Sprinkle roast with seasoned salt and lemon pepper to taste. Place onion and carrot in the bottom of a 5 or 6 quart crockery cooker. Lay the meat on top of the vegetables. Pour in the broth and Worcestershire sauce. Season with garlic, rosemary and thyme.
Cover and set dial to low-heat. Allow to gently simmer for 5 to 6 hours. Remove the cover and add the baby vegetables around the roast. Sprinkle with seasoned salt and continue to cook covered on low-heat for an additional 1 to 1 1/2 hours.
