Keto Cream of Mushroom Soup – Throw out the can of Campbell’s and try our keto cream of mushroom soup instead. Ours is made with fresh mushrooms and thickened with cream. Eat the soup as-is, use it in casseroles, or top grilled chicken or steak.
WHAT YOU NEED TO MAKE THIS RECIPE
- Butter: Saute the onions in butter and add richness.
- Onion: I use yellow onion to sweeten the soup.
- Garlic: I suggest using four cloves, but don’t let my recipe tell you how much garlic to use – measure with your heart.
- Mushrooms: Feel free to use what you have on hand. I often use white or baby Bella mushrooms.
- Spices: Season the dish with dried thyme, kosher salt, and black pepper.
- Xanthan Gum: Use Xanthan to thicken the cream of mushroom soup and give it the perfect texture.
- Beef Broth: Use beef broth as the base for the soup.
- Sherry: I like to add a little sherry cooking wine to brighten the flavor of the beef broth.
- Heavy Cream: Give the soup a creamy consistency by stirring in heavy cream at the very end. You can also use half and half, but it might be too thin. For a non-dairy alternative, use coconut cream or full-fat coconut milk.

Uncover and remove the soup from heat; stir in the heavy cream to finish.
COOKING TIPS
- I prefer thick and creamy cream of mushroom soup. However, if you don’t like the chunkiness of the mushrooms, use an immersion blender to smooth them out.
