10-Inch Rhubarb Pie Recipe: Tart Zing and Buttery Lattice Magic

This 10-inch rhubarb pie recipe delivers the perfect balance of tart rhubarb and buttery lattice crust that becomes the star of any dessert table.

The secret lies in a flaky, all-butter crust that holds its shape while baking, paired with a filling that's just sweet enough to complement the rhubarb's natural tang.

I've perfected this recipe over years of testing, ensuring the lattice isn't just decorative but functional—creating crispy, golden edges that contrast beautifully with the tender filling.

The filling transforms tough rhubarb stalks into a velvety, jam-like consistency thanks to a precise sugar-to-rhubarb ratio and a touch of cornstarch for thickening. This isn't your grandmother's pie—it's a restaurant-quality dessert that stays fresh-tasting even after a few days.

The lattice crust isn't just about looks; it creates those signature crispy pockets that make every bite exciting, while still letting the rhubarb's bright flavor shine through.

What makes this recipe truly special is how it comes together—no fancy techniques required, just patience and attention to detail. The crust gets its signature flakiness from cold butter cut into the flour, while the filling simmers just enough to develop its signature depth.

By the time it emerges from the oven, you'll have a pie with a golden, shatteringly crisp lattice crust and a filling that's perfectly set but still juicy.

Serve it warm with a scoop of vanilla ice cream or a dollop of whipped cream to balance the tartness, or enjoy it at room temperature for a pie that tastes even better the next day.

The lattice pattern isn't just for show—it creates those irresistible crispy edges that make this pie impossible to resist. Let's get started on creating your perfect rhubarb masterpiece.

Ingredients for 10 inch rhubarb pie

Buttery crust meets tart rhubarb perfection—eight ingredients for a showstopping dessert table centerpiece.

The rhubarb is non-negotiable—look for vibrant, firm stalks with no sliminess. Local farmers markets often have the freshest, brightest rhubarb, but the grocery store works too if you grab it early in the season. The sugar-to-rhubarb ratio is key here: too much sugar kills the tartness, too little leaves it underwhelming. I always use King Arthur flour for the crust—it gives that signature flakiness. If you're short on time, Trader Joe's sells pre-sifted flour in small bags that cut down on mess. The butter needs to be cold, so pull it straight from the fridge and let it sit for 30 minutes before cutting into cubes if it's been in the pantry too long.

No rhubarb? Substitute with tart cherries or gooseberries—they work surprisingly well. Running low on sugar? Honey or maple syrup at a 1:1 ratio adds depth, though the texture will be slightly different. The cornstarch is essential for that perfect set—don't skip it. For the crust, if you can't find vanilla extract, vanilla bean paste works too, though it's pricier. The egg wash is what gives that golden sheen—don't brush it too thinly, or you'll end up with pale lattice. And if you're making this ahead, make the crust first and freeze it wrapped in parchment—it'll be ready when you are.

This pie tastes even better the next day, so make it ahead if you can. Store the crust separately in the fridge for up to 3 days, and the filling can be prepped a day ahead—just bake it fresh. The finished pie keeps for 4-5 days at room temperature, wrapped tightly. For longer storage, freeze the whole pie (unwrapped) for up to 3 months. Just thaw it overnight in the fridge before serving. The lattice stays crispy if you reheat slices in the oven for 5 minutes at 350°F—perfect for serving with ice cream.

Step-by-step instructions for tart rhubarb pie with buttery lattice

Here's how to build a pie with bright rhubarb filling and a delicate, flaky lattice crust.

In a large bowl, combine the 4 cups chopped rhubarb stalks, 1.5 cups granulated sugar, 2 tbsp cornstarch, and 2 tbsp lemon juice. The sugar will begin to draw out the rhubarb's natural juices immediately—you'll see the mixture start to glisten. Let it sit for 10 minutes while you prepare the crust. This resting time helps the sugar dissolve completely and the cornstarch begin thickening.

Real talk: Don't skip the lemon juice. It balances the tartness and prevents the filling from becoming too acidic. If you're using older rhubarb, you might want to add an extra ½ tbsp of lemon juice—it's more likely to have developed a stronger flavor over time.

