Can I successfully freeze leftover canned crushed tomatoes?

Thanks all! Into the freezer they go...

I like to blend them and freeze them in one cup portions. Add to sauces, soups and braises. Blending the tomatoes prevents a soft texture.

Yes, you can. They'll be a little gooshier after you freeze them, but they should freeze just fine for up to a month. Just make sure to get as much air out as possible.

Go ahead. Depending on what you want to do with them in the future, they may get a bit mushier in texture. Since they are crushed anyway, it shouldn't make any difference in, for example, a cooked sauce. I agree; no point in wasting food; just pack in zipper freezer bags for convenience.
