Season inside of turkey cavity generously with about salt and pepper powder.
In a medium bowl, combine 2 sticks softened butter, 2 tbsp olive oil, 1/2 tbsp lemon zest, 4 tbsp lemon juice, 3 pressed garlic cloves, 1/4 cup chopped parsley, 1/2 tbsp salt, 1/2 tsp pepper.
Mash with a fork until well combined (the lemon juice doesn't easily stir into butter but keep mixing and it will happen after a few minutes.) Take a whiff of it you'll fall in love with how fresh it smells!
Separate the skin from the turkey breast by pushing your fingers under the skin. Do this from the front and the back of the turkey, being careful not to tear the skin.
Stuff 2/3 of the butter mixture under skin then spread the butter around by massaging over the top of the skin. This butter keeps the turkey breast tender, juicy and provides rich flavour.
Rub remaining butter over the outside of the turkey (breast, legs, wings.) Drizzle all over the top of the turkey with olive oil and generously season with salt and pepper; I just love a crisp, salty skin.
Stuff turkey with quartered onion, 4 halved garlic cloves, fresh parsley and quartered lemon, apple and orange wedges.
Tie turkey base and legs together, crossing the legs to better close up the turkey cavity, plus it looks extra fancy on the table.
