intro

Buttery crisp graham cracker crust loaded with bright, juicy sweet-tart blueberry filling: this easy, iconic pie is perfect for warm summer gatherings.

Ingredients

Graham cracker crumbs 180 grams (1.5 cups)
Unsalted butter (melted, for crust) 85 grams (6 tablespoons)
Granulated sugar (for crust) 25 grams (2 tablespoons)
Fresh blueberries (divided) 680 grams (6 cups)
Granulated sugar (for filling) 100 grams (1/2 cup)
Cornstarch 24 grams (3 tablespoons)
Fresh lemon juice 30 ml (2 tablespoons)
Lemon zest 1 teaspoon
Fine sea salt 1/4 teaspoon
Pure vanilla extract 5 ml (1 teaspoon)
Unsalted butter (for filling) 28 grams (2 tablespoons)

Steps

1

Prep and prebake crust

Preheat your oven to 175°C (350°F). In a medium bowl, mix 180g graham cracker crumbs, 25g (2 tbsp) granulated sugar, and 85g melted unsalted butter until all crumbs are evenly moistened with the texture of wet sand. Press the mixture firmly into the bottom and 5cm (2 inches) up the sides of a 23cm (9-inch) glass pie dish. Bake for 10 minutes, then transfer to a wire rack to cool completely for 15 minutes before adding filling.

Step 1
step1：Prep and prebake crust
2

Cook blueberry base

In a medium saucepan over medium heat, combine 4 cups (455g) of the fresh blueberries, 100g (1/2 cup) granulated sugar, 30ml (2 tbsp) lemon juice, 1 tsp lemon zest, and 1/4 tsp fine sea salt. Stir gently and bring to a low simmer, cooking for 5 minutes until blueberries burst and release their deep purple juices, stirring occasionally to prevent sticking to the pan bottom.

Step 2
step2：Cook blueberry base
3

Thicken the filling

In a small bowl, whisk 24g (3 tbsp) cornstarch with 45ml (3 tbsp) cold water to make a smooth, lump-free slurry. Slowly pour the slurry into the simmering blueberry mixture, stirring constantly. Continue cooking over medium-low heat for 3 minutes, until the filling turns glossy and thick enough to coat the back of a spoon, with no cloudy white cornstarch streaks remaining. Remove the pan from heat.

Step 3
step3：Thicken the filling
4

Finish filling mixture

Stir 28g (2 tbsp) unsalted butter and 5ml (1 tsp) pure vanilla extract into the hot thickened blueberry mixture until the butter is fully melted and incorporated. Let the filling cool for 10 minutes at room temperature, then gently fold in the remaining 2 cups (225g) of fresh, uncooked blueberries to add firm texture and bright, fresh berry flavor.

Step 4
step4：Finish filling mixture
5

Assemble the pie

Pour the finished blueberry filling evenly into the fully cooled graham cracker crust, spreading it gently with a spatula to create a smooth, level top. Lightly tap the pie dish on the counter 2-3 times to release any trapped air bubbles in the filling that would cause gaps as the pie sets.

Step 5
step5：Assemble the pie
6

Chill and serve

Loosely cover the pie with plastic wrap and refrigerate for a minimum of 4 hours (or up to 24 hours for make-ahead prep) until the filling is fully firm and set. Slice into 8 equal wedges, and serve cold or at cool room temperature, optionally topped with freshly whipped cream or vanilla ice cream if desired.

Step 6
step6：Chill and serve

Tips

1.Press graham cracker crumbs very firmly and evenly across the bottom and up the sides of the pie dish; loosely packed crumbs will cause the crust to crumble apart when you slice the finished pie.
2.Resist the urge to stir all blueberries into the hot filling: folding in 2 cups of fresh, uncooked berries after cooling prevents mushy filling and adds bright, juicy pops of fresh berry flavor.
3.Do not cut the pie before it chills for the full 4 hours; warm, under-chilled filling will be runny and will not hold a clean, neat slice shape on plates.

