How to Make Potato Soup, Plus the Best Potatoes to Use

Potato soup is one of those magical meals that makes your kitchen smell like someone loves you. It’s cozy, budget-friendly, and flexible enough to work on a busy weeknight or as a “look, I totally planned this” weekend dinner. But the secret to truly great potato soup isn’t just cream, cheese, or bacon (although, yes please). It starts with choosing the right potato.

If you’ve ever made potato soup that turned gluey, watery, or weirdly bland, the potato type was probably the culprit. In this guide, you’ll learn exactly how to make potato soup from scratch, which potatoes give you the texture you want, and how to avoid common mistakes that can turn a comfort-food classic into a starchy science experiment.

Why Potato Choice Matters in Potato Soup

Not all potatoes cook the same way. Some break down quickly and create a thick, velvety soup. Others stay firm and hold their shape, which is great if you want visible chunks and a more brothy texture.

For potato soup, texture is everything. The “best” potato depends on the style you want:

• Silky and thick: go with starchy potatoes (like russets).
• Creamy with soft chunks: go with yellow potatoes (often sold as Yukon Gold or “gold” potatoes).
• Chunky and brothy: go with waxy potatoes (like red potatoes).
• Best of both worlds: use a mix of russet + yellow potatoes.

That last option is the move many cooks swear by. One potato thickens the soup naturally, while the other keeps pleasant bites in the bowl. Basically, it’s teamwork… but edible.

The Best Potatoes to Use for Potato Soup

1) Russet Potatoes (Best for Thick, Creamy Potato Soup)

Russets are high in starch and lower in moisture, which means they cook up fluffy and break down easily. In soup, that’s a gift. As they simmer, they naturally thicken the broth and create that classic creamy potato soup texture without needing a ton of flour or cornstarch.

Best for: smooth, hearty, loaded baked potato-style soup

Watch out for: over-mixing or aggressive blending, which can make any potato soup gummy (especially when combined with dairy)

2) Yukon Gold (or Yellow Potatoes) (Best for Creamy Texture + Flavor)

Yukon Gold potatoes are often treated as the all-purpose hero. They have a naturally buttery flavor and a balanced starch/moisture level, so they get creamy without collapsing as quickly as russets. If your goal is a soup with body plus tender chunks, yellow potatoes are a fantastic choice.

Best for: rustic creamy soups, potato-leek soup, soups you want to partially mash

Watch out for: supermarket labelsmany stores sell “gold” or “yellow” potatoes that may not be true Yukon Gold, but they usually work similarly enough for soup

3) Red Potatoes (Best for Chunky, Brothy Soups)

Red potatoes are waxier and hold their shape well. If you want distinct potato pieces in every spoonful and a lighter soup that eats more like a stew, reds are a good fit.

Best for: chunky soups, vegetable-forward potato soups, soups with sausage or kale

Watch out for: expecting them to thicken the pot on their ownthey usually won’t

4) The Smartest Choice: Mix Your Potatoes

If you want a restaurant-style result, use half russet and half yellow potatoes. The russets melt into the broth and create thickness, while the yellow potatoes keep the soup creamy and textured. This combo gives you a rich spoonful without turning the whole pot into mashed potatoes with ambition.

How to Make Potato Soup (Step-by-Step)

This method makes a classic stovetop potato soup that’s easy to customize. It’s creamy, flavorful, and built on real technique instead of just “dump and pray.”

Ingredients (Base Recipe)

• 2 1/2 to 3 pounds potatoes (russet, yellow, or a mix), peeled and diced
• 2 tablespoons butter (or olive oil)
• 1 medium onion, diced
• 2 cloves garlic, minced
• 4 cups chicken or vegetable broth
• 1 to 1 1/2 cups milk, half-and-half, or cream (depending on richness you want)
• Salt and black pepper, to taste
• Optional: 1 celery stalk and 1 carrot, finely diced (for more depth)
• Optional toppings: shredded cheddar, chives, bacon, sour cream, scallions, croutons

Step 1: Build Flavor First (Don’t Skip the Onion)

Heat butter in a heavy pot or Dutch oven over medium heat. Add onion (and celery/carrot if using) and cook until softened, about 5–7 minutes. Add garlic and cook for 30–60 seconds, just until fragrant.

