Buttery flaky crust brimming with sweet-tart juicy blueberries, served warm with melting vanilla ice cream for a nostalgic, crowd-pleasing summer dessert.

Ingredients

Fresh blueberries 680 grams (6 cups)
Vanilla ice cream 480 ml (2 cups / 1 pint)
All-purpose flour 315 grams (2.5 cups)
Cold unsalted butter 226 grams (1 cup / 2 sticks)
Granulated sugar 100 grams (1/2 cup)
Cornstarch 24 grams (3 tablespoons)
Fine sea salt 5 grams (1 teaspoon)
Fresh lemon juice 30 ml (2 tablespoons)
Lemon zest 2 grams (1 teaspoon)
Ground cinnamon 0.5 grams (1/4 teaspoon)
Ice water 60-80 ml (1/4 - 1/3 cup)
Large egg (for egg wash) 50 grams (1 large egg)
Coarse sanding sugar 12 grams (1 tablespoon)

Steps

1

Prepare flaky pie crust

In a large mixing bowl, combine 315g all-purpose flour and 5g (1 tsp) fine sea salt. Add 226g cold cubed unsalted butter, and use your fingertips to rub the butter into the flour until the mixture forms coarse, pea-sized crumbs. Drizzle in 60-80ml ice water, 1 tablespoon at a time, mixing gently until the shaggy dough just comes together (do not overwork, as this creates tough crust). Split the dough into two equal 2.5cm-thick discs, wrap tightly in plastic wrap, and chill in the refrigerator for 30 minutes before rolling.

Mix blueberry filling

In a large ceramic mixing bowl, toss 680g fresh blueberries with 100g granulated sugar, 24g (3 tbsp) cornstarch, 30ml (2 tbsp) fresh lemon juice, 2g (1 tsp) lemon zest, and 0.5g (1/4 tsp) ground cinnamon until every berry is evenly coated. Let the mixture rest for 10 minutes at room temperature to allow berries to release their natural juices, stirring once at the 5-minute mark.

Assemble the uncooked pie

Preheat your oven to 200°C (400°F). Roll one chilled dough disc out on a lightly floured surface to a 30cm (12-inch) circle, 0.3cm (1/8-inch) thick. Gently lay the rolled dough into a 23cm (9-inch) metal pie dish, pressing it firmly against the bottom and sides, leaving a 2.5cm (1-inch) overhang around the rim. Pour the rested blueberry filling and all its accumulated juices into the crust-lined dish. Roll the second dough disc into a matching 30cm circle, drape it over the filling, trim excess dough to a uniform 2.5cm overhang, crimp the top and bottom crust edges tightly to seal, and cut four 5cm (2-inch) slits in the top crust to vent steam.

Bake to golden perfection

Beat 1 large egg with 15ml (1 tbsp) water to make a smooth egg wash, then brush it evenly over the entire top crust and crimped edge of the pie. Sprinkle 12g (1 tbsp) coarse sanding sugar over the washed crust for a crunchy, sparkling top. Place the pie on the middle oven rack, with a rimmed baking sheet on the rack below to catch any bubbling berry drips, and bake at 200°C (400°F) for 25 minutes. Reduce the oven temperature to 190°C (375°F), and bake for an additional 30 minutes, until the crust is deep golden brown and thick purple filling is visibly bubbling through the top slits.

5

Let pie set properly

Transfer the hot baked pie to a metal wire cooling rack, and let it rest for a full 45 minutes at room temperature before slicing. This resting period allows the cornstarch-thickened berry filling to set firmly, preventing runny, oozing slices when cut. Resist the urge to slice early, as hot filling will not hold its shape.

6

Serve with vanilla ice cream

Cut the slightly warm, set pie into 8 equal wedges. Place one wedge on each dessert plate, and top each slice with one 60ml (1/4 cup) standard scoop of premium vanilla ice cream, set slightly off-center on the pie wedge so it melts slowly over the crust and filling. Serve immediately, before the ice cream melts completely into the pie.

Tips

1.Keep all pie crust ingredients (butter, water, even flour) as cold as possible before mixing — cold butter creates steam as it bakes, which forms the signature flaky, layered crust texture instead of a tough, dense crust.
2.If using frozen blueberries instead of fresh, do not thaw them before mixing into the filling; add an extra 8g (1 tbsp) of cornstarch to absorb excess juice released as the berries bake, to avoid a runny filling.
3.If the crimped pie edges start to darken too quickly during baking, wrap a narrow strip of aluminum foil around the pie rim for the final 15 minutes of cook time to prevent the thin edges from burning.

