Ingredients

For the apple filling

6 cups apples peeled & sliced to approx. ½” thin
Juice of half a lemon
⅓ cup granulated sugar
2 Tablespoons flour
1 teaspoon cinnamon

For the oat topping

½ cup flour
¾ cup old fashioned oats
½ cup brown sugar
¼ teaspoon salt
1 teaspoon cinnamon
½ cup cold butter cubed

Instructions

Spray a 6 qt slow cooker with non-stick spray.
Lay sliced apples into the bottom of the slow cooker. Squeeze juice of half a lemon over apples and stir to coat.
6 cups apples, Juice of half a lemon
To a small bowl, stir together the sugar, flour, and cinnamon and pour over the apples. Stir to evenly coat.
⅓ cup granulated sugar, 2 Tablespoons flour, 1 teaspoon cinnamon
To another small bowl, stir together the flour, oats, brown sugar, salt, and cinnamon. Once evenly mixed, add in the cold, cubed butter. Use a pastry cutter, or a fork, to incorporate the butter to the oat mixture. It will be crumbly.
½ cup flour, ¾ cup old fashioned oats, ½ cup brown sugar, ¼ teaspoon salt, 1 teaspoon cinnamon, ½ cup cold butter
Once combined, sprinkle the topping evenly over the apples.
Line the top of the slow cooker basin with paper towel and place the lid on top (this helps collect condensation and keep the topping crisp). Cook on HIGH for 1.5 hours. Remove the lid and cook for another 30-60 minutes to allow the topping to crisp.
Serve warm or cold with whipped cream or vanilla ice cream.

Notes

Use crisp, tart apples like Granny Smith (3 large or 4–5 smaller ones).
Other good options: Cortland, Fuji, Braeburn, Jonagold.
Avoid soft, sweet apples—they can make the crisp overly sweet and mushy.
Canned apple pie filling works in a pinch—omit added sugar, flour, and cinnamon.
Store leftovers in an airtight container in the fridge for up to 3 days.

Every slow cooker runs differently. Times given are a general recommendation and should be tested in your own slow cooker and adjusted as needed.
