Preheat oven to 350 degrees. Lightly butter the baking dish.
Peel, core, and slice the apples into a large bowl. Take care to make sure slices are similar in size.
Mix in one half-cup of the sugar, the spices, and the lemon juice.
Pour the apples into the greased casserole dish.
Combine the flour and the butter until crumbly, using a pastry cutter. (If you don't have a pastry cutter, use two butter knifes or just work the dough (quickly, so butter doesn't melt!) with your fingers.
Spread the crumbled butter and flour mixture over the apples. Bake in a 350-degree (preheated) oven for about 45 minutes, until the apples are tender, the topping is brown, and you can smell the delicious apples and their spices!
