I bake blueberry peach pie when summer fruit is good enough that I do not want to do much to it. Peaches bring the soft honeyed filling, blueberries bring the deep color, and a little cinnamon and allspice make the whole pie smell like it belongs on the windowsill.
This is a two-crust pie, and I usually make a lattice because the bubbling purple filling peeking through always looks worth the extra few minutes. When I am tired, I lay the second crust on top, cut vents, and call it done.
The hardest part is waiting. Four full hours of cooling sounds dramatic until I cut a hot fruit pie once and watch the filling run everywhere. Now I let it set, then slice it cleanly and add ice cream if the day calls for it.
Why I keep coming back to this
- Blueberries and peaches balance each other: one jammy, one soft and fragrant.
- The filling uses flour to thicken, so there is no separate stovetop step.
- A lattice top lets steam escape and shows off the fruit.
- The oven starts hot at 400°F, then drops to 375°F for a steady bake.
- Four hours of cooling gives the filling time to thicken.
- Leftovers keep well in the refrigerator for up to 5 days.
What you need (and what each one is doing)
- 1 recipe homemade pie crust (full recipe makes 2 crusts: 1 bottom and 1 top).This earns its place by balancing texture, flavor, or moisture.
- 3/4 cup + 1 Tablespoon granulated sugar (divided).Sugar sweetens and helps the edges brown. I do not add more than the recipe calls for because blueberries already bring plenty.
- 6 Tablespoons all-purpose flour (spooned & leveled).Flour gives structure. I spoon it into the measuring cup and level it off because a packed cup makes baked goods heavy.
- 3/4 teaspoon ground cinnamon (divided).
- 1/8 teaspoon ground allspice.
- 3 cups sliced, peeled fresh peaches (about 5).Ripe peaches bring soft syrupy pockets. I slice them a little thicker than seems necessary because thin slices disappear into the filling.
- 1 1/2 cups blueberries (210g).I fold berries gently so a few burst and a few stay whole. Fresh berries look neatest, but frozen berries have saved this recipe for me plenty of times.
- 1 Tablespoon unsalted butter (14g).Butter is there for flavor and tenderness. When it needs to be cold, I cube it small; when melted, I let it cool a bit first.
- 1 large egg, beaten.Eggs help everything set instead of falling apart. I beat them well first so no streaks of egg white show up later.
How I make it
Step 1 — Chill the crust
I prepare a double pie crust through the chilling step before I touch the fruit. Cold dough is easier to roll, and fruit filling waits better than warm pastry does.
Step 2 — Mix the filling
In a large bowl, I whisk 3/4 cup granulated sugar with the flour, 1/2 teaspoon cinnamon, and allspice. Then I fold in the sliced peaches and blueberries until the fruit is evenly coated. The flour may look dry at first, but the fruit juices hydrate it as it sits.
Step 3 — Fill the bottom crust
I heat the oven to 400°F (204°C). On a floured surface, I roll one chilled dough disk into a 12-inch circle and fit it into a 9-inch pie dish. I spoon in the fruit filling, then cut the Tablespoon of butter into tiny pieces and scatter them over the top.
Step 4 — Add the top crust
I roll the second dough disk into another 12-inch circle. For a lattice, I cut 1-inch strips and weave them over the filling, sealing the strips to the bottom crust. If I am making a full top crust, I cut vents so steam can escape. Either way, I trim and crimp the edges.
Step 5 — Bake and cool completely
I brush the top with beaten egg, then mix the remaining 1 Tablespoon sugar with the remaining 1/4 teaspoon cinnamon and sprinkle it over the crust. The pie bakes on a sheet pan for 20 minutes at 400°F (204°C), then 30 to 35 minutes at 375°F (190°C). I cool it for 4 full hours before slicing.
Tips from my kitchen
- Use a sheet pan.Fruit pies bubble, and I would rather wash a pan than scrub the oven floor.
- Shield the edges.After the first 20 minutes, I add a pie shield if the crust is browning quickly.
- Cut peaches evenly.Similar slices soften at the same pace.
- Honor the cooling time.Four hours is what turns hot fruit juice into sliceable filling.
Variations I have actually tried
- All-blueberry:replace peaches with more blueberries and keep the same thickener.
- Nectarine pie:use sliced nectarines instead of peeled peaches.
- Crumb top:use one bottom crust and finish with a brown sugar crumble.
- Lemon lift:add 1 teaspoon lemon zest to the filling.
- Rustic top:skip the lattice and use a vented full crust when I want speed.
Storing and making ahead
I cover leftover pie tightly and refrigerate it for up to 5 days. Slices can be eaten cold, but I like warming them at 325°F (163°C) for 10 minutes to wake up the crust. I do not cover the pie until it is fully cool, because trapped steam softens the top crust.
My pie timing notes
I plan this pie backward from serving time. If I want dessert at 7, the pie needs to be out of the oven by 3 so the filling has a full 4 hours to settle. That cooling window is not wasted time; it is when the flour-thickened juices turn from bubbling syrup into a filling that stays mostly inside each slice.
I also watch the crust color more than the exact minute on the timer. A pale fruit pie usually means the bottom crust has not had enough time, while a deeply golden top with bubbling fruit tells me the filling reached the heat it needed.
Frequently asked questions
Do I have to peel the peaches?
I usually peel them for a smoother filling, but thin-skinned ripe peaches can be left unpeeled if the texture does not bother you.
Can I use frozen blueberries?
Yes. I add them frozen and expect a little more juice. I keep the flour amount the same and make sure the pie bubbles before pulling it.
Why does the pie need 4 hours to cool?
The filling thickens as it cools. If I slice too soon, the fruit juices run out even if the flavor is wonderful.
Can I make the pie crust ahead?
Yes. I keep pie dough in the refrigerator for a couple of days or freeze it well wrapped. Thaw frozen dough in the refrigerator before rolling.
How do I know the pie is done?
The crust should be deeply golden and the filling should bubble in the center, not just around the edges.
A patient cooling rack is the real secret to a clean slice of blueberry peach pie.
