Recipe: Cheeseburger Soup

Since I love to cook and bake, I thought I would share some recipes periodically on my blog. Here is a soup that I like to make when it's cold. My guys aren't big soup eaters but they all love this one. However, it is definitely not low-cal!!! But once in awhile it's good to have. I usually double the recipe and then freeze some individual servings for lunch.
1/2 lb. hamburger
3/4 c. onion, chopped
3/4 c. carrots, shredded
3/4 c. celery, diced
salt & pepper to taste
3 c. chicken stock
4 c. potatoes, peeled and diced
1/4 c. butter
1/4 c. flour
2 c. (8oz) Velveeta, cubed
1 & 1/2 c. milk
1/4 c. sour cream
In a large stockpot or dutch oven, brown hamburger and add onion, carrots and celery. Cook until meat is browned and vegetables are tender. Salt & pepper to taste. Add stock and potatoes, cover and cook until potatoes are tender, about 10-12 minutes. Meanwhile, in a small pan, melt butter and whisk in flour to make a roux. Add to soup and bring to a boil. Cook and stir for 2 minutes until thickened. Reduce heat to low. Add cheese and milk. Remove from heat when cheese is melted and stir in sour cream. Makes a little over 2 qts.
