Add the cold cubed butter to the flour mixture. Using your fingertips, work the butter into the dry ingredients until the mixture resembles coarse, crumbly pebbles with some larger oat flakes remaining.

Let the crumble rest for 10 minutes before serving warm. It pairs beautifully with a cold spoonful of heavy cream or vanilla ice cream.

Safety & Storage
High Risk Population
Walnut allergen warning: This recipe contains tree nuts. Do not serve to individuals with walnut or tree nut allergies. Even trace contamination can cause severe reactions.
Cross Contamination
Use clean utensils and surfaces when preparing this recipe for individuals with tree nut or milk allergies. Wash hands thoroughly between handling different ingredients.
Cooking Temperature
Roast peaches at recommended temperature (typically 375-400°F) until peaches are soft and edges are caramelized. Ensure crumble topping achieves golden brown color indicating proper doneness.
Handling
When working cold butter into flour with fingertips for crumble topping, ensure hands are clean and dry. Work quickly to maintain butter's cold temperature for optimal texture.
Storage
Store leftover crumble in airtight container in refrigerator for up to 3 days. Reheat in oven at 350°F until warmed through to restore crisp topping texture.
Allergen Warning
This dish contains milk products (butter) and tree nuts (walnuts). Always verify all ingredient labels for hidden allergens when sourcing ingredients.
Pro Tips
Technique
Keep your crumble butter cold—straight from the fridge, cubed and solid. When I was learning to bake in the Dordogne, my mentor would leave a block on the counter for exactly thirty seconds before we worked it in. That brief window of softness is all you need; any warmer and you'll end up with a paste instead of those beautiful rough pebbles that crunch and crumble.
Substitution
The nice thing about this filling is how generously it accommodates what's ripe. Swap the peaches for nectarines if you prefer a tarter bite, or try Italian prunes for an almost jammy depth. In autumn, I've used pears poached just until tender with a handful of dried cranberries folded through—still satisfying, still that contrast of soft fruit beneath the crunchy lid.
Time Saver
The crumble topping can be made up to three days ahead and stored in an airtight container in the fridge. When you're ready to bake, just scatter it straight onto your roasted fruit—no need to bring it to room temperature. This means you can prep the components separately and assemble in minutes when guests arrive.
From the chef
Ripe peaches go into the oven halved and face-down, and what comes out is entirely different — edges caramelized to a deep amber, butter pooled in every crevice, the fruit collapsed into something jammy and concentrated. The crumble topping is cold butter worked into flour, oats, and roughly chopped walnuts until it just holds together in rough, craggy pieces. A whisper of cinnamon and a hit of lemon zest keep it honest. Pile it over the hot fruit and let the whole thing cool just enough that the top stays genuinely crunchy where it meets the soft, yielding peaches underneath.
