Grilled Mediterranean Chicken Tacos

Grilled Mediterranean Chicken Tacos might just be the most flavor-packed thing to come off my grill all season. Juicy, herb-marinated chicken meets creamy tzatziki, briny olives, and crumbled feta all wrapped in a warm tortilla. It is a mashup that sounds unexpected but tastes like it was always meant to be.

I first threw this combination together on a weeknight when I had Greek yogurt and fresh dill in the fridge that needed to be used. I marinated the chicken in lemon and oregano the way I always do for a simple Greek-style dinner, then halfway through I thought – why not just make tacos? The result genuinely surprised me. The tzatziki acted like the perfect creamy sauce, the feta added that salty punch, and the whole thing came together faster than I expected. These grilled Mediterranean chicken tacos have been in my regular weeknight rotation ever since because they are fresh, filling, and the kind of dinner that feels special without much effort.

Everything You Need on Your Grocery List

I always use fresh dill and full-fat Greek yogurt for this recipe because both make a noticeable difference in the tzatziki. Pro tip: if you can only find low-fat yogurt, drain it through a cheesecloth for 20 minutes first so it firms up nicely.

For the Chicken:

• 1.5 lbs boneless, skinless chicken breasts (slice thicker pieces in half horizontally for more even grilling)
• 2 tbsp olive oil, extra virgin
• 2 cloves garlic, minced
• 1 tbsp dried oregano
• 1 tsp lemon zest
• 2 tbsp lemon juice, fresh-squeezed preferred
• 1/2 tsp salt
• 1/4 tsp black pepper

For the Tzatziki Sauce:

• 1 cup plain full-fat Greek yogurt
• 1/2 cucumber, grated and squeezed very dry (this step is non-negotiable)
• 2 cloves garlic, minced
• 1 tbsp lemon juice
• 1 tbsp fresh dill, chopped
• Salt to taste

For the Tacos:

• 8 to 10 small flour or corn tortillas (street-size flour tortillas fold the best)
• 1/2 cup crumbled feta cheese
• 1/4 cup Kalamata olives, pitted and sliced
• 1/2 red onion, thinly sliced
• 1 cup cherry tomatoes, halved
• 1/4 cup fresh parsley, chopped

Pro tip: chicken thighs work as a great swap for breasts. They stay juicier on high heat and are more forgiving if you leave them on the grill an extra minute or two.

How to Make Grilled Mediterranean Chicken Tacos Step by Step

I recommend prepping the tzatziki first while the chicken marinates so both are ready at the same time. Reading through all the steps before you start makes the whole process feel smooth.

Step 1: In a large bowl, whisk together the olive oil, minced garlic, oregano, lemon zest, lemon juice, salt, and black pepper. Add the chicken breasts and turn until fully coated. Let marinate for at least 15 minutes at room temperature. For deeper flavor, cover and refrigerate for up to 4 hours. Do not marinate longer than 4 hours or the lemon juice will start to break down the texture of the chicken.

Step 2: While the chicken marinates, make the tzatziki. Grate the cucumber, then transfer it to a clean kitchen towel and wring out as much liquid as possible. This is the most important step for a thick, creamy sauce. In a medium bowl, combine the squeezed cucumber, Greek yogurt, garlic, lemon juice, and fresh dill. Season with salt. Cover and refrigerate. The flavor improves as it sits.

Step 3: Preheat your grill or grill pan to medium-high heat. You want the grates hot enough that a drop of water sizzles immediately on contact. Remove chicken from the marinade and grill for 6 to 8 minutes per side. The chicken should look deep golden with clear grill marks. It is done when the internal temperature reaches 165 degrees F (74 degrees C) on an instant-read thermometer. Avoid pressing down on the chicken while it cooks as this squeezes out the juices.

Step 4: Transfer the grilled chicken to a cutting board and let it rest for 5 minutes. Do not skip this step. Cutting too soon lets all the juices run out. After resting, slice into thin strips against the grain.

Step 5: Warm the tortillas on the grill or in a dry skillet over medium heat for about 30 seconds per side. Warm tortillas are pliable and much easier to fold without cracking.

Step 6: To assemble your grilled Mediterranean chicken tacos, spread a generous spoonful of tzatziki onto each tortilla. Layer on the sliced chicken, then add feta cheese, Kalamata olives, red onion, cherry tomatoes, and fresh parsley.

Step 7: Serve immediately with extra tzatziki on the side for dipping. Once assembled, these tacos should be eaten right away.

Tasty Ways to Round Out Your Meal

These grilled Mediterranean chicken tacos pair well with light, fresh sides that echo the Mediterranean flavor profile without competing with the toppings.

Greek Salad: A simple mix of cucumber, tomato, Kalamata olives, red onion, and feta with a lemon-oregano vinaigrette mirrors every flavor in the tacos and adds a refreshing crunch on the side.

Roasted Vegetables: Zucchini, bell peppers, and eggplant roasted with olive oil and dried herbs bring a warm, savory element that works naturally alongside the best sides for grilled Mediterranean chicken tacos.

Pita Bread with Hummus: A small basket of warm pita with creamy hummus turns this into a full Mediterranean spread. Great for feeding a group without extra cooking.

Lemon Rice Pilaf: Fluffy rice cooked with lemon juice, butter, and herbs soaks up any extra tzatziki beautifully and rounds out the meal without feeling heavy.

Keeping Leftovers Fresh and Ready to Go

Store all components separately in airtight containers in the refrigerator for up to 3 days. Keeping everything separate prevents the tortillas and toppings from getting soggy. The tzatziki sauce keeps well for up to 4 days and the flavor actually deepens overnight, so making it a day ahead is a smart move.

To reheat the grilled chicken, warm it gently in a skillet over medium-low heat with a small splash of water or olive oil to keep it from drying out. The microwave works too in 30-second intervals covered with a damp paper towel. Avoid high heat either way. Assemble fresh tacos to order rather than storing them assembled.

I recommend doubling the tzatziki batch whenever you make these grilled Mediterranean chicken tacos. It keeps for 4 days and works as a dip for raw vegetables, a spread on sandwiches, or a sauce for simple grilled proteins all week.
