Preheat your oven to 275 degrees F.
Chop all the ingredients and layer in your Dutch oven. I added mine in this order:
Potatoes, beef, carrots, barley, onions, celery, tomatoes, pumpkin puree, herbs and seasonings. Then pour the broth and Worcestershire over all.
Cover the Dutch oven tightly with foil.
Place the lid on top of the foil covering.
Roast in the oven for 7 hours.
Stir, check the meat for done-ness and adjust the seasonings and amount of broth.
Serve in bowls, and garnish with fresh thyme and/or rosemary if desired.
