Ingredients

Yip: you can find a full list of ingredients and measurements in the recipe card below.

8 cups peeled and thinly sliced fresh peaches
½ cup granulated sugar
½ cup + 2 tablespoons all-purpose flour, divided
1 tablespoon cornstarch
2 teaspoons ground cinnamon, divided
¼ teaspoon salt
¾ cup packed light brown sugar
½ cup (1 stick) salted butter, room temperature
1 ¾ cup old-fashioned oats

Instructions

Preheat the oven to 400°F (200°C).
Grease a 9×9-inch baking pan with butter and set aside.
Make the peach filling:
In a large bowl, mix together the peaches, granulated sugar, 2 tablespoons flour, cornstarch, 1 teaspoon of cinnamon, and salt until the peaches are fully coated. Pour the mixture into the prepared pan.
Make the oat topping:
In the same bowl, cream together the brown sugar, remaining ½ cup flour, softened butter, and remaining teaspoon of cinnamon until the mixture becomes clumpy. Add in the oats and mix until a crumbly, coarse mixture forms. (Using your hands works best here.)
Assemble and bake:
Sprinkle the oat topping evenly over the peach mixture. Bake for 20–25 minutes, or until the topping is golden and the peach filling is bubbling around the edges.
Cool and serve:
Let the peach crisp rest for at least 10 minutes before serving to allow it to set. Serve warm, optionally with a scoop of vanilla ice cream.

Variations

Use Frozen Peaches: Thaw and drain well before using.
Add Nuts: Chopped pecans or walnuts in the topping add crunch and flavor.
Spice It Up: Add nutmeg or ginger for a deeper spice profile.
Make It Gluten-Free: Use certified gluten-free oats and a 1:1 gluten-free flour blend.
Try Other Fruits: Swap some peaches for blueberries, raspberries, or nectarines.

Heating and Storage

To Store: Keep leftovers covered in the refrigerator for up to 4 days.
To Reheat: Warm in the oven at 350°F for 10–15 minutes or microwave individual portions for 30–45 seconds.
Freezing: Freeze after baking (fully cooled) in a freezer-safe container for up to 2 months. Thaw overnight and reheat before serving.

Frequently Asked Questions

Can I use canned peaches?

Yes, but make sure to drain them thoroughly and skip the sugar in the filling if they are already sweetened.

Do I need to peel the peaches?

For the best texture, yes. Peeling avoids any tough skin in the final dessert.

Can I make this ahead of time?

Absolutely. Assemble the peach crisp, cover, and refrigerate for up to 24 hours. Bake when ready.

Can I use quick oats instead of old-fashioned oats?

You can, but the texture will be softer and less chewy.

How do I keep the topping from getting soggy?

Be sure to bake until golden brown and let the crisp cool for 10 minutes so the topping sets.

Can I make this dairy-free?

Yes, substitute the butter with a plant-based butter.

How do I know when it’s done baking?

The edges should be bubbling and the topping should be golden brown.

What’s the best way to reheat leftovers?

Reheat in the oven at 350°F for a crisp topping or microwave individual portions for quick servings.

Can I cut the recipe in half?

Definitely—just bake it in a smaller pan like an 8×4 loaf pan and reduce the baking time slightly.

Is this dessert freezer-friendly?

Yes, you can freeze it after baking. Just cool completely and wrap well.
