Boil the broccoli florets in water for about 5 minutes. Remove from the water and cook the pasta in the same water for about 5 minutes. Then take out the pasta and dissolve the bouillon cube in the same water. Put the pasta and broccoli in a baking dish. Fill half of the baking dish with bouillon, the other half with cream, until the pasta and broccoli mixture is almost covered. Stir in half of the grated cheese and season with pepper, nutmeg and a little salt.
Put the whole thing in the oven for about 20 minutes at 220 ° C. Occasionally stir the noodles otherwise the top will be dry. After 20 minutes, sprinkle the rest of the cheese on top and switch to top / bottom heat until the casserole is browned.
