Step 1

Pour contents of the butternut squash package into a 2-quart microwave-safe baking dish with a lid. Add 2 tablespoons water. Cover. Microwave on 100 percent power (high) for 3 minutes. Stir. Microwave on 100 percent power (high) for 3 minutes more. Stir again. Microwave on 100 percent power (high) about 2 minutes more or until squash is very tender. Using a pastry blender or potato masher, mash squash.

Step 2

Meanwhile, in a heavy medium saucepan cook onion in hot butter until tender, stirring frequently.

Step 3

In a food processor or blender combine cooked onions, mashed squash, broth, evaporated milk, brown sugar, salt, the 1/2 teaspoon ground nutmeg, and the white pepper. Cover and process or blend until smooth. Return soup to the saucepan. Cook and stir over medium-high heat until heated through. If desired, garnish with thyme and freshly grated nutmeg.
