Pat the turkey breast dry with a paper towel to remove excess moisture. Brush the turkey breast on all sides with olive oil and place it in a parchment-lined air fryer basket.
2 ½ pounds turkey breast, 2 tablespoons olive oil
In a small bowl, mix together the onion powder, garlic powder, thyme, paprika, oregano, salt, and pepper. Sprinkle the spice mix over the turkey breast, rubbing it in to cover all sides.
½ teaspoon onion powder, ½ teaspoon garlic powder, ½ teaspoon thyme, ½ teaspoon paprika, ½ teaspoon oregano, Salt and pepper
For the glaze, combine the maple syrup and mustard in a bowl, stirring until smooth.
¼ cup maple syrup, ¼ cup mustard
Preheat the air fryer to 325°F (160°C) and cook the turkey breast for 45 minutes to 1 hour, checking periodically for doneness. When the internal temperature reaches 160°F (73°C), remove the turkey breast and brush it generously with the glaze.
Place the turkey back in the air fryer for an additional 4 minutes, allowing the glaze to caramelize and the skin to become golden brown. Remove the turkey from the air fryer, let it rest for a few minutes, then slice and serve with the cooking drippings.
