Ingredients for 5 ingredient potato soup
Five simple ingredients transform into velvety comfort—no dairy needed.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 2 lb | Peeled and cubed evenly |
| Chicken Broth 💧 | 4 cups | Low-sodium preferred |
| Cream of Mushroom Soup 🍄 | 1 can (10.5 oz) | Condensed, unsweetened |
| Yellow Onion 🧅 | 1 whole | Diced small |
| Butter 🧈 | 2 tbsp | For sautéing onion |
The potatoes are the star here—Russet works best because it's naturally starchy and breaks down beautifully. Walmart or Kroger usually have them at a great price, especially in the fall. If you can't find Russets, Yukon Golds are a close second—they're creamier but slightly pricier. Peel and cube them about 1-inch in size for even cooking. The onion? Yellow is classic, but red adds a touch of color if you're feeling fancy. Just make sure to dice it small so it blends right into the soup without chunks.
No cream of mushroom soup? Homemade mushroom sauce is a great swap—simmer mushrooms, garlic, and a splash of broth, then blend. Short on broth? Water in a pinch, but the flavor will be milder. Butter hating you? Olive oil works just fine for sautéing. The key is blending the soup until it's completely smooth—immersion blender is easiest, but a regular blender works too. Just let it cool slightly before blending to avoid splattering. If you're worried about lumps, strain the soup through a fine-mesh sieve after blending.
This soup tastes even better the next day—3-4 days in the fridge, no problem. For leftovers, I like to reheat it on the stove with a splash of broth to keep it creamy. Freezes beautifully too—up to 3 months if you portion it into containers. The best part? It reheats like a dream, making it perfect for meal prep. Store it in a sealed container to keep the flavors locked in, and give it a stir before reheating to distribute all that creamy goodness.

Step-by-step instructions for creamy potato soup
Here's how to make this dreamy, dairy-free potato soup with just five ingredients—no heavy cream in sight.
🔥 Step 1: Sauté the Onion Until Soft and Sweet
Melt the 2 tbsp butter in a large pot over medium heat. Add the diced 1 whole yellow onion and cook for 5-6 minutes, stirring occasionally. You'll know it's ready when the onion becomes translucent and just starts to turn golden around the edges. This step builds flavor that carries through the whole soup.
Don't rush this part—I like to give the onions time to develop that sweet, caramelized taste. If they start to brown too quickly, reduce the heat slightly and keep stirring. The onions should be soft enough to pierce easily with a fork but not crispy.
🍳 Step 2: Add Potatoes and Broth to Simmer
Add the 2 lb peeled and cubed russet potatoes to the pot with the cooked onions. Pour in the 4 cups chicken broth, making sure all the potato cubes are submerged. Bring the mixture to a boil over medium-high heat, then immediately reduce to a gentle simmer.
Cover the pot and let it cook for 15-20 minutes, stirring occasionally. You'll see the potatoes start to soften and the broth begin to thicken slightly. The soup should bubble gently but not vigorously—this ensures even cooking without breaking up the potato pieces. Taste the broth now if you'd like; you can add salt if needed, but the cream of mushroom soup will add plenty of flavor later.
🥘 Step 3: Blend Until Silky Smooth
Once the potatoes are fork-tender (they should collapse easily when pierced with a fork), remove the pot from heat. Let it cool for 5 minutes—this prevents splattering when you blend. Using an immersion blender, blend the soup directly in the pot until completely smooth. If you prefer, you can also carefully transfer the soup to a blender in batches, but be cautious with hot liquids.
For the creamiest texture, I like to blend until there are no visible potato chunks at all. If the soup seems too thick after blending, add a splash of hot broth to reach your desired consistency. This step transforms your simple ingredients into that luxurious, velvety texture without any dairy.
🍲 Step 4: Stir in Cream of Mushroom for Rich Flavor
Return the pot to medium heat and stir in the 1 can (10.5 oz) cream of mushroom soup. Cook for 3-5 minutes, stirring constantly, until the soup is heated through and the flavors have melded together. The soup should be thick and creamy—if it's too thick, thin it with a little more hot broth.
Here's where the magic happens: the cream of mushroom soup adds that rich, savory depth without needing heavy cream. Taste and adjust seasoning with salt and pepper if needed. The soup should be flavorful but balanced—you want the potato and mushroom flavors to shine through.
🔥 Step 5: Finish with a Touch of Butter for Extra Richness
Remove the pot from heat and stir in 1 tablespoon of the remaining butter. This final touch adds a subtle richness that rounds out all the flavors. Let the soup sit for 2-3 minutes to thicken slightly, then taste one more time to ensure the seasoning is perfect.
Serve the soup hot, garnished with a sprinkle of the remaining butter on top for that restaurant-quality finish. Each spoonful should be creamy, comforting, and packed with potato flavor—proof that you don't need dairy to make a velvety soup. Enjoy immediately while it's hot!
Pro Tips For Making 5 Ingredient Potato Soup
- PEEL AND CUBE SMALL: Russet skins burn faster than you’d expect when simmering—cut them into 1-inch cubes, peel only the worst spots, and leave the rest on for texture. I learned this the hard way when my first batch turned into a sad, waterlogged mush.
