There’s no reason why a vegetable lasagna made with the classic trio of eggplant, zucchini, and summer squash should be any less satisfying than a meat-based casserole, especially when the produce is in season and locally grown.
But we’ve rarely cooked one that we’ve been moved to make again. Some versions look tempting enough with a topcoat of bubbly cheese and thick tomato gravy, but cutting out a square of it invariably reveals trouble at the core. Often placed between the pasta sheets raw, the zucchini and squash turn out steamy and limp, flooding the dish with their juices or, in some instances, undercooked and crunchy.
