Leftover Steak Soup

If you using already cooked steak, cut into 1-inch cubes and set aside. In a heavy bottom pot over medium heat, add butter and olive oil. If using fresh steak, in a heavy bottom pot over medium high heat, add butter and olive oil. Cut the fresh steak into 1-inch cubes and season with salt. Sear all sides and then remove from the pot. Work in batches so you do not overcrowd the pot. Set cooked steak aside.

In the same pot over medium heat, add diced onion. Cook until onion is browned and softened. Now add garlic, herbs, and mushrooms. Continue to cook until mushrooms are browned and soft.

Add beef broth and xanthan gum. Bring soup to a boil and cook for a few minutes to let it thicken.

Add steak and cook for a few minutes to heat through. Ladle into bowls and serve.
