This hearty peach crisp has been my go-to summer dessert for years. It perfectly balances the juicy sweetness of fresh peaches with a buttery, crunchy oat topping that makes every bite absolutely irresistible.
I first made this peach crisp for a backyard barbecue where it completely stole the show. Even my friend who claimed not to like fruit desserts went back for seconds and asked for the recipe. The smell of cinnamon and baking peaches still takes me back to that perfect summer evening.
Ingredients
- Fresh peaches Selecting firm but ripe peaches ensures the perfect texture after baking
- Granulated sugar Enhances the natural sweetness of the peaches
- All purpose flour Helps thicken the peach filling and creates structure in the topping
- Cornstarch Critical for thickening the peach juices without making them cloudy
- Ground cinnamon Adds warmth and depth to both the filling and topping
- Salt Balances sweetness and enhances all flavors
- Light brown sugar Creates a caramel like flavor in the topping
- Salted butter Room temperature butter blends perfectly into the crisp topping
- Old fashioned oats Provides the signature hearty texture and nutty flavor
Step-by-Step Instructions
- Prepare the Oven and Pan
- Preheat your oven to 400°F. Take a moment to thoroughly butter your 9x9 baking pan, making sure to get into the corners. This prevents sticking and adds a subtle richness to the edges of your crisp.
- Mix the Peach Filling
- In a large bowl, gently combine the sliced peaches with granulated sugar, 2 tablespoons flour, cornstarch, 1 teaspoon cinnamon, and salt. Toss everything together until each peach slice is evenly coated. The sugar will start drawing out juices, creating a syrupy base. Pour this mixture into your prepared pan, spreading it evenly.
- Create the Crisp Topping
- Using the same bowl, combine brown sugar, remaining flour, butter, and remaining cinnamon. Mix until you have a moist, clumpy texture. Add the oats and work them in gently. The mixture should resemble coarse crumbs with varying sizes for the perfect texture contrast.
- Assemble and Bake
- Sprinkle the oat mixture evenly over the peaches, creating a generous blanket of topping. Bake for 20 to 25 minutes, watching for the edges to turn a light golden color. The filling should be bubbling around the sides when it's ready.
- Rest and Serve
- Allow your crisp to rest for 10 minutes after removing from the oven. This crucial step lets the filling thicken and the flavors meld together. Serve warm with a scoop of vanilla ice cream for the ultimate comfort dessert experience.

The magical moment in this recipe happens when the butter in the topping melts into the oats and sugar, creating pockets of caramelized goodness. My grandmother taught me to use a combination of white and brown sugars for the perfect balance of sweetness and depth. Whenever I make this recipe, I think of her kitchen filled with the aroma of baking peaches.
Make Ahead Magic
This peach crisp is perfect for preparing in advance. You can assemble the entire dish up to 24 hours before baking and store it covered in the refrigerator. Just remember to take it out about 30 minutes before baking to take the chill off. This makes it perfect for entertaining when you want to focus on your guests instead of last minute dessert preparation. The flavors actually develop beautifully during this resting time.
Peach Selection Secrets
The success of this crisp depends largely on choosing the right peaches. Look for fruits that yield slightly to gentle pressure but aren't mushy. The perfect peach for baking should smell fragrant and sweet at the stem end. If your peaches are still firm, you can ripen them by placing them in a paper bag with a banana for 1 2 days. Never refrigerate unripe peaches as this stops the ripening process and affects their flavor development.
Serving Suggestions
While vanilla ice cream is the classic pairing, this peach crisp opens up a world of serving possibilities. Try it with a dollop of lightly sweetened whipped cream, a spoonful of Greek yogurt for a tangy contrast, or even a drizzle of caramel sauce. For brunch, serve it warm with a splash of heavy cream. If you are feeling adventurous, try a scoop of cinnamon or butter pecan ice cream instead of vanilla. The crisp also makes a decadent breakfast when topped with a spoonful of ricotta and a drizzle of honey.
Recipe FAQs
- → Can I use frozen peaches instead of fresh?
Yes, you can use frozen peaches. Allow them to thaw completely in a colander or strainer to catch excess liquid. Once thawed and drained, proceed with the recipe as written. The texture will be slightly softer than when made with fresh peaches, but still delicious.
- → How do I select the best peaches for crisp?
Choose peaches that are just ripened but still firm. Over-ripe, soft peaches will become mushy when baked. Buy peaches a day or two in advance to ensure they reach the perfect ripeness without becoming too soft.
- → Can I make this peach crisp gluten-free?
Yes, use a reputable gluten-free all-purpose flour blend instead of regular flour for the streusel topping. For the peach mixture, skip the flour and add an extra 2 teaspoons of cornstarch instead. The texture may differ slightly, but it will still be delicious.
- → How can I prepare this dessert ahead of time?
Prepare the crisp without baking, wrap with plastic wrap or foil, and refrigerate for up to 24 hours. Before baking, let it sit at room temperature for 30-60 minutes, then bake as directed. Alternatively, fully bake the crisp, cool, and reheat in a 400°F oven for about 8 minutes or microwave individual servings.
- → How should I store leftover peach crisp?
Store in an airtight container in the refrigerator for up to 4 days. Reheat in an oven-safe dish at 400°F until heated through, or microwave individual portions in 30-second intervals until warm.
- → Can I double this peach crisp for a larger crowd?
Absolutely! Double all ingredients and bake in a 9x13 casserole dish. The baking time will increase by approximately 10 minutes. Check for doneness when the topping begins to turn golden around the edges.
