Best Strawberry Rhubarb Crisp Recipe
You can’t go wrong with this sweet and tart rhubarb crisp with strawberries and a crunchy oat topping. Rhubarb is actually a vegetable that grows a bit like celery stalks early in the spring. It's usually bright red or pink and has a very sour flavor, which is why it is often made into sweet desserts like pies, cobblers, and crisps.
Strawberries are a common fruit to pair with rhubarb partially because they grow at the same time during the spring. But, strawberries also add a little extra bright red color and the sweetness creates a sweet and sour combo that is so perfect.
Not only is this rhubarb dessert delicious—it couldn’t be simpler to throw together. Just toss the prepared strawberries and rhubarb with sugar, cornstarch, lemon juice, and a little sea salt, then top with a super simple cinnamon oat crumble. Bake until bubbly, serve with a big scoop of vanilla ice cream, and you’re good to go.

Key Ingredients
- Strawberries - use fresh ripe strawberries that are washed, hulled, and quartered.
- Rhubarb - there’s no need to peel your rhubarb. Just cut into small pieces and toss with the strawberries. You can often find it fresh at the grocery store starting around late March through the rest of the spring and early summer.
- Cornstarch - this helps to thicken the fruit mixture and keep the crisp topping from getting too soggy. If you don’t have cornstarch you could use flour instead.
- Sugars - I like to use a combination of both granulated sugar and light brown sugar for the fruit filling. You could absolutely substitute just granulated sugar or add in a touch of honey.
- Lemon Juice - fresh lemon juice really balances out the flavors.
Oat Crumble Topping
- Butter - room temperature butter works great for making the crisp topping. If you use salted butter just reduce the additional salt slightly.
- Brown Sugar - I prefer light brown sugar for this recipe but you can use dark brown sugar if you prefer the flavor.
- Cinnamon - I love cinnamon for this recipe, but you could use other baking spices including cardamom, cloves, or nutmeg.
- Oats - be sure to use old-fashioned rolled oats or quick-cooking oats because they will give the crumb topping a slightly chewy texture. Avoid steel-cut oats!

How to Make This Strawberry Rhubarb Crisp
- Make the strawberry and rhubarb compote mixture. In a large mixing bowl combine the strawberries, rhubarb, cornstarch, brown sugar, granulated sugar, and lemon juice. Toss to evenly coat the fruit. Transfer the mixture to a 9" x 9" baking dish, or a 10" cast iron skillet.
- Make the oat crumble topping. In the bowl of a stand mixer, add the softened butter, flour, brown sugar, cinnamon, nutmeg, salt, and oats. Mix on low speed until the mixture forms about ½" chunks.
- Add the crumb topping. Using your fingers, sprinkle the oat topping evenly over the fruit mixture.
- Bake. Bake in a preheated 400 degree oven for 35-45 minutes, or until the topping is golden brown and the mixture is bubbly.
- Serve. Remove from the oven and serve warm with a big scoop of vanilla ice cream or fresh whipped cream. Enjoy!

Frequently Asked Questions
More than likely, your Strawberry Rhubarb crisp is runny because it’s still hot. Straight out of the oven, it will be fairly runny. As it cools, the cornstarch helps to solidify the mixture and you will notice it starting to set up.Â
Both a crisp and crumble involve a fruit mixture baked in the oven with some sort of topping. A crumble topping is typically more like a biscuit while a crisp topping is generally made from an oat crumble.Â
While it’s fine to let your Strawberry Rhubarb crisp sit out at room temperature for up to even 24 hours, I recommend storing it covered in the fridge so that it stays fresh. After sitting out for too long, the filling will begin to warm and loosen. When that happens, the topping will absorb more and more of the moisture from the filling and it begins to get a bit soggy.
Storing And Reheating Instructions
- Room Temperature: cover any leftover crisp with aluminum foil and store at room temperature for up to 2 days.
- Refrigerator: you can also cover and refrigerate your crisp for up to 5 days.
- To reheat: you can microwave a small portion or reheat in a 350 degree oven for about 15 minutes, or until warmed through.
- Freezing: if you want to freeze, I recommend freezing the oat topping and fruit mixture separately in airtight containers for up to 2 months. When you want to bake your crisp, pull from the freezer and transfer to a baking dish before baking as directed.
