If it has mostly butter, bread , onions, mushrooms, pecans and tarragon in it, why couldn't I made it the day before and then just stuff it in the turkey the next day? No eggs in it. I could add any stock on the morning of cooking it.
Yours sounds like mine and one year I made it ahead and stuffed. I found the stuffing
was much more "soggy"/wet going into the bird than it usually was. So what I do now is do all the veggies (mine has a lot of celery and parsley also and all are lightly sauteed) in one bag and keep the bread and herbs separate. Then just mix it all in a big bowl on the morning and stuff it. Mine also has no stock. By cooking inside the turkey it gets all the juices from the bird. DEEEElicious!!
I will emphasize--I really saw and tasted a big difference.
I have made my dressing ahead for years. I make it one day before, put it into the crock-pot
then it goes in the fridge. I take it out in the late morning, heat on low and add drippings from the turkey to it several times. Everyone loves it. It has no meat because I have two vegetarians in the family who will not eat the chicken and herb sausage I used to add to the dressing
