This Berry Pie blends sweet and tart notes from four berries into an easy single-layer pie. With a pre-baked crust and a stovetop filling made from strawberries, blueberries, raspberries, and blackberries, it’s a perfect spring and summer dessert that requires minimal oven time.

Berry Pie
I’ve always had a soft spot for pie, and this Mixed Berry Pie is one I could happily finish on my own. Fresh-picked berries still warm from the sun are unbeatable, and turning them into a bright, flavorful pie is one of my favorite ways to enjoy summer.
Berry picking is a cherished tradition in many places. I usually freeze some early-season berries so I can combine strawberries, raspberries, blueberries, and blackberries later to make this pie every year.

Instead of a double-crust pie, this recipe uses a single pre-baked crust and a stovetop filling that sets in the pan. The result is a pie that’s delicious served warm, at room temperature, or chilled — and it keeps oven time to a minimum, which is ideal for hot-weather baking.

How To Make Mixed Berry Pie From Scratch:
1. Prepare and prebake a single-crust pie shell according to the package instructions or your favorite recipe.
2. In a large saucepan, whisk together the granulated sugar and cornstarch until smooth.
3. Stir in the butter, berries, lemon juice, and cinnamon. Cook over medium heat, stirring occasionally, until the mixture comes to a boil and the fruit has softened.

4. Remove the filling from the heat and pour it into the prebaked crust, spreading gently to level.

5. Cool the pie completely on a wire rack. Allow 6 to 8 hours for the filling to set firmly before slicing.

6. Once set, slice and serve. The pie is lovely chilled, at room temperature, or gently warmed. Top with vanilla ice cream or whipped cream and garnish with mint if you like.

Serve with ice cream or whipped cream and fresh berries for extra color and flavor.

How Long Will Mixed Berry Pie Last?
Room Temperature: Berry pies can keep 2 to 3 days at room temperature in a dry area. In humid climates, refrigerate after the pie reaches room temperature. Store covered with foil or plastic wrap.
Refrigerator: A baked berry pie will stay fresh 4 to 5 days in the refrigerator when loosely covered.
Freezer: Yes — you can freeze the fully assembled pie. Wrap tightly in foil or freezer wrap, or place in a heavy-duty freezer bag. Best within 6 months. Thaw in the refrigerator or at room temperature.

Notes
- Use any single bottom pie crust you prefer — homemade, refrigerated, or frozen. Do not add a top crust, as the pie is not returned to the oven.
- Swap or adjust the berry amounts as long as the total volume is about 5 1/2 cups.
- Cinnamon is optional; omit for a purer berry flavor.
- Omit butter to keep the filling dairy-free, though a tablespoon of butter enhances the flavor.
- You can gently warm slices for serving, but allow the whole pie to cool and set before slicing so the pieces hold together.
