Strawberry Blueberry Pie with Frozen Berries
This strawberry blueberry pie with crumb topping is incredible! The berry filling is SO GOOD I could eat it with a spoon! It's bursting with berry flavor that's boosted with lemon juice, vanilla, and a little cinnamon. Truly a delicious summer dessert! But the best part? You DON'T need fresh berries for this recipe.
I love baking with frozen berries because it's so much easier to make your strawberry blueberry pie pie filling. No slicing or washing, and no worrying about berries going bad before you get a chance to bake your pie!
One Crust Strawberry Blueberry Pie with Crumb Topping
The crumb topping on this old fashioned strawberry blueberry pie is TO DIE FOR. It's based on my Cherry Crumb Pie, my Apple Pie With Graham Cracker Crust, and my Cherry Coffee Cake, and it's my favorite part of this pie!
It's perfectly buttery and so easy to make! Plus, it makes this a one crust strawberry blueberry pie, which is so much easier than a pie with a top crust!

How do you make fruit pie not runny?
I always pre-cook my fruit pie filling. Allowing your strawberry blueberry pie pie filling to thicken lets the liquid evaporate and makes it much less likely to end up runny.
Another important step is to let your fruit pies cool completely! If you cut into your pie too early, even if you pre-cooked your filling, it'll be too runny. I recommend letting it cool for several hours or until the bottom is no longer warm.
Ingredients
This one crust strawberry blueberry pie is made with simple ingredients, many of which you'll have on hand already! Check the recipe card below for full ingredient measurements, but here's a quick look at what you'll need:
- pie crust - I recommend making your own pie crust, and my go-to is always my Flaky Butter Pie Crust -- it's a homemade pie crust that is perfect for the fruit filling on this pie! But you can definitely use any one-crust flaky pie crust recipe you like, or you can use a store-bought pie crust!
- strawberries and blueberries - I typically make this strawberry blueberry pie with frozen berries, but if you have fresh berries that's even better! They should be washed and hulled, and the strawberries cut in half (or quarters if they're really large berries). If you do use fresh strawberries and blueberries, you'll want to add ¼ cup of water to your filling mixture to help it all mix together.
- sugar - I use granulated sugar in this filling to add the perfect amount of sweetness!
- fresh lemon juice - brings out the tartness in the berries and helps to balance out the flavors.
- cornstarch - to thicken our strawberry blueberry pie filling, we're adding cornstarch and cooking it down.
- vanilla - for the best flavor, I like to use pure vanilla extract. Or you can make your own!
- cinnamon - I love the flavor that a little ground cinnamon adds to this berry filling! You can omit it, of course, but I think you'll like it! And if you like that warm spice flavor, try my Pumpkin Pie in Graham Cracker Crust!
- butter - we'll add a little salted butter to give our filling some richness. If you prefer to use unsalted butter, add a pinch of salt to your filling.
Then, we're adding a buttery brown sugar crumb topping on top of the filling! Here's you'll need for that:
- all-purpose flour - creates the base for the crumb topping in your strawberry blueberry pie.
- light brown sugar - Adds a rich, caramel flavor to the crumb topping for this mixed berry pie.
- granulated sugar - white sugar brings sweetness and crispiness to the topping.
- salted butter: Ensures a buttery, flaky texture that complements the juicy fruit filling perfectly. Your butter should be cubed and chilled. If you prefer to use unsalted butter, just add a couple pinches of salt in with your crumb mixture.
See recipe card for ingredient quantities.
Equipment
For this strawberry blueberry pie with crumb topping, you'll need a 9-inch pie dish, of course! I like to use this Pyrex pie plate, because I like being able to see through the bottom to make sure the crust isn't soggy! You'll also need a pastry blender (or fork) to mix up your crumb topping. And you'll also want a rolling pin to roll out your pie crust -- I like this marble tapered rolling pin!
You'll also want a saucepan to mix up your blueberry strawberry pie filling, and I like to use a kitchen scale for measuring flour.
Instructions
The recipe card below will give you detailed step-by-step instructions for making this pie, as well as full ingredient measurements and a recipe video! But here's a quick look at how you'll make this strawberry blueberry pie recipe!
In a large bowl, use a pastry cutter or fork to mix cold butter into the rest of your crumb topping ingredients. Let chill in fridge.
Cook berries, cornstarch, lemon juice, sugar, cinnamon, and butter until thickened. Stir in vanilla.
Roll out chilled pie dough and press into a lightly floured pie dish. Crimp sides and blind bake.
Dust prebaked pie crust with "crust dust" (see below), then add filling.
Sprinkle your crumb topping on top of the pie, and bake until it's a deep golden brown!
Be sure to let your old fashioned strawberry blueberry pie cool completely at room temperature before serving. And a scoop of vanilla ice cream is highly recommended!
Hint: To make sure your pie doesn't stick to the pie pan, dust a little flour into the pie plate just before adding your pie dough.
Berry Pie Filling Without Cornstarch
If you love the idea of this pie but don't have cornstarch (or you prefer not to use it), you can definitely substitute arrowroot powder instead. Because arrowroot is a more powerful thickener than cornstarch, you'll only need to use 2 tablespoons of arrowroot in your filling.
Storage
You can store this one crust strawberry blueberry pie at room temperature under a cake dome for up to a day, or in the fridge covered tightly with plastic wrap or an airtight container for up to 3 days. Let it come to room temperature before serving.
You can also freeze this pie, well wrapped, for up to two months. If you do freeze it, I'd recommend not using a glass pie plate.
Frequently Asked Questions
I love to add a little butter to the pie filling to make it a little richer, and add that lovely buttery flavor.
That's often a matter of preference -- I like to cook down most of my fruit filings (like this strawberry blueberry pie filling) to avoid too much liquid in the pie after baking. This is especially important if you're using frozen fruit.
If you want to maintain the firm texture of your fresh fruit, one compromise you can try is to cook down your filling using only half of your fruit. Then, once it's slightly thickened, you can remove it from the heat and add in the rest of your fresh fruit and that's your pie filling! It's the best of both worlds!
Make "crust dust" to prevent a soggy bottom of the pie! This is a trick I learned from King Arthur Baking: Just combine equal parts all-purpose flour and granulated sugar (I use 2 teaspoons of each) and sprinkle evenly all over the inside of your pie crust just before adding your filling! It creates a barrier between the crust and the filling to keep the crust dry, firm, and flaky!
I definitely recommend it! I list the steps in the recipe card below to prebake, or "blind bake" your crust to make sure that it comes out firm and flaky!
It could be that your pie filling was not sufficiently thickened before adding, or that you didn't use enough cornstarch in your filling.
I prefer cornstarch, but you can also use tapioca starch or arrowroot powder.
There are a few reasons this might happen: your filling might not have thickened up enough to and it's too runny, which can make it soak into the bottom crust. Or your bottom crust didn't bake all the way through. The best ways to avoid both of these issues is to pre-bake your bottom crust, be sure to cook your filling until it's thickened, and add a layer of "crust dust" to act as a barrier between the filling and the crust as your pie bakes!
Top Tip
Make "crust dust" to prevent a soggy bottom crust! Combine equal parts all-purpose flour and granulated sugar (I use 2 teaspoons of each) and sprinkle evenly all over the inside of your pie crust just before adding your filling! It acts as a barrier for fruit juices and moisture and keeps the crust dry, firm, and flaky!
