Peel and chop baked potatoes and set aside. Chop ham and set aside.
In a large pot or Dutch oven add Avocado oil or butter. (Sauté onion and celery if you have it until soft) Add flour and stir to cook for a minute or two. Pour in the milk and seasonings, whisk together and bring to a boil.
Add chopped potatoes and corn and simmer until heated through. Stirring frequently to prevent sticking.
Taste and adjust seasonings as needed. Add a splash of milk if the soup is too thick.
Ladle into a bowl and serve with shredded cheese, ham and chives. Bacon and sour cream would also be delicious! Enjoy!
