How do you store leftover spaghetti sauce?

In this blog post we will answer the following question: How do you store leftover spaghetti sauce? We will teach you how to store and freeze leftover spaghetti sauce and how you can “recycle” it and make other delicious meals!

How do you store leftover spaghetti sauce?

After cooking, we recommend storing the leftover spaghetti sauce in a jar or other airtight container, in the refrigerator for 3-5 days. It is possible to freeze leftover sauce at any time during this period; just pour the sauce into a container suitable for the freezer, and you can store it for up to 3 months.

How do I freeze leftover spaghetti sauce?

You don’t need to make a sauce from scratch every time. You can certainly make a batch in advance and then freeze it for later. Still, you can’t go wrong with a sauce that separates in the freezer. The fat and water will separate during the freezing process, which will make the sauce look a bit grainy and not at all thick. Do not despair! I’ll show you exactly how to get your béchamel back to its thick, shiny finish in no time.

To freeze, start with a freshly made spaghetti sauce. Allow cooling completely before freezing to avoid freezer burn. Scoop the desired amount of sauce into a freezer bag, leaving some room for expansion. Seal the bag tightly. 

Then, slide the freezer bag into another one and seal the second bag tightly. Label and date the freezer bag and place it in the freezer. This is also a great way to protect against leaks!

Can I freeze the sauce in a jar?

Yes, you can freeze a jar of sauce, and we’ll explain how to do it step by step:

  1. Choose the correct type of glass jar. Ideally, you should use the jars designed especially for canning. The wide-mouthed ones are the best.
  1. Use the lids corresponding to the glass jar you are using. These often come in two parts, the cap and the thread (they also come as a single cap), and are specially made to expand or contract depending on environmental conditions. They even close hermetically, which will protect the food from the damage that the cold can cause.
  1. Wash and dry the glass jar very well before filling it.
  1. Don’t fill it to the brim. Leave a space of 1.25 cm for fruits and vegetables that do not contain added liquid or sugar.
  1. For sauces, soups, and other types of liquid foods, leave 1.25 cm when you use a half-liter jar and leave 2.5 cm. for 1-liter jars.
  1. It is essential to leave this space, as it allows the food to expand when frozen and prevents the jar from breaking and the food from pressing on the lid.
  1. Stir the contents of the glass jar using a spoon or spatula before sealing it. This will release air bubbles and help reduce the expansion of the food.
  1. Clean the mouth of the jar. Any remaining food left in it can prevent proper sealing.
  1. Place the lid on the jar and then seal it with the screw. Tilt the jar slightly to make sure it is tightly closed and that the food doesn’t spill.
