This blueberry crisp is perfectly balanced with a juicy fruit filling and a crisp oat topping. Using cornstarch keeps the filling thick without becoming gummy. I also don't add lemon juice or other liquids to the filling. Trust me when I say you are going to have plenty of juice in those berries.
When it comes to seasoning, I wanted to make this gluten free crisp special. So I skipped the butter and opted for a high-quality olive oil and cardamon. A sophisticated twist. I don't recommend cinnamon as it overpowers the berry flavor, while cardamon enhances it.
Ingredient Notes
- Blueberries: Use fresh blueberries in the summer and frozen blueberries in the winter.
- Sugar: Honey is a delightful alternative in the filling but stick with plain regular white sugar in the crisp topping.
- Cornstarch: Thickens the fruit filling. Substitute it with tapioca or arrowroot starch.
- Oats: Be sure they are certified gluten-free and do not substitute oat flour.
- Almond Flour: You can also use gluten-free one-to-one gluten-free flour.
- Olive Oil: You can use olive oil, butter, or coconut oil in the crisp. But I prefer the flavor the olive oil adds to the berries.

Add the Filling Ingredients
No need to heat the filling first. Just combine in your greased pan.
Prepare Crisp Topping
Make sure the olive oil it well blended with the dry ingredients to the topping won't dry out during baking.
Spread the Crisp Topping
Crumble over the topping, and don't worry if you have spots of blueberry poking through.
Bake
The key to a perfect crisp is to bake it covered for half the time and then uncovered. This allows the berries to soften and the top to crisp up.
Recipe Tips
- Let the crisp rest for at least 15 minutes to help the filling set before serving.
- I recommend baking on a sheet pan to catch drips from the berry filling bubbling over.
