Instructions — Step by Step
-
Prep the Apples
-
Peel, core and slice the apples into roughly ½‑inch thick slices.
-
In a large bowl, toss the apple slices with granulated sugar, flour, and cinnamon (and nutmeg/allspice if using). Make sure apples are evenly coated.
-
-
Grease the Slow Cooker
-
Lightly spray or butter the inside of a 4‑ to 6‑quart slow cooker to prevent sticking.
-
-
Fill the Slow Cooker
-
Arrange the apple mixture in the bottom of the slow cooker in an even layer.
-
-
Prepare the Crisp Topping
-
In a separate bowl, mix the oats, flour, brown sugar, cinnamon, and salt.
-
Add the cold butter cubes and use a pastry blender (or two forks / your fingers) to cut the butter into the dry mixture until it resembles coarse crumbs.
-
-
Top the Apples
-
Evenly sprinkle the oat‑butter mixture over the apples in the slow cooker.
-
-
Cook Slowly
-
Cover and cook on HIGH for about 2 to 2½ hours, or on LOW for 4–5 hours, until apples are tender but not mushy. The Foodie Physician+2Kristine’s Kitchen+2
-
Once done, remove the lid and let the crisp rest about 20–30 minutes (or set the slow cooker to “warm”) — this helps the topping firm up a bit and avoids sogginess. Slow Cooker Meals+1

-
Serve Warm
-
Spoon the apple crisp into bowls while still warm. Serve with a scoop of vanilla ice cream or a dollop of whipped cream.

✅ Tips & Variations
-
Best apple types: Use firm, slightly tart apples so they hold shape and don’t dissolve completely during cooking — Granny Smith, Honeycrisp, Braeburn work great. The Foodie Physician+1
-
Don’t peek too often: Every time you lift the lid, you let heat escape and moisture accumulates — this can make the topping soggy or extend cooking time. The Foodie Physician+1
-
Make ahead: You can prep the apple mixture (even the topping) ahead of time and keep refrigerated. When ready, assemble and cook — just account for possibly longer cooking time. Kristine’s Kitchen+1
-
Add-ins & upgrades: Mix chopped nuts (pecans, walnuts) into the topping for crunch; stir in a splash of apple cider or a pinch of ground cloves/ginger for fall‑spiced depth; swirl in caramel or a little maple syrup before serving.
-
Gluten‑free tweak: Use gluten‑free oats and substitute flour with a gluten‑free flour blend. The result is still delicious — just make sure your slow cooker lid is covered lightly to avoid excess moisture.
Why This Recipe Works
-
Apples soften gently in their own juices and sugar, releasing natural juices that turn into a lightly spiced, sweet‑tart sauce.
-
The oat‑butter topping bakes (slow‑cooks) into a crumbly, rustic “crisp” that contrasts the soft apples — that texture contrast is classic and satisfying.
-
Using a slow cooker means minimal hands‑on time and a lower risk of burning — letting the flavors meld over hours while you go about your day.
