The Best Strawberry Crumble Recipe for Summer

Strawberry crumble is a warm, juicy summer pudding under a golden, buttery oat topping. Ready in under 15 minutes of prep and baked in just 30, it makes the most of ripe Irish strawberries with very little effort.

Strawberry crumble is one of the simplest ways to turn a punnet of ripe berries into a proper dessert. Sweet strawberries are coated in a little sugar and cornflour, then baked under a rubbed-in topping of oats, flour, butter and muscovado until the fruit bubbles and the top turns crisp.

The method needs no special skill, just cold butter and your fingertips, and the whole dish comes together in one bowl and one baking dish. It is cheap to make, easy to scale up for a crowd, and works just as well with frozen berries when fresh ones are out of season.

A Taste of Irish Summer

Strawberry Crumble is deeply connected to my beautiful Ireland’s seasonal rhythms. When Irish summer hits its sweet spot, the fields of Wexford farms burst with strawberries so tender and flavourful they need little more than a hint of sugar and heat. These berries are summer’s crown jewels, and nothing showcases them better than a warm crumble.

Wexford strawberries have earned their glorious reputation —they're grown in the sunny southeast, benefiting from the region’s gentle climate and rich soil. They’re smaller and softer than mass-produced varieties, but their flavour is intense, sweet, and fragrant. They make this Strawberry Crumble something truly special.

This dessert is often enjoyed at garden parties, picnics, or easy weekend dinners. You can dress it up for a dinner party or serve it casually with a dollop of cream on a rainy Sunday. It’s also a brilliant recipe to make with kids—let them help hull strawberries or mix the crumble. These are the small kitchen moments that grow into lifelong memories.

Ingredients for Strawberry Crumble

• Strawberries – the juicy base of the dish; ripe Irish strawberries bring the sweetest, most fragrant flavour.
• Cornflour – thickens the strawberry juices as they bake so the filling sets rather than runs.
• Sugar – draws moisture from the berries and helps form a glossy, syrupy sauce.
• Cold unsalted butter – rubbed into the dry mix to give the topping its crumbly, golden texture; freezing it first keeps the crumble light, not soft. I always reach for Irish Kerrygold here — even during our year in Texas, it was the one butter I'd always buy, thank you H-E-B!
• Oats – add a rustic, hearty crunch that sets a good crumble apart from a plain pastry top.
• Plain flour – binds the topping and gives it structure as it bakes.
• Muscovado sugar – dark, moist and toffee-rich; it adds depth and helps the top caramelise.
• Light brown sugar – brings a gentle sweetness and helps the topping crisp to a golden finish.
• Flaked almonds – optional, scattered on top to toast in the oven and add extra crunch.

I do suggest going just a little over budget for muscovado sugar. It has a rich brown colour, a naturally moist texture, and a deep, toffee-like flavour that simply transforms the crumble topping. I choose muscovado because it adds real depth and complexity, which contrasts beautifully with the bright sweetness of the strawberries. It also behaves wonderfully in baking, helping the topping caramelise while keeping a slightly chewy, satisfying bite — exactly what you want in a proper crumble.

How to Make Strawberry Crumble

This is an easy recipe that doesn’t require any special tools or technical skills. You can pull it together in under 15 minutes, and the oven will do the rest.

1. Step 1: Preheat your oven to 180°C (350°F). Rinse the strawberries and remove the leafy tops. Halve the larger berries and leave the smaller ones whole, then place them in a deep baking dish. Sprinkle the sugar and cornflour evenly over the fruit and stir gently so every strawberry is coated.

2. Step 2: In a large mixing bowl, combine the oats, plain flour, muscovado sugar and light brown sugar. Take the cold, diced butter straight from the freezer and rub it into the dry mix with your fingertips, or a mixer, until it looks like coarse, oat-flecked crumbs. The cold butter is what keeps the topping crumbly rather than soft.

3. Step 3: Spoon the crumble mixture over the strawberries. Spread it out evenly and press it gently into the edges of the dish to seal in the fruit.

4. Step 4: Scatter the flaked almonds over the top. Set the dish on a baking tray and bake for 30 minutes, until the topping is golden and the strawberry juices are bubbling up at the sides.

How to Serve and Store Strawberry Crumble

Serve your strawberry crumble warm, while the fruit is still bubbling and the top is crisp. A scoop of vanilla ice cream or a dollop of whipped cream is the classic match, but my favourite is a quick stable cream made from equal parts double cream and cream cheese with a teaspoon or two of icing sugar whisked through. It holds its shape and balances the sweet, jammy fruit. For a grown-up version, a glass of prosecco alongside never goes amiss.

To store, cover and refrigerate any leftover strawberry crumble for up to 3 days, then reheat in the oven to bring the crunch back to the top. You can also freeze it unbaked for up to a month: assemble it in the dish, freeze, and bake straight from frozen with an extra 10 minutes or so. Any spare crumble topping is well worth saving for baked apples or pears.

How Much Does a Strawberry Crumble Cost to Make?

This is a genuinely budget-friendly dessert, and the strawberries are the only real expense.

