Strawberry reduction is super easy to make. In a nutshell, you puree strawberries, add a little lemon, salt, and maybe some sugar, and reduce by half over low heat. I typically use it for my strawberry cake recipe, strawberry buttercream, or as a cake filling so I like mine to be a bit thicker.

Whats The Difference Between A Puree and A Reduction?

Strawberry reduction and strawberry puree are not the same thing. A puree is just blended strawberries and is mostly water. For baking we typically need the strawberry flavor to be more intense.

To make your strawberry puree thicker, you're going to want to simmer it for a few minutes. Simmering the mixture reduces the amount of moisture that is in the puree allowing for a stronger strawberry flavor with less liquid. 

The best thing about making a reduced strawberry puree is that it keeps all the flavor of the strawberries without adding extra moisture.

Strawberry Reduction Ingredients

I prefer to use frozen strawberries because frozen fruit is generally picked at the peak of freshness and then frozen. You get the most flavor in frozen strawberries.

If strawberries are in season though and you need to use them up, making puree is a great option. You can freeze leftover puree and defrost as you need it. If you're super talented and know how to can, you can make canned puree. This is definitely on my to-learn list.

When buying fresh strawberries, choose brightly colored, shiny berries that are dry, firm, and plump. They should still have fresh-looking green caps attached. Avoid soft, dull-looking, or shriveled berries. Since strawberries do not ripen after being picked, avoid berries that are partly white as that means they are unripe

How to make a strawberry reduction in 5 easy steps

  1. Defrost your strawberries or chop up your fresh strawberries.
  2. Blend your strawberries in a blender or give them a quick blend using an immersion blender. close up of strawberries in a blender
  3. Add the blended strawberries, sugar, lemon zest, and salt and bring it all to a simmer on medium heat.close up of strawberry reduction ingredients in a saucepan
  4. Reduce the heat to medium-low so it's just barely bubbling and allow the mixture to reduce (40-60 minutes). Stir occasionally to prevent burning. The reduction should look like tomato sauce, not watery. Close up of strawberry reduction on a spoon
  5. Let the strawberry reduction cool before using.

How to store the leftover strawberry reduction

You can store leftover strawberry reduction in the fridge for two days or you can freeze it up to 6 months. Fresh strawberries are very prone to mold so be sure to only leave cakes with fresh fruit fillings at room temperature for no more than 2 hours. Cakes with fresh fruit filling can be refrigerated for two days before consumption.

    Loved this. I made this strawberry reduction to flavor the white cake mix (made using your recipe to amp it up) for my son's wedding in May. Delicious! My brother-in-law made a strawberry filling to put between the layers and we iced the cake with buttercream frosting. (It ended up being a very small wedding due to COVID-19 and that's why I was making the cake.) We got loads of compliments. People saying it was the best wedding cake they had ever had. Thank you for the recipe!

    Wow!!! This stuff is amazing and totally addictive!! Not too sweet, just right. I used 32oz of fresh California strawberries. Took about 30ish minutes to reduce. Came out with 2 cups. Which is perfect because after using it n your strawberry cake it leaves me a 1/4 cup to enjoy on pancakes. Thank you for sharing and for including a video, it helped me know what the consistency should be.

      Just needs to be reduced a little bit more, you might need to turn up the heat a little if it seems like its taking too long

    Do you add the puree directly on the cake? If so does it soak into the cake? Should I add a layer of my buttercream and then the puree?

      Yes you add it directly to the cake and it soaks in, that's a good thing 🙂

    One more question, the recipe says to add the lemon zest and salt before cooking and then later in the recipe it says add the lemon zest and salt after reducing. Can you clarify that? I can't wait to try this recipe! Thanks!

    I want to make this for a cake on Saturday. I need to make the cake on Friday and then on Saturday it will probably be out for 3 or 4 hours before eating. I don't want to refrigerate it because I'll be covering it in fondant and an edible icing strip.
    So does this mean I'll need to skip the strawberry puree completely or does it last longer at room temperature if it's made from frozen berries? Thanks and thanks so much for your awesome videos. They've been a massive help.

      Fondant and edible images can go in the fridge. If you use fruit it will definitely have to be in the fridge or the strawberry will mold

    When you freeze and defrost, do you have to reduce on stove a little bit before use?

      I increased the amount of the recipe to make more puree so it's twice as big as the original.

    Is it possible to reduce this recipe too much. I kept reducing mine bc it did t seem thick enough and basically I think I ended up making strawberry jam but it’s that consistency of nearly jelly like and thinking I may have lost some flavor that way because it doesn’t seem as strong . Is this possible and if it is can you say how long you let yours boil first and what the ending consistency should be. Thanks.

      You could reduce it more, it's not going to hurt it 🙂

        Thanks so much. I am so excited because I remade this for my second time and didn’t reduce as much and my reduction looks identical to yours and berries full of flavor and extra ripe. I never liked fruit hot but I’m telling you I could have eaten that entire container of purée right off the stove.