This base matters. Potato soup can taste flat if all the flavor comes from dairy and salt. Aromatics give it depth before the potatoes even show up to the party.

Step 2: Add Potatoes and Broth

Add diced potatoes and broth. Bring to a gentle boil, then reduce to a simmer. Cook until the potatoes are fork-tender, usually 15–25 minutes depending on cube size and potato variety.

Pro tip: Cut the potatoes into similar-size pieces so they cook evenly. Nobody wants half the pot mushy and the other half crunchy.

Step 3: Thicken the Soup (Three Easy Options)

Once the potatoes are tender, choose your texture:

• Chunky: Leave it as-is and lightly mash just a few potatoes against the side of the pot.
• Creamy: Mash about one-third to one-half of the potatoes with a potato masher.
• Smooth: Use an immersion blender briefly, pulsing gently. Don’t over-blend.

If the soup still seems thin, add one of these:

• A little more mashing
• A small slurry (1 tablespoon cornstarch + 1 tablespoon cold water)
• A spoonful or two of instant mashed potato flakes (a surprisingly useful thickening trick)

Step 4: Add Dairy Gently

Lower the heat before adding milk, half-and-half, or cream. Stir it in and warm through without boiling hard. High heat can cause dairy to separate, especially in thinner soups.

Taste and season with salt and pepper. Potatoes need more salt than many people expect, so season gradually and taste after each addition.

Step 5: Top It and Serve

Ladle into bowls and finish with your favorite toppings. Classic loaded potato soup toppings include cheddar, bacon, sour cream, and chives. For a lighter version, try olive oil, black pepper, parsley, and a squeeze of lemon.

Serve with crusty bread, a simple salad, or a grilled cheese if you’re leaning hard into comfort food (highly recommended).

Common Potato Soup Mistakes (and How to Fix Them)

Mistake #1: Using the Wrong Potato for the Texture You Want

Waxy potatoes won’t magically become thick and velvety. Russets won’t stay in perfect cubes forever. Match the potato to the style of soup and you’ll avoid half your problems immediately.

Mistake #2: Over-Blending

Potatoes release starch as they break down. Blend too aggressively and the soup can turn gluey. If you want it smoother, pulse briefly and stop early. Rustic beats gummy every time.

Mistake #3: Under-Seasoning

Potatoes are delicious, but they are also little flavor sponges. If your soup tastes bland, it probably needs salt, pepper, and maybe a touch of acid (like a tiny splash of lemon juice) to brighten it up.

Mistake #4: Adding Dairy Too Early

Adding cream before the potatoes are fully tender can slow cooking and increase the risk of scorching. Get the potatoes soft first, then make it rich.

Mistake #5: Not Adjusting Thickness at the End

Potato soup thickens as it cools. If it looks perfect on the stove, it may be very thick tomorrow. Keep extra broth on hand so you can loosen leftovers when reheating.

How to Customize Potato Soup

Loaded Baked Potato Soup Style

Use mostly russets, make it thick, and top with cheddar, bacon, sour cream, and chives. This is the soup equivalent of wearing fuzzy socks and canceling plans.

Potato Leek Soup Style

Swap onion for leeks, use yellow potatoes, and keep the texture slightly rustic or blend smooth. Finish with black pepper and a drizzle of cream.

Vegetable Potato Soup

Add carrots, celery, corn, peas, or kale. Use red or yellow potatoes if you want the vegetables and potatoes to stay distinct in the broth.

Cheesy Potato Soup

Stir in shredded cheddar at the end over low heat. Add cheese gradually and avoid boiling after it’s added to keep the texture smooth.

Protein Add-Ins

Try browned sausage, shredded chicken, ham, or crispy bacon. Hearty add-ins pair especially well with chunkier potato styles and mixed-potato soups.

Can You Prep Potatoes Ahead for Soup?

Yes. If you want to save time, peel and cut the potatoes ahead of time and store them in cold water in the refrigerator. This helps prevent browning. When you’re ready to cook, drain and proceed.

If you’re worried about “losing all the starch,” don’t be. The potatoes still contain plenty to help thicken soup, especially if you’re using russets. And if you need more body later, mashing more potatoes (or using a small thickener boost) works beautifully.

