Baked Potato Cheddar Ham Soup with Sharp Cheese

A hearty, creamy soup that transforms classic loaded baked potato flavors into a warming bowl. Sharp cheddar cheese melts into a smooth milk base while chunks of tender baked potatoes provide satisfying texture. Diced ham adds protein and smoky flavor, while sour cream creates richness and tangy depth. Fresh green onions provide a bright finish that balances the rich, cheesy base. Perfect for cold weather comfort food or using up leftover baked potatoes and ham.

Tip 3

Reserve some cheese and green onions for garnish to add visual appeal and fresh flavor contrast.

FAQ

Can I use raw potatoes instead of baked?

Yes, but dice them small and cook 15-20 minutes longer until tender. Baked potatoes give better texture and flavor.

Can I freeze this soup?

Not recommended as dairy-based soups separate when frozen. The potatoes and sour cream will break down and affect texture.

What if my soup is too thin?

Mix 1 tablespoon flour with 2 tablespoons cold milk, whisk into soup and simmer until thickened.
