Oven-baked Corned Beef Dinner
Preheat oven to 300° F. Place corned beef in a large, flat baking pan or covered roaster. Add water to a depth of 1/4 inch. Cover with a lid or foil and place in oven for 3 1/2 to 4 hours. The beef should be very tender when tested with a large fork.
When corned beef is done, transfer to an oven-proof plate, cover with aluminum foil and hold in a warm oven. Pour cooking liquid into a deep kettle and add 3 cups water; bring to a boil. Add potatoes and simmer 10 minutes. Add carrots and simmer until just tender. About 10 minutes before the vegetables are cooked, add cabbage wedges and cook until tender crisp.
Slice corned beef across the grain and serve on a platter surrounded by cabbage. Transfer the potatoes and carrots to a separate bowl and serve with horseradish.
