  • 2 tbsp butter
  • 2 tbsp olive oil
  • 1/2 cup onion diced
  • 2 cloves garlic minced
  • 2 lbs mushrooms sliced, I use a mix of white button and crimini
  • 2 tsp fresh thyme chopped & divided
  • 5 cups low sodium chicken broth use vegetable broth to make it vegetarian
  • 1/2 tsp Xanthan gum https://amzn.to/2J58gyX
  • 1/2 tsp freshly cracked pepper
  • salt to taste
  • 2 oz cream cheese softened, omit for dairy free version
  • 1 cup heavy cream omit for dairy free and swap with canned coconut milk
  • Freshly cracked pepper & fresh thyme to garnish


  • Heat butter and oil in a large pot over medium-high heat until melted.
  • Sauté onion for 2 to 3 minutes until softened. Cook garlic until fragrant, about 1 minute.
  • Add mushrooms and cook on high for 5 minutes.
  • Add sat, pepper, & 2 tsp thyme .
  • Add the broth, and xanthan gum.
  • Whisk until the xanthan gum is fully incorporated and bring to a boil. Reduce heat to low-medium heat.
  • Cover and allow to simmer for 10-15 minutes, while occasionally stirring.
  • Whisk in the softened cream cheese.
  • Add in the heavy cream & turn the flame off. . Adjust salt and pepper to your taste.
  • I like to serve it with bits of bacon , cracked pepper, & extra fresh thyme.
  • I often make it into a meal by adding some rotisserie chicken.
  • This soup will stay in the fridge for up to a week. Great do ahead if you're planning on making some green bean casserole for Thanksgiving, perhaps.
  • I have never had leftovers so I have never frozen it.
