Lasagna with Slow-Roasted Tomato Sauce
Slow-roasting the tomatoes gives the tomato sauce for this lasagna recipe an intense depth of flavor--which is then enhanced by the umami in onions, Parmesan and spinach. The lasagna noodles are layered into the lasagna uncooked; the moisture from the fresh spinach cooks them perfectly as the lasagna bakes in the oven.
