    Why you will love this recipe

    Gluten-free blueberry crisp is one of our favorite desserts to serve in the spring and summer when blueberries are in season and at their freshest. This crisp has a sweet jammy blueberry filling that is bursting with flavor, and the buttery oat crumble topping has the perfect amount of crunch. You can bake this dessert in a 9×13″-inch baking dish which is great for travel, or in individual ramekins for a more personalized look. Don't forget to top it off with a scoop of vanilla ice cream.

    • Easy and straightforward - With only 10 minutes to prep and just 30-45 minutes of baking time, this delicious dessert can be made in under an hour from start to finish.
    • Simple healthy ingredients - It's summer served in a dish. This easy recipe has so much flavor and uses very simple ingredients with no refined sugar.
    • Beautiful rustic presentation - You'll get a rustic bakery-style look with minimal effort. My favorite way to serve this recipe is in mini ramekins for a more personalized feel.

    Gluten-Free Blueberry Crisp Ingredients

    Ingredient Notes

    • Gluten-Free Oats: Oats are a key ingredient in this recipe. We prefer rolled oats for added texture, but quick oats will work too. If avoiding gluten, make sure to look for certified gluten-free oats.
    • Almond Flour: Instead of gluten-free all-purpose flour we use almond flour which has a finer texture.
    • Sliced Almonds: The sliced almonds add a bit of crunch to the topping.
    • Butter: Melted butter gives this topping a rich buttery crisp flavor that is so good! For vegan/dairy-free options, use melted coconut oil or vegan butter as a substitute.
    • Coconut Sugar: To keep this recipe without refined sugar, we use coconut sugar. You can also use brown sugar.
    • Vanilla Extract: Use a high-quality vanilla extract for the best results.
    • Salt: A pinch of salt helps bring out the sweetness and balance the flavors.
    • Cinnamon, optional: Cinnamon adds a warm, cozy flavor to the crisp topping. I prefer to leave it out but my husband loves the addition.
    • Blueberries: Plump juicy fresh blueberries are the foundation of this dessert. You can use fresh or frozen blueberries. If using frozen berries, do not thaw.
    • Maple Syrup: For a touch of natural sweetness we add pure maple syrup.
    • Arrowroot Powder: This helps the blueberry filling to thicken. If you do not have arrowroot starch you can use cornstarch or tapioca starch instead.
    • Vanilla Extract: The vanilla extract helps enhance the flavor of the filling.
    • Lemon Juice and Lemon Zest: To complement the flavor of the blueberries, we use fresh lemon juice and lemon zest.

    How To Make Gluten-Free Blueberry Crisp

    A grid of four different step by step photos for blueberry crisp. First photo shows blueberries in a clear bowl with  blueberry filling. Second photos shows blueberry filling poured into a white 9x13 ceramic baking dish. Third photo shows oat crumble topping. Fourth photo shows crumble topping over the top of blueberry filling in 9x13 pan.

    Preheat the oven & grease your baking dish. Preheat oven to 350 degrees Fahrenheit. Grease a 9x13-inch baking dish or eight 8-ounce ramekins and set aside.

    1. Make the blueberry filling. Mix the blueberry-filling ingredients in a large mixing bowl. Pour the filling into the prepared baking dish.
    2. Make the almond oat topping. Using the same bowl that has been cleaned and dried, melt the butter in the microwave then add the vanilla extract. Add the remaining dry ingredients, then stir together.
    3. Sprinkle the oat topping over the blueberry filling. Distribute the crisp topping evenly over the blueberry filling. 
    4. Bake the crisp. Place the dish in the oven to bake for 35-40 minutes, or until the top is golden brown and the fruit is bubbling around the edges. Remove from the oven and let the crisp rest for 5 minutes, then serve with a dollop of ice cream.

    * If using ramekins- fill ¾ full with blueberry filling and sprinkle on the crisp topping. Place the filled ramekins on a baking tray and into the oven for 30 minutes. *

    Variations

    • Brown butter - Browning the butter for the crisp topping would be a rich decadent treat.
    • Dairy-Free/ Vegan - To make this recipe dairy-free and vegan, I recommend using coconut oil in place of butter for the crisp topping.
    • Add a fruit combination - Use can use half peaches and half blueberries, or blueberries and mixed berries for a delicious combination.

    Storage

    • To Store: Place any leftover blueberry crisp in the fridge, covered, for up to 3 days. You can also transfer it to a glass airtight container.
    • To Reheat: Individual portions can be reheated in the microwave, or place the entire pan in a 350 degrees Fahrenheit oven for 10-15 minutes or until warmed through.

    Top tip

    Make sure your oats are gluten-free! Our favorite brand of gluten-free oats is Bob's Red Mill Old Fashioned Rolled Oats.

    FAQ

    What is the difference between a crisp and a crumble?

    Fruit crisps and crumbles are often used interchangeably, but traditionally crisps have oats while crumbles have a flour streusel topping.

    Can I make this gluten-free blueberry crisp recipe dairy-free?

    This recipe can easily be made dairy-free by using melted coconut oil instead of butter in the crisp topping.

    Can I double this recipe?

    You can double this recipe in the same 9x13-inch baking dish and bake 5-10 minutes longer as needed.

    When are blueberries in season?

    Depending on where you live, blueberry harvest runs from April to late September.

      This recipe is perfection. Cooking with multiple food allergies can be challenging but Rebecca’s recipes make it so much easier. Just finished eating my second helping of this amazing dessert! Thankful for the added tip to sub half blueberries with peaches. I used white peaches and it turned out absolutely delicious!! Highly recommend!
