How to Make Rhubarb Strawberry Crisp
Ingredients
- 2 cups rhubarb, chopped
- 2 cups strawberries, sliced
- 1 cup granulated sugar
- 1 tablespoon cornstarch
- 1 teaspoon vanilla extract
- 1 cup rolled oats
- 1 cup all-purpose flour
- 1/2 cup brown sugar
- 1 teaspoon cinnamon
- 1/2 cup butter, melted
- Vanilla ice cream (for serving)

Directions
Preheat the oven to 350°F (175°C). This allows your crisp to bake evenly and develop that beautiful golden-brown crust.
In a large mixing bowl, combine the chopped rhubarb, sliced strawberries, granulated sugar, cornstarch, and vanilla extract. Fold gently until the fruit is well-coated. Pour this luscious mixture into a greased 9×13-inch baking dish, spreading it evenly.
In another bowl, mix together the rolled oats, flour, brown sugar, and cinnamon. Drizzle the melted butter over the dry ingredients and stir until the mixture becomes crumbly.
Sprinkle the oat mixture evenly over the fruit filling. Ensure that it covers the fruit completely for a delightful texture contrast.
Bake in the preheated oven for 25-30 minutes, or until the topping is golden brown and the fruit is bubbling at the edges. Your kitchen will fill with delicious aromas as it cooks.
Serve warm with a generous dollop of vanilla ice cream on top, allowing it to melt delightfully into the crisp.
How to Serve Rhubarb Strawberry Crisp
Rhubarb Strawberry Crisp is best enjoyed warm but can also be delightful at room temperature. When serving, consider using a rustic-style bowl to enhance its homemade charm. Pair it with crispy biscuits or even a refreshing sorbet for an exciting contrast in flavors. To elevate the presentation, garnish with fresh mint leaves or a sprinkle of powdered sugar.
This dessert is perfect for backyard barbecues, holiday get-togethers, or a simple weeknight treat to enjoy while watching your favorite show.
How to Store Rhubarb Strawberry Crisp
To store your Rhubarb Strawberry Crisp, transfer it to an airtight container and place it in the refrigerator, where it can keep fresh for 3-4 days. If you have leftovers, you can freeze the crisp for up to three months. Wrap it tightly in plastic wrap or store it in a freezer-safe container. When you’re ready to enjoy it again, thaw it overnight in the refrigerator and reheat in the oven at 350°F (175°C) for about 15-20 minutes, until warmed through.
Make sure to check for any signs of spoilage before consuming leftovers. If the filling has an off smell or visible mold, it’s best to discard it. Additionally, consider making a double batch ahead of time so you always have this delicious treat on hand for spontaneous dessert cravings.
Tips to Make Rhubarb Strawberry Crisp
Prep Ingredients Ahead: To save time, chop the rhubarb and slice the strawberries a day in advance. Keep them in an airtight container in the refrigerator until you’re ready to bake.
Use Frozen Fruits: If fresh rhubarb or strawberries aren’t available, feel free to use frozen ones. Just increase the cooking time a bit, as they may release more moisture.
Don’t Overmix: When combining the crumble topping ingredients, mix just until crumbly. Overmixing can lead to a dense texture instead of the light, crispy topping you desire.
Choose Just-Ripe Fruit: Select fruits that are ripe but not overripe for the best flavor and texture in your filling.
Add Nuts for Crunch: For extra crunch, consider adding chopped pecans or walnuts into the oat topping.
Avoid Soggy Crisp: Make sure to drain excess juice from the fruits, especially if you use thawed frozen strawberries, to avoid a soggy bottom.
Flavor Boost: Incorporate a teaspoon of lemon zest or almond extract into the fruit mixture for an extra layer of flavor.
Use Quick Oats for a Different Texture: If you prefer a finer crumb topping, substituting quick oats for rolled oats can give you that.
Adapt for Dietary Needs: Gluten-free oats and flour can easily replace standard varieties, making this dish friendly for those with gluten sensitivities.
Turn Leftovers into Parfaits: Layer leftover crisp with yogurt and fresh fruit to create a delightful breakfast or snack option.
Variations
Berry Bliss Rhubarb Crisp
Add a medley of berries such as blueberries and raspberries to the mix for an explosion of color and flavor. The variety of berries will accentuate the tartness of the rhubarb while providing a fun texture.
Tropical Citrus Rhubarb Crisp
Incorporate a splash of orange juice and zest, along with coconut flakes in the topping to create a tropical twist. This version will bring sunny vibes to your dessert table any time of year.
Nutty Caramel Swirl Crisp
Before baking, swirl in your favorite caramel sauce into the fruit mixture. Top it with pecans for added richness, making this crisp decadently delicious.
Spiced Apple Rhubarb Crisp
Mix in diced apples along with your rhubarb and strawberries, adding a teaspoon of nutmeg to the fruit mixture for a warm, spiced flavor profile. This version is especially comforting during the fall.
Vegan Rhubarb Strawberry Crisp
Replace butter with coconut oil and use maple syrup in place of granulated sugar to create a plant-based version. Ditch the ice cream and substitute with coconut yogurt for creaminess.
FAQs
Can I make this ahead of time?
Absolutely! You can prepare the fruit filling and crisp topping separately, storing them in the refrigerator for up to one day in advance. When you’re ready to bake, assemble and place in the oven as directed.
How do I store leftovers?

What can I substitute for cornstarch?
You can replace cornstarch with an equal amount of all-purpose flour or arrowroot powder. The substitution may slightly alter the crisp’s thickness but will still yield a delicious dessert.
How do I prevent the topping from burning?
To avoid burning the topping, you might place a piece of aluminum foil over the crisp during baking for the first half to keep it from browning too quickly.
