Creating this amazing Blueberry Crisp is incredibly simple. Just follow these steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Prepare the Blueberries: In a large mixing bowl, combine fresh blueberries, granulated sugar, lemon juice, and vanilla extract. Stir gently to coat the blueberries evenly.
3. Transfer to Baking Dish: Pour the blueberry mixture into a greased 9×13-inch baking dish, spreading it evenly across the bottom.
4. Mix the Topping: In a separate bowl, mix rolled oats, all-purpose flour, light brown sugar, ground cinnamon, and salt together.
5. Add Butter: Pour in the melted butter and mix until all ingredients are well combined and crumbly.
6. Top the Blueberries: Sprinkle the oat mixture evenly over the blueberries.
7. Bake: Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the topping is golden brown and the blueberries are bubbling.
8. Cool: Once done, remove the dish from the oven and allow it to cool for about 10-15 minutes before serving.
