Ingredients
  

  • 6-7 medium apples about 2 1/2–3 pounds, peeled, cored, and sliced 1/4-inch thick; use a mix like Granny Smith and Honeycrisp or Fuji
  • 1/2 cup light brown sugar packed, for the apple filling
  • 1 teaspoon ground cinnamon for the apple filling
  • 1/4 teaspoon ground nutmeg optional, for the apple filling
  • 1 tablespoon lemon juice
  • 1 teaspoon vanilla extract
  • 2 tablespoons cornstarch or arrowroot starch, to thicken the juices
  • 1 cup old-fashioned rolled oats do not use quick oats
  • 3/4 cup all-purpose flour use a 1:1 gluten-free flour blend if needed
  • 1/2 cup light brown sugar packed, for the topping
  • 1/4 cup granulated sugar
  • 1/2 teaspoon ground cinnamon for the topping
  • 1/4 teaspoon fine sea salt
  • 1/2 cup unsalted butter 1 stick, cold, cut into small cubes; if using salted butter, reduce added salt slightly
  • 1/2 cup pecans or walnuts chopped, optional
  • nonstick cooking spray or butter for greasing the slow cooker
  • vanilla ice cream, whipped cream, or vanilla Greek yogurt optional, for serving

Instructions
 

  • Lightly grease the bottom and sides of a 5–6 quart slow cooker with butter or nonstick spray to help prevent sticking and make cleanup easier.

  • Peel, core, and slice the apples about 1/4-inch thick, keeping the slices as even as possible so they cook at the same rate. If working slowly, toss the slices with a little lemon juice as you go to prevent browning.

  • In a large bowl, combine the sliced apples, 1/2 cup brown sugar, 1 teaspoon cinnamon, nutmeg (if using), lemon juice, vanilla, and cornstarch. Toss until every slice is well coated and no dry patches of cornstarch remain.

  • Spread the apple mixture evenly in the prepared slow cooker, pressing down lightly so there are no large air pockets. This helps the apples cook down into a soft, saucy layer.

  • In another large bowl, stir together the oats, flour, 1/2 cup brown sugar, granulated sugar, 1/2 teaspoon cinnamon, and salt. Add the cold butter cubes and work them into the dry ingredients with your fingers or a pastry cutter until the mixture resembles coarse crumbs with some pea-sized bits of butter. Stir in the chopped nuts if using.

  • Sprinkle the oat mixture evenly over the apples in the slow cooker. Do not pack it down firmly; leaving it a bit loose allows steam to circulate and helps the topping crisp up.

  • Cover and cook on LOW for 3–4 hours, or on HIGH for about 2 hours, until the apples are very tender when pierced with a fork and the topping looks set and lightly golden around the edges. Slow cookers vary, so start checking a bit early the first time.
  • For the last 20–30 minutes of cooking on LOW, prop the slow cooker lid slightly open with a wooden spoon if possible. This allows steam to escape and helps the topping firm up instead of becoming too soft.
  • Turn off the slow cooker and let the apple crisp rest for 10–15 minutes to thicken slightly. Spoon into bowls and serve warm with vanilla ice cream, whipped cream, or a dollop of vanilla Greek yogurt, if desired.

Notes

For best texture, use firm baking apples such as Granny Smith, Honeycrisp, Braeburn, or Pink Lady (or a mix). You can reduce the sugar in both the filling and topping by about 25–30% for a less-sweet, more breakfast-style crisp. Don’t skip the cornstarch or arrowroot—it thickens the juices into a glossy sauce instead of leaving them runny. A slow cooker crisp will be more tender and chewy on top than an oven-baked version; venting the lid near the end of cooking helps keep the topping from getting soggy.
