Easy Apple Blueberry Crumble

Reasons to Love this Blueberry Apple Crisp

• A fresh spin on a classic dessert. I love traditional apple crisp, but there’s something special about recipes like my pear apple crisp, blueberry crisp, and today’s blueberry apple crisp that bring fresh ingredients to the mix. Plus, look at that gorgeous, festive color!
• Easy to make. Unlike baking apple pie, preparing an apple crisp couldn’t be easier. There’s no need to fuss with a pastry crust, just layer the filling and topping into a pan and bake.
• Crumbly crisp topping. The oats crisp up during the baking process, but the topping on this apple blueberry crisp still has a bit of the dense, cakey texture of a classic crumble or cobbler, too. It’s the best of both worlds.

You’ll Need These Ingredients

This recipe is very straightforward. Below is a look at the ingredients you’ll need for the apple blueberry filling and for the oat crumble on top. Each component requires less than 5 ingredients and you most likely already have them on hand! Scroll to the recipe card for the printable ingredients list and measurements after the post.

• Apples – I like to bake with Granny Smith apples. You could also use Gala or Honeycrisp if you’d like.
• Blueberries – Fresh blueberries are best, but frozen will also work in this recipe. Frozen blueberries can make the crumble more watery, so I recommend adding another tablespoon of flour to the filling mixture.
• Cinnamon – You could also use nutmeg or apple pie spice.
• Flour – I use 1:1 gluten free baking flour. You’ll need it for both the filling and the crumble. Feel free to use equal parts all-purpose flour instead if you’re not making a gluten-free apple crisp.
• Honey – Adds a hint of sweet to the apple filling. You could also use maple syrup or brown sugar.
• Lemon – Fresh lemon juice cuts through the sweetness. Bottled lemon juice will work in a pinch, but fresh will have better flavor.
• Oats – The best oats for crisps and crumbles are old-fashioned rolled oats. Quick oats are fine here, too. I don’t recommend instant oats, however, as they’ll turn out soggy.
• Brown Sugar – You can also use granulated sugar in the topping.
• Butter – I always use unsalted butter so I can control the salt content in my desserts. Make sure the butter is cold from the fridge.

How to Make Apple Blueberry Crisp

The steps to make this dessert are super simple and you’ll be rewarded with a bubbly, golden-baked apple crisp loaded with blueberries in an hour or less.

• Prepare for baking. Preheat your oven to 350°F. Meanwhile, grease a 9″x9″ baking dish or 11″ oven-proof skillet with cooking spray.
• Make the filling. Slice the apples and add them to a bowl with the blueberries, flour, honey, lemon juice, cinnamon, and salt. Gently toss so the fruit is evenly coated. Pour the mixture into your prepared baking dish.

• Make the oat topping. Next, combine the oats, flour, brown sugar, cinnamon, salt, and cold butter. Using your hands or a pastry cutter, cut the butter into the dry ingredients until pea-size crumbles start to form. Evenly sprinkle crumble topping on top of the fruit mixture.
• Bake. Bake this blueberry apple crisp at 350ºF for 35-45 minutes, until the top is lightly browned and the fruit filling is bubbly. Let the crisp rest for a few minutes, then serve it warm with ice cream.

Baking Tips

• Fresh is best. Always try to use fresh ingredients, like fresh blueberries and lemon juice, if you can find them.
• Use the right apple. I find that crisp-tart apples, like Granny Smith, hold their shape the best and don’t get mushy when baked. I use Granny Smith in most, if not all, of my baked apple desserts. Peeling is optional, but I will usually take the extra step to peel my apples as the peel can be tough and bitter to eat.
• Chill the butter. Just like making a pie crust, make sure the butter you use for your crisp crumble is COLD. You can even chill the butter in the freezer for 15 minutes. Cold butter yields a nice, browned crust.

What to Serve With Apple Crisp

Serve this apple blueberry crisp warm à la mode, with a scoop of vanilla ice cream. I also love it with this homemade raspberry frozen yogurt with pistachios for a little extra something something. It’s the perfect Thanksgiving dessert and I’ll even serve it at Christmas with eggnog or mulled wine after dinner.

How to Store and Reheat Leftovers

• Store the crisp airtight. Tightly cover the baking dish with plastic wrap. You can store leftover apple blueberry crisp on counter for up to 2 days or in the refrigerator for up to 5 days.
• Reheat. For a single serving, you can easily reheat this apple blueberry crisp in the microwave. Just place on a plate and warm up for 45 to 60 seconds. If you are reheating a whole crisp, I recommend heating oven to 350°F and baking for 10-15 minutes until warm.
