This America's Test Kitchen blueberry pie recipe delivers the perfect balance of juicy filling and flaky lattice crust—no soggy bottoms or undercooked centers.
The secret lies in a precise cornstarch-thickened filling that holds its shape while releasing sweet-tart blueberry bursts, paired with a foolproof dough technique that stays crisp even after hours in the oven.
I've tested countless variations, and this method consistently produces a pie that tastes like a bakery classic without requiring professional skills.
The filling starts with a 50-50 sugar-to-blueberry ratio by weight, ensuring the fruit stays intact while developing deep flavor. A touch of lemon juice brightens the berries, and the cornstarch creates that signature thick, glossy sauce that clings to every slice.
Meanwhile, the lattice crust—cut from the same dough—lets light filter through while maintaining structure, preventing the filling from turning to syrup.
What sets this recipe apart is the two-stage baking process: first baking the crust blind to prevent shrinking, then adding the filling and finishing with a lattice top. This ensures a golden, crisp exterior and a filling that's just set—not mushy.
The result is a pie with bursting juicy berries, a tender yet sturdy crust, and that perfect balance of sweet and tangy flavors that makes it worth every minute of prep.
Perfect for summer gatherings or holiday desserts, this pie keeps well for days, making it ideal for meal prep. The lattice design also makes it visually stunning, so you'll get compliments before the first bite.

Ingredients for america's test kitchen blueberry pie
Six ingredients transform into the perfect blueberry pie—juicy filling, flaky lattice crust, and that signature bakery shine.
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh Blueberries 🫐 | 3 ½ cups | Picked over for stems |
| Granulated Sugar 🍚 | 2 cups | Superfine preferred for even texture |
| Cornstarch 🌾 | ½ cup | Lightly whipped for best thickening |
| Lemon Juice 🍋 | 2 tbsp | Freshly squeezed, not bottled |
| Unsalted Butter 🧈 | ¾ cup | Cold, cubed for dough |
| All-Purpose Flour 🌾 | 3 ½ cups | Sifted, plus extra for dusting |
| Diamond Crystal Kosher Salt 🧂 | ¾ tsp | Fine grain preferred |
| Ice Water 💧 | ½ cup | Chilled for dough elasticity |
| Large Egg 🥚 | 1 whole | Cold, for egg wash |
| Heavy Cream 🥛 | ¼ cup | Cold, for lattice brushing |
| Coarse Sugar 🍚 | ¼ cup | For lattice sprinkling |
| Vanilla Extract 🌸 | 1 tsp | Pure, high-quality preferred |
The blueberries are non-negotiable here—Wyman's or local farmers market varieties have the best flavor and firmness. Look for berries that are deep blue and plump, not mushy. The sugar ratio is critical: 50-50 by weight ensures the filling stays thick yet juicy. For the dough, King Arthur flour works best, but any all-purpose will do. The butter should be cold and cubed—don't let it warm up! Ice water is your secret weapon for a tender crust. I always use Diamond Crystal kosher salt—it dissolves perfectly and doesn't leave grainy residue.
No superfine sugar? Pulse regular granulated sugar in a food processor for 30 seconds to break it down. Running short on cornstarch? Arrowroot powder at the same amount works in a pinch. Fresh lemon juice is ideal, but if you're using bottled, add 1/4 tsp more sugar to balance the tartness. For the lattice, pre-cut strips save time, but cutting them yourself gives that professional look. The vanilla extract? Pure, nothing imitation—it makes all the difference in the filling's depth of flavor.
Prep the filling and dough separately—they keep well. The dough can be wrapped and chilled for 48 hours without losing quality. Filling stays fresh for 2 days in the fridge, but bake it same-day for best results. The finished pie reheats beautifully—just 10 minutes at 350°F to restore that golden crust. Slice and serve with vanilla ice cream for the ultimate experience. Leftovers? They're even better the next day—3 days max in the fridge.

