'Grandma’s Cold-Weather Staple': Just 4 ingredients. I make it on repeat because it always hits the spot.

Place the diced potatoes in a medium pot and add just enough water to cover them. Bring to a boil over medium-high heat, then reduce to a gentle simmer and cook until the potatoes are very tender, about 12–15 minutes.

Drain the potatoes, leaving just a tablespoon or two of the cooking liquid in the pot. Lightly mash the potatoes with a spoon or potato masher, leaving some small chunks for texture.

Add the butter to the hot potatoes and stir until melted and well combined.

Pour in the milk and stir. Return the pot to medium heat and warm the mixture, stirring frequently, until it is hot but not boiling. Watch carefully so the milk doesn’t scorch on the bottom of the pot.

Reduce the heat to low. Add the shredded cheddar cheese a handful at a time, stirring constantly after each addition until the cheese is completely melted and the soup is smooth and creamy.

Taste and season with salt and black pepper if desired. Let the soup sit over very low heat for a few minutes to thicken slightly, stirring now and then.

Ladle into warm bowls and serve immediately while the soup is velvety and hot.

If you’d like a smoother soup, use a potato masher a bit more vigorously or run part of the soup through an immersion blender, then stir it back into the pot. For a heartier, farmhouse-style version, leave the potatoes in larger chunks and add a little less milk for a thicker texture. You can also swap part of the milk for chicken broth to lighten it slightly while keeping good flavor. A pinch of garlic powder or onion powder blends in nicely without adding extra chopping, and a dash of paprika or a sprinkle of extra cheddar on top makes it feel a bit special. If you have leftover ham or cooked bacon, stir in a small handful at the end for a more filling supper. And if you’re cooking for someone who prefers milder flavors, use a mild cheddar and add the cheese gradually, tasting as you go until it’s just right for your table.
