While I absolutely love the versatility of tzatziki sauce, which is reason enough to share a homemade recipe, the real reason why we’re chatting about tzatziki sauce is because it’s absolutely essential to serve with my Quick and Easy Marinated Chicken Gyros.
Grate the cucumber. I've found that there's no need to peel the cucumber first, just grate it with the skin. I use a cheese grater to accomplish this step. Once grated, place the grated cucumber in a cheesecloth or towel. Over a sink or bowl, squeeze the water from the cucumber. If you'd like to save the liquid, keep it in the fridge and add it to a smoothie. Set the grated cucumber to the side.
In a medium-size bowl, combine the yogurt, herbs, lemon juice, olive oil, minced garlic, and grated cucumber. Stir to combine. Add the salt and pepper, to taste. Chill the sauce for at least 30 minutes to intensify the flavors. I like to make this sauce in advance and keep it in the fridge for up to a week.
Serve the sauce on chicken, fish, or gyros. Or use the sauce as a dip for toasted pita and veggies.
