1 large butternut squash - halved lengthwise, peeled and seeded
2 teaspoons butter
salt and ground black pepper to taste
1/2 teaspoon allspice
1/2 teaspoon ground nutmeg
2 teaspoons ground cinnamon
1/2 cup Parmesan cheese
50 wonton wrappers
1 teaspoon egg white, lightly beaten
1/4 cup unsalted butter
1/4 cup chopped fresh sage leaves
salt and freshly ground black pepper to taste
Preheat oven to 350 degrees F (175 degrees C).
Place the squash cut side up on a baking sheet. Place 1 tablespoon butter in the hollow of each half. Sprinkle with salt and pepper to taste. Cover the squash with a sheet of aluminum foil tucking in the edges.
Bake squash in preheated oven until tender and easily pierced with a fork, 45 to 65 minutes.
Scoop the cooked squash into a bowl, and mash until smooth. Mix in the allspice, nutmeg, cinnamon, and Parmesan cheese until well blended. Season to taste with salt and pepper.
Fill a deep pot with lightly salted water and bring to a boil.
To make the ravioli, place a wonton wrapper on a clean, flat surface. Brush edges with the egg white. Place about 1 tablespoon of the squash mixture in the middle of the wonton. Cover with a second wonton wrapper. Repeat with remaining wonton wrappers and squash mixture until all have been used.
Drop the ravioli into the boiling water, and cook for 3 to 5 minutes, or until tender. Remove, drain, and keep warm until sauce is prepared.
To make the sauce, melt the butter in a skillet over medium heat. Stir in the sage. Continue to cook and stir until the sage is crispy but not browned. Add salt and pepper to taste. Place raviolis on serving plates, and drizzle with sauce.
