Preheat the oven to 390F. Put soft butter in a bowl and add salt, dried basil, and thyme leaves.
Mix the butter with the herbs to make a soft spreading paste.
Wash and dry the turkey crown. Carefully separate the skin from the breast and lift it up.
Spread turkey fillet with butter, using a third of the total amount.
Slice a portion of the orange into thin slices (about 1/2 inch thick) and place under the skin. Four pieces will be enough.
Brush the turkey crown all over with the remaining herb butter and salt.
Place the turkey crown in a high-sided roasting dish. Pour 1/2 cup of water into the baking dish. Drizzle the turkey crown with orange juice and place the remaining sliced oranges under the crown. Carefully cover the baking dish with foil and place it in the oven. Bake for at least 1 hour and 40 minutes, then remove the foil and bake for another 20 minutes at 400F to obtain a golden crust. To check the readiness of the turkey crown, you need to puncture the fillet and if clear meat juice comes out, the turkey is ready.
Serve the turkey crown whole or cut it into slices. Can be served both hot and cold.
