   Preheat oven to 400F.

   Whisk together ricotta, eggs, 1/2 teaspoon salt, and 1/4 teaspoon pepper.

   Spread a thin layer of tomato sauce in the bottom of a 9-by-13-inch glass baking dish.
5. 5
   Arrange 4 noodles on top.
6. 6
   Spread one-third of the ricotta mixture over noodles, followed by one-third of the remaining tomato sauce; sprinkle with one-third of the fontina cheese.
7. 7
