Strawberry Rhubarb Crisp
This vegan strawberry rhubarb crisp is super easy to make in under an hour and absolutely perfect for Summer!
- vegan and can be gluten-free – works for those with dietary restrictions!
- freezes well – bake in advance and freeze for a delicious dessert ready for you at any time
- adjustable – swap out the fruits for other berries, apple or stone fruits
- extra-thick topping – we all know the topping is the best part, right?
Quick Note: While absolutely delicious, this is not my healthiest crisp recipe. It uses a cup of sugar and half a cup of butter. For lighter versions, try my oil-free blueberry crisp or grain-free vegan apple crisp.
Ingredients You’ll Need
- strawberries – fresh strawberries are best here
- rhubarb – rhubarb is the star of this recipe! Pick some from your garden or find it in stores during the Summer months.
- flour – use all-purpose flour, whole-wheat flour, spelt flour or a gluten-free flour blend
- rolled oats – rolled, old fashioned or large flake oats are best
- vegan butter – vegan butter works best in this recipe but it can be subbed with coconut oil if that’s all you have
- sugar – for a refined sugar-free recipe, use coconut sugar, otherwise any dry granulated sweetened works
- cornstarch – cornstarch thickens the rhubarb filling, it can be subbed with arrowroot powder if needed
- chia seeds – optional but they help thicken up the strawberry filling, which can be on the runny side without them
Step by Step Instructions
Step 1. Make the filling by roughly chopping the strawberries and rhubard and adding to your baking dish. Add the cornstarch and sugar and mix until everything is coated. If you’re using the chia seeds, add them as well.
Step 2. Make the crisp topping by adding the ingredients to a bowl and using your hands or a pasty cutter to combine into a crumbly mixture.
Step 3. Add the topping mixture over top of the fruit in the baking dish and use your hands to spread and gently press down.
Bake for 45 minutes then let cool for 15 before serving warm with your favorite vanilla ice cream.
Recipe Tips and Notes
- You can use all rhubarb if you prefer. No need for chia seeds if you’re using all rhubarb.
- Rhubarb can be swapped for apple.
- Strawberries can be swapped for peaches, raspberries, blueberries, cherries, or a combo of any of these, up to 2 cups.
- The all-purpose flour can be subbed with spelt flour, whole-wheat flour or a gluten-free flour blend such as Bob’s Red Mill. I have not tested this recipe with oat flour, almond flour or coconut flour, although oat flour or almond flour should work.
Do I have to use chia seeds?
No. The crisp will still be delicious without them, however, strawberries release a lot of moisture when cooked, which can make the crisp filling quite mushy.
Chia seeds, much like in this blueberry chia jam, help to absorb the excess moisture from the strawberries and thicken the filling. They’re optional but they help make the filling thick and jammy rather than soupy.
Can I use frozen fruit?
I prefer fresh fruit in crisps and crumbles but frozen will work if needed. There’s nothing special you need to do if using frozen fruit, just proceed with the recipe as written using frozen instead of fresh fruit.

For the Strawberry Rhubarb Filling
- 2 cups (300 g) quartered fresh strawberries
- 3 cups (450 g) chopped fresh rhubarb
- 1 tbsp cane sugar or coconut sugar
- 1 tbsp cornstarch
- 2 tbsp chia seeds, optional, see notes
For the Oat Crisp Topping
- 1 cup (100 g) rolled oats
- 1 cup (120 g) whole wheat or all-purpose flour
- 1 cup (215 g) organic cane or coconut sugar
- 1/2 cup (110 g) vegan butter
- 1/4 tsp salt, optional
- Preheat the oven to 350 F.
- Cut the strawberries into quarters and the rhubarb into roughly 1/4 inch pieces. Add the chopped fruit to a 7-9 inch baking dish.
- Add the sugar, cornstarch and chia seeds, if using, to the fruit and mix well until all the fruit is coated.
- Add the oat crisp ingredients to a bowl and use your hands or a pastry cutter to mix well until it forms a uniform, crumbly mixture and all the flour is wetted. Alternatively, add the ingredients to a food processor and pulse a few times to combine.
- Evenly spread the oat mixture over the fruit in the baking dish. Gently press it down over the fruit.
- Bake for 45 minutes then let cool for 15 minutes before serving. Serve warm topped with coconut whipped cream or your favorite vanilla ice cream.
This crisp has quite a thick topping but it’s how my mom always made apple crisp and it’s my favorite. You can reduce the topping by as much as half to lighten up the recipe.
I’ve made this recipe with vegan butter and coconut oil and much prefer butter. The result with butter is firmer and crispier. You can, however, sub coconut oil if needed. If you’re not vegan, you can use regular butter.
You can use a 7-9 inch square, round or oval glass, metal or ceramic baking dish.
To store leftovers, let cool completely then cover and store in the fridge for up to 5 days. Reheat in the oven or microwave until warmed to your preference.
To make in advance and freeze, let cool completely after baking, then cover well with foil and freeze up to 3 months. When ready to enjoy, thaw overnight in the fridge then heat in the oven for about 20 minutes until heated through. It can be heated from frozen in a pinch, it will just take longer.
Strawberries release a lot of moisture when cooked so strawberry crisp is mushier than say, apple crisp. Using chia seeds helps to absorb some of that moisture and thicken the filling. They’re optional but help make the filling thick and jammy rather than soupy!
