This is a grilled chicken breast marinated in olive oil, lemon, garlic, and oregano, served on a toasted bun with homemade tzatziki, lettuce, tomato, red onion, and optional feta. The honest reason to make it tonight: the whole thing takes 30 minutes, the tzatziki comes together while the chicken marinates, and there are very few components anyone at the table will refuse.
The technique that matters
Two things decide whether this burger is good or dry and bland. First, get the grill pan genuinely hot before the chicken goes in — a medium-high pan that’s had 2 minutes to preheat gives you a proper sear that locks in moisture. If the pan is lukewarm, the chicken steams instead of charring, and you lose the flavor the marinade was building. Second, drain the cucumber for the tzatziki thoroughly. Grated cucumber holds a surprising amount of water. Press it in a paper towel until no more liquid comes out, otherwise the sauce turns watery within minutes and slides right off the bun.
If something goes sideways
- Chicken is cooked through but tough: The breasts were probably too thick. Next time, slice them horizontally into cutlets before marinating so each piece is roughly even in thickness and cooks faster with less time on the heat.
- Tzatziki tastes flat: Add a small squeeze of extra lemon juice and a pinch more salt just before serving. The flavor dulls if the sauce sits in the fridge for more than an hour without a quick stir and taste.
- Chicken is sticking to the pan: The pan wasn’t hot enough, or the chicken was moved too soon. Leave it alone for the full 6–7 minutes per side — it releases naturally once a crust forms.
- Buns are soggy before you even sit down: Spread the tzatziki on both cut sides of the bun right before assembling, not ahead of time. The sauce is wet enough to soak through a toasted bun within a few minutes.
- Feta is overwhelming for some eaters: Skip the feta — not worth the extra dish if anyone at the table is sensitive to strong salty flavors. The tzatziki already carries the burger.
Smart swaps
- Greek yogurt in the tzatziki: Full-fat works best for a thick, creamy sauce. Low-fat Greek yogurt is fine but will be slightly looser. Regular plain yogurt is too thin — strain it first if that’s all you have.
- Fresh dill: If you only have dried dill, use half the amount. Dried dill is more concentrated but loses the fresh, grassy note. It still works.
- Chicken breast: Boneless, skinless chicken thighs are a direct swap and stay juicier on a hot pan, especially if the chicken sits a minute too long. Same cook time applies.
- Burger buns: A sturdy brioche bun or a pita pocket both hold up well here. A soft sandwich bun will collapse under the tzatziki — toast it a little longer than you think you need to.
Keeping and reheating
Store the grilled chicken and the tzatziki separately in airtight containers in the fridge — chicken keeps for up to 3 days, tzatziki for up to 2 days before the cucumber starts to break down and water out. To reheat the chicken, use a dry skillet over medium heat for 2–3 minutes per side rather than the microwave, which makes it rubbery. The tzatziki is served cold, so just stir it and it’s ready. Don’t freeze the tzatziki — the yogurt separates when thawed. The cooked chicken can be frozen for up to 2 months; thaw overnight in the fridge before reheating.
Greek Souvlaki Chicken Burger
Equipment
- Grill pan
- Mixing bowls
- Sharp knife
- Cutting board
- Spatula
Ingredients
For the Souvlaki Marinade:
- 1 lb chicken breast, boneless and skinless
- 2 tbsp olive oil, extra virgin
- 1 tbsp fresh lemon juice
- 2 cloves garlic, minced
- 1 tsp dried oregano preferably Greek oregano
- ½ tsp salt
- ¼ tsp black pepper, freshly ground
For the Tzatziki Sauce:
- 1 cup Greek yogurt
- ½ cup cucumber, grated and drained remove excess water with a paper towel
- 1 tbsp fresh dill, chopped
- 1 tbsp fresh lemon juice
- 1 clove garlic, minced
- ¼ tsp salt
For the Burger Assembly:
- 4 pieces burger buns, lightly toasted
- 1 cup lettuce, shredded
- 1 cup tomato, sliced preferably organic
- ½ cup red onion, thinly sliced
- 4 oz feta cheese, crumbled optional
Instructions
- In a mixing bowl, combine the olive oil, lemon juice, minced garlic, oregano, salt, and pepper. Add the chicken breast, ensuring it's thoroughly coated. Let it marinate while preparing other components, about 5-10 minutes.
- For the Tzatziki Sauce, combine Greek yogurt, grated (and drained) cucumber, dill, lemon juice, minced garlic, and salt in another bowl. Mix until smooth and set aside.
- Heat a grill pan over medium-high heat. Once hot, grill the chicken breasts for about 6-7 minutes per side, or until cooked through and nicely charred. Feel for firmness or check for a temperature of 165°F (74°C) for doneness.
- Assemble the burgers by spreading a generous layer of Tzatziki sauce on the bottom half of each toasted bun. Layer with lettuce, grilled chicken, tomato slices, red onion, and feta cheese, if using. Top with the other half of the bun.
Notes
Jen’s Tips:
- For added depth, marinate the chicken for 2-3 hours in advance.
- Substitute Greek yogurt with a dairy-free alternative for a lactose-free option.

Your questions, answered
Can I use store-bought tzatziki instead of making it?
Yes, store-bought tzatziki works fine here. The homemade version takes about 5 minutes and tastes noticeably fresher, but a good refrigerated store-bought tzatziki is a reasonable shortcut on a busy night.
Do I have to marinate the chicken for hours, or is 5–10 minutes really enough?
Five to ten minutes is genuinely enough for good flavor on a weeknight. A longer marinade of 2–3 hours adds more depth, but the lemon and garlic work quickly on thin chicken breast — you won’t end up with a bland burger either way.
How do I know the chicken is cooked without a thermometer?
Press the center of the thickest part — fully cooked chicken feels firm with no give, similar to the base of your thumb when your hand is relaxed. The safest check is still an internal temperature of 165°F, but the firmness test is reliable once you’ve done it a few times.
Can I cook this on a regular skillet instead of a grill pan?
Yes, a heavy skillet works well. You won’t get grill marks, but the flavor is essentially the same. A cast iron skillet is ideal because it holds heat evenly and gives you a good sear.
Is there a way to make this without the red onion?
Just leave it out — the burger holds together fine without it. If you want some mild onion flavor without the sharpness, thinly sliced green onion is a gentler substitute.
Can I prep any part of this ahead of time for a faster dinner?
The tzatziki can be made up to a day ahead and kept covered in the fridge — stir before serving. You can also slice the tomato and lettuce in advance and keep them refrigerated. The chicken marinates while you prep everything else, so there’s no real time savings in marinating it ahead unless you want the deeper flavor.
