01 - Preheat the oven to 350°F. Lightly grease an 8-inch square baking dish.
02 - In a large bowl, combine apple slices with lemon juice, brown sugar, cinnamon, nutmeg, and a pinch of salt. Toss well and spread the apple mixture evenly in the prepared baking dish.
03 - In a separate small bowl, mix ricotta cheese, honey, vanilla extract, and lemon zest until smooth. Dollop the mixture over the apples and gently spread to cover most of the fruit.
04 - Combine granola, melted butter, and maple syrup in another bowl. Stir until the granola is thoroughly coated.
05 - Sprinkle the coated granola evenly over the ricotta layer. Bake for 30 to 35 minutes, until the granola is golden brown and apples are tender.
06 - Allow to cool for at least 10 minutes before serving. Serve warm or at room temperature.
