This Apple Blueberry Crisp is a warm and fruity dessert that brings joy to any table! With juicy apples and sweet blueberries topped with a crunchy oat mixture, it’s hard to resist.
Whenever I make this, the house smells amazing! I love serving it with a scoop of ice cream on the side. Who can say no to warm fruit and cold cream? Yum! 🍦
Key Ingredients & Substitutions
Apples: Use any variety you like! I recommend a mix of tart and sweet, like Granny Smith and Honeycrisp. If you don’t have fresh apples, you can use canned or frozen, but adjust the sugar since they might already be sweetened.
Blueberries: Fresh blueberries are fantastic, but you can substitute with frozen blueberries if they’re out of season. Don’t thaw them before adding to the mixture; just toss them in frozen to keep the filling from getting too watery.
Sugars: Granulated sugar and light brown sugar work well, but if you’re looking for a healthier option, consider using coconut sugar or maple syrup. Just remember to adjust the amounts as needed!
Oats: Old-fashioned oats give great texture. If gluten is a concern, use certified gluten-free oats or swap them for crushed nuts or almond meal for a nutty twist.
How Do I Ensure My Crisp Topping is Perfect?
Getting the crisp topping just right adds a special crunch to the dish. Here’s how to nail it:
- Use cold butter to achieve a flaky texture. Cut it into small pieces and mix quickly. Don’t overwork the mixture!
- Ensure you’ve got a mix of fine and larger crumb sizes; this adds interest and crunch.
- Spread the topping evenly, but don’t press it down too tightly. This helps create a nice, crunchy top!
When you pull it out of the oven, it should be golden brown and bubbly around the edges. Let it cool slightly before serving—the filling thickens a bit and the flavors meld beautifully!

How Much Time Will You Need?
This recipe takes about 15 minutes to prep and around 40-45 minutes to bake. You’ll have a delicious warm dessert ready in about an hour! Just enough time to set the table and get your ice cream ready!
Step-by-Step Instructions:
1. Preheat and Prepare:
Start by preheating your oven to 350°F (175°C). Grab a 9-inch round baking dish and give it a light greasing with butter or non-stick spray to prevent sticking.
2. Make the Fruit Filling:
In a large mixing bowl, combine your sliced apples and fresh blueberries. Add the granulated sugar, 2 tablespoons of flour, lemon juice, cinnamon, nutmeg, and salt. Gently toss everything together so that the fruit is nicely coated with the mixture.
3. Assemble the Dish:
Now, transfer that gorgeous fruit mixture into your prepared baking dish, spreading it out evenly so every bite will have a mix of apples and blueberries.
4. Prepare the Crisp Topping:
In another mixing bowl, combine the rolled oats, ¾ cup flour, brown sugar, cinnamon, and salt. Stir to blend them together. Then, add the cold butter cubes to this mixture. Using a pastry cutter, two forks, or your fingers, mix until the mixture looks like coarse crumbs with some larger pea-sized pieces.
5. Add the Topping:
Sprinkle the crisp topping evenly over the fruit in the baking dish. This will give you that lovely crunchy texture once it’s baked!
6. Bake It Up:
Put the baking dish in the preheated oven and bake for 40-45 minutes. Keep an eye on it; you’re looking for the fruit to be bubbly and the top to turn a beautiful golden-brown color.
7. Let It Cool and Serve:
When done, remove the dish from the oven and let it sit for a few minutes to cool slightly. If you like, dust the top with a bit of powdered sugar for a pretty finish!
8. Enjoy!
Serve your Apple Blueberry Crisp warm, with a scoop of vanilla ice cream or a dollop of whipped cream on top for that extra special touch. Enjoy every delicious bite!
Happy baking!

Can I Use Different Fruits in This Crisp?
Absolutely! You can mix and match fruits based on your preference and what’s in season. Peaches, cherries, or raspberries work wonderfully alongside apples. Just keep the overall volume the same!
Can I Make This Crisp Gluten-Free?
Yes, you can! Simply replace the all-purpose flour with a gluten-free flour blend and ensure your oats are certified gluten-free. The taste and texture will remain delicious!
How Should I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, pop it in the oven at 350°F (175°C) for about 10-15 minutes or until warmed through.
Can I Prepare the Crisp Ahead of Time?
Yes! You can prepare the fruit filling and topping separately, storing them in the fridge for up to a day. When you’re ready to bake, just assemble and cook as directed!
