Ingredients for Oven Roast Beef Tenderloin with Horseradish-Mustard Sauce
Here’s what you’ll need to make this delicious dish:
- Beef Tenderloin: A 2-3 pound cut will serve about 6 people; look for one with good marbling for extra flavor.
- Salt and Pepper: Essential for seasoning; kosher salt and freshly cracked black pepper work best.
- Olive Oil: Use extra-virgin olive oil for roasting, which adds flavor and helps achieve a beautiful crust.

- Dijon Mustard: Adds depth and tanginess; opt for whole grain if you like some texture in your sauce.
- Garlic Cloves: Minced garlic enhances the overall taste; about three cloves should do nicely.
For the Sauce:
- Sour Cream: Adds creaminess to your sauce; use full-fat for the richest flavor.

How to Make Oven Roast Beef Tenderloin with Horseradish-Mustard Sauce
Follow these simple steps to prepare this delicious dish:
Step 1: Preheat Your Oven
Preheat your oven to 425°F (220°C). This high temperature will help create that coveted crust on your beef tenderloin while keeping it juicy inside.
Step 2: Season Your Tenderloin
Pat your beef tenderloin dry with paper towels. Generously season it with salt and pepper on all sides. This step is crucial because it enhances flavor throughout the meat.
Step 3: Sear It Up
In a large oven-safe skillet over medium-high heat, add olive oil. Once hot, place the seasoned tenderloin in the skillet and sear each side until browned (about 3-4 minutes per side). This locks in those glorious juices.
Step 4: Mix That Sauce
While your beef is searing, combine grated horseradish, Dijon mustard, minced garlic, sour cream, and finely chopped chives in a bowl. Mix until well combined—this sauce will elevate your roast to another level.
Step 5: Roast Away
Once seared, transfer your skillet to the preheated oven. Roast for about 20-25 minutes or until an instant-read thermometer registers at least 130°F (54°C) for medium-rare doneness.
Step 6: Rest Before Serving
After removing from the oven, let your tenderloin rest for at least ten minutes before slicing. This allows juices to redistribute within the meat. Slice against the grain and serve drizzled with that heavenly horseradish-mustard sauce.
Transfer to plates and drizzle with sauce for the perfect finishing touch. Enjoy this delightful dish surrounded by loved ones—it’s not just food; it’s how memories are made!
