Rhubarb Pie Recipe Vegan: Tart-Sweet Balance Without Dairy

This vegan rhubarb pie delivers the perfect tart-sweet balance without any dairy or eggs—just rich, spiced rhubarb filling encased in a flaky vegan crust. 🌟 The secret lies in using a plant-based butter crust and a cornstarch-thickened filling sweetened with maple syrup, creating that signature rhubarb tang with a velvety texture.

I developed this recipe after struggling to find a vegan version that didn’t compromise on flavor or texture, and it’s now a crowd-pleaser at every gathering.

The crust gets its signature flakiness from a combination of vegan butter and cold flour, while the filling balances rhubarb’s natural tartness with just the right amount of sweetness.

Unlike traditional recipes, this version uses flaxseed as a binder in the filling, eliminating the need for eggs while maintaining that perfect set. The result is a pie that’s crisp on the edges, tender in the middle, and packed with that unmistakable rhubarb flavor.

What makes this recipe truly special is how it achieves restaurant-quality results with simple, plant-based ingredients. The crust holds its shape beautifully, and the filling stays thick and flavorful without becoming mushy.

The best part? It pairs perfectly with vegan whipped coconut cream for a light, creamy topping that complements the tart rhubarb.

Whether you're hosting a dinner party or just craving a classic dessert, this vegan rhubarb pie is sure to impress. The aroma alone will have everyone asking for seconds, and the texture is the perfect balance of crisp and tender. Here’s how to make it—no dairy or eggs required.

Ingredients for rhubarb pie recipe vegan

This vegan rhubarb pie needs just 14 ingredients—no dairy, no eggs, all flavor.

The rhubarb is non-negotiable—look for vibrant red stalks at the grocery store, avoiding any with leafy tops still attached. Trader Joe's and Whole Foods usually carry the freshest batches, but local farmers markets are your best bet for peak season flavor. For the vegan butter, Earth Balance or Miyoko's work perfectly, but keep it cold until ready to use—this is what makes the crust flaky. The cornstarch is a game-changer for the filling; don't substitute with flour or arrowroot, trust me on this. And that Grade B maple syrup? It's sweeter and richer than Grade A, giving your pie that restaurant-quality depth without overpowering the tart rhubarb.

No flaxseed? Chia seeds work at the same ratio, but flax gives the filling that perfect set. Running short on vegan butter? Coconut oil in the crust works, but the flavor won't be identical. The coconut milk for the whipped topping can be swapped for cashew cream if you're avoiding coconut, though it won't be quite as light. For the crust, King Arthur flour is my go-to—it's got that perfect protein balance for flakiness. And if you're worried about the crust being too rich, the tart rhubarb filling balances it perfectly. Pro tip: Let your rhubarb sit in the maple syrup mixture for 15 minutes before baking—it really lets the flavors meld.

The rhubarb filling keeps 3 days in the fridge once baked, though it's best eaten within 24 hours for maximum tartness. The crust stays fresh for 4 days if stored in an airtight container, but I always make a double batch—one for pie, one for hand pies. For the whipped coconut cream, whip it right before serving; it deflates fast. Freeze the pie (without the topping) for up to 3 months—just thaw at room temperature before adding the coconut cream. And if you're making this ahead for a party, assemble it completely, refrigerate overnight, then bake—it actually tastes better the next day.

Step-by-step instructions for vegan rhubarb pie

This pie delivers that perfect tart-sweet balance—all without dairy or butter substitutes!

First, mix the 1 tablespoon ground flaxseed with 3 tablespoons water in a small bowl. Stir well and let it sit for 10 minutes—it'll thicken into a gel-like consistency that mimics eggs perfectly. This is your vegan binder for the crust.

In a large bowl, combine the 2.5 cups all-purpose flour, 0.5 cup granulated sugar, 0.5 teaspoon salt, and 1.5 teaspoons ground cinnamon. Cut in the 1 cup cold vegan butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs. Sprinkle in the flax "egg" and 0.25 cup ice water, then gently toss with a fork until the dough just comes together.

