10-Inch Rhubarb Pie Recipe: Tart-Sweet Balance With Crispy Lattice Top

This 10-inch rhubarb pie recipe delivers the perfect balance of tart rhubarb and sweet filling, topped with a golden, crispy lattice crust that's worth every bite. The secret lies in pre-cooking the rhubarb to soften it just enough while preserving its signature tang—no mushy fillings here.

I've perfected this technique over years of baking, ensuring the crust stays flaky and the filling holds its shape until that first forkful.

The recipe starts with a classic double-crust pie, but the lattice design (cut from a single sheet) creates stunning visual appeal while allowing the filling to breathe.

A simple sugar-spice blend—just sugar, cornstarch, and a pinch of cinnamon—transforms tart rhubarb into a harmonious filling that's neither too sweet nor too sour. Baking at 375°F for 50-55 minutes ensures a perfectly set filling with a caramelized top.

What sets this pie apart is the crispy lattice crust that stays sturdy even when sliced, paired with a filling that's just firm enough to hold its shape. The pre-cooking step prevents a soggy bottom while concentrating the rhubarb's natural flavors.

Whether you use a homemade crust or store-bought, the result is a pie that tastes like summer—bright, balanced, and impossible to resist.

Serve it warm with vanilla ice cream or whipped cream for the full experience. The lattice pattern isn't just decorative—it creates pockets of air that keep the pie light and flaky. Here's how to make it shine.

Ingredients for 10 inch rhubarb pie

Tart rhubarb, flaky crust, and a lattice top that stays crispy—just eight ingredients for summer's best pie.

The rhubarb is non-negotiable—bright pink stalks with no green or tough parts. Local farmers markets often have the freshest, most vibrant stalks in early summer. Trim the ends and chop into even 1-inch pieces for consistent cooking. If using store-bought, check for firmness—soft spots mean it's past its prime. For the crust, King Arthur flour works beautifully, but any all-purpose will do. Chill your butter for at least 30 minutes before mixing to ensure a flaky texture.

No cornstarch? Arrowroot powder at the same amount works just as well. The cinnamon adds warmth without overpowering the rhubarb's natural tartness—Penzeys brand has excellent quality if you want to splurge. For the lattice, cut the dough into strips about 0.5 inches wide—use a pizza cutter for clean edges. If you're short on time, a pre-made pie crust from Whole Foods or Trader Joe's saves 45 minutes of work without sacrificing quality. The egg wash? Just the yolk—it gives that golden sheen without making the crust soggy.

Pre-cook the rhubarb mixture to concentrate flavors—10 minutes on medium heat is perfect. Store any leftover filling in an airtight container for up to 3 days in the fridge. The baked pie reheats beautifully in a 350°F oven for 10 minutes if you want to serve it warm. For the lattice, assemble it right before baking to prevent sogginess. The crust stays crisp for 3 days at room temperature if stored in a cool, dry place—just cover it loosely with parchment.

Step-by-step instructions for 10-Inch rhubarb pie

Here's how to create a perfect tart-sweet rhubarb pie with a golden lattice crust.

In a large mixing bowl, combine the 1 cup unsalted butter (cold and cubed) with the 1 cup all-purpose flour and 0.5 teaspoon salt. Using a pastry cutter or your fingers, work the butter into the flour until the mixture resembles coarse crumbs with pea-sized butter pieces remaining.

Gradually add the 0.5 cup ice water, 1 tablespoon at a time, mixing gently with a fork until the dough just comes together. Be careful not to overmix—just until the dough holds when pressed. Shape the dough into a disk, wrap in plastic, and refrigerate for at least 30 minutes while you prepare the filling.

In a large bowl, combine the 4 cups fresh rhubarb stalks (chopped into 1-inch pieces) with the 1.5 cups granulated sugar, 2 tablespoons cornstarch, and 0.5 teaspoon ground cinnamon. Mix gently but thoroughly to distribute the sugar evenly—this prevents a filling that's too sweet in some spots and tart in others.

