Rhubarb Tart with Oat Crust Ingredients
For the Oat Crust
• Quick Oats – Adds a subtle oat flavor to the crust; can substitute with oat flour, adding an extra tablespoon of water for texture.
• All-Purpose Flour – Provides structure to the pastry; remember to reserve some extra flour for rolling out.
• Sugar – Sweetens both the crust and the rhubarb filling; light brown sugar can be used for a richer taste.
• Kosher Salt – Balances the flavors in the crust, enhancing the overall taste.
• Cold Butter – Creates the ideal flaky texture for the crust; keep it very cold right up until use.
• Ice Water – Binds the crust ingredients; for best results, ensure it’s ice-cold.
For the Rhubarb Filling
• Diced Rhubarb – The star ingredient, fresh rhubarb gives a delightful tartness; if unavailable, frozen rhubarb can work in a pinch.
• Cornstarch – Thickens the filling to keep it from becoming soggy; vital for achieving the right consistency.
• Lemon Juice – Brightens the flavor of the filling and adds a touch of acidity to balance sweetness.
For Topping
• Beaten Egg – Brush over the crust for a beautiful golden color when baked.
• Turbinado Sugar – Sprinkled on top adds a delightful crunch and sweet contrast; granulated sugar is an alternative but less crunchy.
• Whipping Cream – A luxurious side for serving; can substitute with dairy-free cream for a vegan option.
Step‑by‑Step Instructions for Rustic Rhubarb Tart with Oat Crust
Step 1: Prepare Dough
In a food processor, blend the quick oats until finely ground. Add the all-purpose flour, sugar, and kosher salt, pulsing to combine. Cut in the cold butter until the mixture resembles coarse crumbs, about pea-sized pieces. Gradually add ice water, mixing just until the dough starts to clump together.
Step 2: Chill Dough
Gather the dough into a ball and wrap it tightly in cling film. Chill in the refrigerator for 30 to 60 minutes, allowing it to firm up. This chilling step is crucial for achieving that flakiness in the crust, ensuring it bakes beautifully in your Rustic Rhubarb Tart with Oat Crust.
Step 3: Preheat Oven
While the dough chills, preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper to catch any drips from the tart. This preparation ensures that your crust bakes evenly, achieving the perfect golden-brown color that complements the tangy rhubarb filling.
Step 4: Roll Dough
Once chilled, dust a clean surface with flour and roll out the dough into a 12-inch circle, keeping it about 1/8-inch thick. If cracks form, simply mend them with your fingers. Carefully transfer the rolled dough onto the prepared baking sheet, ready to be filled with that irresistible rhubarb mixture.
Step 5: Prepare Filling
In a large mixing bowl, toss the diced rhubarb with sugar, cornstarch, and lemon juice until everything is evenly coated. The sugar will help to draw out the natural juices from the rhubarb, while the cornstarch thickens the filling, preventing a soggy tart once it bakes.
Step 6: Assemble Tart
Spoon the rhubarb mixture into the center of the rolled dough, leaving a 1.5-inch border around the edges. Fold the crust edges over the filling, creating a rustic look. Brush the exposed dough with the beaten egg to achieve a beautiful golden finish, and sprinkle the turbinado sugar on top for added sweetness and crunch.
Step 7: Bake
Place the tart in the preheated oven and bake for 40 to 50 minutes, or until the crust is golden and the filling is bubbling. Keep an eye on it, as you want that inviting golden hue while the tart fills your kitchen with a delightful aroma.
Step 8: Whip Cream
While the tart cools for 20 to 30 minutes, prepare your whipped cream. In a mixing bowl, beat the cream until soft peaks form, then add sugar and continue whipping until stiff peaks are achieved. Serve this luscious cream atop each slice of your Rustic Rhubarb Tart with Oat Crust for that extra touch of indulgence.

Rhubarb Tart with Oat Crust Recipe FAQs
How do I select ripe rhubarb?
Absolutely! When choosing rhubarb, look for firm stalks that are vibrant in color—preferably a mix of green and pink hues. Avoid stalks with dark spots or wilting, as these may indicate age or spoilage.
How should I store leftover rhubarb tart?
Once you’ve enjoyed your delicious rhubarb tart, store any leftovers in the refrigerator, where it will keep fresh for up to 3 days. Be sure to cover it tightly with plastic wrap or aluminum foil to maintain moisture and flavor.
Can I freeze the rhubarb tart?
Certainly! To freeze your rhubarb tart with oat crust, slice it first, then wrap each slice tightly in plastic wrap and place them in an airtight container. It can be frozen for up to 2 months. When you’re ready to enjoy, simply reheat it in a 350°F (175°C) oven for about 10-15 minutes or until warmed through.
What should I do if my tart filling is too runny?
If you find your filling is a bit too runny after baking, don’t worry! This can happen if the rhubarb has released too much moisture. A great way to tackle this is to add an extra tablespoon of cornstarch mixed with sugar in the filling. Always remember to allow the tart to cool completely before slicing, as this will help thicken the filling as well.
Are there any dietary considerations for this rhubarb tart?
The rhubarb tart with oat crust is generally vegetarian-friendly. However, if you’re making it for someone with allergies, be mindful that it contains gluten from the all-purpose flour and possible dairy from the butter and whipped cream.