Blueberry Pie à la Mode:Frequently Asked Questions

1.Can I use frozen blueberries instead of fresh for this pie?
You absolutely can—no need to thaw them first, just toss frozen berries with an extra 1 tablespoon of all-purpose flour to absorb excess released moisture as they bake, so your filling doesn’t turn runny. Skip pre-rinsing frozen berries to avoid extra water, and add 2 minutes to bake time if needed to ensure the filling bubbles fully through the center.
2.How do I keep my bottom pie crust from getting soggy from the juicy blueberry filling?
Start by blind baking your bottom crust for 10 minutes at 400°F with pie weights or dried beans before adding the filling. For extra protection, brush the warm pre-baked crust with a thin layer of beaten egg white to create a moisture barrier, so berry juices don’t seep in and turn the buttery crust soft instead of flaky.
3.Do I have to serve the pie warm for the à la mode component, or can I use cold leftover pie?
Warm pie is ideal for that classic nostalgic experience, because it makes the vanilla ice cream melt into creamy, sweet pools that mix perfectly with the tart blueberry filling. If using cold leftover pie, pop individual slices in the microwave for 10 to 15 seconds just to take the chill off before adding your ice cream scoop.
4.What’s the trick to getting the flakiest possible crust with cold unsalted butter?
Cut your cold unsalted butter into ½-inch cubes, then pop them back in the fridge for 10 minutes before mixing into your all-purpose flour. You want the butter to stay completely solid as you work it into the flour, aiming for pea-sized crumbs—those solid bits melt in the oven to create distinct, buttery flaky layers.
5.How do I adjust the granulated sugar amount if my blueberries are extra sweet or extra tart?
Always taste your blueberries first before mixing the filling! If they’re very ripe and sweet, cut the granulated sugar by 2 tablespoons to let the bright, natural berry flavor shine. If they’re underripe or extra tart, add 1 to 2 extra tablespoons of sugar, plus a tiny squeeze of lemon juice to balance the flavor.
6.Can I make this blueberry pie ahead of time for a summer cookout or party?
You can bake the pie fully 1 day ahead, let it cool completely, and store it loosely covered at room temperature. Wait until right before serving to warm individual slices and scoop vanilla ice cream—never add ice cream ahead, as it will melt and make the crust soggy, and skip fridge storage, which makes flaky crust turn stale quickly.
7.Why is my blueberry pie filling runny even after I pulled it out of the oven?
Runny filling usually stems from one of three common issues: not using enough flour to thicken berry juices, not letting the pie cool for at least 3 hours post-bake (the filling sets as it cools!), or using wet thawed blueberries without extra thickener. If it stays runny, serve it in shallow bowls with extra ice cream to catch the tasty juices.
8.Can I make this recipe if I don’t have time to mix up a homemade pie crust from scratch?
Absolutely! Grab a good-quality store-bought refrigerated double pie crust—look for one made with real butter for the closest flaky texture to homemade—to cut down on prep time. Keep the crust cold until you’re ready to line your pie dish, and follow the same blind baking tip for the bottom crust to avoid sogginess.
9.What simple upgrades can I add to the vanilla ice cream to make this à la mode serving feel extra special?
For a fun, easy upgrade, roll scoops of vanilla ice cream in crushed graham cracker crumbs or toasted sliced almonds before setting them on the warm pie. You can also drizzle a little warm salted caramel over the top, or add a light sprinkle of fresh lemon zest to cut richness and complement the sweet-tart blueberry flavor.

OMG this blueberry pie à la mode was the star of our Sunday family dinner! I was worried the crust would be tricky since it’s marked medium difficulty, but the instructions were so clear. The blueberry filling wasn’t too sweet, paired with vanilla bean ice cream? *Chef’s kiss* My 7 year old asked for seconds before she even finished her first slice. 10/10 will make again for our next potluck!

Wait, 2 and a half hours cook time? Is that all inactive or is there a lot of hands-on work? I’m a pretty new baker, don’t want to get in over my head here. Looks incredible though, dying to try it for my girlfriend’s birthday next week.

