Generously brush potato with melted butter; cook for 15 minutes at 350°F.
Remove from air fryer, brush the grooves with melted butter. Sprinkle grooves with garlic and salt and return to air fryer.
Cook an additional 15 minutes at 350°F.
Remove, let sit for 5 minutes before serving.
Notes
**If you don't have a hasselback slicing rack, try placing the potato between the handles of two parallel wooden spoons. Then using a sharp knife slice ½ inch cuts into the potato. I like to tape the wooden spoons onto a cutting board so that they don't slide around when slicing the potato.
