One day before you want to serve the lasagna, line a sieve with cheesecloth, set it over a bowl, empty the Ricotta into the sieve
and drain overnight in the refrigerator.
When ready to assemble and bake the lasagna, preheat the oven to 375° F. Chop the vegetables into ½-inch chunks.
Heat 4 tablespoons of olive oil in a large non-stick pan. Sauté the chopped vegetables with the fresh herbs and the fennel seeds (if
using) until the vegetables are soft, about 10 to 20 minutes. Add more olive oil if the vegetables seem to be drying out. Season with
salt and pepper. If you use any frozen vegetables, add them halfway through the cooking time. Set aside. You should have 4 to 6
cups of vegetables.
On the bottom of a 13 x 9 x 3-inch baking dish, spread 1 cup of tomato sauce. Cover with a layer of lasagna sheets, leaving ½-inch
gap between the sides of the dish and the sheets.
Spread half the vegetables over the sheets and cover with 1½ cups of tomato sauce. Top the sauce with 1 cup of Mozzarella and ¼
cup Parmigiano Reggiano. Cover with a second layer of lasagna sheets.
Beat the eggs in a bowl, season with pepper and salt, and stir in the Ricotta. Spread the mixture over the lasagna sheets. Top with
another layer of lasagna sheets.
Layer the rest of the vegetables, another 1½ cup of sauce, the rest of the Mozzarella and a sprinkling of more Parmigiano
Reggiano. Top with the last layer of lasagna sheets.
Stir together the last of the tomato sauce and the heavy cream. Pour over the top layer of lasagna sheets and sprinkle with the
rest of the Parmigiano Reggiano. Cover with foil and bake for 40 minutes. Remove the cover and bake 15 minutes more. Let sit at
least 15 minutes before serving.
