Berry crisps and cobblers have always been my go-to summer desserts. I love classics like blackberry cobbler, mixed berry crisp, and peach crisp, but this homemade strawberry crumble might just be my favorite!

It's so easy to make—just mix fresh or frozen strawberries with maple syrup and lemon juice, then top them with a buttery oatmeal crumble. In 10 minutes, it's ready for the oven!

The strawberries get warm and jammy, and the crisp topping turns golden and delicious. Just like my homemade strawberry crumble bars!

Serve it with a scoop of vanilla ice cream, and you've got the perfect summer treat. It also happens to be gluten-free and dairy-free, but you'd never know. I can't wait for you to try it!

How to make the strawberry crumble:

Homemade strawberry crumble is so easy to make. Preheat your oven, and let's get baking:

fresh strawberries in a bowl with lemon juice, cornstarch, and coconut sugar

If you washed your strawberries, make sure they're dry. Toss the strawberries, coconut sugar, lemon juice, lemon zest, vanilla, and starch in a bowl.

Spread the oat mixture evenly over the strawberries.

Bake for 32–42 minutes until the top is golden and the strawberries are bubbly. (I baked mine for about 40 minutes.)

Tip: Let the strawberry crumble cool for 10–15 minutes before digging in! I love serving mine with vanilla ice cream, but I've included other topping ideas you can try below. Enjoy!

Top Tips

Fresh or Frozen Strawberries: This recipe works with both, making it super flexible depending on what you have!
No Need to Defrost Frozen Strawberries: If you're using frozen strawberries, don't thaw them. Just coat them in lemon juice and starch, then toss them straight into the pan. Thawing them first can make the texture mushy.
Make Ahead: You can prep the crumble a day in advance. Just cover it with foil and refrigerate it until you're ready to bake. If you've already baked it, reheat it in the oven for 10-15 minutes before serving.

Substitutions & Variations

Walnuts: Try chopped almonds or pecans. If you're nut-free, just skip them!

Crispier Topping: For an extra crispy topping, add a few tablespoons of shredded coconut to the oat mixture.
Fresh Strawberries: Frozen strawberries work too—just don't thaw them!
Mix Up the Fruit: Feel free to swap the strawberries with blueberries, blackberries, or mixed berries.

Storage & Freezing

Storing: Enjoy the crumble within 3-5 hours of baking for the best taste. Leftovers can be stored in the fridge for up to 3 days in a sealed container or in the original baking dish covered with aluminum foil.

Reheating: Reheat the whole crumble in the oven for 10-15 minutes at 350°F for the best results. If you're heating a single serving, microwave it for 45-60 seconds in 15-second intervals to avoid burning the berries.

Freezing: You can freeze the baked crumble! Store it in a freezer-safe, airtight container for up to 6 months. When ready to enjoy, thaw it overnight in the fridge, or bake it straight from frozen at 350°F until warmed and bubbly.

Frequently Asked Questions

Are strawberry crumble and strawberry crisp the same thing?

While they're often used interchangeably, there's a slight difference between the two. Both have a sweetened fruit base (strawberries here) topped with a crumbly mixture. A crisp usually includes oats and may have nuts in the topping, while a crumble typically doesn't contain oats (though some variations do).

Can I use frozen strawberries?

Yes! You can use frozen strawberries. Just make sure not to thaw them before baking. Toss them straight from frozen into the filling mixture and add them to the baking dish.

Is this strawberry crumble vegan?

Yes, this strawberry crumble is completely vegan. There's no butter, milk, or any animal products in the recipe.

Is it healthy?

This strawberry crumble is an excellent option for a lighter dessert. It's made with simple, whole ingredients and is gluten-free, dairy-free, and vegan. The oats add fiber, and it's naturally sweetened with maple syrup and coconut sugar. The coconut oil in the topping replaces butter, making it a bit lighter, too. There are no fake sugars or ingredients in this recipe!

Can I double the recipe?

Yes, you can easily double this recipe. If you do, bake it in a larger 9" x 13" dish to accommodate the extra ingredients. Just be sure to adjust the baking time as needed, since it might take a bit longer to cook through.
