Gluten Free Strawberry Rhubarb Crumble

This Gluten Free Strawberry Rhubarb Crumble is the perfect way to take advantage of the short rhubarb season. This yummy dessert recipe is naturally sweetened, always gluten-free (but can be made AIP and grain free), can be made vegan, and is made with only 10 ingredients!

Why is rhubarb always paired with strawberry?

Rhubarb is quite tart, so the sweetness of strawberries really helps temper that tartness. Plus, they are both in season during the summer months. Or spring months if you are in the southern US.

What's the difference between a crumble and a crisp?

A crumble and a crisp are essentially the same thing. The difference is usually in where you’re located.

How can you thicken strawberry rhubarb filling for pies without cornstarch?

If you’re avoiding corn or grains, arrowroot starch or tapioca starch are good gluten free substitutes for cornstarch.

Can I make strawberry and rhubarb crumble dairy free or vegan?

Sure thing! The only dairy product used in this recipe is ghee which is lactose free. However, you can use coconut oil as a substitute to make the recipe completely dairy free and vegan.

How long does a fruit crumble last?

If you store it in an airtight container, then it will last 3-4 days in the refrigerator. 

Ingredients

For the filling:

• Tapioca Starch: Arrowroot Starch is a good substitute.
• Lemon
• Rhubarb: It can be fresh or frozen.
• Strawberries: It can be fresh or frozen.
• Honey

For the topping:

• Cassava Flour: Otto’s Cassava Flour is preferred.
• Salt
• Coconut: Make sure it’s unsweetened and shredded. However, coconut flakes are a good substitute.
• Gluten Free Oats: Unsweetened Shredded Coconut is a good grain free substitute.
• Honey: If you have concerns about honey being gluten free, check out this post.

How to Make Gluten Free Strawberry Rhubarb Crumble

1. Preheat the oven to 350 F. Whisk the tapioca starch with lemon juice to create a slurry then set aside.

2. Add the strawberries, rhubarb, and coconut sugar to the 9x13 pan. Stir to combine.

3. Next add the tapioca slurry into the strawberry rhubarb mixture and stir until combined.

4. In a large bowl, whisk together the flour, coconut sugar, salt, shredded coconut, and oats. Add the ghee to the flour mixture and combine using a fork or pastry cutter until crumbly.

5. Top the strawberry rhubarb with the flour mixture.

6. Bake for 1 hour at 350 F until top is slightly browned and the filling is bubbling. Let cool slightly before serving, with whipped cream or your favorite ice cream.

Storing your crumble

Make sure to store your strawberry rhubarb crisp in an airtight container in the refrigerator. You could potentially store it on the counter overnight, but I wouldn’t do that for more than one night. It will go bad much faster if not in the refrigerator.

Thoughts on the best gluten free Strawberry Rhubarb Crisp

• Coconut oil is a good dairy free and AIP substitute for ghee.
• If you’d like to make your own ghee, try this easy recipe.
• Butter can also be used instead of ghee, but it must be softened.
• If you’re grain free, unsweetened Shredded Coconut is a good substitute for gluten free oats.
• Bake in an 9x13 baking dish or other small casserole dish.
• Make sure to thoroughly mix the tapioca starch and water slurry. Make sure that it’s thoroughly mixed with the strawberry rhubarb. And then don’t let the crumble sit for long before placing it in the oven. The slurry could fall to the bottom of the pan and get gummy.
• Otto’s Cassava Flour is preferred.
• Organic Gemini Tigernut Flour is recommended.
