Instructions
- Step 1: Preheat your oven to 350°F. In a large mixing bowl, toss 5 cups peeled and sliced tart apples with 1/3 cup granulated sugar, 2 tsp lemon juice, and 1 tsp ground cinnamon until the apples are well coated.

- Step 5: Sprinkle the oat topping evenly over the apple mixture in the baking dish.
- Step 6: Bake uncovered for 45 minutes until the topping is golden brown and the apple filling is bubbling around the edges.
