Winter Squash, Pine Nut, and Golden Raisin Lasagna

I
 think that this recipe originally came from Weight Watchers, but Joe has made some magically delicious modifications. The result is an unusual and hearty winter dinner that we also like to serve at fall dinner parties.

Serves 4-6.

Ingredients

1/4 cup all-purpose flour
2 1/2 cups fat-free evaporated milk
2 medium garlic clove(s), minced
1/3 cup grated Parmesan cheese
1/8 tsp table salt, or to taste
1/8 tsp black pepper, or to taste
10 oz dry lasagna noodles, cooked al dente (about 12 noodles)
10 oz cooked winter squash, thawed if frozen
1 cup shredded fat-free mozzarella cheese
3/4 cup golden seedless raisins
1/2 cup pine nuts

Instructions

Preheat oven to 350°F.

Place flour in a small saucepan and very gradually whisk in milk and garlic. Warm over low heat, stirring constantly, until sauce simmers and is thickened, about 3 minutes. Remove from heat and stir in Parmesan cheese, salt and pepper.

Spread 1/4 cup of cheese sauce over bottom of a 9 X 13-inch glass or metal pan and cover with 3 lasagna noodles; top with 1/3 of squash and 1/2 cup of cheese sauce. Sprinkle with 1/2 cup of mozzarella cheese and 1/4 cup of raisins.

Cover with 3 more lasagna noodles and spread with 1/3 of remaining squash and 1/2 cup of cheese sauce; sprinkle with 1/4 cup of raisins. Cover with 3 more lasagna noodles and top with remaining squash and raisins; cover with last 3 lasagna noodles, pressing sheets firmly down. Top with remaining cheese sauce; sprinkle with pine nuts and remaining mozzarella cheese.

Cook for 30-45 minutes, until golden brown on top and bubbly.
