Easy Blueberry-Citrus Crisp

Easy Blueberry-Citrus Crisp

Blueberry-Crisp is a traditional, and quintessentially American dessert. Of course, the deep-blue color evokes images of the American flag. In addition, blueberries are native to North America and have been a part of indigenous and American cuisines for centuries.

This Easy Blueberry-Citrus Crisp is the perfect sweet treat to celebrate July 4th, or any other patriotic holiday! This particular recipe is also gluten-free. It incorporates everyday fridge and pantry ingredients, so it’s one of those desserts you can throw together in a pinch.

I love combining citrus and blueberries in desserts. In my opinion, blueberries can taste a little bit flat on their own. What I mean is that blueberries only have one flavor – sweet – especially when they are cooked. However, adding citrus brightens and elevates the flavor, as it balances the sweet blueberries with tart and sour notes. You can use oranges, as I did in this recipe, but lemon would be delicious, too! Make sure you use both the zest and juice of whatever citrus fruit you decide to use. (The best microplane for zesting citrus is this one — I use it almost everyday and it’s easy to clean, too!)

See the recipe below for this super simple and gluten-free Blueberry-Citrus Crisp! It’s especially delicious when topped with creamy vanilla ice-cream.
