Classic Apple Crisp with Oat Streusel

1.Preheat your oven to 190°C (375°F). Lightly grease an 8x8 inch (or similar 2-quart) baking dish.

2.Prepare the apple filling: In a large bowl, combine the sliced apples, 1/4 cup granulated sugar, 1 tbsp flour, 1 tsp cinnamon, lemon juice, and salt. Toss gently until the apples are evenly coated. Pour the mixture into the prepared baking dish.

3.Prepare the streusel topping: In a separate medium bowl, whisk together the 1 cup flour, rolled oats, brown sugar, 1/4 cup granulated sugar, 1/2 tsp cinnamon, and nutmeg.

4.Cut in the cold butter cubes using a pastry blender, two knives, or your fingertips. Work the butter into the dry ingredients until the mixture resembles coarse, moist crumbs. Avoid overmixing; some pea-sized clumps of butter are desirable.

5.Sprinkle the streusel topping evenly over the apple filling in the baking dish, ensuring the apples are mostly covered.

6.Bake for 40 to 50 minutes, or until the topping is deeply golden brown and the apple filling is bubbling vigorously around the edges and tender when pierced with a fork.

7.Remove the crisp from the oven and let it cool on a wire rack for at least 15 minutes before serving. This allows the filling to set slightly. Serve warm, optionally topped with vanilla ice cream or whipped cream.
