Step‑by‑Step Instructions for Potato Soup
Step 1: Prepare the Vegetables
Begin by peeling and dicing your russet potatoes and finely chopping the small onion. In a large stock pot or Dutch oven, combine the chopped potatoes and onions. Cover them with cold water, ensuring there is enough to submerge the vegetables completely, which will help them cook evenly.
Step 2: Cook Until Tender
Place the pot over medium-high heat and bring the water to a boil. Once boiling, reduce the heat slightly and let it simmer for about 15–20 minutes, or until the potatoes are fork-tender. You’ll know they are ready when you can easily pierce them with a fork without resistance.
Step 3: Drain Excess Water
Once the potatoes are tender, carefully drain the excess water from the pot, leaving about a cup of liquid to help create a creamy texture. The remaining water will assist in blending the flavors together beautifully, creating the perfect base for your creamy potato soup.
Step 4: Mash the Potatoes
Using a potato masher, mash the cooked potatoes and onions directly in the pot. Aim for a chunky consistency, breaking down the potatoes while still leaving some texture. This step is vital for achieving that beloved creamy potato soup feel, so take your time to get it just right.
Step 5: Add Butter and Milk
Stir in the butter and milk thoroughly until well combined. For an ultra-smooth finish, consider using an immersion blender at this stage, blending until you achieve your desired creaminess. Allow the mixture to come together over low heat as the ingredients meld into a comforting soup.
Step 6: Heat Through
Return the pot to medium heat and let the soup cook for an additional 6–7 minutes, stirring frequently to prevent sticking. Watching for small bubbles beginning to form is a good sign that your creamy potato soup is warming up beautifully and is nearly ready to serve.
Step 7: Season to Taste
Once heated through, season your potato soup with salt and pepper according to your preference. Stir the seasoning in well, ensuring each spoonful is bursting with flavor. Taste a small amount to adjust as needed, embracing the comforting richness that is sure to warm your heart.

Make Ahead Options
These creamy potato soup preparations are perfect for busy weeknights! You can peel and chop the russet potatoes and onion up to 24 hours in advance, storing them in a bowl of water in the refrigerator. This prevents browning and keeps them fresh. Additionally, you can prepare the butter and milk mixture, measuring them out and storing them separately within the same timeframe. When you’re ready to cook, simply drain the potatoes and onions, mash them with the remaining water, and stir in your pre-measured butter and milk. Finish cooking for that delightful creamy texture, ensuring dinner is just as delicious as if made from scratch in the moment!

4-Ingredient Creamy Potato Soup Recipe FAQs

I recommend using russet potatoes for their creamy consistency, but you can substitute with Yukon gold or red potatoes if you need to. Just keep in mind that other varieties may yield a slightly less creamy texture.
How long can I store potato soup in the refrigerator?
Your potato soup will stay fresh in an airtight container for up to 4 days. Make sure it cools down before sealing to lock in the best flavors and prevent spoilage.

This will help achieve that perfect creamy texture you desire!
