Ingredients
- 6 medium apples (about 6 cups, peeled, cored, and sliced)
- 1 cup old-fashioned rolled oats
- ½ cup all-purpose flour
- ½ cup brown sugar, packed
- 1 teaspoon ground cinnamon
- ½ cup unsalted butter, melted
- 2 tablespoons granulated sugar
- 1 teaspoon vanilla extract
(Optional garnish: vanilla ice cream or whipped cream for serving.)
Cooking Instructions
Prepare the slow cooker.
Lightly coat the inside of your slow cooker with nonstick spray or a thin layer of butter. This prevents the crisp from sticking and makes cleanup much easier.
Slice the apples.
Peel, core, and thinly slice your apples into even pieces about ¼ inch thick. You can use a mix of sweet and tart apples, like Honeycrisp, Granny Smith, or Fuji, for a balanced flavor profile.
Season the apples.
In a large mixing bowl, toss the sliced apples with granulated sugar, cinnamon, and vanilla extract. Stir gently to coat each slice evenly. The blend of sweet and spice will form the base of your warm, fragrant filling.
Mix the crumble topping.
In a separate bowl, combine the oats, flour, brown sugar, and melted butter. Mix until the texture forms coarse crumbs that hold together when gently pressed. This buttery crumble will create the crisp, golden top you love.
Assemble the apple crisp.
Spread the apple mixture evenly onto the bottom of your slow cooker. Sprinkle the oat topping evenly over the apples, covering them completely. Don’t press it down too firmly, keeping the topping loose helps it crisp up.
Slow cook to perfection.
Cover the slow cooker and cook on high for 2 ½ to 3 hours, or on low for 4 ½ to 5 hours, until the apples are tender and bubbling and the topping turns golden brown along the edges.
Cool slightly before serving.
Turn off the heat and let the apple crisp rest for at least 15 minutes. This helps the syrupy apple filling thicken and makes serving easier.
Serve warm.
Spoon generous portions into bowls and top with a scoop of vanilla ice cream, a dollop of whipped cream, or a drizzle of caramel sauce. Enjoy the contrast of warm, cinnamon-spiced apples against the cold, creamy topping, it’s pure comfort.

Let us know how it was!Tips
- Apple choices: For best results, combine both tart (like Granny Smith) and sweet (like Honeycrisp or Gala) apples. Mixing varieties adds depth and prevents the dessert from becoming overly sweet.
- Substitutions: You can use coconut oil instead of butter for a dairy-free version, or gluten-free flour and oats for a gluten-free treat. Maple syrup can replace part of the brown sugar for a richer, more caramel-like flavor.
- Add-ins: For extra crunch, stir chopped pecans or walnuts into the topping. For a twist, add a pinch of nutmeg, cloves, or allspice to enhance the cozy spice aroma.
- Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave or in an oven-safe dish at 350°F until warmed through.
- Make-ahead tip: Assemble the apples and topping separately a day in advance. Store them in the fridge, then layer and cook the next day for an easy, freshly made dessert.

FAQs
- Can I use apple pie filling instead of fresh apples?
Yes, but reduce the sugar slightly since canned apple pie filling is already sweetened and spiced. - Do I need to peel the apples?
Peeling gives a softer, smoother texture, but you can leave the skins on for extra fiber and a rustic look. - Can I cook this recipe overnight?
It’s best not to, as the topping can get soggy if left too long. Use the low setting during the day for best results. - How do I make the topping crisper?
Remove the lid during the last 30 minutes of cooking to let some moisture escape, which will help the topping firm up. - Can I freeze slow cooker apple crisp?
Yes! Cool the crisp completely, then freeze in an airtight container for up to 2 months. Reheat in the oven until bubbly and warmed through.
