Ingredients

For the squash:

Directions

2 large butternut squash, about 3 to 5 pounds

3 tablespoons extra-virgin olive oil

1 tablespoon finely chopped fresh sage leaves

1 tablespoon Fennel and Cinnamon Spice Blend, recipe follows

2 teaspoons salt

1/2 teaspoon freshly ground black pepper

1 teaspoon freshly grated nutmeg

2 cups ricotta cheese (or a 15-ounce container)

1 cup freshly grated Parmesan

2 large eggs

1 pound dried lasagna sheets (about 24 sheets), each 6 1/2 by 3 inches

Extra-virgin olive oil

For the sauce:

2 quarts whole milk

6 tablespoons unsalted butter

1 tablespoon sage, minced

2 teaspoons minced garlic

1/2 cup all-purpose flour

2 teaspoons salt

Freshly ground black pepper

1/2 teaspoon freshly grated nutmeg

To assemble the lasagna:

Butter, for dish

1 pound mozzarella, grated

1 cup freshly grated Parmesan

Preheat the oven to 400 degrees F.

Using a vegetable peeler, remove the squash's hard shell. Trim about 1/2-inch off the top and bottom ends so you can set each section of the squash flat on a cutting board. Cut the squash in half lengthwise. Scoop the seeds out with a spoon, and coarsely chop the squash into 1/2-inch chunks. Line a baking sheet with aluminum foil. In a bowl, toss the squash with the oil, sage, spice blend, and 1 teaspoon salt and fresh ground pepper. Spread the squash in a single layer on the baking sheet. Roast the squash in the oven until very soft and beginning to brown, 40 to 50 minutes, stirring once or twice. Remove the squash from the oven and puree in a food processor with fresh nutmeg.

In a large bowl, mix the squash puree, ricotta, Parmesan, eggs, 1 teaspoon salt, and 1/2 teaspoon pepper. Cover and refrigerate the mixture until ready to use.

In a large pot of boiling, salted water, cook the lasagna sheets until al dente. Drain the sheets and spread them on a baking sheet. Drizzle them lightly with oil and set aside.

Prepare the sauce: In a large saucepan, bring the milk to a slow simmer over medium heat. In a large pot, melt the butter over medium-low heat. Add the sage and garlic to the butter, cook for 30 seconds, then add the flour and stir. Add about 3 cups of the milk, and whisk vigorously to prevent lumps. Bring to a boil, while whisking continuously. Add the remaining milk and whisk again. Add the salt, pepper, and nutmeg. Adjust the heat to low to maintain a slow simmer, and cook until the sauce coats the back of a spoon, about 5 minutes, whisking frequently. Remove the saucepan from the heat. Makes about 8 cups.

Preheat the oven to 375 degrees F.

Butter a 9 by 13-inch baking dish. Spoon a ladle of bechamel into the dish and spread to coat the bottom. Place a single layer of lasagna sheets on top of the bechamel. Spread some of the squash mixture evenly over the lasagna sheets and sprinkle about 2 tablespoons of mozzarella cheese and 1 tablespoon of grated Parmesan on top. Repeat this step until all ingredients are used, starting with 2 to 3 ladles of bechamel for each layer. Keep building the layers until the pan is full to about 1/4-inch from the top. Finish with cheese and sauce directly over the noodles. Bake in the middle of the oven for about 1 hour. Remove the cover, and continue cooking for another 15 minutes until golden brown and bubbling. Allow lasagna to rest before slicing. Serve warm.

Fennel and Cinnamon Spice Blend:

3 tablespoons fennel seeds

2 teaspoons ground cinnamon

Salt

Grind fennel with mortar and pestle. Add the cinnamon and salt and continue grinding. Or grind in spice grinder for a rough grind.

Level:

Intermediate

Serves:

8 to 10 servings

Ingredients

• 1 tablespoon olive oil
• 1 (1 1/2 to 2-pound) butternut squash, peeled, seeded, and cut into 1-inch cubes
• Salt and freshly ground black pepper
• 1/2 cup water
• 3 amaretti cookies, crumbled
• 1/4 cup butter
• 1/4 cup all-purpose flour
• 3 1/2 cups whole milk
• Pinch nutmeg
• 3/4 cup (lightly packed) fresh basil leaves
• 12 no-boil lasagna noodles
• 2 1/2 cups shredded whole-milk mozzarella cheese
• 1/3 cup grated Parmesan

Directions

Heat the oil in a heavy large skillet over medium-high heat. Add the squash and toss to coat. Sprinkle with salt and pepper. Pour the water into the skillet and then cover and simmer over medium heat until the squash is tender, stirring occasionally, about 20 minutes. Cool slightly and then transfer the squash to a food processor. Add the amaretti cookies and blend until smooth. Season the squash puree, to taste, with more salt and pepper.

Melt the butter in a heavy medium-size saucepan over medium heat. Add the flour and whisk for 1 minute. Gradually whisk in the milk. Bring to a boil over medium-high heat. Reduce the heat to medium and simmer until the sauce thickens slightly, whisking often, about 5 minutes. Whisk in the nutmeg. Cool slightly. Transfer half of the sauce to a blender*. Add the basil and blend until smooth. Return the basil sauce to the sauce in the pan and stir to blend. Season the sauce with salt and pepper, to taste.

Position the rack in the center of the oven and preheat to 375 degrees F.

Lightly butter a 13 by 9 by 2-inch glass baking dish. Spread 3/4 cup of the sauce over the prepared baking dish. Arrange 3 lasagna noodles on the bottom of the pan. Spread 1/3 of the squash puree over the noodles. Sprinkle with 1/2 cup of mozzarella cheese. Drizzle 1/2 cup of sauce over the noodles. Repeat layering 3 more times.

Tightly cover the baking dish with foil and bake the lasagna for 40 minutes. Sprinkle the remaining mozzarella and Parmesan cheeses over the lasagna. Continue baking uncovered until the sauce bubbles and the top is golden, 15 minutes longer. Let the lasagna stand for 15 minutes before serving.

*When blending hot liquids: Remove liquid from the heat and allow to cool for at least 5 minutes. Transfer liquid to a blender or food processor and fill it no more than halfway. If using a blender, release one corner of the lid. This prevents the vacuum effect that creates heat explosions. Place a towel over the top of the machine, pulse a few times then process on high speed until smooth.