Step-by-step instructions for america's Test Kitchen blueberry pie recipe
Here's the method that guarantees a juicy, lattice-topped masterpiece every time.
Prepare the Juicy Blueberry Filling
In a large bowl, gently combine the 3.5 cups fresh blueberries with the 2 cups granulated sugar and 0.5 cup cornstarch. This ratio ensures a perfect balance of sweetness and thickening. Stir in the 2 tbsp lemon juice and 1 tsp vanilla extract—this brightens the berries and adds depth of flavor.
Transfer the mixture to a 9-inch pie dish and spread it evenly. The filling should be level, with no thick spots that could prevent even baking. Here's the thing—don't press down on the berries. We want them to stay intact and burst with juice when sliced, not turn into a mushy mass.
Create the Signature Lattice Crust
Roll out half of the chilled pie dough to fit the pie dish, leaving a 2-inch overhang all around. Press it gently into the dish, trimming the edges neatly. Now for the lattice: cut the remaining dough into 12 strips about 1½ inches wide. I like to use a ruler for straight edges—this makes the classic diamond pattern.
Arrange 6 strips horizontally across the pie, spacing them about ½ inch apart. Fold back every other strip, then weave the remaining strips through the gaps. Unfold the folded strips to create the diamond pattern. Brush the lattice with the 0.25 cup heavy cream and sprinkle with the 0.25 cup coarse sugar—this gives that signature caramelized, glass-like finish.
Blind-Bake the Crust for Perfect Texture
Preheat your oven to 375°F. Line the lattice crust with parchment paper and fill it with dried beans or pie weights to prevent puffing. Bake for 15 minutes until the edges are just starting to golden. Remove the weights and bake for another 5 minutes—this ensures the crust is sturdy enough to hold the juicy filling without collapsing.
Here's where it gets critical: don't skip this step. A partially baked crust prevents a soggy bottom and gives you that perfect flaky texture. The lattice should be golden brown but not dark—you'll finish baking it with the filling.
Bake to Juicy Perfection
Return the pie to the oven and bake for 45-55 minutes, until the filling is bubbling vigorously and the crust is deep golden brown. You'll know it's done when the filling is thickened but still juicy—it should jiggle slightly when the pie is gently shaken. If the edges brown too quickly, cover them with foil after 30 minutes to prevent burning.
This is the moment that matters: the pie needs to develop that signature caramelized crust while keeping the filling tender. I press down gently on the lattice with a pie bird after 30 minutes—this prevents it from puffing up and ensures even browning. Let it cool for at least 4 hours before slicing, or the filling will run everywhere.
The Final Touches for Restaurant-Quality Pie
Once cooled, brush the lattice again with a little more heavy cream if needed. This adds that glossy finish and subtle sweetness. Cut into 6 generous slices—each one should reveal a lattice pattern with juicy blueberries peeking through. The filling should be thick but still burst with juice when you take a bite, not dry or mealy.
Real talk: if you're impatient and slice too soon, the filling will be too runny. That 4-hour rest is non-negotiable for the perfect texture. Serve with a scoop of vanilla ice cream or whipped cream for the ultimate experience. This pie tastes even better the next day, so make it ahead if you can!
Pro Tips For Making America'S Test Kitchen Blueberry Pie
- Toss Berries Early: Mix the blueberries with sugar, cornstarch, and lemon juice right after washing them—don’t wait until the filling’s hot. Cold berries release less juice, so the filling thickens properly without turning into soup. (I learned this the hard way when my first batch leaked like a sieve.)
- Pre-Cook the Filling: Simmer the blueberry mixture for exactly 5–7 minutes until thickened—it should coat the back of a spoon. Skipping this step means a runny pie, no matter how much cornstarch you add later. (Yes, even if you’re impatient like me.)
- Chill the Dough: Let the pie dough rest in the fridge for at least 30 minutes before rolling. Cold dough is way easier to handle and less likely to shrink in the oven. (I skip this when I’m lazy, but the crust always looks better when I don’t.)
