Freezing berries without plastic is a great way to preserve the taste of summer berries all year round. It's also a more environmentally friendly option, as it reduces the amount of plastic waste that can accumulate from store-bought frozen berries. The process is simple: first, cut and clean the berries, then spread them out on a baking sheet or cookie sheet and place them in the freezer. Once they're frozen, transfer the berries to airtight containers such as glass jars or stainless steel containers. This method prevents the berries from sticking together and ensures they stay fresh and flavourful.

What You'll Learn
Use stainless steel or glass containers
Using stainless steel or glass containers is an effective way to freeze berries without plastic. This method is ideal for those who want to avoid the waste associated with plastic bags and the potential for freezer burn. It is also a good option for those who want to store food away from plastic due to health or environmental concerns.
To freeze berries using stainless steel or glass containers, follow these steps:
- Prepare the berries: Rinse the berries and remove any stems or leaves. Cut off any damaged spots and slice large berries in half.
- Freeze berries individually: Arrange the berries on a baking sheet or cookie sheet in a single layer. You can line the sheet with parchment paper or a silicone mat to prevent sticking. Place the sheet in the freezer for about two hours or until the berries are frozen.
- Transfer to containers: Once the berries are frozen, transfer them to your chosen containers. You can use wide-mouth mason jars, glass jars, or stainless steel containers. Ensure the containers are airtight and leave some space at the top to allow for expansion during freezing.
- Store in the freezer: Place the containers in the freezer and enjoy the berries at your leisure.
It is important to note that when using glass containers, you should avoid temperature shocks. Allow the berries to cool before placing them in the freezer, and do not fill the jars to the brim to prevent breakage due to expansion during freezing.
By following these steps, you can successfully freeze berries in stainless steel or glass containers without using plastic. This method ensures that your berries remain fresh and flavourful while reducing waste and your environmental impact.

Freeze berries on a cookie sheet first
Freezing berries is a great way to preserve the freshness and taste of the fruit for later consumption. The best option for plastic-free freezing is to use a stainless-steel airtight container or glass jars. Here is a detailed guide to freezing berries on a cookie sheet first:
Firstly, prepare the berries by removing any damaged spots and cutting off the tops of strawberries. It is recommended to cut large strawberries into halves, while smaller berries such as blueberries, blackberries, and raspberries can be left whole.
Next, arrange the berries in a single layer on a cookie sheet or baking sheet. This step ensures that the berries freeze individually and do not stick together in a giant lump. You can also place a sheet of parchment paper or a silicone mat on the cookie sheet to prevent sticking.
Place the cookie sheet with the berries in the freezer for about two hours or until the berries are completely frozen. Once frozen, transfer the berries to your chosen containers.
For storage, wide-mouth mason jars are a popular choice due to their versatility and stackability. Alternatively, you can use large stainless-steel containers, which are a good option if you prefer something non-breakable.
By following these steps, you will have individually frozen berries that are ready for later use and stored in plastic-free containers.

Avoid glass jars with shoulders
Glass jars are a great alternative to plastic when it comes to freezing berries. However, it's important to avoid using glass jars with "shoulders" or curves. These jars are more prone to breaking in the freezer due to the expansion of the frozen contents. The pressure of the expanding frozen food can cause the glass to shatter, creating a safety hazard.
To avoid this issue, opt for straight-sided glass jars without shoulders. These jars allow for the necessary expansion of the frozen berries, reducing the risk of breakage. You can find such jars in various sizes, ensuring a suitable option for your freezing needs.
When using glass jars for freezing berries, it is essential to follow certain practices. Firstly, avoid filling the jars to the brim. Leave some space at the top to allow for the expansion of the frozen berries. Secondly, wait for the berries to cool down before placing them in the freezer. Glass does not respond well to temperature shocks, so allowing the berries to cool first reduces the risk of breakage.
Additionally, consider using plastic storage caps instead of metal caps. Metal caps are not designed for long-term storage and can rust quickly. By following these guidelines, you can successfully freeze berries in glass jars without shoulders, reducing waste and preserving the quality of your berries.

Use cardboard flats from the farmer's market
If you want to freeze berries without plastic, one option is to use cardboard flats from the farmers' market. Many vendors at farmers' markets sell berries in cardboard flats, which can be recycled or composted after use. Some vendors will even take back the boxes for reuse.
To freeze berries using this method, start by rinsing and preparing the berries as needed. Remove any stems or leaves, and cut off any damaged spots. You may also choose to slice large berries in half to make them easier to blend into smoothies.
Next, spread the berries out on a baking sheet or tray in a single layer. This step helps prevent the berries from sticking together in a large clump once frozen. You can also place them on a sheet of parchment paper or a silicone mat to make removal easier. Place the tray of berries in the freezer for a few hours until they are completely frozen.
Once the berries are frozen, transfer them to cardboard flats and store them in the freezer. Using this method, you can enjoy fresh, locally sourced berries all year round without the waste of plastic packaging.

Wash and cut berries before freezing
It is recommended to wash berries before freezing them. However, they need to be completely dry before freezing. To ensure they are completely dry, lay them out on a paper towel or a cloth before freezing.
Some berries, such as raspberries and black raspberries, are very delicate, so you may want to avoid washing them before freezing. Blueberries, in particular, have a natural protective wax coating, so it's best to freeze them without washing so that their coating stays intact. This protective coating also prevents the blueberries from growing bacteria and getting freezer burn.
If you do decide to wash your berries before freezing, it is best to freeze them on a cookie sheet, baking sheet, or tray first to ensure they freeze individually rather than in a giant lump. Once the berries are frozen, you can transfer them to a glass jar or an airtight stainless steel container.
Make sure to label the berries as unwashed or washed and dried before freezing, so you know whether to wash them before use. It is also a good idea to mark the date you froze the berries on the container.
