Gluten free strawberry rhubarb crisp is a healthier remake of the classic dessert for late spring into summer. It’s an easy keto friendly rhubarb recipe that doesn’t take much effort to prepare.
Although we did not grow any rhubarb this year, I’ve been craving some of the tart plant. So I picked some up at a local market along with some organic strawberries to use in an easy rhubarb crisp.
I thought about making a low carb pie, but wanted something that would be quick to make. Fruit crisps are so simple that it wasn’t difficult to come up with a recipe. It only took about ten minutes to prepare and less than a half hour to bake.
That’s why I came up with this easy gluten free strawberry rhubarb crisp recipe. It combines two of the best low carb fruits of summer into a delicious dessert that’s perfect for sharing.
How to make a strawberry rhubarb crisp
I just love the sweet and tart taste of strawberry rhubarb filling. The mixture is just strawberry and rhubarb with some low carb sweetener and a little xanthan gum added as a thickener.
The best part is that you can mix the filling right in the baking dish so you don't have to dirty an additional bowl. Unfortunately, you'll want to mix up the topping ingredients first before adding them to baking dish.
I topped off the filling for this easy strawberry rhubarb crisp with a pecan crumb mixture. The original recipe used oat fiber but it's tough to find gluten free oats. So I changed the recipe to use a blend of almond flour and coconut flour instead.
This crumb topping works well with any fruit filling. The topping would be perfect for a zucchini crisp or mock low carb apple pie. Really, any cooked low carb fruit mix can be topped off with this nutty mix.
Once assembled, you bake the crisp in a 350°F oven until the filling is bubbling and the topping has browned. So be sure to preheat the oven before starting the preparation steps.
Should the gluten free strawberry rhubarb crisp be refrigerated?
Since there’s no sugar added to this low carb fruit crisp, I keep it in the refrigerator. In fact, I chill all my keto friendly treats in the refrigerator. I even store my keto cookies in the fridge.
Can you freeze it?
If you don’t want to over-indulge, I’d recommend freezing any extra servings for later. You can even make a double or triple batch to have a good amount stashed away for any rhubarb cravings you may have.
Other Low Carb Rhubarb Recipes
Since the carbs in rhubarb are only about 6 grams per cup with over 2 grams of fiber, it's definitely a keto friendly ingredient. But what other things can you do with it? Check out the following gluten free low carb recipes for other ideas:
- Gluten Free Rhubarb Crumble
- Cinnamon Rhubarb Muffins
- Low Carb Strawberry Rhubarb Upside Down Cake
- Strawberry Rhubarb Mousse
- Berry Rhubarb Jam
I've been wanting to try the upside down cake by Simply So Healthy. Hopefully, I'll get a chance to test that one out this summer to share with family and friends.

Can I use my canned strawberry rhubarb pie filling in this recipe? If so how much would I need to use? I have it canned in pints.
One can may be a little short so you may want to use two.
Do you have any suggestions for a butter substitute for a vegan version. No margarine, please, but do you think coconut oil would work?
My favorite vegan butter sub is butter flavored coconut oil but regular coconut oil should work too.
When you offer a metric option then there would be no teaspoons or tablespoons. Good of you to offer the option, but do it right.
When I know the metric equivalent, I add it. If I don't, it stays the same. I do know that many on metric keep teaspoons and tablespoons for American recipes. When it's liquid, I could offer some standard ml measurements but for dry ingredients, it takes some time to weigh and it's not something I'm in the habit of doing.
Made this in individual serving ramekins. All I can say is perfection in a dish.
This was yummy. I added the nuts after I cut in the butter. It was easier to cut in the butter that way. The nuts gave it a nice crunch. will be making this again.
This recipe is the bomb, I loved it! Only suggestion I have is to double the recipe because you will want seconds????
The first thing I did was double the recipe...this was absolutely delicious....my family loved it....I have been keto for 1 month now.
I will certainly be making this again. I usually make a pie and did not feel deprived and loved the pecans ...it really made this dessert special. I have to say I added a touch of vanilla to my filling.
Hi! I’m allergic to nuts—do you think there’s another substitute I could try instead of pecans? Thanks!
You could try a mixture of seeds like sesame seeds and flax meal.
Tasted yummy but I didn't get any crumble. It was all very gooey with zero crunch.
Just made the strawberry-rhubarb crisp and I wondered if there was an error in the recipe for the topping. I expected a crispy crust and what I got was less than crispy. I was surprised by the minimal amount of almond and coconut flour for the topping. To get a more cake-like topping what would you recommend ? Thanks, other than that it was a tasty dessert ????
The crunch should come from the chopped pecans. You could add more flour if you'd like and mixing it in egg first will make it more cake-like.
how would I freeze this? Or is it not freezer friendly?
It can be frozen baked or unbaked and should last for at least 3 months or longer.

Tart/sweet yumminess. I mixed chopped almonds in with the pecans for a little extra crunch. My new favorite dessert. Thank you!
Wondering if teaspoons should be tablespoons for the flour?
It's supposed to equal 2 tablespoons total of flour which is why the 2 teaspoons and 4 teaspoons. But it would likely work with tablespoons if you like more topping.
You don’t say how many servings there are in this recipe.
It's at the very top of the recipe card: 4 servings
Wow! Thank you for such a wonderful recipe! It was absolutely delicious. The nut topping was excellent. Would highly recommend! Hurry up and grow, rhubarb! Hubby is waiting for the next batch.
Looks delicious and will definitely make it. Am a little confused by the carbs though. In the recipe it says net 5 carbs per serving, in the Nutrition Facts it shows net 3 carbs!? Which is it? ?Does it make a difference if you use the other flour substitutes rather than Oat Fiber, which I can't get here? Thank you and thank you for all your amazing recipes! Cheers! ☺
The 5 carbs is an old value calculated based on actual brands used. The 3 net carbs is generic. I'll fix the confusion.
Oh, my. It's delicious!
I made this today. It was beautiful. Thank you for this recipe. Will definitely make it again ??
I wish I could find rhubarb at this time of year. You are lucky to have it!
I miss rhubarb. Strawberry Rhubarb pie is my favorite but this is a good substitute and easier.
I love the pie as well, but didn't want to take the time to make a crust. This was a lot quicker to make and just as delicious.
