Blueberry Crisp

Here is a cozy, golden Blueberry Crisp dessert bursting with fresh fruit flavor that tastes insanely wonderful. This dessert filling is thick and juicy with fresh blueberry flavor. Serve warm with a scoop of dairy free ice cream. Allow the ice cream to melt just a bit to make for the perfect warm and cold fruit dessert combination.

Use fresh blueberries from your garden, local farmer's market, or grocery store to throw this recipe together in just a matter of minutes!

This recipe doubles as an after dinner dessert or a midmorning brunch dish. And enjoy this warm, fruit dish at special occasions such as baby showers and family BBQ's.

This crisp has two ingredient components-- the blueberry filling and the crisp topping. Here are the ingredients you'll need (most of them you already have on hand) to bake this mouthwatering dessert.

blueberry crisp ingredients and baking utensils

  • fresh blueberries-- 6 cups, stem removed, rinsed and dried
  • cornstarch-- or arrowroot powder works too
  • granulated sugar
  • vanilla extract
  • fresh lemon juice--plan to use about half of one lemon. We use this citrus juicer to extract the juice easily. Fresh lemon juice always tastes best
  • kosher salt
  • gluten free old-fashioned rolled oats-- our go-to brand is this certified gluten free Bob's Red Mill sealable bag
  • gluten free all-purpose flour-- by spoon, scoop the flour into the dry measuring cup. Level with a knife, known as the "scoop and level" method. Filling the measuring cup by plunging it into the flour bag and lifting it out will add extra flour to your recipe; sometimes as much as ¼ cup extra for every cup. We like using Bob's Red Mill Gluten Free 1 to 1 Baking Mix for this recipe. We buy it in bulk here to save money.
  • brown sugar-- packed
  • baking soda-- this loses its potency after the container has been opened for 6 months. Consider labeling your container when you open it.
  • baking powder-- same tip as above
  • ground cinnamon-- always double check your ground spices are gluten free. We use this brand.
  • dairy free butter-- Earth Balance Buttery sticks are our favorite. The red box is soy free and vegan.
  • optional-- So Delicious Cocowhip or So Delicious dairy free vanilla ice cream
  • pastry blender-- this is a must-have kitchen gadget for crisps and pies; we use ours often
  • 9 x 9-inch baking dish-- we use our dish almost daily in the kitchen for our dinner recipes and desserts

are old-fashioned oats gluten free

While old-fashioned oats are naturally gluten free, they are known to become cross-contaminated with gluten during the harvesting and manufacturing process. If you are gluten free, you will want to use certified gluten free oats for this recipe.

We use Bob's Red Mill certified gluten free old-fashioned rolled oats in all our recipes that call for old-fashioned rolled oats.

how does blueberry crisp thicken

Adding cornstarch or arrowroot powder perfectly thickens up the blueberry filling in this recipe. When baking, be sure the filling is bubbling-hot to ensure the cornstarch is cooked enough to thicken the filling.

what enhances the flavor of blueberries

Just a tiny amount—a squeeze of fresh lemon--enhances the berries' fruity flavor, much the same way vanilla extract complements chocolate. In this recipe you don't even taste the small amount of fresh lemon in the finished dessert, but it will add depth of flavor and complexity.

should I refrigerate a baked blueberry crisp

Nope! Just cover it with a lid, foil or plastic wrap and keep it on your countertop for up to 2 days.

what to do with leftovers

While Blueberry Crisp leftovers are rarely a thing in our home, when it does happen they're consumed at breakfast the following morning. These make for the best leftovers at breakfast too!

When leftovers happen, cover the baking dish and place on the countertop up to 2 days. Reheat leftovers in the microwave when ready to enjoy.
