This easy Strawberry Crumble recipe (also known as a strawberry crisp!) is the first thing I make the moment I spot fresh strawberries at the farmer’s market. One baking dish, ten minutes of actual work, then the oven takes over. Serve it warm with vanilla ice cream and, fair warning, it won’t last until morning.
My Grandmother Made It, My Mom Made It, and It Even Won Over My Chocolate-Obsessed Husband
Growing up, we were a fruit dessert family through and through. My mom made them, my grandmother made them; fruit pies, crisps, cobblers, pies. It was just what you made when fruit was in season. Then I married Brad. The man is chocolate, chocolate, and oh yeah, more chocolate and for years our kids were firmly in his camp. Now that they’ve flown the nest? I’m making my fruit desserts again, and nobody’s stopping me. Brad is even coming around. Slowly, but he’s coming. There’s something about warm, jammy fruit bubbling under a buttery crisp topping that eventually wins everyone over. My Blueberry Crumble Cake is what started softening him up, if I’m being honest.
This is the strawberry version I’ve landed on after years of tweaking, the crumble topping ratio, fresh vs. frozen, exactly how long to bake it so the filling actually sets. What’s below works every single time. I’ll walk you through everything for this easy recipe, plus all the ways you can make it your own.
Already swimming in strawberries? You’ll also love my Old Fashioned Strawberry Shortcake, these Strawberry Brownies (yes, they’re as good as they sound), and Strawberry Freezer Jam for saving that peak-season flavor. Or try my peach cobbler! All summer staples!
What You Will Love About this Strawberry Oat Crumble
- It’s genuinely fast. I know every recipe on the internet claims this, but I mean it — the hands-on time here is maybe ten minutes, and then the oven does the rest. It doesn’t look like a ten-minute dessert, which is the whole point.
- Fresh or frozen both work. Got a bag of frozen strawberries in the back of your freezer right now? Thaw them, drain them, you’re in business.
- The crumble topping is the whole thing. Golden, buttery, oat-y – it shatters just enough when you scoop it, stays crisp on top while the berries bubble underneath. I have yet to see anyone stop at one serving. Consider yourself warned.
- Two bowls and a baking dish, that’s your whole dish situation. Nothing fancy, nothing you don’t already own.
- Easy to adapt. Gluten-free, dairy-free, sugar-free – I’ve tested all the swaps and they hold up. Details are below.
- If you have enjoyed an apple crumble (aka apple crisp) you are going to love this!
Strawberry Crumble Recipe Ingredients
Strawberry Filling
- Fresh Strawberries: I like fresh, juicy strawberries here. Hull them and cut into slices or quarters so they cook evenly.
- Cornstarch: Your thickening agent. It binds with the strawberry juices as they heat up, turning them from watery to jammy strawberries. Don’t skip it.
- Granulated Sugar: For a hint of extra sweetness. If your berries are on the tarter side, add a little more.
- Orange Juice: The citrus brightens all that strawberry flavor. Water works in a pinch.
- Vanilla Extract: Just a teaspoon stirred right into the strawberry filling — it rounds out the flavor and adds a little warmth.
Crumble Topping
- Old-Fashioned Oats: Old-fashioned rolled oats give you that hearty, slightly chewy texture. Do not use quick oats; they go mushy and won’t give you the clusters you’re after.
- All-Purpose Flour: Helps bind the topping together and gives it a little more structure. Gluten-free all-purpose flour works just as well.
- Light Brown Sugar: Adds sweetness and makes the topping taste extra rich and buttery.
- Ground Cinnamon: A gentle warmth that plays beautifully with the strawberries.
- Salt: Always add salt to your sweets. It balances the sweetness and makes every other flavor pop.
- Butter: Melted or very soft. This is what holds the crumble together and gives it that golden, slightly crispy finish.
- Vanilla Extract: Stir it right into the melted butter before adding to the oat mixture.

How to Make Strawberry Crumble
Step 1 | Make the Crumble Topping
Whisk together the oats, flour, brown sugar, cinnamon, and salt in a medium bowl. Stir the vanilla into 6 tablespoons of melted butter, then pour it over the oat mixture. Stir until the butter coats everything evenly.
Squeeze a handful; if it holds together, you’re good. If it crumbles apart, add butter one tablespoon at a time until it holds. Pop the bowl in the freezer while you prep the filling.
Step 2 | Prep the Strawberry Filling
Add your sliced strawberries to a large bowl and toss with the cornstarch until coated. Add the sugar, orange juice, and vanilla and stir to combine. Pour the filling into your prepared baking dish.
