HOW TO MAKE STEAK SOUP

To get started with the soup, we first must have leftover steak or some steak hanging out in the fridge.  If you have steak already cooked, cut it into 1 inch cubes and move on to the next step.  For fresh steak, cut it into 1 inch cubes and sear it on all sides in a hot dutch oven or heavy bottom pot.  I did mine in batches.

After all of the steak has been browned, remove it from the pot and set it aside.  Then we add in the diced onion and let it caramelize.  Now it is time for the minced garlic, dried herbs, and the sliced mushrooms.

We want to get them softened and browned so they look like this:

Then we add in the beef broth and the soup is almost finished!  After the broth, I like to add in a thickener.  My preference is Xanthan gum because it only requires a teaspoon and it is low carb friendly.  You could also make a slurry.  After I add the xanthin gum, I bring the soup to a boil so it will start to thicken.

Now it’s time for the steak!  Tun off the heat and add in the steak, then ladle into bowls and serve.

      Cauliflower rice, diced eggplant, zucchini, or you could just add extra onion.
