Ingredients for Oven Roast Beef Tenderloin

Here’s what you’ll need to create this magnificent Oven Roast Beef Tenderloin. I’ve found that using quality ingredients makes all the difference for a truly memorable dish.

• 2 to 3 pounds beef tenderloin – I always look for a center-cut piece for even cooking.

• 1 tablespoon salt – I prefer kosher or sea salt for better flavor.
• 1 tablespoon freshly ground black pepper – fresh pepper adds a wonderful aroma and bite.
• 2 tablespoons fresh rosemary (chopped) or 1 tablespoon dried – this is essential for a fragrant beef tenderloin roast with herbs.
• 2 tablespoons Dijon mustard – for the sauce, it adds a tangy kick.
• 2 tablespoons prepared horseradish – gives the sauce its signature zing.
• ½ cup sour cream – to create a creamy, balanced sauce.
• 1 tablespoon lemon juice – brightens up the horseradish-mustard sauce.
• Fresh herbs for garnish (optional) – a little extra rosemary or parsley makes for a beautiful presentation.

How to Make Oven Roast Beef Tenderloin

Making a show-stopping Oven Roast Beef Tenderloin is simpler than you might think! Follow these steps, and you’ll be serving up a perfectly tender and flavorful roast that will impress everyone at your table. I’ll walk you through each stage to ensure your success.

1. Step 1: First, preheat your oven to a robust 425°F (220°C). This high heat is crucial for developing a beautiful crust on the beef while keeping the inside wonderfully juicy.
2. Step 2: Remove the beef tenderloin from the refrigerator about 30 minutes before you plan to cook it. This allows the meat to come closer to room temperature, which helps immensely with even cooking. Pat the beef thoroughly dry with paper towels; this step is vital for achieving a good sear.
3. Step 3: Rub the entire surface of the beef tenderloin generously with olive oil, then season it liberally with salt and freshly ground black pepper. After that, sprinkle the chopped rosemary evenly over the beef, pressing it gently so it adheres. This creates a fragrant crust that infuses flavor throughout the roast.
4. Step 4: Heat a large, oven-safe skillet over medium-high heat until it’s smoking slightly. Carefully sear the beef tenderloin on all sides for about 2-3 minutes per side. You’re looking for a deep, golden-brown crust, which locks in the juices and adds incredible depth of flavor to your Oven Roast Beef Tenderloin.
5. Step 5: Once seared, transfer the beef tenderloin directly to a roasting pan or a baking sheet. If you used an oven-safe skillet, you can simply move it straight into the oven. This method is excellent for cooking beef tenderloin whole in oven, ensuring it cooks evenly.
6. Step 6: Roast the beef in your preheated oven for about 25-30 minutes. I always recommend using a meat thermometer to monitor the internal temperature. For a medium-rare doneness, aim for 110-120°F (43-49°C) for rare, 125-130°F (52-54°C) for medium-rare, and 135-140°F (57-60°C) for medium. Remember, the beef will continue to cook slightly as it rests.
7. Step 7: While your Oven Roast Beef Tenderloin is cooking, prepare the decadent horseradish-mustard sauce. In a small bowl, whisk together the Dijon mustard, prepared horseradish, sour cream, and fresh lemon juice until smooth. Taste and adjust the seasoning with a pinch more salt and pepper if needed.
8. Step 8: Once the beef reaches your desired internal temperature, remove it from the oven. This is a critical moment for a tender result! Transfer the roast to a cutting board and let it rest, uncovered, for 10-15 minutes. This resting period allows the juices to redistribute throughout the meat, preventing them from escaping when you slice it.
9. Step 9: After resting, slice the beef tenderloin into beautiful 1-inch thick medallions. Arrange these savory slices on a serving platter.
10. Step 10: Serve your perfectly cooked Oven Roast Beef Tenderloin with a generous spoonful of the zesty horseradish-mustard sauce over each slice. For an extra touch of elegance, garnish with fresh herbs like a sprig of rosemary or parsley. Enjoy this magnificent dish!

