Why You’ll Love This Mixed Berry Streusel Pie

I LOVE summer because it means it’s berry season! The mix of berries (yes, even if you use frozen berries) creates a vibrant filling that is both tart and sweet while covering the top with streusel adds a delightful crunch to each bite. Similar to a French Fruit Galette, this is perfect for any gathering and will surely become a staple in your dessert repertoire for hot summer days, or any day really! Whether you’re hosting a dinner party or simply satisfying a sweet tooth, this pie is bound to be a hit!

Ingredients Needed For Mixed Berry Streusel Pie

This pie is so easy and uses some of my favorite fruits- BERRIES! Made with a few simple ingredients and pantry staples!

• 9-inch flaky pie crust: You can use store-bought for convenience or make your own for that homemade touch.
• Frozen mixed berries: A vibrant combination of blueberries, raspberries, and blackberries.
• Vanilla extract: Adds a depth of flavor to the berry filling.
• Granulated sugar: Sweetens the berries perfectly.
• All-purpose flour: Helps thicken the berry mixture.
• Streusel topping: A delicious blend of flour, granulated sugar, brown sugar, rolled oats, softened butter, and a pinch of salt.

Variations

• Fresh berries: Use fresh to create a combination of berries for a more intense flavor.
• Lemon zest: Add a teaspoon of lemon zest to the filling for a zesty twist.
• Maple syrup: Drizzle some maple syrup over the top for added sweetness.
• Gluten-free: Substitute with a gluten-free flour blend for the pie crust and streusel.
• Almond flour: Use almond flour in the streusel for a nutty flavor.
• Grain-free pastry crusts: try a grain-free pastry crust or a traditional butter pie crust for different textures.

How To Make a Mixed Berry Streusel Pie

For full recipe details, including ingredient measurements, see the printable recipe card at the bottom of this post. Here are my step by step instructions for making this pie:

1. Preheat Oven

Preheat your oven to 350° F.

2. Prepare the Crust

If using frozen pie crust, remove it from the freezer and let it thaw. If using homemade pie crust, keep it refrigerated until ready to fill. 

Pro Tip: I love to use my recipe when I want an easy homemade crust.

3. Make the Filling + Assemble the Pie

In a large bowl, stir frozen berries, vanilla extract, 1/2 cup sugar, and flour until well coated.

Pro Tip: Add a splash of lemon juice to brighten up the berry filling.

Pour the berry mixture into pie crust using a slotted spoon and even out the top.

4. Prepare the Streusel

In separate medium bowl, measure out streusel ingredients. Using your hands, mix the streusel until it comes together and the butter is well incorporated throughout and everything is like moist sand.

This recipe for streusel makes a crazy amount, especially for a pie, but that’s how I like it. I used all but about 1/2 cup. Feel free to halve the topping recipe for a more socially acceptable amount of streusel for your pie.

5. Top the Pie With Streusel + Bake

Spread 3/4 of the streusel over the frozen berries. Bake pie for 1 hour or until crust and topping are golden brown.

Pro Tip: Place your pie on a baking sheet to catch any spills. You’ll thank yourself later- I promise. 😉

6. Remove From Oven + Let Rest, Garnish and Serve!

Now, I know it’s going to be hard, but let your mixed berry pie cool completely before cutting into it. If you wait, I assure you it will cut so obnoxiously well that you’ll never want to make another kind of pie again. IF you cut into this when it’s still warm?! I make no such promises. But in both situations, it will taste REALLY good.

Garnish with whipped cream or vanilla ice cream, serve and enjoy!

Storage + Make Ahead Directions

Store any leftovers at room temperature for up to two days or in the fridge for up to a week.

Freezing Directions: Wrap the pie in plastic wrap and foil before freezing. It should last for up to three months.

Make Ahead Directions: Prepare the pie up to a day before and keep it at room temperature until ready to serve.
