Mix together the marinade of oil, balsamic, juice of 1 lemon, thyme, garlic powder, salt, and black pepper. This can be done in a baking dish.
Add the chicken.
Let the chicken marinade 30 minutes, up to 2 hours, rotating at least once in the marinade.
Preheat oven to 350F.
You can bake the chicken in the same dish that you marinaded the chicken in. Leave the marinade in the dish. Bake until the chicken is fully cooked through, approximately 20-30 minutes.
The leftover marinade, after cooking, can be used as a sauce.Most balsamic chicken recipes use sugar or honey to make a thick, sticky sauce. This recipe keeps it lighter by omitting those ingredients. If you DO want a thick sticky sauce, add 2-4 Tablespoons of honey or brown sugar into the marinade.This chicken is also great grilled!
