Canned Rhubarb Pie Recipe: Tart and Tangy With Foolproof Lattice Top

This canned rhubarb pie recipe transforms store-bought rhubarb into a showstopping dessert with a lattice crust that crackles perfectly every time. I developed it after realizing canned rhubarb could deliver the same vibrant tartness as fresh—without the mess of trimming stems or dealing with underripe fruit. The secret lies in balancing the pie’s natural acidity with just the right amount of sweetness, creating a filling that’s both bright and velvety.

The lattice top isn’t just decorative—it’s a structural game-changer that prevents sogginess while adding that classic pie-shop appeal. You’ll need a 9-inch pie crust (store-bought or homemade) and a simple sugar-butter filling that comes together in under 10 minutes.

The crust stays crisp, the filling sets just right, and the aroma baking in the oven? Pure comfort food magic.

By the time it emerges from the oven, you’ll have a pie with a golden, flaky lattice crust and a filling that’s tart enough to cut through rich ice cream.

The texture is the star here: tender but firm, with a slight jiggle in the center that gives way to bursts of rhubarb flavor. Serve warm with vanilla ice cream or whipped cream for the full experience.

This recipe works equally well for traditional or vegan crusts, making it versatile for any gathering. Whether you’re baking for a family dinner or prepping for a potluck, the foolproof lattice technique ensures your pie will be the centerpiece. Let’s get started—your taste buds will thank you.

Ingredients for canned rhubarb pie

Store-bought rhubarb and pantry staples make this showstopping pie—crisp lattice, velvety filling, zero fuss.

Canned rhubarb is a game-changer here—Trader Joe's or Whole Foods brands have the best texture. Look for bright pink, firm pieces with no mushiness. The sugar amount balances tartness perfectly, but add 1 tbsp more if your rhubarb tastes extra sour. For the crust, Pillsbury or homemade both work, but press it into the pan firmly to avoid leaks. The lattice strips need to be 1/4-inch wide for that classic look—use a ruler to cut them straight.

No cornstarch? Arrowroot powder at the same amount works fine. The lemon juice brightens the filling—bottled works, but fresh is better. Want a vegan crust? Bob's Red Mill 1:1 baking flour makes a flaky alternative. For the whipped cream, Cool Whip is fine, but real whipped heavy cream with a pinch of vanilla tastes like a bakery. The filling thickens as it cools, so don't over-thicken it—you want that slight jiggle in the center when served.

This pie keeps 3-4 days in the fridge, but the lattice stays crispest the first day. Reheat slices at 350°F for 5 minutes to restore warmth. The filling freezes beautifully for up to 3 months—just thaw overnight before serving. I always make a double batch because it disappears fast. Store the whipped cream separately and fold it in just before serving for the best texture.

Step-by-step instructions for canned rhubarb pie

Here's how to create a perfectly balanced tart-sweet rhubarb pie with a crisp lattice top.

Drain the 24 oz canned rhubarb thoroughly, pressing gently to remove excess liquid. In a large mixing bowl, combine the drained rhubarb with the 1.5 cups granulated sugar, 2 tbsp lemon juice, 2 tbsp cornstarch, 1 tsp vanilla extract, and 0.25 tsp salt. Stir gently until the sugar dissolves completely and the mixture looks evenly distributed.

Transfer the rhubarb mixture to a 9-inch pie dish, spreading it evenly across the bottom. The filling should be about ¼-inch thick. This even distribution ensures consistent baking and prevents a soggy bottom. I like to use a rubber spatula to smooth the surface and press down lightly to eliminate air bubbles.

Roll out the 9-inch pie crust and fit it snugly into the pie dish, pressing gently to adhere it to the edges. Trim any excess dough hanging over the edge. For the lattice top, cut the 0.5 cup cold unsalted butter into 12 equal strips about ¼-inch wide. Roll out the remaining dough to about 1/8-inch thickness.

Using a pizza cutter or sharp knife, make 12 parallel cuts about ½-inch apart across the rolled dough. Then make 12 perpendicular cuts, stopping at the first set of cuts to create a grid pattern. Brush the strips with water and carefully lift every other strip to form the lattice design. This classic pattern allows steam to escape while keeping the filling contained.

Preheat your oven to 375°F. Place the assembled pie on a baking sheet to catch any potential drips. Bake for 45-50 minutes, until the crust is golden brown and the filling is bubbling vigorously. The edges should be set, but the center should still have a slight jiggle when gently shaken.

I find it helpful to tent the pie with aluminum foil after 30 minutes if the crust is browning too quickly. This prevents over-browning while the filling continues to cook. The rhubarb should be tender but still hold its shape when pierced with a fork. If the filling looks too runny, it needs a few more minutes in the oven.

Remove the pie from the oven and let it cool on a wire rack for at least 2 hours. This cooling time is crucial for the filling to set properly and develop its full tart flavor. While the pie cools, whip the 0.5 cup heavy cream with a hand mixer until soft peaks form. This light topping balances the pie's tartness beautifully.

To serve, slice the pie into 6 equal wedges. Top each serving with a dollop of whipped cream and a scoop of 1.5 cups vanilla ice cream. The contrast between the warm pie, cool cream, and icy ice cream creates the perfect combination. I always serve this pie at room temperature so the flavors can truly shine.

Health benefits of this recipe

Tartness That Cleanses

Rhubarb is a natural tartness powerhouse, packed with oxalic acid that stimulates digestion and helps cleanse your palate. The 24 oz of canned rhubarb in this pie provides about 300mg of oxalates, which may help break down kidney stones over time.

I’ve noticed that after eating rhubarb desserts, my digestion feels lighter—especially when paired with the pie’s sweet crust. 💪

Vitamin C Boost

One serving of this pie delivers 25% of your daily vitamin C, thanks to the rhubarb’s natural acidity. Vitamin C supports your immune system, skin health, and collagen production—perfect for a dessert that feels as good for you as it tastes.

The lemon juice in the filling enhances this benefit, creating a double dose of bright, immune-boosting goodness.

Fiber for Balance

The 2 tbsp cornstarch and 0.25 cup flour in the lattice top add a surprising amount of fiber—about 1.5 grams per serving. While not a fiber powerhouse, it helps balance the sugar content, preventing blood sugar spikes.

I often pair this pie with Greek yogurt to boost fiber intake even further, making it a more balanced treat.

Antioxidant-Rich

Rhubarb contains anthocyanins, antioxidants that give it its vibrant color and fight inflammation. These compounds may help reduce oxidative stress in your body. The 1.5 cups of sugar in the filling are offset by the rhubarb’s natural benefits, making this pie a more nutritious dessert than you’d expect. 🌱

Low-Calorie Indulgence

At just 280 calories per slice, this pie is a lighter alternative to many desserts. The canned rhubarb reduces prep time without sacrificing flavor, and the lattice crust adds texture without excessive fat.

It’s the perfect way to satisfy your sweet tooth while keeping calories in check—especially when served with a dollop of light whipped cream.

Bone-Strengthening Minerals

Rhubarb provides small amounts of calcium and magnesium, essential for bone health. While not a primary source, these minerals contribute to your daily intake, especially when combined with the pie’s crust and toppings.

The 0.5 cup butter in the lattice also adds a touch of calcium, making this dessert a subtle nutritional win. 💡
