Grind boneless, skinless chicken thighs using a meat grinder.
Roughly chop the onion, then use a food processor to mince very finely. Add onion to a coffee filter or sturdy paper towel and squeeze out all the liquid.
Add ground chicken, onion, and crushed garlic to the food processor bowl. Add 5 tablespoons of gyro seasoning. Pulse food processor until all the ingredients are combined and you're left with a paste. Place in the refrigerator and marinate for a couple of hours.
Add half of the chicken mixture to a piece of parchment paper (the same size as your baking sheet). Cover with saran wrap; secure plastic wrap to the counter. Gently flatten mixture with your hands, then roll with a rolling pin over the plastic to get it as thin as possible. Repeat with the remaining mixture.
Score with a pizza slicer into strips and freeze in the pan until hard enough to peel off the parchment paper and separate the slices.
Cooking Instructions
Cook the strips in a pan or an air fryer, or freeze in ziplock bags for future enjoyment.
Second Option: Instead of scoring, bake the entire sheet in the oven at 425 degrees for 6 to 8 minutes. Drain excess liquid halfway through, if needed. Slice into strips using a pizza slicer and enjoy!
Notes
Nutrition info is for gyro meat only.
Marinating the chicken mixture overnight enhances flavor!
As you flatten out the meat mixture, you may occasionally need to lift the plastic and redistribute some of the meat to fill in the gaps.
Make sure the chicken gyro strips are completely frozen before storing in a ziplock bag in the freezer, otherwise, they will stick together and be hard to separate.
You can use the leftovers from this chicken gyro recipe to make Greek gyro pizza.
Wrap half of the gyro sandwich with parchment paper or aluminum foil to keep the ingredients from spilling out and to make it easier to eat.
Low-Carb Version: Serve the components over a bed of lettuce instead of pita.
Store gyro meat leftovers in an air-tight container in the refrigerator up to 5 days.
Gyro meat can also be frozen in freezer bags for up to 3 months or longer!
