Strawberry rhubarb crisp summer is hands-down my favorite way to use peak-season berries without heating up the kitchen for hours. This dessert comes together in just 20 minutes of prep, then the oven does all the work while you relax with guests.
The combination of tart rhubarb and sweet strawberries creates this perfect balance that honestly gets better when you add vanilla ice cream on top. Unlike other desserts, this one actually tastes better the next day because the filling settles into the crispy topping.
I’m obsessed with how forgiving this recipe is — you can prep it in the morning and bake it right before dinner. Plus, it feeds a crowd without stress. Bookmark this for your next summer entertaining moment!
If you love seasonal fruit desserts, you’ll also want to try making strawberry blueberry clafoutis for an elegant French summer dessert option that impresses just as much.

Ingredients for strawberry rhubarb crisp summer
- 4 cups fresh strawberries hulled and sliced
- 2 cups rhubarb trimmed and chopped
- 1 cup granulated sugar
- 1/2 cup light brown sugar
- 2 tbsp lemon juice
- 1 tsp vanilla powder
- 1/4 tsp salt
- 1 cup rolled oats
- 1/2 cup all-purpose flour
- 1/2 cup unsalted butter melted
- 1/3 cup chopped walnuts
- 1 tsp ground cinnamon
The beauty of this strawberry rhubarb crisp summer is that you can swap berries based on what’s fresh at your market. I’ve made this with raspberries mixed in, and honestly, it’s fantastic — just use the same total amount of fruit.
For the topping, don’t skip the walnuts because they add this amazing crunch factor. If you’re nut-free, swap them with the same amount of chopped pecans or just leave them out entirely (yes really — it still tastes great).
Step-by-step instructions
1. Preheat your oven to 375°F and grab a 9×13-inch baking dish. In a large bowl, combine the sliced strawberries, chopped rhubarb, 1 cup granulated sugar, 1/2 cup brown sugar, 2 tbsp lemon juice, vanilla powder, and 1/4 tsp salt. Stir gently until everything coats with the sugar mixture — don’t mash it up.
2. Pour the fruit mixture into your prepared baking dish and spread it evenly. The filling will look kinda liquidy right now, but that’s exactly what you want — trust me on this. Let it sit while you make the topping.
3. In another bowl, mix together 1 cup rolled oats, 1/2 cup all-purpose flour, 1/3 cup chopped walnuts, 1 tsp ground cinnamon, and 1/4 tsp salt. These dry ingredients are the foundation of your crispy topping, so don’t skip mixing them first.
4. Pour 1/2 cup melted butter over the oat mixture and stir until everything looks like crumbly sand. This is the step that creates those golden crispy pieces everyone loves. If it seems dry, add a splash more melted butter — you want it moist but not soggy.
5. Sprinkle the oat topping evenly over your fruit filling, making sure to cover all the strawberry rhubarb crisp filling. Don’t pack it down — let it stay loose and chunky because that’s what creates the crispy texture. You’ll hear it sizzle when it hits the hot filling.
6. Bake for 35-40 minutes until the topping turns golden brown and you can see the fruit bubbling up around the edges. My oven runs hot, so I check mine around minute 35 — don’t panic if the edges bubble more than the center. That’s completely normal and actually means it’s cooking perfectly.
7. Remove from the oven and let it cool for about 10 minutes before serving. I know it’s tempting to dig in right away, but this resting time lets the filling set slightly so it’s not watery when you scoop it.
Serving ideas for strawberry rhubarb crisp summer
This dessert shines when you give it the right accompaniments — here’s how to make it absolutely irresistible.
Vanilla ice cream pairing
Top each warm serving with a generous scoop of vanilla ice cream and watch it melt into all those buttery crumbs. The cold-hot contrast makes this seasonal summer crisp taste like restaurant-quality dessert. Honestly, vanilla is non-negotiable here.Whipped cream and fresh mint
Skip the ice cream and dollop whipped cream on top, then garnish with fresh mint leaves for a lighter summer vibe. I personally think this works better when the crisp has cooled to room temperature. The tartness of the rhubarb really pops against the cream.Make it a dessert situation
Serve this warm with strawberry shortcake biscuits on the side for an over-the-top elegant presentation. Your guests will think you spent hours in the kitchen when this took literally 60 minutes total. Layer the biscuits, crisp, and whipped cream for a showstopper.Pro tips for perfect strawberry rhubarb crisp summer
Storage tips
– Keep leftovers in an airtight container in the fridge for up to 4 days – The crisp actually stays crunchier than you’d expect when stored properly – Reheat individual portions in the microwave for 30 seconds before servingMake-ahead instructions
– Prep the fruit filling the night before and store it covered in the fridge – Mix the topping 2 hours ahead — don’t add the butter until just before baking – You can assemble everything and bake it straight from the fridge (add 5 minutes to bake time)Variations
– Try peaches instead of strawberries for a different flavor profile entirely – Add 1/2 cup coconut flakes to the topping for tropical vibes – Mix in 2 tbsp honey with the fruit for extra sweetness if rhubarb tastes too tart – Use almonds instead of walnuts for a milder, slightly sweeter crunchTroubleshooting
– If the topping seems soggy after baking, you used too much melted butter — use slightly less next time – When the filling looks watery before baking, that’s normal and it’ll thicken as it cooks – If the topping browns too fast, cover loosely with foil for the last 15 minutesFrequently asked questions
Can I freeze strawberry rhubarb crisp summer?
Yes, absolutely — freeze the unbaked crisp covered with plastic wrap and foil for up to 2 months. Bake it straight from frozen, but add 10-15 minutes to your baking time and cover with foil if the topping browns too quickly. The texture stays great when frozen this way.
What if my rhubarb tastes too sour?
Add another 1/4 cup sugar to the filling if your rhubarb batch is particularly tart. Some rhubarb varieties are naturally more sour than others, so taste the filling mixture before baking and adjust. The strawberries provide sweetness, but they can’t mask overly sour rhubarb.
How do I reheat leftovers?
Pop individual servings in a 325°F oven for 8-10 minutes until warm throughout, or microwave for 45-60 seconds for quicker reheating. The oven method keeps the topping crispier, but the microwave works fine if you’re in a hurry. Both methods taste delicious — it’s just your preference.
Can I make this without walnuts?
Totally — just skip the walnuts and increase the oats to 1 1/4 cups to keep the same texture. The crisp works beautifully without nuts, and you’ll still get that golden, buttery crunch everyone loves. Some people add chopped pecans or almonds instead, which works just as well.
