This is a perfect time of year for roasted vegetables. Making lasagna with them can be quite a process. But there's a payoff in the end: lots of food, either for a crowd or to freeze for later.
This particular lasagna is time consuming but not difficult. All it really takes is a little knife skill to cut eggplant and zucchini into thin slices. These are layered with a mix of roasted red onion and goat cheese, seasoned with one of my favorite herbs, marjoram, which we just happen to have growing in abundance outside our front door.
This recipe will fill a standard Pyrex baking dish, meaning a dozen adult servings. You'll need two pounds of eggplant, two pounds of zucchini, three medium red onions, six ounces of goat cheese, three cups of marinara sauce and lasagna noodles. (I used no-boil noodles from Whole Foods, but don't be shy about making your own.)
Heat the oven to 500 degrees. Trim and peel the eggplant, then slice it lengthwise into 1/4-inch pieces. Salt them generously on both sides and place in a colander to drain for 30 minutes. Squeeze them dry between sheets of paper towel.
Lay the eggplant slices on a baking sheet, brush them on both sides with extra-virgin olive oil and season with pepper. Place them in the oven and cook until they are starting to brown. Slice the zucchini lengthwise into 1/4-inch pieces, brush with olive oil and season with salt and pepper. Roast them also until starting to brown. Peel the onions and cut them into thick rings. Toss them with olive oil and season with salt and pepper. Spread them on a baking sheet and roast as you have the eggplant and zucchini.
When the onions are cool enough to handle, chop them roughly and mix with the goat cheese. Spread some marinara sauce on the bottom of your lasagna pan and cover with lasagna noodles. Layer some eggplant and zucchini over the noodles, dot with the onion-goat cheese mix and pour another layer of marinara sauce. Season with chopped fresh marjoram.
Add more layers until you've run out of ingredients or filled your pan, whichever comes first. Lower the oven to 375 degrees and put in your lasagna--it's a good idea to have a baking sheet underneath to catch any drippings. Bake until the the noodles are completely cooked through and the vegetables are bubbling,l about one hour. Before pulling it from the oven, grate some Pecorino cheese generously over the top and cook a few minutes more.
Serve this with a fresh fall salad and your favorite red wine.
