How long can a quart of Dairy Queen soft vanilla ice cream last in my freezer?

Nope, it’s ruined if you let it freeze. Better eat it now unless it’s already frozen solid.

@ARE_you_kidding_me O.K. thanks. I took it out of the freezer and, put in fridge.will munch over today and maybe tomorrow. Eating now. I’m happy. Is delicious will eat over night while listening to Atlas Shrugged.

You need to keep it in the freezer when noteating it. It will keep for weeks there.

@janbb Put back in freezer for later tonight. It seems too complicated for ice cream. Will eat tonight and tomorrow during hot weather. At my leisure. @ARE_you_kidding_me Unless you want to add anything?

Until you eat it all?....

Keep it frozen and it could last forever. But the longer it sits in there, the bigger the ice crystals are that form in the mixture.

It’ll never be the same, when it freezes it will be like a flavored ice block and it will not thaw back to soft serve icecream, it will be liquid.

I have had soft ice cream last for a week in the freezer.
If freezing caused damage, how would Dairy Queen be able to store it?

It depends on how cold your freezer is. I keep soft gelato in mine and it doesn’t crystallize.

All you have to do, is melt it, then put it in a blender with liquid nitrogen.
Bam, ice cream without crystals.

It is stored as a liquid in a bag that feeds the soft serve machine. The machine cools it quickly in a specific way where it comes out silky smooth. Those conditions will not be replicated by a freezer. If the mix has propylene glycol added it could be just fine. 25 years ago when I worked there it did not.

I did not know that. I bought soft serve ice cream from the supermarket, which stored it in a freezer. Not as soft as Dairy Queen, but still pretty good. I have also kept DQ ice cream in the freezer without any problems.

Some formulas store well others don’t. Depends on if anti-freeze is added.

Ate half of it. Was awesome. Thanks @all.

Last half turned to liquid in fridge. Drank it like a milkshake. Was good very little waste. Just chucked the head.

You could have left in the freezer, especially if you got a plastic cap for it. I have done that and it works fine. You take what you need and give a minute or two to soften.