Storage, Leftovers, and Reheating

Potato soup is excellent the next day, but it usually thickens in the fridge. Store leftovers in a sealed container and add a splash of broth or milk when reheating to bring it back to life.

• Refrigerator: Best within 3–4 days
• Freezer: Possible, but dairy-based soups can change texture (freeze before adding cream for best results)
• Reheating: Reheat gently on the stove, stirring often, until hot throughout

If you’re serving leftovers to a crowd, use standard food-safety practices: cool promptly, refrigerate in a timely way, and reheat thoroughly. (This is the least glamorous part of soup-making, but definitely the most useful.)

Conclusion: The Best Potato Soup Starts with the Potato

Making great potato soup is less about fancy ingredients and more about smart choices. If you want thick and velvety, choose russets. If you want creamy bites and buttery flavor, choose yellow potatoes. If you want a chunkier, brothier bowl, choose red potatoes. And if you want the easiest route to “wow, this is amazing,” use a mix of russet and yellow potatoes.

Once you understand how each potato behaves, potato soup becomes one of the easiest soups to master. You can keep it simple and classic, load it up like a baked potato, or turn it into a clean-out-the-fridge masterpiece. Either way, you’ll end up with a bowl of comfort that tastes like you know exactly what you’re doing (even if you’re wearing pajamas and winging it).

Extended Practical Experiences (500+ Words): What Home Cooks Commonly Learn When Making Potato Soup

One of the most common experiences people have with potato soup is discovering that the same recipe can produce very different results depending on the potatoes used. A cook might follow a “creamy potato soup” recipe exactly, but if they use red potatoes instead of russets, the soup may taste good while staying thinner than expected. This often leads to the false conclusion that the recipe is bad, when the real issue is texture mismatch. In practice, most home cooks get better results once they stop thinking of potatoes as one ingredient and start thinking in categories: starchy, all-purpose, and waxy.

Another frequent experience is accidentally over-puréeing the soup. It usually starts innocently: the soup looks a little chunky, so the blender runs a little longer, and suddenly the texture turns heavy or gluey. This is a classic potato-soup lesson. Cooks who make potato soup regularly tend to switch from “blend until smooth” to “blend just enough.” Many even prefer a partially mashed soup because it feels more homemade, reheats better, and has more character in each spoonful.

People also learn quickly that potato soup is a salt-and-seasoning balancing act. Early in the cooking process, it can taste underwhelming even if it smells fantastic. Potatoes absorb seasoning, so soups often need more salt than expected, plus black pepper and something aromatic (onion, garlic, leek, herbs) to taste complete. A common success story is adding a small finishing touchchives, cheddar, sour cream, crispy bacon, parsley, or even a tiny squeeze of lemonand watching the entire bowl “wake up.” The soup didn’t need a complete overhaul; it just needed contrast.

Texture management over time is another real-world lesson. Fresh off the stove, potato soup can look loose and silky. The next day, it may thicken dramatically in the refrigerator. Newer cooks sometimes think leftovers have gone wrong, but experienced soup makers know this is normal. They reheat gently and loosen the soup with broth or milk, stirring as it warms. In fact, many people prefer day-two potato soup because the flavors settle and deepen overnight.

There’s also a practical budgeting lesson that shows up again and again: potato soup is one of the easiest ways to make a satisfying meal from inexpensive ingredients. A few potatoes, onion, broth, and milk can feed multiple people, and toppings can be as simple or as fancy as the situation allows. Families often develop “house versions” based on what’s availableham after a holiday meal, extra cheddar from taco night, leftover corn, or a handful of spinach that needs to be used. This is part of potato soup’s long-term appeal: it is forgiving, adaptable, and rewarding.

Finally, many cooks report that the biggest confidence boost comes from learning a repeatable method instead of memorizing a single recipe. Once they understand the patternsauté aromatics, simmer potatoes, mash or blend for texture, add dairy gently, season wellthey can improvise without stress. That’s when potato soup stops being a recipe and becomes a skill. And honestly, that’s the best kind of comfort food: the kind you can make well, on purpose, whenever the weather says “soup” (or when your refrigerator says “use these potatoes now”).
