Creamy Potato Soup delivers a luscious, velvety texture through a classic bechamel-style white sauce.
Passed down from the granddaughter of an Idaho potato farmer, this recipe builds flavor by simmering diced potatoes and carrots in bouillon-spiked water, then folding in a rich butter-and-milk sauce. The result is a soup that feels indulgent and comforting, even before you add the optional cheddar and green onions. It comes together in about thirty minutes, making it a practical choice for a weeknight dinner that still feels special.
The technique is straightforward: boil your vegetables until they’re tender enough to mash with a fork, prepare a smooth white sauce by whisking milk into a butter-flour roux, then combine the two. You control the final texture, whether you prefer a chunky, rustic bowl or a silky-smooth puree.
What You’ll Need for Creamy Potato Soup
This lineup is simple, relying on pantry staples and fresh vegetables to build a soup base that tastes rich without requiring cream or cheese.
- Potatoes – the foundation of the soup, providing starch and body when mashed.
- Carrots – add subtle sweetness and color to the broth.
- Garlic – brings a gentle aromatic backbone.
- Better Than Bouillon – concentrated paste that delivers deep, savory flavor to the cooking liquid.
- Parsley – fresh or dried, it adds a bright herbal note.
- Butter – forms the base of the white sauce and contributes richness.
- All-purpose flour – thickens the sauce when cooked into a roux.
- Whole milk – creates the creamy, luxurious texture that defines this soup.
- Kosher salt and black pepper – season both the vegetable base and the white sauce.
- Optional garnishes – cheddar cheese, green onions, and extra parsley add texture and flavor contrast.
How to Make Creamy Potato Soup Step by Step
STEP 1: Peel and dice the potatoes into roughly half-inch pieces, then place them in a three-quart pot. Peel and dice the carrots to match the potato size, then add them to the pot along with the minced garlic.
STEP 2: Pour in three cups of water, adjusting the amount so the vegetables are just barely covered. Stir in a heaping tablespoon of Better Than Bouillon, the parsley, and one teaspoon of kosher salt. Bring the mixture to a boil over high heat, then reduce to a steady simmer with the lid vented.
STEP 3: Simmer for about twenty minutes, until the potatoes and carrots are tender enough to mash easily with a fork. Remove from heat and use a potato masher to break down the vegetables to your preferred texture, leaving some chunks for a rustic feel or mashing more thoroughly for a smoother base.
STEP 4: While the vegetables simmer, melt half a cup of butter in a separate two-quart pot over medium heat. Whisk in half a cup of flour to form a paste, then add half a teaspoon each of salt and pepper. Cook the roux for one to three minutes, stirring constantly to eliminate the raw flour taste.
STEP 5: Add the four cups of milk slowly, one cup at a time, whisking thoroughly after each addition to incorporate the liquid into the roux without forming lumps. Continue stirring often as the mixture heats, bringing it to a full boil with consistent bubbles rising from the center. Let it boil for one minute, then remove from heat.
STEP 6: Pour the white sauce into the pot with the mashed vegetables, scraping every bit of the sauce in with a spatula. Stir everything together until fully combined, then taste and adjust seasoning if needed.
STEP 7: Serve the soup warm, garnishing each bowl with shredded cheddar, chopped green onions, and a sprinkle of fresh parsley.
Secrets for a Seriously Creamy Potato Soup
- Add the milk to the roux gradually, one cup at a time, whisking thoroughly between additions to prevent lumps from forming in the white sauce.
- Keep the heat at medium while making the bechamel and stir frequently to avoid scorching the bottom of the pot, especially once the milk is fully incorporated.
- Simmer the potatoes and carrots until they’re very tender, soft enough to mash easily with a fork, so the soup develops a velvety base rather than a watery broth with hard vegetable chunks.
- Warm the milk in the microwave for a couple of minutes before adding it to the roux if you want the white sauce to thicken faster and come together more smoothly.
Favorite Sides and Toppings for Creamy Potato Soup
This soup pairs beautifully with crusty bread or buttered rolls for dipping, soaking up every bit of the creamy broth. A simple green salad with a tangy vinaigrette balances the richness, while a grilled cheese sandwich turns the meal into a comforting, nostalgic dinner. For toppings, shredded cheddar adds sharpness and melt, chopped green onions bring a fresh bite, and extra parsley brightens the bowl with color and herbal lift.
