Begin by cubing boneless and skinless chicken breast or thighs into about 1 ½ to 2" pieces. Next, add chicken to a gallon-sized plastic ziplock bag.
Prepare Chicken Souvlaki Marinade
To make the souvlaki marinade, whisk olive oil, freshly squeezed lemon juice, crushed garlic cloves, salt, black pepper, and oregano in a small bowl or a measuring cup.
Pour the marinade over the chicken and let the air out of the bag. Work the marinade into the chicken flesh, then allow to marinate for a few hours.
Thread marinated chicken cubes onto wooden or metal skewers. I had enough chicken for 4 skewers with 9 bite-sized pieces on each.
Grilling Instructions
Preheat grill then brush grates with oil to prevent the chicken skewers from sticking. Baste and grill chicken skewers over medium high heat for 3-½ minutes per side or until the chicken reaches an internal temperature of 165℉.
Notes
Slicing the chicken while it's semi-frozen is easier than when it's fully defrosted.
If using wooden skewers, soak them for at least 30 minutes ahead of time. This will keep the skewers from burning.
Make sure to use warm pita bread, which is more pliable. You can heat the pita bread over the flame on your stove or in a hot cast iron skillet.
To add even more lemony flavor, you can include lemon zest in your marinade.
Store leftovers in an airtight container in the fridge for up to 4 days.
Souvlaki can also be prepared on a grill pan or under a broiler.
To prepare souvlaki in an air fryer, air fry the skewers for 13-15 minutes at 400 degrees, flipping ½ way through.
