There’s something magical about the first warm days of spring when fresh strawberries and tangy rhubarb appear at the farmers market together. That’s when I know it’s time to make my favorite strawberry rhubarb crisp—a dessert that celebrates the season with its perfect balance of sweet berries and tart rhubarb underneath a golden, buttery oat topping.

What I love most about this strawberry rhubarb dessert is how the oat topping gets crispy and golden while the fruit filling stays tender and juicy. It’s comfort food at its finest, and the aroma while it’s baking will have everyone in your house asking what smells so incredible.

Ingredients You’ll Need
The foundation of a great strawberry rhubarb crisp starts with quality ingredients, but nothing complicated or hard to find. Fresh strawberries and rhubarb are your stars here, and I always recommend using what’s in season at your local farmers market. If you can’t find fresh rhubarb, frozen works beautifully—there’s no need to thaw it before using. The filling gets sweetened with a combination of sugar and a touch of cornstarch, which helps thicken the juices without making it goopy.
For the rhubarb crisp topping, we’re keeping things simple with pantry staples: rolled oats, brown sugar, flour, butter, and a pinch of salt. That’s it! Some recipes complicate this by adding nuts or excessive spices, but I’ve found that simplicity lets the fruit shine. If you do want to add nuts or cinnamon to your version, absolutely go for it—this recipe is forgiving enough to handle variations.
For the Fruit Filling
- 4 cups fresh strawberries (hulled and halved (about 1.5 lbs))
- 3 cups fresh rhubarb (cut into 1-inch pieces (about 1 lb, 3-4 stalks))
- 3/4 cup granulated sugar
- 2 tablespoons cornstarch (prevents excess liquid)
- 1 tablespoon fresh lemon juice
- 1/4 teaspoon sea salt
For the Oat Crisp Topping
- 1.5 cups rolled oats (old-fashioned, not instant)
- 3/4 cup all-purpose flour (or gluten-free flour blend)
- 2/3 cup packed brown sugar
- 6 tablespoons unsalted butter (cold, cut into small cubes)
- 1/4 teaspoon sea salt
Optional Add-ins:
- ground cinnamon
- sliced almonds or chopped pecans
- vanilla extract
- fresh mint leaves
How to Make Strawberry Rhubarb Crisp Recipe (Step-by-Step)
1. Prep Your Ingredients
Preheat your oven to 375°F and position the rack to the middle of the oven. This ensures even baking of both the fruit filling and the crispy topping.
Pro tip: Starting with a preheated oven prevents the fruit from releasing too much liquid before the topping has a chance to cook.
Prepare your fruit: wash and hull the strawberries, then cut them in half. Cut the rhubarb into 1-inch pieces, discarding any leaves (which are toxic). If your rhubarb pieces are particularly thick, cut them lengthwise first to ensure even cooking.
Pro tip: Rhubarb leaves contain oxalic acid and should never be consumed, so discard them completely.
2. Make the Fruit Filling
In a large mixing bowl, combine the prepared strawberries and rhubarb. Sprinkle the granulated sugar, cornstarch, lemon juice, and sea salt over the fruit.
Pro tip: The cornstarch is crucial in a strawberry rhubarb crisp—it absorbs excess liquid without making the filling taste starchy or weird.
Gently toss the mixture until everything is evenly coated. Try not to crush the strawberries; you want some texture in your finished dessert. Let the filling sit for 5 minutes to allow the sugar to start dissolving.
Pro tip: This short wait helps the filling develop more flavor and prevents the crisp topping from burning before the fruit cooks through.
Pour the fruit mixture into your prepared 9×13 inch baking dish, spreading it evenly into a single layer. The fruit should fill the dish about three-quarters full.
Pro tip: A slightly overfilled dish is fine—the strawberry rhubarb crisp topping will settle as it bakes.
3. Create the Crisp Topping
In a medium mixing bowl, whisk together the rolled oats, all-purpose flour, brown sugar, and sea salt. If you’re adding cinnamon or other spices, mix them in at this point.
Pro tip: Using old-fashioned rolled oats instead of instant oats gives this rhubarb crisp topping the best texture—chewy in the middle and crispy on the edges.
