Arrange the orange and onion slices in the bottom of the Dutch oven, alternating between orange slice and onion slice.
1 yellow onion, 1 naval orange
Pat the turkey breast dry. Leaving the netting on, rub the herb mixture all over the turkey breast. Place on top of the bed of orange and onion slices in the Dutch oven.
3 pound boneless turkey breast
Place Dutch oven, uncovered, into the oven and roast for 90 minutes. Drizzle over the remaining tablespoon of olive oil at the 60-75 minute mark.
3 tablespoons extra virgin olive oil
Once the innermost temperature of the turkey reaches 160-165°F, remove turkey breast from the oven. Let rest for 10-15 minutes, then carefully remove netting.
Carve turkey breast with a sharp knife, arrange slices on a platter, then serve and enjoy.
