For the vegetables:
1 butternut squash, peeled and cut into 1/2-inch cubes
2 tablespoons extra-virgin olive oil
1 sweet yellow onion, halved and sliced thin
1 tsp garlic powder
1 tsp salt
1/8 tsp ground red pepper
For the bechamel:
2 tablespoons salted butter
10 fresh sage leaves, finely chopped
1/4 cup all-purpose flour
4 cups whole milk
¼ tsp of freshly grated nutmeg
½ tsp salt
For the lasagna:
Unsalted butter, for the baking dish
2 cups grated low-moisture mozzarella cheese (about 8 ounces)
2 cups grated parmesan cheese (about 8 ounces)
1 tablespoon all-purpose flour
9 no-boil lasagna noodles
Make the vegetables: Preheat the oven to 425 degrees F. Toss the squash and
onions with olive oil on a baking sheet. Season with salt, garlic powder and
red pepper. Roast, rotating the baking sheet once, until the vegetables are tender,
18 to 20 minutes. Smash squash with a fork until evenly mashed and set aside.
Reduce the oven temperature to 350 degrees F.
Meanwhile, make the bechamel: Melt the butter in a medium saucepan over medium
heat. Add the sage and cook 1 minute. Whisk in the flour until smooth; cook,
whisking, until the flour is lightly golden but not brown, about 2 minutes.
Gradually whisk in the milk until smooth. Bring to a boil, then reduce the heat
to medium low and simmer, stirring occasionally, until thickened, about 5
minutes. Stir in the nutmeg and salt.
Assemble the lasagna: Butter a 9-by-13-inch baking dish. Toss the cheeses and
the flour in a bowl; set aside 1/2 cup for topping. Evenly coat the bottom of
the dish with 1/2 cup of the bechamel. Lay 3 noodles side by side on top. Cover
with one-third of the remaining bechamel. Sprinkle with half of the remaining
cheese mixture, then top with half of the vegetable mixture, spreading evenly.
Arrange 3 more noodles on top and repeat the layers (bechamel, cheese,
vegetables). Top with the remaining 3 noodles, then cover with the remaining
bechamel; sprinkle with the reserved 1/2 cup cheese.
Loosely cover the dish with foil and bake until bubbly, about 45 minutes. Turn
on the broiler. Uncover the lasagna and broil until browned, about 2 minutes.
Let stand 15 minutes before serving.
