Full Ingredients
For the Turkey Patties
- 1 lb (450 g) ground turkey, 93% lean
- 2 packed cups finely chopped baby spinach (about 3 oz / 85 g), lightly wilted and squeezed dry
- 1/2 cup (3 oz / 85 g) crumbled feta
- 1/4 cup finely minced red onion
- 2 garlic cloves, minced
- 1 1/2 tsp dried oregano
- 1/2 tsp ground cumin
- 1 tsp lemon zest (from 1 lemon)

Quick Homemade Tzatziki (Optional, Makes About 1 Cup)
- 1 cup (240 g) plain Greek yogurt
- 1/2 cup finely grated cucumber, squeezed very dry
- 1 tbsp fresh lemon juice
- 1 small garlic clove, finely grated
- 1–2 tbsp finely chopped fresh dill
- 1 tbsp extra-virgin olive oil
- 1/4 tsp kosher salt, plus a pinch black pepper
To Serve
- 4 whole-grain burger buns
- 3/4 cup tzatziki (from above or store-bought)
- 1 cup thinly sliced cucumber
- Optional: tomato slices, extra dill, lemon wedges

Step-by-Step Instructions
Step 1: Make the tzatziki
In a bowl, combine Greek yogurt, grated and squeezed-dry cucumber, lemon juice, grated garlic, dill, olive oil, salt, and pepper. Stir until creamy and well combined. Refrigerate to let flavors meld while you prepare the burgers.
Step 2: Prep and dry the spinach
Finely chop the baby spinach. Quickly wilt it to remove excess moisture: microwave in a bowl for 45–60 seconds or sauté in a dry skillet over medium heat for about 1 minute. Spread on a plate to cool, then squeeze firmly in a clean towel or paper towels until very dry. Excess moisture can make patties loose, so really wring it out.
Step 3: Mix and form the patties
In a large bowl, gently combine ground turkey, dried spinach, feta, red onion, garlic, oregano, cumin, lemon zest, salt, and pepper. Mix with a fork or your hands just until evenly distributed; avoid overworking. Divide into 4 equal portions and shape into 1/2-inch-thick patties, about 4 to 4 1/2 inches wide. Press a shallow thumbprint in the center of each to prevent doming. Keep patties chilled until grilling.
Step 4: Preheat and prep the grill
Preheat the grill to medium-high heat (about 425°F/220°C). Clean the grates thoroughly, then oil them. Brush patties lightly with olive oil on both sides to reduce sticking.
Step 5: Grill to juicy perfection
Place patties on the grill, indent-side up. Grill uncovered for 4–5 minutes. Flip carefully and cook another 4–5 minutes, or until an instant-read thermometer inserted into the center registers 165°F (74°C). Avoid pressing on the burgers. Transfer to a plate, tent loosely with foil, and rest for 3 minutes to re-distribute juices.
Step 6: Toast buns and prep toppings
While the patties rest, toast buns cut-side down on the grill for 30–60 seconds until lightly crisp. Arrange cucumber slices and any optional tomato and dill so assembly is quick.
Step 7: Assemble and serve
Spread tzatziki generously on the top and bottom buns. Add a turkey patty, layer on cucumber slices (and tomato if using), sprinkle with dill, and finish with a squeeze of lemon. Serve immediately with extra tzatziki on the side.
Pro Tips
- Squeeze spinach very dry; waterlogged greens make patties fragile.
- Keep the mixture cold and handle it minimally for tender burgers; a light touch prevents toughness.
- Use a thumbprint in the center of each patty to keep them flat as they cook.
- Always cook turkey to 165°F (74°C). An instant-read thermometer ensures perfect doneness.
- No grill? Use a hot cast-iron skillet with 1 tbsp oil over medium-high heat, 4–5 minutes per side.
Variations
- Olive and sun-dried tomato: Fold 2 tbsp chopped Kalamata olives and 2 tbsp chopped sun-dried tomatoes into the meat mixture.
- Herb swap: Replace oregano with 1 tbsp finely chopped fresh mint or parsley for a brighter profile.
- Lettuce-wrap bowls: Skip the bun and serve patties over greens with cucumbers, tomatoes, and tzatziki.
Storage & Make-Ahead
Uncooked patties can be formed up to 24 hours ahead; cover tightly and refrigerate. To freeze, place formed patties on a parchment-lined sheet until solid, then wrap and store up to 3 months; thaw overnight in the fridge before cooking. Cooked patties keep 3–4 days refrigerated; reheat in a 300°F (150°C) oven for 8–10 minutes or in a skillet over medium heat until warmed through. Tzatziki keeps 2–3 days refrigerated; stir before serving. Store cucumbers and buns separately for best texture.
