Fall is fast approaching, and so is the season of apples. I love apple desserts, but sometimes it’s just not practical to make a pie. This is where my slow cooker comes in handy! You can make an easy slow cooker apple crisp with a buttery, brown sugar, cinnamon oat topping without ever turning on your oven.
This recipe makes making an apple crisp a breeze! The apples are cooked down with sugar and cinnamon until soft and tender and topped with oats that get all crispy in the crockpot. You’ll never want another apple crisp recipe again!
Best Apples for Apple Crisp
I like to use green apples that are nice and tart, but you can use any type. I used three large granny smith apples to make this recipe. If the apples at your local supermarket are more on the medium-small side I would get four or five.
If the green apples are looking weathered you can also use Cortland, Fuji, Braeburn, Jonagold, etc. What you want is an apple that is known to be crisp with some tartness. If you go for a soft, sweet apple, you may end up with an apple crisp that tastes like pure sugar and mush.
INGREDIENTS & EQUIPMENT
Below is a list of ingredients with some helpful tips and suggestions for substitutions. Scroll all the way down for the full, printable recipe card with amounts & instructions.
Ingredients for the Fresh Apple Crisp Filling:
APPLES – Use a tart apple. I used Granny Smith but Cortland, Fuji, Braeburn will also work.
LEMON – You’ll squeeze the juice of half a lemon over the apples to keep them from browning.
SUGAR – Granulated white sugar.
FLOUR – All purpose flour.
CINNAMON – Use a high quality cinnamon for the best flavor.
Cinnamon Oat Crumble Ingredients:
FLOUR – Again, all purpose white flour.
OATS – Old fashioned oats. Quick oats will not leave you with the same crisp texture.
SALT – To balance all the sweet.
CINNAMON – Again, high quality cinnamon, like ceylon.
BUTTER – Cold, cubed butter will be cut into the oats to make the crumble.
TOOLS FOUND ON AMAZON TO HELP YOU
This apple crisp recipe doesn’t use anything too fancy as far as equipment goes. All you’ll need is a slow cooker, two medium-large mixing bowls, an apple peeler/corer, and a pastry cutter. If you don’t have an apple corer or pastry cutter on hand, you can use a regular fork. Both kitchen tools are handy to keep around, though, so think about adding one or both to your kitchen.
HOW TO MAKE EASY SLOW COOKER APPLE CRISP
Make The Slow Cooker Apple Crisp Filling:
STEP ONE: Prep the apples. Spray the slow cooker with non-stick spray. Wash, peel, and slice the apples to approximately 1/2″ thick and add them to the slow cooker. Squeeze the juice of half a lemon over the lemons & stir to coat.
STEP TWO: Make the sugary mixture. Stir together the sugar, flour, and cinnamon in a small bowl and pour over the apples. Stir to evenly coat.
Make The Brown Sugar Cinnamon Oat Crumble:
STEP THREE: Make the topping. To another small bowl, stir together the flour, oats, brown sugar, salt, and cinnamon. Add in the cold, cubed butter. Use a pastry cutter, or a fork, to incorporate the butter to the oat mixture. It will be crumbly. Pour the mixture evenly over the apples.
STEP FOUR: Cook. Line paper towel under the lid to help collect condensation and keep the topping crisp. Cook on HIGH for 1.5 hours. Remove the lid and cook for another 30-60 minutes to allow the topping to crisp.
Serve & enjoy!
SLOW COOKER APPLE CRISP FAQs
Can I use canned apple pie filling instead of fresh apples in this recipe?
If you’re craving an apple crisp but don’t have any fresh apples and happen to have a can of apple pie filling in the pantry in a pinch, it will work. Just be sure to eliminate the sugar, flour, and cinnamon. The cooking time will also be cut down to about 30 minutes with the lid on, instead of an hour and a half for the fresh apples.
Is apple crisp the same as apple crumble? What about cobbler?
Nope! While they are very similar, it’s the topping that differentiates each delicious apple dessert. What makes an apple crisp, well, a crisp is the oat topping. Crumbles don’t contain oats (see my blackberry crumble), and cobbler is made with a biscuit/cake-like topping mix.
How do I serve it?
This crockpot apple crisp is delicious served with a scoop of vanilla ice cream (just like my crockpot lava cake!), whipped cream, or just plain. It’s great for any holiday gathering and so easy to make ahead!
Can you use quick oats instead of rolled oats for crockpot apple crisp?
I do not recommend using quick oats in this recipe because the oat topping will be thin and will be missing that crispy texture you’re looking for. You’ll get a much better result with rolled oats or old-fashioned steel-cut oats.
How to keep apple crisp from getting soggy when storing?
On the off chance that you have any leftovers, you’ll want to store them in an air-tight container in the fridge. The oat topping will absorb some moisture from the apples, making it soggy. There isn’t anything you can do to prevent this.
The apple crisp will still be delicious. It just won’t have that crispy crunch you get when eating it straight out of the slow cooker. You can do a low broil to help pull some of the moisture out and crisp the oats back up. If you do this, make sure to watch it carefully, as it will burn before you can blink!
