How to Make Roast Beef Tenderloin Reverse Sear: Step-by-Step Instructions

1. Prepare the Beef

Start by removing the beef tenderloin from the refrigerator about 30 minutes before cooking. This helps the meat come to room temperature and ensures even cooking. Pat the tenderloin dry with paper towels to remove any excess moisture, which will help with the searing process later.

2. Season the Beef

Rub the entire surface of the tenderloin with olive oil. Sprinkle a generous amount of kosher salt and freshly ground black pepper all over the meat. Add garlic powder, fresh rosemary, and thyme to the beef, massaging the herbs and spices into the surface to ensure an even coating. The seasoning will create a flavorful crust when seared.

3. Roast the Beef (Reverse Sear Method)

Preheat your oven to 275°F (135°C). Place the seasoned tenderloin on a roasting pan or sheet tray. Insert a meat thermometer into the thickest part of the meat to monitor the internal temperature. Roast the beef in the preheated oven for about 45 to 60 minutes, depending on the size of the tenderloin and your preferred level of doneness:

• Rare: 120°F (49°C)
• Medium-Rare: 125°F (52°C)
• Medium: 135°F (57°C)
• Medium-Well: 145°F (63°C)
• Well Done: 150°F (66°C)

Keep an eye on the thermometer, as the roast will continue to cook a bit after you remove it from the oven.

4. Sear the Beef

Once the beef reaches the desired internal temperature, it’s time for the reverse sear! Heat a large oven-safe skillet or cast iron pan over medium-high heat. Add a tablespoon of olive oil to the hot pan, allowing it to heat up. Add the beef tenderloin to the pan and sear it on all sides, turning with tongs to ensure the entire surface gets a golden-brown crust. This should take about 2-3 minutes per side. Add a couple of cloves of garlic and a few sprigs of fresh rosemary or thyme to the pan for extra flavor while basting the beef with melted butter.

5. Rest the Beef

Once the beef is seared to perfection, remove it from the pan and transfer it to a cutting board. Let it rest for at least 10 minutes before slicing. This allows the juices to redistribute throughout the meat, ensuring it stays tender and juicy when cut.

How to Serve Roast Beef Tenderloin Reverse Sear

This beef tenderloin is a standout dish and can be served in a variety of ways:

• With Roasted Vegetables: Pair the tenderloin with roasted vegetables like potatoes, carrots, or Brussels sprouts for a complete meal.
• On a Charcuterie Board: Slice the tenderloin thinly and serve it as part of a charcuterie board with cheeses, crackers, and spreads.
• With a Side Salad: A fresh green salad with a tangy vinaigrette balances the richness of the beef.
• With Mashed Potatoes or Gravy: The creamy texture of mashed potatoes or a rich gravy complements the tender, flavorful beef perfectly.

Storing Roast Beef Tenderloin Reverse Sear

• Leftovers: Store any leftover beef in an airtight container in the refrigerator for up to 4 days.
• Reheating: To reheat, place the beef slices in a skillet over low heat with a little bit of broth or water to keep them moist. You can also gently reheat in the microwave in short intervals.

Tips and Tricks for Success

• Use a Meat Thermometer: A meat thermometer is the best way to ensure your roast reaches the perfect doneness without overcooking.
• Rest the Beef: Don’t skip the resting step! It ensures a juicy roast, and slicing too soon can cause the juices to run out.
• Try Different Herbs: If you don’t have rosemary or thyme, you can experiment with other fresh herbs like sage or oregano to add your own twist to the flavor.
• Searing Tip: Make sure the pan is hot enough before you add the beef. A well-heated pan will give you that delicious crust without overcooking the meat.

Roast Beef Tenderloin Reverse Sear FAQs

How can I ensure the beef is cooked perfectly?

Using a meat thermometer is the most reliable way to check for your preferred level of doneness. The beef should be removed from the oven when it’s 5°F below your target temperature, as it will continue to cook during the searing and resting steps.

Can I make this dish ahead of time?

Yes, you can prepare the beef in advance. Roast it as directed, then refrigerate it once it’s cooled. When you’re ready to serve, gently reheat the slices in a skillet with a little broth or water to keep them moist.

What should I do if I don’t have a cast iron skillet?

If you don’t have a cast iron skillet, you can use any heavy oven-safe skillet to sear the beef. Just make sure it’s large enough to hold the tenderloin without crowding.

Can I use a different cut of beef?

While beef tenderloin is ideal for this recipe due to its tenderness, you can use a different cut, like a ribeye or sirloin. Keep in mind that the cooking time may vary depending on the cut.
