This mushroom soup without cream gets its creamy texture from a small potato and partially blended mushrooms. Browned cremini mushrooms, onion, garlic, and thyme give the soup a savory flavor without milk, butter, or flour.
Leave some mushroom pieces intact for texture, or blend more for a smoother bowl. Serve with crusty bread for a simple fall lunch or a light dinner.

Why This Mushroom Soup Without Cream Works
The mushrooms provide flavor, while the potato gives the broth body after blending. You do not need a flour-thickened sauce or a cream substitute.
The most useful step happens before adding the broth: let the mushrooms release their moisture, then continue cooking until the liquid evaporates and the edges begin to brown. Adding broth too early leaves you with a milder soup.
Partial blending lets you keep both a creamy base and visible mushroom pieces. You can adjust the finished consistency with a little extra broth.
Easy Mushroom Soup Without Cream (One Pot)
Equipment
- Wide heavy pot or Dutch oven
- Cutting board
- Sharp knife
- Wooden Spoon
- Immersion blender
- Measuring cups and spoons
- Food thermometer
Ingredients
- 3 tablespoons olive oil
- 1 medium yellow onion diced
- 1 pound cremini mushrooms cleaned and sliced ¼ inch thick
- 3 garlic cloves minced
- 1 teaspoon fresh thyme leaves or ½ teaspoon dried thyme
- 1 small Yukon Gold potato about 6 ounces, peeled and cut into ½-inch cubes
- 4 cups low-sodium vegetable broth plus more to adjust consistency
- ½ teaspoon fine salt plus more to taste
- ¼ teaspoon freshly ground black pepper plus more to taste
- Optional Garnish Fresh thyme leaves
Instructions
- Heat the olive oil in a wide, heavy pot over medium heat. Add the diced onion and cook for about 4 minutes, stirring occasionally, until softened.
- Add the sliced mushrooms and increase the heat to medium-high. Cook for about 12–15 minutes, stirring occasionally, until their released liquid evaporates and some edges begin to brown. If the pot is narrow, cook the mushrooms in batches; this may take longer.
- Reserve about ¼ cup of browned mushroom slices for serving. Add the garlic and thyme to the pot and stir for 30 seconds.
- Add the diced potato, vegetable broth, salt, and pepper. Scrape up the browned bits from the bottom of the pot.
- Bring to a gentle boil, then reduce the heat. Simmer partially covered for about 15–18 minutes, until the potato cubes are fork-tender.
- Remove the pot from the heat. Use an immersion blender to partially blend the soup, keeping the blade submerged. Stop when the broth is creamy but some mushroom pieces remain. Avoid prolonged blending.
- Stir and taste. Adjust the salt and pepper. If the soup is too thick, add extra broth a few tablespoons at a time.
- Warm gently if needed. Divide among four bowls and top with the reserved mushrooms and optional fresh thyme leaves.
Notes
Ingredients for Mushroom Soup Without Cream
Cremini mushrooms: Use 1 pound of fresh mushrooms, sliced about ¼ inch thick. White button mushrooms also work, or replace part of the cremini with sliced shiitake caps.
Olive oil: Helps cook the vegetables and adds richness without butter.
Yellow onion and garlic: Build the flavor of the soup. Cook the onion until softened and add the garlic briefly before the broth.
Yukon Gold potato: One small peeled potato, about 6 ounces, thickens the soup after blending. Cut it into ½-inch cubes so it cooks evenly.
Vegetable broth: Choose low-sodium broth so you can control the seasoning. Broths vary in flavor and salt content.
Thyme: Use fresh thyme leaves or a smaller amount of dried thyme. Keep woody stems out of the soup.
Salt and black pepper: Start with the recipe amounts, then adjust after blending.
Tips for a Creamy, Flavorful Mushroom Soup
- Dry the mushrooms after cleaning. Excess water delays browning.
- Wait for the mushroom liquid to evaporate. Look for browned edges before adding broth.
- Keep the potato amount modest. Too much can overpower the mushroom flavor.
- Check the potato before blending. Undercooked cubes will not produce a smooth base.
- Blend gradually. You can always blend more if you prefer fewer pieces.
- Season after blending. Taste the finished soup before adding extra salt.

Variations and Substitutions
Different mushrooms: Combine cremini and white button mushrooms. Shiitake caps add another texture; remove their tough stems.
Chicken broth: Substitute low-sodium chicken broth in the same amount. The soup will remain dairy-free but will no longer be vegan.
No fresh thyme: Use ½ teaspoon dried thyme instead of 1 teaspoon fresh thyme leaves.
Smoother soup: Blend more of the soup, stopping once it reaches the texture you prefer.
No potato: You can omit it, but the soup will have less body. Blend some mushrooms and begin with 3 cups of broth, adding more as needed.
Gluten-free version: The recipe contains no flour. Check the broth and other packaged ingredient labels, and serve with gluten-free bread if needed.
How to Store and Reheat Mushroom Soup
Divide leftovers into shallow containers and refrigerate within 2 hours, or within 1 hour when the surrounding temperature exceeds 90°F (32°C).
Keep refrigerated soup for 3–4 days. Reheat while stirring until it reaches 165°F (74°C), following the USDA leftovers guidance. Add broth if the soup has thickened.
You can freeze portions, leaving room for expansion. Thaw in the refrigerator and stir well while reheating; the texture may change slightly.
Troubleshooting Your Mushroom Soup
| Problem | What to do |
|---|---|
| Too thick | Stir in warm broth a few tablespoons at a time. |
| Too thin | Blend a little more, or simmer uncovered briefly while stirring. |
| Bland flavor | Taste for salt first. Next time, allow more mushroom browning before adding broth. |
| Potato pieces remain firm | Continue simmering until fork-tender before blending. |
| Texture becomes gummy | Stop blending. Stir in a little broth; prolonged blending can affect potato texture. |
Frequently Asked Questions
How does mushroom soup become creamy without cream?
The cooked potato and some of the mushrooms blend into the broth, creating body without dairy or flour.
Can I use white button mushrooms?
Yes. Use the same weight and allow their released moisture to evaporate before adding the broth.
Is this mushroom soup vegan?
Yes, when you use vegan vegetable broth. The recipe contains no milk, butter, or cheese.
Do I need an immersion blender?
No. A countertop blender can work if you follow its instructions for hot liquids. Blend small batches and return them to the pot.
Can I leave the soup completely chunky?
Yes, but the broth will be thinner. Mash some cooked potato against the side of the pot if you want a little more body without blending.
Can I prepare mushroom soup without cream ahead?
Yes. Refrigerate promptly and reheat before serving. Add a splash of broth if it thickens during storage.
Can I use this instead of canned condensed mushroom soup?
Not as a direct replacement. This recipe makes ready-to-eat soup, which contains more liquid than condensed soup and can change a casserole’s consistency.
