Equipment Needed
- Mixing bowls
- Baking dish
- Parchment paper
How to Make This Recipe
Step 1 – Preheat the Oven
Start by preheating your oven to 350°F (175°C). Position a rack in the lower third of the oven and line a baking sheet with parchment paper. This will help with cleanup and catch any drips.
Step 2 – Prepare the Blueberries
In a large mixing bowl, combine the blueberries, sugar, cornstarch, lemon juice, and salt. Gently toss everything together until the blueberries are well-coated. Once ready, transfer the mixture to your prepared baking dish, spreading it evenly across the bottom.
Step 3 – Make the Crumble Topping
In another bowl, mix together the almond flour, oats, oat flour, tapioca flour, brown sugar, cinnamon, and salt. Pour in the melted butter and stir until the mixture forms clumps. This will create the delicious crumble topping. Crumble it evenly over the blueberry layer in your baking dish.
Step 4 – Bake and Serve
Place the baking dish in the oven and bake for about 40-60 minutes, or until the filling is bubbling and the topping is golden brown. Keep an eye on it to ensure it doesn’t burn. Once done, let it cool slightly before serving. Enjoy your blueberry crisp warm, preferably with a scoop of vanilla ice cream on the side.

Tips for Perfect Results
To ensure your blueberry crisp turns out perfectly, consider the following:
- Make sure the blueberries are fresh or properly thawed if using frozen.
- Allow the crisp to cool for at least 10 minutes before serving; this helps the filling thicken up a bit.
- If the topping browns too quickly, lightly cover it with foil while baking.
- For extra flavor, add a pinch of nutmeg to the crumble mixture.
Flavor Variations
Feel free to switch things up with these simple flavor variations:
- Add a handful of chopped nuts to the crumble for added crunch.
- Use a mix of berries for a different taste; raspberries and blackberries work great.
- Spice it up with a touch of ginger mixed into the blueberry layer.
What to Serve With This Recipe
This blueberry crisp pairs wonderfully with several options. Consider these serving suggestions:
- Vanilla ice cream: A classic complement that adds creaminess.
- Whipped cream: Light and fluffy, it’s a great way to lighten the dessert.
- Yogurt: A scoop of plain or flavored yogurt can add a tangy contrast.
Storage, Make-Ahead & Leftovers
You can store leftover blueberry crisp covered in the fridge for up to 3 days. If you want to make it ahead of time, you can prepare the topping and fruit mixture separately and assemble them just before baking. It can also be frozen for up to 3 months in an airtight container. To reheat, bake in a preheated oven at 350°F until warmed through.
