Ingredients for 4-Ingredient Cheddar Potato Soup
This recipe makes approximately 4 servings.
Ingredients
- 2 pounds (900 g) russet potatoes, peeled and diced
- 4 cups (960 ml) whole milk
- 2 cups (about 200 g) freshly shredded sharp cheddar cheese
- 3 tablespoons (42 g) unsalted butter
Ingredient tip: Russet potatoes are ideal because they break down easily and help thicken the soup. Sharp cheddar provides a stronger cheese flavor than mild cheddar. For the smoothest results, shred the cheese yourself rather than using pre-shredded cheese, which may contain anti-caking agents.
These four ingredients create the base of the soup. If you have extra seasonings available, salt and black pepper can be added to taste, but they are optional extras rather than essential ingredients.
How to Make 4-Ingredient Cheddar Potato Soup
Step 1: Prepare the Potatoes
Peel the potatoes and cut them into small, evenly sized cubes, approximately 1/2 inch (1.3 cm) wide. Cutting the potatoes evenly helps them cook at the same rate.
Place the diced potatoes in a large saucepan and cover them with water. Bring to a boil, then reduce the heat and simmer for approximately 12–15 minutes, or until the potatoes are fork-tender.
Drain the potatoes thoroughly. Reserve a small amount of the cooking water if you want to adjust the soup’s consistency later.
Step 2: Warm the Milk and Butter
Return the empty saucepan to the stove over low to medium-low heat. Add the butter and allow it to melt gently.
Pour in the milk and stir slowly until it becomes warm. Do not let the milk boil vigorously, because excessive heat can cause scorching and affect the texture of the finished soup.
For extra flavor, you can use a heavy-bottomed saucepan, which distributes heat more evenly and helps prevent the milk from sticking to the bottom.
Step 3: Add the Cooked Potatoes
Add the drained potatoes to the warm milk and butter mixture. Stir gently to combine.
For a chunky potato soup, use a potato masher to crush some of the potatoes while leaving the remaining pieces intact. If you prefer a smoother texture, mash more thoroughly or blend a portion of the soup with an immersion blender.
Avoid blending the soup excessively, especially if you’re using starchy russet potatoes, as this can create a gluey texture.
Step 4: Melt in the Cheddar Cheese
Reduce the heat to low. Gradually add the shredded cheddar cheese, stirring after each addition until it melts into the soup.
Keep the temperature gentle and avoid boiling the soup after adding the cheese. High heat can cause cheddar to separate and become grainy instead of creating a smooth, creamy texture.
Continue stirring until the cheese is fully incorporated. If the soup is too thick, add a little reserved potato cooking water or additional warm milk until you reach your preferred consistency.
Step 5: Serve Warm
Taste the soup and add salt or black pepper if desired. Ladle it into bowls and serve immediately while warm and creamy.
For an optional garnish, sprinkle a little extra cheddar cheese over each bowl. Chopped chives, green onions, or crispy bacon also make delicious toppings, although these additions are not included in the four-ingredient base recipe.
Tips for the Best Cheddar Potato Soup
Choose the right potatoes. Russet potatoes are excellent for a thick, hearty soup, while Yukon Gold potatoes provide a naturally buttery flavor and a slightly creamier texture.
Shred the cheese fresh. Freshly shredded cheddar usually melts more smoothly than packaged shredded cheese.
Keep the heat low. Gentle heating is essential when working with milk and cheese. Avoid rapid boiling to help maintain a creamy consistency.
Control the thickness. Mash some of the potatoes for a thicker soup, or add warm milk gradually if you prefer a thinner broth.
Make it your own. Although the original base contains only four ingredients, optional toppings and seasonings can add variety. Try smoked paprika, garlic powder, green onions, or cooked bacon.
What to Serve with Cheddar Potato Soup
This creamy potato soup is filling enough to enjoy on its own, but it also pairs well with simple side dishes.
Serve it with crusty bread, garlic toast, or homemade dinner rolls for dipping. A fresh green salad with a light vinaigrette adds a refreshing contrast to the rich cheddar flavor.
For a more substantial meal, pair the soup with a grilled cheese sandwich, roasted vegetables, or a simple chicken sandwich. These combinations are ideal for a cozy family lunch or an easy weeknight dinner.
How to Store and Reheat Potato Soup
Refrigerator: Allow the soup to cool slightly and transfer it to an airtight container. Refrigerate within two hours of cooking and consume within 3–4 days.
Freezer: Dairy-based potato soup may separate or become grainy after freezing, so freezing is not the best option for maintaining its original creamy texture. If you choose to freeze it, expect some texture changes after thawing and reheating.
Reheating: Warm the soup in a saucepan over low heat, stirring frequently. Add a splash of milk if it has thickened during storage. Avoid boiling, as the cheese and milk may separate.
For food safety, reheat leftovers to 165°F (74°C).
Frequently Asked Questions
Can I make potato soup with only four ingredients?
Yes. Potatoes, milk, cheddar cheese, and butter are enough to prepare a simple, creamy potato soup. Optional seasonings and toppings can be added, but they are not necessary for the basic recipe.
How do I make cheddar potato soup thicker?
Mash some of the cooked potatoes directly into the soup. The released starch helps thicken the liquid naturally without requiring flour or cornstarch.
Why is my potato cheese soup grainy?
Graininess often occurs when cheese is heated too quickly or the soup boils after the cheese has been added. Keep the heat low and stir in the cheddar gradually.
Can I use a different type of cheese?
Yes. Monterey Jack, mild cheddar, or a cheddar blend can work well. However, sharp cheddar generally provides the most pronounced flavor. Different cheeses may produce slightly different textures.
Can I make this soup without whole milk?
Whole milk provides a rich texture, but you can use 2% milk if necessary. The soup may be less creamy. Unsweetened plant-based milk can also work, although the flavor and consistency will differ.
Is this potato soup vegetarian?
The four-ingredient recipe can be vegetarian if you use a cheddar cheese made without animal-derived rennet. Check the cheese label if vegetarian suitability is important to you.
