Preheat the oven to 375°F.
In a bowl, whisk together the olive oil, lemon juice, Dijon mustard, honey, CTH seasoning, onion powder, rosemary, and garlic powder.
Add the chicken, quartered potatoes or sweet potatoes, and your green vegetable to a baking dish. Pour the marinade over everything.
Place 6 slices of butter over the top.
Bake covered for 30 minutes.
Bake uncovered for another 20 minutes until the chicken is cooked through and the potatoes are tender.
Remove the cooking juices from the dish and whisk in 1 tablespoon cornstarch until the sauce thickens. Pour back over the chicken before serving.
