Ingredients
- 1 (15-ounce) container whole milk ricotta cheese
- 1 (10-ounce) package frozen chopped spinach, thawed, squeezed dry
- 1 cup plus 2 tablespoons grated Parmesan
- 3 ounces thinly sliced prosciutto, chopped
- 1 large egg, beaten to blend
- 3/4 teaspoon salt, plus more for salting water
- 1/2 teaspoon freshly ground black pepper
- 1 to 2 tablespoons olive oil
- 12 uncooked lasagna noodles
- 2 cups marinara sauce
- 1 cup shredded mozzarella (about 4 ounces)
- 1 jar (28 oz) marinara sauce
Preparation
Step 1
Preheat the oven to 375 degrees F.
Whisk the ricotta, spinach, 1 cup Parmesan, prosciutto, egg, salt, and pepper in a medium bowl to blend.
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.
Butter a 13-by-9-by-2-inch glass baking dish. Pour the sauce over the bottom of the prepared dish. Lay out 4 lasagna noodles on a work surface, then spread a large spoonful (about 3 tablespoons worth) of ricotta mixture evenly over each noodle. Starting at 1 end, roll each noodle like a jelly roll. Lay the lasagna rolls seam side down, without touching, atop the sauce in the dish. Repeat with the remaining noodles and ricotta mixture. Spoon 1 cup of marinara sauce over the lasagna rolls. Sprinkle the mozzarella and remaining 2 tablespoons of Parmesan over the lasagna rolls. Bake until heated through and the sauce bubbles, about 20 minutes. Let stand for 10 minutes.
