Ingredients for Slow Cooker Apple Crisp
This recipe uses simple pantry staples paired with fresh apples and cranberries:
- 5 large Granny Smith apples: Peeled, cored, and sliced into 1/4-inch slices so they hold their shape without turning mushy.
- 1 1/2 cups fresh or frozen cranberries: Frozen berries go straight in without thawing and burst into a jewel-toned sauce.
- 1/4 cup granulated sugar + 2 tbsp cornstarch: Sweetens lightly and thickens the fruit juices into a glossy glaze.
- 1 tsp ground cinnamon + 1/4 tsp nutmeg + 1 tbsp lemon juice: Warm autumn spice and bright citrus lift.
- 1 cup old-fashioned rolled oats + 1/2 cup all-purpose flour + 1/2 cup packed brown sugar: Classic hearty streusel base.
- 6 tbsp cold unsalted butter, cubed: Cold butter is the secret to distinct crumbly clusters in the topping.
How to Make Slow Cooker Apple Cranberry Crisp
Follow these simple steps for tender spiced fruit and a set oat topping:
- Prep the Fruit Filling: Toss the sliced Granny Smith apples and cranberries in a bowl with granulated sugar, cornstarch, 1 teaspoon cinnamon, nutmeg, and lemon juice until evenly coated. Spread evenly across the bottom of a lightly greased 6-quart slow cooker.
- Cut In the Cold Butter: In a medium bowl, whisk together the rolled oats, flour, brown sugar, 1 teaspoon cinnamon, and kosher salt. Cut in the cold cubed butter using a pastry blender or your fingertips until coarse crumbs form.
- Layer and Slow Cook: Sprinkle the oat crumble evenly over the apple-cranberry layer. Cover and cook on HIGH for 2 1/2 to 3 hours (or LOW for 4 to 5 hours) until the apples are fork-tender and the fruit juices bubble enthusiastically around the edges.
- Vent the Lid for a Firmer Topping: For the final 30 minutes of cooking, prop the slow cooker lid slightly ajar with the handle of a wooden spoon so excess steam escapes and the oat topping sets cleanly. Serve warm with vanilla bean ice cream!

Frequently Asked Questions
Can I use frozen cranberries for slow cooker apple crisp?
Yes! Add frozen cranberries straight from the freezer without thawing. The cornstarch thickens any extra berry juice naturally as it simmers.
How do I keep the oat topping from getting soggy?
Propping the lid open slightly with a wooden spoon handle during the last 30 minutes releases trapped condensation and allows the buttery oat topping to set nicely.
