Gluten-Free Creamed Mushroom Soup with Toasted Herb Croutons

Today is my Mom Penny’s birthday! Instead of cake, I’ve made her a heartwarming soup—mostly because it reminds me of her. It takes me back to the time when my Dad went on business trips and Mom would pull out the Campbell’s (or the Stouffer’s). Believe it or not, that was pure comfort to my older brother, Bernardo, and me. Maybe because Mom typically cooked every single day: breakfast, lunch, dinner. And don′t forget snack—what service we′d get when we returned home from school! Spoiled, we were! Thanks, Mom, and have the happiest of birthdays! Love, Silvana

Playing around in the kitchen while I soften the onions in butter for about 5 minutes, then I transfer them to a plate…

…and add some more butter to cook the mushrooms in until they’ve softened and all the liquid has evaporated, about 15 minutes. Then I return the onions to the pan,…

…stir in the broth and bring the mixture to a boil. If you want to keep it vegetarian, use vegetable broth. Otherwise, chicken broth works well here, too. I lower the heat and simmer for about 15 minutes.

Then I add the cream, salt and pepper, and cook until heated through, but I do not let it come to a boil or it could curdle.

I transfer half of the mixture to a blender and puree it. Be careful when you blend hot liquids. I like to cover the lid with a dishtowel to avoid any hot splatters.

I return the blended mixture to the pan and keep the soup, covered, warm over low heat.

To make the herb croutons, I stir together melted butter (you could use olive oil here, too) and a mix of fresh herbs.

Then drizzle the herb butter over the bread cubes, season with salt and pepper and toss to coat. I like to use my hands, but a wooden spoon works just fine. Then I toast the bread in a 375 º oven until crisp, about 15 minutes.

Gluten-Free Creamed Mushroom Soup with Toasted Herb Croutons

Yield: 4

My favorite Campbell's soup was hands-down the cream of mushroom. This is my easy, straightforward version. Tomato bisque was definitely a close second. (My gluten-free, dairy-free interpretation of tomato bisque is on page 87 of Cooking for Isaiah.)


8 tablespoons unsalted butter

1 onion, finely chopped

Two 10-ounce containers white mushrooms, thinly sliced

3 cups vegetable or chicken broth

1 ½ cups heavy cream

Salt and pepper

3 tablespoons chopped fresh herbs (such as parsley, rosemary and thyme)

4 cups gluten-free bread, cut into cubes, such as Udi?s


  1. In a medium saucepan, melt 2 tablespoons butter over medium heat. Add the onion and cook until softened, about 5 minutes; transfer to a plate. In the same saucepan, melt 2 tablespoons butter and add the mushrooms. Cook until softened and the liquid has evaporated, about 15 minutes. Return the onion to the pan and stir in the broth; bring to a boil. Lower the heat and simmer for 15 minutes. Add the cream, 1 ½ teaspoons salt and ½ teaspoon pepper; cook until heated through, but do not boil.
  2. Transfer half of the mixture to a blender and puree. Return the mixture to the pan and keep warm.
  3. Meanwhile, preheat the oven to 375 °. In a microwavable bowl, melt the remaining 4 tablespoons butter. Stir in the herbs. Spread the bread cubes evenly on a baking sheet, drizzle with the butter mixture and season with salt and pepper; toss to coat. Toast in the oven, stirring occasionally, until crisp and golden, about 15 minutes. To serve, top the soup with the croutons.


  1. Oh my lord!!!! This was amazing! I LOVE cream of mushroom soup, it’s one of my favorites to order when I go out to eat, and now I can’t. I also grew up on Campbell’s and I used to eat it with about half a sleeve of crackers crushed up in it. Yum. Your soup was so good that I’m literally having a fit b/c there’s none left and I can’t make anymore right now. I had guests over and they, too loved it. The only change I made was using 2 cups of broth with 1/2 cup dry sherry and 1/2 white wine. Delicious! Thank you so much for posting this simple wonderful soup recipe!

  2. Looks like a great recipe. Could make it “Paleo” or “Primal” to fit my dietary style with a substitute for the croutons. Maybe roasted leeks!

  3. Do the croutons hold up in the soup? Every time I’ve tried using bread with liquid, the bread just disolves.

  4. Also being Dairy-Free, what would I use for the ‘heavy cream’? Would coconut creamer work, or maybe mimicreme? (cashew cream)

  5. I cook Dairy-Free, what could I use for the ‘heavy cream’?
    I really really want to make this for Thanksgiving!! ^^
    Please advice.

  6. How well does the soup store if you were to make it for the purpose of future recipes? Can it be freezed or how long is it good in the fridge?

  7. Yes would love to know what to substitute for the cream we also have a dairy allergy at our house.

  8. me too! I would guess a can of coconut milk but it could change the taste…….

  9. What’s the point of gluten free soup if you’re going to put crutons on top?