• In Ireland, an 600g batch of strawberries runs to roughly €7-8 in summer (Keelings and Dunnes punnets are about €6.99 each), with store-cupboard oats, flour and sugar adding maybe €1, so the whole dish lands around €11–12, or about €1.80–2 per serving across six.
• In the UK, 800g of Tesco strawberries is around £5.50 (400g punnets at roughly £2.75), bringing the whole crumble to about £6.50, or just over £1 a serving — look for British berries in season at Tesco, Lidl or Aldi.
• In the USA, strawberries cost around $3.50–4 per pound, so 800g (about 1.75 lb) is roughly $7, with the finished dish near $8, or about $1.30 per serving; buy them at Trader Joe's, Costco or your local farmers' market.
• In Australia, a 250g punnet is about AUD $3–4, putting 800g near AUD $11 and the whole crumble around AUD $12, or $2 per serving, with Coles and Woolworths your easiest options.
• In Spain, a major strawberry grower, the fruit is cheapest of all at roughly €2–3 per kilo in season, so the entire dish can come in under €4, or well under €1 per serving, with Mercadona and local markets the place to shop.

Tips and Notes for the Best Strawberry Crumble

• Always taste your strawberries before adding the sugar. Ripe summer berries, especially Irish ones at their peak, are often sweet enough that they need very little help. If yours are tart or slightly underripe, add the full amount; if they are already sweet and fragrant, hold back a little so the dish does not turn cloying. The sugar is there to balance and draw out juice, not to mask the fruit.
• Freeze your butter before you start, not just chill it. Cold butter is the single biggest factor in a crumbly, light topping rather than a dense, greasy one. When the butter stays firm as you rub it in, it leaves small pockets that crisp up in the oven. If it softens too much, the mixture clumps into a paste and bakes flat, so keep it cold right up to the moment it goes in.
• Resist the urge to over-rub the topping. You want coarse, uneven crumbs with some larger lumps left in, not a fine, even sand. Those bigger pieces give the finished crumble its texture and crunch. Stop rubbing the moment the mixture holds together when pressed but still falls apart easily, and you will get the best contrast against the soft fruit.
• Do not skip the cornflour, even if it feels like a small detail. Strawberries release a lot of liquid as they bake, far more than firmer fruits like apples. Without something to thicken those juices, you end up with a watery dish and a soggy base. The cornflour sets the juices into a glossy, spoonable sauce that clings to the fruit instead of pooling.
• Use a deep baking dish rather than a shallow one. Strawberries collapse and reduce significantly in the oven, so a shallow dish can leave you with a thin layer of fruit and too much topping. A deeper dish holds a proper layer of berries and lets the juices bubble up around the edges without overflowing. It also gives you that satisfying ratio of fruit to crumble in every spoonful.
• Press the topping gently into the edges of the dish before baking. Sealing the crumble against the sides helps trap the fruit and its juices underneath, so the berries steam and soften properly. It also stops the juices from escaping and burning onto the dish. A light press is all you need; you are not packing it down, just closing the gaps.
• Add the flaked almonds at the same time as the topping, not partway through. They need the full bake to toast to a deep golden colour and develop their nutty flavour. Scattered on top from the start, they crisp alongside the crumble and add a lovely crunch. If you find they brown too quickly in your oven, loosely cover the dish with foil for the last ten minutes.
• Let the crumble rest for ten minutes after it comes out of the oven. Straight from the oven the fruit filling is molten and the juices are still loose. A short rest lets the cornflour-thickened sauce settle and firm up slightly, so it holds together when you spoon it out. It also saves you a burnt tongue, which is no small thing with hot strawberry filling.

Prep Time 15 minutes

Cook Time 30 minutes

Total Time 45 minutes

Ingredients

• 800g (28 oz) strawberries
• 800g (28 oz) strawberries
• 2 tablespoon cornflour
• 2 tablespoon cornflour
• 2 tablespoon sugar
• 2 tablespoon sugar
• 90g (3¼ oz) cold unsalted butter, diced
• 90g (3¼ oz) cold unsalted butter, diced
• 60g (⅔ cup) oats
• 60g (⅔ cup) oats
• 100g (¾ cup) plain flour
• 100g (¾ cup) plain flour
• 50g (¼ cup) muscovado sugar

• 50g (¼ cup) light brown sugar
• 50g (¼ cup) light brown sugar
• Handful of flaked almonds (optional)
• Handful of flaked almonds (optional)

Instructions

1. Preheat the oven to 180°C (350°F). Rinse and hull the strawberries, halving the larger ones and leaving the smaller ones whole. Place them in a deep baking dish, sprinkle over the sugar and cornflour, and stir gently to coat all the fruit evenly.
2. In a separate large bowl, combine the oats, plain flour, muscovado sugar and light brown sugar. Add the cold diced butter and rub it in with your fingertips until the mixture resembles coarse crumbs.
3. Spoon the crumble topping evenly over the strawberries, pressing it lightly into the edges of the dish to seal in the fruit.
4. Scatter the flaked almonds over the top. Set the dish on a baking tray and bake for 30 minutes, until the topping is golden and the strawberry juices are bubbling at the sides. Let it rest for 10 minutes before serving.

Notes

Use cold butter straight from the freezer for the crumbliest, lightest topping; softened butter bakes flat and greasy.

Do not skip the cornflour, as it thickens the juicy strawberry filling and stops the base turning watery.

Always set the dish on a baking tray to catch any juices that bubble over during baking.

Taste your strawberries first and adjust the sugar over the fruit to suit how sweet they are.

Spare crumble topping freezes well and can be used straight from frozen on baked apples or pears.
