Old Fashioned Strawberry Rhubarb Crisp
This easy Strawberry Rhubarb Crisp is the ultimate old fashioned dessert, bursting with jammy fruit and topped with a golden, buttery oat crumble. Simple to make and impossible to resist!
The Strawberry Rhubarb Crisp That Tastes Like a Summer Memory
If you have ever stood over a warm pan of bubbling fruit, breathing in that sweet-tart perfume while a golden oat topping crackles and crisps, you already know what this dessert is all about. This Old Fashioned Strawberry Rhubarb Crisp is everything a great summer dessert should be: simple to pull together, deeply comforting, and completely irresistible alongside a scoop of vanilla ice cream.
Strawberry rhubarb is one of those legendary flavor pairings that has stood the test of time, and for good reason. The rhubarb brings a bold tartness that cuts right through the sweetness of the strawberries, and together they create a jammy, jewel-toned filling that tastes like pure summer. This is the kind of recipe that becomes a household staple after you make it once.
Why a Crisp Beats a Pie Every Single Time
Here is the honest truth: a classic strawberry rhubarb crisp easy enough for a weeknight and impressive enough for a dinner party. There is no chilling pastry dough, no blind baking, no fussing over a lattice top. You toss the fruit, mix the topping, layer it all together, and let the oven do its magic.
The result? A strawberry rhubarb crisp dessert with a filling that bubbles up like a good jam and a topping that shatters with every spoonful. The contrast between that tender, syrupy fruit and the crunchy oat crumble is what makes people go back for a second serving.
Chef's Tip: Cold butter is the secret to a truly crunchy crisp topping. If your kitchen is warm, pop the cubed butter back into the freezer for 10 minutes before working it into the oat mixture. Small, pea-sized chunks of butter in the topping are exactly what you want.
Choosing Your Fruit: Fresh vs. Frozen
Fresh rhubarb and strawberries at peak ripeness will give you the best flavor in this strawberry rhubarb crisp recipe, but frozen fruit is a completely valid and delicious option when fresh is out of season. If you go the frozen route, do not thaw it first. Just toss it straight from the freezer with the sugar and cornstarch and let the oven work it all out.
For fresh fruit, look for rhubarb stalks that are firm and deeply pink or red, and strawberries that smell fragrant and sweet at the stem. The better your fruit, the better your filling.
Before we dive in, having the right tools on hand makes assembling this recipe a breeze. A sturdy pastry cutter is the fastest way to work cold butter into the topping, and a good 9x13-inch baking dish ensures your filling cooks evenly from edge to edge.
Building the Perfect Oat Crisp Topping
This is where the best strawberry rhubarb crisp lives or dies. A few non-negotiable rules:
- Use old fashioned rolled oats, not instant oats. Instant oats turn mushy in the oven. Rolled oats hold their shape and give you that signature crunch.
- Pack your brown sugar for a rich, caramel-like sweetness that deepens as it bakes.
- Keep the butter cold. Say it again: cold butter. It creates steam pockets as it melts, which puffs up the topping and gives it texture.
- Work quickly with your hands. The goal is a crumbly, slightly clumpy mixture, not a smooth paste.
Warning: Resist the urge to press the topping down flat over the fruit. A loose, uneven crumble bakes up crunchier and lets the fruit filling bubble up beautifully through the gaps.

Old Fashioned Strawberry Rhubarb Crisp
This easy Strawberry Rhubarb Crisp is the ultimate old fashioned dessert, bursting with jammy fruit and topped with a golden, buttery oat crumble. Simple to make and impossible to resist!
Ingredients
- 3 cups fresh strawberries, hulled and halved
- 3 cups fresh rhubarb, cut into 0.5-inch pieces
- 1/2 cup granulated sugar, for the fruit filling
- 2 tbsp cornstarch
- 1 tbsp lemon juice, freshly squeezed
- 1 tsp vanilla extract, pure, not imitation
- 1 cup old fashioned rolled oats, not instant
- 3/4 cup all-purpose flour
- 3/4 cup packed brown sugar, light or dark both work
- 1/2 tsp ground cinnamon
- 1/4 tsp salt
- 1/2 cup unsalted butter, cold, cut into small cubes
Instruction
Preheat your oven to 350 degrees F (175 degrees C) and lightly grease a 9x13-inch baking dish with butter or nonstick spray.
In a large bowl, combine the strawberries, rhubarb, granulated sugar, cornstarch, lemon juice, and vanilla extract. Toss well until everything is evenly coated. Pour the fruit mixture into the prepared baking dish and spread it into an even layer.
In a separate medium bowl, stir together the rolled oats, flour, brown sugar, cinnamon, and salt until combined.
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, covering it from edge to edge.
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 rest for at least 10 minutes before serving. This allows the filling to thicken up slightly. Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream.
Equipment
- 9x13-inch baking dish
- Large mixing bowl
- Medium mixing bowl
- Pastry cutter or your fingertips
- Cutting board and sharp knife
- Measuring cups and spoons
- Citrus juicer
Notes
Serving, Storing, and Making It Your Own
Serve this rhubarb strawberry crisp warm, straight from the baking dish. A generous scoop of good vanilla ice cream melting into the hot fruit is the classic move, and honestly, there is no improving on it. Lightly sweetened whipped cream or a spoonful of creme fraiche are equally wonderful if you want something a little more restrained.
Variations worth trying:
- Add a pinch of cardamom or ground ginger to the fruit filling for a subtle warmth.
- Stir a handful of chopped pecans or sliced almonds into the crisp topping for extra crunch.
- Swap half the strawberries for fresh blueberries or raspberries for a mixed berry and rhubarb version.
This crisp keeps well, covered, in the refrigerator for up to 4 days. The topping softens slightly overnight, but a quick blast in a warm oven brings it right back. Whether you are making it for a backyard barbecue, a potluck, or just because the rhubarb at the farmers market looked too good to pass up, this old fashioned strawberry rhubarb crisp will not let you down.
