Rinse and pat dry the Brussels sprouts, removing the top leaves if they are dry or yellow. Cut each cabbage in half and place in a bowl.
Add salt, spices, thyme and olive oil to a bowl. You can use other oils (avocado, canola, sesame, rapeseed). Mix thoroughly.
Transfer the Brussels sprouts to the air fryer basket in a single layer. Cook at 320F for 5-6 minutes.
After frying, the Brussels sprouts will decrease in size. Transfer it more compactly to one part of the basket, sprinkle with grated parmesan and bake for another 2 minutes.
The roasted aromatic dish can now be transferred to plates and served.
For serving, you can also use fresh herbs - parsley, thyme, basil.