In a large mixing bowl, cut the 1 cup cold unsalted butter into the 2.5 cups all-purpose flour and ½ tsp salt using a pastry cutter or your fingers. Work quickly to keep the butter cold—this is key for flaky layers. You're looking for pea-sized butter pieces throughout the flour. Add the ½ tsp vanilla extract and mix just until combined.

Gradually add ¼ cup ice water, 1 tbsp at a time, mixing gently with a fork until the dough just comes together. It should hold when pressed but not be sticky. Divide the dough into two equal portions, flatten into discs, wrap in plastic, and refrigerate for at least 1 hour. This chilling step is non-negotiable—it prevents the crust from shrinking during baking.

Preheat your oven to 375°F. On a lightly floured surface, roll out one disc of dough to fit a 10-inch pie dish, about ⅛-inch thick. Transfer to the pie dish and trim the edges, leaving about ½-inch overhang. Roll out the second disc and cut into ½-inch strips for the lattice. Keep both dough pieces chilled until ready to use.

Press the bottom crust into the pie dish, making sure it covers the bottom and sides completely. Pour in the rhubarb filling, spreading it evenly. Here's the thing—don't pack it down. You want the filling to stay loose so it bubbles beautifully when baked. Arrange the lattice strips in a crisscross pattern over the filling, pressing gently at the intersections to seal.

In a small bowl, whisk together the 1 whole large egg, ¼ cup heavy cream, and a pinch of salt. This egg wash will give your lattice that gorgeous golden sheen. Brush it evenly over the lattice strips, making sure to get into all the crisscross intersections. Sprinkle any leftover sugar from the filling over the top—this creates those beautiful caramelized spots.

Bake on the middle rack for 45-50 minutes, until the lattice is deep golden brown and the filling is bubbling vigorously. The rhubarb should be tender when pierced with a knife but still hold its shape slightly. If the edges brown too quickly, cover them loosely with aluminum foil after 25 minutes. Let the pie cool completely before slicing—this prevents the filling from running out.

Once cooled, slice into 8 equal wedges using a sharp pie server. The lattice should be crisp but not brittle, and the rhubarb filling should be thick yet juicy with just the right balance of sweet and tart. Serve warm with a dollop of whipped cream if desired—though I prefer letting the pie's natural flavors shine.

This pie keeps well in the refrigerator for 3-4 days, though I doubt it'll last that long. The flavors actually improve slightly as the rhubarb's tartness mellows. Store any leftovers covered to maintain freshness. Enjoy every bite of that perfect balance between the buttery crust and vibrant filling!

Essential equipment for perfect results

Pie Dish Essentials

Start with a 10-inch glass or ceramic pie dish—glass conducts heat evenly, while ceramic adds a rustic touch. I recommend Pyrex for its durability and even baking.

If you prefer ceramic, look for Le Creuset or Corelle—both distribute heat well. Avoid dark-colored dishes as they absorb heat too quickly, causing uneven baking. 🍰

Crust Tools

A pie crust roller makes rolling dough easier, but a wooden rolling pin works just as well. For lattice precision, use a sharp chef’s knife or pizza cutter to cut clean strips.

I keep a bench scraper handy to transfer dough without tearing. A pastry brush (like OXO Good Grips) is perfect for egg wash application.

Measuring Precision

Accurate measurements are key—use a digital kitchen scale for butter and flour to avoid density errors. A fine-mesh sieve ensures even flour distribution for the lattice. For rhubarb prep, a mandoline or sharp chef’s knife cuts stalks uniformly. I swear by King Arthur Measure Up for precise liquid measurements.

Baking Gear

An oven thermometer (like Thermoworks) ensures your oven hits 375°F accurately—critical for lattice crispness. A pie cooling rack prevents soggy bottoms by allowing airflow. For lattice perfection, I use parchment paper to line the pie dish, making removal effortless.

A pie server with a sharp, serrated edge slices clean wedges every time.

Storage Solutions

Store leftovers in an airtight container with parchment between layers to maintain crispness. For freezing, wrap the whole pie in plastic wrap and foil—thaw overnight in the fridge. A vacuum sealer extends freshness for up to 3 months. I keep a pie carrier for easy transport to gatherings.
