I used a mix of varieties of small, tender eggplants and left the skins on. If you use larger ones, peel them first. I don't find salting necessary in this dish because they eggplants are mixed in with so many flavors that they are not bitter at all.
I always seem to have leftover lasagna noodles after assembling a lasagna. I'm not sure why a standard box has more noodles than one really needs to make a standard lasagna. It's just like hotdogs. Why do they sell them in packages of 10 when the buns come in packets of 12 (or is it 8 and 10?). Anyway, if you have leftovers, slice them into strips and toss them with a bit of olive oil and salt. The Italians refer to these odd shapes as "malfatti," meaning poorly made. They taste like any other pasta, though, and could make the start of a nice little lunch.
2 tablespoons olive oil
1 medium onion,
chopped
2 carrots, finely chopped
2 garlic cloves, finely chopped
2
cups diced eggplant
6 cups chopped San Marzano tomatoes (fresh if
you can get them or canned if you can't)
salt and pepper to taste
1
pound lasagna noodles
1 15-ounce container ricotta
1 pound smoked
mozzarella, thinly sliced
about 30 fresh basil leaves
Heat the olive oil over medium heat in a large saute pan. Add the onions, carrots, and garlic and eggplant and cook until they soften, 10-15 minutes. If you are adding fresh tomatoes, add them with their juice. If you use canned tomatoes, drain most of the water, but add enough to make the vegetables slightly saucy. Cook with the tomatoes until the sauce has thickened and the flavors have blended, about 10 minutes. Season with salt and pepper to taste.
While the sauce is cooking, bring a large pot of water to a boil. Add the lasagna noodles and boil them according to the package directions. Drain the noodles and run cold water over them stirring them gently with a wooden spoon or your hands to keep them from sticking.
Spread a thin layer of the sauce in the bottom of a 9-by-13-inch casserole dish. Arrange a single layer of noodles on top of the sauce. Spread a large spoonful of ricotta across each noodle. Top with a few basil leaves. Add a layer of sauce. Repeat with another layer just like that, noodles, ricotta, basil, sauce. You should have enough ricotta for a second layer. For the next layer, use noodles, smoked mozzarella, basil, and sauce. Keep adding layers until you run out of sauce or space in the dish, whichever happens first. For me, this was a total of four layers of noodles. The last layer should have sauce topped by mozzarella.
Bake the lasagna until the cheese is melted, about 30 minutes. If you would like the cheese on the top to brown a bit, remove the lasagna and heat the oven to broil. Put the lasagna back in for a couple of minutes, until the cheese begins to turn a golden brown. Watch very carefully because it will brown quickly and the last thing you need is to burn the lasagna. Remove from the oven immediately. Let it rest for a couple of minutes before you slice and serve.
