Potato Soup Recipe With Cream Of Mushroom Soup: Velvety Comfort with Earthy Depth

This potato soup delivers velvety comfort with a rich, earthy twist that sets it apart from ordinary versions. The addition of cream of mushroom soup creates a deep, savory base that enhances the natural sweetness of the potatoes.

I developed this recipe for those chilly evenings when you need something hearty yet effortless. The cream of mushroom soup adds body and umami without complicated techniques, making it foolproof for any home cook.

Each spoonful offers tender potato chunks in a creamy, flavorful broth. The result is a satisfying bowl of soup that feels indulgent but comes together with minimal effort.

Perfect for weeknight dinners or cozy weekends. Here’s how to make it.

Ingredients for Potato Soup Recipe with Cream of Mushroom Soup

Pantry staples and fresh veggies come together for this cozy, satisfying bowl.

The potatoes are the heart of this. Russets give that perfect fluffy texture—don’t sub with waxy red potatoes. Costco has great 5-lb bags for a steal. For the cream of mushroom soup, Campbell’s is classic, but Progresso has a richer flavor (and their organic line is even better). The veggies? Any grocery store’s produce section works, but farmers market carrots and celery have more punch.

No cream of mushroom on hand? Cream of chicken works in a pinch (just check it’s vegetarian). Swap the milk for half-and-half if you want it extra indulgent. Fresh thyme is a game-changer if you’ve got it—use one-third the amount of dried. The butter can be margarine, but honestly real butter tastes better. Low on time? Pre-diced mirepoix (onion, celery, carrot) from Trader Joe’s saves a step.

This soup tastes even better the next day. Keeps for 4-5 days in the fridge, or freeze for 3 months. Reheat gently on the stove—microwaving can separate the cream. Leftovers make great lunch the next day (trust me, it’s even more flavorful).

Step-by-Step Instructions for Potato Soup with Cream of Mushroom Soup

This method builds deep flavor in layers while keeping the process simple and satisfying.

Step 1: Sauté the Aromatic Base

Heat 2 tbsp unsalted butter in a large pot over medium heat until melted. Add the finely diced yellow onion, celery stalks, and carrots. Cook for 8-10 minutes, stirring occasionally, until the vegetables soften and the onion becomes translucent.

Add the 3 cloves minced garlic cloves and cook for 1 minute until fragrant. I always keep the heat at medium to prevent the garlic from burning, which would add bitterness. You’ll know it’s ready when the mixture smells rich and the edges of the vegetables start to turn light golden brown.

Step 2: Create the Roux and Build the Soup Base

Stir in the remaining 2 tbsp unsalted butter until melted. Sprinkle the 3 tbsp all-purpose flour over the vegetables and stir constantly for 2 minutes to cook the raw flour taste out. This creates a roux that will thicken the soup beautifully.

Slowly pour in the 4 cups vegetable broth, whisking continuously to prevent lumps. Add the 1 can cream of mushroom soup, 1 tsp dried thyme, and 1 whole bay leaf. Stir well to combine, then bring the mixture to a gentle simmer.

Step 3: Add Potatoes and Simmer Until Tender

Add the 2 lb diced russet potatoes, 1.5 tsp kosher salt, and 0.5 tsp ground black pepper. Stir to coat the potatoes in the broth. Bring the soup back to a simmer, then reduce the heat to medium-low.

Cover and let it cook for 15-20 minutes, stirring occasionally, until the potatoes are fork-tender. You’ll notice the potatoes start to break down slightly at the edges—that’s perfect. They’ll help thicken the soup naturally as they cook.

Step 4: Finish with Dairy for Creamy Luxury

Stir in the 2 cups whole milk and 0.5 cup heavy cream. Cook for an additional 5 minutes over low heat, stirring occasionally. This allows the flavors to meld together while the milk and cream warm through. Don’t let it boil—just heat it until it’s steaming hot.

Remove the bay leaf and taste. Adjust the seasoning with more kosher salt or ground black pepper if needed. The soup should be velvety smooth with a rich, earthy depth from the cream of mushroom soup.

For a thicker consistency, gently mash a few potatoes against the side of the pot with a wooden spoon. This releases their starch and creates an even creamier texture without needing extra thickeners.

Flavor Customization for This Dish

Cheesy Upgrade

Stir in 1 cup shredded sharp cheddar during the final 5 minutes of cooking for a rich, tangy depth. I love using Cabot brand for its bold flavor. The cheese melts beautifully into the creamy base.

Herb Enhancements

Add 1 tsp rosemary or 1 tbsp fresh parsley with the thyme for extra aromatic complexity. Fresh herbs brighten the earthy mushroom notes. I often tie rosemary sprigs with kitchen twine for easy removal.

Spicy Kick

For heat, add ½ tsp cayenne pepper or 1 diced jalapeño with the onions. The spice cuts through the creaminess perfectly. I prefer the cayenne for even heat distribution. 🌶️

Smoky Flavor

Incorporate ½ tsp smoked paprika when adding the flour for a subtle wood-fired taste. This pairs wonderfully with the cream of mushroom base. I use Penzeys for the best quality.

Alternatively, crumble 2 strips cooked bacon on top when serving for a crispy, smoky garnish.

Extra Creaminess

Replace ½ cup milk with ½ cup sour cream for extra tang and thickness. Stir it in at the very end to prevent curdling. This makes the soup even more indulgent. 💛
