It’s got that perfect balance of juicy berries and a golden and buttery topping. Whether I’m baking it for summer get-togethers or a weeknight treat, this recipe always delivers warm, nostalgic comfort in every bite.

Easy Blueberry Crisp Recipes

Crisps are some of my favorite treats to make. Not just because they’re easy but because I’m a sucker for warm and fruit desserts. If I’m home alone and craving a cozy treat, I love making a quick, single-serving crisp with apples or whatever frozen fruit I have on hand. So simple and so satisfying! This blueberry crisp is a new favorite, especially during blueberry season. The filling gets jammy and sweet, the topping bakes up golden and buttery, and it’s perfect with a scoop of vanilla ice cream. Whether I’m serving it to guests or keeping it all to myself, it never lasts long!

Tips for Beginners

Use your hands. Working the cold, cubed butter into the flour with your fingers creates those perfect, buttery crumbs that make the topping extra crisp and golden. A pastry cutter works, too, but hands give you the most control.
Add lemon juice. If your blueberries are extra ripe or sweet, stir in an extra teaspoon of lemon juice to brighten things up and keep the flavors balanced.
Use frozen berries if needed. Sometimes I use frozen blueberries and just throw them right in! Use them straight from the freezer and add 5–7 minutes to the bake time. The crisp will still turn out beautifully bubbling and golden.

How to Store and Reheat

Store any leftovers covered in the fridge for up to 2-3 days for peak freshness.

You can also freeze the fully baked crisp once it’s completely cooled. Just wrap it tightly and freeze for up to 2 months.

To reheat, warm it in a 350°F oven until heated through. The microwave works too, but the topping may soften a bit.

If you’d like to make this ahead, you can assemble the crisp (unbaked) and refrigerate it for up to 24 hours before baking.

Serving Suggestions

I love serving this blueberry crisp warm with a big scoop of vanilla ice cream or a dollop of whipped cream . It’s a summer classic that’s also cozy enough for cooler months. Try it with a sprinkle of lemon zest or a drizzle of maple syrup for something extra.
