Slow Cooker Apple Crisp is the ultimate cozy fall dessert. Tender cinnamon apples cook low and slow under a buttery, brown sugar oat topping until bubbly and golden. It’s my favorite for holidays, Sunday dinners, or fall entertaining when oven space is limited.
Serve it warm from the crockpot with your favorite topping, whether that’s a scoop of vanilla ice cream, a drizzle of caramel sauce, or simply enjoy it warm and cozy on its own.

Ingredient Notes

- Apples: Choose baking apples like Granny Smith, Honeycrisp, Braeburn, or Pink Lady so they turn tender without turning mushy. Cut slices into evenly sized pieces with or without peeling.
- Granulated Sugar: Reduce slightly if using especially sweet apples.
- Cinnamon: Adds classic warm flavor to the apple filling. Use apple pie spice for a more complex blend.
- Old Fashioned Rolled Oats: Give the topping a hearty, chewy texture and more crunch than instant oats.
- Butter: Use cold butter to make it easier to create coarse crumbs instead of a greasy topping.
Variations
- Mixed Apples: Combine tart and sweet varieties for more layered flavor.
- Nutty Crisp: Add chopped pecans or walnuts to the topping for extra crunch.
- Dried Fruit: Stir dried cranberries or raisins into the apples for a festive fall twist.

Storing Apple Crisp
Keep leftovers in an airtight container in the refrigerator for up to 4 days and in the freezer for 3 months. Freezing will soften the oat topping. Reheat in the microwave or in the oven.
