This crockpot apple crisp keeps three spiral-cut apples in their whole-apple shape, with brown sugar oat crumble tucked into the centers and scattered around them.

Start it a few hours before dinner, then let the slow cooker handle dessert while you move on with your day. No peeling, no oven and no cutting the apples into little chunks!

I am obsessed with apples this time of year, but I am just as obsessed with making good use of my time. For this recipe, I use an apple corer and spiral slicer to do the cutting, leave the peels on to help the spirals hold together, and let the crockpot do the rest. My crockpot applesauce is another favorite when I want the apples to do most of the work!

The important thing to know: this is a soft, saucy apple crisp. The covered crockpot gives you tender apples and buttery cinnamon oat crumble, rather than a crunchy, oven-baked topping.

Spoon one into a bowl with the warm crumble and sauce, add vanilla ice cream and you have exactly the kind of fall dessert I want waiting after dinner.

Why This Recipe Works

Dessert cooks while you do something else. A little preparation earlier in the afternoon frees you up during the dinner rush.
The apples keep their shape without all the knife work. A spiral slicer cuts each apple into one continuous spiral that you gently press back together.
The crumble goes inside and around the apples. There is brown sugar, cinnamon and buttery oat mixture to spoon up with the tender fruit.
You do not need to peel the apples. The skins help support the spirals and save a prep step.
There is room to adjust as it cooks. Check the apples for tenderness and the surrounding crumble for moisture before serving. A little extra cooking time or water can help finish the batch.

Ingredient Notes

Apples: Use 3 very large apples, unpeeled and similar in size so they cook at approximately the same rate. Choose firm baking apples, such as Honeycrisp, Granny Smith or Pink Lady, to help preserve the presentation. Wash and dry them before coring and spiral-cutting.
Old-fashioned oats: Give the crumble its texture. Use rolled oats rather than steel-cut oats, which need different cooking conditions.
All-purpose flour: Combines with the butter, oats and sugar to form the crumble. Spoon it into your measuring cup and level the top rather than packing it in.
Brown sugar: Light or dark brown sugar works. Dark brown sugar adds a deeper molasses flavor.
Cinnamon and salt: Cinnamon brings the apple-crisp flavor, and a little salt balances the sweetness.
Salted butter: Melt 7 tablespoons for the crumble and reserve 3 tablespoons to place over the apple centers. Keep these portions separate during prep.
Water: Start with 2/3 cup, poured down the inside edge of the crockpot. Add more only if the surrounding crumble needs moisture as it cooks.
Ice cream and caramel sauce: Optional, but warm cinnamon apples with melting vanilla ice cream are hard to beat.

Equipment

Use a slow cooker that fits all three apples upright in a single layer with the lid fully closed. Avoid stacking them.

An apple corer and spiral slicer creates the continuous spirals that make this recipe different. I use this apple peeler/corer/slicer, with the peeling blade disengaged so the skins stay on. Follow your tool’s instructions for coring and slicing without peeling.

You will also need a mixing bowl, a small spoon for filling the centers and a broad serving spoon to support the apples when lifting them out.

How to Make Crockpot Spiral Apple Crisp

Prepare the apples. Coat the crockpot with cooking spray. Core and spiral-cut the unpeeled apples, keeping each spiral intact. Gently press each apple back into its original shape and stand it upright in the crockpot.

Mix the crumble. Melt 7 tablespoons of butter. Stir together the oats, flour, brown sugar, cinnamon and salt, then mix in the melted butter until evenly moistened and crumbly.

Fill the apples and add water. Spoon some crumble into each apple’s cored center, then scatter the remaining mixture around and between the apples. Add a little over the tops if desired. Slowly pour 2/3 cup water down the inside edge of the crockpot, avoiding the apple tops.

Top with butter and cook. Place 1 tablespoon of the reserved butter over each filled apple center. Cover and cook on High for 2 hours before checking for tenderness.

Check tenderness and moisture. Insert a thin knife into an apple. If it meets resistance, cover and cook for another 30 minutes. If the surrounding crumble looks dry, add 1/4 cup water over that portion, using up to 1/2 cup if needed. If it looks floury despite liquid in the bottom, gently stir only the surrounding crumble into the liquid and melted butter. Cover and cook another 20–30 minutes as needed, until the apples are tender and the crumble is cooked through.

Serve warm. Carefully lift the apples into bowls, supporting them from underneath. Spoon the crumble and sauce around them and finish with ice cream and caramel sauce.

Megan’s Tips

Keep the peels on. They help the spiral-cut apples stay together as they soften.
Use tenderness as your guide. Start checking after 2 hours. Apple size, variety and your slow cooker can all affect the timing.
Only add extra water where it is needed. Pour it over dry crumble around the apples, rather than washing the filling out of the centers.
Stir around the apples, not through them. This helps moisten any floury pockets without breaking up the spirals.
A little slumping is fine. If an apple opens up as you serve it, spoon the crumble and sauce around it. It will still make a wonderful bowl of dessert.

Simple Variations

Change the finish: Swap caramel sauce for a drizzle of maple syrup.
Add crunch at serving: Sprinkle toasted pecans or walnuts over each bowl. Adding them at the end keeps their crunch.
Skip the ice cream: Serve with whipped cream, or enjoy the warm apples and crumble on their own.

Storage and Reheating

Transfer leftovers to a shallow airtight container and refrigerate within 2 hours. Store in the refrigerator for up to 3–4 days, keeping ice cream and other toppings separate.

Reheat individual portions in the microwave in short intervals until hot throughout. Add a small splash of water if the crumble has thickened in the refrigerator. The apples and topping will soften further after storing and reheating.

Frequently Asked Questions

Does apple crisp get crispy in the crockpot?

This version has a soft, buttery oat crumble rather than a crisp, browned topping. The covered slow cooker traps moisture, creating tender apples with sauce to spoon around them.

Do I need to peel the apples?

No. Leave the peels on for this recipe. They help the spiral-cut apples hold their shape while cooking and serving.

Are the apples really left whole?

They keep their whole-apple shape, but they are cored and spiral-sliced before cooking. Each apple stays in one continuous spiral that is gently pressed back together.

Can I make this without a spiral slicer?

Yes! Core the apples, leaving the peels on and the apples whole, then fill and assemble as directed. Allow about 20 extra minutes of cooking time and add more water as needed to keep the surrounding crumble moist. Check that the apples are tender before serving.

Why does some of the crumble still look dry or floury?

Some pockets may not have come into contact with enough butter or cooking liquid. Gently stir the crumble around the apples into the liquid in the bottom. If that portion is dry, add a little water over it, cover and continue cooking until it is moistened and cooked through.

Can I cook this on Low or leave it overnight?

The method here uses High for about 2–3 hours, with checks toward the end. I do not have a tested Low or overnight cooking time for this version.

Make It a Cozy Fall Dinner

Start the apple crisp earlier in the afternoon, then make my meatloaf with crackers for dinner. Add mashed potatoes and green beans, and dessert is already underway! For a quicker main dish, try my Instant Pot meatloaf.
