Preheat your oven to 375.
Rinse the whole turkey in the sink under cool water, then pat fully dry using paper towels.
10 lb turkey
Remove any excess skin or fat around the neck and tail area, then lean out the turkey's cavity, removing the turkey neck and gizzards.
Use your hands or a plastic spatula to carefully loosen the turkey's skin from the meat.
In a bowl, combine the ingredients for the turkey butter. Then, rub about 3/4ths of the herb butter under the turkey's skin, making sure to get all around the turkey. Use any extra butter left on your hands on the outside of the turkey.
1 1/2 sticks butter, 2 tbsp minced garlic, 1 tbsp ground sage, 1 tsp salt
Season your turkey all over with the seasoning salt, garlic salt, basil, and sage. Fill in any "bald" spots by pressing the seasonings onto the turkey skin.
1 tbsp ground sage, 1 tsp seasoning salt, 1 tsp garlic salt, 1 tbsp crushed basil leaves
Stuff the turkey with the chopped lemon wedges and onions.
2 large lemons, 1 large onion
Place the turkey into the roaster pan and cover with tin foil.
Place the turkey in the oven and bake for 2 hours. Do not open the oven during this time!
Remove the turkey from the oven and baste the turkey using the remaining turkey butter and pan drippings for extra flavor.
Return the turkey to the oven, uncovered, for an additional 30 minutes or until the thickest part of the breast and thigh reach 165 degrees F.
Remove the turkey from the oven, tent it with foil to keep it warm, and let it rest for at least 15 minutes before serving.
Enjoy!
