Set temp to 400F & when the pan is hot, sear all sides of roast. Add 1" of water and reduce temp to
350F.
Add a dash of Worcestershire to the roast. Cover and cook for two hours.
During cooking time, periodically pour Worcestershire sauce over roast & add water as needed. After the first 1/2 hour, add the onions. After the 1st hour, add the rest of the veggies. The veggies only take about 30-40 minutes to become tender.
Roast is done when it suits you or in 2 hours or when meat thermometer reads 180F. When done, unplug pan, slice roast in the pan and let everyone enjoy. If desired add horseradish to your own plate. Good with warm bread/crusty rolls.
