This dish is perfect for fall, it is warm, creamy and colorful. It is also vegetarian for those veggie heads in your life! I found this recipe in Pippa Middleton's "Celebrate" book.
For lasagna:
1 large onion, diced
2 1/2 lbs butternut squash, peeled, seeded and sliced into 1/8" thick pieces
1 large bunch of sage leaves, half chopped, half whole-leaf
4 large garlic cloves, chopped
1 lb fresh spinach
1 tsp nutmeg
1 tsp salt
1 tsp pepper
1 lb lasagna noodles
16oz shredded mozzarella
For bechemel sauce:
1 stick unsalted butter
1 cup flour
3 cups whole milk
1 cup Parmesan cheese, grated
Preheat the oven to 400 degrees F. Drizzle some olive oil into a baking dish and add the onion, butternut squash, chopped sage and garlic then roast in the oven for 15-20 minutes.
To make the bechamel sauce, melt the butter in a medium saucepan, then add the flour until you have a paste and cook for 1-2 minutes. Slowly add the milk, constantly stirring until it forms a thick sauce. Add the Parmesan and stir until melted. Remove from heat.
In a separate pan, add the nutmeg, salt, pepper and spinach. Cook for a couple of minutes until the spinach is wilted. Squeeze out excess water.
Bring pot of salted water to a boil and cook the lasagna noodles. Oil the bottom of a lasagna pan and layer noodles, squash mixture, bechemel and a light layer of mozzarella. Repeat. On the top of the last layer of noodles, put a good layer of mozzarella and the whole sage leaves. Bake in oven (at 400 degrees F) for 25 minutes until the mozzarella on top is all bubbly and gooey.
