Tuscan White Bean and Garlic Soup

Got this recipe off Food Network. This recipe is originally from Giada De Laurentis. I halved the proportions because I only had 1 can of beans, but the proportions were somehow not quite right. The soup turned out a little too watery even after blending. Will try this recipe again though.

Ingredients (Based on the original 6-8 servings)

2 tbsp butter
1 tbsp olive oil
2 onions, chopped
1 tsp dried thyme (original recipe used 1 sage leaf)
3 cups canned cannelli beans, drained and rinsed
4 cups chicken stock
4 cloves garlic, cut in half
1/2 cup milk (original recipe used cream)
1/2 teaspoon ground black pepper

Directions
Place a medium sized pot over medium heat.
Add butter, olive oil and onions. Cook until onions are softened.
Add thyme and beans. Stir to combine.
Add stock and bring mixture to a simmer.
Add garlic and simmer until the garlic is softened.
Blend about 1/2 of the soup into a puree. Return the puree into the pot.
Add cream and pepper.
Simmer over low heat.

Serve with toasted bread.
