According to the Food Network, a simple recipe to make cream of potato and bacon soup uses russet potatoes as the base and involves blending the ingredients with cream and spices. Remove the hot liquids from the heat for at least five minutes before blending them.
To make this recipe according to FoodNetwork.com, start with thin slices of bacon, diced carrots, diced celery, diced onions and small russet potatoes that have been peeled and diced. Also gather Cajun spice mix, salt, black pepper and low-sodium chicken or vegetable broth. Milk, all-purpose flour, heavy cream, parsley and grated cheddar cheese round out the ingredients.
Put the bacon pieces in a soup pot, and heat the pot on medium. Cook the bacon until crisp, take it out of the pot, and set it aside. Pour some of the remaining grease out of the pot, but don't clean it. Turn the heat to medium-high, and add the carrots, onions and celery. Cook these ingredients for two minutes before adding the potatoes. Cook the soup for another five minutes, add the Cajun spice, salt and pepper, and then pour in the chicken broth. Bring the mixture to a boil. Cook the potatoes in the mixture until tender. In a separate bowl, mix the milk and flour, and add this to the soup. Cook the soup for five more minutes.
FoodNetwork.com advises taking half the soup out of the pot, letting it sit for five minutes and moving it to a blender. Blend the mixture until smooth, and put it back in the pot. Add the heavy cream and parsley to the soup. When the soup is done, serve it with grated cheese, and add the bacon pieces on top.
