This Mediterranean-inspired flatbread features tender marinated chicken breast grilled to perfection and served atop warm, pillowy flatbread. The chicken gets its signature flavor from a simple marinade of olive oil, lemon juice, garlic, and oregano, while a homemade tzatziki sauce adds cool, creamy contrast to the savory elements.

Fresh cherry tomatoes, crisp cucumber, red onion, and briny Kalamata olives provide texture and brightness, while crumbled feta cheese adds a rich, tangy finish. A bed of baby spinach or arugula brings a peppery bite that balances the richness of the chicken and cheese.

The entire dish comes together in just 40 minutes, making it perfect for weeknight dinners or casual entertaining. Each serving delivers 28 grams of protein with a satisfying combination of carbohydrates and healthy fats, keeping you full and energized.

The first time I made these Greek chicken flatbreads, my kitchen smelled like a taverna in the middle of a summer afternoon. Lemon and garlic mingled with oregano in a way that made me completely forget I was just standing at my stove in an apartment. They have become my go-to when I want something that feels like a treat but comes together in under an hour.

Last summer I served these at a small rooftop gathering with friends. We ate them standing up, leaning against the railing, watching the sun go down. Someone asked for the recipe mid-bite, which is always the best kind of review.

Ingredients

  • Chicken breasts: Boneless and skinless absorbs the marinade beautifully and cooks quickly on the grill
  • Olive oil: Use a good quality extra virgin here since it forms the base of both the marinade and tzatziki
  • Lemon juice: Fresh squeezed brightens the entire dish and helps tenderize the chicken as it marinates
  • Garlic: Mince it finely so it distributes evenly through the marinade without any harsh bites
  • Dried oregano: The dried version actually works better here than fresh, infusing the oil with that classic Greek flavor
  • Flatbreads: Naan or pita work wonderfully but any soft flatbread will do the job
  • Cherry tomatoes: Halving them releases just enough juice to complement the other ingredients without making things soggy
  • Cucumber: Thin slices add crunch while grated cucumber in the tzatziki brings necessary creaminess
  • Red onion: Slice it paper thin for a sharp bite that cuts through the rich elements
  • Kalamata olives: Their briny punch is essential so do not substitute with milder olives
  • Feta cheese: Room temperature crumbles soften beautifully over the warm chicken
  • Baby spinach or arugula: Arugula adds a peppery kick while spinach stays neutral and lets other flavors shine
  • Greek yogurt: Full fat makes the tzatziki luxuriously creamy and helps it cling to the flatbread
  • Fresh dill: Chopped right before adding to the tzatziki so its bright flavor stays intact

Instructions

Marinate the chicken:
Whisk together olive oil, lemon juice, garlic, oregano, salt and pepper in a shallow bowl. Add chicken and turn to coat thoroughly, letting it sit for at least 15 minutes while you prep everything else.
Make the tzatziki:
Stir Greek yogurt with olive oil, lemon juice, grated and drained cucumber, minced garlic, chopped dill and seasonings. Keep it chilled until you are ready to assemble the flatbreads.
Grill the chicken:
Cook chicken over medium high heat for about 6 minutes per side until it is cooked through and has nice char marks. Let it rest for 5 minutes before slicing into thin strips.
Warm the flatbreads:
Give each flatbread a quick turn in a dry skillet or warm oven for just a minute or two until they are pliable and slightly toasted.
Assemble:
Spread tzatziki over each flatbread then layer on greens, chicken, tomatoes, cucumber, onion, olives and feta. Drizzle with extra sauce and serve while the chicken is still warm.

These flatbreads have become a staple in my kitchen because they hit that perfect balance between satisfying and light. The way the warm chicken meets the cool tzatziki never gets old.

Make Ahead Strategy

The tzatziki actually gets better after a day in the fridge so I often double the batch. You can also grill the chicken ahead and keep it sliced in the refrigerator, warming it slightly before assembling.

Serving Suggestions

I like to serve these with extra lemon wedges on the side so everyone can adjust the brightness to their taste. A simple Greek salad with the same dressing ingredients makes this feel like a complete spread.

