Desserts
This 10-inch rhubarb pie recipe delivers the perfect balance of tart rhubarb and buttery crust, with a lattice top that adds rustic charm. The secret lies in stewing the rhubarb until tender—never mushy—and sweetening it just enough to let its natural tang shine through.
Whether you use a store-bought crust for convenience or roll out your own for that homemade touch, this pie is foolproof for any baker.
The filling starts with chopped rhubarb simmered with sugar and cornstarch until thick and glossy, while the lattice crust adds visual appeal and a satisfying crunch. Blind-baking the crust ensures a flaky base that won’t sog under the filling, a technique that elevates this pie from good to restaurant-quality.
Baking at 375°F for 45-50 minutes guarantees a golden, bubbling finish with edges that stay crisp.
What makes this recipe special is its versatility—serve it warm with vanilla ice cream for a classic pairing, or let it cool slightly for a firmer texture that’s perfect for slicing. The lattice isn’t just decorative; it creates pockets of air that keep the pie moist while adding texture.
For extra shine, brush the top with a simple corn syrup glaze before serving—it’s a pro trick that takes minutes but makes all the difference.
This pie is a showstopper for brunch gatherings, potlucks, or even a cozy weekend treat. The filling’s bright acidity cuts through rich desserts, making it a crowd-pleaser that feels both nostalgic and fresh.

Ingredients for 10 inch rhubarb pie
These ingredients create a perfect tart-sweet balance with a crisp lattice top.
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh Rhubarb Stalks 🍓 | 5 cups | Chopped into 1-inch pieces |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| Cornstarch 🌾 | ¼ cup | For thickening filling |
| Lemon Juice 🍋 | 2 tbsp | Freshly squeezed |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for crust |
| All-Purpose Flour 🌾 | 2 ½ cups | Plus 1 tbsp for dusting |
| Fine Sea Salt 🧂 | ½ tsp | For crust seasoning |
| Vanilla Extract 🌸 | 1 tsp | Pure vanilla preferred |
| Large Egg 🥚 | 1 whole | For egg wash |
| Corn Syrup 🍯 | 2 tbsp | For glaze |
| Heavy Cream 🥛 | ¼ cup | Optional for lattice |
The rhubarb is the star—look for vibrant pink stalks with no leafy green parts, which are bitter. Local farmers markets often have the freshest selection in early summer. Sugar content matters here; if your rhubarb tastes extra tart, bump it up to 1.75 cups. For the crust, store-bought pie crusts like Pillsbury or homemade rolled-out dough both work, but homemade gives that professional flakiness. Chill your butter before mixing to avoid a tough crust—30 minutes in the fridge does the trick.
No cornstarch? Arrowroot powder works at the same amount. Lemon juice can be swapped for white vinegar at half the quantity, but fresh lemon adds that bright pop. For the lattice, pre-cut strips from the grocery store save time, but cutting your own gives cleaner lines. The vanilla extract enhances the filling—imitation vanilla won’t cut it here. If you’re avoiding dairy, the heavy cream in the lattice can be replaced with coconut cream, though texture will differ slightly.
Store rhubarb stems in the fridge for up to 5 days—wrap them in a damp towel to keep them crisp. The crust can be prepped a day ahead and kept in the freezer. Once baked, pies reheat beautifully—10 minutes at 350°F revives that fresh-from-the-oven warmth. For extra shine, brush the lattice with corn syrup glaze right before serving—it sets quickly and adds that restaurant-quality finish. Leftovers keep for 4 days in the fridge or 2 months frozen.

