In this article, we will answer the question “Can you freeze spaghetti sauce in glass jars?”, and how to defrost and reheat pasta sauce?
Can you freeze spaghetti sauce in glass jars?
Yes, you can freeze spaghetti sauce in glass jars. However, this is not the wisest choice. The glass container is at risk of cracking and shattering into shards as the liquids inside it expand during freezing.
This creates a mess in your freezer and is a waste of your money. Your best bet is to opt for a freezer bar or air-tight plastic containers because they do not burst under pressure.
Can you freeze spaghetti sauce?
Yes, you can freeze the spaghetti sauce, whether homemade or store-bought. This only applies to tomato-based spaghetti sauces.
Cream-based spaghetti sauces are not made for the freezer. The dairy ingredients in such sauces undergo phase separation during freezing which ruins the texture of the sauce. If you want to freeze cream-based spaghetti sauce, save the cream for after the reheating.
Similarly, you should expect a change in the texture and taste of the frozen pasta sauce if it contains veggies like celery. Moreover, the aroma of the herbs like parsley, basil, cilantro, etc will be closet during freezing and reheating.
You can compensate for the herbs by adding some at the end of the reheating along with a tad bit of sugar to balance the flavor.
Whether the store-bought spaghetti sauce contains meat, veggies, or herbs, it can be safely frozen and thawed. You just need to follow the instructions correctly. A meat-based (bolognese) sauce will keep good for about 3 months in the freezer, and longer in the deep freezer.
If unopened, the spaghetti sauce should be frozen in its original containers. To store the leftovers of the store-bought spaghetti sauce, you need to transfer the leftovers to a freezer bag or an air-tight container.
How long does an opened pasta sauce last?
Pasta sauce has an indefinite shelf-life in the freezer. But the nutritional value and the quality of the pasta sauce continue to decrease over time with noticeable changes in the taste and texture after the 6 months of freezer storage.
|Storage||Average temperature||Maximum time|
|At room temperature||68 – 72°F (20 – 22°C)||2 hours|
|In the fridge||40°F (4°C)||5 days|
|In the freezer||0°F (-18°C)||6 months|
How to defrost pasta sauce?
In the fridge
This is the safest way to defrost any frozen food. All you have to do is to remove the pasta sauce from the freezer and put it in the fridge overnight. The slow thawing will minimally affect the quality characteristics of the pasta sauce.
If the pasta sauce was frozen in a freezer bag, put the bag inside a bowl or plate before refrigerating it. The bowl or plate will catch the drips if there are any.
In the microwave
Defrosting the pasta sauce in the microwave is not the best option out there and hence not recommended. Because microwaving does not evenly defrost your frozen food.
When pressed for time, you can rely on the microwave to quickly thaw your pasta sauce. Remove the pasta sauce from its container and transfer the frozen block to a microwave-safe dish.
Microwave the sauce for about 4-7 minutes, on low or defrost setting. This should take you about 4-7 minutes, depending on how much pasta sauce you are defrosting at a time.
How to reheat pasta sauce?
In a saucepan
Lightly grease the saucepan with some olive using our fingers, paper towel, or a brush. Heat the pan over a medium flame. Then transfer the pasta sauce to the preheated pan. Reheat the sauce over medium-low heat.
If the sauce thickens during reheating, you can adjust its consistency by adding a splash of broth, stock, pasta water, or plain water to it. Adding stock, broth or pasta water to the pasta sauce not only this it out but also adds to its flavor.
Adding 1-2 basil leaves into your pasta sauce towards the end of reheating helps introduce a mild pepper flavor to your sauce. This is another tip to improve the flavor of the reheated sauce.
In the microwave
Transfer the pasta sauce to a microwave-safe dish or bowl. Add 1-2 tablespoons of plain water to the sauce and stir to combine.
Microwave the sauce on high power for about 1-1.5 minutes depending on the amount of sauce that you are reheating at a time. Check the sauce after every 30-seconds interval to make sure it does not scorch.
