Why You’ll Love ThisPeach Crisp Recipe

  • Quick and easy to prepare with minimal fuss—slice, toss, top, and bake.
  • Uses everyday pantry staples like oats, flour, and brown sugar for the topping.
  • Naturally seasonal—showcases ripe peaches but adapts well to frozen fruit.

A Little Background

Fruit crisps are a classic American dessert born from the desire to stretch seasonal fruit into warm, rustic sweets. Unlike a pie, a crisp skips the bottom crust and focuses on a crunchy streusel-style topping, which lets the fruit shine. Peach crisps are especially popular in summer when peaches are at their juiciest, but the forgiving nature of this dish means you can enjoy it year-round with frozen peaches.

Key Ingredients for perfect Peach Crisp

  • Ripe Peaches: Sweet, juicy fruit sliced and tossed to form the filling.
  • Sugar & Lemon: Granulated sugar to sweeten and a squeeze of lemon juice to brighten.
  • Cornstarch: Thickens the peach juices so the filling isn’t runny.
  • Oat Crumble: Rolled oats, brown sugar and butter combined for a crunchy topping.
  • Warm Spices: Cinnamon (and a pinch of nutmeg) to enhance the peach flavor.

Step-by-Step Instructions to make Peach Crisp

  1. Preheat the oven to 350°F (175°C). Grease a 9×13-inch baking dish or similar-sized pan.
  2. Prepare the peaches: peel if desired, pit and slice about 6–8 medium peaches until you have roughly 6 cups of fruit. Place slices in a large bowl.
  3. Make the filling: toss the peaches with 1/2 to 3/4 cup granulated sugar (adjust to peach sweetness), 2 tablespoons cornstarch, 1 tablespoon lemon juice, and 1 teaspoon ground cinnamon. Let sit a few minutes, then transfer to the prepared baking dish.
  4. Prepare the topping: in a separate bowl combine 1 1/2 cups rolled oats, 3/4 cup brown sugar, 3/4 cup all-purpose flour, 1 teaspoon ground cinnamon, a pinch of salt, and 1/2 cup (1 stick) cold unsalted butter cut into small pieces. Use a pastry cutter or your fingers to blend until large crumbs form.
  5. Evenly sprinkle the oat crumble over the peach filling, covering it completely.
  6. Bake on the middle rack for 35–45 minutes, or until the topping is golden brown and the filling is bubbling around the edges.
  7. Remove from oven and cool at least 10–15 minutes to allow the filling to set. Serve warm with vanilla ice cream or whipped cream if desired.

Pro Tips & Variations

  • For extra crunch, stir 1/2 cup chopped pecans or almonds into the crumble.
  • Use frozen sliced peaches if fresh aren’t available—thaw and drain excess liquid before tossing with cornstarch.
  • Make-ahead: assemble the crisp, cover, and refrigerate for up to 24 hours; bake directly from chilled, adding a few extra minutes.

Serving Suggestions

Serve warm with a scoop of vanilla ice cream, a drizzle of caramel, or a dollop of whipped cream. This Peach Crisp is great for casual family dinners, summer potlucks, or as an easy holiday fruit dessert.

Equipment

  • 9×13-inch baking dish
  • Large Mixing Bowl
  • Measuring Cups & Spoons

Ingredients
  

Peach Filling

  • 6 cups peaches, peeled and sliced about 7–8 medium peaches
  • 1/2 cup granulated sugar
  • 2 tbsp cornstarch
  • 1 tbsp lemon juice fresh
  • 1 tsp vanilla extract
  • 1 tsp ground cinnamon
  • 1/8 tsp fine sea salt

Crisp Topping

  • 1 cup old-fashioned rolled oats
  • 3/4 cup all-purpose flour
  • 2/3 cup light brown sugar, packed
  • 1/2 tsp ground cinnamon
  • 1/4 tsp fine sea salt
  • 1/2 cup unsalted butter, melted slightly cooled
  • 1/2 cup chopped pecans optional, for extra crunch

Instructions
 

  • Preheat oven to 350°F (175°C). Lightly butter or spray a 9×13-inch baking dish.
  • Make the filling: In a large bowl, combine sliced peaches, granulated sugar, cornstarch, lemon juice, vanilla, cinnamon, and a pinch of salt. Toss until the fruit is evenly coated, then spread into the prepared baking dish.
  • Make the topping: In a medium bowl, whisk oats, flour, brown sugar, cinnamon, and salt. Drizzle in the melted butter and stir with a fork until moist clumps form. Fold in pecans, if using.
  • Assemble: Sprinkle the oat crumble evenly over the peach mixture, covering it from corner to corner without pressing it down.
  • Bake for 35 to 45 minutes, until the topping is golden brown and the peach juices are bubbling around the edges.
  • Cool for at least 10 to 15 minutes to set the juices. Serve warm, ideally with vanilla ice cream or whipped cream.

Notes

Fresh or frozen peaches both work. If using frozen, thaw completely and pat dry; add an extra teaspoon of cornstarch if the fruit seems very juicy.
To peel peaches easily, score an “X” on the bottoms, blanch in simmering water for 30 to 45 seconds, then shock in ice water and slip off the skins.
Leftovers keep 2 to 3 days in the refrigerator. Rewarm in a 325°F oven for 10 minutes to re-crisp the topping, or microwave individual portions briefly until heated through.
