If you’re looking for an easy spring or summer dessert, this Strawberry Rhubarb Crisp Recipe is it. My mom’s version pairs a sweet-tart, jamlike fruit filling with a buttery oat topping – and adds a hint of fresh basil for a subtle twist. She also blended the topping in a food processor, giving it a more refined texture that’s less chewy. It’s easy to prep, make-ahead friendly, and always a hit!
A Family Favorite, With a Twist
My mom loved rhubarb and always grew it in her garden. Every spring, she’d pull out her favorite rhubarb recipes – like her Old Fashioned Rhubarb Custard Pie, Rhubarb Bread (you’ll find that one in A Well-Seasoned Kitchen®), and this delicious Strawberry Rhubarb Crisp. She was particular about texture and didn’t care for a crisp topping that was too coarse or chunky. So, she used quick-cooking oats and whirled the topping ingredients together in a food processor. It not only made the prep easier, it also created a finer, more cohesive topping with a softer bite.
Why You’ll Love This Easy Strawberry Rhubarb Crisp
- Classic comfort with a twist. Sweet strawberries and tart rhubarb are a timeless combo, and the touch of fresh basil brings out the fruit’s flavor in a subtle, unexpected way.
- Softer, more refined topping. Blending the oat topping in a food processor creates a finer texture that’s more cohesive and less chewy.
- Perfect texture. The fruit bakes into a jamlike filling with tender chunks and a thick sauce, while the topping turns golden and crumbly.
- Quick and easy to make. With a food processor doing most of the work, the topping comes together in minutes.
- Make-ahead friendly. Prep and bake it up to 24 hours ahead, then just rewarm before serving (or serve at room temperature). It’s flexible and low-stress.
- Always a crowd favorite. Familiar and comforting, with just enough of a twist to make it memorable.
Quick Tip
Rhubarb is technically a vegetable (it’s the stalk of a plant in the buckwheat family), but because it’s usually baked into sweet dishes like pies and crisps, it’s treated like (and referred to as) a fruit in the kitchen. So, I’m calling it a fruit here, just like Mom did!
Ingredients in This Strawberry Rhubarb Crisp Recipe
Here’s what you’ll need to make this easy and flavorful fruit crisp (exact quantities and ingredient prep are in the recipe card below):
- Fresh rhubarb – Look for firm, crisp stalks with bright color and no blemishes. (Check out my other recommendations about buying, storing, and using rhubarb.)
- Fresh strawberries – Look for bright red berries with firm flesh and healthy green tops.
- Fresh basil – Brightens the fruit flavors.
- Granulated sugar –Sweetens the filling and balances the tart rhubarb.
- Cornstarch – Thickens the fruit juices into that perfect jamlike consistency.
- Ground cinnamon – Adds a subtle warm note to the filling.
- All-purpose flour – Helps bind the topping ingredients.
- Quick-cooking oats – Create a finer, more tender topping when pulsed in the food processor.
- Light brown sugar – Brings sweetness and a hint of molasses to the crisp topping.
- Kosher or sea salt –Enhances all the flavors.
- Unsalted butter – Cold and cut into pieces, it binds the topping and makes it golden and crisp.
- Vanilla ice cream or whipped cream – Optional for serving, but highly recommended!
Ingredient Substitutions and Variations
- Dried basil – I prefer using fresh basil, but you can use dried. It’s more concentrated in flavor, so use just 2 teaspoons.
- Old-fashioned oats – They’ll work, but the topping will be more textured and rustic. Mom preferred quick oats for a softer finish.
- Add toasted nuts to the topping – Stir in 1/4 to 1/3 cup chopped toasted pecans, walnuts, or almonds for extra crunch and flavor.
- Add citrus zest to the filling – Stir in 1 to 2 teaspoons of lemon zest or orange zest. It adds a fresh, brightness that enhances the fruit flavor.

How to Serve This Recipe for Strawberry Rhubarb Crisp
Serve this fruit crisp either warm or at room temperature. I like to top each serving with a scoop of vanilla ice cream or a generous dollop of freshly whipped cream. The cool, creamy topping melts slightly over the warm fruit and crumbly topping – pure comfort food yum!
Tips for Making the Best Strawberry Rhubarb Crisp Recipe
- Use cold cubed butter. Cut the butter into 1/2-inch cubes and chill it before adding to the food processor. This helps create that crumbly, tender topping.
- Don’t overprocess the topping. After adding the butter, pulse just until the mixture looks like coarse crumbs. Overprocessing will cause it to clump together, resulting in a denser, doughier topping instead of one that’s light and crisp.
- Bake right after assembling. Don’t assemble the crisp ahead of time. As it sits, the sugar in the filling draws out moisture from the fruit (a process called maceration), which can make the filling runny and the topping soggy.
Make Ahead
Day of: You can bake the crisp up to 2 hours ahead, cool, cover, and leave it at room temperature until ready to serve. It’s delicious served at room temperature, or you can rewarm it in a preheated 300 degree F oven for 10 to 15 minutes.
Day before: Up to 24 hours ahead, you can bake the crisp, let it cool completely, then cover and refrigerate. You can either reheat it in a preheated 300 degree F oven for 15 to 20 minutes, or let it come to room temperature to serve.
Up to 2 months ahead (freezer option): Bake the crisp, let it cool completely, then wrap tightly with plastic wrap and aluminum foil. Freeze for up to 2 months. To serve, thaw overnight in the refrigerator, then reheat in a preheated 300 degree F oven for 15 to 20 minutes. The topping may soften slightly, but the flavor holds up beautifully.
Don’t assemble the crisp ahead of time without baking. As it sits, the sugar draws moisture from the fruit (a process called maceration), which can make the filling runny and the topping soggy.
How to Store Strawberry Rhubarb Crisp
Once cooled, cover the crisp and store in the refrigerator. It will keep well for up to 3 days. Reheat individual portions in the microwave or warm larger portions in a preheated 300 degree F oven until heated through.

You can use frozen strawberries and frozen rhubarb, just don’t thaw the fruit first – use it straight from the freezer. Add around 1 extra tablespoon of cornstarch to help thicken the extra juices released during baking. Note that frozen fruit may make the filling slightly more runny than fresh, and will increase the bake time.
Yes, after baking. Let it cool completely, then wrap well and freeze for up to 2 months. Thaw overnight in the fridge and reheat in a preheated 300 degree F oven until warmed through. Freezing the unbaked crisp isn’t recommended, as the topping can get soggy and the filling watery.
