Make the topping and set aside: Mix 1/2 cup bread crumbs and the butter and reserve. Preheat oven to 370 degrees.
Mix the lemon rind and lemon juice with the cherries. Put a layer of cherries on the bottom of an oven-safe casserole. Top with a layer of sugar, then a layer of bread crumbs. Repeat using the rest of the ingredients.
Sprinkle the topping mix evenly over the top, cover, and bake for about 30 minutes. Remove the lid, and place back in the oven and bake for another 15 to 20 minutes until browned and bubbly.
