    This gluten-free, fresh, easy raspberry sauce recipe is popular both in the summer and the winter. If you're making this raspberry sauce in the winter, you can even use fresh raspberries!

    This recipe was inspired by my victorian sponge cake recipe and pairs well on a dessert table with my homemade chocolate bars.

    • Frozen raspberries
    • Granulated sugar
    • Grapefruit, lemon, lime, or orange

    • In a separate bowl, combine water and cornstarch. Stir to combine. Mixing the cornstarch water first helps the corn starch to completely mix in.

    • Pour the cornstarch and water mixture into the frozen raspberry mixture and stir to combine.

    • Microwave the mixture on high for five minutes.
    • Carefully remove the bowl from the microwave and stir. The consistency should be thick like jam.
    • Enjoy hot or cold.

    Hint: Do not just toss the cornstarch into the raspberry mixture or you'll get little cornstarch clumps in the sauce. Mixing the cornstarch water first helps the corn starch to completely mix in. I like to use this mini whisk to ensure the mixture is combined.

    Substitutions

    • Frozen raspberries - instead of frozen raspberries, you can use fresh raspberries.
    • Granulated Sugar - cut the sugar down to one tablespoon for a sour, low-sugar sauce.
    • Citrus - you can choose any citrus you have on hand.

    Variations

    • Low sugar - decrease the sugar to one tablespoon for a low sugar option. You can also replace the sugar with a tablespoon of honey or agave.
    • Blueberry sauce - use frozen blueberries instead of frozen raspberries.
    • Seedless raspberry sauce - after taking the sauce out of the microwave, pour it into a mesh strainer placed over a large bowl. Then, gently press the sauce through the mesh strainer until all the seeds are filtered out.

    Serving Suggestions

    Try spreading this sauce on muffins, scones, and toast. Or, use it in other dessert recipes like on a chocolate cake. This recipe is also a great raspberry sauce for pancakes. Or, try this recipe for a raspberry dipping sauce. And, of course, this raspberry sauce would be delicious with ice cream.

    FAQ

    How much raspberry sauce does this recipe make?

    This recipe makes about two cups of raspberry sauce.

    Can I make the raspberry sauce on the stove?

    Yes! You can follow this recipe and bring the sauce to a boil on the stove using medium heat instead of placing it in the microwave. 

    What can I serve with raspberry sauce?

    I recommend pairing this sauce with my raspberry and chocolate cake recipe. You can also spread this jam on toast, scones, and muffins.

    Do I need to add citrus juice to the raspberry sauce?

    You don't have to add citrus juice to the raspberry sauce. Citrus is used to cut the sweetness, but it is not necessary.

    Can I make this raspberry sauce sugar-free?

    You can make a sugar-free raspberry sauce using this recipe. Just omit the sugar completely and you're all set.

    Equipment

    • Microwave-safe bowls - it's essential to use a microwave-safe bowl for this recipe. Click HERE to find my absolute favorite set of glass mixing bowls.
    • Mini whisk - use a mini whisk to really mix the cornstarch mixture so there are no lumps or clumps. Find my favorite one HERE.
    • A rubber spatula - is essential for mixing the sauce. Find my favorite one HERE.

    Storage

    This raspberry sauce can be made up to 1 week in advance and stored in an airtight container in the fridge. It can also freeze well for up to 6 months in the freezer.

    To thaw frozen raspberry sauce, place the container in a bowl of hot water for 15 minutes.

    Top tip

    For a low-sugar option, swap out the granulated sugar for honey or agave.

      Can I use this as a pie filling in a graham cracker crust? (The crust is baked separately before filling is added.)
