Blueberry Peach Crumble

Blueberry Peach Crumble is a cozy, easy dessert made with juicy fruit and a buttery oat topping. Perfect for summer or year-round with fresh or frozen fruit!

This rustic, homespun dessert takes two of the most loved summer fruits—blueberries and peaches—and turns them into something magical. They’re tossed with just a touch of sugar and lemon to enhance their natural sweetness, then topped with a buttery, golden crumble that crisps up beautifully in the oven. There’s no pie crust, no dough to roll out, no stress. Just wholesome, simple ingredients coming together in a warm dish of goodness.

Why You’ll Love This Recipe

Let’s break it down. Blueberry Peach Crumble checks all the right boxes—and then some.

First, it’s incredibly easy to make. We’re talking one bowl for the filling, one for the topping, and one baking dish. That’s it. No complicated steps, no chilling or kneading—just mix, layer, and bake.

Second, the flavor is off the charts. The combination of sweet, juicy peaches and tart blueberries is balanced perfectly with a hint of lemon and cinnamon. And the topping? Buttery, golden, and packed with just enough oats to make you feel like you’re doing something healthy (even if you’re not).

And don’t get us started on the texture—soft, syrupy fruit underneath a crispy, crumbly crust. Each bite is a perfect contrast of tender and crunchy, sweet and spiced.

This recipe is also:

• Naturally vegetarian
• Easily adaptable to gluten-free or vegan diets
• Ideal for make-ahead or serving a crowd
• Works with fresh or frozen fruit

Bottom line? It’s your new go-to dessert for everything from summer barbecues to cozy Sunday baking sessions. Simple, nostalgic, and completely irresistible.

Instructions

1. Preheat the Oven

Set your oven to 375°F (190°C). Lightly grease a 9×9-inch or similar baking dish and set it aside.

2. Prepare the Fruit Layer

In a large bowl, combine sliced peaches, blueberries, sugar, cornstarch, lemon juice, cinnamon, and salt. Toss everything gently until the fruit is well-coated. Pour the mixture into your prepared baking dish and spread into an even layer.

Tip: If using frozen fruit, don’t thaw—just add an extra 5–10 minutes to the baking time.

3. Make the Crumble Topping

In a separate bowl, mix together flour, oats, brown sugar, cinnamon, and salt. Add the cold butter and use your fingers or a pastry cutter to blend it in until the mixture looks like coarse crumbs. You should still see small bits of butter—this is what makes the topping flaky and crisp.

4. Top the Fruit

Evenly sprinkle the crumble mixture over the fruit layer. Don’t press it down too much—you want those crumbly peaks to get crispy in the oven.

5. Bake

Bake uncovered for 35–40 minutes, or until the topping is golden brown and the fruit is bubbling around the edges. If the top starts browning too fast, cover loosely with foil halfway through.

6. Cool and Serve

Let the crumble cool for at least 10 minutes before serving. This helps the filling thicken up a bit more. Serve warm with ice cream, whipped cream, or plain—it’s amazing any way you dish it up.

FAQs

Can I use only frozen fruit?

Yes! You can use frozen peaches and blueberries straight from the freezer. No need to thaw—just add 5–7 extra minutes to the bake time.

What size dish should I use?

A 9×9-inch square dish or an 8×10-inch rectangular dish works great. You can also use a deep pie dish or medium casserole dish.

Can I make it in advance?

Yes! You can assemble the crumble ahead and refrigerate it for up to 6 hours. Bake it right before serving.

Can I reduce the sugar?

Absolutely. Reduce the sugar in the filling or topping by up to half, especially if using very ripe or sweet fruit.

How long does it keep?

Store leftovers in the fridge for up to 4 days. Reheat in the oven or microwave before serving.

Conclusion

Blueberry Peach Crumble is the ultimate easy dessert. It’s comforting, crowd-pleasing, and comes together with ingredients you probably already have in your pantry and freezer. It’s perfect for everything from a cozy night in to a casual gathering with friends. You can dress it up with ice cream or serve it plain and warm—it never fails to satisfy.

Once you try this recipe, you’ll want to make it again and again. And when summer fruit is in season, it’s practically a tradition waiting to happen.
