I have a thing for delicious seasonal fruit crisps. You might remember this Blackberry Crisp with a custard filling using wild blackberries we pick in our neighborhood.
This gluten-free strawberry rhubarb crisp has a pure fruit base and can easily be made dairy-free or vegan. If you have leftover fruit after making a batch, you’ll definitely want to make this Strawberry Rhubarb Jam.
Can I Prepare This Rhubarb Crisp Ahead of Time?
Yes! Prep and store the fruit and crisp topping separately. Drain off any excess liquid from the fruit and place in a baking dish, then top with the crumble, and bake when you’re ready.
How to Store Gluten-Free Crisp
If you actually have leftovers (unlikely), you can keep this rhubarb crumble recipe (covered) at room temperature for a day. After that, I would transfer it to the fridge. If your summer kitchen has a fruit fly problem (aholes with tiny wings), store it in the fridge immediately.
Pro tips/recipe notes
- You can grind oats in a food processor to make “oat flour” if you don’t have any other gluten-free flour on hand.
- If you’re not gluten-free, using all-purpose flour works great!
- You can also “cheat” and use some Sugared Strawberries or Strawberry Puree if you already have some on hand.
- Sub in coconut oil or your favorite non-dairy butter to make this dairy-free or vegan.
- To reheat, you can microwave individual portions, or reheat the whole batch in the oven at 200 degrees for 15 minutes.
- If using frozen fruit (related: how to freeze rhubarb and freezing strawberries), drain off the liquid when it defrosts.
