Wash and slice your potatoes. I'm using a mandolin to slice them thin (¼ inch) so they are more like chips and really absorb the delicious sauce.
Stack your sliced potatoes and slice horizontally.
Season your potatoes with your garlic powder, black pepper, and onion salt. Spray with cooking oil and cook in the air fryer at 400F for 20 minutes or until crispy.
Dice your shallots and set aside.
Melt your butter and truffle oil in a pan and add in your shallots and garlic. Saute until fragrant.
Add in your chicken stock, heavy cream, black pepper, and mushrooms and cook until your mushroom begin to soften.
Add in your white wine and mussels. Cook until all the mussels have open and your mushrooms are fully cooked. This should take around 5-7 minutes. Discard the unopened mussels.
Top with fresh parsley and a drizzle of truffle oil and serve!
