Low Sugar Crockpot Apple Crisp

Total time3 hr 15 min

Prep time15 min

Cook time3 hr

Tender Granny Smith and Honeycrisp apples slow-cook down into a jammy, cinnamon-and-nutmeg-spiced filling, thickened with a touch of cornstarch and brightened with fresh lemon juice. On top, a crumbly blanket of old-fashioned oats and cold butter, rubbed together into coarse, buttery clumps, bakes low and slow until it turns golden at the edges. The paper-towel trick keeps that topping from going soggy in the slow cooker, so you still get real texture contrast between the soft fruit and the crisp crumble. Finish it under the broiler for a few minutes if you want extra crunch, then spoon it warm into bowls with ice cream or whipped cream. It's a cozy, low-effort dessert that fits neatly into an added sugar free routine without skipping the comfort of a classic apple crisp.

1 tsp ground cinnamon
¼ tsp ground nutmeg
1 tbsp cornstarch

For the crisp topping

1 cup old-fashioned rolled oats
½ cup all-purpose flour
½ cup packed light brown sugar
Chef's tip
Use the same volume. Brown-sugar replacements vary in moisture, spread, and browning, so follow the package's baking guidance and start checking a few minutes early.
½ tsp ground cinnamon
¼ tsp salt
6 tbsp unsalted butter, cold and cut into small cubes

For serving

vanilla ice cream or whipped cream, for serving (optional)

Instructions

1
In a large bowl, toss the sliced apples with the granulated sugar, lemon juice, ground cinnamon, nutmeg, and cornstarch until every slice is evenly coated. Transfer the apple mixture to the insert of a 6-quart slow cooker and spread into an even layer.
2
In a medium bowl, combine the rolled oats, flour, brown sugar, cinnamon, and salt. Add the cold butter cubes and work them in with your fingertips, pressing and rubbing until the mixture resembles coarse, clumpy crumbs with pea-sized pieces of butter throughout. Scatter the topping evenly over the apples — do not press it down.
