Ingredients you’ll need (with substitutions)

One of the best parts about this homemade strawberry crumble recipe is that you only need a few simple ingredients to make it! Here is what you’ll need. 

• Strawberries – I recommend using fresh strawberries. You want to look for deep red, vibrant berries. If you need to use frozen then those will work as well. 
• Arrowroot starch – this is used to help thicken the strawberry filling. You could also use cornstarch. 
• Orange juice and zest – fresh orange juice and zest are recommended for the best flavor. You could also use lemon juice and zest. 
• Coconut sugar – is used to enhance the sweetness of the strawberry filling. You could also use white sugar or brown sugar. 
• Oats – are used to add texture to the crumble topping. Old-fashioned oats work best but rolled oats will also work fine. 
• Oat flour – I used organic oat flour but have also tested this recipe using gluten-free all-purpose flour and regular white flour and those worked great. The flour makes the cookie crumble topping more crumbly, which is so good. 
• Pecans or walnuts – add a nice nutty flavor and crunch to the topping. 
• Brown sugar – light brown sugar, just a bit adds the perfect hint of sweetness to the crumble topping. You could also use coconut sugar as well. 
• Butter – regular unsalted butter, or you can use plant-based butter for a vegan version of this recipe. Coconut oil will work as well. 
• Vanilla – real vanilla extract for that warm, cozy flavor that is great in any baked recipe. 
• Salt – just a pinch of salt is used to enhance the other flavors in the strawberry crumble.

How To Make This Homemade Strawberry Crumble

This fuss-free strawberry dessert is so easy to make in just a few simple steps. Here is a summary of how to make it.

Let the crumble cool for a few minutes then serve and enjoy!!!

Expert Tips For The Best Results

• You can make this easy strawberry crumble in a 9-inch pie dish, 8×8 pan, or cake pan. 
• Frozen fruit can be used in a pinch but fresh is always best in any crumble or crisp recipe. 
• Cut the strawberries in half for smaller strawberries and in quarters for larger ones. I like them in larger chunks but if you want to cut them smaller then go ahead. 
• To make your own oat flour, blend some oats in a blender or food processor. For ⅔ cup of oat flour, you will need to blend about ½ cup of oats. 
• Let the crumble cool. Once this strawberry crumble comes out of the oven, it will be very hot, so it is best to allow it to cool for 10 minutes before serving it. 

Serving Suggestions

Here are a few ways to serve this amazing no-fuss healthy summer treat!

• Top it with some vanilla ice cream.
• Add a dollop of whipped cream.
• Finish it with a scoop of vanilla yogurt and a sprig of mint.
• Add a drizzle of caramel or chocolate sauce.

Storing and Reheating Strawberry Crumble

Leftovers can be stored in an airtight container in the refrigerator and reheated in the oven at 350°F or in portions in the microwave until warmed through. Note: if you warm the crumble in the microwave then the topping may not become as crispy and may be slightly soggy. 

Frequently Asked Questions

Is strawberry crumble gluten-free?

Strawberry crumble is not usually gluten-free but this healthier version is fully gluten-free since we used oats + oat flour in place of the traditional white flour used in most crumble recipes. 

How do you keep crumble topping from getting soggy?

To prevent your crumble from getting soggy, make sure you use the correct ratio of flour, sugar, and butter. Using too much butter can result in a greasy, soggy topping, while insufficient oats and flour can affect the texture and crispiness.

Can you use frozen fruit in a homemade crumble?

While frozen fruit can be used in a crumble recipe, fresh fruit is recommended for the best, most delicious results.
