Why you’ll love this recipe
Rhubarb brings a tart backbone, strawberries add brightness and natural sweetness, and the crumble topping is where texture happens—flaky, crunchy, and buttery with just enough oat chew. It’s forgiving if your fruit is a little juicy or you tweak the sugar to taste. You can serve it warm with vanilla ice cream or enjoy it at room temperature with a dollop of whipped cream. Little victories, right?

- Pinch of salt
For the crumble topping:

How to Make Strawberry Rhubarb Crumble
Time needed: 1 hour
Get your oven preheated and your favorite baking dish ready—this crumble comes together quickly.
- Preheat and prepare
Preheat your oven to 375°F (190°C). Lightly butter an 8×8-inch baking dish or similar pan.
- Make the filling
In a large bowl, combine the sliced rhubarb and halved strawberries. Sprinkle the sugar and cornstarch over the fruit, add lemon juice, vanilla, and a pinch of salt. Toss gently until everything is evenly coated. Let it sit for 5–10 minutes while you make the topping—this helps the fruit release a little juice and the cornstarch to start working.
- Make the crumble topping
In another bowl, stir together the oats, flour, brown sugar, cinnamon, and salt. Add the cold cubed butter and use a pastry cutter, two forks, or your fingertips to work the butter into the dry ingredients until the mixture resembles coarse crumbs with some pea-sized bits. Stir in the nuts if using.
- Assemble and bake
Pour the fruit into the prepared baking dish and spread it into an even layer. Sprinkle the crumble topping evenly over the fruit, pressing down gently in places so it makes good contact. Bake for 35–40 minutes, until the topping is golden and the filling is bubbling at the edges. If the topping browns too quickly, tent the dish loosely with foil for the last 10 minutes.
- Rest and serve
Let the crumble rest for 10–15 minutes before serving so the filling sets a bit—this makes it easier to spoon and keeps the texture lovely. Serve warm with a scoop of vanilla ice cream or a generous spoonful of whipped cream.
Tips & Tricks
- If your strawberries are exceptionally sweet, reduce the granulated sugar to 1/2 cup. Rhubarb is tart, so most cooks prefer a balance leaning a touch sweet.
- For a gluten-free version, swap the flour for a 1:1 gluten-free baking flour and use certified gluten-free oats.
- Cold butter is the secret to a flaky topping—don’t melt it.
- If you like a saucier crumble, stir an extra tablespoon of water into the filling before baking or add 1–2 tablespoons of orange juice for a citrus lift.
- Try pairing a small slice of the crumble with Coffee Pancakes for a brunch spread that feels indulgent but relaxed.
FAQs
Yes. Use frozen strawberries and rhubarb without thawing; add an extra tablespoon of cornstarch to help absorb the extra liquid and increase baking time by 5–10 minutes.
Let the baked crumble rest for at least 10 minutes before serving so the juices thicken. Also, don’t overfill the dish; a roomy oven-safe dish that allows even heat circulation helps the bottom set.
Absolutely. Assemble the crumble in the dish, cover, and refrigerate for up to 24 hours before baking. Alternatively, bake fully and reheat at 350°F (175°C) for 10–15 minutes until warmed through.
Conclusion
This strawberry rhubarb crumble is one of those desserts that feels special but is shockingly easy—perfect for lazy weekends, weeknight treats, or when you need a simple dessert for guests. Adjust the sugar to your fruit’s sweetness, keep the butter cold for the best topping, and don’t skip the resting time. When it comes out of the oven bubbling and golden, you’ll know you did something right.
Serve it warm with ice cream, and enjoy the tiny selfish moment of scraping the bottom of the dish—that’s the real prize. For a richer, nod-to-candy variation on dessert, the Samoa Cheesecake brings chocolate, caramel, and coconut into the party.
