Gluten free strawberry rhubarb crisp is the perfect dessert for all of your summer gatherings! Tart rhubarb mixes with sweet strawberries and a buttery crumble topping for a delicious dessert.

Okay, I’m just going to put this out there – this strawberry rhubarb crisp may very well be my favorite dessert we’ve ever made. Yep, I like it even more than our s’mores bars and no-bake cheesecake bars! Berry crisps have long been one of my go-to last-minute gluten free desserts. They’re easy to make, take advantage of the abundance of in-season fruit, and are always a crowd-pleaser.

This strawberry rhubarb crisp takes it up a notch higher. I love all things tart, so the bit of sourness from the rhubarb mixed with the sweetness of in-season strawberries is a perfect balance that’s slightly different from your typical crisp. Add to that a buttery topping that is somewhere between a crisp and a cobbler (or maybe a crumble?), some vanilla ice cream, and you’ve got a combination that just screams summertime.

The ingredients for this yummy dessert are quite simple! Below, you’ll find everything you’ll need, along with any applicable notes/swaps. Find full ingredient amounts in the recipe card.

How to Make Strawberry Rhubarb Crisp

Making this gluten free strawberry rhubarb crisp only requires a few simple steps:

The filling for a strawberry rhubarb crisp in a large dish.

The crumble for strawberry rhubarb crisp in a large glass bowl.

  1. Chop up your rhubarb and strawberries.
  2. Add the fruit to a saucepan with the lemon and coconut sugar, and let it cook for about 10 minutes. This will allow the rhubarb to break down.
  3. While the fruit is cooking, it is time to make the topping! You’ll add the gluten free flour, sugar, salt, butter, and pecans to a bowl, and mix them all together until a crumbly mixture forms.
  4. After the fruit has cooked down, the mixture may look a little bit thin and soupy – but that’s ok! Just whisk some arrowroot starch with water, then stir it into the rhubarb mixture and bring it to a boil quickly until it thickens. If you feel it is still not thick enough – add more arrowroot.
  5. Finally, you’ll add the fruit mixture to an 8×8 pan, put the crumble mixture on top, and bake for 30 minutes! Then you’re ready to serve it up with some vanilla ice cream.

Frequently Asked Questions

What is rhubarb?

Rhubarb looks kind of like pink celery, but tastes nothing like it! While it is technically a vegetable, it is commonly classified as a fruit because it is typically used in jams, jellies, and desserts like this one. Rhubarb is typically tart, similar to a green apple, but sweetens slightly when cooked. It is great in desserts, made into a syrup for cocktails and mocktails, or you can try pickling it for use in more savory dishes.

Can I use frozen strawberries and rhubarb for the crisp?

You can – we actually used frozen rhubarb for ours and it turned out great!

Where can I find rhubarb?

You can find rhubarb in the produce section of your grocery store. It is in season from April through June, and when picking your rhubarb you’ll want to look for thinner, pink stalks for the best flavor. If you can’t find rhubarb in the produce section, check the freezer section! Many stores carry pre-cut rhubarb there.

Can I use a gluten-free flour for the crisp topping?

You can absolutely use gluten free flour for the topping! We used King Arthur’s GF all-purpose flour (we use it for everything!).

One of my other favorite things about this recipe is that it is very versatile! Rhubarb season runs through June, but you can easily replace it with any type of berry, or even peaches or plums. Whichever way you make it, we hope you love this strawberry rhubarb crisp!

    This crisp had the perfect sweet/tart ratio! I used fresh rhubarb and strawberries. My filling came out a little runny but thickened up as it cooked, and it kind of took over a good portion of the crisp part. However, that didn’t detract from the taste, which was really wonderful. Topped it with some whipped cream.

    I made this exactly as written and it was a hit! My in laws favorite pie is a fruit of the forest from a local market, made with rhubarb. I’ve tried to incorporate rhubarb in a few recipes with no success. I made this for dessert at Sunday family dinner. Everyone enjoyed it, ages 3 – 75! I’ll definitely make it again and use this as a go to with different fruit combos through the year. Thank you!

    1. Awesome, Meg! We’re so glad everyone loved this recipe! Thank you so much for taking the time to share this with us!

    The perfect summer dessert! Very simple to make, and came out absolutely delicious! I made it to take to a 4th of July gathering at the lake and it was a hit!

    1. Awesome, Kaelin! We’re so glad everyone loved it!

    This was tasty, but my attempt at this recipe didn’t look nearly as pretty as the photos on the website. Between using green rhubarb from my garden and the brown coconut sugar, my crisp had a brownish pink filling that was quite runny. The gluten-free topping also didn’t brown to a dark golden color as in the photo. Perhaps baking it in a glass pan, rather than metal, affected the color and consistency. Again, it tasted fine, but for all the work to pre-cook the filling, the presentation was rather disappointing. Next time I’ll try it without precooking the rhubarb and strawberries, and will try tapioca or something else as a thickener.

    1. I’m sorry this recipe didn’t work out as you hoped, Mary!

    I was so excited to make this for my GF sister and the whole family loved it! We used frozen rhubarb from her mother in law’s garden and fresh strawberries. Topped with vanilla ice cream and whipped cream. Will def make again this summer!

    This crisp turned out beautiful and yummy. It didn’t thicken enough and I would probably add a little honey to sweeten it just a little bit more.

    Get ready for a slew of comments as I have been only cooking from Fed & Fit recipes the last three weeks 🙂

    I’ve made this, only with strawberries, two weeks in a row. It’s such a traditional dish that I missed being gluten free. I added some almond flour to add a little more grit to my Bob’s 1-1 gluten free flour and my gluten-eating husband has loved it too.

    Thank you for another great one.

    1. Haha, we love it!! And we’re so glad you guys have enjoyed this recipe. It’s such a perfect summertime treat!

    I used ghee, but apparently it was too soft. The topping turned out like pie dough and ever got crisp:( Still tasted great! Very easy to make.