How to Store and Reheat Oven Roast Beef Tenderloin

Properly storing and reheating your leftover Oven Roast Beef Tenderloin is key to enjoying its deliciousness for days to come. I always make sure to handle leftovers carefully to maintain their quality and flavor.

First, allow any remaining beef tenderloin to cool completely at room temperature, but no longer than two hours. Once cooled, transfer the slices or whole roast into an airtight container. It will keep beautifully in the refrigerator for 3-4 days.

For longer storage, you can freeze individual slices or larger portions. Wrap them tightly in plastic wrap, then an additional layer of aluminum foil or place them in a freezer-safe bag. Your Oven Roast Beef Tenderloin can be stored in the freezer for up to 3 months.

When you’re ready to enjoy it again, thaw frozen beef overnight in the refrigerator. To reheat, I recommend using a low oven temperature, around 300°F (150°C), especially for larger pieces. This gentle reheating method ensures the meat stays tender and doesn’t dry out, following the best oven baked beef tenderloin cooking instructions for leftovers. You can also gently warm slices in a covered skillet on low heat with a splash of broth.

Frequently Asked Questions About Oven Roast Beef Tenderloin

What internal temperature should I aim for with Oven Roast Beef Tenderloin?

For a perfect medium-rare Oven Roast Beef Tenderloin, I always pull it from the oven when its internal temperature reaches 135°F (57°C). Remember, the temperature will rise another 5-10 degrees as it rests. For medium, aim for 140°F (60°C) before resting.

How long should I roast beef tenderloin per pound?

The roasting time can vary, but generally, you can estimate about 10-15 minutes per pound for a Oven Roast Beef Tenderloin cooked to medium-rare, after searing. This will depend on your oven and the thickness of the roast. Always use a meat thermometer to be precise rather than relying solely on time.

Can I use a different cut of beef for this recipe?

While this recipe is optimized for Oven Roast Beef Tenderloin, you could adapt it for other tender cuts like a strip loin or ribeye roast. However, cooking times and internal temperatures would need to be adjusted accordingly. For the best tender and luxurious result, I stick with tenderloin.

What if my Oven Roast Beef Tenderloin is cooking too fast or too slow?

If your Oven Roast Beef Tenderloin is cooking too fast, you might need to lower your oven temperature slightly or tent it loosely with foil. If it’s too slow, ensure your oven is accurately calibrated. The best defense against uneven cooking is always that reliable meat thermometer to monitor progress.

Variations of Oven Roast Beef Tenderloin You Can Try

While my classic Oven Roast Beef Tenderloin recipe is a winner, I love experimenting with different flavors to keep things exciting. These variations offer new ways to enjoy this magnificent cut of beef, proving how versatile an easy oven roasted beef tenderloin can be.

• Garlic Herb Crusted: For an intensely aromatic twist, finely mince 4-5 cloves of garlic and mix them with the rosemary, adding a touch of fresh thyme and oregano. Press this potent herb mixture all over the tenderloin before searing and roasting.
• Spicy Chili Rub: If you enjoy a little heat, create a rub with chili powder, cumin, smoked paprika, and a pinch of cayenne pepper. This gives your Oven Roast Beef Tenderloin a vibrant, smoky flavor profile that pairs wonderfully with the rich beef.
• Mushroom Duxelles Stuffed: For a truly gourmet experience, carefully butterfly the tenderloin, spread a savory mushroom duxelles (finely chopped mushrooms sautéed with shallots and herbs) inside, then roll and tie it before roasting. This adds incredible moisture and umami.
• Wine Reduction Sauce: Instead of the horseradish sauce, deglaze the pan drippings after searing with a cup of red wine, beef broth, and a sprig of rosemary. Reduce until slightly thickened for a rich, sophisticated accompaniment to your easy oven roasted beef tenderloin.
