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.
The Crumble Topping: Technique Matters
This is where texture happens. Combine the dry ingredients—flour, oats, brown sugar, cinnamon, salt. Then add cold butter cut into small cubes. Use a pastry cutter, two forks, or your fingertips to work the butter into the dry mix. Stop when the mixture looks like coarse meal with some pea-sized butter pieces. Those little butter bits are what create flaky, crunchy clusters as the butter melts in the oven.
One common mistake: overworking the butter until it’s fully incorporated. You want distinct pieces of butter throughout. If the mixture starts to look like a uniform dough, you’ve gone too far. Pop it in the fridge for 5 minutes to re-chill if your hands are warm.
Assembling and Baking
Pour the peach filling into an 8×8-inch baking dish—glass or ceramic works best because they heat evenly. Spread the crumble topping evenly over the fruit. Don’t press it down; leave it loose so air can circulate and create crispness.
Bake at 375°F (190°C) for 30-35 minutes. You’ll know it’s done when the filling bubbles thickly around the edges and the topping is deep golden brown. If the topping browns too fast, tent loosely with foil after 20 minutes. Let the crumble cool on a wire rack for at least 15 minutes before serving. This rest time lets the filling set so it doesn’t run across the plate.
Serving and Storing
Serve warm, on its own or with a scoop of vanilla ice cream, a drizzle of heavy cream, or a dollop of whipped cream. The contrast of hot fruit and cold cream is classic for a reason.
Leftovers keep covered in the fridge for up to 3 days. To reheat, warm individual portions in a 350°F oven for about 10 minutes—the microwave will make the topping soggy. You can also reheat the whole dish, covered, in a 300°F oven for 15-20 minutes.
Substitutions and Variations
This easy peach crumble is flexible. Swap the peaches for nectarines, plums, or a mix of stone fruits. Add a handful of fresh blueberries or raspberries to the filling for extra color and tang. For a gluten-free version, use a certified gluten-free 1-to-1 flour blend (the oats should be certified gluten-free too). For dairy-free, substitute cold coconut oil or a plant-based butter—just keep it cold.
If you’re watching sugar, you can reduce the granulated sugar in the filling by half if your peaches are very sweet. The brown sugar in the topping adds both sweetness and structure, so I don’t recommend reducing it.
Takeaway: This easy peach crumble is the dessert you make when you want something impressive but effortless. The technique is simple, the ingredients are honest, and the result is a warm, fruity, crunchy bowl of comfort. Make it once, and you’ll have the ratio memorized.
Frequently Asked Questions
Can I use canned or frozen peaches for this easy peach crumble?
Yes, frozen peaches work well. Use 2 pounds of frozen sliced peaches (no need to thaw). Increase the cornstarch to 1 1/2 tablespoons and bake for 40-45 minutes. Canned peaches are not recommended as they are too soft and packed in syrup, which can make the filling watery and overly sweet.
Why is my peach crumble topping not crisp?
A soggy topping usually means the butter was too warm or the topping was overmixed. Use cold butter straight from the fridge, and work it into the dry ingredients only until you see pea-sized clumps. Also, make sure your oven is fully preheated and the crumble bakes long enough for the topping to brown.
Do I need to peel the peaches for peach crumble?
No, you do not need to peel peaches for this crumble. The skins soften during baking and add fiber and color. If you prefer a smoother texture, you can peel them by scoring an X on the bottom, blanching in boiling water for 30 seconds, then plunging into ice water—the skins will slip right off.

Method
- Preheat your oven to 375°F (190°C). Lightly grease an 8x8-inch baking dish. 2. In a large bowl, toss the sliced peaches with granulated sugar, lemon juice, cornstarch, cinnamon, ginger, and salt until evenly coated. Let sit for 5 minutes while you make the topping. 3. In a separate medium bowl, whisk together the flour, oats, brown sugar, cinnamon, and salt. Add the cold butter cubes. Use a pastry cutter or your fingertips to work the butter into the dry mixture until it resembles coarse meal with some pea-sized butter pieces. Do not overwork; you want clumps. 4. Pour the peach mixture into the prepared dish, spreading evenly. Sprinkle the crumble topping evenly over the peaches, covering completely. 5. Bake for 30-35 minutes, until the filling is bubbly around the edges and the topping is golden brown and crisp. If the topping browns too quickly, tent loosely with foil after 20 minutes. 6. Let cool on a wire rack for at least 15 minutes before serving. The filling will set as it cools. Serve warm, optionally with vanilla ice cream or whipped cream.
