Too much sauce. Most US commercially sold spaghetti sauce jars are between 24 and 32 ounces, some even 45 ounces. That’s a lot of sauce. So, unless you having at friends over for spaghetti night, you are going to have some leftover. An open jar of spaghetti sauce will keep in the fridge 7-10 days, after that it’s probably a little blue and furry, or at least starting to ferment.
- Use up the leftover sauce to making other things. FoodNetwork 50 things to do with leftover spaghetti sauce, I am partial to Tomato Soup with lots of butter and cream.
- Buying smaller jars to start with. In my neck of the woods, there are about three types of ‘plain’ spaghetti sauce sold in 14 ounce jars. Plain is fine I can doctor it up myself, but it is also one third more expensive per ounce, and I still end up with leftover, just not so much.
- Make your own. Starting with an 8oz can of tomato sauce and doctoring it up, smacks a little too much like dorm food. It’s great in a pinch, but do you want to live like that? The other option is to take time out of your week to make a pot of sauce…and if you are going to do that.. you’d be doing it already or you can just buy a ready made jar.
- Freeze it.
- Pour the remainder into ziplock freezer bag. Stand the bag in inside a mug or measuring cup to hold it up. Lay the bag on flat surface or cookie sheet inside the freezer until frozen. Then you can store it sideways.
- Line a cup, mug or muffin tin with a plastic bag or plastic wrap, pour the sauce into the lined container. Place the cup in the freezer, when the sauce is frozen, slide the plastic wrapped chunk out of the cup and then tie the plastic wrap closed and store in the freezer. If it sticks in the container, leave it on the counter for two minutes.
- Pour the leftover sauce into clean recycled yogurt or other plastic container the freeze.
- Designate one or two particular food storage containers for tomato based sauce freezing…don’t make yourself crazy trying to get the tomato stain off plastic, it is just gonna happen every time.
- Pour the extra sauce into a small Ball or other type of canning jar. These jars have a fill line specifically for freezing, but to be safe don’t fill it to that line. Put the cap on very loosely and tighten when it is fully frozen. To thaw, take it out and thaw in the fridge, on the counter or in the microwave without the lid.
- Put the half filled spaghetti sauce jar IN the Freezer, WITHOUT THE LID. You can cover it with a saucer or something if you want. Commercial sauce jars don’t have much thread, so it is difficult to put them on loose enough. Remember water expands and will break the glass if the air can’t leave. Once it is frozen you can put the lid on.
