Time 1h40m

Number Of Ingredients 10

2-1/4 cups water
1-1/2 cups ketchup
3 envelopes (.7 ounce each) italian salad dressing mix
1 tablespoon prepared mustard
3/4 teaspoon worcestershire sauce
1 beef tenderloin roast (3 to 4 pounds)
10 medium potatoes, peeled and quartered
1/2 cup butter, melted
1/2 teaspoon salt
1/4 teaspoon pepper

Steps:

1. In a small bowl, combine the first five ingredients. Pour half of the marinade into a large resealable plastic bag. Pierce tenderloin in several places; add to the bag and turn to coat. Seal and refrigerate for 8 hours or overnight. Cover and refrigerate remaining marinade for basting. Place potatoes in a large saucepan and cover with water. Bring to a boil; cook for 15-20 minutes or until crisp-tender. Drain; toss with butter, salt and pepper.
2. Drain and discard marinade. Place tenderloin on a rack in a shallow roasting pan. Arrange potatoes around meat. Bake, uncovered, at 375° for 60-75 minutes or until beef reaches desired doneness (for medium-rare, a meat thermometer should read 145°; medium, 160°; well-done, 170°), basting occasionally with reserved marinade. Let stand for 10 minutes before slicing; serve with pan juices and potatoes.
