You can freeze spaghetti sauce in glass jars if the glass is strong, if there is at least 1/2 an inch of space at the top of the glass so the sauce can expand and if the lid seals tightly. It is best to choose a jar made from freezer proof glass rather than the jar that it comes in. If the glass is thin or damaged it is best to move the sauce into a freezer safe container like Pyrex instead.
Whether you make your own homemade spaghetti sauce or you use sauce that comes from the store, it’s not that uncommon to have leftovers once your meal is over. If you think spaghetti sauce is a good food item to freeze, you’re absolutely right. This article will explore how to safely store your pasta sauce in the freezer.
Freezing Spaghetti Sauce in Glass Jars
Glass jars can be used to freeze spaghetti sauce, but there are certain jars that work better than others.
Glass jars that have straight sides and are wide at the opening and not narrow work best for freezing things such as spaghetti sauce. Choose a thick, strong glass and it is best if it is marked “freezer safe”.
You should also make sure that there around 1 inch of empty space above the sauce in the jar because sauce can expand when it freezes. If you have a standard twist-off lid jar previously used for foods such as honey or jelly, it will work. Finally, you should always store glass jars upright in the freezer, regardless of the foods inside the jar.
It is also important not to leave to much room at the top of the jar. This will allow too much air in the jar causing frost to form on the surface or freezer burn which will affect the taste.
You can also get glass jars that are specially made to freeze foods. It’s a good idea to get them if you freeze lots of spaghetti sauce on a regular basis.
If you’re thinking of freezing the sauce in the same jar it was in when you bought it at the store, you’ll have to be careful. This is because some of these jars are thinner than normal and can break when the sauce is freezing or even when you thaw it out later on.
When choosing a jar to freeze your spaghetti sauce in, make sure it is thick enough to handle being frozen and thawed so that no problems occur. Some thinner jars break whenever they are exposed to a freezing environment, which can be dangerous.
Preparation of Spaghetti Sauce for Freezing
Proper preparation will ensure that your sauce will freeze well and retain its flavor and texture. Here are the steps to follow to prepare your spaghetti sauce for freezing:
Cooking the Sauce
First, cook your spaghetti sauce as you normally would. You can use your favorite recipe or follow the instructions on a store-bought jar of sauce. Be sure to cook the sauce until it is fully heated through and the flavors have melded together.
Cooling the Sauce
Once your spaghetti sauce is cooked, it’s time to cool it down. You should never put hot liquid directly into the freezer, as this can cause the food to spoil. Instead, let the sauce cool down to room temperature before freezing it.
One way to cool down your spaghetti sauce quickly is to transfer it to a large, shallow container, such as a baking dish or roasting pan. This will allow the sauce to cool down more quickly than if you were to leave it in a pot or saucepan. You can also stir the sauce occasionally to help it cool down more quickly.
Once your spaghetti sauce has cooled down to room temperature, you can transfer it to a freezer-safe container. Glass jars are a popular choice for freezing spaghetti sauce, but you can also use plastic containers or freezer bags. Just be sure to leave some extra space at the top of the container to allow for expansion as the sauce freezes.
With these simple steps, you can prepare your spaghetti sauce for freezing and ensure that it will retain its flavor and texture when you’re ready to enjoy it later.
Proper Packaging of Sauce in Glass Jars
When it comes to freezing spaghetti sauce in glass jars, proper packaging is crucial to ensure the sauce stays fresh and safe to eat. Here are some tips on how to package your sauce in glass jars for optimal results.
Choosing the Right Jar
Not all glass jars are created equal, and not all are suitable for freezing. To ensure your spaghetti sauce stays safe, it’s important to choose a jar made from thick, freezer-proof glass. Suitable jars include Mason jars, but not all mason jars are freezer-proof. Look for jars that are labeled as freezer-safe or those made from tempered glass, which can withstand extreme temperature changes.
Choose a jar with a wide mouth to make it easier to pour the sauce in or use a funnel. Canning jars can work great as long as they are made of thick glass.
Filling the Jar
When filling the jar, it’s important to leave enough headspace at the top to allow for expansion as the sauce freezes. Aim to leave at least half an inch of space at the top of the jar. If you’re using a new jar, sterilize it by boiling it for 10 minutes before filling it with sauce.
To make filling the jar easier, use a ladle or funnel to pour the sauce into the jar. Avoid overfilling the jar, as this can cause the jar to crack or break during the freezing process.
Sealing the Jar
To ensure your spaghetti sauce stays fresh and safe to eat, it’s important to seal the jar tightly. Use a lid that fits the jar properly and screw it on tightly. If you’re using a lid with a rubber seal, make sure the seal is in good condition and free from cracks or tears.
Before freezing, label the jar with the date and contents so you can easily identify it later. Store the jar upright in the freezer to prevent the sauce from spilling or leaking.
By following these packaging tips, you can safely freeze your spaghetti sauce in glass jars and enjoy it later.
Freezing Process
When it comes to freezing spaghetti sauce in glass jars, there are a few things you need to keep in mind to ensure that your sauce stays fresh and flavorful. In this section, we will discuss the temperature requirements and placement in the freezer for freezing glass jars of spaghetti sauce.
Temperature Requirements
To freeze spaghetti sauce in glass jars, you need to make sure that the sauce has cooled down to room temperature before putting it in the freezer. This is important because if you put hot spaghetti sauce in the freezer, it can cause the glass jar to crack or break due to thermal shock.
