Roast Beef with Horseradish Cream

It's cold outside so I came across another warming comfort food recipe from delish.com. 
A juicy seasoned sirloin tip roast is the centerpiece of this delicious meal. With a side of roasted potatoes, it's sure to be a family favorite. Serve for dinner, or for a special occasion to feed a group.

Ingredients

    * 4 clove(s) garlic
    * 2 sprig(s) fresh rosemary
    * 1 teaspoon(s) olive oil
    * 1 tablespoon(s) olive oil
    * Sea Salt
    * Pepper
    * 1 1/2 pound(s) Yukon gold potatoes, cut in half (or quarters if large)
    * 1 whole(s) (2- to 2 1/2-pound) tri-tip (sirloin tip) roast, well-trimmed
    * 1/4 cup(s) heavy or whipping cream
    * 2 tablespoon(s) prepared horseradish
    * 1/2 teaspoon(s) Dijon mustard
    * 1/2 teaspoon(s) white wine vinegar

Directions

   1. Preheat oven to 475 degrees F. With side of knife, gently smash 3 cloves garlic; discard peel. Into small bowl, crush remaining clove garlic with press. Cut 1 rosemary sprig into 1-inch pieces; set aside. Remove leaves from other sprig; discard stem. Finely chop leaves and add to bowl with crushed garlic along with 1 teaspoon oil, 1/4 teaspoon salt, and 1/4 teaspoon freshly ground black pepper; set aside.
   2. In 18" by 12" jelly-roll pan, combine potatoes, remaining 1 tablespoon oil, smashed garlic, snipped rosemary, 1/4 teaspoon salt, and 1/4 teaspoon freshly ground black pepper until well mixed. Spread in even layer, making space in center of pan for beef. Place beef in center of pan, fat side down; rub with reserved garlic-rosemary mixture.
   3. Roast 20 minutes or until beef browns. Reset oven control to 350 degrees F. Roast 8 to 10 minutes or until temperature on meat thermometer, inserted into thickest part of beef, reaches 130 degrees F; transfer to cutting board. Cover loosely; let stand 10 minutes. Transfer potatoes to platter.
   4. Meanwhile, whisk cream, horseradish, mustard, vinegar, 1/8 teaspoon salt, and 1/8 teaspoon freshly ground black pepper until well blended. Slice meat thinly; serve with potatoes and horseradish cream.
