How to Make Rhubarb Tart with Oat Crust
-
Prepare the Dough: Begin by blending quick oats in a food processor until they’re fine. Combine the oats with all-purpose flour, sugar, and kosher salt. Cut in the cold butter until the mixture resembles pea-sized crumbs. Gradually add ice water, pulsing until the dough forms, then chill for 30-60 minutes.
-
Preheat the Oven: Set your oven to 400°F (200°C) and line a baking sheet with parchment paper to prevent sticking and for easy cleanup.
-
Roll Out the Dough: After chilling, roll the dough into a 12-inch circle on a lightly floured surface. Carefully transfer the rolled dough to your prepared baking sheet, making sure it stays intact.
-
Prepare the Filling: In a bowl, toss the diced rhubarb with sugar, cornstarch, and lemon juice. This mixture will create a balance of sweetness with a delightful tart kick.
-
Assemble the Tart: Spoon the rhubarb filling into the center of the pastry, leaving about a 1.5-inch border around the edges. Fold the crust over the filling, pleating it as you go. Brush the edges with the beaten egg and sprinkle with turbinado sugar for added texture.
-
Bake: Slide the tart into your preheated oven and bake for 40-50 minutes. You’re looking for a golden-brown crust and bubbling filling. Once done, cool for 20-30 minutes before slicing, allowing all those flavors to meld beautifully.
-
Whip the Cream: While the tart cools, beat the whipping cream until soft peaks form. Add additional sugar to taste, then whip until stiff peaks form for a delightful topping.
Optional: Enjoy with a scoop of vanilla ice cream for an indulgent treat.

Rhubarb Tart with Oat Crust Recipe FAQs
What should I look for when selecting rhubarb?
Absolutely! When choosing fresh rhubarb, look for firm stalks that are vibrant in color—preferably a deep ruby red. Avoid any that are wilted or have dark spots all over, as these are signs of age. If fresh rhubarb isn’t available, frozen rhubarb is a perfectly fine substitute; just ensure it’s well-thawed and drained before using!
How should I store leftover rhubarb tart?
To keep your rhubarb tart fresh, store it in an airtight container in the refrigerator for up to 3 days. If you happen to have leftovers, they can be slightly less crisp, so reheating in the oven will bring some of that original texture back.
Can I freeze rhubarb tart?
Very! To freeze your rhubarb tart, first allow it to cool completely. Then wrap it tightly in plastic wrap followed by aluminum foil to prevent freezer burn. It will keep well for up to 1 month. When you’re ready to enjoy it again, thaw it in the fridge overnight, then reheat in a 350°F (175°C) oven for about 15-20 minutes.
What can I do if my tart filling is too runny?
If your rhubarb filling turns out runny after baking, it may need more cornstarch or a longer bake time next time. To fix it post-baking, consider baking it a bit longer on low heat to help evaporate excess moisture. A helpful tip for the future is to make sure to toss the rhubarb with sugar and cornstarch before adding it to the tart; this helps absorb some of that moisture!
Are there any dietary restrictions I should consider?
When making this rhubarb tart with oat crust, be mindful of allergies—especially with the use of butter and potential cross-contamination if you’re baking for someone with a gluten sensitivity. You can substitute the all-purpose flour with a gluten-free blend and use a vegan butter alternative to accommodate those with dietary restrictions.
Can pets eat rhubarb?
No, it’s important to note that rhubarb leaves are toxic to pets! Always ensure that when you’re preparing this dish, the rhubarb stalks are kept away from curious pets. If you’ve got a furry friend that likes to nibble, give them pet-safe fruits or veggies instead!
