Peach Crisp with Cinnamon-Oat Topping
Juicy baked peaches under a buttery cinnamon-oat crumble, this easy peach crisp recipe with oats is the ultimate end-of-summer dessert ready in under an hour.
A Taste of Summer in Every Bite
There is something almost magical about the smell of peaches bubbling away under a buttery, cinnamon-spiced crumble. This peach crisp with oats is one of those desserts that feels both nostalgic and effortless, the kind of treat you can throw together on a weeknight or serve proudly at a summer gathering. If you have ever wondered how to make peach crisp that tastes like it came from a farmstand bakery, this is the recipe to bookmark.
Unlike a peach cobbler or pie, a crisp skips the fuss of rolling out dough. Instead, you get a thick, golden layer of toasted oats, brown sugar, and warm spice sitting on top of soft, syrupy peaches. It is rustic, it is forgiving, and it is one of the easiest end of summer dessert ideas you will ever make.
Before we get cooking, the right tools and ingredients make a real difference here. A sturdy ceramic baking dish helps the topping brown evenly without scorching, and good quality cinnamon and old-fashioned oats give the crumble its signature texture.

Why This Peach Crisp Recipe With Oatmeal Cookie Topping Works
The secret to a truly great crisp is the ratio between the fruit and the topping, plus making sure that topping actually crisps instead of turning soggy. This recipe leans on a few key details:
- Cornstarch in the filling thickens the peach juices just enough so you get a luscious, spoonable filling instead of a watery puddle.
- Cold, cubed butter worked into the dry ingredients creates pockets of fat that melt during baking, forming those irresistible craggy, golden clusters.
- A double dose of cinnamon, in both the filling and the topping, ties the whole dessert together with warm, cozy flavor.
Chef's Tip: Resist the urge to overmix the topping. You want clumpy, uneven crumbs, almost like a peach crisp recipe with oatmeal cookie topping. Smooth, sandy crumbs bake up flat instead of craggy and crisp.
Choosing and Prepping Your Peaches
For the best baked peaches with crisp topping, look for peaches that give slightly under gentle pressure but are not mushy. Freestone peaches are easiest to slice since the pit pulls away cleanly.
To peel them quickly, drop the peaches into boiling water for about 30 seconds, then transfer to an ice bath. The skins will slip right off with your fingers or a paring knife. If you are short on time, a vegetable peeler works just fine too, especially since the peel softens completely during baking anyway.
If peaches are out of season, frozen sliced peaches are a reliable substitute. Just thaw them fully and drain off the excess liquid before tossing them with the sugar and cornstarch, otherwise your easy homemade peach crisp can end up too watery.
Building the Crisp Topping
This topping is what really earns this dessert its name. Combining old-fashioned rolled oats with flour, brown sugar, and cinnamon gives you that classic chewy-crisp texture that a quick oats version simply cannot match, although peach crisp with quick oats is a totally acceptable shortcut if that is what you have on hand.
Work the cold butter into the dry mixture using your fingertips, a pastry cutter, or even a fork. You are aiming for a texture somewhere between coarse sand and small pebbles. A handful of chopped pecans or walnuts stirred in at the end adds a welcome bit of crunch and nutty depth, though it is completely optional.

Peach Crisp with Cinnamon-Oat Topping
Juicy baked peaches under a buttery cinnamon-oat crumble, this easy peach crisp recipe with oats is the ultimate end-of-summer dessert ready in under an hour.
Ingredients
- 6 cups fresh peaches, peeled and sliced, about 6 large peaches
- 3/8 cup granulated sugar, for the peach filling
- 1 tbsp lemon juice, freshly squeezed
- 1 tbsp cornstarch, helps thicken the peach juices
- 1 1/2 tsp ground cinnamon, divided between filling and topping
- 1/2 tsp salt, divided between filling and topping
- 1 cup old-fashioned rolled oats, quick oats may be substituted for a finer topping
- 3/4 cup all-purpose flour, for the crisp topping
- 1/2 cup brown sugar, packed
- 1/2 cup unsalted butter, cold, cut into small cubes
- 1/4 cup pecans, chopped, optional, walnuts also work
Instruction
Preheat the oven to 350 degrees F (175 degrees C). Lightly grease a 9x13 inch baking dish.
In a large bowl, toss the sliced peaches with granulated sugar, lemon juice, cornstarch, 0.5 teaspoon of cinnamon, and a pinch of salt until evenly coated.
Pour the peach mixture into the prepared baking dish and spread it into an even layer.
In a separate bowl, whisk together the oats, flour, brown sugar, remaining 1 teaspoon of cinnamon, and remaining salt.
Add the cold cubed butter to the dry topping mixture. Use your fingers or a pastry cutter to work it in until coarse, clumpy crumbs form.
Stir the chopped pecans into the topping, if using.
Sprinkle the oat topping evenly over the peaches, covering the surface completely.
Bake for 35 to 40 minutes, until the topping is deeply golden and the peach juices are bubbling at the edges.
Remove from the oven and let the crisp cool for 10 to 15 minutes before serving so the juices can set slightly.
Equipment
- 9x13 inch baking dish
- Large mixing bowls
- Pastry cutter or fork
- Measuring cups and spoons
- Cutting board and knife
Notes
Serving, Storing, and Variations
This crisp is best served warm, ideally about 15 minutes out of the oven, when the topping is still crackly and the filling is thick and glossy. A scoop of vanilla ice cream or a dollop of lightly sweetened whipped cream is practically non-negotiable.
Leftovers keep beautifully. Store the cooled crisp covered in the refrigerator for up to 4 to 5 days, and reheat individual portions in the oven to revive that crisp top rather than relying on the microwave alone.
Feeling like experimenting? Try folding in a handful of fresh blueberries or raspberries with the peaches, or swap the pecans for sliced almonds. However you make it, this peach crisp recipe with oats is destined to become one of your go-to easy homemade peach crisp desserts all season long.
