6 large Granny Smith apples, peeled, cored, and sliced
1/2 cup granulated sugar
1 tablespoon ground cinnamon
1 tablespoon lemon juice
1 cup old-fashioned rolled oats
1 cup all-purpose flour
1 cup packed light brown sugar
1/2 cup unsalted butter
1/2 teaspoon salt
1/2 cup chopped pecans (optional)
Instructions
Preheat your oven to 375°F (190°C). Lightly grease a 9×9 inch baking dish or a similar sized oven-safe skillet with butter or non-stick cooking spray.
Place the butter in a small saucepan over medium heat. Melt the butter, then continue cooking while whisking constantly. Watch for small brown bits to form at the bottom and wait for a nutty aroma. Once the butter is a deep golden brown, remove it from the heat immediately so it doesn’t burn.
In a large mixing bowl, toss the sliced apples with the granulated sugar, lemon juice, and half of the cinnamon. Ensure every slice is evenly coated. Pour the apple mixture into your prepared baking dish and spread them out evenly.
In another bowl, whisk together the oats, flour, brown sugar, salt, pecans, and the remaining cinnamon. Pour the slightly cooled brown butter over the dry ingredients. Stir with a fork until the mixture is crumbly and no dry flour remains.
Sprinkle the crumble topping evenly over the apples in the baking dish. Place the dish in the center of the oven and bake for 40 to 45 minutes. The topping should be a dark golden brown and the apple juices should be bubbling around the edges.
Remove the crisp from the oven and let it sit for at least 10 to 15 minutes before serving. This allows the juices to thicken slightly, making it easier to scoop.
