Step 1

Coat the entire turkey breast in about half of the BBQ Chip Dust. Place on a sheet pan fitted with a rack and let it dry brine in the fridge, uncovered, for 8 hours and up to overnight.

Step 2

Install an air fryer searing plate in an air fryer and set the temperature to 400 degrees F for 35 minutes for the plate to preheat.

Step 3

In a large bowl, toss the parsnips, sweet potatoes and baby potatoes with the avocado oil. Sprinkle with the remaining BBQ Chip Dust and toss until coated.

Step 4

Remove the searing plate and place the turkey breast skin-side down on one side. Arrange the vegetables on the other side. Cook until the turkey skin is golden brown, about 5 minutes (see Cook's Note). Flip the turkey breast and continue cooking until an instant-read thermometer inserted into the thickest part of the breast registers 165 degrees F and the root vegetables are tender, 35 to 40 minutes. Let the turkey rest for 10 minutes.

Step 5

Carefully remove the rib bone (if there is one) from the turkey breast and carve. Serve with the root vegetables.

Step 6

Combine the brown sugar, salt, chile powder, garlic powder, black pepper, onion powder and cayenne in a small bowl and mix until blended. Use immediately or transfer to an airtight resealable container.
