freezing tomato soup

i have done this for years with my own recipe. i make it in the thickest version possible. in other word, i leave out water or stock. I freeze in 2 c potions in freezer bags. i lay the bags flat on a rimmed baking sheet in the freezer so they store easily. then, when i want to use it i can adjust to the thickness I want for either soup or sauce. it works very well. when defrosted you can adjust with wine or fresh herbs for whatever use you choose.

I haven't made that specific recipe, but I make a similar roasted tomato soup (recipe is here) that I've frozen - freezes very well.

Yes, I freeze tomatoes, tomato sauce and tomato soup all the time. I love having summer tomato dishes to pull out in the middle of winter.

I use plastic pint containers from the hardware store for freezing stock, stews, soups, etc. I'll unmold these, then reheat over the stove in a pot, or occasionally microwave in a glass jar. I do not microwave plastic.

You could use glass Mason jars if plastic freaks you out. Sometimes, I run out of plastic pint containers, so I switch to Mason jars.

The square plastic pint containers do stack better and are a more efficient use of space. I buy a new set every couple of years and recycle the old ones.
