My mom and dad often would tell me stories of when they were growing up, one of their favorite things, was to go out in the garden and grab a stalk or two of rhubarb, and their moms would cut and clean them and then give them a bowl of sugar to dip the tart veggie in. It was one of their favorite memories. I didn’t grow up with the same nostalgia, so my memories are limited to my grandma’s strawberry rhubarb pie. I had actually never tasted fresh rhubarb before, so when we visited my mom recently and she had some fresh rhubarb growing in her yard that just happened to have come from the farm where she grew up, of course we had to try it! And, I decided to transform it into a delicous blueberry rhubarb crisp.

Prepare the Fruit Mixture

To make this recipe, you’ll need about two cups of chopped rhubarb. It’s important to make sure you only eat the stalk, as other parts of the plant can actually make you sick. Then add a little bit of sugar to the bowl of rhubarb and the bowl of blueberries and let them sit for a bit while you work on the crisp topping. After 10 minutes, drain any excess liquid from the rhubarb and blueberries. Combine the fruit in a large bowl and add cornstarch and vanilla, and mix until thoroughly combined.

How to Make a Gluten-Free Crisp Topping

To make the crisp topping, add almond flour, gluten-free rolled oats, monk fruit sweetener, cinnamon, and salt to a food processor. Then, add the diced butter, and pulse a few times until it creates a crumbly topping.

How to Make Blueberry Rhubarb Crisp

Pour the fruit mixture into a 8×8 pan, and top with the crumble mixture. Bake at 375°F for 40 minutes or until the topping begins to lightly brown. Let cool for a few minutes and serve. Or if you’re like me and prefer your crisps cold, let it cool completely then put it in the fridge to chill. Eat as-is or top with your favorite ice cream. Enjoy!
