Place the peeled, cored apples in the slow cooker without chopping them into pieces. Drizzle the lemon juice over the apples.
10-12 medium apples, 1/2 lemon
Pour in the water, then sprinkle the brown sugar and cinnamon over the apples. Do not stir. Cover with the lid.
1 cup water, 1/2 cup brown sugar, 1 tbsp ground cinnamon
Cook on high for about 5 hours, until the apples are very soft and collapse easily when pressed with a potato masher. If any apples remain firm, cover and continue cooking until tender.
Mash directly in the slow cooker, stirring to distribute the brown sugar and cinnamon. Mash lightly for chunky applesauce or more thoroughly for a smoother texture.
Taste and adjust the sweetness or cinnamon if desired. Serve warm or refrigerate to enjoy chilled.
