Classic Strawberry Rhubarb Crisp Recipe
Tart rhubarb and sweet strawberries under a buttery oat crumble
By Sarah Mitchell • June 14, 2026
Rhubarb crisp is dominating Pinterest with a 500% monthly growth — and for good reason. This quintessential spring dessert perfectly balances the tart bite of rhubarb with the natural sweetness of fresh strawberries, all topped with the most buttery, crumbly oat topping you've ever tasted.
The filling comes together in minutes: chopped rhubarb and strawberries tossed with sugar, a touch of cornstarch, and a squeeze of lemon. As it bakes, the fruit softens into a bubbling, jammy filling that's absolutely irresistible.
The oat crumble topping is where the magic happens — cold butter, brown sugar, oats, and a pinch of cinnamon create golden, crunchy clusters that shatter with every bite. Serve warm with a scoop of vanilla ice cream and you've got a dessert that tastes like the best of summer.
