Beer and Cheese Soup

At a recent beer and food pairing dinner we went to, there was one course that featured a beer cheese soup and we loved it. So I went on a mission to find a recipe I could make. I'm not sure where I found this recipe, but I tried it last night and it was delicious.

Ingredients:
6 tablespoons butter
1 pound smoked sausage, chopped (Such as Hillshire Farms)
8 large shallots, chopped medium-fine
1/2 cup flour
2 (13 1/2-ounce) cans chicken broth
1 (12-ounce) bottle of beer (some type of ale works best)
2 cups potatoes, peeled and cubed (about 1 large baking potato or 2 small to medium ones)
2 cups milk
1 pound cheddar cheese, grated
1 cup grated parmesan
1/4 teaspoon salt
1 tablespoon paprika
1/2 teaspoon dry mustard
1 teaspoon thyme
1 tablespoon hot sauce
freshly ground pepper to taste
sliced green onions for garnish

Melt the butter in a large stockpot or Dutch oven. Add the sausage and sauté 5 minutes over medium heat, stirring occasionally. Add the chopped shallots and continue to sauté until shallots are translucent. Add the flour and stir to coat. Slowly add the chicken broth and beer, stirring well. Bring to a boil, then reduce heat and simmer for 3 to 4 minutes, stirring occasionally. When the mixture has thickened slightly, add the potatoes and continue to simmer, approximately 12 minutes, until potatoes are cooked through. Add milk, cheeses, salt, and flavorings. Stir constantly over low heat until cheese is smooth. Top with sliced green onions and serve with toasted crusty bread.
