Why I Love Slow Cooker Apple Crisp
Back when I first started cooking as a teenager, apple desserts were one of the first things I felt confident making. There’s something reassuring about the familiar scent of cinnamon and apples softening over heat—it reminds me of chilly afternoons in my mom’s kitchen. Now that I run Mastered Recipes, I love bringing those same warm, cozy feelings to new home cooks through dishes like this Slow Cooker Apple Crisp.
Ingredients List
- 6 medium apples (peeled, cored, and sliced)
- 1 cup old-fashioned oats
- 1 cup brown sugar (divided)
- 1/2 cup all-purpose flour
- 1/2 cup butter (melted)
- 1 tsp ground cinnamon
- 1/2 tsp ground nutmeg
- 1/4 tsp salt
Step-by-Step Instructions
- Peel, core, and slice the apples. In a large bowl, toss them with 1 tsp cinnamon, 1/2 tsp nutmeg, and about 2 tablespoons of the brown sugar.

- Spread the apple mixture evenly in the bottom of your slow cooker.

- In a separate bowl, combine the oats, flour, remaining brown sugar, and salt. Pour in the melted butter and stir until crumbly.

- Sprinkle the topping evenly over the apples in the slow cooker.

- Cover and cook on HIGH for 3 hours or LOW for 5–6 hours, until the apples are soft and the topping is golden and crisp around the edges.

- Serve warm. It’s especially delicious with a scoop of vanilla ice cream or a drizzle of caramel sauce.

Variations, Serving & Storage Tips
- Add-ins: Mix in chopped pecans, walnuts, or raisins with the topping for added texture.
- Make it gluten-free: Substitute the flour with almond flour or a gluten-free baking mix.
- Dairy-free version: Use coconut oil or vegan butter instead of regular butter.
- Storage: Cover and refrigerate leftovers for up to 3 days. Reheat gently in the oven or microwave.
- Serve with: Vanilla ice cream, whipped cream, or Greek yogurt make this dish shine.
Frequently Asked Questions
Can I use quick oats instead of old-fashioned?
Old-fashioned oats give a better texture. Quick oats can become mushy during the long cook time.
How do I keep the topping from getting soggy?
Place paper towels under the lid while cooking to absorb moisture and help the topping stay crisp.
Can I prepare this in advance?
Yes. Prep the apples and topping separately, refrigerate, then assemble and cook when ready.
