Ingredients You’ll Need

This Four Ingredient Potato Soup is all about simplicity meeting flavor. Each ingredient plays its part beautifully, from the tender potatoes that give the soup its body to the onion’s aromatic sweetness and the smooth tang of Greek yogurt that adds richness without heaviness.

Olive oil: Using a good quality olive oil adds a subtle fruity note while perfectly sautéing the onion for that great base flavor.
Yellow onion: Diced finely, it softens during cooking and provides a gentle, natural sweetness that balances the potatoes.
Russet potatoes: Peeled and cubed, these starchy potatoes break down to create the soup’s creamy texture without needing any cream.
Vegetable broth (or chicken broth): Adds depth and warmth to the soup, creating a flavorful yet light liquid base that lets the potatoes shine.
Plain Greek yogurt: Whisked with a bit of warm water for creaminess, this ingredient keeps the soup luscious and tangy, giving it that perfect finish.
Salt and pepper: Essential seasonings for bringing all the flavors together and enhancing every spoonful.

How to Make Four Ingredient Potato Soup

Step 1: Sauté the Onion

Start by warming the olive oil in a heavy pot or Dutch oven over medium heat. Toss in your diced yellow onion and sauté gently for about five minutes until it becomes translucent and fragrant. This step is crucial as it builds the flavor foundation for the soup — that soft, slightly sweet onion flavor is what makes the finished dish so comforting.

Step 2: Add Potatoes and Broth

Next, add your peeled and cubed russet potatoes to the pot, followed by four cups of your chosen vegetable or chicken broth. Stir everything together, then bring the mixture to a gentle simmer. Cover and cook on medium-low for roughly 20 minutes, or until the potatoes are tender enough to pierce easily with a fork. This is the moment where the potatoes start to soak up that savory broth goodness.

Step 3: Incorporate the Greek Yogurt

While the potatoes are cooking, whisk the plain Greek yogurt with a quarter cup of warm water to loosen it up — this keeps the soup creamy without curdling. Once the potatoes are done, slowly pour this yogurt mixture into the pot, stirring to combine smoothly. This accidental twist keeps your Four Ingredient Potato Soup indulgently creamy but light on the stomach, which is just brilliant.

Step 4: Blend Until Smooth

Now comes the fun part — blending the soup to silky perfection. Using an immersion blender right in the pot is easiest and less messy, but you can also carefully transfer the soup to a regular blender in batches. If you’re blending hot soup in a traditional blender, always leave the lid slightly loosened to let steam escape safely. Blend until you have a beautiful, velvety texture that’s invitingly smooth.

Step 5: Adjust Thickness and Season

After blending, whisk in an additional one to two cups of broth to reach your desired soup thickness. Now is the time to add salt and pepper to taste — don’t be shy with this since it really brings out the flavors and makes your Four Ingredient Potato Soup sing. Give it a final stir and get ready to serve!

How to Serve Four Ingredient Potato Soup

Garnishes

While the soup itself is deliciously simple, a few garnishes can elevate it to something special. Think shredded sharp cheddar cheese melting over the top, crispy bacon bits for a salty crunch, or a sprinkle of fresh parsley for a burst of color and freshness. These garnishes add texture and extra layers of flavor that turn the humble soup into a real showstopper.

Side Dishes

Pair your Four Ingredient Potato Soup with a warm, crusty bread or a fresh green salad to round out the meal. Garlic bread or a soft dinner roll with butter are fantastic for dunking and soaking up every creamy drop. For a lighter side, crisp veggies or even roasted Brussels sprouts make lovely companions that complement the soup’s comforting richness without overwhelming it.

Creative Ways to Present

Want to impress guests with presentation? Serve your Four Ingredient Potato Soup in rustic bread bowls for a fun twist that’s both edible and charming. Alternatively, pour it into pretty bowls and drizzle a streak of olive oil or swirl some extra yogurt on top. Adding a pinch of smoked paprika or chives can add a pop of color and hint at flavors to come, making every serving feel special and thoughtfully prepared.

Make Ahead and Storage

Storing Leftovers

This soup keeps beautifully in the fridge for up to four days. Store it in an airtight container to maintain freshness. Before storing, give it a quick stir to keep everything well combined, and be sure the soup has cooled to room temperature to avoid condensation inside the container.

Freezing

You can freeze the Four Ingredient Potato Soup for up to three months, making it a perfect make-ahead meal for busy weeks. Portion it out into freezer-safe containers or bags, leaving some space for expansion. When you’re ready to enjoy, thaw overnight in the fridge before reheating gently on the stove.

Reheating

Reheat the soup slowly on low heat, stirring regularly to prevent sticking or scorching at the bottom. If the soup has thickened too much after chilling, simply add a splash of broth or water to bring it back to the ideal creamy consistency. Avoid boiling once reheated to keep the yogurt smooth and prevent curdling.

FAQs

Can I use a different type of potato for this soup?

Russet potatoes are ideal because of their high starch content, lending creaminess without extra ingredients. However, Yukon Gold potatoes can also work well and might add a richer flavor, though the texture could be slightly less silky.

Is Greek yogurt necessary in the Four Ingredient Potato Soup?

Greek yogurt adds a tangy creaminess and helps keep the soup light. If you need a dairy-free option, you can try coconut yogurt, but this will change the flavor and texture somewhat.

Can I make this recipe vegan?

Absolutely! Use vegetable broth and substitute the Greek yogurt with a dairy-free alternative like cashew cream or a plant-based yogurt to keep it vegan-friendly while maintaining that creamy texture.

How can I thicken the soup if it’s too thin?

If your soup seems too runny, simmer it a bit longer uncovered to reduce and thicken naturally. Alternatively, add a small amount of mashed potato or a cornstarch slurry to achieve your preferred consistency.

Can I prepare any steps in advance?

You can sauté the onions and prep the potatoes a day ahead, storing them separately in the fridge. Just combine everything and cook when you’re ready. This makes the cooking process faster without sacrificing flavor.
