Soups & Stews
This Weight Watchers potato soup recipe delivers all the creamy comfort of classic potato soup without the heavy guilt—perfect for cozy nights while staying on track. The secret lies in using Greek yogurt instead of heavy cream, creating a velvety texture with just 4 points per serving.
I developed this version after years of testing lighter alternatives that still satisfy cravings without compromising flavor.
The recipe builds on traditional techniques but swaps out high-calorie ingredients for smarter choices: low-fat chicken broth, reduced-sodium broth, and a blend of cheddar and Parmesan for depth.
Roasting the potatoes first intensifies their natural sweetness, while fresh herbs and a touch of mustard add bright, complex flavors that cut through the richness. What you get is a soup that feels indulgent but aligns with your goals.

Ingredients for weight watchers potato soup
Simple pantry staples that transform into creamy, guilt-free comfort. No heavy cream here—just smart swaps for flavor-packed goodness.
| Ingredient | Amount | Notes |
|---|---|---|
| Yukon Gold Potatoes 🥔 | 2 lbs | Cut into 1-inch cubes, roasted first |
| Plain Greek Yogurt 🥛 | 1 cup | 2% fat for creaminess without heaviness |
| Low-Fat Chicken Broth 💧 | 4 cups | Homemade or store-bought reduced-sodium |
| Reduced-Fat Cheddar Cheese 🧀 | ½ cup | Shredded, sharp variety preferred |
| Parmesan Cheese 🧀 | ¼ cup | Freshly grated for depth of flavor |
| Yellow Onion 🧅 | 1 whole | Diced, sweet variety like Vidalia |
| Garlic Cloves 🧄 | 3 cloves | Minced for aromatic base |
| Fresh Thyme Leaves 🌿 | 1 tbsp | Or 1 tsp dried thyme if fresh unavailable |
| Dijon Mustard 🍯 | 1 tbsp | For bright, tangy complexity |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For roasting potatoes |
| Sea Salt 🧂 | 1 ½ tsp | Adjust to taste, kosher preferred |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked for best flavor |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for fresh garnish |
| Whole-Grain Bread 🍞 | 4 slices | For serving, optional |
The potatoes are the star—Yukon Golds roast up perfectly caramelized and sweet. Trader Joe's or Whole Foods carry them fresh year-round, or grab the frozen bags at regular grocery stores. Roasting first brings out their natural sweetness, which balances the tangy mustard and herby notes. If you're prepping ahead, roast them the night before and store in the fridge—they'll be even sweeter. The Greek yogurt is non-negotiable for that velvety texture without the heaviness. Fage 2% or Siggi's plain are my go-tos—they stay thick when heated. For the broth, low-sodium options like Pacific Foods save you from adding extra salt later.
No Greek yogurt? Evaporated skim milk plus a splash of buttermilk gets you close, though the texture won't be as rich. Swap the cheddar for Monterey Jack if you're avoiding dairy, but you'll lose some sharpness. Fresh herbs make all the difference—if thyme is wilted, dried at one-third the amount works, but fresh is worth hunting down at the grocery store's produce section. The mustard adds that bright pop—Dijon is key (skip the sweet yellow stuff). For extra depth, add a pinch of smoked paprika when blending. And if you're watching points, skip the whole-grain bread or use just 2 slices per bowl.
This soup tastes even better the next day—reheat gently on the stove with a splash of broth to restore creaminess. Keeps 4-5 days in the fridge, or freeze portions for up to 3 months. I like to portion it into containers before freezing so I can grab and go. For meal prep, double the recipe and store in a big pot—just reheat and ladle. The herbs and mustard can be added fresh after reheating if you're serving immediately. Pro tip: save the potato water from boiling (if you boil any) and use it as extra broth—it's packed with starchy goodness.

Step-by-step instructions for Weight Watchers potato soup
Let's create a rich, creamy potato soup that delivers all the comfort without the guilt.
