Chunky Potato Soup

3 Tbsp. butter
1/4 c. flour
4 c. milk
2 c. diced potatoes
1/2 c. minced onions
2-3 stalks celery
1/2 tsp. salt
1/4 tsp-1/2 tsp. pepper

Melt butter in a heavy saucepan over low heat. Add flour, stirring until smooth. Cook 1 minute, stirring constantly. Gradually add milk. Stir in potatoes, onions, salt and pepper and celery. Cook over medium heat, stirring frequently, until mixture is thickened and potatoes and celery are tender.
* I also like to add crumbled bacon and seasoned salt on top. Yum!
