This Slow Cooker Apple Crisp is tender Granny Smith apples generously coated in a sweet, cinnamon-spiced mixture, topped with a crunchy oat topping. The slow cooker does all of the work for an irresistible dessert perfect for any occasion! While your oven cooks the main dish, pull out your crockpot to handle the easy-to-follow and easy-to-make after-dinner treat! (I even enjoy some for breakfast with a dollop of yogurt or splash of milk!)

Ingredients & Substitutions

Apples: I like Granny Smith apples for their tartness. Season the apples with brown sugar, flour, and cinnamon. Other apples like Braeburn, Honeycrisp, Fuji, or Pink Lady apples would be delicious, too. Or, sometimes I like to mix and match different kinds of apples for the apple crisp.
Oats: Old-fashioned oats, also called rolled oats are perfect for recipes like apple crisp because they provide a hearty texture and hold their shape during cooking. Blend the oats with all-purpose flour, light brown sugar, and ground cinnamon. In a pinch, you could use instant oats (but I do not recommend those). They will cook faster and will have a softer texture.
Butter: Melted unsalted butter brings the oat mixture together. It also helps make the topping nice and crispy! Salted butter can also be used.

What To Serve With Apple Crisp For The Perfect Dessert

Slow Cooker Apple Crisp is delicious on its own, but sometimes I want a little more to elevate the experience! Hey, why not? Here are some great options to consider:

No-churn vanilla ice cream or salted caramel ice cream (my favorite)
Whipped Cream
Plain Greek Yogurt (great for a breakfast treat!)
Caramel Sauce
Toasted pecans or walnuts
Ready for the last idea??? Cheddar Cheese! Yep, add a slice of cheddar cheese to your pile of apple crisp! It does work! In fact, I also have apple cheddar sliders that blend sweet apples with cheddar cheese.

Creative Ways To Present Slow Cooker Apple Crisp

If you don’t want people simply scooping the apple crisp out of your slow cooker or crockpot, here are some creative ways you can serve it:

Serve the crockpot apple crisp in small, individual ramekins for an elegant and personalized touch.
Present the apple crisp in a small cast iron skillet for a rustic, homey look that holds heat well and adds visual charm.
Layer the apple crisp in mason jars, adding whipped cream or ice cream between the layers.
If you’re presenting the apple crisp at a fall gathering, place mini pumpkins, pinecones, or autumn leaves around the serving area to add a festive, seasonal feel.
Create a Toppings Bar! Set out small bowls with various toppings like chopped pecans, crushed graham crackers, caramel sauce, cinnamon sugar, and others I have mentioned. Guests can mix and match to create their perfect topping combinations.
For a classic and elegant finish, dust each serving lightly with confectioners’ sugar (powdered sugar) just before serving.

How To Store Slow Cooker Apple Crisp

To store the leftovers of crock pot apple crisp, first, let it cool to room temperature. Next, transfer it to an airtight container to store in the refrigerator. It will last up to 3-4 days. Reheat it in the microwave or the oven until heated through.

Can I Freeze Apple Crisp?

Yes, you can freeze the cooked apple crisp. To freeze, first, let the apple crisp cool completely. Next, keep it in a freezer-safe container, leaving a little room for expansion. The apple crisp will last up to 2-3 months in the freezer. When ready to enjoy, let the apple crisp thaw in the refrigerator overnight before reheating.

Ingredients

Filling

▢ 10 medium Granny Smith apples, peeled, cored, and sliced (about 10 cups)
▢ 1 cup (200 g) light brown sugar, packed
▢ 1 tablespoon all-purpose flour
▢ 1 teaspoon ground cinnamon

Topping

▢ 1 cup (90 g) old-fashioned oats
▢ 1 cup (125 g) all-purpose flour
▢ 1 cup (200 g) light brown sugar, packed
▢ 1 teaspoon ground cinnamon
▢ ½ cup (1 stick / 113 g) unsalted butter, melted

Instructions

Place sliced apples into the bowl of a slow cooker. Add brown sugar, flour, and cinnamon. Stir gently to make sure every piece of apple is covered in the sugar mixture.
In a medium bowl, combine the oats, flour, brown sugar, and cinnamon. Pour in the melted butter. Using a fork, mix everything together until coarse crumbs form.
Pour the oat mixture over the apples, spreading it out into an even layer.
Cover and cook on high for 2 hours, checking the apples at 1 ½ hours (or on low for 4 hours), or until the apples are softened.
Remove the lid. Cook for 20-30 more minutes, allowing the topping to crisp up slightly.
