- 6-7 ripe peaches, peeled, pitted, and sliced (about 6 cups)
- 1/4 cup granulated sugar
- 1 tablespoon cornstarch
- 1 teaspoon vanilla extract
- 1 teaspoon ground cinnamon (divided)
- 1 cup old-fashioned rolled oats
- 1/2 cup all-purpose flour

The cinnamon in both the fruit filling and topping ties all the flavors together with its sweet warmth, while the oats ensure the topping gets perfectly golden and crisp in the oven.
How do you make Best Peach Crisp Recipe with Cinnamon-Oat Topping step by step?
This method is straightforward and beginner-friendly. Each step is designed to maximize the dish’s flavor and texture while keeping cleanup simple.
Step 1 — Preheat the oven
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish or a similar-sized oven-safe dish to ensure easy cleanup.
Step 2 — Prepare the peach filling
In a large mixing bowl, combine the sliced peaches, granulated sugar, cornstarch, vanilla extract, and 1/2 teaspoon of ground cinnamon. Gently stir to coat the peaches evenly, then transfer the mixture to your prepared baking dish.
Step 3 — Make the oat topping
In a separate bowl, mix the oats, flour, brown sugar, remaining 1/2 teaspoon of ground cinnamon, and salt. Stir these dry ingredients until well blended.

Step 4 — Add the butter
Pour the melted butter over the oat mixture. Stir until the topping develops a crumbly texture that holds together lightly when pressed.

Step 5 — Assemble and bake
Evenly sprinkle the cinnamon-oat topping over the peach mixture. Bake in the preheated oven for 40-45 minutes, or until the topping turns golden brown and the peach filling bubbles around the edges.
Step 6 — Cool and serve
Remove the peach crisp from the oven and allow it to cool for 10-15 minutes. Serve warm, optionally topped with vanilla ice cream or whipped cream for extra indulgence.
Frequently Asked Questions About Best Peach Crisp Recipe with Cinnamon-Oat Topping

Yes, you can use canned (drained) or frozen (thawed and patted dry) peaches. Adjust the sugar slightly if using canned peaches in syrup.

What’s the best way to peel peaches?
Quickly blanch the peaches in boiling water for 30 seconds, then transfer them to an ice bath. The skins should slip off easily after this.
Can I make this recipe gluten-free?
Yes! Replace the all-purpose flour with a gluten-free baking blend. Ensure your oats are certified gluten-free as well.
Can I prepare this dish ahead of time?
You can assemble the crisp in advance and store it in the refrigerator for up to 24 hours. Bake just before serving for the best texture.
What is the history behind this classic dessert?
Fruit crisps have roots in early American and British baking traditions as a simple yet delicious way to use seasonal fruits. Peaches, in particular, gained popularity in crisp recipes due to their natural sweetness and juiciness.
Over time, adding oats to the topping became a signature twist, offering a heartier, crunchier texture than traditional flour-only toppings.

- Caramel drizzle: Elevate the flavors with a hint of caramel sweetness.
- Fresh berries: A handful of raspberries or blackberries adds a tart, refreshing touch.
Can you make ingredient swaps in this recipe?
Swapping ingredients is simple and allows you to customize your crisp. Here are a few options:
- Gluten-Free Flour: Replace all-purpose flour with a 1:1 gluten-free baking mix for those avoiding gluten.
- Maple Syrup: Substitute brown sugar with maple syrup in the oat topping for rich, caramel-like sweetness.
- Chopped Nuts: Add walnuts or pecans to the topping for extra crunch and a nutty flavor.
How to store and reheat your peach crisp
Leftovers can be stored in an airtight container in the refrigerator for up to 4 days. For freezing, cover the baking dish tightly and store for up to 3 months.
To reheat, warm individual servings in the microwave for 30 seconds to 1 minute. Alternatively, reheat the entire dish in a 350°F oven for 15-20 minutes to re-crisp the topping.
