This might be the easiest and healthiest method for how to make potato soup. This soup is thick and creamy, yet doesn't start with a roux – so it's perfect for those that eat gluten-free! The key to thickening this soup is to puree some of it while it's cooking. It's a genius method that I have to credit my brother with (actually… the entire recipe is basically his).
Another trick is to boil the onions in salt water prior to adding the other ingredients; this softens them up nicely (I'm not a fan of crunchy onions in my soups :))
But the best thing about this soup is how cheap it is! This will easily cost less than $5 to make. Top with some shredded cheese, and serve with a good bread and you have a delicious meal.