Transfer the rhubarb mixture to a 6-quart saucepan and cook over medium-high heat for 8-10 minutes, stirring frequently, until the rhubarb softens and the mixture thickens to a jam-like consistency. The filling should coat the back of a spoon when you lift it out. Remove from heat and let cool completely before filling the pie.

On a lightly floured surface, roll out half of the chilled pie dough to a 12-inch circle (about ⅛-inch thick). Transfer the dough to a 10-inch pie dish, pressing gently to shape it to the bottom and sides. Trim any excess dough hanging over the edge, leaving about ½-inch for crimping later.

Pour the cooled rhubarb filling into the crust, mounding it slightly in the center. Roll out the remaining dough to another 12-inch circle. Cut the dough into ½-inch wide strips, leaving some strips slightly longer than others for visual interest in the lattice pattern.

Arrange the strips in a crisscross pattern over the filling, starting with a full strip across the top. Weave the next strip under and over the first, then add another full strip perpendicular to create the classic lattice design. Press the edges of the lattice onto the filling to seal, then crimp the outer edge of the crust with the remaining dough trimmings.

Brush the lattice top with the 1 whole egg yolk mixed with 1 tablespoon water for a golden finish. Cut several small slits in the lattice to allow steam to escape during baking. Place the pie on a baking sheet to catch any drips.

Preheat your oven to 375°F. Bake the pie for 45-50 minutes until the crust is deep golden brown and the filling is bubbling through the lattice openings. The filling should be thick enough to hold its shape when the pie is done.

Remove from the oven and let cool for 2 hours before slicing. This resting time allows the filling to set properly and prevents a runny pie. Serve warm with 1.5 cups vanilla ice cream for the perfect balance of tart and sweet.

Flavor customization for this dish

Sweet-Tart Balance

Adjust the sugar-to-rhubarb ratio to suit your taste—try 1:1.25 for extra tartness or 1:1.5 for a sweeter profile. I often start with 1.5 cups sugar but reduce to 1.25 cups if using very ripe rhubarb.

For a subtle depth, add ¼ tsp vanilla extract or 1 tsp lemon zest to the filling while pre-cooking. 💫

Spiced Variations

Swap the cinnamon for ½ tsp cardamom or ¼ tsp nutmeg for a Middle Eastern twist. A pinch of black pepper (just ⅛ tsp) adds complexity without overpowering. For warmth, try ½ tsp ginger or ¼ tsp cloves—both work beautifully with rhubarb’s natural tang.

Fruit Add-Ins

Add 1 cup diced strawberries or ½ cup blueberries to the filling for a berry-rhubarb fusion. Toss them in 1 tsp lemon juice before adding to prevent sinking. For a tropical touch, use ½ cup diced mango—its sweetness balances rhubarb’s acidity perfectly.

Crust Twists

Replace the classic crust with a graham cracker crust for a nutty contrast or a gingersnap crust for spiced depth. For extra flakiness, add 1 tbsp cold milk to the dough. A shortbread crust (butter + sugar + flour) adds buttery richness that pairs wonderfully with tart filling.

Glaze Finishes

Drizzle the cooled pie with a simple glaze made from ½ cup powdered sugar and 1 tbsp lemon juice. For extra shine, add 1 tsp honey or ½ tsp vanilla extract.

A white chocolate ganache (melt ½ cup white chocolate with 2 tbsp cream) adds a luxurious touch.

Dietary Swaps

For gluten-free, use a 1:1 gluten-free flour blend (like Bob’s Red Mill) and add ¼ cup cornstarch to the dough. For vegan, replace butter with ½ cup coconut oil (solid) and use flax egg (1 tbsp ground flax + 3 tbsp water) for the wash.

The filling stays the same—rhubarb’s tartness shines in all versions! 🌱
