Creating your own 4-Ingredient Potato Soup is quite simple! Just follow these easy steps:

1. Prep the Potatoes: Peel and dice the potatoes into even-sized cubes to ensure they cook uniformly.
2. Heat the Broth: In a large pot, bring the vegetable or chicken broth to a boil over medium-high heat.
3. Cook the Potatoes: Add the diced potatoes to the boiling broth. Reduce the heat to a simmer and cook for about 15 minutes, or until the potatoes are tender.
4. Mash the Potatoes: Once the potatoes are cooked, use a potato masher or a fork to mash them directly in the pot, achieving your desired consistency.
5. Add Milk: Slowly stir in the milk, mixing well to combine. Let the soup heat for an additional 2-3 minutes.
6. Season: Add salt and pepper to taste, adjusting according to your preference.
7. Serve: Carefully ladle the hot soup into bowls.

As you can see, making this incredible soup is straightforward and quick!
