Rhubarb Puff Pastry Tarts (Easy & Irresistible)
These flaky rhubarb puff pastry tarts are buttery, golden, and bursting with tart-sweet filling. Ready in under an hour, they are the easiest way to turn fresh rhubarb into a showstopping treat.
The Easiest Rhubarb Pastry You Will Ever Make
If you have ever stood in front of a pile of brilliant pink rhubarb stalks and wondered what to do with them, this recipe is your answer. These rhubarb puff pastry tarts are everything a great seasonal bake should be: fast, forgiving, and completely stunning on a plate. The filling is sticky-sweet with just enough tartness to keep things interesting, the cream cheese layer adds a quiet richness underneath, and the pastry puffs into golden, shatteringly crisp layers around the edges.
Think of these as a grown-up version of rhubarb pop tarts, or a more rustic take on a classic rhubarb tart with puff pastry. Either way, they come together in under an hour using a single sheet of store-bought puff pastry and a handful of pantry staples.
Why Puff Pastry Is the Right Choice for Rhubarb
Rhubarb is intensely tart and releases a good amount of liquid as it cooks. A shortcrust or butter pastry can turn soft and dense under that kind of moisture. Puff pastry, on the other hand, is built for this. The high heat causes all those buttery layers to steam and separate, lifting the border up into a dramatic golden frame while the base stays just firm enough to hold the filling without going soggy, especially with that cream cheese barrier doing its job underneath.
This is also one of the most versatile rhubarb pastry recipes you can keep in your back pocket. Once you know the base method, you can riff endlessly. Stir in a handful of strawberries for strawberry rhubarb puff pastry, swap the vanilla for a pinch of cardamom, or drizzle the finished tarts with honey instead of powdered sugar.
Using quality puff pastry makes a genuine difference here. A good all-butter puff pastry bakes up richer, flakier, and more golden than the shortening-based alternatives. It is worth seeking out.
How to Pick and Prep Your Rhubarb
For this recipe, you want stalks that are firm, vibrantly colored, and free of soft spots. Deeper pink or red stalks tend to look more dramatic once baked, though the color does not always predict flavor. Green rhubarb is equally tart and delicious.
A few things to keep in mind:
- Always remove the leaves. Rhubarb leaves are toxic and should never be used in cooking.
- Slice evenly. Uniform half-inch pieces cook at the same rate and sit neatly on the pastry.
- Let the filling macerate. Tossing the rhubarb with sugar and letting it sit for 10 minutes draws out some moisture and starts to soften the pieces slightly, which means they cook through beautifully in the short baking window.
Chef's Tip: If your rhubarb seems especially tart after tasting a small piece raw, bump the sugar up by a tablespoon or two. Rhubarb tartness varies wildly by variety and growing season, so your palate is the best guide.
The Cream Cheese Layer Is Not Optional (Kind Of)
I know it is tempting to skip steps, but the whipped cream cheese base here is genuinely doing two jobs at once. First, it creates a thin protective barrier between the wet rhubarb filling and the raw pastry, which is a big reason the bottoms stay crisp instead of turning into mush. Second, it adds a quiet, tangy creaminess that rounds out the sharp edges of the rhubarb in the most satisfying way.
If you love rhubarb cream puff style desserts, this layer will feel very familiar. It is not sweet or heavy. It just makes everything taste more intentional.

Rhubarb Puff Pastry Tarts (Easy & Irresistible)
These flaky rhubarb puff pastry tarts are buttery, golden, and bursting with tart-sweet filling. Ready in under an hour, they are the easiest way to turn fresh rhubarb into a showstopping treat.
Ingredients
- 1 puff pastry sheet, store-bought, thawed overnight in the fridge
- 3 fresh rhubarb stalks, trimmed and sliced into 0.5-inch pieces
- 3/8 cup granulated sugar, adjust to taste depending on rhubarb tartness
- 1 tbsp cornstarch
- 1/2 tsp vanilla extract, pure, not imitation
- 1 tsp lemon zest, from about half a lemon
- 1 tsp lemon juice, freshly squeezed
- 4 oz cream cheese, softened to room temperature
- 2 tbsp powdered sugar, for the cream cheese layer
- 1 large egg, beaten, for egg wash
- 1 tbsp coarse or turbinado sugar, for topping, optional but recommended
- 1/4 cup powdered sugar, for dusting finished tarts
Instruction
Preheat your oven to 400 degrees F (200 degrees C) and line a large baking sheet with parchment paper.
In a medium bowl, toss the sliced rhubarb with granulated sugar, cornstarch, lemon zest, lemon juice, and vanilla extract. Stir well and let it sit for 10 minutes so the rhubarb releases a bit of juice and the sugar dissolves.
In a small bowl, beat together the softened cream cheese and powdered sugar until smooth and creamy. Set aside.
Unfold the thawed puff pastry sheet on a lightly floured surface. Cut it into 6 equal rectangles.
Transfer the rectangles to the prepared baking sheet, spacing them about 1 inch apart.
Score a border about 0.5 inches from the edge of each rectangle using a sharp knife, pressing only halfway through the pastry so the edges can puff up around the filling.
Spread a thin layer of the cream cheese mixture in the center of each rectangle, staying inside the scored border.
Spoon the rhubarb mixture evenly over the cream cheese layer on each tart.
Brush the exposed pastry border on each tart lightly with the beaten egg wash.
Sprinkle the tops with coarse or turbinado sugar for a sparkling, caramelized finish.
Bake for 22 to 25 minutes, until the pastry is deeply golden and puffed and the rhubarb is tender and bubbling at the edges.
Let the tarts cool on the baking sheet for at least 10 minutes before dusting with powdered sugar and serving.
Equipment

Notes
Serving, Storing, and Making Ahead
These tarts are at their absolute best fresh from the oven, still warm, with a dusting of powdered sugar drifting down over all those puffed golden edges. Serve them as a dessert with a scoop of vanilla ice cream or a spoonful of lightly whipped cream. They also work beautifully as a brunch pastry alongside a strong cup of coffee.
For make-ahead prep: The cream cheese mixture and rhubarb filling can both be made up to 24 hours in advance and stored separately in the refrigerator. When you are ready to bake, simply assemble and pop them straight into the oven.
Leftovers keep in the fridge for up to 3 days. Reheat in a 350-degree oven for 8 to 10 minutes to bring the crispness back. Skip the microwave entirely.
A Few Variations Worth Trying
- Strawberry Rhubarb Puff Pastry: Replace half the rhubarb with sliced fresh strawberries and reduce the sugar slightly.
- Rhubarb and Ginger: Add half a teaspoon of freshly grated ginger to the filling for a warming, spicy kick.
- Almond Rhubarb Tart: Swap the cream cheese layer for a thin spread of almond paste for a more bakery-style finish.
However you make them, one thing is certain: a single sheet of puff pastry and a few stalks of rhubarb can produce something genuinely beautiful. That is the kind of recipe worth keeping around.
