Preparation

  1. Bring the 3 quarts of water to a boil in a large pot and add the penne. Cook for approximately 8 minutes, until just tender, and drain. Rinse briefly under cool water to stop the cooking if you don’t intend to assemble the dish immediately.
  2. Bring 1/3 cup of water to a boil in a large skillet. Add the broccoli pieces, cover, return to the boil and cook for 3 minutes, or until most of the water has evaporated. Add the mushrooms, red pepper, walnuts and olive oil and mix well. Add the spinach, still wet from washing, cover and cook 2 to 3 minutes, or until it is wilted. (At this point, the vegetables can be combined with the warm pasta, seasoned with salt and pepper and served with a little grated Parmesan cheese as a side dish.) For the gratin, set the vegetables aside while you make the sauce.
  3. For the bechamel sauce, melt the butter in a saucepan. Add the flour, mixing it in well with a whisk. Stir in the milk and bring the mixture to a boil, stirring with a whisk (especially around the edges where it might have a tendency to burn) until lightly thickened. Add the cream and salt and pepper, then return to the boil. Set aside.
  4. When ready to serve, mix together the vegetables, pasta and bechamel sauce and stir in the Swiss cheese. Spread the mixture into a 10-to-12-cup gratin dish. If the ingredients are still hot, place the dish under a hot broiler for 5 minutes, until the top is lightly browned. If some of the ingredients are lukewarm or cool, heat the gratin for about 10 minutes in a 400-degree oven until bubbling hot, then brown for 5 minutes under the broiler. If the mixture is cool throughout, place the gratin in a 400-degree oven for approximately 15 to 20 minutes, then place under the broiler for 5 minutes. Serve immediately.
