A sweet roasted garlic and tangy sour cream sauce makes this made-for-company beef a winner.

1. Preheat oven to 325°F. Rub beef with cut sides of garlic halves. Sprinkle with salt and pepper. Place beef on a rack in a roasting pan.

2. In a small bowl, combine oil and minced garlic. Place whole garlic bulb in a small baking dish. Place beef and garlic bulb in oven. Roast for 50 minutes.

3. Brush beef with garlic-oil mixture. Continue roasting beef until an instant-read meat thermometer inserted into the center of beef reaches 160°F. for medium, about 20 minutes longer. Remove beef and garlic bulb from oven. Let stand for 10 minutes.

4. Slice top off garlic bulb. Using the tip of a knife, scoop out roasted garlic. To prepare sauce, in a small bowl, combine roasted garlic, sour cream, and milk. Mix well.

5. Cut beef into slices; arrange on a serving plate. Serve sauce on the side. Serve immediately.
