Quick and Easy Blueberry Crisp is bursting with sweet, juicy blueberries and a crunchy oat topping. This easy fruit crisp recipe is perfect served warm from the oven topped with a scoop of vanilla ice cream. The easiest dessert recipe EVER!
The BEST Blueberry Crisp!
Fruit crisps are one of my all-time favorite desserts. Who can resist that bubbling, juicy, syrupy fruit topped with the MOST AMAZING crumble topping?
I’ve tried countless recipes and proportions to get the perfect crisp topping and THIS IS IT!
The perfect crisp topping should be crunchy and crispy. It should hold together in yummy, chunky clusters and should never ever be powdery and dry.
The fruit should be lightly sweetened – just enough so that it isn’t sour, but still keeping a bright and tart flavor that perfectly complements the sweet crumble topping.
The fruit should be perfectly thickened. It should be a syrupy sauce that clings to the berries. Not so thin that it’s watery and not so thick that it gets gummy.
Blueberry Crisp vs Blueberry Crumble
Crisps and crumbles are both dishes of baked fruit with a streusel crumb topping. Traditionally, while a crumb topping would be made of butter, flour, and sugar, a crisp topping would also include oats and/or nuts. The oats will crisp up during baking, while crumble toppings stay more dense and cakey.
As time has gone by, the lines have blurred and the names crumble and crisp are now often used interchangeably.
What kind of oats for Blueberry Crisp dessert
I use old-fashioned rolled oats for the crumble topping. It makes a chunkier, chewier, crispier streusel topping.
Ingredients for Blueberry Crisp
- Blueberries – I’ve used fresh, but you can also use frozen. No need to thaw first. I’ve made the proportions for this recipe with a 24 ounce container which is the size I find at my local grocer.
- Sugar – to lightly sweeten.
- Flour – to thicken.
- Cinnamon – just a touch for a cozy flavor.
- Lemon juice and zest – adds a bright flavor. The zest is optional but lemon and blueberries are ❤❤❤.
- Salt – just a pinch brings out the sweet flavor.
For the crumble topping:
- Brown sugar – for that sweet, caramely flavor
- All-purpose flour – to form the crumbles
- Old-fashioned rolled oats – crunchy and chewy crumbles
- Softened butter – to hold it all together in crunchy chunks
How to make Easy Blueberry Crumble
Blueberry Crisp has to be the easiest dessert to make EVER!
- Toss the berries in flour and sugar
- Mix the crumble topping and sprinkle on the berries
How to make Blueberry Crisp – Step by step
Prepare the berries
Toss the berries with the flour, sugar, cinnamon, salt, lemon juice, and lemon zest. Put in a baking dish.
Make the crumble topping
I get the best results by mixing the crumble topping by hand. Use softened but still cool butter. Combine all of the topping ingredients in a bowl and press the mixture together between your fingers until it is mixed and forming clusters.
If you have any problem forming the clusters, just stick it in the fridge for a few minutes to firm up.
Sprinkle the topping on top of the berries and bake
How long do you cook Blueberry Crisp?
Bake Blueberry Crumble until the berries are bubbly, and the topping is golden brown, about 35-40 minutes. If the topping browns too quickly before the berries are done, cover with a piece of tented foil.
What size baking dish to use for Blueberry Crumble
I used an 8 by 12-inch oval baking dish. You can also use:
- 8 by 8-inch pan
- 9 by 9-inch pan
- Pie dish
- 7 by 11-inch pan
- Any baking dish that holds about 2 quarts (8 cups)
- 6 ramekins (8oz each) for individual servings
It’s a good idea to put a baking sheet under your dish when baking to catch any drips, especially if your filling comes up to the top of the dish.
