Blackberries. raspberries, strawberries, and blueberries-oh my! Berry Pie is made with alllll the berries and has the most flaky, buttery crust. 

Berry pie is a delicious combination of sweet and tart. The flavors of all four berries create a delicious pie filling that can’t be beat. Add a homemade crust to the mix and you are in business.

Homemade Mixed Berry Pie

Mixed Berry Pie can be made with fresh or frozen berries. I have made the pie using both varieties and they each turn out amazing. Using frozen berries can really save you on some prep time though.

This pie can be served for any holiday or any season. It is very versatile and will be a crowd please no matter what time of year you decide to make it. My favorite way to serve berry pie is with a scoop of your favorite vanilla ice cream. Just hits the spot!

I always prefer making a homemade pie crust but if you need to speed things along a store-bought crust will make whipping up the pie super quick and easy.

How do you thicken a berry pie?

If your berry pie filling is a bit runny you can use cornstarch or flour to thicken it up. A general rule of thumb is 1 teaspoon of cornstarch per cup of fruit. 

Do you need to thaw frozen berries before baking?

Most people think that frozen fruit is more juicy than fresh fruit and that is not true. They both contain the same water content. You don’t need to thaw frozen berries completely in order to begin your pie filling. I just do a partial thaw and get to work. If you are used frozen fruit you might need to increase your cook time by 5-10 minutes.

What is the best way to store a berry pie?

The best way to store a berry pie is at room temperature. I like to store my pie uncovered because extra moisture from plastic wrap will cause the crust to get soggy. 

How do you know when a pie is done baking?

You will know when your berry pie is done baking because the crust will be golden brown and the filling will start to bubble.

  • Place berries, lemon juice and sugar in 3 qt saucepan over medium high heat stirring occasionally.
  • Once the berries start to simmer, turn the heat down to medium and continue cooking for 5 minutes, or until the berries are very soft.
  • Pour about ½ cup of the juice into a bowl.
  • Mix the cornstarch into the juice
  • Return cornstarch juice mixture to the pot and gently mix.
  • Cook for 2 more minutes or until it starts to look thick.
  • Remove from heat and add the butter, stir to combine.
  • With a slotted spoon, ladle berries into an 8 inch pie shell that has been placed in a pie plate.
  • Top pie with pie crust with hole cut into the top for venting or use lattice method (here’s a step by step guide on how to lattice a pie crust).
  • Brush the top of the pie crust with the beaten egg and sprinkle with additional sugar.
  • Bake at 400 degrees F. for 45 to 50 minutes. If the edges of the pie start to brown too quickly you can cover the edges with a 2 inch strip of foil around the edge of the pie.
  • Remove the pie from the oven and cool completely before serving.


  • When you use a slotted spoon to ladle the berries into the pie crust, you’ll have some berry juices leftover. It makes excellent “syrup” for pancakes, waffles, or French toast.
  • You can use fresh or frozen berries for this recipe, both work great. If working with frozen berries just heat them up on the stove long enough to warm them up all of the way, it’ll take a few extra minutes compared to fresh berries.

    I substituted cornstarch with 6 tablespoons of Tapioca. I used Scandinavian pearled sugar to replace course sugar on top.
