Cover and refrigerate for at least 1 hour, or up to 24 hours.
Tzatziki
To make the tzatziki, squeeze the grated cucumber with a paper towel or kitchen cloth. Squeeze, removing all water.
⅓ cucumber
Add all of your tzatziki ingredients and mix to combine.
1 cup plain yogurt, 3 garlic cloves, 1 teaspoon dried oregano, 3 tablespoons fresh dill, ¼ cup fresh lemon juice, 1 teaspoon kosher salt, 1 teaspoon ground black pepper
Cover and refrigerate until ready to serve.
When ready to cook, add your skewers to a bowl of water, allowing to soak for 10-15 minutes.
Add your marinated chicken pieces to your skewers, about 4-5 pieces each skewer.
Cook the chicken skewers in either the oven or on the grill.
Oven
Preheat the oven to 400F and prepare a baking sheet with aluminum foil and olive oil.
Place the skewers on the prepared baking sheet.
Bake for 12-15 minutes until chicken is no longer pink and has reached 165F internal temperature.
Grill
Preheat your indoor or outdoor grill to medium high heat. Grease the grates.
Place on your hot grill, and cook for 5-6 minutes on each side until the chicken has reached an internal temperature of 165F. Add more oil in between batches.
Serve with sauce and desired sides and toppings.
Notes
Chicken: Feel free to use boneless, skinless chicken thighs if you prefer.
Yogurt: I just use plain, nonfat yogurt in this recipe. You could use plain whole milk yogurt if you prefer.
Lemon juice: Fresh lemon juice will give you the best flavor. Bottled lemon juice can have an off taste.
Dill: You can substitute 1 teaspoon of dried dill in place of the fresh dill.