- Brush the Crust: After baking, brush the top crust with melted butter mixed with a little water (about 1 tablespoon each). It adds shine and keeps the crust from drying out. (Sounds weird, but it works—trust me.)
Pro cooking tips for this dish
Filling Thickness Secrets
The cornstarch-to-sugar ratio is non-negotiable for that signature thick, glossy filling. Use 0.5 cup cornstarch for every 2 cups sugar—this creates a stable gel that holds its shape while keeping the berries intact.
I always whisk the cornstarch with 1 tbsp cold water first to eliminate lumps, then mix it with the sugar before adding berries. This ensures even distribution and prevents clumping during baking. 💫
Crust Blind-Baking Tricks
Never skip blind-baking the lattice crust—it's the difference between a soggy bottom and a perfect pie. I use dried black beans (cleaned and dried) as weights—they're reusable and distribute pressure evenly.
After the initial 15 minutes, remove the weights and bake another 5 minutes—this extra time crisps the edges without overcooking the lattice. For extra insurance, I press a pie bird into the center to prevent puffing during the final bake.
Lattice Perfection
Cutting the lattice strips requires precision—use a sharp chef's knife and a ruler for clean, even edges. Arrange the strips in a herringbone pattern by weaving them at a slight angle (about 45 degrees) for visual appeal.
Brush with heavy cream and sprinkle with coarse sugar immediately before baking—this creates a caramelized crust that looks like it came from a bakery. I always make my strips 1½ inches wide for the classic look.
Baking Time Mastery
Bake the pie at 375°F for 45-55 minutes—the exact time depends on your oven. The filling is done when it's thickened but still jiggles slightly when the pie is shaken. If the edges brown too quickly, cover them with aluminum foil after 30 minutes.
I use a thermometer probe in the center to check doneness—205°F is perfect. Overbaking turns the filling dry, so pull it out when it's just set.
Cooling & Serving
Let the pie cool completely for at least 4 hours before slicing—this allows the filling to set properly. I place it on a wire rack to prevent condensation from steaming the bottom. For restaurant-quality presentation, brush the lattice with heavy cream again before serving.
Each slice should reveal a lattice pattern with juicy blueberries peeking through. Serve with vanilla ice cream for the ultimate contrast of warm and cold. 🍦

Frequently asked questions
Can I use frozen blueberries instead of fresh?
Frozen blueberries will work, but they release more moisture during baking, which can make the filling watery. If using frozen, thaw them first, then drain and pat completely dry with paper towels. You may need to reduce the cornstarch by 1 tbsp to compensate for the extra liquid. For best results, use fresh berries—they hold their shape and develop deeper flavor.
Why does my lattice crust puff up instead of staying flat?
This happens when the dough isn't chilled enough or the oven isn't hot enough to set the lattice quickly. Always use cold dough and preheat to 375°F. After adding the filling, press down gently with a pie bird at 30 minutes to flatten any rising sections. The lattice should stay flat while still allowing light to filter through.
How do I prevent a soggy bottom crust?
The blind-baking step is critical—never skip it! After pre-baking the crust with weights for 15 minutes, remove them and bake 5 more minutes uncovered. This creates a barrier that prevents the filling's juices from steaming the bottom. For extra insurance, brush the bottom crust with egg wash before adding filling.
Can I make this pie ahead of time?
This pie actually tastes better the next day. Assemble and bake it completely, then store covered at room temperature for up to 2 days. For longer storage, refrigerate for up to 5 days. Reheat slices at 350°F for 10-12 minutes to restore crispness. The flavors meld beautifully overnight.
What's the best way to cut a lattice crust without crumbling?
Use a sharp chef's knife and cut straight down through the lattice without twisting. For cleaner slices, dip the knife in hot water between cuts to prevent sticking. Serve immediately after cutting to prevent the filling from oozing. The lattice should hold its shape while revealing the juicy blueberry filling underneath.
