Roast Beef Tenderloin with Horseradish Sauce 
Ingredients:
For the Beef Tenderloin:
2-3 lb beef tenderloin roast 
2 tbsp olive oil 
2 tsp garlic powder 
2 tsp fresh rosemary (chopped) 
Salt & pepper to taste 
For the Horseradish Sauce:
1/2 cup sour cream 
2 tbsp prepared horseradish (more for a spicier kick) 
1 tbsp Dijon mustard 
1 tsp lemon juice 
Salt & pepper to taste
Let’s Make It Happen:
Prepare the Tenderloin:
Preheat your oven to 450°F (232°C). Pat the beef tenderloin dry and season it generously with salt, pepper, garlic powder, and fresh rosemary. Drizzle olive oil over the roast and rub it in to coat evenly.
Roast the Beef:
Place the tenderloin on a roasting rack in a shallow pan. Roast in the preheated oven for 25–35 minutes, or until the internal temperature reaches 125°F for rare, 135°F for medium-rare, or 145°F for medium.
Rest the Beef:
Remove the beef from the oven and let it rest, covered with foil, for 10-15 minutes. This helps retain the juices for a tender, flavorful roast.
Make the Horseradish Sauce:
While the beef is resting, whisk together sour cream, horseradish, Dijon mustard, lemon juice, salt, and pepper in a bowl. Adjust the horseradish amount to your desired spice level.
Serve:
Slice the roast beef against the grain and serve with a dollop of horseradish sauce on the side. Pair with roasted vegetables or mashed potatoes for the perfect meal.
Tips for Extra Magic:
For a more intense flavor, rub the beef with minced garlic and fresh herbs a few hours before roasting.
Add a little Worcestershire sauce or beef broth to the horseradish sauce for depth.
Serve with a rich red wine reduction or a classic au jus for extra indulgence. 
Enjoy:
A tender, juicy beef tenderloin paired with the perfect zingy horseradish sauce—this dish is fit for any special occasion!
