Preheat the oven to 400°F (204°C).

Add the ground turkey, egg, chopped spinach, crumbled feta, parsley, dill, salt, and black pepper to a large mixing bowl.

Gently combine the ingredients until evenly distributed. Avoid overmixing, which can make the finished burgers dense.

Divide the turkey mixture into six equal portions.

Shape each portion gently into a burger patty of even thickness.

Heat the olive oil in a large oven-safe skillet over medium to medium-high heat.

Once the oil is hot, arrange the patties in the skillet without overcrowding. Work in batches if necessary.

Cook for approximately 3–4 minutes on the first side, until nicely browned.

Carefully flip each patty and brown the second side for another 3–4 minutes. The feta makes the burgers tender, so handle them gently.

Transfer the oven-safe skillet directly to the preheated oven. If your skillet is not oven-safe, transfer the browned patties to a baking sheet.

Bake for approximately 10 minutes, or until the center of each burger reaches 165°F (74°C).