Turn the dough onto a lightly floured surface and pat it into a 12-inch circle. Transfer to a parchment-lined pie dish and press gently into the bottom and up the sides. Trim any excess dough, leaving a ½-inch overhang. Chill in the refrigerator for 30 minutes while you prepare the filling.

Preheat your oven to 375°F. Line the chilled crust with a sheet of parchment paper, fill it with pie weights or dried beans, and bake for 15 minutes. Remove the weights and bake for another 5 minutes until the edges are lightly golden. This pre-baking prevents a soggy bottom when the juicy rhubarb filling goes in.

In a large saucepan, combine the 5 cups chopped fresh rhubarb, 0.75 cup maple syrup, and 1 tablespoon lemon juice. Bring to a gentle boil over medium-high heat, then reduce to medium-low and simmer for 10 minutes until the rhubarb softens but still holds its shape.

In a small bowl, whisk together the 0.25 cup cornstarch with 2 tablespoons cold water to make a slurry. Slowly pour this into the simmering rhubarb while stirring constantly. Cook for another 2-3 minutes until the filling thickens to a pudding-like consistency. Remove from heat and stir in the 1 teaspoon vanilla extract. Let it cool for 10 minutes before filling the crust.

Pour the cooled rhubarb filling into the pre-baked crust. Use a spatula to smooth the top, then dot with small pieces of the remaining vegan butter if desired. Bake at 375°F for 40-45 minutes, until the filling is bubbly and the crust is golden brown. If the edges brown too quickly, cover them with foil.

Let the pie cool completely on a wire rack for at least 2 hours—this is crucial for the filling to set properly. The contrast between the tart rhubarb and the sweet, spiced crust will be absolutely perfect.

While the pie cools, prepare the coconut whipped cream topping. Open the 1 can full-fat coconut milk and scoop out the thick cream that's collected at the top (leave the watery part behind). In a chilled bowl, whip the cream with an electric mixer until it forms soft peaks. Gradually add the 0.5 cup powdered sugar, 1 teaspoon vanilla extract, and a pinch of salt, continuing to whip until light and fluffy.

Serve the pie warm or at room temperature, topped with the coconut whipped cream. The bright acidity of the rhubarb pairs beautifully with the creamy, slightly sweet topping—pure comfort in every bite!

Storing and reheating your rhubarb pie recipe vegan

Refrigerator Storage

Store your vegan rhubarb pie in an airtight container at 40°F or below for up to 3 days. The crust stays crisp, while the rhubarb filling maintains its tart-sweet balance.

I always let the pie cool completely before storing to prevent condensation. Use a glass pie dish with a tight lid—it preserves the texture better than plastic. 🌟

Freezer Prep Tips

For longer storage, freeze the pie (without the coconut topping) for up to 3 months. Wrap it tightly in plastic wrap, then place in a freezer bag to prevent freezer burn.

Thaw overnight in the fridge before adding the whipped coconut cream. I’ve found that freezing the pie after it’s fully cooled prevents ice crystals from forming in the filling. 🧊

Reheating Warm Slices

For the best texture, reheat individual slices in a 350°F oven for 5-7 minutes or until warmed through. Microwaving works in a pinch—cover with a damp paper towel and heat for 20-30 seconds.

The crust stays flaky, and the rhubarb filling reheats beautifully. Avoid reheating the coconut topping—whip it fresh for the best texture. ⏰

Reviving Stale Crust

If the crust loses its crispness, brush the top with melted vegan butter and reheat at 375°F for 5 minutes. This restores the flaky texture without overcooking the filling. For extra crunch, sprinkle powdered sugar on the crust before reheating—it adds a caramelized finish. 💫

Coconut Topping Refresh

Never reheat the coconut whipped cream—it deflates and loses its lightness. Instead, whip a fresh batch using cold coconut cream and powdered sugar. Store the dry ingredients (powdered sugar, vanilla) separately in the fridge for up to 1 week, then whip with fresh coconut cream when ready.

This keeps the topping light and fluffy every time. 🥥
