Lemon blueberry filling
- 2 pounds blueberries (that’s 32 ounces, which is about 5 cups or a little less than 3 pints), fresh or frozen*
- ⅓ cup maple syrup or honey
- 2 tablespoons arrowroot starch or 3 tablespoons cornstarch
- ½ teaspoon lemon zest (less than 1 small lemon, zested—scale back to ¼ teaspoon zest if you don’t love lemon)
- 2 tablespoons lemon juice (from 1 to 2 lemons)
- ¼ teaspoon cinnamon
Gluten-free oat and almond topping
1 cup old-fashioned oats (certified gluten-free for a gluten-free crisp)
- ½ cup packed almond meal or almond flour
- ½ cup sliced almonds
- ⅓ cup lightly packed brown sugar
- ¼ teaspoon fine grain sea salt
- 4 tablespoons butter, melted
- 3 tablespoons plain yogurt (Greek or regular), or additional melted butter
- Preheat the oven to 350 degrees Fahrenheit. Rinse and drain the blueberries and pick through them to remove any stems still attached. In a 9 by 9-inch baking dish, mix together the blueberries, maple syrup or honey, arrowroot or cornstarch, lemon zest, lemon juice and cinnamon.
- In a medium mixing bowl, stir together the oats, almond meal/flour, sliced almonds, brown sugar and salt. Mix in the butter and yogurt. Stir until all of the flour is incorporated and the mixture is moistened throughout.
- Dollop spoonfuls of the oat mixture over the filling and use your fingers to break up the mixture until it is evenly distributed (no need to pack it down).
- Bake for 40 to 50 minutes, or until the filling is actively bubbling around the edges and the top is lightly golden. Let the crisp rest for 5 to 10 minutes before serving. Serve with vanilla ice cream (I insist!).
