Combine the pumpkin, chicken, butter, flour, ricotta cheese, parmesan cheese, green onions, garlic, and fresh basil in a large bowl. Add in the eggs; season with salt and pepper to taste and mix well.
Lightly grease a 13 x 9 inch baking dish. Spread the mixture evenly in the baking dish. Bake at 400 degrees F for about 40 minutes, or until firm. Don’t over-bake.
While the chicken souffle is baking, heat the oil in a small saucepan, adding the garlic. Stir and cook until the garlic is lightly browned. Add the wine and stock; reduce the heat and simmer, until the sauce is reduced to about 1/2 cup.
Add the cream and chopped herbs; stir and season to taste with salt and white pepper.
Cut the chicken souffle into squares, and serve hot with the sauce on the side. Top with fresh herbs!