Creamy Potato Soup Questions, Answered
Can I substitute a different bouillon or broth base?
You can use bouillon granules or cubes instead of Better Than Bouillon, but reduce the amount since they tend to be much saltier. Start with one to two teaspoons and taste before adding more. Liquid chicken or vegetable broth also works, though you may need to reduce the water slightly to maintain the concentrated flavor.
Is it possible to make this soup vegetarian?
Switch to vegetable bouillon or a vegetable broth base and use the same proportions. The soup will still develop a rich, savory flavor from the white sauce and the natural starch released by the potatoes. Consider adding a pinch of smoked paprika or nutritional yeast for extra depth.
What’s the best way to get the soup ultra-smooth or leave it chunky?
For a chunky texture, skip the mashing step entirely and leave the vegetables in large, tender pieces. For a velvety soup with some texture, use a potato masher to break down most of the vegetables while leaving a few chunks. For an ultra-smooth puree, use an immersion blender directly in the pot after simmering.
Why shouldn’t I freeze this potato soup?
Potatoes absorb a significant amount of moisture during freezing and thawing, which causes the white sauce to separate and the soup to turn grainy and unappetizing. The texture breaks down completely, so it’s better to store leftovers in the fridge and enjoy them within five days or share the batch with a friend.
How do I prevent a lumpy white sauce?
Add the milk slowly, one cup at a time, and whisk thoroughly after each addition to fully incorporate the liquid into the roux before adding more. Rushing this step or dumping all the milk in at once will create flour clumps that are difficult to smooth out. Keeping the heat at medium and stirring constantly also helps the sauce come together evenly.
How to Store (and Why Not to Freeze) Creamy Potato Soup
Store leftovers in an airtight container in the refrigerator for up to five days. Reheat gently on the stovetop over medium-low heat, stirring often to prevent scorching, or warm individual portions in the microwave. The soup may thicken as it sits, so you can thin it with a splash of milk or broth when reheating.
Do not freeze this soup. The potatoes will absorb excess moisture during the freezing and thawing process, causing the white sauce to separate and the texture to become grainy and unpleasant. If you have more soup than you can eat within five days, invite someone over to share a warm bowl instead.

Method
- Peel and dice the potatoes into 1/2-inch pieces and transfer them to a stock pot or 3-quart pot.
- Dice the carrots to a similar size and add them to the pot.
- Add the minced garlic to the pot.
- Pour in the water so the vegetables are just covered, adjusting as needed. Stir in the heaping tablespoon of Better Than Bouillon Base.
- Add the fresh or dried parsley and the teaspoon of kosher salt. Bring everything to a boil over high heat, then reduce to medium and keep at a gentle simmer. Partially cover the pot, leaving the lid vented. Simmer for about 20 minutes, or until the potatoes and carrots are very tender and easily mashed with a fork.
- Take the pot off the heat. Use a potato masher to mash the vegetables until you reach your preferred texture, whether chunky or mostly smooth.
- While the vegetables cook, melt the butter in a 2-quart or larger saucepan over medium heat. Stir in the flour with a whisk to form a paste.
- Add the kosher salt and black pepper to the paste and cook, stirring constantly, for 1 to 3 minutes.
- Gradually add the milk, one cup at a time, whisking well after each addition to fully combine before adding more. This should take a few minutes and helps prevent lumps.
- Once all the milk is incorporated, continue stirring often. Bring the sauce to a boil over medium heat, then let it boil for one minute, stirring the entire time. Remove from heat.
- Pour the white sauce into the pot with the mashed vegetable mixture. Use a spatula to scrape all of the sauce in, and stir until combined.
- Serve the soup hot, topped with chopped parsley, shredded cheddar cheese, and green onions if you like.
- Refrigerate any leftovers for up to 5 days. Do not freeze, as the texture will change and become grainy.
- For quicker results, you can warm the 4 cups of milk in the microwave before adding it to the roux.
