Ingredients You’ll Need

5 cups peaches, sliced: Fresh, ripe peaches are best for natural sweetness and flavor. If out of season, consider using frozen peaches—just thaw and drain excess liquid.
1/2 cup sugar: This adds sweetness to the peach filling; you can also use brown sugar for a deeper flavor.
2 tbsp cornstarch: It thickens the peach juices, ensuring you don’t end up with a soupy dessert. Alternatively, try arrowroot powder for a gluten-free option.
1/2 tsp vanilla: Pure vanilla extract elevates the flavor of the peaches; don’t skimp on the quality!
1 tbsp lemon juice: A splash of acidity brightens the flavors and prevents browning.
1/2 cup flour: All-purpose flour binds the oat topping. You can use almond flour for a gluten-free version.
1/2 cup brown sugar: It provides a rich, caramel-like flavor to the topping.
1 tsp cinnamon: This warm spice enhances both the peaches and the oat mixture; feel free to adjust to your taste.
1/2 cup butter, cold & cubed: Cold butter helps create that perfect crumbly texture. For a dairy-free option, coconut oil works wonders.
3/4 cup old-fashioned rolled oats: These add incredible crunch and chewiness to the topping. Quick oats can be used, but they will yield a different texture.

How to Make Simple Peach Crisp Recipe with Oat Topping

Preheat the Oven: Start by preheating your oven to 350°F (175°C). Spray a pie pan with non-stick spray and set aside. This ensures your crisp doesn’t stick as it bakes.
Prepare the Peaches: Pit, peel, and slice enough peaches to measure 5 cups. Pour them into a medium bowl.
Mix the Peach Filling: Stir in 1/2 cup sugar, 2 tbsp cornstarch, 1/2 tsp vanilla, and 1 tbsp lemon juice until the peaches are well-coated.
Layer in the Pan: Pour the peach mixture into your prepared pie pan, spreading it out evenly.
Make the Oat Topping: In a food processor, pulse together 1/2 cup flour, 1/2 cup brown sugar, and 1 tsp cinnamon. Then, pulse in the cold, cubed butter until small crumbs form. Finally, gently pulse in 3/4 cup old-fashioned rolled oats.
Top the Peaches: Evenly pour the oat mixture over the peaches in the pan. This will create a deliciously crispy topping as it bakes.
Bake until Golden: Place in the oven and bake for 30-35 minutes, or until the top is golden brown and bubbling around the edges. Keep an eye out for that beautiful crust!

Storing & Reheating

To store your peach crisp, let it cool completely at room temperature. Cover with plastic wrap or aluminum foil and keep it in the refrigerator for up to 5 days. For longer storage, you can freeze it for up to 3 months. To reheat, simply pop it in the oven at 350°F (175°C) for about 15-20 minutes or until warmed through. Be aware that the topping may lose some crispness after freezing, but you can refresh it in the oven for a few minutes before serving.

Chef’s Helpful Tips

For the best texture, use cold butter; it helps create a crumbly topping that’s just delightful.
To avoid a soggy bottom crust, make sure to let the peach mixture drain a bit if using frozen peaches.
If you have too much juice, feel free to add a little more cornstarch to thicken it further.
Consider adding a dash of nutmeg along with the cinnamon for an extra layer of flavor.
To save time, slice the peaches ahead of time and store them in the fridge until you’re ready to bake.

There’s nothing quite like the comfort of a homemade peach crisp. It’s warm, inviting, and full of flavor that reminds you of summer days spent under the sun. As you take your first bite of the golden-topped dessert paired with luscious peaches, I hope you feel the same joy I did when I first baked this.
