Preheat oven to 325ºF
Heat oil in large dutch oven over medium/high heat. Generously salt roast then place in preheated dutch oven. Sear 3-4 minutes on each side. Remove roast and set aside.
Reduce heat to medium and add onions. Saute for 2 minutes.
Add wine and deglaze pan, scraping all the bits off the bottom and simmering the wine for 1 minute.
Add broth, garlic, thyme, rosemary, bay leaf, Worcestershire sauce, salt and pepper. Return roast to dutch oven. Cover and bake at 325ºF for 1.5 hours.
Add carrots, potatoes and mushrooms to dutch oven. Cover and bake 1.5 hours.
Check tenderness. If extra tender pot roast is preferred, cook 30-45 minutes more.
