Strawberry-Rhubarb Crisp

A strawberry-rhubarb crisp is a summer dessert dream. We start ours by lining the pan with a thick, oaty crumble. We then add an abundance of in season, sun-ripened strawberries and tart pieces of rhubarb on top, and cover the fruit with a generous helping of that same crumb topping.

It’s one of those rare recipes that’s basically foolproof to pull off even if you’re a “better cook than baker” kind of person. We’re with you every step of the way making this strawberry-rhubarb crisp recipe, so let’s dive in.

Strawberry-Rhubarb Crisp Ingredients

Taste of Home

• All-purpose flour: We use all-purpose flour to thicken up the crisp topping.
• Oats: Make sure you’re buying quick-cooking oats instead of rolled oats or any other type of oats. They’re not quite the same, and the difference will affect the texture of the crisp.
• Cinnamon: Sweet cinnamon adds warmth to the rhubarb-strawberry crisp to offset the bright, tart flavors.
• Strawberries: Sometimes dirt and bugs can linger on a strawberry, and running the berry under cool water isn’t enough to remove them. Instead, try washing your strawberries in salt water to draw them out.
• Rhubarb: Fresh or frozen rhubarb is fine for this recipe. Use whatever is most accessible for you.
• Cornstarch: We use cornstarch to create a gorgeous, velvety sauce that cooks with the strawberries and rhubarb.

Recipe Variations

• Sub out the rhubarb: Can’t find rhubarb? Use another tart fruit, like blackberries, raspberries, cherries or green apples.
• Go gluten-free: Avoiding gluten? Swap the all-purpose flour for your favorite gluten-free flour blend, and make sure to buy certified gluten-free oats.
• Make it vegan: Need to make this strawberry-rhubarb crisp recipe plant-based? We got you! Swap the butter out for your fave vegan butter brand, use coconut sugar instead of brown sugar, and sub out the granulated sugar for cane sugar. Don’t forget the vegan ice cream!

How to Store Strawberry-Rhubarb Crisp

To store, cool the crisp to room temperature, then wrap the pan in storage wrap. Keep it in the fridge for up to three days and reheat in the microwave when you’re ready to enjoy.

What do I serve with strawberry-rhubarb crisp?

A rhubarb-strawberry crisp is a substantial dessert all on its own, but a scoop of vanilla ice cream or dollop of whipped cream brings a smooth richness to the bright, fruity and crunchy dessert. Pair it with a glass of Riesling or Moscato d’Asti, and enjoy outside on a warm evening.

Where can I find rhubarb?

Rhubarb is in season at the beginning of April and trails off in early June. Look for bright-pink rhubarb stalks at the farmers market or in the produce section of your grocery store. If you’re searching for rhubarb in the off season, check the frozen aisle.