Step 3 | Assemble and Bake
Break apart the crumble topping and scatter it evenly over the strawberries. Don’t press it down – you want those loose, craggy pieces that get nice and golden. Bake at 350°F for 30–40 minutes, until the topping is deeply golden and the strawberry juices are bubbling up around the sides.
Step 4 | Cool Before Serving
This is the hardest step! Let the crumble rest for 10 to 15 minutes before serving. This gives the filling time to set so it’s not completely runny when you scoop it. Serve warm as-is, or top with a big scoop of vanilla ice cream or a dollop of homemade whipped cream, or coconut whip if you’re keeping it dairy-free.”
Easy Strawberry Crumble Top Tips
- Don’t pull it out of the oven until you see the juices bubbling. The bubbling is your cue that the filling has fully thickened. Pull it too soon, and you’ll have watery filling under that beautiful topping – no matter how golden the top looks. The longer it bakes, the jammier and more concentrated those strawberry juices become. If you feel like it’s browning too quickly, loosely lay a piece of foil over the top.
- Use the juiciest strawberries you can find, but know it affects the outcome. Very juicy berries mean a thinner, more saucy filling, while less juicy berries produce something thicker and jammier. Both versions are delicious and work just fine for this easy strawberry crumble recipe.
- Not enough butter in the topping is the most common mistake. If you skipped the squeeze test in Step 1 and your topping looks sandy or dusty on top of the fruit instead of forming golden clumps, that’s why. The fix is simple, pull it out, drizzle a little more melted butter over the top, and keep baking.
Strawberry Oat Crumble Variations & Substitutions
- If your strawberries aren’t super sweet, add up to ½ cup of sugar.
- If using frozen strawberries, thaw and drain them before using.
- Add different fruits: Throw in fresh raspberries, blackberries, or blueberries for a mixed berry crumble. Total fruit should equal about 2 pounds.
- Add nuts: I almost always toss a handful of chopped pecans into the crumble topping, because more crunch! Walnuts or sliced almonds work beautifully too.
- Sugar-Free: Swap the sugar for a good monk fruit/allulose blend.
- Brighten the filling: Add 2 tablespoons of fresh lemon juice and/or 1 teaspoon of lemon zest in place of the orange juice. Orange zest also works beautifully for a slightly sweeter, more floral citrus note.
- Gluten-Free: Make sure your oats are GF-certified and swap the flour for a good cup-for-cup gluten-free flour. You could also try using half GF Flour and half oat flour, adds moisture and nuttiness.
- Dairy-Free: Use coconut oil or a dairy-free butter. Miyoko’s and Earth Balance both work well.
- Cornstarch Substitute: Arrowroot or tapioca flour works at a 1:1 swap. Note that arrowroot can get slightly slimy if overcooked, and tapioca gives a slightly chewier, glossier finish to the filling.
- Individual Ramekins: Divide the filling and topping evenly among 6 to 8 ramekins for single-serve portions. Bake at the same temperature, but check a few minutes earlier.
Making for Two: Use the serving slider in the recipe card to scale down, or cut every ingredient in half and bake in a smaller dish. Or split it even further into individual ramekins — bake, cool, cover well, and freeze. You can warm them straight from frozen, just make sure your ramekins can go from freezer to oven, and pull them out while the oven preheats.
Want to Make a Strawberry Rhubarb Crumble?
Honestly, this might be my favorite version. The rhubarb brings a bright, tart backbone that makes the strawberries taste even better; it’s one of those combinations that’s been around forever because it just works. Check out my strawberry rhubarb crisp; fruit crisps are the best!
Pro tip: If your rhubarb stalks are very thick, cut them in half lengthwise before chopping so everything cooks evenly.

Strawberry Crumble Storage and Make Ahead Tips
- Storage: Store leftover crumble covered or in an airtight container at room temperature for up to 2 days, or in the fridge for up to 5 days. The topping will soften over time in the refrigerator; that’s normal.
- Freezing: Allow the crumble to cool completely, then cover tightly or transfer to a freezer-safe container. Freeze for up to 3 months. You can also freeze the unbaked crumble topping separately in a zip-top bag for a quick assembly later.
- Reheating: Reheat individual portions in the microwave for 30–60 seconds, or reheat the whole dish in a 350°F oven for 15–20 minutes until warmed through. The oven will help crisp the topping back up — worth the extra few minutes.
- Make-Ahead: The crumble topping can be made ahead and stored covered in the refrigerator overnight. Cut your strawberries ahead of time if you like, but do not combine them with the sugar, cornstarch, and juice until you’re ready to assemble and bake. If the strawberries sit with the sugar too long, they’ll start releasing their juices before baking, and you want to save that magic for the oven.
