Yes to adding chicken broth to the bottom of the pan if you are roasting it. I also tent it with aluminum foil but take it off the last half hour or so of baking to let it brown. Also baste it about every thirty minutes, and add more broth if you need to during cooking. I use the broth and any drippings to make the gravy.
I use leftover turkey to make individual pot pies and then freeze them. You do need to have a good amount of gravy for this to turn out right. I use the really small aluminum pans to make them individual servings. It is a little labor intensive, but oh so good. I make my own pie crust dough. (I tried using the refrigerated dough one time and it wasn’t near as good as the homemade pie crust.). While they dough is chilling, I cut up carrots to boil for about 15 minutes. I throw in some peas for about the last 4 minutes of cooking. I also cut up about two large potatoes in bite sized chunks and boil those in a separate saucepan for about 6 minutes. Heat up the gravy, throw in the drained veggies and some shredded turkey. Add salt and pepper to taste. Each little pie tin gets a big cup full of this mixture - almost to the top. Let them then cool. Roll out your dough to cut individual pieces to cover the top of the pan, and when you place it on top of the mixture cut a few vent holes. I then wrap it in plastic wrap, followed by wrapping it in aluminum foil. Throw those bad boys in the freezer.
When you want one, unwrap it from the foil and plastic, place it frozen on a baking tray, and cook at 375 for at least 45 minutes up to an hour.
When my mom and I cook a turkey breast, we are usually tired of turkey after about 2 days. Using the remaining turkey I usually make a huge bowl of turkey salad with grapes and pecans, and also am able to make about 7-8 of these individual pot pies.
