If not using a probe pre-heat your oven according to directions that came with your turkey (Usually 325 degrees)

Stuff the turkey with lemon, onion, celery and carrots.

Put the vegetables in the neck area and the cavity of the turkey. Layer them so there is a good mixture of them inside. (You don't want all the carrots together, you want some variety amongst the placement of the vegetables.)

Rub the softened butter over the turkey with your hands

Mix together: parsley, basil, salt, pepper, rosemary, sage lemon peel, and onion powder

Rub and pat the herbs into the butter

Place your meat thermometer or set your probe

Time the cooking of the turkey according to directions on cooking time for the weight of your bird

Carve turkey to eat
