Ingredients for Success
Here’s everything you’ll need for this show-stopping beef tenderloin:
- 4 to 5 lb beef tenderloin, trimmed, cut into two pieces, and tied
- 1 tsp salt
- 1/2 tsp black pepper
- 2 tbsp olive oil
- 4 tbsp salted butter, softened
- 2 tsp garlic, minced
- 1 tsp prepared horseradish or Dijon mustard
- 1 tsp fresh rosemary or thyme, finely minced
These ingredients work together to build a rich, aromatic crust that locks in juices and flavor. Don’t skip the horseradish or Dijon — it adds just enough zing to make the meat sing.
Step-by-Step Cooking Instructions
1. Prepare the Tenderloin
- Tie the beef tenderloin with butcher’s twine in 1–2 inch intervals to maintain a uniform shape and ensure even cooking.
- Season all sides generously with salt and pepper.
- Let the tenderloin rest at room temperature for 2 hours before cooking. This allows for more even roasting.
2. Sear for Flavor
- Preheat your oven to 425°F (220°C).
- Heat olive oil in a large cast-iron skillet over medium-high heat.
- Sear the tenderloin for 3-5 minutes per side, until all sides have a deep golden-brown crust.
3. Make the Herb Butter Crust
- In a small bowl, mix the softened butter, minced garlic, horseradish or Dijon, and rosemary or thyme.
- Spread the mixture evenly over the seared beef. This will create a savory, fragrant crust as it roasts.
4. Roast to Perfection
- Insert a probe thermometer into the thickest part of the beef.
- Transfer the skillet to the oven (or place the beef in a baking dish).
- Roast for 20-25 minutes, or until the internal temperature reaches:
- 125°F for medium-rare
- 135°F for medium
- 145°F for medium-well
5. Rest and Slice
- Remove the tenderloin from the oven and let it rest, uncovered, on a cutting board for 15–20 minutes.
- Slice into 1-inch thick rounds and serve warm.
Kitchen Equipment Needed
To execute this dish like a pro, gather the following:
- Cast-iron skillet or heavy oven-safe pan
- Probe or instant-read meat thermometer
- Butcher’s twine
- Sharp chef’s knife
- Cutting board
- Small mixing bowl
- Tongs
Tips for Best Results
- Let it rest: Skipping the rest period after roasting can result in a pool of lost juices on your cutting board. Give it time.
- Use a thermometer: Don’t guess doneness. A probe thermometer ensures you don’t overcook such an expensive cut.
- Choose fresh herbs: Rosemary and thyme add depth. Fresh is best, but dried can be used in a pinch (use only 1/3 the amount).
- Trim smart: Ask your butcher to trim and tie the tenderloin for you to save prep time.
Recipe Swaps and Variations
- Garlic Herb Compound Butter: Add lemon zest or cracked pepper for a twist on the butter rub.
- Spice Crust: Mix in smoked paprika or cumin for a deeper, smoky flavor profile.
- Bacon-Wrapped Tenderloin: For extra indulgence, wrap the tenderloin in thin strips of bacon before roasting.
- Wine Reduction Sauce: While resting, use the pan drippings to make a red wine reduction — simply deglaze with wine and simmer with a bit of beef broth.
What to Serve With Roast Beef Tenderloin
This dish pairs beautifully with elegant yet simple sides. Here are some favorites:
- Garlic mashed potatoes
- Roasted Brussels sprouts with balsamic glaze
- Creamed spinach
- Buttered green beans with slivered almonds
- Cauliflower gratin
Drink Pairings:
- Red wine: A bold Cabernet Sauvignon, Merlot, or Bordeaux complements the richness of the beef.
- Cocktails: An Old Fashioned or Manhattan makes for a classy pairing.
- Non-alcoholic: Sparkling pomegranate juice or a rosemary citrus mocktail brings balance and sophistication.
Storing and Reheating Leftovers
Storage:
- Wrap leftovers tightly in foil or place in an airtight container.

Freezing:
- You can freeze cooked tenderloin in slices. Wrap individually in plastic and store in a freezer bag for up to 2 months.

Frequently Asked Questions
Can I prep this beef tenderloin ahead of time?
Yes! You can season and tie the tenderloin up to 24 hours in advance. Keep it wrapped in the fridge and let it come to room temperature before cooking.
Can I use a different cut of beef?
If tenderloin isn’t available, a center-cut sirloin roast or ribeye roast can be used, though the cooking time and texture will differ.
Is horseradish mandatory?
No, but it adds a subtle sharpness that contrasts the richness of the beef. Dijon mustard is a great alternative.
What if I don’t have a cast-iron skillet?
Any oven-safe skillet will do. Alternatively, sear the beef in a regular pan and transfer it to a roasting pan to finish in the oven.