Roast the Potatoes for Depth of Flavor
Preheat your oven to 425°F. Cut the 2 lbs Yukon Gold Potatoes into 1-inch cubes and toss them with 1 tablespoon Extra-Virgin Olive Oil and ½ teaspoon Sea Salt. Spread them in a single layer on a baking sheet, leaving space between each cube.
Roast for 25-30 minutes until the edges are golden brown and the potatoes are tender when pierced with a knife. This roasting step develops a nutty sweetness that forms the base of our flavor. I like to flip them halfway through cooking to ensure even browning on all sides. The crispy edges will melt into the soup later, creating a luxurious texture.
Sauté Aromatics for the Foundation
While the potatoes roast, heat a large pot over medium heat. Add 1 tablespoon Extra-Virgin Olive Oil and the diced 1 whole Yellow Onion. Cook for 5-6 minutes until the onions are soft and translucent, stirring occasionally.
Add the 3 minced Garlic Cloves and 1 tablespoon Fresh Thyme Leaves, cooking for another 30 seconds until fragrant. You'll know it's ready when the kitchen fills with that aromatic garlic-thyme scent. This aromatic base is crucial—it's what makes homemade soup taste so much better than canned versions. If you're using dried thyme, add 1 teaspoon at this point.
Build the Creamy Base
Pour in the 4 cups Low-Fat Chicken Broth and bring to a gentle simmer. Add the roasted potatoes and 1 tablespoon Dijon Mustard. Let the mixture simmer for 10 minutes to allow the flavors to meld together. The mustard adds a subtle tang that brightens the richness of the soup.
Use an immersion blender to partially blend the soup until it reaches your desired creaminess. I like to leave some texture—just enough to break up the potatoes while keeping it rustic. If you don't have an immersion blender, carefully transfer about half the soup to a regular blender, blend until smooth, then return it to the pot. The soup should be thick but still spoonable.
Finish with Cheese and Herbs
Reduce the heat to low and stir in the 1 cup Plain Greek Yogurt and 0.5 cup Reduced-Fat Cheddar Cheese. Let it simmer gently for 2-3 minutes until the cheese is fully melted and the soup is heated through. The yogurt creates that silky texture without needing heavy cream.
Season to taste with additional Sea Salt and 0.5 teaspoon Ground Black Pepper, then stir in the 0.25 cup Fresh Parsley and 0.25 cup Parmesan Cheese. The parsley adds a fresh finish, while the Parmesan gives it that final cheesy punch. Taste again and adjust seasoning if needed—this is where you can really make the soup sing.
Serve with Crusty Bread
Ladle the soup into bowls and serve immediately with 4 slices Whole-Grain Bread on the side. The bread helps soak up any extra soup while adding a nice textural contrast. For an extra touch, sprinkle additional Parmesan Cheese and Fresh Parsley on top right before serving.
This soup delivers all the creamy comfort you crave while staying light enough for your Weight Watchers plan. The roasted potatoes add depth, the yogurt keeps it rich without being heavy, and the fresh herbs brighten everything up. Enjoy it warm on a chilly day—it's the perfect balance of comfort and nutrition.
Pro Tips For Making Weight Watchers Potato Soup
- Peel and Cube Evenly: DESCRIPTION: Yukon Golds are forgiving, but cut them into 1-inch chunks—no smaller, or they’ll turn to mush. I learned this the hard way when my first batch dissolved into a gluey mess. (Yes, even if you’re impatient like me, resist the urge to rush this.)
- Simmer, Don’t Boil: DESCRIPTION: After adding broth, keep the heat at a gentle simmer—not a rolling boil. I used to crank it up, and the yogurt would split like a bad soufflé. A low simmer (barely bubbles) keeps the soup creamy and the potatoes intact.
- Temper the Yogurt: DESCRIPTION: Warm the broth first, then slowly stir in the yogurt while the soup’s still hot. Cold yogurt dumped in will curdle faster than you can say “weight watchers.” I now mix a spoonful of hot broth into the yogurt first—works every time.
