Pre-heat the air fryer at 400°F for 5 minutes.
In a mixing bowl, add the curd and the spices and mix well.
Add in the halved mushrooms next and coat them well with the curd mixture.
Transfer the coated mushrooms to the air fryer basket and spray a bit of oil on them, and cook them at 350°F for8 minutes.
You can flip them once in between and brush some oil so that they are cooked well.
Then cook them again at 400°F for 2 minutes.
For the green chutney, blend everything together in a blender. Adjust salt and lemon juice if required.
Serve the tandoori mushrooms hot with green chutney.
