Giada'S Lasagna Rolls

Directions

1. 1
   Preheat the oven to 450°F.
2. 2
   Whisk the ricotta, spinach, 1 cup Parmesan, prosciutto, egg, salt, and pepper in a medium bowl to blend.
3. 3
   Add a tablespoon or 2 of oil to a large pot of boiling salted water. Boil the noodles until just tender but still firm to bite. Drain. Arrange the noodles in a single layer on a baking sheet to prevent them from sticking.
4. 4
   Butter a 13x9x2-inch glass baking dish. Pour sauce over the bottom of the prepared dish. Lay out 4 lasagna noodles on a work surface, then spread about 3 tablespoons of ricotta mixture evenly over each noodle. Starting at 1 end, roll each noodle like a jelly roll.
5. 5
   Lay the lasagna rolls seam side down, without touching, atop the sauce in the dish.
6. 6
   Repeat with the remaining noodles and ricotta mixture. Spoon 1 cup of sauce over the lasagna rolls.
7. 7
   Sprinkle the mozzarella and remaining 2 tablespoons of Parmesan over the lasagna rolls.
8. 8
   Cover tightly with foil. Bake until heated through and the sauce bubbles, about 20 minutes.
9. 9
   Uncover and bake until the cheese on top becomes golden, about 15 minutes longer. Let stand for 10 minutes.
