In a bowl or mason jar, whisk together the olive oil, lemon juice, lemon zest, garlic, herbs, salt, pepper, and Dijon mustard if using.
Place the chicken in a glass container or reusable storage bag and pour the marinade over it. If your mixing bowl is big enough you can just put the chicken in there.
Cover and refrigerate for at least 2 hours or up to 24 hours.
Remove the chicken from the marinade and discard any remaining lemon chicken marinade.
Grill, bake, or pan-sear until the chicken reaches an internal temperature of 165°F.
Notes
For extra lemon flavor, serve with fresh lemon wedges and a sprinkle of chopped parsley.
This recipe makes enough for 2-3 pounds of chicken or 8-12 servings.