Strawberry Crumble FAQs
The topping. You need enough butter so the oat mixture holds together when you squeeze it, that’s what gives you those satisfying golden clusters instead of a sandy, dusty layer. The other thing is baking it long enough that the fruit juices are actually bubbling up around the sides. That’s how you know the filling has fully thickened and your crumble won’t be watery underneath.
What’s the difference between a strawberry crisp and a strawberry crumble?
Technically, a crisp has oats in the topping and a crumble doesn’t, it’s just flour, butter, and sugar rubbed into a sandy streusel. But honestly, the terms get used interchangeably all the time, and this recipe sits right on that line. Call it what you want, it’s delicious either way.
A crumble has a streusel-style topping made from oats, flour, butter, and sugar, it bakes up loose, crunchy, and clustery. A cobbler uses a drop-biscuit or poured batter topping instead, which bakes up softer and more cake-like. Both are wonderful; they just scratch a different itch. If you want to go the cobbler route, my Old Fashioned Blueberry Cobbler is a great place to start, and the technique works beautifully with strawberries, too.
Not enough butter is the biggest one — the topping turns to dust instead of forming crispy golden clumps. The second is pulling it from the oven too early. If you don’t see the juices bubbling up around the edges, it needs more time, no matter how golden the top looks.
Yes! Strawberries that are a little past their prime, slightly soft, or starting to wrinkle are actually perfect for baking. Any texture issues disappear entirely once they’re bubbling away under the crumble topping.

Equipment
Ingredients
Crumble Topping:
- 1 cup old-fashioned oats quick cooking won't set up the same in the crisp, may be used, just might be softer
- ⅔ cup all-purpose flour or gluten-free AP flour cup for cup
- ⅔ cup light brown sugar packed
- ½ teaspoon ground cinnamon
- ½ teaspoon kosher salt
- 6 – 8 tablespoons salted butter melted or really soft, if using unsalted butter decrease salt by ¼ teaspoon
- 1 teaspoon vanilla extract or vanilla bean paste
Strawberry Filling:
- 2 pounds fresh strawberries hulled and sliced or quarters (thawed, drained frozen works too, about 4 cups) see notes for adding rhubarb
- 3 tablespoons cornstarch see post to use other options
- ⅓ cup granulated sugar I like using organice cane sugar
- 2 tablespoons orange juice or water, but fresh juice is so much better,
- 1 teaspoon vanilla extract adds a little extra depth
Optional
- vanilla ice cream for topping said crumble
- homemade whipped cream
Instructions
- Preheat your oven to 350°F (175°C) and prepare a 9″ square baking pan with a little bit of spray oil. A 7×11 oval baking dish works well too.
- In a medium bowl add your oats, flour, brown sugar, cinnamon and salt and whisk together. Pour your vanilla into 6 tablespoons melted butter and stir a little until mixed in. Pour the wet ingredients over the oat mixture and stir everything together until the butter coats everything. Squeeze a handful of oats in your hand and see if it sticks together. If it doesn't hold together, add another tablespoon of butter. Add butter a tablespoon at a time until your oat mixture holds together when squeezed. Place in freezer until ready to assemble.1 cup old-fashioned oats, ⅔ cup all-purpose flour , ⅔ cup light brown sugar, ½ teaspoon ground cinnamon, ½ teaspoon kosher salt, 6 – 8 tablespoons salted butter, 1 teaspoon vanilla extract
- In a large bowl, add your sliced strawberries and cornstarch and toss with a spoon to coat them. Add sugar, vanilla extract and orange juice and stir with your spoon to make sure all the strawberries are coated. Pour your strawberries into prepared baking dish.2 pounds fresh strawberries, 3 tablespoons cornstarch, ⅓ cup granulated sugar, 2 tablespoons orange juice, 1 teaspoon vanilla extract
- Break apart the crumble mixture to top the strawberries. Place baking pan into the oven and bake for 30-40 minutes. When your crumble is golden brown and the strawberries are bubbling through on the sides it's done. Remove from the oven and allow to cool for 10-15 minutes so the filling can set before serving. Serve warm plain, with whipped cream or ice cream. Enjoy!!
- It's important to make sure to wait until the juices are bubbling up from the sides. If not, you will have watery cobbler under the crumble topping. The longer you bake it the jammier it will get. But even if it's runny, it's still delicious. The juiciness of your strawberries will determine the overall outcome of the crumble. Place a scoop of vanilla ice cream on top or slather with homemade whipped cream, and nobody will care!vanilla ice cream, homemade whipped cream
