Preheat Oven : Preheat your oven to 375°F (190°C).
Prepare Turkey : Pat the turkey breast dry with paper towels. Rub the olive oil or melted butter evenly over the surface. Season with salt, black pepper, garlic powder, thyme, rosemary, and paprika.
Prepare Roasting Pan : Place quartered onion and smashed garlic in the bottom of a roasting pan. Pour 1 cup of chicken or turkey broth into the pan to keep the meat moist. Place turkey breast on top.
Roast Turkey : Roast uncovered for 1 hour 15 minutes to 1 hour 30 minutes, or until a meat thermometer inserted into the thickest part reads 165°F (74°C). Baste occasionally with pan juices for extra flavor.
Rest Turkey : Remove the turkey from the oven, cover loosely with foil, and let it rest for 15 minutes. This helps the juices redistribute for a moist roast.
Prepare Gravy : Pour pan drippings into a saucepan, reserving about 2 tbsp fat. Whisk in 2 tbsp flour to make a roux. Gradually whisk in 1 cup broth, stirring constantly until thickened. Season with salt and pepper.
Slice u0026 Serve : Slice the turkey breast and serve with homemade gravy.
