There’s something magical about walking into a home filled with the scent of cinnamon-spiced apples slowly caramelizing. That’s exactly what you’ll experience with this Slow Cooker Apple Crisp – all the comforting flavors of a traditional apple crisp without having to hover over the oven. This recipe transforms humble apples into a crowd-pleasing dessert while you’re busy doing other things (or nothing at all!).
If you’ve never made dessert in your slow cooker before, prepare to be amazed at how this kitchen workhorse handles one of fall’s most beloved treats.
The gentle, consistent heat creates perfectly tender apples swimming in their own caramelized juices, all topped with a crispy, buttery oat topping that will have everyone asking for seconds.
Why This Recipe is Awesome

This Slow Cooker Apple Crisp deserves a permanent spot in your recipe collection for so many reasons. First, it’s incredibly forgiving – even novice cooks can nail this dessert on the first try. The slow cooker does most of the work, transforming your ingredients into dessert perfection while you attend to other tasks.
What really sets this recipe apart is how it gives you the best of both worlds: incredibly tender, flavor-infused apples that maintain their shape without turning to mush, paired with that signature crispy topping we all fight over.
The slow cooking process allows the apples to release their juices gradually, creating a natural caramel-like sauce without any additional thickeners.
Unlike oven versions that can dry out, this method keeps everything wonderfully moist while still achieving that desirable textural contrast. Plus, it frees up your oven for other dishes, making it perfect for holiday meals or dinner parties when oven space is at a premium.

Slow Cooker Apple Crisp
Ingredients
- 6-7 medium apples about 2½ pounds – preferably a mix of Granny Smith and Honeycrisp
- ¼ cup granulated sugar
- 2 tablespoons lemon juice
- 1 tablespoon cornstarch
- 1 teaspoon ground cinnamon
- ¼ teaspoon ground nutmeg
- ¼ teaspoon salt
For the topping
- 1 cup old-fashioned rolled oats
- ¾ cup all-purpose flour
- ½ cup brown sugar packed
- ½ cup cold unsalted butter cubed
- 1 teaspoon ground cinnamon
- ¼ teaspoon salt
- ½ cup chopped pecans or walnuts optional
Instructions
- Prepare the slow cooker by lightly coating the inside with cooking spray or butter. This prevents sticking and makes cleanup easier.
- Peel, core, and slice the apples into ¼-inch thick slices. You want them thin enough to become tender but thick enough to maintain some structure during cooking.
- Combine the apple slices in a large bowl with granulated sugar, lemon juice, cornstarch, cinnamon, nutmeg, and salt. Toss gently until all slices are evenly coated with the mixture.
- Transfer the apple mixture to your prepared slow cooker, spreading it into an even layer.
- Make the topping by combining oats, flour, brown sugar, cinnamon, and salt in a medium bowl. Mix well.
- Cut in the cold butter using a pastry cutter, two forks, or your fingertips until the mixture resembles coarse crumbs. The butter should be pea-sized throughout the mixture.
- Stir in the chopped nuts if using. They add wonderful texture and flavor but the recipe works perfectly without them.
- Sprinkle the topping evenly over the apples in the slow cooker, covering the fruit completely.
- Place a clean kitchen towel under the slow cooker lid (making sure it doesn’t touch the food) to absorb condensation and help the topping crisp up. This step is crucial for achieving that perfect texture.
- Cook on LOW for 3-4 hours or on HIGH for 2 hours, until the apples are tender when pierced with a fork and the topping is golden brown.
- Remove the lid and towel and let the crisp rest for 20-30 minutes before serving. This allows the juices to thicken slightly.
- Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream for the ultimate comfort dessert experience.
Notes
- For the best flavor, use a mix of tart and sweet apples. Granny Smith provides structure and tartness, while Honeycrisp, Braeburn, or Jonagold add sweetness and depth.
- The kitchen towel trick is essential for achieving a truly crispy topping. Without it, condensation will drip back onto your topping, making it soggy.
- If you prefer an extra-crispy topping, you can transfer the cooked crisp to a baking dish and place under the broiler for 1-2 minutes (watch carefully!).
- This dessert can be made ahead and reheated, though the topping won’t be quite as crisp. It keeps well in the refrigerator for up to 3 days.
- For a gluten-free version, substitute the all-purpose flour with a 1:1 gluten-free flour blend and ensure your oats are certified gluten-free.

Common Mistakes to Avoid
- Skipping the towel under the lid – This crucial step prevents condensation from making your topping soggy. If you don’t have a towel, paper towels can work in a pinch.
- Slicing apples too thin – They’ll turn to mush during the long cooking time. Aim for ¼-inch thickness to maintain some texture.
- Using only one type of apple – Different varieties provide balance in flavor and texture. Using all sweet apples can make the dessert cloying.
- Opening the lid frequently – Each peek adds 15-20 minutes to cooking time as the slow cooker has to rebuild heat.
- Using warm or room temperature butter in the topping – Cold butter creates those desirable pockets of richness and texture. If your butter gets too soft, pop the topping mixture in the fridge for 10 minutes before using.
Alternatives & Substitutions
- Fruit variations: Pears work wonderfully in place of some or all of the apples. You can also add berries (fresh or frozen) or cranberries for a pop of color and tartness.
- Sugar alternatives: Replace white sugar with coconut sugar, maple syrup, or honey (reduce amount by 25% for liquid sweeteners). Brown sugar can be substituted with coconut sugar for a deeper flavor.
- Dairy-free option: Use coconut oil or plant-based butter alternatives in place of butter.
- Gluten-free adaptation: Use certified gluten-free oats and substitute a 1:1 gluten-free flour blend for the all-purpose flour.
- Spice variations: Add cardamom, ginger, or allspice for different flavor profiles. A splash of vanilla extract or bourbon in the apple mixture adds wonderful depth.
- Topping additions: Beyond nuts, consider adding shredded coconut, sunflower seeds, or a tablespoon of chia seeds to the topping for extra nutrition and texture.
FAQs
Can I make this Slow Cooker Apple Crisp ahead of time?
Absolutely! You can prepare both the apple mixture and topping up to 24 hours in advance and store them separately in the refrigerator. Combine them in the slow cooker when you’re ready to cook. Alternatively, cook the entire crisp ahead of time and reheat portions as needed (though the topping won’t be quite as crispy).
Why is my topping soggy instead of crisp?
The most common reason is skipping the towel under the lid. This catches condensation that would otherwise drip back onto your topping. Also make sure you’re not opening the lid frequently during cooking, as this creates extra steam. For extra insurance, some cooks leave the lid slightly ajar during the last 30 minutes of cooking.
Can I double this recipe for a larger crowd?
Yes, if your slow cooker is large enough (8 quarts or bigger). You may need to increase the cooking time by 30-60 minutes. For very large gatherings, consider using two slow cookers rather than overfilling one, which can lead to uneven cooking.
What’s the best way to serve Slow Cooker Apple Crisp?
This dessert shines when served warm with a scoop of vanilla ice cream that melts slightly into the warm apples. Whipped cream, caramel sauce, or even a drizzle of heavy cream are also delicious options. For breakfast, try it with a dollop of Greek yogurt.
Can I use quick oats instead of old-fashioned rolled oats?
While quick oats will work in a pinch, they’ll create a less defined texture in the topping. Old-fashioned rolled oats maintain their structure better during cooking, creating that signature “crisp” texture. Steel-cut oats aren’t recommended as they’ll remain too firm.
Final Thoughts
This Slow Cooker Apple Crisp embodies everything we love about comfort food – it’s simple, satisfying, and brings people together.