It is also important to note that the freezer temperature should be set to 0°F (-18°C) or lower. Anything above this temperature can cause the spaghetti sauce to spoil or develop freezer burn, which can affect the taste and texture of the sauce.
Placement in the Freezer
When freezing spaghetti sauce in glass jars, it is important to leave some headspace at the top of the jar to allow for expansion as the sauce freezes. This is because liquids expand as they freeze, and if there is not enough space in the jar, it can cause the glass to break or the lid to pop off.
It is recommended to leave at least 1/2 an inch of space at the top of the jar for expansion. Once you have filled the jar with spaghetti sauce and left the appropriate headspace, screw the lid on tightly and place it in the freezer.
It is also a good idea to place the jars in a single layer on a flat surface in the freezer, rather than stacking them on top of each other. This will help to ensure that the jars freeze evenly and do not break or crack due to uneven pressure.
By following these simple guidelines for temperature requirements and placement in the freezer, you can successfully freeze spaghetti sauce in glass jars without any issues.
Thawing and Reheating
If you have frozen your spaghetti sauce in a glass jar, you need to thaw it before reheating it. Here are some safe thawing methods and tips for reheating your sauce.
Safe Thawing Methods
When it comes to thawing your spaghetti sauce, there are a few safe methods you can use:
- Refrigerator: The safest way to thaw your spaghetti sauce is to place the jar in the refrigerator overnight. This will allow the sauce to thaw slowly and evenly. Make sure to place the jar on a plate or in a bowl to catch any drips.
- Cold Water: If you need to thaw your sauce quickly, you can place the jar in a bowl of cold water. Make sure the jar is submerged in the water and change the water every 30 minutes until the sauce is thawed.
- Microwave: You can also thaw your spaghetti sauce in the microwave. Be sure to remove the metal lid and place the jar in the microwave on a microwave-safe plate. Use the defrost setting and check the sauce every 30 seconds until it is thawed.
Reheating the Sauce
Once your spaghetti sauce is thawed, you can reheat it on the stove or in the microwave. Here are some tips for reheating your sauce:
- Stove: Pour the thawed sauce into a saucepan and heat it over low heat. Stir the sauce occasionally until it is heated through.
- Microwave: Place the thawed sauce in a microwave-safe dish and heat it on high for 1-2 minutes, stirring every 30 seconds until it is heated through.
Remember, once you have thawed your spaghetti sauce, you should use it within 3-4 days. Do not refreeze the sauce once it has been thawed.
Can All Spaghetti Sauces Be Frozen?
If you’re thinking that all spaghetti sauces can be frozen successfully, think again. Tomato- and meat-based sauces are fine, but if you choose a cream- or cheese-based spaghetti sauce instead, those should not be frozen.
This is because cheese and cream can lose their flavor when frozen and thawed out later on, so the sauce simply won’t taste the way it should. Certain vegetables (e.g., celery) and certain herbs can also lose their flavor, but there’s something that you can do about this.
When you thaw out the spaghetti sauce, you can simply add some herbs and even some fresh vegetables, including shredded carrots, to pump up the flavor of the spaghetti sauce and make it tasty again.
If you decide to freeze a basic tomato-based sauce with lots of spices, it won’t be a problem. It is also fine to to freeze a meat-based sauce. Whether the meat is diced, minced, or even shaped into meatballs, you can freeze this sauce and thaw it out whenever you need.
Of course, just because you freeze your spaghetti sauce doesn’t mean that you can keep it in the freezer forever. Both homemade and store-bought spaghetti sauces last well in the freezer for up to 6 months.
If you put the sauce in a deep freezer, it’s possible that it will keep for around two years, which is why it is so important to label the container with the date before placing it in the freezer. Use a permanent marker to label the container and remember that freezer burn can set in if you keep your sauce in the freezer for too long.
Alternatives to freezing spaghetti sauce in glass jars
There are great alternatives to freezing spaghetti sauce in glass jars. Plastic bags that seal well such as a Ziploc bag can be used to freeze sauce. The first thing you’ll want to do is make sure the sauce cools down completely before freezing it, but don’t let it sit more than two hours as bacteria can start to grow after that point.
Reclosable plastic bags are perfect because they take up less room in the freezer, are inexpensive to purchase, and are very unlikely to cause freezer burn to the sauce. Once again, even if you’re using reclosable bags to store and freeze your spaghetti sauce, you need to leave some space at the top of the bag.

Make sure that the bag is closed as tight as possible so that no air leaks into it. Use a permanent marker and date the bag before putting it in the freezer. Sealable bags offer advantages that glass jars don’t, such as being stackable which means even more sauce will fit inside. Some people even flatten the bags out so it’s easier to stack them in the freezer.
You could also use freezer proof plastic containers or even stainless steel containers with lids that seal.
Summary
You can certainly freeze both homemade and store-bought spaghetti sauce upright in glass jars. Strong glass jars that are freezer safe (like mason jars) with well sealing lids are fine to put in the freezer. You could also pour extra sauce in Pyrex dishes or any other glass dish that seals well. Remember to leave at least half an inch of space in the top for the sauce to expand.
Keep in mind that sauces with cheese or dairy products usually don’t do well when frozen and thawed out, so you’re better off keeping them in the refrigerator and using them within a few days.
