Ingredients You’ll Need
- 5 cups peaches, sliced: Look for ripe, juicy peaches for the best flavor. Feel free to mix in other fruits like berries or apples for a unique twist.
- 1/2 cup sugar: This enhances the natural sweetness of the peaches. You can substitute with coconut sugar or maple syrup for a different flavor profile.
- 2 tbsp cornstarch: This acts as a thickener, giving the peach mixture a lovely, saucy consistency.
- 1/2 tsp vanilla: A splash of vanilla adds depth to the sweet flavors, making it more inviting.
- 1 tbsp lemon juice: This brightens the peaches’ flavor and helps balance the sweetness. Fresh lemon juice is preferable.
- 1/2 cup flour: All-purpose flour works well here, but you can use a gluten-free blend if needed.
- 1/2 cup brown sugar: The molasses in brown sugar adds a rich, caramel-like flavor to the topping.
- 1 tsp cinnamon: This classic spice not only enhances the flavor profile but also adds a warm aroma as it bakes.
- 1/2 cup butter, cold & cubed: Use cold butter to create that perfect crumbly texture in the topping. Vegan butter can be substituted.
- 3/4 cup old-fashioned rolled oats: These oats give the topping its distinctive chewy texture, adding heartiness to the crisp.
How to Make Simple Peach Crisp Recipe with Oat Topping
- Preheat the oven and prepare the dish: Start by preheating your oven to 350 degrees Fahrenheit. Spray a pie pan with non-stick spray to make sure your crisp comes out easily after baking.
- Prepare the peaches: Pit, peel, and slice enough peaches to measure 5 cups. This might take some time, but fresh peaches make all the difference. Once sliced, pour them into a medium-sized bowl.
- Mix the fruit filling: In the bowl with the peaches, stir in 1/2 cup sugar, 2 tablespoons cornstarch, 1/2 teaspoon vanilla, and 1 tablespoon lemon juice until combined. This mixture will help the peaches release their juices while baking.
- Transfer to the baking dish: Pour the peach mixture evenly into the prepared pie pan, spreading it out nicely to ensure even cooking.
- Make the oat topping: In a food processor, pulse together 1/2 cup flour, 1/2 cup brown sugar, and 1 teaspoon cinnamon until combined. Then, add in 1/2 cup cold, cubed butter and pulse until you achieve a crumbly texture. Finally, gently fold in 3/4 cup old-fashioned rolled oats to maintain some texture.
- Top the peaches: Spoon the oat topping evenly over the peach layer in the pan. Make sure to cover all the fruit to protect it while baking.
- Bake to perfection: Place your pie dish in the preheated oven and bake for 30-35 minutes, or until the topping is golden brown and the peaches are bubbling around the edges. The aroma will fill your kitchen, and you’ll be counting down the minutes!
Storing & Reheating
To store your peach crisp, let it cool completely, then cover it with plastic wrap or aluminum foil. At room temperature, it will last for up to 2 days. For longer storage, refrigerate for up to a week in an airtight container. If you want to keep it for a more extended period, freeze it for up to 3 months. To reheat, simply pop it in a 350-degree oven for about 15-20 minutes until warmed. Do keep in mind that while reheating, the oat topping may lose some of its crispness, but a quick refresh in the oven can help revive its texture.
Chef’s Helpful Tips
- Make sure your butter is cold when mixing it into the topping; this will keep the crumble texture nice and light.
- If the peach filling appears too watery before baking, add a touch more cornstarch to thicken it up.
- Feel free to experiment with spices—you can add nutmeg or cardamom for a unique twist.
- If you prefer a sweeter topping, increase the brown sugar slightly, but remember, the peaches are naturally sweet.
- This recipe can easily be doubled—just ensure you use a larger pan to accommodate all that deliciousness!

Recipe FAQs
Can I use frozen peaches instead of fresh?
Yes! Frozen peaches can be a great alternative, especially when fresh ones aren’t in season. Just thaw and drain any excess liquid before mixing them with the other filling ingredients. You may want to add a little extra cornstarch to help thicken the filling since frozen fruit tends to release more moisture.
How do I know when my peach crisp is done?
Your peach crisp is ready when the topping is golden brown, and you can see the peach juices bubbling around the edges. A good visual cue is the edges starting to bubble up, creating a delicious sauce for the fruit underneath!
Can I make this peach crisp ahead of time?
Absolutely! You can assemble the peach mixture and topping ahead of time. Just cover and store them separately in the refrigerator. When you’re ready to serve, combine them and bake right before you’re set to enjoy a fresh dessert.
How should I serve this peach crisp?
Serve it warm from the oven with a scoop of vanilla ice cream for an indulgent treat, or pair it with a drizzle of cream for a sophisticated touch. It’s also delightful cold or at room temperature, making it a versatile dessert for any occasion!
