Wash and dry potatoes.
Combine salt, pepper, and thyme in a small ramekin. Brush potatoes with olive oil, then evenly sprinkle with seasoning.
Prepare the creamy bleu cheese topping. Combine bleu cheese, heavy cream, minced garlic, and bacon bits in a small mixing bowl. Whisk until smooth.
Slice bleu cheese thin, about ⅛. “
Use a Hasselback slicing rack to slice potatoes thinly. If you do not have one, place the potato between two wooden spoons and cut ¼” slices into the potato using the spoons as a stopping point. You do not want to slice all the way through.
Preheat the air fryer to 350 degrees F, Air Fryer Setting, for 5 minutes.
Combine melted butter, thyme, and peppercorn in a ramekin or small bowl—brush butter over and into the potatoes. Place a slice of bleu cheese between each potato fold.
Place potatoes into the air fryer basket and cook for 20 minutes. Brush the tops of the potatoes with the melted butter again, and cook for 7 more minutes.
Top potatoes with a dollop of the creamy bleu cheese mixture and top with chopped chives.
Plate, serve, and enjoy!
