Low-Sugar Blueberry Peach Crumble
This Blueberry Peach Crumble features a gooey fruit center and a crisp crumble topping. Sweet and satisfying, it’s perfect for a crowd and the best way to use up your summer produce!
We won’t lie to you, this recipe was the result of a little kitchen experiment after we found ourselves with way more fruit than we knew what to do with. A play on classic summer peach crisps and crumbles, it features a sweet center and a rich, crispy topping. With the first bite, we knew it was a winner, and now we make it every year!
It’s the perfect way to use your summer fruit, and it’s always a hit with crowds. Plus, it combines just a handful of ingredients, most of which you probably already have on hand. And from start to finish, the whole thing only takes 45 minutes!
Even better, it’s super low in sugar, meaning it’s basically fresh fruit topped with granola. That sounds pretty dang healthy to us. So, we’d be lying if we said we don’t serve it for breakfast. It’s such a fun way to feel like you’re eating a treat, but it’s secretly full of nutrients and fiber. Top it with Greek yogurt, and you’ve got a balanced meal! Honestly, no matter how or when you serve it you really can’t go wrong!
Ingredients You’ll Need
Below is an overview of the ingredients and instructions to make this recipe. Be sure to scroll to the recipe card at the bottom of the post for the complete details!
- Peaches – For the best taste and texture, look for peaches that are solid in color, free from bruises or discoloration, and have a strong peachy aroma. They should also be firm but give just slightly when squeezed!
- Blueberries – Fresh blueberries are best. However, if needed, frozen options will also work.
- Lemon – We’re using both lemon juice and lemon zest to balance the sweet flavor of the filling.
- Cornstarch – This helps thicken the filling, preventing it from becoming soupy.
- Old-Fashioned Rolled Oats – We do not recommend using steel cut or quick oats for this crumble. If needed, look for oats that are certified gluten-free.
- Flour – This contributes to the crumbly consistency. Again, if you need this dish to be gluten-free, use a 1:1 all-purpose gluten-free flour.
- Sweetener – We use monk fruit sweetener to keep this blueberry peach crumble super low in sugar, but granulated sugar will also work.
- Sea Salt – Just a pinch helps enhance the flavor of the rest of the ingredients!
- Butter – Unsalted butter works best. However, if salted butter is all you have on hand just reduce or omit the extra salt.
How to Make the BEST Blueberry Peach Crumble Recipe
- Prepare. Before you begin, preheat your oven to 375 degrees Fahrenheit. Then, grease the bottom and sides of a 9×13 glass baking dish with cooking spray.
- Create the filling. In a large bowl, gently mix the peaches, blueberries, lemon juice, lemon zest, and cornstarch. Be careful not to smash the fruit! Then, transfer the fruit mixture into the prepared pan, and set it aside.
- Make the topping. In a separate, medium-sized bowl, add the rolled oats, flour, sugar, and salt, whisking to combine.
- Add the butter. Next, use a pastry cutter or your hands to cut the butter into the mixture. You should have a crumbly, sand-like texture! Sprinkle the crumble mixture evenly over the fruit.
- Bake. Transfer the dish to the oven, and bake until the top is slightly browned and the juices from the fruit are bubbling. Allow the dessert to cool slightly before serving, and enjoy!
Common Questions
We love to serve this recipe warm topped with a scoop of vanilla ice cream or whipped cream! However, if you want to enjoy it for breakfast, Greek yogurt works well, too.
Once cooled, you can cover the dish with foil. Or, transfer the crumble to an airtight container. It will stay fresh in the fridge for up to 5 days!
We don’t recommend freezing this recipe, because it doesn’t tend to thaw well.

#nailedit 😉 Yes, it is sweet, but not too sweet! Perfect if I do say so myself! Can’t wait for you to try it!
Oh my, I must try this!! (Although it makes me laugh that you were sitting on this recipe for a year, lolol!). It would work just the same with frozen fruit, right? I haven’t had a crumble in ages!! My favorite part is the topping…I could eat it all day and all night. I like your coconut sugar tip. Fruit+coconut sugar =health food. 🙂 Thanks for sharing at the Family Joy linkup and sorry for the long response, lol!
No need to apologize for you a lengthy comment! I love it 🙂 Yes, frozen fruit would work just as well. I may thaw it in a colander to let some of the extra moisture drain before assembling the crumble. Enjoy this delicious recipe…especially the topping! 😉
Blueberries and peaches really make a great combo – 1/2 the sugar is always great! It really is a super delicious dessert! Pinning and stumbling!