Common Questions

Can I use chicken thighs instead of breasts? Absolutely, thighs stay juicier and may need an extra minute or two per side. What if I cannot find Kalamata olives? Any briny cured olive will work but the flavor profile will shift slightly. Can I make this vegetarian? Grilled halloumi or even thick slices of roasted eggplant make excellent substitutes for the chicken.

  • Slice the chicken against the grain for the most tender bites
  • Warm your flatbreads just enough to make them pliable, not crispy
  • Let the assembled flatbreads sit for 2 minutes before cutting so the flavors can meld

These flatbreads have a way of making any Tuesday feel like a special occasion.

Questions & Answers

Yes, you can marinate the chicken up to 24 hours in advance for even deeper flavor. Cooked chicken can also be grilled ahead and refrigerated for 2-3 days, then gently reheated before assembling the flatbreads.

Naan, pita bread, or store-bought flatbread all work wonderfully. Look for flatbreads that are pliable and not too thick, which allows them to warm through without becoming tough or chewy.

Absolutely! Grilled halloumi cheese makes an excellent substitute for chicken. Slice the halloumi thickly and grill for 2-3 minutes per side until golden brown and slightly charred.

Your homemade tzatziki will keep in an airtight container in the refrigerator for 3-4 days. The flavors actually develop and improve after a day, so making it ahead is a great time-saver.

It's best to freeze components separately. You can freeze grilled chicken for up to 3 months and tzatziki for 1 month. Flatbreads freeze well for 2-3 months. Assemble fresh when ready to serve for best texture.

Difficulty Easy

Ingredients

Chicken Marinade

  • 2 boneless, skinless chicken breasts (about 1.5 lbs total)
  • 2 tablespoons olive oil
  • 1 tablespoon fresh lemon juice
  • 2 cloves garlic, minced
  • 1 teaspoon dried oregano
  • 1/2 teaspoon salt
  • 1/4 teaspoon freshly ground black pepper

Flatbread Base

  • 4 flatbreads (naan, pita, or homemade, each about 8 inches diameter)

Fresh Toppings

  • 1 cup cherry tomatoes, halved
  • 1/2 medium cucumber, thinly sliced
  • 1/4 small red onion, thinly sliced
  • 1/2 cup Kalamata olives, pitted and sliced
  • 1/2 cup crumbled feta cheese (about 2 oz)
  • 1 cup baby spinach or arugula leaves

Tzatziki Sauce

  • 1/2 cup plain Greek yogurt
  • 1 tablespoon olive oil
  • 1 tablespoon fresh lemon juice
  • 1/4 cup cucumber, finely grated and well-drained
  • 1 clove garlic, minced
  • 1 tablespoon fresh dill, finely chopped
  • Salt and black pepper to taste

Instructions

1
Prepare Chicken Marinade: Whisk together olive oil, lemon juice, minced garlic, dried oregano, salt, and black pepper in a medium bowl until well combined. Add chicken breasts, turning to coat thoroughly. Cover and refrigerate for at least 15 minutes, up to 1 hour for optimal flavor absorption.
2
Make Tzatziki Sauce: While chicken marinates, combine Greek yogurt, olive oil, lemon juice, grated and drained cucumber, minced garlic, chopped fresh dill, salt, and pepper in a small bowl. Mix until smooth and evenly incorporated. Refrigerate until ready to serve to allow flavors to meld.
3
Grill Chicken: Preheat grill pan or cast iron skillet over medium-high heat until hot. Remove chicken from marinade and discard excess liquid. Grill chicken for 5 to 6 minutes per side, until internal temperature reaches 165°F and juices run clear. Transfer to cutting board and let rest for 5 minutes before slicing thinly across the grain.
4
Warm Flatbreads: Heat dry skillet over medium heat or preheat oven to 350°F. Warm flatbreads in skillet for about 1 minute per side or in oven for 2 minutes until soft and pliable. Avoid over-toasting to maintain flexibility for folding.
5
Assemble Flatbreads: Spread generous layer of tzatziki sauce evenly over each warmed flatbread, leaving slight border at edges. Layer baby spinach or arugula, sliced grilled chicken, cherry tomatoes, cucumber slices, red onion, Kalamata olives, and crumbled feta cheese. Drizzle additional tzatziki over top if desired. Serve immediately while flatbreads are still warm.
