 6-qt slow cooker. Cover and cook on low heat for 7-8 hours or high for 3-4 hours, basting every hour. Add green beans during the last 30 minutes of cooking time.
Preheat oven to broil. Place chicken thighs onto a baking sheet, skin side up, and broil until crisp, about 3-4 minutes.
Serve chicken immediately with potatoes, carrots and green beans, garnished with parsley, if desired.
Notes
Use the right size crockpot. A 6-qt slow cooker is ideal for this recipe. If the slow cooker is too small, the chicken may not cook evenly. If the slow cooker is too large, the liquid may cook down too quickly, causing the chicken and veggies to burn.
Bone-in chicken will have more flavor. While boneless, skinless chicken thighs or breasts can be used, bone-in will be juicier and have extra flavor.
Use reduced sodium soy sauce. Reduced sodium has less sodium and less salt without compromising flavor.
Add an optional cornstarch slurry. For a thicker sauce, stir in a cornstarch slurry (1 tablespoon cornstarch + 1 tablespoon cooking liquid) with the green beans.
Helpful swaps. Swap out the baby red potatoes for sweet potatoes, or broccoli for the green beans.
Make it crispy. Broil the chicken, skin side up, for a few minutes on the top rack, about 6 inches from the broiler, for that caramelized glaze on the skin. Watch closely though as the skin can burn very quickly!
Serve with your favorite grains. White rice, brown rice, cauliflower rice, quinoa or farro are all great options to sop up the sauce.
Reheat in the oven. Leftover chicken can be rubbery when reheated. For best results with leftovers, reheat in the oven at 350°F, covered in aluminum foil until warmed through.
