Creamy Red Potato Soup (Ready in 30 Minutes)
This creamy red potato soup is the kind of meal you can pull together after work without a trip to the store. The thin red skins blend right in, so there’s no peeling and no waste.
It’s silky, deeply savory, and feels like a treat, but every ingredient is a kitchen staple. Even better, it’s ready in about half an hour.
Why This Red Potato Soup Works
Red potatoes have a thin, tender skin that disappears into the soup when you blend it. That means no peeling, less prep, and a hint of earthy color in every spoonful.
A quick butter-and-flour roux gives the broth body without any heavy cream. The soup tastes rich and creamy, but the ingredient list stays short and simple.
Ingredients
- 2 tbsp unsalted butter: use salted butter if that’s what you have, just back off on added salt later
- 1 medium yellow onion, diced: about 1 cup; white onion works too
- 2 garlic cloves, minced: use fresh, not jarred
- 2 tbsp all-purpose flour: helps thicken the soup without cream
- 4 cups low-sodium vegetable or chicken broth: low-sodium lets you control the salt
- 2 lbs red potatoes, unpeeled, diced into 1-inch pieces: about 5 medium potatoes
- 1 tsp fine sea salt: adjust to your broth’s saltiness
- ½ tsp black pepper: freshly ground if you have it
- ½ cup whole milk: half-and-half makes it even richer
- Optional for serving: shredded sharp cheddar, sliced chives, crumbled bacon
Variations / Substitutions
- Swap the onion: a large leek (white and light green parts only) gives a milder, sweeter base
- Add some greens: stir in a handful of baby spinach after blending and let it wilt for a minute
- Make it dairy-free: use olive oil instead of butter, skip the flour or use a gluten-free all-purpose blend, and stir in oat milk or full-fat coconut milk at the end; leave off the cheese
- Give it a smoky edge: sauté ½ teaspoon smoked paprika with the garlic
- Make it meaty: cook 4 slices of diced bacon first, set aside, and use the rendered fat for the onion; stir the crispy bacon back in at the end

How to Make Creamy Red Potato Soup
Step 1: Sauté the Onion and Garlic
Set a large pot or Dutch oven over medium heat and melt the 2 tbsp butter. Add the diced onion and cook, stirring now and then, for about 5 minutes, until the pieces look translucent and soft.
Toss in the 2 minced garlic cloves and cook 1 minute more, just until it smells fragrant. Sprinkle the 2 tbsp flour over everything and stir constantly for 2 minutes; the flour should lose its raw smell and turn a shade darker.
Step 2: Simmer the Potatoes
Pour in the 4 cups broth slowly while whisking to break up any flour lumps. Add the 2 lbs diced red potatoes, 1 tsp salt, and ½ tsp black pepper. Bring the pot to a rolling boil, then lower the heat to a steady simmer.
Cover the pot and let it bubble gently for 15 to 18 minutes. You’ll know the potatoes are ready when a paring knife slides through a cube without any resistance.
Step 3: Blend Until Smooth
Take the pot off the heat. Use an immersion blender to purée the soup right in the pot until it’s velvety and no chunks remain. If you use a stand blender, work in batches and vent the lid to let steam escape.
Stir in the ½ cup whole milk, set the pot back over low heat, and warm for 2 minutes to bring everything together. Taste and add a pinch more salt or pepper if it needs it.
Step 4: Ladle and Garnish
Spoon the hot soup into bowls while it’s still steaming. Scatter a small handful of shredded sharp cheddar, a few slices of chives, and a crumble of bacon over the top.
Serve right away. The cheese will soften into the creamy soup, and the chives add a fresh bite that cuts through the richness.
A Few Tips for Smooth Red Potato Soup
- An immersion blender is the quickest and safest way to purée the soup; you never have to handle hot liquid in a blender jar.
- For a soup with a little more texture, blend only half the pot, then stir the blended portion back into the chunky base.
- If the soup thickens more than you like, thin it with a splash of broth or milk while you reheat it.
- A diced celery rib cooked with the onion adds a subtle herbaceous note without changing the creamy feel.
Simmer time depends on how small you dice the potatoes:
| Dice size (approx) | Simmer time |
|---|---|
| ½-inch cubes | 12–15 mins |
| 1-inch cubes | 15–18 mins |
| 1½-inch chunks | 18–22 mins |
Storing and Reheating Leftovers
- Refrigerate: pack the cooled soup into an airtight container and keep it in the fridge for up to 4 days.
- Reheating: warm it gently on the stovetop, stirring often. Add a splash of broth or milk if it looks too thick.
- Freeze: you can freeze the soup for up to 3 months, but red potato soup can soften slightly when thawed. The texture is still pleasant, just not quite as velvety.
What to Serve With Red Potato Soup
A loaf of crusty sourdough or a hot grilled cheese sandwich is the obvious dunking partner; the crisp edges and gooey center are a great match for a bowl of creamy soup. If you want something lighter, a simple green salad dressed with a sharp vinaigrette cuts the richness and rounds out the meal.
Frequently Asked Questions
Can I use Yukon Gold or russet potatoes instead?
Yes. Yukon Golds will give a buttery color and a slightly thicker texture. Russets will make the soup fluffier and starchier, so you may need a little more broth to thin it.
How do I make this dairy-free?
Use olive oil in place of butter, skip the flour or swap in a 1:1 gluten-free flour blend, and stir in unsweetened oat milk or full-fat coconut milk at the end. Skip the cheese topping or use a plant-based shred.
Can I freeze the soup?
You can freeze it in a sealed container for up to 3 months. The potato may soften after thawing, so the soup won’t be quite as smooth, but it still tastes great.
My soup is thin. How can I thicken it?
The potatoes usually do the job, but if it’s too thin, simmer the soup uncovered for 5 to 10 minutes to evaporate some liquid. You can also mash a few extra boiled potato cubes into the pot.
