Make Marinade: In a medium bowl, combine the Greek Marinade Ingredients. Whisk to combine. Set aside.
Prep Chicken: Place chicken on a plate and pat dry with clean paper towel. Season with kosher salt and ground black pepper. Set aside.
Marinate Chicken: Place chicken thighs in a reusable silicone bag or glass container. Pour marinade over top and ensure chicken is fully coated. Cover and let marinate for at least 30 minutes or overnight.
Grill Chicken: Heat grill to medium-high heat (approx. 400 degrees F.). Place a piece of heavy-duty foil over top the grill grates (or your favorite grill mat)* and spray with nonstick cooking spray. Place chicken on top over direct heat and let cook approx. 3-4 minutes per side or until the internal temperature at the thickest part reaches 160 degrees F. Transfer to a plate and let rest 5-10 minutes.
Serve Chicken: Serve chicken with pita bread, crumbled feta cheese, tzatziki sauce, fresh mint or dill, English cucumber, quick pickled onions and fresh lemon slices.
Notes
*Grill Mat or Foil: we tested this without foil on a very clean and well-greased grill grates and we had some major issues with the chicken sticking to the grill grates. We re-tested using foil and it worked perfectly so that is what we recommend to avoid that issue!
Bone-In Chicken Thighs: you can definitely use bone-in chicken thighs if you prefer, simply adjust the cook time accordingly.
Chicken Breast or Chicken Legs: you can use either of these just adjust the cook time accordingly.
Stove Top: cook marinated chicken thighs in a cast iron skillet on medium-high heat for 3-4 minutes a side or until the internal temp of the thickest part reaches 160 degrees F. Transfer to plate and let rest 5-10 minutes.
Storage: store leftover chicken in an airtight container in the refrigerator for up to 3 days.
