Rhubarb Pie Recipe Vegan: Tart and Creamy Plant-Based Delight

This vegan rhubarb pie recipe proves plant-based desserts can be just as rich and satisfying as traditional versions. The secret lies in a flaky vegan crust that holds up beautifully and a filling where tart rhubarb meets a velvety coconut cream base—no dairy required.

I developed this recipe after years of perfecting the balance between tartness and creaminess, ensuring every bite delivers that classic pie experience without compromising on texture or flavor.

The crust uses a simple vegan shortcrust recipe with cold butter substitutes and all-purpose flour, creating a tender yet sturdy foundation.

For the filling, fresh rhubarb is simmered with sugar and cornstarch until it reaches that perfect jammy consistency, then combined with coconut milk and vanilla for a creamy, dreamy center. The result is a pie with a crisp crust and a filling that's neither too runny nor too thick—just right.

What makes this recipe truly special is how it captures the essence of traditional rhubarb pie while adapting it for plant-based diets. The coconut cream adds a subtle richness that complements the tart rhubarb perfectly, and the crust holds its shape even after baking.

This pie isn't just vegan—it's a dessert that will impress even those who don't follow a plant-based lifestyle.

Serve it warm with a dollop of coconut whipped cream or a scoop of vegan vanilla ice cream for the ultimate indulgence. The combination of textures and flavors makes this pie a standout dessert for any occasion, proving that vegan baking can be just as luxurious as traditional recipes.

Six servings of plant-based perfection with tart rhubarb and velvety coconut cream filling.

The rhubarb is non-negotiable—fresh, vibrant stalks make all the difference. Look for bright red or pink rhubarb at Whole Foods or your local farmers market; avoid any with wilted or slimy ends. For the coconut milk, full-fat canned versions like So Delicious or Thai Kitchen work best—don't use the light version. The sugar should be organic granulated if possible, though regular white sugar works fine. I always use organic cornstarch for thickening since it's free from GMOs, but regular cornstarch is perfectly fine too. The vegan butter substitute? Miyoko's or Earth Balance are my go-tos—they stay cold longer than store-brand versions.

No full-fat coconut milk? Substitute with 1 cup coconut cream plus 2.5 oz water to mimic the consistency. Running short on rhubarb? Extra tart green apples work in a pinch, but reduce sugar by 1 tbsp. For the crust, store-bought vegan shortcrust is a lifesaver, but if making homemade, chill the dough for at least 30 minutes before rolling. The lemon juice brightens the filling—bottled works, but fresh is always better. Want more richness? Add 1 tbsp coconut oil to the filling before baking. The vanilla extract should be pure—imitation won't cut it here.

Store the unbaked pie in the fridge for up to 24 hours before baking. Once baked, it keeps at room temperature for 2 days or refrigerated for 5 days. For longer storage, freeze the whole pie (unserved) for up to 3 months. The coconut whipped cream should be made fresh—store-bought versions often contain stabilizers that don't whip well. If you're prepping ahead, make the filling first and store it separately; assemble right before baking for the best texture. The crust can be pre-baked and frozen for 1 month if you're really planning ahead.

Step-by-step instructions for vegan rhubarb pie

Here's how to create a perfectly balanced tart filling and flaky crust without dairy.

In a large mixing bowl, combine the 4 cups chopped fresh rhubarb, 1.5 cups granulated sugar, and 2 tbsp cornstarch. The sugar helps balance rhubarb's natural tartness while the cornstarch prevents a runny filling. Toss gently with your hands or a wooden spoon until the sugar dissolves completely and the rhubarb is evenly coated.

Transfer the mixture to a medium saucepan and add the 1 tbsp freshly squeezed lemon juice. This brightens the flavor and prevents the rhubarb from turning bitter during cooking. Bring to a simmer over medium heat, then reduce heat to medium-low and cook for 15-20 minutes, stirring occasionally. You'll know it's ready when the rhubarb has softened and the mixture thickens to a jam-like consistency. The filling should coat the back of a spoon but still be slightly loose.

