Peach Crisp with Cinnamon-Oat Topping
Juicy baked peaches bubble under a buttery cinnamon-oat topping in this easy homemade peach crisp, the ultimate end of summer dessert ready in under an hour.
A Peach Crisp That Tastes Like Summer's Last Hurrah
There is something almost magical about ripe, juicy peaches bubbling away under a blanket of buttery, cinnamon-kissed oats. This peach crisp with oats is the kind of dessert that fills your kitchen with the smell of warm fruit and toasted brown sugar, and it comes together with shockingly little effort. If you have been searching for an easy homemade peach crisp to make the most of late summer fruit, this is the one to bookmark.
Unlike a peach cobbler or pie, there is no fussy dough to roll out here. Just sliced peaches, a few pantry staples, and a crumbly oat topping that turns deeply golden in the oven. It is rustic, forgiving, and endlessly comforting.
Before we get cooking, the right tools and ingredients really do make this recipe shine. A sturdy ceramic baking dish helps the topping crisp evenly, and using truly ripe, fragrant peaches makes all the difference between a good crisp and an unforgettable one.
Why This Recipe Works
This particular method for how to make peach crisp leans on a few small but important details:
- Cornstarch in the filling thickens the peach juices just enough so the crisp holds its shape on a plate, instead of turning into peach soup.
- A splash of lemon juice brightens the natural sweetness of the peaches and keeps the flavor from feeling one-note.
- Cold butter, worked by hand, creates those irresistible craggy clumps in the topping rather than a flat, sandy layer.
Chef's Tip: Resist the urge to overmix the oat topping. You want visible streaks of butter and uneven, pebbly clumps. That texture is exactly what gives this baked peaches with crisp topping its signature crunch.
Choosing and Prepping Your Peaches
The best peach crisp starts with the best peaches. Look for fruit that smells sweet at the stem end and gives slightly when pressed. Freestone peaches are easiest to slice since the pit pulls away cleanly, but clingstone varieties work too with a little extra patience.
Peeling is entirely optional. The skins soften beautifully in the oven and add a lovely rosy color to the filling, so feel free to skip that step if you are short on time. If your peaches are a touch underripe, let them sit on the counter for a day or two before baking. This is genuinely one of the best end of summer dessert ideas precisely because it adapts to whatever stage your fruit is at.
Building the Cinnamon-Oat Topping
This peach crisp recipe with oatmeal cookie topping style gets its irresistible texture from old-fashioned rolled oats combined with flour, brown sugar, and warm cinnamon. The brown sugar adds a deep, almost caramel-like sweetness that pairs perfectly with the peaches, while the oats give every bite a satisfying chew.
If you only have quick oats on hand, do not worry. A peach crisp with quick oats swap works just fine, you will simply get a slightly finer, softer topping instead of big chunky clusters. Either way, the result is golden, buttery, and impossible to resist straight from the oven.

Peach Crisp with Cinnamon-Oat Topping
Juicy baked peaches bubble under a buttery cinnamon-oat topping in this easy homemade peach crisp, the ultimate end of summer dessert ready in under an hour.
Ingredients
- 6 fresh peaches, pitted and sliced, peeling optional
- 3/8 cup granulated sugar, for the peach filling
- 1 tbsp cornstarch, helps thicken the juices
- 1 tbsp lemon juice, freshly squeezed
- 1 tsp ground cinnamon, divided between filling and topping
- 1 cup old-fashioned rolled oats, quick oats work too, see notes
- 1/2 cup all-purpose flour
- 1/2 cup brown sugar, packed, light or dark
- 1/2 cup unsalted butter, cold, cut into small cubes
- 1/4 tsp salt, fine sea salt
- 0 vanilla ice cream, optional, for serving
Instruction
Preheat your oven to 350 degrees F (175 degrees C) and lightly butter a 9-inch baking dish.
In a large bowl, toss the sliced peaches with granulated sugar, cornstarch, lemon juice, and half a teaspoon of cinnamon until evenly coated. Spread the mixture into the prepared baking dish.
In a separate bowl, combine the oats, flour, brown sugar, remaining cinnamon, and salt. Add the cold cubed butter and use your fingers or a pastry cutter to work it into the dry ingredients until the mixture looks like coarse, clumpy crumbs.
Sprinkle the oat topping evenly over the peaches, covering most of the fruit but leaving a few peeks of filling visible.
Bake for 35 to 40 minutes, until the topping is golden brown and the peach filling is bubbling around the edges.
Remove from the oven and let the crisp rest for 10 to 15 minutes before serving so the juices can set slightly.
Serve warm, with a scoop of vanilla ice cream if desired.
Equipment
- 9-inch baking dish
- Mixing bowls
- Pastry cutter or fork
- Sharp paring knife
Notes
Serving, Storing, and Make-Ahead Tips
Serve this crisp warm, ideally within 20 minutes of pulling it from the oven, when the topping is at its crunchiest and the filling is still gently bubbling. A scoop of vanilla ice cream melting into the warm peach juices is, frankly, non-negotiable in our house.
If you have leftovers, simply cover the dish and refrigerate for up to four days. The topping will soften slightly over time, but a quick reheat in the oven brings back much of that crisp texture.
Chef's Tip: Avoid covering the crisp tightly with plastic wrap while it is still warm. Trapped steam will make the topping soggy. Let it cool slightly first, then cover.
Whether you are making this for a backyard dinner party or simply treating yourself on a quiet Sunday, this peach crisp delivers everything you want from a late summer dessert: juicy fruit, a crunchy topping, and minimal effort for maximum reward.
