Can you freeze a Pecan Pie

I've frozen custard pies and they keep well. Be a bit careful when defrosting: if you leave it out in a humid environment, condensation will soak into the crust and make it soggy. Some tips: wrap some foil around the crust on the edges, freeze in a bag,and defrost in the fridge (still in bag). After it is defrosted (at least mostly), keep the foil in place and put it into a hot oven for 5-10 minutes to crisp up the crust and dry out any condensation that has formed.

I've kept pies for a week, and there were no issues. I imagine they will keep for something between 1 and 3 weeks if refrigerated, so there is no reason to freeze if you plan to eat them within a week.

Soup freezes great in my experience. To freeze it for long term storage, you'll probably want it to be vacuum sealed. In order to do this I freeze individual sized portions in Tupperware-style containers (make sure to leave enough room for expansion), and as soon as they're solid, vacuum seal those large "cubes". They generally stack pretty nicely in our garage freezer.

In general soups should thaw and taste very good, some flavors even seem become stronger or seem to enhance and meld better with the freezing. If you vacuum seal them as above you can throw them (still sealed) into a pot of boiling water for hot soup relatively fast!

As an aside, another great option with a leftover turkey frame would be to save it with previous odds and ends (carrot/celery ends, onion pieces, etc) in the freezer, and when you have enough make a simple stock. You can then freeze the stock into cubes (in ice cube trays) for soup-making later, sauteeing veggies, in place of water for more flavorful rice, and a ton of other things.
