For the Waldviertler potato casserole, press the cooked potatoes hot, mix the diced cooked ham with the other ingredients and pour into a buttered casserole pan.(If the whole thing is too firm, add a little more cream). Add butter flakes on top of the casserole and bake at 180 degrees until the edges are crispy ( about 1 hour). Remains a little soft in the middle.
When serving, cut the Waldviertel potato casserole into square pieces.
Waldviertel potato casserole is served with Chinese cabbage, green salad, cucumber salad or red beet salad.
