Ingredients You’ll Need

- 1/2 cup sugar: A blend of sugar draws out the natural sweetness of the peaches, enhancing their flavor.
- 2 tbsp cornstarch: This thickens the peach filling, giving it a luscious texture that holds together beautifully.
- 1/2 tsp vanilla: Pure vanilla extract adds a warm, aromatic depth that complements the fruity notes.
- 1 tbsp lemon juice: A touch of acidity balances the sweetness and enhances the peach flavor.
- 1/2 cup flour: All-purpose flour forms part of the topping, creating that lovely crunch.
- 1/2 cup brown sugar: Adds a rich, caramel-like depth to the topping that enhances the overall dessert.
- 1 tsp cinnamon: This warm spice elevates the flavors, offering a comforting depth and complexity.
- 1/2 cup butter, cold & cubed: Using cold butter helps form that perfect crumbly topping we all love.
- 3/4 cup old-fashioned rolled oats: Oats provide the ideal texture and heartiness to the topping.
How to Make Simple Peach Crisp Recipe with Oat Topping
- Preheat the oven to 350°F (175°C). Spray a 9-inch pie pan with non-stick spray to prevent the crisp from sticking.
- Prepare the peaches: Pit, peel, and slice enough peaches to yield 5 cups. Transfer them into a medium bowl.
- Mix the peach filling: Stir in 1/2 cup sugar, 2 tablespoons cornstarch, 1/2 teaspoon vanilla, and 1 tablespoon lemon juice until evenly coated.
- Pour into pan: Transfer the peach mixture into the prepared pie pan, ensuring it’s spread out evenly for even cooking.
- Make the topping: In a food processor, pulse together 1/2 cup flour, 1/2 cup brown sugar, and 1 teaspoon cinnamon until combined. Add the cold, cubed butter and pulse until crumbly. Gently fold in 3/4 cup rolled oats, stirring just until combined without overmixing.
- Add topping: Evenly sprinkle the oat mixture over the peaches, covering them completely. This will create a beautifully textured topping.
- Bake: Place in the oven and bake for 30-35 minutes, or until the topping is golden brown and the peach filling is bubbling around the edges.
Storing & Reheating
Store your leftover peach crisp at room temperature for up to 2 days, covered to keep it fresh. If you have more than you can eat, refrigerate it for up to 5 days in an airtight container. You can also freeze the crisp for up to 3 months by wrapping it tightly in plastic wrap and aluminum foil. To reheat, simply put it in a 350°F (175°C) oven for about 15-20 minutes until heated through. It’s worth noting that freezing may soften the crisp, but a quick reheat will revive its delectable charm.
Chef’s Helpful Tips
- Watch the peaches: If your peaches are very juicy, you might want to add a bit more cornstarch to absorb the excess moisture.
- Use cold butter: Keeping your butter cold ensures that the topping comes out crumbly rather than greasy—this is key!
- Mix gently: When incorporating oats into the topping, a light touch is important to keep the texture just right.
- Experiment with spices: You can boost flavor by adding nutmeg or ginger to the topping if you want something a little different.
- Make it ahead: The peach filling can be prepared a day in advance—just assemble and bake the day you plan to serve.