Great question! About 45 minutes of that is hands-on time (making the crust, prepping the filling, crimping edges) – the rest is chill time for the crust and bake time, where you don’t need to hover! If you take it slow with the crust steps, you’ve totally got this for your girlfriend’s birthday, it’s such a thoughtful pick 😊

Game changer alert! I added a tiny bit of lemon zest to the filling like my grandma used to do, and it cut the sweetness perfectly. Served this warm with salted caramel ice cream instead of plain vanilla for our neighborhood block party and people were begging for the recipe. Already sent the link to three of my neighbors!

Oh the lemon zest idea is genius! Did you keep the sugar amount the same as the recipe calls for when you added the zest? I’m worried it’ll be too tart if I skimp but don’t want it cloying either.

3 days ago

Love the lemon zest hack! If you add 1-2 tsp of fresh zest, you don’t need to adjust the sugar amount at all – the bright citrus flavor balances the sweetness without making it tart. The salted caramel ice cream swap sounds insane, I need to try that next time I make it!

SO good. I was skeptical about the cornstarch amount in the filling at first, thought it would be gummy, but it set perfectly after letting it cool like the recipe said. Had a slice with a big scoop of vanilla ice cream after my softball game last night and it hit every single spot. Only note: I’d add a little extra cinnamon next time, personal preference!

Tried this last night for dessert after taco night, and my kids loved it – even my pickiest eater who swears he hates all fruit ate two slices! I did use a store-bought crust because I ran out of time to make homemade (don’t judge me 😂) and it still turned out amazing. Can’t wait to try the homemade crust next time when I have more time to prep.

Girl I use store-bought crust for every pie ever, no judgment here! No one can tell the difference once it’s loaded up with that blueberry filling and ice cream on top, trust me.

Made this in my tiny dorm kitchen last weekend for my roommates, and it was a hit! Only thing is I burned the edge of the crust a little because I forgot to put the foil shield on like the recipe said. Oops. Still tasted fire though, especially with the cheap vanilla ice cream we had in the mini fridge. Worth the 2.5 hours even with my tiny counter space.

1 week ago

So glad it worked out even with the tiny dorm kitchen and slightly crispy edges! Pro tip for next time: you can cut a ring of aluminum foil before you even put the pie in the oven and set it on top once the crust is as golden as you want it, no last-minute scrambling. I’ve definitely burned my share of crust edges too, no shame 😂

I’ve been making blueberry pie for 60 years, and this recipe is up there with my own! The lattice crust instructions were so easy to follow, I taught my 12 year old granddaughter how to do it while we baked yesterday. We served it with homemade vanilla ice cream, and the whole family said it was the best pie they’d had all summer.

Wait the lattice crust is what’s scaring me most! How bad did you mess up the first time you tried it? I feel like mine will look like a lumpy mess.

2 days ago

Don’t stress about the lattice looking perfect! Those steps are written with total beginners in mind, and even if your strips are uneven or a little broken, it tastes just as good – plus, rustic pies feel extra cozy, if you ask me. If lattice feels too intimidating your first go, you can always swap it for a full top crust with a few small vent cuts, no one will complain!

Meal prepped this for a weekend camping trip, and it held up so much better than I thought it would! I stored it in a cooler, sliced it up at the campsite, and served it with those little individual vanilla ice cream cups we packed. Everyone in my hiking group was raving about it, even the guy who swears he ‘doesn’t like fruit desserts’. Total win, will be making this for every group trip from now on!

That’s such a good call bringing pie camping! I never think to make actual dessert for trips, I usually just toss s’mores supplies in the cooler and call it a day. Gotta add this to our menu for our upcoming lake trip!

Has anyone tried making this with a gluten-free flour blend for the crust? I have celiac and would love to make this for my sister’s baby shower next month, but I don’t want to waste a bunch of blueberries if the crust turns out crumbly and gross. Looks so good I’m already craving it!

2 days ago

I made it with Cup4Cup gluten free flour last month and it worked perfectly! I did add an extra tablespoon of cold butter to the crust to keep it from getting too crumbly, and it was indistinguishable from regular crust. Everyone at my book club ate it and didn’t even realize it was GF!

yesterday

Great tip from GF_Baker_Mia! I’ve also tested this recipe with Bob’s Red Mill 1-to-1 gluten free flour with great results, just make sure your butter is extra cold to keep the crust flaky. Hope it turns out perfect for the baby shower!
