This Easy Strawberry Rhubarb Crisp is the perfect simple summer dessert, with a juicy, sweet-tart fruit filling and a golden, buttery oat topping that bakes up perfectly every time.

If there is one dessert that truly captures the spirit of early summer, it is a bubbling, golden strawberry rhubarb crisp. Sweet, jammy strawberries and bracingly tart rhubarb come together under a buttery, crunchy oat topping that is somehow both rustic and completely irresistible. This is the kind of dessert that fills your kitchen with the most incredible smell and disappears from the pan within minutes of hitting the table.
Unlike a more finicky strawberry rhubarb pie with its crimped crust and blind-baking, this simple strawberry rhubarb crisp is genuinely weeknight-friendly. You do not need a stand mixer, a rolling pin, or any special skills. Just two bowls, a baking dish, and about 15 minutes of hands-on prep. The oven does the rest.
Using quality ingredients and the right baking dish makes a noticeable difference in how evenly your crisp bakes and how beautifully the topping crisps up. A good pastry cutter also takes the effort out of working cold butter into the topping.
Rhubarb on its own is aggressively sour, almost unpleasant eaten raw. But pair it with ripe, sweet strawberries in roughly equal amounts and something magical happens. The two balance each other perfectly, the strawberries softening the rhubarb's sharp edge while the rhubarb keeps the filling from becoming cloying. It is the classic strawberry rhubarb combo for a reason.
A small squeeze of lemon juice and a splash of vanilla in the filling amplifies both fruits, and the cornstarch thickens the juices as everything bakes into a glossy, spoonable filling that stays together beautifully.
Chef's Tip: Do not skip the resting time after baking. Letting the crisp cool for at least 15 minutes allows the filling to thicken up and set, so you get clean, scoopable portions instead of a soupy mess. It is worth the wait, we promise.
The topping is where a crisp lives or dies. This one uses old-fashioned rolled oats (never instant), all-purpose flour, brown sugar, cinnamon, salt, and cold butter. The cold butter is the key. Working it in with your fingertips until the mixture forms rough, uneven clumps means you get pockets of buttery richness that toast up into something deeply crunchy and golden.
For a gluten-free strawberry rhubarb crisp, simply swap the flour for a certified 1-to-1 gluten-free baking blend and use certified gluten-free oats. The texture is virtually identical and just as satisfying.
A few topping tips:
This crisp is wonderful warm, but it is transcendent with a generous scoop of vanilla ice cream melting over the top. The contrast of hot fruit and cold cream is genuinely one of the great pleasures of summer baking. A cloud of lightly sweetened whipped cream is a close second.
For a slightly more elegant presentation, try serving individual squares in shallow bowls, similar to a strawberry rhubarb crisp square or plated dessert, dusted lightly with powdered sugar.

This Easy Strawberry Rhubarb Crisp is the perfect simple summer dessert, with a juicy, sweet-tart fruit filling and a golden, buttery oat topping that bakes up perfectly every time.
Preheat your oven to 350 degrees F (175 degrees C). Lightly grease a 9x13-inch or similar 2-quart baking dish.
In a large bowl, combine the halved strawberries and chopped rhubarb. Add the granulated sugar, cornstarch, lemon juice, and vanilla extract. Toss everything together until the fruit is evenly coated, then spread it out in an even layer in the prepared baking dish.
In a separate medium bowl, combine the rolled oats, flour, brown sugar, cinnamon, and salt. Whisk together to combine.
Add the cold, cubed butter to the oat mixture. Using your fingertips or a pastry cutter, work the butter into the dry ingredients until the mixture resembles coarse, clumpy crumbs with some pea-sized pieces of butter remaining. Do not overwork it.
Sprinkle the crisp topping evenly over the fruit filling in the baking dish, covering it completely.
Bake for 40 to 45 minutes, until the topping is deep golden brown and the fruit filling is bubbling up around the edges.
Remove from the oven and let the crisp cool for at least 15 minutes before serving. This allows the filling to set slightly. Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream.
One of the best things about this simple strawberry rhubarb crisp is how well it stores. Leftovers keep in the refrigerator for up to 5 days and reheat beautifully. If you want to prep ahead, assemble the whole dish, cover it, and refrigerate it unbaked for up to 24 hours. It goes straight from the fridge to the oven, making it a brilliant make-ahead option for dinner parties or holidays.
However you serve it, this is the kind of dessert people ask for the recipe for every single time.
