Cottage Cheese Mushroom Soup

Cottage cheese mushroom soup is one of those recipes that completely changed how I think about creamy soups. The first time I blended cottage cheese into a pot of earthy cremini mushrooms, I honestly wasn’t sure it would work. But the result was so silky and satisfying that it has been in my regular rotation ever since.

I still remember that chilly weeknight when I was staring at half a tub of cottage cheese and a bag of mushrooms, trying to avoid a grocery run. I threw it together out of necessity, and what came out of that blender stopped me in my tracks. This cottage cheese mushroom soup is deeply savory, surprisingly velvety, and loaded with protein. It proves that a wholesome, high-protein soup can be just as comforting as anything made with heavy cream.

What You Need to Make This Cozy Pot of Goodness

I always reach for cremini mushrooms here because they bring the deepest, most earthy flavor. That said, baby bella or a wild mushroom blend work just as well. Pro tip: do not rush the browning step. That golden color on the mushrooms is where the flavor really builds in this cottage cheese mushroom soup.

• 1 tablespoon olive oil or butter
• 1 small yellow onion, chopped
• 8 oz cremini mushrooms, sliced thin for easier blending
• 2 cloves garlic, minced
• 1/4 cup all-purpose flour
• 3 cups low-sodium chicken or vegetable broth (vegetable broth keeps it lighter and fully vegetarian)
• 1 cup low-fat cottage cheese (full-fat works too for an even richer result)
• 1/2 cup milk (any kind works – oat milk is a great dairy-free option)
• 1 teaspoon dried thyme
• Salt and black pepper to taste
• Fresh parsley for garnish (optional)

Pro tip: For the silkiest cottage cheese mushroom soup, use a high-speed blender rather than an immersion blender. The texture difference is real.

How to Make Cottage Cheese Mushroom Soup Step by Step

I recommend reading through all the steps before you start. This soup moves quickly once the mushrooms go in, and having everything prepped and measured ahead makes the process smooth.

Step 1: Heat the olive oil or butter in a large pot or Dutch oven over medium heat. Add the chopped onion and cook, stirring occasionally, until softened and translucent, about 4 to 5 minutes.

Step 2: Add the sliced mushrooms. Cook, stirring occasionally, until they release their liquid and begin to turn golden brown, about 8 to 10 minutes. Do not crowd the pan or stir too often – let them sit long enough to actually brown. This step is what gives your cottage cheese mushroom soup its deep, savory flavor.

Step 3: Stir in the minced garlic and dried thyme. Cook for about 1 minute until fragrant. Your kitchen should smell incredible right about now.

Step 4: Sprinkle the flour over the mushroom mixture. Stir constantly for 1 minute to cook out the raw flour taste. The mixture will look thick and paste-like. That is exactly right.

Step 5: Gradually pour in the broth while whisking continuously to prevent lumps. Bring the soup to a gentle simmer and cook for 5 to 7 minutes, stirring occasionally, until slightly thickened.

Step 6: Remove the pot from heat. Carefully transfer the soup to a countertop blender and add the cottage cheese. Blend until completely smooth and creamy, about 60 seconds. Important: always vent the blender lid slightly when blending hot liquids and cover with a folded towel to avoid pressure buildup. If using an immersion blender, blend directly in the pot, but note the texture may be slightly less smooth.

Step 7: Return the blended soup to the pot. Stir in the milk and season with salt and pepper. Warm gently over low heat until heated through, about 3 to 4 minutes. Do not bring it to a boil after adding the cottage cheese – the texture can turn grainy.

Step 8: Ladle into bowls and garnish with fresh parsley. Serve right away.

Keeping Your Soup Fresh: Storage and Reheating Tips

This cottage cheese mushroom soup stores well and honestly tastes even better the next day once the flavors have had time to settle. Transfer leftovers to an airtight container and refrigerate for up to 4 days.

To reheat, warm gently on the stovetop over low heat, stirring occasionally. If the soup has thickened overnight, stir in a splash of broth or milk to bring it back to your preferred consistency. Avoid microwaving on high heat, as this can affect the texture.

This soup can also be frozen for up to 3 months. I recommend portioning it into individual servings before freezing for easy weekday lunches. Pro tip: if the texture looks slightly separated after thawing, re-blend for 30 seconds and it will come right back together.
