Make a nice beef or lamb stew as you normally would. Keep the sauce a little on the thick side. Grate a couple of baker potatoes and grate them using the large side. Rinse these potatoes off once, squeeze them dry and then add some chopped garlic, chopped parsley, salt and pepper and a little melted butter. Put these potatoes on top of the stew and bake in the oven.
You can also use sliced potatoes as in the boulangere potatoes which in a way might be better because the grated potatoes can get soggy if you are not careful.
