Perfect Berry Pie with Crumb Topping

I love a fabulous fruit pie, and this berry pie recipe is one I make all year round. It’s so simple, bursting with fruit, and has the best crumble topping.

I love this mixed berry crumb pie because you can use frozen berries to make it. No waiting around for them to be in season! I definitely make it more in the summer because this mixed berry pie with crumb topping just screams summer to me, but with frozen fruit, there’s no reason you can’t make it in the dead of winter, too.

I use my favorite all-butter crust for this pie. It’s the perfect buttery, flaky base for all that fruit. The filling has a perfect consistency – I hate a runny pie, and this one does not have that problem!

Topping off this blueberry raspberry pie with crumb topping is a simple brown sugar crumble topping. It adds a nice sweet, crunchy texture that pulls the whole pie together.

What You Need to Make Mixed Berry Pie

  • Brown Sugar: This is used in the crumble. Be sure to measure your brown sugar correctly.
  • All-purpose flour: For the crumble topping – be sure to measure it correctly.
  • Cold unsalted butter: It’s important to start crumble topping with cold butter.
  • Granulated sugar: To coat the berries
  • Cornstarch: I find this thickens better than regular flour.
  • Ground cinnamon: All my berry pies use a pinch!
  • Frozen mixed berries: Use your favorite – I love a triple berry blend. Make sure they’re thawed and drained if using frozen berries.
  • Lemon juice: Cuts the sweetness if your berries are in season or extra sweet.
  • Pie Crust: I love my all butter pie crust recipe but you can also use a semi-homemade version.

Mixed Berry Pie with Frozen Berries vs Fresh Berries

I like to use frozen berries for this recipe because they’re available year-round and taste great in the pie. Berries that are out of season are usually not as sweet when you buy them fresh.

If they are in season and you want to use fresh berries, you can do that without making any adjustments. You can use the same amount as frozen.

If you’re making a frozen berry pie, it’s very important to thaw them completely and then drain them thoroughly. Frozen fruit has more liquid – if you don’t drain it off, your filling will be thinner and runnier.

How to Make Berry Pie

  1. Pie crust: Prepare the pie crust and fit it into a 9” pie pan. Chill it for 30 minutes while you prepare the topping and filling.
  2. Topping: Whisk the brown sugar and flour in a mixing bowl. Grate the cold butter into the bowl, and then use a pastry cutter to cut the butter into the dry ingredients. Once the mixture resembles coarse crumbs, set the bowl aside.
  3. Pie Filling: Whisk the granulated sugar, cornstarch, and cinnamon in a small bowl. Place the mixed berry pie filling in a large bowl and sprinkle the cornstarch mixture over the top. Gently toss to combine.
  4. Assemble: Transfer the berry filling to the chilled pie crust. Sprinkle the brown sugar topping over the top.
  5. Bake Pie: Place the pie plate on a sheet pan (to catch any drips) and bake the berry crumble pie for 10 minutes at 425°F, then lower the temperature to 350°F and finish baking the pie until the crust is golden and the filling is bubbling.

Recipe Swap

  • Lattice: Instead of a crumb topping, use a second pie crust to create a lattice top for your pie with strips of a second pie dough.
  • Double crust: Or cover the whole pie with a second crust. Just remember to cut slits so the steam can vent while the pie bakes.

Expert Tip

  • Whether you use the crumb topping or use a double crust, be sure to bake the pie at the higher temperature first and then lower the oven temperature. The high temperature ensures the bottom crust is cooked properly.
  • Once you’ve baked the pie, allow it to cool to room temperature before storing.
  • Refrigerator: Loosely cover it with plastic wrap and store it in the fridge for 2-3 days.
  • How to freeze berry pie: You can freeze the baked pie, too. Once it’s cool, wrap it tightly with plastic wrap. It will keep in the freezer for up to three months.
  • The pie is delicious plain, but adding a scoop of vanilla ice cream or a spoonful of whipped cream is a nice finishing touch.


How do you keep a berry pie from being runny?

To keep a berry pie from being runny, you need to use cornstarch in the filling. Cornstarch is a thickening agent, and it thickens the juices from the fruit. It’s also important to let the pie cool before slicing it. The filling will thicken as it cools – if you slice it too soon, the warm filling will ooze out.

Can you use frozen fruit to make pie?

Frozen fruit works great in pie, just be sure to thaw and drain it well before making the filling. You don’t want extra liquid in your pie.

How do you thicken berry pie filling?

I prefer using cornstarch, but you can also use all-purpose flour.

  1. Super easy, and turned out fabulous. I had a humongous bag of frozen berries: strawberry. raspberry, blueberry and blackberry to use up today. It turned out wonderful. Thanks so much for sharing your recipe.