- Cheese in Layers: DESCRIPTION: Sprinkle the reduced-fat cheddar first, stir until melted, then top with Parmesan. This prevents a grainy texture—cheddar’s heavier, so it sinks if you mix it all at once. (Pro move: grate the Parmesan fresh if you’re feeling fancy.)
Storing and reheating this weight watchers potato soup
Refrigerator Storage
Store your Weight Watchers potato soup in an airtight container (I use glass Pyrex with snap-on lids) for up to 4-5 days in the fridge. Let it cool completely first to prevent condensation, which can dilute flavors.
The soup actually tastes better the next day as the flavors meld together—this is when the roasted potato sweetness really shines. 🥣
Portion into single-serving containers if meal prepping, which makes reheating a breeze. I like to use 16-ounce glass containers for easy grab-and-go lunches. Remember, the yogurt may thicken slightly overnight—just stir in a splash of broth when reheating to restore creaminess.
Freezer Prep Tips
For long-term storage, freeze portions in quart-sized freezer bags or glass containers with 1-inch headspace to allow for expansion. Seal tightly to prevent freezer burn, which can make the soup taste stale. Label with the date—this soup stays delicious for up to 3 months in the freezer. 🧊
For best results, freeze the soup after adding the fresh herbs and mustard. When you're ready to eat, simply thaw overnight in the fridge and reheat gently. The texture may separate slightly, but a quick stir with a splash of broth brings it back together beautifully.
Stovetop Reheating
My preferred method is reheating on the stovetop over medium-low heat—this preserves the creamy texture better than microwaving. Pour the soup into a heavy-bottomed pot and add 2-3 tablespoons of low-fat chicken broth to prevent sticking. Stir occasionally for 5-7 minutes until heated through to 165°F. 🔥
Taste and adjust seasoning after reheating—the flavors can mellow out slightly. A pinch of Dijon mustard or salt can brighten it right up. If the soup looks too thick, add a little more broth to reach your desired consistency.
Microwave Safety
For quick reheating, transfer soup to a microwave-safe bowl and cover loosely with a microwave-safe lid or damp paper towel. Heat on medium power (50-70%) in 1-minute intervals, stirring between each, until hot throughout. Avoid high power to prevent scorching the bottom. ⚡
If the soup separates after microwaving, stir vigorously and add a splash of warm broth to restore creaminess. For extra flavor, sprinkle with fresh parsley or a dash of black pepper after reheating—this makes it taste fresh again.

Frequently asked questions
How many Weight Watchers points does one serving have?
This recipe yields about 4 points per serving (without bread) when using the current WW program's personal points system. The Greek yogurt and reduced-fat cheeses keep it light while delivering satisfying creaminess. For a complete breakdown, check your WW app with the exact ingredients you use.
Can I make this soup dairy-free?
Yes! Replace the Greek yogurt with 1 cup unsweetened almond milk and use ½ cup nutritional yeast instead of cheese for a cheesy flavor without dairy. The texture will be slightly thinner, but still delicious. The mustard and thyme will still provide that rich depth.
Why does my soup look too thick after reheating?
This happens because the Greek yogurt separates when cooled. Simply stir in 1-2 tablespoons of warm broth and heat gently until smooth. The yogurt will re-emulsify beautifully. For extra insurance, whisk in a splash of broth before storing leftovers in the fridge.
What's the fastest way to make this recipe?
Skip roasting the potatoes: boil them whole for 15 minutes, then mash them directly into the soup. Use pre-minced garlic and dried thyme to save 10 minutes of prep. The flavor will be slightly different but still comforting and satisfying.
Can I add meat to this Weight Watchers potato soup?
Add ½ lb cooked chicken breast (about 2 points) or 4 oz lean ground turkey (about 3 points) to each serving. Brown the meat first with the onions for maximum flavor. For a vegetarian option, stir in ½ cup lentils (about 1 point) when reheating.
