Comfort food doesn’t require heavy cream to be satisfying. This low-fat potato soup delivers velvety texture and rich flavor through smart cooking techniques and simple ingredients.
By puréeing part of the soup and using low-fat dairy, you achieve a creamy consistency without excess fat. The result is a hearty, warming dish that’s light yet deeply flavorful.
Ingredients for Low Fat Cream of Potato Soup
Simple ingredients transform into a velvety soup with rich flavor and satisfying texture.
| Ingredient | Amount | Notes |
|---|---|---|
| Yukon Gold Potatoes 🥔 | 2 lb | Peeled and diced evenly |
| Low-Fat Milk 🥛 | 2 cups | 2% or skim for lighter texture |
| Vegetable Broth 🥕 | 4 cups | Low-sodium preferred for control |
| Yellow Onion 🧅 | 1 whole | Medium, finely diced |
| Celery Stalks 🌿 | 2 whole | Diced for aromatic base |
| Garlic Cloves 🧄 | 3 cloves | Minced for depth of flavor |
| Unsalted Butter 🧈 | 1 tbsp | For sautéing vegetables |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening the soup |
| Low-Fat Sour Cream 🥣 | ½ cup | For creamy finish (optional) |
| Fresh Thyme Leaves 🌿 | 1 tbsp | Chopped, or 1 tsp dried |
| Bay Leaf 🍃 | 1 whole | Dried, for simmering |
| Salt 🧂 | 1 tsp | Kosher or sea salt preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground for best flavor |
| Fresh Chives 🌿 | 2 tbsp | Chopped, for garnish |
The potatoes are the foundation—Yukon Golds bring natural creaminess without added fat. For best texture, dice them uniformly (about 1-inch cubes). Whole Foods or any well-stocked market will carry quality Yukon Golds. The vegetable broth should be low-sodium so you control the seasoning. Avoid pre-diced potatoes; they oxidize quickly and lack freshness.
For substitutions, russet potatoes work but require more blending for smoothness. No low-fat milk? Use unsweetened almond milk with a splash of lemon for tang. Chicken broth can replace vegetable broth if dietary restrictions allow. The flour can be swapped for cornstarch at half the quantity for a gluten-free option. Fresh herbs are ideal, but dried work at one-third the amount.
Store potatoes in a cool, dark place for up to 2 weeks. The soup keeps 4-5 days refrigerated or freezes beautifully for 3 months. Reheat gently to maintain the velvety texture without curdling the dairy.

Step-by-Step Instructions for Cream of Potato Soup
This method ensures a velvety texture and rich flavor while keeping it light and satisfying.
Step 1: Sauté the Aromatic Base
In a large pot, melt the 1 tbsp Unsalted Butter over medium heat. Add the 1 whole Yellow Onion and 2 whole Celery Stalks, both finely diced as specified. Sauté for 5-7 minutes until the vegetables soften and the onion becomes translucent.
Stir in the 3 cloves Garlic Cloves, minced, and cook for an additional 30 seconds until fragrant. This builds the flavor foundation for your soup. Be careful not to let the garlic brown, as it can turn bitter.
Add the 1 tbsp Fresh Thyme Leaves and 1 whole Bay Leaf to the pot, stirring to combine. These herbs will infuse the soup with depth as it simmers.
Step 2: Thicken and Simmer the Soup Base
Sprinkle the 2 tbsp All-Purpose Flour over the sautéed vegetables and stir to coat evenly. Cook for 1-2 minutes to remove the raw flour taste, which creates a light roux for thickening.
Gradually pour in the 4 cups Vegetable Broth, whisking constantly to prevent lumps from forming. Bring the mixture to a gentle boil, then reduce the heat to medium-low and let it simmer for 5 minutes.
Add the 2 lb Yukon Gold Potatoes, peeled and diced evenly, along with the 1 tsp Salt and 0.5 tsp Black Pepper. Simmer for 15-20 minutes until the potatoes are fork-tender.
Step 3: Blend and Finish with Creaminess
Using an immersion blender, purée the soup directly in the pot until smooth and velvety. If you don’t have an immersion blender, carefully transfer the soup in batches to a standard blender, then return it to the pot.
Stir in the 2 cups Low-Fat Milk and warm the soup over low heat for 3-5 minutes. Avoid boiling to prevent the milk from curdling. The soup should be creamy and well combined at this stage.
For the final touch, remove the pot from heat and stir in the 0.5 cup Low-Fat Sour Cream until fully incorporated. This adds a luscious creaminess without the heavy calories.
Step 4: Adjust and Serve
Taste the soup and adjust the seasoning if needed, though the 1 tsp Salt and 0.5 tsp Black Pepper should provide a balanced base. If the soup is too thick, thin it with a splash of additional Vegetable Broth or Low-Fat Milk.
Ladle the soup into bowls and garnish with the 2 tbsp Fresh Chives, chopped. The chives add a pop of color and a mild oniony freshness that complements the creamy soup perfectly.
Serve immediately while hot, with crusty bread or a light salad on the side for a complete, comforting meal.
Pro Tips For Making Low Fat Cream Of Potato Soup
- Simmer Gently: Keep the heat at a low simmer once the potatoes are in—boiling aggressively breaks them down too much, and you’ll end up with gluey soup instead of creamy.
- Peel After Cooking: Yukon Golds have thin skins, so cook them whole or halved, then peel after. It saves time and keeps more potato in the pot where it belongs.
- Skip Raw Flour: If you’re using a little flour to thicken, cook it with the onions and celery first. Adding it raw to the soup gives a pasty, uneven texture that’s hard to fix.
- Warm the Milk: I learned this the hard way—adding cold low-fat milk straight to hot soup can cause curdling. Warm it in the microwave for 30 seconds first, then stir it in slowly.
Storing and Reheating This Dish
Refrigerator Storage
Let the soup cool for no more than 2 hours before transferring to airtight containers. I use glass Pyrex for easy reheating. Store at 40°F or below for up to 4-5 days. The flavors deepen overnight. ❄️
Freezer Storage
This soup freezes beautifully for up to 3 months without texture loss. Use quart-sized freezer bags laid flat to save space. Leave 1 inch headspace for expansion and remove excess air to prevent freezer burn.
Stovetop Reheating
Warm over medium-low heat in a heavy pot, stirring occasionally. Add ¼ cup milk or broth if too thick. Heat until steaming, about 10-12 minutes. Avoid boiling to prevent curdling. 🔥
Microwave Reheating
Transfer a single portion to a microwave-safe bowl and cover loosely. Heat on 70% power for 2-3 minutes, stir, then continue in 30-second bursts until reaching 165°F.
Thawing Frozen Soup
Thaw overnight in the refrigerator for best texture. For quick thawing, use the defrost setting on your microwave, then reheat using one of the methods above. Stir well after thawing.

Frequently Asked Questions
Can I use a different type of potato?
Yes, but Yukon Golds are ideal for natural creaminess. Russets work but need more blending. Avoid waxy red potatoes as they won’t purée smoothly.
Why does the soup curdle sometimes?
Curdling happens if the milk boils. Always warm it over low heat and stir constantly. Adding a splash of cold milk at the end can help stabilize it.
Can I make this soup vegan?
Swap the milk for unsweetened almond milk and use vegan butter. Skip the sour cream or use a dairy-free alternative.
How do I make it thicker without extra fat?
Blend more of the potatoes or add an extra 1 tbsp flour when making the roux. A splash of low-sodium broth can adjust thinness without adding fat.
