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.
Preheat oven to 400 degrees. Lightly grease a 13 x 9 inch baking dish. Spread the mixture evenly in the baking dish. Bake for about 40 minutes, or until firm. Don’t over-bake.
While the chicken souffle is baking, make the herb sauce.
Make the creamy herb sauce:
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 ½ 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. You can serve the sauce on the side, or drizzle on each serving. Top with fresh herbs!
