Productivity experts save time by cooking and then freezing meals in advance. Spaghetti makes an ideal candidate for freezing. Whether you're making a week's worth of meals or have simply cooked too much spaghetti for dinner and don't know what to do with the leftovers, you can store cooked spaghetti in your freezer for later use.
Cook your spaghetti to an al dente or firm consistency. Test the consistency by taking a noodle out of the boiling water and throwing it against the wall. It will stick to the wall if it's al dente.
Dry off any excess water by placing the hot spaghetti in a strainer and letting the water drain out of it.
Transfer the spaghetti to a mixing bowl. Add enough olive oil or butter to give the noodles a light coat and mix into the spaghetti with a fork. Adding olive oil or butter will keep the noodles from sticking together during freezing.
Place the still hot spaghetti into a freezer bag. Flatten or pinch dow the bag before zipping or sealing it to remove any excess air. Any excess air present in the bag can cause freezer burn.
Put these bags in a freezer set at a temperature less than zero degrees Celsius.