Step-by-step instructions for 10-Inch rhubarb pie
This method delivers a perfect balance of tart rhubarb and sweet filling with a golden lattice crust.
Prepare the Rhubarb Filling
In a large mixing bowl, combine the 5 cups fresh rhubarb stalks (chopped into 1-inch pieces), 1.5 cups granulated sugar, 0.25 cup cornstarch, and 2 tbsp lemon juice. Stir gently to coat the rhubarb evenly. The sugar will begin to dissolve immediately, releasing juices that create a syrupy consistency.
Transfer the mixture to a medium saucepan and cook over medium-high heat, stirring frequently, until the filling thickens to a jam-like consistency (about 10-12 minutes). You'll know it's ready when the mixture coats the back of a spoon and bubbles steadily. Remove from heat and stir in the 1 tsp vanilla extract. Let it cool completely before filling the pie crust—this prevents the filling from cooking too quickly in the oven and turning mushy.
Make the Pie Crust and Assemble
In a large bowl, whisk together the 2.5 cups all-purpose flour, 0.5 tsp fine sea salt, and 0.5 cup cold unsalted butter (cut into small cubes). Use a pastry cutter or your fingers to work the butter into the flour until the mixture resembles coarse crumbs with pea-sized butter pieces. Add 0.25 cup heavy cream (if using) and mix gently with a fork until the dough just comes together.
Turn the dough onto a lightly floured surface and knead lightly for 2-3 minutes until smooth. Divide the dough into two equal portions, roll each into a 12-inch circle, and transfer one to your 10-inch pie dish. Trim and crimp the edges neatly. Pour the cooled rhubarb filling into the crust, mounding it slightly in the center.
Create the Lattice Topping
Roll out the second portion of dough into a 12-inch rectangle. Using a sharp knife or pizza cutter, make ½-inch vertical cuts down the rectangle, leaving ½-inch uncut strips between each cut. Then make ½-inch horizontal cuts perpendicular to the vertical cuts, stopping ½-inch from the ends to create a lattice pattern.
Gently lift every other vertical strip and fold it to one side, creating a classic lattice design. Carefully place the lattice over the rhubarb filling, pressing lightly to seal the edges. Brush the lattice with the 1 whole large egg beaten with 2 tbsp corn syrup for a glossy finish. This egg wash ensures a golden, crispy crust.
Bake to Golden Perfection
Preheat your oven to 375°F. Place the pie on a baking sheet to catch any drips and bake for 45-50 minutes, until the lattice is deep golden brown and the filling is bubbling gently. If the lattice browns too quickly, tent the pie with aluminum foil to prevent burning while it finishes baking.
Remove the pie from the oven and let it cool on a wire rack for at least 2 hours before slicing. This resting time allows the filling to set properly, ensuring clean slices with a perfect balance of tart rhubarb and sweet filling. Serve warm with vanilla ice cream for the ultimate dessert experience.
Pro Tips For Making 10 Inch Rhubarb Pie
- Trim Rhubarb Like a Pro: Cut the stalks into ½-inch chunks—no smaller, or they’ll turn to mush. I learned this the hard way after making a watery filling; thicker pieces hold their shape and thicken properly with the cornstarch.
- Simmer Until Syrupy: Cook the rhubarb-sugar mix over medium-high heat until it bubbles hard for 5 minutes, then reduce to medium-low. This drives off the sharpness and gets you that glossy, jam-like consistency—skimp on the time, and it’ll taste undercooked.
- Skip the Overmixing: Stir the cornstarch into cold water first, then whisk it into the hot filling once. Lumps are your enemy here, and once it’s in, don’t go back to stirring—just let it thicken on its own.
- Butter the Crust Early: Brush the pie crust with melted butter before adding the filling, not after. It creates a moisture barrier so the bottom doesn’t sog up—trust me, you’ll notice the difference when you pull it from the oven.
Make-ahead tips for 10 inch rhubarb pie
Prep Ahead
Make the crust up to 2 days ahead and store it in the fridge wrapped tightly in plastic. The filling can be prepped 1 day ahead and refrigerated in an airtight container. This is a lifesaver for busy mornings—just assemble and bake when ready. 📅
Freezer-Friendly
Assemble the pie completely (including the lattice) and freeze it unbaked for up to 2 months. Thaw overnight in the fridge, then bake as directed. The filling won’t release excess moisture during baking, so you won’t get a soggy crust. This trick ensures perfect texture even after freezing.
Filling Shortcut
Use 2 cups jarred rhubarb preserves instead of fresh rhubarb to save time. Simmer them with ½ cup water and 2 tbsp cornstarch for 5 minutes to thicken. This cuts prep time by 20 minutes while keeping the same great flavor. Just adjust sugar to taste—jarred preserves are often sweeter.
Lattice Prep
Cut the lattice strips 1 day ahead and store them between layers of parchment paper in the fridge. They’ll stay crisp and ready to assemble. For extra convenience, use pre-cut lattice strips from the grocery store—just brush with egg wash and place over the filling.
This saves 15 minutes of fussy cutting.
Bake Timing
Preheat your oven while the pie cools—this ensures even baking. If you’re short on time, bake the pie at 400°F for 35 minutes instead of 375°F, then reduce to 350°F for the final 15 minutes. This high-to-low method prevents over-browning while keeping the filling perfectly set. 🔥
Make It Ahead
The best pies actually taste better the next day! Cool completely, then store at room temperature for up to 4 hours or refrigerate for 3 days. Reheat slices at 350°F for 10 minutes to revive that fresh-baked flavor. This is perfect for potlucks—just reheat before serving.

Frequently asked questions
Can I use frozen rhubarb instead of fresh?
Frozen rhubarb works in a pinch, but it releases excess moisture when thawed, which can make your filling watery. If using frozen, thaw it completely, drain well, and pat dry with paper towels. You may need to reduce the sugar slightly (1.25 cups) since frozen rhubarb is often pre-sweetened. For best results, stick with fresh rhubarb when possible.
Why did my rhubarb filling turn mushy?
Mushy filling usually means the rhubarb wasn't cooked long enough or the filling was too hot when added to the crust. Always cool the filling completely before pouring it in, and cook it until it reaches a thick, jam-like consistency—it should coat the back of a spoon and bubble steadily. If it's still too thin, simmer for 2-3 more minutes.
Can I make this pie without a lattice top?
For a simpler top crust, roll out the second dough disk and place it over the filling, cutting 4-5 slits in the center to allow steam to escape. Crimp the edges and brush with egg wash. This creates a classic pie shape without the lattice effort. The filling will still bake beautifully—just watch for bubbles through the slits to check doneness.
How do I adjust the recipe for a 9-inch pie dish?
Reduce the rhubarb to 4 cups and the sugar to 1.25 cups. Use 2 cups flour for the crust and divide it into two 10-inch circles (one for the bottom, one for the top). Bake at 375°F for 35-40 minutes, as the smaller pie will cook faster. The lattice proportions stay the same—just scale down the strips accordingly.
What’s the best way to store leftover rhubarb pie?
Store at room temperature in an airtight container for up to 4 hours (great for same-day serving). For longer storage, refrigerate for 3-4 days or freeze for 2 months. To reheat, wrap slices in foil and warm at 350°F for 10-12 minutes—this restores the crust’s crispness and filling’s warmth.
