Can You Freeze Sunflower Seeds?

How to Freeze Sunflower Seeds

Sunflower seeds are a pantry essential and are perfect for adding to smoothies and salads. They contain vitamins and minerals that help you fight off viruses, so having a supply on hand is good for your health.

Whether you refrigerate or freeze them, sunflower seeds will be good for at least a year. 

To freeze them, simply add them to a freezer-safe bag. Leave around one inch in space at the top and press out as much air as possible before sealing the bag. Write today’s date and the use-by date on the front of the bag and place your sunflower seeds in the freezer. 

Given that nuts and seeds are often expensive, buying sunflower seeds in bulk and storing them in the freezer is a great way to save you money and given that they freeze so well, it’s something you should definitely consider.

3 Tips for Freezing Sunflower Seeds

Now you know how to freeze them, we’ve got our 3 top tips which we strongly recommend following when freezing sunflower seeds to have the best results:

Freeze OR Refrigerate
You can keep sunflower seeds for at least one year in the fridge or freezer, so it doesn’t matter where you store them. This is good to know if you’re short on freezer or fridge space and want to move your seeds from one location to another.

When stored in an airtight container at room temperature, sunflower seeds will be good for at least three months.

Keep Them Indefinitely
Sunflower seeds don’t actually go off. If you keep them in the fridge or freezer, they will be fine indefinitely. The reason we recommend using them within twelve months is that this timeframe ensures they will taste good and means your sunflower seeds retain all of their mineral and nutrient properties.

Use From Frozen
Whether you’re adding them to your morning smoothie or baking them into your signature cake, you can use sunflower seeds from frozen. This saves you a lot of preparation time in the kitchen and is another benefit of keeping your seeds in the freezer.

How Long Can You Freeze Sunflower Seeds?

You can freeze sunflower seeds for around twelve months. But as mentioned, sunflower seeds don’t really go off, and you can use them long after this.

Just be mindful that their taste will begin to deteriorate, and they may not be as rich in nutrients after this time.

Ultimately, a year is a long time to keep any type of food in the freezer, so you should be able to use up your sunflower seeds within this time.

How Do You Defrost Sunflower Seeds?

You don’t need to defrost sunflower seeds before adding them to smoothies, cakes, or other recipes.

However, if you’re using sunflower seeds as a snack or adding them to the top of your porridge, you can thaw them by transferring them from the freezer to the fridge.

You can also thaw sunflower seeds at room temperature if you prefer, and they should be ready to enjoy within a few hours of taking them out of the freezer.

Can You Refreeze Sunflower Seeds?

There’s nothing wrong with freezing sunflower seeds for a second time, providing you have thawed them in the fridge. Just be mindful that the more times you freeze and defrost any type of seed, you risk affecting its taste and texture due to the crystallisation process that occurs during freezing.

So, it’s best to store sunflower seeds in smaller portions, so you can easily take out whatever you need at any given time.

Do Sunflower Seeds Freeze Well?

Sunflower seeds freeze really well, and you can essentially keep them indefinitely in the freezer. That being said, it’s best to use sunflower seeds within twelve months, whether you’ve stored them in the fridge or freezer.

Overall, freezing sunflower seeds is a great way to preserve them long into the future and is a great solution if you’ve bought them in bulk.
