Ingredients
Method
- Preheat oven to 375°F. Lightly butter a 9x13 inch baking dish or an 8-inch square dish if you prefer a taller crumble.
- Prepare the filling: In a large bowl, combine the sliced strawberries with granulated sugar and let them sit for about 10 minutes while the oven preheats and you work on the topping. This draws out some of their natural juices.
- Add cornstarch, lemon juice, vanilla extract, and salt to the berries. Stir gently but thoroughly — you want every piece coated. The mixture will look watery at first; that's normal since the cornstarch will thicken it as it bakes.
- Make the topping: In a separate bowl, whisk together flour, sugars, and salt. Add the cold butter cubes and work them into the dry ingredients using your fingers or a pastry cutter until you have a coarse, sandy texture with some pea-sized lumps of butter remaining. These butter bits are what create flaky pockets in the finished crumble.
- Sprinkle chopped pistachios over the flour mixture and stir to distribute evenly.
- Pour the berry mixture into your prepared baking dish. Scatter the topping evenly across the top — don't press it down, just let it rest loosely on the fruit.
- Bake for 40-45 minutes until the topping is golden brown and you can see bubbles of berry juice working their way to the surface around the edges. If your topping browns too quickly after about 25 minutes, tent a piece of foil over it loosely.
- Let cool for at least 15 minutes before serving — this is important because the filling needs time to set up, or you'll get runny fruit everywhere when you scoop.

Notes
I keep it in my regular rotation now because it doesn't demand anything special: no fancy ingredients, no complicated technique. The trick is letting the butter get properly cold before you cut it into the flour and nuts. I learned this after one attempt where I used room-temperature butter and ended up with a soggy mess instead of that shaggy texture I was looking for.
I serve it warm, often straight from the dish with nothing more than a spoon or a small scoop of vanilla ice cream on top. It travels well too — I've taken it to potlucks where people always ask what's in the topping.
