Use freezer bags and the water displacement method to remove air
Freezer bags are a great way to store tomato sauce without using plastic containers. They can be laid flat in the freezer and stacked once frozen, making them a space-efficient option. To remove air from the bags and prevent freezer burn, you can use the water displacement method.
First, let your tomato sauce cool down. Then, prepare your freezer bags. It is recommended to only fill the bags about two-thirds full to allow for expansion and to prevent leaks. Seal the bags, leaving a small opening for the air to escape. You can use a toothpick or skewer to keep the bag open at the seal. Next, fill a large bowl with water and carefully submerge the bag, ensuring that no water gets into the bag through the opening. The pressure from the water will force the air out of the bag. Once the air is removed, fully seal the bag and place it in the freezer.
Using this method, you can effectively remove air from your freezer bags, helping to preserve your tomato sauce and save space in your freezer.

Freeze in glass jars, leaving space for expansion
Freezing tomato sauce in glass jars is a convenient way to preserve your sauce without the use of plastic. It is important to note that you should not fill the jars to the brim, as the sauce will expand as it freezes. Here is a step-by-step guide to freezing tomato sauce in glass jars:
First, prepare your tomato sauce as you normally would. Ensure that the sauce is cooled to room temperature before proceeding to the next step.
Next, gather your glass jars. It is recommended to use straight-sided canning jars for ease of freezing and storage. Choose jars of varying sizes depending on your intended use. For example, a half-pint jar may be suitable for a single serving, while you may need quarts when serving company.
Now, carefully ladle the sauce into the jars, being sure to leave some headspace for expansion. It is suggested to leave around 2-3 inches of space at the top of the jar.
After filling the jars, secure the lids tightly. Consider labelling the jars with the date of freezing and any other relevant information.
Finally, place the jars in the freezer. To thaw, simply leave the jar out on the counter for about half a day, or add the sauce directly to a pot and simmer until warmed.
By following these steps, you can successfully freeze and store your homemade tomato sauce in glass jars, reducing your reliance on plastic.

Freeze in airtight containers, leaving 2-3 inches of space
Freezing tomato sauce in airtight containers is an effective way to preserve your sauce without using plastic. It is a straightforward process, but there are a few key steps to follow to ensure your sauce freezes well and is protected from freezer burn.
Firstly, allow your tomato sauce to cool. It is important that the sauce is not frozen while still hot, as this will affect the consistency and could cause it to spoil. Once cooled, ladle the sauce into your chosen containers. It is recommended to use glass containers, as tomato sauce can stain plastic. When filling your containers, be sure to leave 2-3 inches of space at the top. This is crucial, as it allows for the sauce to expand as it freezes. If you fill the container too much, it may shatter or break, ruining your sauce and creating a mess. Secure the containers with a lid, and be sure to label them with the date and contents.
Tomato sauce can be stored in the freezer for up to 6 months. To thaw, simply place the container in the fridge overnight, and then reheat the sauce in a saucepan over medium-low heat.

Freeze in ice cube trays
Freezing tomato sauce in ice cube trays is a convenient way to portion out your sauce and save space in the freezer. Here is a step-by-step guide:
Preparation:
Firstly, prepare your tomato sauce as you normally would. It is important to let the sauce cool down before pouring it into the ice cube trays.
Portioning:
Pour the cooled sauce into silicone ice cube trays, filling each compartment evenly. Leave some space at the top of each compartment to allow for expansion during freezing.
Freezing:
Place the filled ice cube trays in the freezer and leave them until the sauce is completely frozen. This step may take several hours or even overnight, depending on the size of the ice cube tray compartments and the temperature of your freezer.
Storage:
Once the sauce is frozen, pop the cubes out of the trays and transfer them to freezer-safe containers or bags. Label the containers or bags with the date and return them to the freezer.
Thawing:
When you're ready to use the sauce, simply take out the desired number of cubes and thaw them. You can thaw the sauce cubes by leaving them in the refrigerator overnight or adding them directly to a pot and heating them gently until they melt and warm through.
Freezing tomato sauce in ice cube trays is an excellent way to portion and preserve your sauce without relying on plastic storage containers or bags.

Freeze whole tomatoes, then make sauce later
Freezing whole tomatoes is an excellent way to preserve your harvest or store fresh tomatoes before making a sauce. It is a straightforward process that allows you to enjoy the taste of summer tomatoes all year round. Here is a step-by-step guide to freezing whole tomatoes and making sauce later:
Freezing Whole Tomatoes:
- Start by selecting ripe, flavourful tomatoes. The type of tomato is not as important, but ensure they are brimming with flavour.
- If desired, you can skin the tomatoes before freezing. To do this, bring a large pot of water to a boil. Working in batches, place the tomatoes in the boiling water for 30-60 seconds until the skins split open. Then, transfer them to a bowl of cold water. Once cool, slip off and discard the skins, and remove the stems, cores, and any bad spots.
- Place the whole tomatoes into freezer bags. You can also measure and portion them into bags for later use.
- Store the freezer bags in the freezer. Whole tomatoes will keep in the freezer for at least six months.
Making Tomato Sauce:
- When you're ready to make sauce, take the frozen tomatoes out of the freezer and let them thaw. You can speed up the process by thawing them to room temperature or cooking them in a stockpot for 30 minutes.
- Roughly chop the tomatoes using a food processor, blender, knife, or by squishing them with clean hands.
- Heat olive oil in a large stockpot over medium-high heat. Add diced onions and sauté until translucent.
- Add the tomatoes and any desired seasonings. For a basic tomato sauce, you can use garlic, salt, oregano, and paprika.
- Simmer the sauce for 45 minutes to an hour, stirring occasionally. Adjust the cooking time based on the desired consistency and the amount of liquid in your tomatoes.
- Taste and adjust seasoning as needed. You can add a little sugar or honey to balance out the acidity.
- Let the sauce cool down to room temperature before freezing.
Freezing the Tomato Sauce:
To freeze the tomato sauce without plastic, you can use freezer-proof glass jars or stainless steel containers. It is recommended to leave some space at the top of the container to allow for expansion during freezing. Additionally, ensure the sauce is cooled completely before transferring it to the freezer to prevent moisture buildup and potential spoilage.
