Ingredients

Scale
  • 6 large apples (about 2.5 lbs), peeled, cored, and sliced (preferably a mix of Granny Smith and Honeycrisp)
  • 2/3 cup granulated sugar (or coconut sugar)
  • 2 tbsp all-purpose flour (or gluten-free flour)
  • 1 1/2 tsp ground cinnamon
  • 1/4 tsp ground nutmeg
  • 2 tbsp unsalted butter, melted
  • 1 tbsp lemon juice
  • 1/4 tsp kosher salt
  • 1 cup old-fashioned rolled oats
  • 2/3 cup all-purpose flour (or gluten-free blend)
  • 2/3 cup light brown sugar, packed
  • 1/2 cup unsalted butter, cold and cubed
  • 1/2 tsp ground cinnamon
  • 1/4 tsp ground ginger (optional)
  • 1/4 tsp kosher salt
  • 1/2 cup chopped walnuts or pecans (optional)

Instructions

  1. Grease the inside of a 5- to 6-quart slow cooker with butter or nonstick spray.
  2. Peel, core, and slice the apples into 1/4-inch thick slices. Place in a large mixing bowl.
  3. Add 2/3 cup sugar, 2 tbsp flour, 1 1/2 tsp cinnamon, 1/4 tsp nutmeg, 2 tbsp melted butter, 1 tbsp lemon juice, and 1/4 tsp salt to the apples. Toss until evenly coated.
  4. In a separate bowl, combine 1 cup oats, 2/3 cup flour, 2/3 cup brown sugar, 1/2 tsp cinnamon, 1/4 tsp ginger, 1/4 tsp salt, and (optional) 1/2 cup chopped nuts.
  5. Add 1/2 cup cold, cubed butter to the topping mixture. Use a pastry cutter, fork, or your hands to work the butter in until the mixture forms pea-sized crumbs.
  6. Pour the apple mixture into the greased slow cooker and spread into an even layer.
  7. Sprinkle the crisp topping evenly over the apples without pressing it down.
  8. Cover and cook on high for 2 to 2.5 hours or on low for 3.5 to 4 hours, until apples are fork-tender and topping is golden brown.
  9. Optional: For an extra-crispy topping, transfer the cooked crisp to a broiler-safe dish and broil for 2-3 minutes until golden and crisp. Watch closely.
  10. Let the crisp rest with the lid off for 10-15 minutes before serving to allow the juices to thicken.
  11. Serve warm, optionally topped with vanilla ice cream, whipped cream, or Greek yogurt.

Notes

Use a mix of tart and sweet apples for best flavor. For gluten-free, use gluten-free flour and oats. For vegan/dairy-free, use coconut oil or vegan butter. The broiler step is optional but adds extra crunch to the topping. Letting the crisp rest before serving helps the filling thicken. Store leftovers in the fridge for up to 4 days or freeze for up to 2 months.
