Winter Squash Soup w/Gruyere Cheese Croutons

I posted this recipe on the personal blog earlier, but I finally got around to making it today. I only had one acorn squash from the Produce Box, but I had plenty of butternut to make up the difference in amounts. Other slight changes I did are listed below, in with the recipe.

Winter Squash Soup with Gruyère Croutons Bon Appétit | December 1996

Ingredients
Soup
1/4 cup ( 1/2 stick) butter
1 large onion, finely chopped
4 large garlic cloves, chopped
3 14 1/2-ounce cans low-salt chicken broth [I used vegetable broth]
4 cups 1-inch pieces peeled butternut squash (about 1 1/2 pounds)
4 cups 1-inch pieces peeled acorn squash (about 1 1/2 pounds)
1 1/4 teaspoons minced fresh thyme
1 1/4 teaspoons minced fresh sage [I couldn't find fresh so I used some I bought in a jar]
1 tsp ginger [I added this to the recipe]

1/4 cup whipping cream
2 teaspoons sugar

Croutons
2 tablespoons (1/4 stick) butter
24 1/4-inch-thick baguette bread slices
1 cup grated Gruyère cheese
1 teaspoon minced fresh thyme
1 teaspoon minced fresh sage
Preparation

For soup:
Melt butter in large pot over medium heat. Add onion and garlic and sauté until tender, about 10 minutes. Add broth, all squash and herbs; bring to boil. Reduce heat, cover and simmer until squash is very tender, about 20 minutes.

Working in batches, puree soup in blender. Return soup to same pot. Stir in cream and sugar; bring to simmer. Season with salt and pepper. (Can be made 1 day ahead. Chill. Rewarm over medium heat before serving.)

For croutons:
Preheat broiler. Butter 1 side of each bread slice. Arrange bread, buttered side up, on baking sheet. Broil until golden, about 1 minute. Turn over. Sprinkle cheese, then thyme and sage over. Sprinkle with salt and pepper. Broil until cheese melts, about 1 minute. Ladle soup into bowls. Top each with croutons and serve.