- SWEAT THE ONION FIRST: Melt the butter in a pot, then cook the diced onion on medium-low for 8-10 minutes until translucent and golden. Skipping this step means your soup tastes raw and flat—like you forgot a critical flavor layer.
- STIR THE SOUP CONSISTENTLY: After adding the broth and potatoes, give it a solid 10-minute simmer before mixing in the cream soup. Stirring occasionally prevents the bottom from sticking and ensures even cooking—no lumps, no burnt bits.
- THIN WITH BROTH GRADUALLY: The cream soup thickens fast. If it’s too heavy, add the broth a splash at a time while tasting—you want smooth, not watery. I was skeptical until I tried it: the balance is everything.
Serving suggestions for 5 ingredient potato soup
Classic Garnishes
Start with a simple sprinkle of fresh parsley or chives—just 1 tablespoon chopped finely—right before serving. The bright green color adds visual appeal, while the freshness cuts through the richness. I like to use flat-leaf parsley from the grocery store because it holds its color better than dried herbs. For a smoky twist, try crispy bacon bits—cook 4 slices in a pan until crispy, then crumble over the top. 🥓
Crunchy Toppings
Add texture with toasted breadcrumbs or crushed Ritz crackers. For breadcrumbs, toast ¼ cup in a dry pan over medium heat for 2-3 minutes until golden. For crackers, pulse 8-10 Ritz in a food processor until finely crushed. Both add a satisfying crunch that contrasts beautifully with the silky soup. Store-bought croutons work too if you're short on time.
Creamy Finishes
If you want extra richness, stir in 2 tablespoons of sour cream or Greek yogurt before serving. For a decadent touch, drizzle with 1 tablespoon of melted butter or a swirl of homemade chive oil—simmer 2 tbsp olive oil with 1 tbsp chopped chives for 1 minute. The oil infuses with chive flavor and adds a luxurious sheen. 💛
Herb-Infused Oil
Make a quick herb-infused oil by combining ¼ cup olive oil with 1 tbsp each of fresh thyme, rosemary, and parsley. Heat gently for 1 minute, then strain and drizzle over the soup. This adds an aromatic depth that elevates the dish without overpowering the potato flavor. Store any leftover oil in the fridge for up to 1 week—it’s perfect for drizzling on salads too.
Bread Pairings
Serve with crusty sourdough or garlic bread to soak up every last drop. For garlic bread, brush 1 baguette with 2 tbsp melted butter, sprinkle with 1 tsp garlic powder, and toast in the oven at 375°F for 8-10 minutes. The crispy crust contrasts perfectly with the creamy soup. For a heartier option, try grilled cheese sandwiches made with sourdough and cheddar—the combo is a match made in comfort food heaven.
Beverage Pairings
Pair your soup with a crisp white wine like Sauvignon Blanc or Pinot Grigio—the acidity cleanses your palate between spoonfuls. For beer lovers, a light lager or wheat beer complements the creamy texture without overpowering it. If you prefer non-alcoholic options, sparkling apple cider or iced herbal tea with lemon adds a refreshing contrast. 🍷

Frequently asked questions
Can I make this soup without cream of mushroom soup?
For a dairy-free alternative, blend 1 cup cooked mushrooms with ½ cup broth until smooth, then use that instead. Or swap for 1 cup coconut milk (light or full-fat) for a richer, slightly sweet flavor. The key is maintaining that creamy texture—just adjust broth as needed after blending.
Why does my soup turn out lumpy even after blending?
Lumps usually happen if the potatoes aren't fully broken down before blending. For silky smooth results, simmer potatoes until they're completely tender (no resistance when pierced with a fork), then let the soup cool slightly before blending. If you're using a regular blender, work in batches and blend until completely smooth, then strain through a fine-mesh sieve if needed.
Can I use instant potato flakes instead of fresh potatoes?
Yes, but the texture will be slightly different. Use 1 cup instant potato flakes (about ¼ cup dry flakes) mixed with 1 cup hot broth> before adding to the pot. Cook for 10 minutes instead of simmering, then blend as usual. The flavor will be similar, but you'll lose that classic potato soup heartiness—fresh potatoes give the best results for that creamy, rustic texture.
How do I make this soup spicier?
Add heat with ½ teaspoon smoked paprika or ¼ teaspoon cayenne pepper when sautéing the onions. For depth, stir in 1 teaspoon hot sauce (like Tabasco) or ½ teaspoon chili flakes at the end. If you love bold flavors, try adding 1 diced jalapeño with the onions—remove seeds for milder heat. Always taste first and adjust gradually!
Can I double this recipe for a crowd?
Yes, but use a larger pot (at least 8-quart) to prevent overflowing. Double all ingredients exactly, but increase simmering time to 25-30 minutes to ensure even cooking. For serving, consider adding extra toppings like bacon bits or herbs—it's the perfect make-ahead dish for potlucks or family gatherings! Store leftovers in the fridge for up to 4 days.
