- Preheat oven to 325º. Set one oven rack in middle position and another in bottom position.
- Rinse corned beef several times under running cold water. (No need to dry)
- Place corned beef fat side up in large roasting pan (you'll trim fat aft meat is cooked). Pour about 1/8 inch water around meat. Sprinkle contents of seasoning packet into water around corned beef. Cover pan tightly with heavy-duty aluminum foil and roast on middle rack for 3 hours.
- Meanwhile, in small bowl, mix together melted butter, horseradish, salt and pepper.
- Place carrots, potatoes, and cabbage side by side on rimmed baking sheet (do not line pan with foil; potatoes will stick). Drizzle horseradish butter mixture over veggies and toss with spatula to coat all evenly, keeping vegetables separate. Turn potatoes so they are cut side down (they'll get crispier that way).
- After corned beef has roasted for 1 1/2 hours, place pan of veggies on bottom rack of oven. Roast veggies and continue cooking corned beef or 1 hour and 30 minutes more, util both meat and veggies are tender. Check occasionally to be sure they are browning evenly. (Cabbage will brown first, so give a toss when bottom pieces look golden. Potatoes and carrots may need to be turned but only if nicely browned on bottom for time is up.)
- Transfer corned beef to cutting board and let sit until cool enough to handle, about 5 minutes. Cut off layer of fat on top and discard. Slice meat again gran into 1/4 inch slices. Arrange on platter with roasted beatable and sprinkle with parsley. Serve with Horseradish Cream Sauce. (6-8 servings)
