Ingredients
- For the sauce:
- 4 tablespoons unsalted butter
- 2 2/3 tablespoons all-purpose flour
- 2 1/2 cups whole milk
- 1/2 teaspoon salt
- 1/4 teaspoon ground black pepper
- Pinch ground nutmeg
- For the lasagna:
- 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
- 1 jar of your favorite marinara sauce (24 oz. size)
- 1 cup shredded mozzarella (about 4 ounces)
Preparation
Step 1
To make the sauce: Melt the butter in a heavy medium saucepan over medium-low heat. Add the flour and whisk for 3 minutes. Whisk in the milk. Increase the heat to medium-high. Whisk the sauce until it comes to a simmer and is thick and smooth, about 3 minutes. Whisk the salt, pepper, and nutmeg into the béchamel sauce. The sauce will continue to thicken as it stands.
Preheat the oven to 450 degrees F.
To make the lasagna: Stir 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 béchamel 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. Lay the lasagna rolls seam side down, without touching (not sure why she stipulates this, ours did just fine snug up against one another), atop the béchamel sauce in the dish. Repeat with the remaining noodles and ricotta mixture. Pour jar of marinara sauce over the lasagna rolls. Sprinkle the mozzarella and remaining 2 tablespoons of Parmesan over the lasagna rolls. Cover tightly with foil. Bake until heated through and the sauce bubbles, about 20 minutes. Uncover and bake until the cheese on top becomes golden, about 15 minutes longer. Let stand for 10 minutes.
Notes:
The parts that we did differently from Giada’s original recipe were to double – yes, double – the béchamel sauce and to up the marinara to a whole jar, or 24 oz. The reason we did this is because the first time I made it strictly according to the original directions, the lasagna was a little dry. I’ve found this to be a common occurrence when making anything of Giada’s that is baked. I kind of take it as bible now that if I make any of her baked pasta recipes, I’ll up the moisture levels to compensate. Plus, doubling the béchamel sauce is also a little bit because I like it so darn much. I admit it. I’m a béchamel pig.
You don’t have to double the béchamel if you prefer not to, but be aware the directions above are the doubled directions. You’ll need to cut those in half, or click the link at the beginning of the recipe to go to the original.
You can make this all the way up to the last step and freeze it if you need to make it ahead of time. Would make a good dish for a gift to someone for just this reason. Whenever my mom does this, she usually lets it thaw about halfway before putting in the oven. Just bake until the top gets nice and brown, like usual.
