How To Freeze Fresh Raspberries


Are you looking to learn how to freeze fresh raspberries? Then you’ve come to the right place.

Whether you’ve recently purchased the fresh raspberries from the store or grown them yourself in the garden, freezing raspberries is a great way of preserving them for use at a later date.

Tools & Equipment For Freezing Food

These are my tried and tested tools and equipment for freezing food.

Whether it’s fresh fruits or completely prepared meals these tools will make the process easier, and the food last longer and taste better!

Containers – We opt for glass containers as they are better for the environment, much higher quality and don’t stain like plastic, however they are an investment.

So if you’re short on money buy high-quality plastic containers in the meantime.

Just be sure that you buy your containers in a range of sizes as you’ll be using them to freeze and store a range of different foods.

Ziplock Bags – Invest in quality freezer bags and they’ll help keep out air, prevent frost and keep your food fresh for longer.

The majority of the high-quality ziplock bags come with a small area for you to write information about the food (i.e. what it is, when it was frozen and defrosting instructions) on the bag.

Ice Cube Trays – Ice cube trays can help you freeze more than just water. Instead, we use them for freezing small portions of food such as egg whites, tomato sauce, pesto etc.

Simply add the food to the tray, freeze and once frozen pop the food out and into a ziplock bag, then you can simply take one or two portions of food out and defrost as needed.

Foil Baking Containers – We use foil baking containers when we’re batch cooking frozen meals.

They are affordable, durable and come in a variety of sizes allowing you to portion out or put everything in one large container to be cooked at a later date.

If all that wasn’t enough, the majority of meals are safe to be cooked in the oven with the foil container. This reduces the amount of hassle, time and washing up you’ll have to do – winner!

How To Freeze Fresh Raspberries

We’ll begin by cleaning the raspberries. Unlike some other fruits, you won’t be able to run the raspberries under the tap as the pressure will damage them.

Instead, place the berries in a colander and then place the colander into a large bowl of water and swirl them around gently.

Then you can pull your colander out from the water and dangle it over the bowl of water until the water has fully drained.

Then lay a paper towel out on the counter and spread the berries out on top of them in a single layer.

Leave them to dry naturally at room temperature for 10 to 15 minutes.

In the meantime, grab a baking tray and line it with baking paper or wax paper.

Then once the raspberries are dry, move them over onto the baking tray, again in a single layer.

Once all the raspberries are on the tray, slowly move the tray into the freezer.

Flash freeze the raspberries in the freezer like this for between 4 and 12 hours or until they are fully frozen.

Once the raspberries are fully frozen remove the baking tray from the freezer and transfer the raspberries into a container.

This method prevents the raspberries from being frozen together and sticking together in the process which will ultimately damage them and make them more difficult to thaw.

In some cases, you may choose to add sugar to your raspberries prior to freezing. This is due to a lack of acid content, which leads to a decrease in the preservation of the fruit.

This isn’t strictly necessary with raspberries they freeze equally well with or without sugar.

If you decide to freeze your raspberries with sugar you’ll want to add three-quarters of a cup of sugar for every four cups of raspberries.

Frozen raspberries are good to keep in the freezer for up to one year.

How To Thaw Raspberries

There’s a number of ways you can choose to thaw raspberries depending on the amount of time you have and the way in which you plan to use them.

My favourite way is to slowly defrost the raspberries in the fridge as this preserves the flavour and texture of the berries significantly more when compared to other methods I discuss below.

To defrost raspberries in the refrigerator you’ll want to place the berries in a bowl or on a plate and leave them overnight (or for around 12 hours).

A slightly quicker method when it comes to defrosting raspberries is to leave them out to naturally defrost at room temperature. Again you’ll want to pop the frozen berries in a bowl or on a plate.

Then, simply leave the plate or bowl out on the counter.

How long it takes for the berries to defrost is going to depend on the temperature of your freezer and your home. However, a rough guide based on my experience is around an hour.

Finally, if you’re looking to thaw raspberries quickly then you can use a microwave.

To do so simply adjust the setting on your microwave to defrost. Then place the bowl or plate of raspberries in the microwave, and set the timer to 30 seconds.

Once the thirty seconds is up, check your raspberries.

You want them to look lightly covered in frost, feel free to try one or feel one to test whether or not they are still frozen.

If they are, repeat the process as many times as needed until the raspberries are fully defrosted.

This only works when the raspberries are put into the microwave in small batches (around 1 to 2 cups at a time) any more than this and you’ll risk overheating the raspberries on the top surface in order to try and defrost the ones below.
