This creamy keto mushroom soup recipe is made with brown butter and sage for delicious rich flavor. Easy to make and with only 5 ingredients, it’s a perfect keto soup recipe for those chilly days.

This Keto Mushroom Soup Recipe was first published in December 2012. But it’s such a lovely and easy soup, I decided it needed a little update. I’ve even included a video to show you just how easy it is to make.

Making cream of mushroom soup is so easy, I honestly don’t know why anyone would use store-bought. It takes less than 20 minutes to make and it’s so much more flavorful.

Step away from the canned soup, people!And make my simple keto mushroom soup instead. It takes only 5 ingredients and is so much healthier, with a richer, fresher flavor. Let’s do a little comparison, shall we?

The typical canned mushroom soup contains some pretty scary ingredients. Most of them are made with things like soybean oil, wheat flour, and MSG. Even the so-called healthier, organic brands have additives like rice flour to thicken it.

Kettle and Fire does make a decent keto friendly soup in cartons. The ingredients aren’t scary (yay!), but it’s rather expensive. And it has quite a long ingredient list for what should be a simple soup.

My recipe, on the other hand, is thick, creamy, and contains 5 simple ingredients. It doesn’t cost a fortune to make and I guarantee you that the flavor is far superior to that of anything from a can or a carton.

1. Brown the butter: In a large pot, heat the butter over medium heat until it begins to brown and turns fragrant, 3 to 4 minutes. Add the sage and cook one minute more.

2. Sauté the mushrooms:Add the mushrooms and stir to coat, then sauté until the mushrooms are tender and lightly browned, 4 to 5 minutes.

4. Blend it up.Transfer the soup to a food processor or good blender and blend until smooth (you may need to work in batches). You can also use an immersion blender but it tends not to get it as smooth.

Don’t skip the browned butter, as it’s what makes this Keto Mushroom Soup recipe so special. Browned butter has a rich, nutty caramel flavor and it goes beautifully with mushrooms and herbs.

Store any leftovers in an air tight container in the fridge for up to a week, as long as your cream was fresh. Since milk fat separates when it freezes, I don’t suggest freezing leftovers. But you can freeze the soup minus the cream and then add the cream when you re-heat it.

If you want a chunkier soup, don’t purée completely or set aside a portion of the mushrooms and add them to the puréed mixture afterwards.

Dairy-Free Option: Use coconut milk for the heavy cream. If you can tolerate ghee, there is a browned butter ghee that would be great. Otherwise use butter-flavored coconut oil.

All varieties of mushrooms are naturally low in carbohydrates. So they make an excellent addition to keto recipes. They add flavor, but they also contain a number of vital nutrients and minerals such as Vitamin D.

Ingredient Mushroom Soup Recipe

Optional extra: Add ⅓ cup or 10 grams of dried porcini mushrooms. These really elevate the taste! They need to be soaked for 5 minutes in hot water and then washed well before you add them to the soup.

Like your soup extra rich? Use ½ cup heavy cream and / or add 4oz or 120 grams of cream cheese at the end. In this case, cook the soup an additional 10 minutes after adding the cream to reduce the liquid and intensify the taste.
