Preheat the oven to 375 degrees F. Cover a baking tray with aluminum foil and keep it ready.
In a medium bowl stir together olive oil, lemon juice, Dijon mustard, paprika, oregano, salt, black pepper, garlic powder, thyme and rosemary. Mix well to form a paste.
Spread the spice mixture under the turkey skin and add the remaining spice mixture all over the turkey evenly.
Place the turkey breast over the prepared baking tray and cook for 1 hour until the turkey reaches 160F when checked internally.
Remove the turkey breast and set aside to rest for 10 minutes, covered with foil wrap and then slice and serve.
