Get a large pot out and take all the extra meat off the turkey carcas and set aside. Place the carcas and any large bones in a large pot and cover with water. Bring to a boil and simmer for at least 30 minutes, skimming away any yucky stuff  that comes to the surface 

Peel the onion, carrots, and potato and cut into ½ inch pieces. Finely slice the bacon. 

Fry the bacon in a large pan until cooked and remove and set aside 

Add the onion, carrots, potatoes into the pan that the bacon was cooking in, and cook until the vegetables are soft, stirring regularly to prevent sticking 

Pour the broth through a sieve into a heavy bottom pot and add the cooked vegetables, corn, and leftover turkey meat. 

Using an immersion blender, blend some of the soup together. Leaving some chunks. 

Remove from heat and add the cream. Season with salt and pepper. Garnish with bacon and parsley and enjoy! 

Tip: if you want it thinner add some water