Blueberry Pie with Graham Cracker Crust:Frequently Asked Questions

1.Can I use store-bought graham cracker crumbs instead of crushing whole crackers for the crust? ▾
Absolutely! Store-bought graham cracker crumbs are a huge time-saver and work perfectly for this crust, just double-check there are no added spices or extra sweeteners that throw off the flavor balance. If you crush your own, blitz whole crackers in a food processor or bash them in a sealed zip-top bag with a rolling pin until you have fine, even crumbs with no large chunks.
2.Do I need to pre-bake the graham cracker crust before adding the blueberry filling? ▾
Yes, a quick 10-minute pre-bake at 375°F is non-negotiable here. It sets the buttery crumb structure so your crust stays crisp instead of turning soggy once you add the juicy blueberry filling. Let it cool completely for at least 20 minutes before pouring in filling to avoid excess steam that can make the base mushy.
3.Can I use frozen blueberries instead of fresh for the filling? ▾
You can, but take a couple extra steps to avoid a runny pie. Thaw frozen blueberries completely first, then drain off all excess released juice before using them in the filling. Keep in mind frozen berries are often softer, so your filling will have a slightly more jammy texture than the bright, fresh bite you get with in-season summer blueberries.
4.Why does my graham cracker crust fall apart when I slice the pie? ▾
This almost always traces back to one of two issues: either you didn’t use enough melted unsalted butter to bind the crumbs, or you didn’t press the crumbs firmly and evenly into the pie plate before baking. Make sure crumbs are evenly coated in butter, pressed tight across the base and up the sides, and the baked crust cools fully before adding filling.
5.How do I keep my blueberry filling from turning out too runny? ▾
For a set, sliceable filling that isn’t gummy, toss 2/3 of your divided fresh blueberries with the granulated filling sugar and a small amount of cornstarch, then cook briefly to activate natural fruit pectin. Stir in the remaining 1/3 of fresh berries off heat for bright, juicy pops, and avoid over-stirring raw berries which releases extra juice.
6.Can I make this pie ahead of time for summer cookouts or gatherings? ▾
You absolutely can, which makes it ideal for the warm-weather gatherings this pie is made for. Bake the pie fully, let it cool completely to room temperature (this takes 3 to 4 hours, don’t rush it!), then cover loosely and store in the fridge for up to 2 days before serving. Skip freezing, as that makes the crust soggy and berries mushy.
7.Should I add extra seasonings or salt to the crust or filling? ▾
A tiny pinch of fine sea salt in both the graham cracker crust and blueberry filling goes a long way to amp up the buttery crust flavor and balance the sweet-tart pop of the blueberries, without tasting salty. You can add 1/4 teaspoon of lemon zest to the filling for extra brightness, but skip heavy spices like cinnamon that overpower fresh blueberry flavor.
8.How firmly do I need to press the graham cracker crumbs into the pie plate? ▾
Press firmly enough that the crumbs form a tight, even layer across the bottom and 1 inch up the sides of a standard 9-inch pie plate—you can use the flat bottom of a dry measuring cup to get a smooth, compact surface. Don’t press so hard that the crust oozes excess butter, but loose, unpacked crumbs will fall apart when sliced.
9.Can I use a sugar substitute to make a lower-sugar version of this pie? ▾
You can swap the granulated sugar in both the crust and filling for a 1:1 granulated baking sugar substitute, just note it may slightly alter filling texture, since sugar helps activate natural pectin in blueberries for a proper set. Taste your blueberries first—extra ripe, sweet berries work great with 2 tablespoons less sugar overall.
10.What’s the trick to getting clean, neat slices of this pie? ▾
For clean, picture-perfect slices, let the baked pie chill in the fridge for at least 2 hours after it cools to room temperature first. Dip a sharp, thin-bladed knife in hot water, wipe it dry between each cut, and slice slowly through the firm crust and set filling. Avoid sawing back and forth, which tears the crust and smushes berries.
11.Do I need to use pie weights when pre-baking the graham cracker crust? ▾
No, you don’t need pie weights for a graham cracker crust! Unlike flaky pastry crusts that puff up while baking, graham cracker crumbs bound with melted butter stay compact as long as you pressed them firmly into the plate before baking. Just pop the pressed crust straight in the oven for that short pre-bake, no parchment or weights required.
12.Why did my blueberry filling turn out thick and gummy instead of juicy? ▾
That gummy texture almost always comes from adding too much thickener, or cooking the blueberry filling for too long on the stove. Remember, blueberries have natural pectin that helps set the filling as it cools, so only use a small amount of cornstarch, and cook the base berry mixture just long enough for the granulated sugar to dissolve and berries to start softening.

Super easy recipe, turned out great for my first ever homemade pie! I used fresh wild blueberries I picked on a hike last weekend and it tasted like summer in a slice. Only note is I added a tiny extra squeeze of lemon to the filling because I love that zing, worked perfectly.

My kids devoured half this pie in 10 minutes flat after dinner last night. I love that it doesn’t require any fancy pastry skills, because rolling out pie dough stresses me out so bad. The graham cracker crust is foolproof!

5 days ago

Made this for my weekly meal prep to have as a little weeknight treat and it held up perfectly in the fridge for 4 days! Not too sugary, which I really appreciate—so many blueberry pie recipes are cloyingly sweet, this one is just right.

Game changer to use graham cracker crust for blueberry pie! I always thought you needed a traditional flaky crust, but this is way faster and honestly tastes better. Topped mine with a little whipped cream and fresh berries when I served it to my roommates, they thought I bought it from a fancy bakery.

yesterday

Solid easy recipe, came together in under an hour which was perfect because I forgot I was supposed to bring dessert to my golf league dinner until an hour before I had to leave. Everyone raved, nobody guessed it was a last minute throw together.

Wait, can I use frozen blueberries for this? I have a giant bag in my freezer I’ve been trying to use up and I don’t feel like running to the grocery store today.