Add the cold butter cubes to the dry ingredients. Using a pastry cutter, two forks, or your fingertips, work the butter into the mixture until it resembles coarse breadcrumbs. This should take about 2-3 minutes.
Pro tip: Cold butter is absolutely essential here—it creates pockets of steam that make the topping crispy rather than dense. If your kitchen is warm, refrigerate the butter cubes for 10 minutes before using.
Sprinkle the crisp topping evenly over the fruit filling, pressing down very gently so it holds together slightly but remains somewhat loose. An easy strawberry rhubarb crisp should have a rustic, chunky topping, not a smooth crust.
Pro tip: Don’t press too firmly—you want the topping to stay airy and crispy, not compact into a dense layer.
4. Bake to Golden Perfection
Place the strawberry rhubarb crisp in the preheated 375°F oven for 35-40 minutes, until the topping is golden brown and the fruit filling is bubbling around the edges.
Pro tip: Every oven is slightly different, so start checking at 35 minutes. The top should be deep golden brown, not pale.
Remove from the oven and let it cool for 10-15 minutes before serving. This resting time allows the filling to set slightly, making it easier to serve without it being too runny.
Pro tip: If you serve it too hot, the filling will be very liquid; too cool and you’ll miss that wonderful warm, gooey texture that makes this homemade rhubarb crisp recipe so special.
5. Serve and Enjoy
Scoop generous portions of the strawberry rhubarb crisp into bowls or onto plates. Top with a dollop of vanilla ice cream, whipped cream, or Greek yogurt for the ultimate experience.
Pro tip: This fruit crisp recipe is even better when served warm, but it’s also delicious at room temperature or straight from the refrigerator.

Tips for the Best Strawberry Rhubarb Crisp Recipe
- Frozen Fruit Works Perfectly: Don’t have fresh rhubarb? Frozen rhubarb thaws during baking and works beautifully in this easy strawberry rhubarb crisp. You can even use frozen strawberries in a pinch, though fresh gives better texture.
- Adjust Sweetness to Your Taste: If your rhubarb is particularly tart or your strawberries aren’t very sweet, add another 2 tablespoons of sugar to the fruit filling. You want a balance of sweet and tart in your strawberry rhubarb dessert.
- Brown Sugar is Your Secret Weapon: Using brown sugar instead of white sugar in the rhubarb crisp topping adds molasses depth and helps create that perfect chewy-crispy texture.
- Keep Butter Cold: This is the secret to a truly crispy topping. Warm butter creates a dense, cake-like topping instead of the light, crunchy texture that makes this fruit crisp recipe spectacular.
- Make-Ahead Magic: Assemble your strawberry rhubarb crisp completely in the baking dish up to 4 hours ahead, then cover and refrigerate. Bake when ready—it might take an extra 5 minutes since it’s coming from the cold.
- Don’t Skip the Lemon Juice: Just one tablespoon brightens the entire strawberry rhubarb crisp, balancing the sweetness and making the flavors pop.
Variations to Try
- Strawberry Rhubarb Crisp with Almonds: Mix 1/2 cup of sliced or chopped almonds into the oat topping for extra crunch and a subtle nutty flavor that pairs beautifully with the fruit.
- Spiced Version: Add 1/2 teaspoon ground cinnamon and 1/4 teaspoon ground ginger to the oat crisp topping for a warmer, more complex flavor profile.
- Brown Butter Topping: For serious flavor, brown your butter before adding it to the dry ingredients. This adds a nutty, sophisticated depth to your strawberry rhubarb dessert.
- Coconut Variation: Substitute 1/3 cup of the oats with shredded coconut for a tropical twist on this classic spring dessert recipe.
- Individual Ramekin Crisps: Divide the fruit filling among 6-8 individual ramekins, top with the crisp mixture, and bake for 20-25 minutes for elegant single-serve portions.
Storage and Meal Prep Tips
- Refrigerator Storage: Keep your covered strawberry rhubarb crisp in the refrigerator for up to 4 days. It’s actually delicious cold or at room temperature, and the filling becomes more syrupy as it sits.
