Golden Winter Soup

It is a crappy rainy day here in Boise so Matthew and I wanted something hot. I was thinking of potato soup but we were missing some of the ingredients for my regular recipe so I came across this recipe from cooking light. It was delicious and had an awesome smooth texture. I didn't have any half and half so I substituted 1/2 c sour cream and 1/2 c milk. I also added a little fresh parsley--delish! Serve with Holly's Red Lobster Cheddar Bay Biscuits.

2 tablespoons butter
5 cups (1/2-inch) cubed peeled butternut squash (about 1 1/2 pounds)
2 cups (1/2-inch) cubed peeled russet potato (about 12 ounces)
1 teaspoon kosher salt
1/2 teaspoon freshly ground black pepper
2 cups sliced leek (about 2 medium)
4 cups fat-free, less-sodium chicken broth
1 cup half-and-half
12 ounces baguette, cut into 16 slices
3/4 cup (3 ounces) shredded Gruyère cheese
3 tablespoons chopped chives
Freshly ground black pepper (optional)

Melt butter in a large Dutch oven over medium-high heat. Add squash, potato, salt, and pepper to pan; sauté 3 minutes. Add leek; sauté 1 minute. Stir in broth; bring to a boil. Reduce heat, and simmer 20 minutes or until potato is tender, stirring occasionally. Place half of potato mixture in a blender. Remove center piece of blender lid (to allow steam to escape); secure blender lid on blender. Place a clean towel over opening in blender lid (to avoid splatters). Blend until smooth. Pour into a large bowl. Repeat procedure with remaining potato mixture. Stir in half-and-half. Serve.
