Potato Soup Cream of Mushroom Recipe (35-Min) – Creamy & Hearty
A can of condensed soup is the starting point, but sautéing onion, garlic, and fresh mushrooms first builds real flavor underneath the creamy base, and mashing part of the potatoes at the end gives this soup its classic thick, chunky texture. It comes together in about 35 minutes with basic pantry ingredients, making it an easy weeknight dinner when you want something warm and filling without much effort.
Ingredients
- 2 tbsp butter
- 1/2 cup diced onion
- 2 cloves garlic, minced
- 8 oz sliced mushrooms
- 2 lbs russet potatoes, peeled and diced
- 3 cups chicken or vegetable broth
- 1 can (10.5 oz) condensed cream of mushroom soup
- 1 cup whole milk
- Salt and pepper, to taste
- Shredded cheddar, cooked bacon bits, and sliced chives, for topping
Instructions
- Melt the butter in a large pot over medium heat. Add the onion and cook until softened, about 4 to 5 minutes.
- Add the garlic and mushrooms. Cook, stirring occasionally, until the mushrooms release their liquid and start to brown, about 5 to 6 minutes.
- Add the diced potatoes and broth. Bring to a boil, then reduce the heat and simmer until the potatoes are fork-tender, 15 to 18 minutes.
- Reduce the heat to low, then stir in the condensed cream of mushroom soup and milk until fully combined and heated through, 3 to 4 minutes.
- For a thicker, creamier texture, mash some of the potatoes against the side of the pot with the back of a spoon, leaving the rest chunky.
- Taste and season with salt and pepper as needed.
- Ladle into bowls and top with shredded cheddar, bacon bits, and chives.
Why This Potato Soup Cream of Mushroom Recipe Works
Condensed cream of mushroom soup does the heavy lifting on thickness and creaminess, which is what makes this such a fast weeknight dinner — there’s no separate roux or cream reduction to manage. Sautéing the onion, garlic, and fresh mushrooms before adding the broth builds a layer of real, browned flavor underneath the canned soup, so the finished pot tastes like more than the sum of its ingredients. Mashing a portion of the cooked potatoes at the end thickens the soup naturally and gives it the classic loaded-potato-soup texture, while leaving some potato pieces whole keeps every spoonful interesting.
Tips for the Best Potato Soup
Russet potatoes break down more easily than waxy varieties, which is exactly what you want for a creamy, thick soup like this one. This potato soup cream of mushroom recipe is forgiving, but taste before adding salt — condensed soup and broth are both already seasoned, so it’s easy to over-salt if you season by habit instead of by taste. If you want an even more mushroom-forward soup, use a full pound of mushrooms instead of 8 ounces, or add a splash of the mushroom soaking liquid if you’re using dried mushrooms alongside the fresh ones.
Common Mistakes to Avoid
Adding the milk while the soup is still at a hard boil can cause it to curdle or separate — always drop the heat to low first, as this recipe does in step 4. Skipping the sauté step and just dumping everything into the pot at once will get you a technically edible soup, but one that tastes flat and mostly like the can it came from. Boiling the potatoes too long past fork-tender turns them waterlogged and mushy rather than creamy, so start checking a couple of minutes before the recipe’s estimated time.
What to Serve With Potato Soup
A loaf of crusty bread or warm dinner rolls for dipping is the classic pairing here. A simple green salad with a sharp vinaigrette also balances out the richness of the soup nicely. If you’re serving a crowd, set out toppings like extra cheddar, bacon bits, sour cream, and chives so everyone can customize their own bowl.
Storage
Store leftover potato soup cream of mushroom in an airtight container in the refrigerator for up to 4 days. Reheat gently over low heat on the stovetop, stirring occasionally — dairy-based soups like this one can separate if reheated too quickly at high heat. This soup isn’t a great candidate for freezing, since the milk and condensed soup base tend to separate and turn grainy once thawed.
Frequently Asked Questions
Can I make this potato soup vegetarian? Yes — use vegetable broth in place of chicken broth, and double-check that your condensed cream of mushroom soup brand doesn’t contain any meat-based stock, since some do.
Can I use homemade cream of mushroom soup instead of canned? Yes, about 1 1/4 cups of homemade cream of mushroom soup can replace the canned version. You may want to reduce the added salt slightly, since homemade versions are often less salty than canned.
Can I freeze potato soup? It’s not ideal — the dairy in this soup tends to separate and turn grainy after freezing and thawing. If you want to make it ahead, you can freeze the sautéed vegetables and cooked potatoes in broth, then stir in the soup and milk fresh after thawing and reheating.
What’s the difference between this and a cream of potato soup? This potato soup cream of mushroom recipe differs from a straight cream of potato soup, which is built entirely around potatoes and cream, while this version leans on condensed cream of mushroom soup for its base, which adds a layer of mushroom flavor and cuts down on the hands-on cooking time.
