This strawberry rhubarb crisp recipe combines 3 cups of sliced rhubarb and 3 cups of strawberries with a buttery oat topping, then bakes in an 8-inch square dish at 375°F for 40–50 minutes. It takes about 15–20 minutes to prepare and makes 6–8 servings, making it an easy fruit dessert for a family dinner, spring gathering, or relaxed weekend treat.

This strawberry rhubarb crisp is the kind of dessert that feels special without requiring complicated pastry work. The fruit filling comes together in one bowl, and the topping only needs a quick mix before it is scattered over the top.
Rhubarb brings a lively tartness, while strawberries add floral sweetness and a beautiful red color. Cornstarch helps the fruit juices become spoonable as the crisp cools, and lemon juice keeps the flavor fresh rather than heavy.
The topping is equally appealing, with old-fashioned rolled oats for a pleasant chew, flour for structure, brown sugar for warm caramel notes, and cold butter for crisp, irregular crumbs. For another fruit-forward dessert idea, you can also try our easy blueberry crisp.
Ingredients You’ll Need
Start with firm, brightly colored rhubarb and strawberries that are ripe but not mushy. Cut the rhubarb into slices about 1/2 inch thick, and keep the strawberries in fairly large halves or quarters so they retain some shape while baking.
- Fruit: 3 cups sliced rhubarb and 3 cups hulled, halved or quartered strawberries.
- Sweet and bright flavors: 1/2 cup granulated sugar, 1 tablespoon fresh lemon juice, 1 teaspoon vanilla extract, and 1/8 teaspoon salt.
- Thickener: 2 tablespoons cornstarch to help the bubbling fruit filling set as it rests.
- Topping: 1 cup old-fashioned rolled oats, 1/2 cup all-purpose flour, 1/2 cup packed light brown sugar, 1/2 teaspoon cinnamon, and 1/4 teaspoon salt.
- Butter: 6 tablespoons unsalted butter, cold and cut into small cubes.
Although the ingredient list is short, each item has a purpose. Old-fashioned oats provide a better chew than quick oats, and cold butter keeps the topping crumbly instead of dense.

How to Make It Step-by-Step
Step 1: Heat the oven to 375°F. Lightly butter an 8-inch square baking dish, making sure the butter reaches the corners and sides so the finished servings release easily.
Step 2: Add the sliced rhubarb and strawberries to a mixing bowl. Sprinkle in the granulated sugar, cornstarch, lemon juice, vanilla extract, and salt, then stir gently until every piece of fruit is coated without crushing the strawberries.
Step 3: Pour the fruit mixture into the prepared baking dish. Spread it evenly so the fruit bakes at the same rate and the topping has a level surface.
Step 4: In a clean bowl, combine the rolled oats, all-purpose flour, light brown sugar, cinnamon, and salt. Break up any packed brown sugar before adding the butter so the topping mixes evenly.
Step 5: Add the cold butter cubes and cut them into the oat mixture with a pastry cutter. You can also rub the butter in with your fingertips, stopping when coarse crumbs form and some small butter pieces remain visible.
Step 6: Scatter the topping over the fruit in an even layer. Do not press it down, because a loose topping allows heat to circulate and creates a lighter, more textured crust.
Step 7: Bake for 40–50 minutes, watching for bubbling juices around the edges and a golden-brown topping. If the fruit is bubbling but the topping needs a little more color, continue baking until both signs are present.
Step 8: Remove the dish from the oven and let it cool for at least 15 minutes. This pause gives the cornstarch time to thicken the juices, so each serving is juicy without being overly runny.
Pro Tips for the Best Crisp
Cold butter is one of the most important details in this recipe. When small pieces of chilled butter remain in the topping, they melt in the oven and create crisp, uneven crumbs instead of a compact layer.
Keep the strawberry pieces fairly large. Very small pieces can soften completely during the 40–50 minute bake, while halves or quarters give the finished filling more texture and recognizable fruit.
Rhubarb varies in tartness, but the listed 1/2 cup of sugar balances it with the strawberries while allowing their bright flavor to come through. Stir the filling gently rather than letting it sit for a long time before baking, since the fruit will naturally release juice as it stands.
For an especially attractive finish, spoon the crisp into shallow bowls so each portion includes colorful fruit and plenty of crumble. A cool, creamy topping provides a wonderful contrast to the warm filling; for a refreshing dessert pairing, see this peach sorbet recipe.
Serving Suggestions
Serve the crisp warm after its resting time, preferably in generous spoonfuls with the juices gathered beneath the topping. Vanilla ice cream is the classic choice because it melts into the fruit, but whipped cream and plain yogurt are also excellent.
- Add a scoop of vanilla ice cream for a cold-and-warm contrast.
- Use lightly sweetened whipped cream when you want a soft, airy finish.
- Choose plain yogurt for a tangy breakfast-style serving.
- Pair smaller portions with coffee or tea after dinner.
The crisp is sweet enough to feel like a proper dessert but bright enough to avoid tasting heavy. If you are planning a larger dessert spread, a slice of bright key lime pound cake can bring another citrusy note to the table.
Storage and Reheating
This crisp is usually best the day it is baked, when the topping is at its freshest and most textured. Once completely cooled, cover it and refrigerate leftovers for about 3–4 days.
To serve leftovers, spoon out a portion and warm it gently until heated through. The topping may soften slightly in the refrigerator, but the fruit will remain flavorful and the dessert will still be delicious with a fresh scoop of ice cream.
For the best texture when serving guests, prepare and bake it close to mealtime, then allow the required 15-minute rest. That short cooling period is long enough for the filling to thicken while keeping the topping pleasantly warm.
Recipe Questions Answered
Can I use quick oats? Old-fashioned rolled oats are recommended because they provide a more satisfying chew and a rustic crumble. Quick oats can produce a finer, less textured topping.
Why does the crisp need to rest? The fruit releases abundant juice while it bakes, and the cornstarch needs time to thicken that liquid. Serving immediately can make the filling appear overly runny.
What should the fruit look like when it is done? Look for bubbling juices around the edges of the baking dish and softened fruit beneath a golden-brown topping. Those visual cues are more useful than judging the fruit by color alone.
Can I serve it for breakfast? Absolutely. A warm portion with plain yogurt makes a satisfying morning treat, while ice cream or whipped cream turns the same recipe into a classic after-dinner dessert.
For a savory make-ahead contrast on a seasonal menu, consider adding a small dish of pickled okra alongside lunch or a picnic spread.
