1 beef Tenderloin Roast Center-Cut (2 to 3 pounds)
1 pound yellow onions, peeled, cut into wedges
2-1/2 pounds Brussels sprouts, trimmed
1 tablespoon olive oil
1-1/4 teaspoons salt, divided
2 tablespoons chopped fresh thyme leaves
1 tablespoon pepper
1/3 cup balsamic vinegar
3 tablespoons finely chopped shallots
1 can (16 ounces) whole berry cranberry sauce
Heat oven to 425°F. Combine onions, Brussels sprouts, oil and 1 teaspoon salt on metal baking pan; toss to coat. Set aside.
Combine thyme and pepper in small bowl. Reserve 1 teaspoon thyme mixture for sauce; set aside. Press remaining thyme mixture evenly onto all surfaces of beef Tenderloin Roast.
Place roast on rack in shallow roasting pan. Insert ovenproof-meat thermometer so tip is centered in thickest part of beef. Do not add water or cover. Place prepared vegetables in oven with roast. Roast beef in 425 F oven 35 to 45 minutes for medium rare; 45 to 50 minutes for medium doneness. Roast vegetables 45 to 50 minutes or until tender and lightly browned
Meanwhile, prepare sauce. Combine vinegar and shallots in small saucepan; bring to a boil. Reduce heat; simmer 3 minutes. Stir in cranberry sauce; bring to a boil. Reduce heat; simmer 6 minutes to blend flavors, stirring occasionally. Remove from heat; stir in reserved 1 teaspoon thyme mixture and remaining 1/4 teaspoon salt. Keep warm.
Carve roast into slices; serve with vegetables and sauce.
