Prep the Apples: Start by peeling and slicing 6 large apples. Granny Smith apples will give a delightful tartness, while Golden Delicious offers sweetness. Place the sliced apples in the slow cooker.
Combine the Dry Ingredients: In a separate bowl, mix together 1 cup packed brown sugar, 1 tsp ground cinnamon, ½ tsp ground nutmeg, and a pinch of salt. Sprinkle this mixture evenly over the sliced apples in the slow cooker.
Prepare the Sauce: In another bowl, whisk together ½ cup melted unsalted butter, 1 tbsp cornstarch, 1 tbsp lemon juice, and ½ cup apple juice or cider. Pour this mixture over the apples in the slow cooker, ensuring they are well coated.
Cook the Apples: Cover the slow cooker and set it to low heat. Cook for 3-4 hours until the apples are tender. You can occasionally stir the mixture gently to help combine the flavors, but it’s not necessary.
Serve: Once cooked, gently stir the apples to combine, and serve warm. These can be enjoyed on their own or paired with vanilla ice cream for a delightful dessert.
