Step 1

Microwave your spinach in a bowl for about one minute until it cooks down (you can also cook on the stovetop if you prefer). Wrap in a towel and squeeze out as much liquid as possible. If you're using frozen spinach, you can follow the same steps to make sure you squeeze out as much water as you can.

Step 2

In a large bowl, combine your spinach with the ground turkey and seasonings to make your turkey burger mixture. The mixture will feel very loose, but that is because we are dealing with a very lean ground turkey.

Step 3

Spray your air fryer basket with nonstick cooking spray, or use air fryer parchment paper sheets to line the basket.

Step 4

Break the ground turkey mixture into 4 equal-sized pieces and form them into a ball in your hands. Add two to your air fryer basket and press them down into burger shape inside the air fryer. Since the mixture can be delicate, it's easiest to form the burgers inside of the air fryer.

Step 5

My air fryer fits 2 burger patties, so I made 2 batches, but you can cook all at once if they fit.

Step 6

Air fry the turkey burgers at 350 degrees F for about 10 minutes, carefully flipping them halfway through. Note that cooking time may vary slightly depending on the size of your air fryer, the fat content of the turkey you use, and the size of the burgers you make.

Step 7

While the turkey burgers cook, lightly toast your brioche buns by placing them in a stovetop pan over medium heat until toasted to your liking.

Step 8

Remove the turkey burgers from the air fryer & add them to your buns. Top each cooked burger with sliced cucumber, red onion, tomato, and your tzatziki sauce. I also recommend adding a squeeze of fresh lemon juice on top.
