Ingredients You’ll Need
- 5 cups peaches, sliced: Fresh juicy peaches are ideal for this crisp. If they’re out of season, canned peaches (drained) or frozen peaches can work too.
- 1/2 cup sugar: Just enough sweetness to complement the natural sugar in your peaches. Adjust to taste if your peaches are super sweet.
- 2 tbsp cornstarch: Helps thicken the juices released during baking, ensuring a hearty filling.
- 1/2 tsp vanilla: For that delightful aromatic essence in the background. Pure vanilla extract is always best.
- 1 tbsp lemon juice: Brightens the flavors of the peaches; freshly squeezed is recommended.
- 1/2 cup flour: All-purpose flour will give structure to the topping, but you can substitute with almond or coconut flour for a gluten-free option.
- 1/2 cup brown sugar: Adds a hint of richness and moisture to the topping.
- 1 tsp cinnamon: Elevates the flavors with a warm spice that pairs beautifully with peaches.
- 1/2 cup butter, cold & cubed: Cold butter helps create that coveted crumbly texture in the topping.
- 3/4 cup old-fashioned rolled oats: Adds texture and chewiness, giving the topping a rustic feel.
How to Make Simple Peach Crisp Recipe with Oat Topping
- Preheat the oven: Start by preheating your oven to 350 degrees Fahrenheit. While that’s warming up, prepare your baking dish by spraying a pie pan with non-stick spray.
- Prepare the peaches: Pit, peel, and slice enough peaches to fill 5 cups. Pour these juicy slices into a medium bowl.
- Mix the filling: Stir in 1/2 cup sugar, 2 tablespoons cornstarch, 1/2 teaspoon vanilla, and 1 tablespoon lemon juice. Mix gently until the peaches are well-coated and let them sit for about 10 minutes.
- Transfer to the pan: Pour the peach mixture into your prepared pie pan, spreading it out evenly.
- Make the topping: In a food processor, pulse together 1/2 cup flour, 1/2 cup brown sugar, and 1 teaspoon cinnamon until well combined. Add in the cold, cubed butter, pulsing until the mixture resembles coarse crumbs. Finally, mix in 3/4 cup old-fashioned rolled oats until just combined.
- Top the peaches: Evenly pour the oat mixture over the peach filling, ensuring it’s all covered for that crunchy bite.
- Bake: Place the pie pan in the oven and bake for 30–35 minutes, or until the topping is golden brown and the filling is bubbling around the edges.
Storing & Reheating
Store any leftovers at room temperature for up to 2 days. If you’re looking to keep it longer, refrigerate it in an airtight container for up to 5 days. For long-term storage, you can freeze the baked crisp for up to 3 months. When you’re ready to enjoy, simply reheat it in a 350-degree Fahrenheit oven for about 15-20 minutes, or until warmed through. Just note that the topping may soften after freezing, but if you pop it back in the oven, it’ll regain some of its original crunch.
Chef’s Helpful Tips
- Avoid overmixing the topping; a few lumps of butter are perfectly fine as they help create that flaky texture.
- Make sure your peaches are ripe for the best flavor—firm but slightly soft to the touch is key.
- For added complexity, consider tossing in a handful of chopped nuts or coconut flakes into the topping for an extra crunch.
- If you want to enhance the peach flavor even more, try adding a dash of almond extract to the peach mixture.
- This dish is delicious warm, but you can also serve it chilled if you prefer.
The beauty of this simple peach crisp recipe with oat topping is in its simplicity and versatility. Not only does it provide a robust flavor profile, but it also invites you to make it yours. You can play around with spices, fruit combinations, and even toppings like whipped cream or ice cream.
