This easy slow cooker apple crisp with oatmeal crumble fills your house with warm, spiced aroma while you go about your day. The apples soften into a jammy, buttery filling while the oat topping turns golden and crisp around the edges.

Ingredients

Scale
  • 6 medium apples (mix of Granny Smith and Honeycrisp), peeled, cored, and sliced into ¼-inch thick pieces
  • ¼ cup granulated sugar
  • ¼ cup light brown sugar, packed
  • 1 tablespoon lemon juice
  • 1 teaspoon ground cinnamon
  • ½ teaspoon ground nutmeg
  • ¼ teaspoon salt
  • 2 tablespoons cornstarch
  • 1 cup old-fashioned rolled oats
  • ½ cup all-purpose flour
  • ½ cup packed light brown sugar
  • ½ teaspoon ground cinnamon
  • ¼ teaspoon salt
  • 6 tablespoons unsalted butter, cold and cut into small cubes
  • ½ cup chopped pecans or walnuts (optional)

Instructions

  1. Peel, core, and slice apples into even ¼-inch thick pieces. Toss with lemon juice in a large bowl.
  2. Add granulated sugar, brown sugar, cinnamon, nutmeg, salt, and cornstarch to the apples. Fold gently until every slice is coated. Let sit for 5 minutes.
  3. Lightly grease the slow cooker insert with butter or nonstick spray. Pour apple mixture in and spread into an even layer.
  4. In a medium bowl, combine oats, flour, brown sugar, cinnamon, and salt. Add cold butter cubes and work into dry ingredients using fingertips until mixture resembles coarse sand with some pea-sized butter lumps. Stir in nuts if using.
  5. Sprinkle crumble evenly over apples. Do not press down.
  6. Cover and cook on LOW for 3 to 4 hours or on HIGH for 1.5 to 2 hours, until apples are tender and filling is bubbly around the edges.
  7. Let crisp sit uncovered for 10 to 15 minutes before serving to allow filling to thicken.

Notes

Place a clean kitchen towel under the slow cooker lid to absorb condensation and keep topping crisp. Do not peek too often. Let crisp rest uncovered for 10-15 minutes before serving to thicken filling. For gluten-free, swap flour with 1:1 gluten-free baking flour or almond flour. For dairy-free, use coconut oil or vegan butter.
