Dice 6 slices of bacon into 1/2 inch pieces. Cook the rest of the bacon separately, you'll be using it as a topping.
In a large pot, on medium high head, cook the 6 slices of bacon. Once the bacon is cooked, remove it from the pot with a slotted spoon and place on a plate covered with a paper towel. DO NOT REMOVE THE BACON FAT FROM THE POT!
Add the corn startch and cook for one minute.
Add the milk, cream, chicken broth, and potatoes to the pot. Bring to a simmer and cook until the potatoes are soft. Season with salt and pepper
Take off of the heat and blend until smooth. I like to use my immersion blender. Add in your cheese and bacon to the blended soup.
Serve topped with shredded cheddar, bacon bits, and green onion.