- Freezer Instructions: This homemade rhubarb crisp recipe freezes beautifully! You can freeze it unbaked (covered tightly with plastic wrap and foil) for up to 2 months, then bake directly from frozen—just add 10-15 minutes to the baking time.
- Reheating Tips: To reheat, cover loosely with foil and warm in a 325°F oven for about 15 minutes until heated through. This prevents the topping from burning while you warm the fruit filling.
- Single Servings: For meal prep, portion individual servings into airtight containers. They’ll keep for 3-4 days and can be reheated in the microwave for 30-45 seconds.
- Best Served: While this easy strawberry rhubarb crisp keeps well refrigerated, it’s always best served warm or at room temperature with a scoop of ice cream on top.
Nutritional Benefits
This strawberry rhubarb dessert isn’t just delicious—it provides genuine nutritional value thanks to the fresh fruit. Strawberries are packed with vitamin C, antioxidants, and fiber, while rhubarb contributes calcium and additional fiber. The oat-based topping adds soluble fiber and B vitamins. While this is still a dessert and should be enjoyed in moderation, it’s a significantly healthier choice than many other sweet treats, especially when you opt for the Greek yogurt topping instead of ice cream.
- Strawberries provide over 100% of daily vitamin C per serving
- Rhubarb is an excellent source of dietary fiber and calcium
- Oats contain beta-glucans, a type of soluble fiber linked to heart health
- Fresh fruit filling means no artificial preservatives or additives
- One serving contains about 5 grams of fiber from the fruit and oats combined
What to Serve With Strawberry Rhubarb Crisp Recipe
- Vanilla Ice Cream: The classic pairing—warm strawberry rhubarb crisp with cold, creamy vanilla ice cream is pure heaven. The temperature and flavor contrast makes this combination absolutely irresistible.
- Greek Yogurt: For a lighter option that still adds creaminess, top this fruit crisp recipe with tangy Greek yogurt. It complements the tart rhubarb beautifully.
- Whipped Cream: Homemade or store-bought whipped cream adds a luxurious touch. A dollop of whipped cream with a sprinkle of fresh mint makes even a simple dessert feel special.
- Custard Sauce: A silky custard sauce poured over warm strawberry rhubarb crisp elevates this spring dessert into restaurant-quality territory.
- Mascarpone Dollop: Rich, slightly sweet mascarpone cheese is a sophisticated topping that lets the fruit flavors shine through.
Frequently Asked Questions
Can I make a strawberry rhubarb crisp without oats?
Absolutely! You can replace the oats with an equal amount of flour and add an extra 2 tablespoons of butter to maintain the crispy texture. Alternatively, use crushed nuts like almonds or pecans for a different texture. However, the oat version creates the most traditional crisp topping with the best balance of crispy and chewy.
Why is my strawberry rhubarb crisp too watery?
The most common reason is not enough cornstarch. The cornstarch thickens the fruit juices, so if your crisp is soupy, try adding another tablespoon of cornstarch to future batches. Also ensure you’re using old-fashioned oats in the topping, as they absorb some liquid. Finally, let the crisp rest for 10-15 minutes after baking before serving—this allows the filling to set.
Can I use all strawberries or all rhubarb instead?
You can! An all-strawberry version works great—use 7-8 cups of strawberries and reduce the sugar slightly since strawberries are naturally sweeter. An all-rhubarb version will be more tart, so increase the sugar to 1 cup and add an extra tablespoon of lemon juice. However, the combination of strawberry and rhubarb creates the best flavor balance.
How far in advance can I assemble the strawberry rhubarb crisp?
You can assemble the entire crisp up to 4 hours before baking. Simply cover it with plastic wrap and refrigerate until you’re ready to bake. The only note is that it may take an extra 5 minutes to bake since it starts cold. You cannot assemble it and leave it at room temperature for more than 30 minutes due to food safety.
Is strawberry rhubarb crisp gluten-free?
The filling is naturally gluten-free, and the topping becomes gluten-free when you substitute the all-purpose flour with a gluten-free flour blend and use certified gluten-free oats. The ratio stays exactly the same—just swap one for the other. I recommend King Arthur Baking Company’s gluten-free flour blend for best results.