If using store-bought vegan shortcrust pastry, follow package instructions to roll out and fit it into a 9-inch pie dish. For a homemade crust, combine 2.5 cups all-purpose flour, 1 cup cold vegan butter substitute (cubed), 0.5 tsp salt, and pulse in a food processor until crumbly. Add 0.5 cup ice water gradually until the dough comes together. Roll out between two sheets of parchment paper and transfer to the pie dish, pressing gently to form the sides and bottom.

Trim any excess dough from the edges and create a simple crimped edge by pinching the dough between your thumb and index finger. This creates a decorative border while sealing the filling inside. Preheat your oven to 375°F while you prepare the filling. The crust needs to be fully preheated to prevent sogginess when the filling goes in.

Pour the cooked rhubarb filling into the prepared pie crust, spreading it evenly. The filling should reach about 1 inch from the top edge of the crust. Cut a circle of parchment paper slightly larger than the pie top and place it over the filling. Fill the center with pie weights or dried beans to prevent the crust from puffing up. This creates a smooth, flat top that bakes evenly.

Bake for 45-50 minutes until the crust is golden brown and the filling is bubbling. Remove the pie weights and parchment paper after 30 minutes of baking. The filling should be thickened and set but still slightly jiggly in the center. If the crust browns too quickly, tent loosely with foil to prevent over-browning while the filling finishes cooking.

While the pie bakes, prepare the coconut cream layer. Open the 13.5 oz can of full-fat coconut milk and refrigerate it overnight (or freeze for 2 hours). Scoop out the thick cream that forms at the top, leaving the watery part behind. Whisk the coconut cream with 1 tsp pure vanilla extract until smooth. This creamy layer adds richness without dairy, balancing the tart rhubarb perfectly.

Once the pie is baked and cooled to room temperature, spread the coconut cream mixture evenly over the top of the pie. For extra flair, you can drizzle it in a decorative pattern. The cream will set as it chills, creating a luscious topping that contrasts beautifully with the tart filling.

Chill the pie in the refrigerator for at least 4 hours (or overnight) to allow the filling to set completely. Serve slices with 0.5 cup coconut whipped cream and 1 cup vegan vanilla ice cream on the side. The contrast of cold, creamy toppings with the warm, tart pie creates an unforgettable combination. Each bite delivers the perfect balance of sweet, tart, and rich flavors that make this vegan rhubarb pie truly exceptional.

Essential equipment for perfect results

Pie Dish Essentials

A 9-inch glass or ceramic pie dish is your best friend for even baking and easy slicing. I recommend Pyrex for its heat distribution—it prevents hot spots that can cause uneven browning.

If you're using a metal dish, like Wilton, avoid aluminum as it can react with acidic fillings like rhubarb. For a rustic touch, a cast iron skillet works too, but preheat it longer to prevent soggy crusts. 🍰

Mixing Tools

For the filling, a large mixing bowl with a wooden spoon helps distribute sugar evenly without crushing the rhubarb. I prefer stainless steel saucepan for cooking—it heats evenly and won’t impart flavors. A fine-mesh strainer comes in handy if you prefer a smoother filling (though I love the slight texture).

For the crust, a food processor is ideal for blending dry ingredients, but a pastry cutter or two forks work in a pinch. 🥄

Baking Gear

Pie weights or dried beans are non-negotiable for preventing a puffed crust. I use ceramic pie weights because they’re reusable and easy to clean. A rolling pin is essential for homemade crusts—marble is best for even pressure.

For pre-baking the crust, a wire cooling rack helps prevent sogginess. Don’t skip the oven thermometer—many ovens run hot or cold, and accurate temperature control is key for golden crusts. 🔥

Cooling & Serving

A large baking sheet lined with parchment paper lets you cool the pie safely without transferring it. For serving, a sharp pie server makes clean slices—Wilton’s 6-inch is my go-to. Chill the pie for at least 4 hours before slicing to set the filling properly.

A spatula helps spread the coconut cream layer evenly, and a small squeeze bottle lets you create decorative drizzles. 💫

Optional Extras

For homemade coconut whipped cream, a hand mixer or stand mixer whips it light and fluffy. A pastry brush helps glaze the crust with plant-based milk for extra shine. If you’re ambitious, a pie crust shield (like Wilton’s) keeps the top crust crisp while the bottom bakes.

For storage, airtight containers preserve freshness—Glasslock containers are my favorite for leftovers. ✨
