“A fantastic recipe! Made this for a cookout and folks were haggling for the last piece!” ~Bev

I was so happy with my recent Summer Jumble Fruit Crumble that I decided a pie version was in order. This formula can be applied to so many different kinds of fruits, and the combinations are endless. The formula goes like this: one frozen pie crust + fresh fruit + crumble topping. Peach and blueberry happens to be a fabulous combination, but you can mix and match the fruit to your heart’s content. How about raspberry with Italian plums or blackberries with nectarines? Carry this idea into fall with figs, pears, and apples. Make this blueberry peach crumble pie now and consider it a jumping off point for future pie creativity.

This is as easy as a crisp or crumble, but with a little more structure thanks to the crust. Toss your fruit with a little sugar, some lemon juice, and cornstarch in a big bowl and then pile it into the frozen crust (no need to thaw it.)Â Top everything with a simple crumble made with butter, flour, oats and sugar, then bake it up. It’s not rocket science, but it’s goooood.

The only thing left is to scoop out some vanilla ice cream, or add a dollop of whipped cream…creme fraiche or chantilly cream if you’re feeling fancy.

the Great Island kitchen recommends: Â Instant Clearjel
It’s a thickening agent that’s like cornstarch only much more effective. I’m planning to use it all summer long with my fruit pies, crisps, and crumbles. I was amazed at the results and I’m excited to bake with it this season. Btw, this isn’t sponsored, I’m just over the moon about it 🙂
tips for blueberry peach crumble pie
- Did you know you can make a big batch BULK crumble mix and stash it in the freezer for up to a year? It’s a fabulous way to enjoy simple fruit desserts all year long.
- Let the blueberry peach crumble pie cool completely if you want a neater cut. I think it’s better to dig right in, myself.

Easy Blueberry Peach Crumble Pie
Ingredients
- 1 frozen pie crust, do not thaw
- 2 cups sliced or chopped peaches, more if necessary to fill your pie crust
- 2 cups blueberries, more if necessary to fill your pie crust
- 2 Tbsp Instant Clear Gel, substitute cornstarch
- 1 Tbsp lemon juice
- 2 Tbsp sugar
crumble topping
- 1 cup flour
- 1/3 cup sugar
- 1/3 cup brown sugar
- 1/3 cup rolled oats
- 1/2 cup unsalted cold butter, cut in pieces
Instructions
- Set oven to 350F
- Toss the fruit in a large bowl with the cornstarch, lemon juice, and sugar. Let sit for 15 minutes to allow the juices to start to develop.
- Put the crumble ingredients in the bowl of a food processor and pulse until the mixture is crumbly.
- Sprinkle the topping all over the fruit and bake 50-60 minutes until the crust is browned and the fruit is bubbling.
- Let cool for neater cutting.
Notes
- I’ve been loving Marie Calendar’s frozen pie crusts lately. They come in a package of 2, so you can easily make another pie when you get the urge. (This isn’t sponsored, I just like them!)
- Add your favorite chopped nuts to the crumble.
- We love to eat the leftovers (if you have any) for breakfast. Just heat briefly in the microwave.

I made two of these at once giving one pair to my neighbor who pet sits for me. It serves better when it has sat over night. It was delicious and I can’t wait to make it again! So simple and easy to make and with staples from my shelves and fridge.
I’m so glad it was a hit Ginny 🙂
A fantastic recipe! Made this for a cookout and folks were haggling for the last piece! You have the best sight. Your recipes always have readily available ingredients and turn out perfect every time. Thank you so much. ?
Can I use 2 Tbs. cornstarch if I don’t find the Instant Clear Gel at my grocery. The pie looks amazing!
Yes, go ahead and use the cornstarch.
This recipe was easy, and really delightful to eat. It is light and I have enjoyed it on the morning with a cup of coffee.. thank you.
Thanks so much Connie!
Can I use a homemade crust or does it have to be frozen?
No, feel free to use your homemade!
OMG— I made this last night from fresh peaches and fresh blueberries. Used a frozen crust. It might be the best pie I have ever made. The topping was fantastic! Thank you for sharing!
Hi! I am from India. The pie looks just amazing and would love to give it a try. Could you please suggest something instead of peaches that I could use with canned blueberries. Thank you
Hi Kavya! It depends on what you can get…apricots or apples might be nice, or I wonder if mango would even work.
This recipe sounds amazing. Curious if you have any insight on how it would turn out using frozen peaches and blueberries?
Frozen fruit is so good these days I think it would be fine.
Delicious !!! First time to make this pie. Thank you for sharing.
Thanks Jo, I’m glad you liked it 🙂
This is the second time I’ve made this pie this summer. – it has turned out awesome both times!! One of the easiest pies to put together and bake. I really enjoy your blog – you have such good recipes with wholesome ingredients. I like that you use fresh fruits and vegetables often. I live in Washington state and we have a garden every summer. We are surrounded by orchards. I look forward to reading your posts! Enjoy your day!
Thanks SO much Nancy ~ I can just imagine the good food coming out of your kitchen this summer!
