Easy Peach Crumble for Juicy Summer Dessert

The smell of peaches bubbling with cinnamon and butter in a hot oven—that's summer in a dish. This easy peach crumble is exactly that: juicy, sweet fruit under a blanket of crisp, buttery oat topping. No complicated steps, no fancy equipment. Just ripe peaches, a handful of pantry staples, and about an hour of your time.

The key to a great crumble is the ratio. I keep the topping at roughly equal parts flour, oats, and brown sugar by volume, with enough cold butter to bind it into clumps. That gives you a topping that stays crunchy even after the fruit releases its juices. For the peaches, a light coating of cornstarch and sugar draws out just enough liquid to create a syrupy filling without making it runny.

Choosing and Prepping the Peaches

For the best flavor, use peaches that are ripe but still firm—they should yield slightly to gentle pressure and smell fragrant at the stem. If your peaches are underripe, let them sit on the counter for a day or two. Overripe peaches will break down too much during baking and make the filling mushy.

Slice the peaches about ½-inch thick. Thicker slices hold their shape better; thinner slices will melt into the filling. I leave the skins on for texture and color, but you can peel them if you prefer (see FAQ for a quick method). Toss the slices with sugar, lemon juice, cornstarch, and spices. The lemon juice brightens the fruit and helps the cornstarch thicken the juices.
