I stumbled upon my Mixed Berry Pie by pure chance during winter when fresh berries weren't available anywhere. Turns out frozen fruit creates the most amazing filling without any prep cooking. It's now my favorite pie to whip up any time of year. When you mix sweet raspberries with tangy blackberries and plump blueberries, you get this wonderful blend of tastes all wrapped up in a rich, buttery shell.
Delightful Treats for Any Time
What makes this pie so great is how easy it is. I'm always happy knowing I can just grab frozen berries from my freezer and have an impressive dessert ready for baking in just minutes. The natural berry sweetness combined with my family's old pie crust formula always gets everyone at the table smiling. The easiest recipes often turn out to be the ones we treasure most.
What You'll Need for Mixed Berry Pie
- Frozen Berry Mix: I throw in raspberries, blackberries, and blueberries right from the freezer bag, no need to thaw them first.
- Pie Crust: I use my grandma's old recipe, but ready-made works too—just try making the criss-cross top pattern if you can.
- Sugar: Add just enough to bring out the berries' own sweetness.
- Flour or Cornstarch: This key addition helps you cut perfect slices every time.
- Lemon Juice: A tiny bit makes all the fruit flavors stand out more.
- Butter: A few small chunks create an extra rich filling.

How to Create Mixed Berry Pie
- Roll Out Your Dough
- Work your crust with care—it's what makes your dessert special! Keep some dough aside for making those lovely strips across the top.
- Add Your Berries
- Dump those frozen treasures straight in, mix with sugar, flour, and a splash of fresh lemon. Add tiny butter pieces throughout for extra goodness.
- Weave Your Top Crust
- Don't rush while crossing those strips over each other. I always enjoy watching the design come together.
- Bake Until Done
- Cook until you see a golden top and bubbling filling. Your house will smell amazing while it bakes.
- Cool Down Time
- Let it sit a while, though I won't mind if you can't wait and grab a warm piece with some vanilla ice cream on top.
Sweet Moments Around the Table
This pie has become what everyone asks me to bring to family events. That beautiful purple filling showing through the golden top always gets everyone excited. I love that it works for anything—fancy enough for Christmas dinner but just right for casual backyard get-togethers too. Whenever I bake it, I'm reminded that truly great recipes don't just feed people—they bring them closer together.
Recipe Questions & Answers
- → Why pick frozen fruit over fresh?
Frozen fruit is super convenient, available all year, and often a budget-friendly option. It stays flavorful since it's frozen when perfectly ripe, and it holds up great while baking.
- → How do I avoid a runny filling?
Be precise when measuring your fruit, add the right amount of cornstarch, and let the filling bubble in the middle before taking it out. Cool it fully to set the filling.
- → Can I prepare this in advance?
Yes! Make it a day early and keep it at room temperature. For longer storage, refrigerate for up to 5 days. Warm it slightly before serving, if you'd like.
- → What's the egg wash for the crust?
An egg wash makes the crust turn a lovely golden brown with a shiny finish. It also holds the edges of the top and bottom crust together like a seal.
- → How can I tell it's fully baked?
Your pie is ready when the crust is golden and the center of the filling is bubbling (not just the edges). This usually takes around 75 minutes.
