Strawberry rhubarb crisp

Growing up, my family had a massive rhubarb plant in our backyard. It’s quite an ugly plant really, like a monstrous weed with thick leaves and stalks. But every year my mom would harvest the pink-ish green stalks and make a rhubarb crisp. And man, was it heavenly! It reminded me of a watermelon jolly rancher, neon pink and intensely sweet tart. Here’s a take on that crisp, this time a healthy strawberry rhubarb crisp made with maple and a pure oat topping. It’s naturally sweet, naturally gluten free, and most importantly naturally SO darn good. Keep reading for our strawberry rhubarb crisp recipe!

As you may know, Alex and I love healthy desserts. However, our philosophy around healthy has changed over the years, because here’s the thing: desserts need to taste good! Otherwise they’re not a treat. This strawberry rhubarb crisp has just a tinge of healthy, but most of all it tastes really, really good. Here’s what we’ve done to revamp this into a whole-food centric, but still delicious, dessert recipe:

  • The crisp topping is oats and oat flour. No flour here, meaning that it’s naturally gluten free if you use gluten free oats.
  • There’s no refined sugar: it’s all maple! We love using maple syrup as a natural sweetener in our desserts. Be aware that all sweeteners are sugar, so it’s still not a health food. But we love the nuanced sweetness that maple brings.
  • It’s got just enough sweetness. Some strawberry rhubarb crisp recipes call for boat-loads of sugar: for this one, we’ve used just enough! But don’t worry — it still tastes very sweet! We’ve used more strawberries than rhubarb to help rely on the natural sweetness of the berries to balance out the tart rhubarb.

For our crumble topping, we’ve used butter, but as a vegan option you can use coconut oil. So, we’ve got a lot of bases covered for all sorts of eaters. Most of all, we hope that this crumble recipe will make you nostalgic to childhood, if you grew up eating rhubarb too! There’s something magical about this weed-like plant: it’s one of the best sweet treats, if you ask us!

How to store leftovers

Does crisp need to be refrigerated? You can leave out your strawberry rhubarb crisp on the counter for up to 1 day (covered, at night). This way, the crumbly topping can stay crisp. After 1 day stored at room temperature, we’d refrigerate any leftovers. Let us know if you try this strawberry rhubarb crisp: it’s a keeper in our book!

This strawberry rhubarb crisp is sweet tart and nostalgic, sweetened with maple syrup with a crumbly topping of pure oats.



  • 2 cups chopped rhubarb (10 ounces)
  • 3 cups sliced strawberries (1 pound)
  • 3/4 cup pure maple syrup, divided
  • 2 tablespoons cornstarch
  • 1 tablespoon vanilla
  • 1 cup old fashioned oats
  • 3/4 cup oat flour OR 3/4 cup oats ground finely in a food processor or high speed blender
  • 1/2 teaspoon cinnamon
  • 1/4 teaspoon kosher salt
  • 5 tablespoons butter or coconut oil
  • Add-in ideas: 1 teaspoon orange or lemon zest or 1 tablespoon finely minced fresh ginger root in the filling adds complexity; 1/4 teaspoon ground cardamom in the crumble would also be nice


  1. Preheat the oven to 350 degrees Fahrenheit.
  2. Make the filling: Chop the rhubarb into small pieces (about 1/2 inch wide). Slice the strawberries, cutting any large strawberry slices in half. In a medium bowl, mix the strawberries and rhubarb with 6 tablespoons maple syrup, the corn starch and the vanilla.
  3. Make the topping: If necessary, process your oats into oat flour in a food processor or high speed blender (should take only a minute or so!). In a medium bowl, mix together the oats, oat flour, cinnamon, and kosher salt. Cut the butter into small pieces and then use your hands to mix it into the oats until fully distributed and a crumbly dough forms. (If using coconut oil, it can be room temperature; use the same method to add it.) Stir in the remaining 6 tablespoons of maple syrup.
  4. Pour the filling into a round 9-inch pie pan (or 9 x 9 inch pan). Pour the crumble on top and smooth it into an even layer with your fingers.
  5. Bake for 45 to 50 minutes until the top is evenly lightly browned and the filling is bubbly. Cool for a few minutes, then serve warm. You can leave out your strawberry rhubarb crisp on the counter for up to 1 day (covered, at night) so the crisp topping can stay crisp. After 1 day, refrigerate any leftovers.
