Feta Olive Chicken Burgers

Steps

1. 1

   Mix the patties

   • In a large bowl, combine the ground chicken, crumbled feta, chopped kalamata olives, panko breadcrumbs, egg, minced garlic, fresh oregano, salt, and black pepper.
   • Add red pepper flakes if using.
   • Using your hands, gently mix just until the ingredients are evenly combined—do not overmix, as this makes the burgers dense and tough.
   • The mixture should feel loosely bound but hold together.

   Ready when: Mixture is evenly combined and holds together when pressed

   Tip: Overmixing develops gluten in the breadcrumbs, resulting in dense, compact burgers. Use your hands and stop as soon as everything is just combined.

2. 2

   Shape and chill

   • Divide the mixture into 4 equal portions (about 170 g / 6 oz each).
   • Gently shape each into a burger patty roughly ¾ inch thick and 3½ inches wide.
   • Make a small indent in the center of each patty with your thumb to prevent puffing during cooking.
   • Place the burgers on a parchment-lined plate, cover loosely with plastic wrap, and refrigerate for at least 30 minutes.
   • This helps the patties hold together and cook more evenly.

   Ready when: Patties are firm and cold to the touch

   Tip: The indent prevents the burger from puffing into a dome, which would make it harder to cook evenly and to build a burger.

3. 3

   Make the sauce

   • While the burgers chill, stir together the Greek yogurt, fresh lemon juice, 1 teaspoon of the minced garlic (from the 2 cloves used in the patties, or use fresh), and a tiny pinch of salt.
   • If using dill, fold it in gently.
   • Taste and adjust lemon and salt.
   • This sauce can be made up to 2 hours ahead and kept in the fridge.

   Ready when: Sauce is smooth, bright, and well-seasoned

   Tip: The tangy yogurt sauce provides the moisture that mayo would normally give, while keeping the burger lighter and more Mediterranean in flavor.

4. 4

   Heat the grillOven 400°F / 205°C

   • About 15 minutes before cooking, preheat your grill to medium-high heat, aiming for 400°F (200°C).
   • Lightly oil the grates using a damp paper towel and tongs.
   • The grill is ready when you can hold your hand 2–3 inches above the grates for only 3–4 seconds before pulling away.

   Ready when: Grates are hot and lightly oiled; hand test shows intense heat

   Tip: Oiling the grates prevents the delicate chicken burgers from sticking and tearing. A gas grill is easier to control; if using charcoal, allow coals to settle into an even layer.

5. 5

   Grill the burgersOven 165°F / 75°C

   • Place the cold burgers directly on the oiled grates with space between each one.
   • Do not press them down—this squeezes out moisture and makes them tough.
   • Grill for 5–6 minutes on the first side without moving them.
   • Flip once and grill the second side for another 5–6 minutes, until the internal temperature at the center of the thickest patty reaches 165°F (74°C) on an instant-read thermometer.
   • The burgers should have a light golden-brown crust and feel firm but still springy.

   Ready when: Internal temperature is 165°F (74°C); crust is golden and light char marks are visible; patties feel firm but not hard

   Tip: Resist the urge to press or flip repeatedly. Flattening the patties squeezes out the juices that keep them tender. Flip only once for the most even cooking.

6. 6

   Toast and assemble

   • In the final minute of cooking, place the burger buns (cut side down) on the cooler edge of the grill or on a top rack to warm and lightly toast, about 30–45 seconds.
   • Transfer the cooked burgers to a clean plate and let them rest for 2 minutes.
   • Spread a generous spoonful of the yogurt-herb sauce on the bottom bun, add the burger, and top with cucumber slices, tomato slices, and additional sauce if desired.
   • Add the top bun and serve warm.

   Ready when: Buns are warm and lightly golden; burgers have rested and are ready to serve

   Tip: Resting the cooked burger for just 2 minutes keeps it juicy when you bite into it. If assembled immediately while piping hot, the carryover heat can overcook the center.
