To make the short stock, roughly chop the onions, celery and carrot. Heat a pot over medium-high heat and add the oil. Sauté the mirepoix until it starts to brown. Once browned, add the bones, followed by the stock.

*Note: I usually make this soup after I have made Prime Rib. I just freeze the bones and any leftover meat until I am ready to make the soup.

Next, add the seasonings and bring to a simmer. Let cook for at least 1 1/2 hours, to fully extract the flavors.

While the stock is cooking, you can prepare the mirepoix for the soup.

Once done the stock is done, strain it and remove any excess fat. Set aside while you start the soup.

To prepare the mirepoix, dice the celery, carrots and onions into medium dice. Try and cut all of the mirepoix roughly the same size.

The amount of mirepoix you will need will depend on how much stock you have and how thick you like your soup. If you like beef barley soup to be fairly thick, the pot of soup can be almost half full of mirepoix.

To gauge how much you will need, first see how much stock you have and then chop just over half of that amount in mirepoix (it will reduce in size a little once cooked). For about 8 cups of stock, use about 5 cups of mirepoix.

To prepare the beef, remove any excess fat and then dice into cubes about the same size as the mirepoix.

To start the soup, heat a large pot over medium-low heat. Add enough oil to lightly coat the surface of the pot and then add the mirepoix. Season with a bit of salt and pepper.

Sweat the mirepoix for about 15 minutes or until softened. Meanwhile, mince the garlic and set aside.

Once the vegetables have started to soften and become somewhat translucent, add the garlic and cook for another 30 seconds or so.

Add the beef to the mirepoix.

Next, add the stock to the soup pot and gently stir to combine. Add the bay leaf and the leaves from the sprigs of thyme.

Season with a bit of salt and pepper. Depending on how salty your stock and bones were, you may need to add a teaspoon or more of salt. Simply adjust the seasoning as you go.

Bring the soup to a gentle simmer. Let cook for about 30 to 40 minutes or until the beef starts to fall apart a bit and the vegetables are cooked through, but not mushy.

As the soup simmers, cook the barley. Add the barley to a medium pot along with the stock and seasoning. Bring to a boil and then turn down the heat. Cover with a tight fitting lid and let simmer for about 30 minutes.

Once done, remove from the heat and let rest for about 10 minutes. Remove the lid and let sit until the soup has finished cooking.

To finish the soup, add the cooked barley to the soup, stir and taste for seasoning. If you like, you can add a bit more fresh thyme. Adding it at this stage will keep it bright and makes for nice presentation.

To serve the soup, garnish with a teaspoon or so of horseradish and Dijon, if you like. Serve this hearty soup with some nice French bread or some garlic crostini, if desired.
