You’re going to need about 10-12 ounces of plain Greek yogurt–2 5.3-ounce containers will do the job, but if you’re trying to use up that 32-ouncer you bought on sale, you can do 12 and it will be good either way. I’ve also used half plain Greek and half regular and it was delicious. It’s hard to go wrong here.
You can use either chicken breasts or thighs. Thighs are moist and flavorful and one of my favorite meats to grill, but breasts are also fantastic; I’ve done it both ways and highly recommend either one. Or both. You could be that person (I’m actually not exactly sure what “that person” would be, just the kind of person who would serve both chicken breasts and thighs. Is that a thing? It is now.) Trim your boneless skinless chicken meat of choice of excess fat and place it in a Ziploc bag.
For the marinade, you’ll need kosher salt, black pepper, red wine vinegar, lots of minced garlic, chopped green onions, and Greek seasoning. I have been able to find Greek seasoning with the McCormick spices at my Kroger–not the regular McCormick spices, but kind of the fancy-schmancy spices. But if you can’t find it, just mix equal parts dry mint, oregano, and basil. You’ll also need the zest of a small lemon. If you’re like me and went grocery shopping on a Saturday with three children and were on the verge of harming yourself or others and/or tears by the time you left, and you also happened to leave without lemons, about 1/2 teaspoon of True Lemon will do the trick nicely.
Add the seasonings to the yogurt…
and give it a good whisk. Drizzle the marinade over the chicken and let it chill out for about 6-8 hours (4 will work in a pinch, especially if you’re using thighs.)
When you’re ready to grill, preheat the grill over medium for 10-15 minutes, then grill the chicken breasts for 7 minutes per side or 4-5 for thighs. Remove from heat and allow to stand for about 3-5 minutes. Serve immediately. I just served this with dipping veggies on the side (like cherry tomatoes, sliced cucumbers, etc.) and Greek-ish garlic bread (very much like this recipe.)
