Apple crumble is delicious and simple to make on a sheet pan. It has plenty of crumbs on top, sliced baking apples, rolled oats and sweet flavor of brown sugar and cinnamon.
7 medium baking apples, about 3 lb. (Gala or Fuji)
1 T. freshly squeezed lemon juice
1 1/2 c. packed light brown sugar, divided
2 sticks unsalted butter, melted, divided
2 t. ground cinnamon, divided
1 1/8 t. Kosher salt, divided
2 c. old-fashioned rolled oats
1 1/2 c. all-purpose flour
vanilla ice cream, for serving, optional
Position a rack in the center of the oven. Preheat oven to 425 degrees F.
Peel and core the apples; cut into 1/4 inch thick slices. Place apple slices on an 18x13 inch sheet pan. Toss with the lemon juice, 1/4 c. brown sugar, 2 T. melted butter, 1 t. cinnamon, and 1/8 t. salt.
Spread the apples evenly on the sheet pan; cover with aluminum foil. Bake until the apples have softened and released some liquid, about 20 minutes.
Meanwhile, combine the rolled oats, flour, remaining 1 1/4 c. brown sugar, 1 t. cinnamon, and 1 t. salt together in a large bowl, breaking up any lumps with a fork. Add the remaining melted butter to the oat mixture, stirring with a fork until moistened and crumbly.
Carefully uncover the sheet pan. Scatter the oat crumble evenly over the top.
Bake uncovered until the top is crisp and golden brown and juices are bubbly, about 15 minutes.
Serve with vanilla ice cream, if desired.
10-12 servings.
