Servings 6 people


  • 3 lbs frozen sliced peaches thawed and drained (see note)
  • 3/4 cup granulated sugar
  • 2-3 tablespoons all-purpose flour


  • 1/2 cup brown sugar packed
  • 1/2 cup granulated sugar
  • 3/4 cup all-purpose flour
  • 3/4 cup oats (1-minute or old-fashioned oats) I used 1-minute oats
  • 1 ½ teaspoons cinnamon
  • ¼ teaspoon all-spice
  • teaspoon salt
  • 8 tablespoons unsalted butter chopped


  • Preheat oven to 350 F.
  • In a bowl stir together thawed and drained peaches and granulated sugar.
  • Stir flour into peaches until syrup has thickened. (may need more or less flour to thicken to your liking)
  • Using a slotted spoon, place peaches in a deep dish pie plate. (let the excess syrup drip off. See note). Set aside.
  • To make the toppings, in a separate bowl stir together brown sugar, granulated sugar, flour, oats, cinnamon, all-spice and salt until combined.
  • Cut in butter using your hands until mixture is crumbly.
  • Sprinkle topping evenly over peaches.
  • Bake for 35-45 minutes or until topping has browned and crisp. (May need longer)
  • Let crisp cool slightly to allow syrup to thicken, about 10-15 minutes.
  • Serve warm with a side of vanilla ice cream. Best served the same day. (Topping will not be as crisp the next day or when reheated.)



Peaches: If using fresh peaches allow them to sit in the sugar for about 30-40 minutes to soften them.
Syrup:If you do not like a very syrupy peach crisp, be sure to let the excess syrup drip off  completely before adding peaches to dish or add in enough flour or cornstarch to create a thicker syrup. Also be sure the peaches are FULLY thawed because any extra water will release when the peaches are heated.
Spices: Feel free to add cinnamon, lemon juice, vanilla or  other spices to the peaches if desired.