30 minutes ago

Great question! Frozen blueberries work totally fine here—just let them thaw completely and drain off any excess liquid before tossing them with the filling ingredients to keep your pie from getting soggy. Happy baking!

I made this yesterday for my Sunday family dinner and my mother in law, who is literally the pickiest eater on the planet, asked for a second slice! I was so proud, I thought for sure she’d find something to complain about.

Omg same! My MIL is impossible to impress with desserts and she went back for thirds when I made this last month. I added a little cinnamon to the graham cracker crust and it was chef’s kiss

How long does this keep in the fridge? I want to make it a day ahead for my friend’s birthday cookout so I don’t have to rush around the day of.

2 days ago

You can absolutely make this a day ahead! It will stay fresh covered in the fridge for up to 5 days, so making it the night before your event works perfectly (and actually gives the flavors extra time to meld together!).

30 minutes ago

Wait, do I have to chill it for the full 4 hours? I’m having people over in 2 hours and I’m tempted to stick it in the freezer to speed it up, has anyone tried that?

5 minutes ago

I did that last time! Popped it in the freezer for 90 minutes and it set totally fine, just don’t leave it in there too long or it’ll get icy on top. Worked like a charm for my last minute game night!

This was so easy even I didn’t mess it up, and I burn toast 90% of the time. The cook time is totally accurate too, I didn’t have to add any extra time in my oven which is always a win because my oven runs super hot.

So happy to hear it turned out well for you! If your oven runs hot, you can always tent the crust with a little foil halfway through baking if you notice it browning too fast, but it sounds like you nailed it this time!

I added a crumb topping to mine instead of leaving it plain and it was *chef’s kiss*. The graham cracker crust plus extra buttery crumbs on top? Total comfort food. Will be making this every Fourth of July from now on.

Oh that’s such a good idea! I was thinking about adding a streusel top when I make this for our Fourth of July party next weekend, glad to hear it works well with the recipe.

Took this to a work potluck and it was gone in literally 5 minutes. I had three people Slack me the rest of the day asking for the recipe, I felt like a celebrity. The easy difficulty rating is no joke, even a beginner can nail this.

Love that it was such a hit at your work potluck! Nothing beats a low-effort dessert that wows a crowd, right? Thanks for leaving such a nice note!

I don’t have a graham cracker crust pre-made, and I’m out of graham crackers—would vanilla wafers work as a substitute for the crust?

5 minutes ago

I used vanilla wafers for the crust last week when I ran out of graham crackers and it was amazing! Just crush them up the same way you would graham crackers, mix with melted butter and sugar, it comes out perfect.

just now

Vanilla wafers make a fantastic crust swap! You can also use gingersnaps if you want a little warm spice in the crust, both work great with the blueberry filling. No need to run to the store!

Made this for our college football tailgate last weekend and it was a total hit. Wait, has anyone tried making this with other berries? I’m thinking of doing a mix of blueberries and raspberries for the next tailgate.

5 days ago

I did half blueberries half strawberries last time and it was so good! Just make sure you cut the strawberries into small pieces so they cook down the same as the blueberries, no other changes needed.

3 days ago

Mixed berries work beautifully in this recipe! Raspberries, blackberries, even chopped strawberries all pair perfectly with the simple filling and graham cracker crust. It’s a super flexible base recipe, so feel free to mix and match what you have on hand.

Wait, the recipe says 45 minutes cook time—does that include preheating the oven? I’m always confused about whether cook times count preheat, because my oven takes forever to heat up.

yesterday

I was wondering the same thing last time I made it! The 45 minutes is just the bake time, so budget an extra 10-15 minutes for your oven to preheat before you pop the pie in. I almost messed that up too!

yesterday

Great catch! The 45 minute cook time is active baking time, so you’ll want to plan for extra time to preheat your oven (usually 10-15 minutes, depending on your model) before putting the pie in. Hope that helps!

3 days ago

This pie is SO good, but my crust got a little soggy the first time I made it. Any tips to keep the graham cracker crust crisp when it’s sitting with the filling?

2 days ago

I had that problem the first time too! Now I blind bake the crust for 10 minutes before adding the filling, and let it cool completely, and it stays crisp the whole time. Total game changer.

yesterday

Blind baking the crust for 8-10 minutes at 375F before adding the filling is the perfect fix for a soggy crust! Also make sure you’re draining any excess juice from your blueberries if they’re extra ripe or frozen/thawed, that extra liquid can seep into the crust and make it soft too.

Made this last night for date night and my partner said it’s the best dessert I’ve ever made. I will say I added a little lemon zest to the filling and it really brightened up the blueberry flavor so much, 10/10 recommend.

3 days ago

Omg I added lemon zest too! I also put a tiny bit of almond extract in the filling, it adds such a nice warm depth that pairs so well with blueberries. You have to try it next time!

2 days ago

Lemon zest is such a great addition—that bright, citrusy note cuts through the sweetness perfectly! Almond extract is another fantastic add-in, we love hearing all the fun customizations folks are making to the recipe.
