1: Rub and season your lamb cutlets with oil, salt, and pepper.
(or your seasoning of choice)
2: Fire up your Ooni pizza oven.
Aim for 662˚F (350˚C) on the stone baking board inside. You can check the temperature inside your Ooni quickly and easily using the Ooni Infrared Thermometer.
3: Place your Cast Iron Pan with some olive oil inside the oven to warm up.
After 1-2 minutes, remove the pan and add your lamb cutlets.
4: Place the pan back in the oven and cook the cutlets for 6-8 minutes, making sure to flip the cutlets halfway through.
5: While your cutlets are cooking, mix together the yoghurt, cucumber, mint, and garlic in a bowl to make the tzatziki.
6: Once the cutlets are cooked to your taste, remove the pan from the oven and transfer the cutlets to a wooden board.
Plate and serve warm with your tzatziki sauce.
