Understanding Beef Tenderloin

Beef tenderloin is one of the most tender and luxurious cuts of beef, often referred to as "filet mignon" when sliced into steaks. It is a long, cylindrical muscle that runs along the spine of the cow and does very little work, resulting in its tender texture. Knowing how to cook beef tenderloin to perfection is key to enjoying its delicate flavor and texture.

Choosing the Right Beef Tenderloin

Before diving into cooking times, selecting a quality beef tenderloin is crucial. Look for a piece that has a bright red color with a good amount of marbling—those fine streaks of fat that run through the meat. The marbling will melt during cooking, enhancing the meat's flavor and juiciness.

Preparation Tips

To ensure even cooking, it's vital to start with a room-temperature tenderloin. Remove the beef from the refrigerator at least 30 minutes before cooking. Season it generously with salt and pepper, and consider adding garlic, rosemary, or thyme for extra flavor. Some chefs recommend tying the tenderloin with kitchen twine to maintain an even shape, ensuring uniform cooking.

Cooking Methods and Times

Oven Roasting

Oven roasting is a popular method for cooking beef tenderloin, especially for larger gatherings.

1. Preheat your oven: Set the oven to 425°F (220°C).

2. Sear the tenderloin: Heat a heavy skillet over medium-high heat and sear the tenderloin on all sides until browned, about 3-4 minutes per side.

3. Roast in the oven: Transfer the seared tenderloin to a roasting pan and place it in the oven.

- For medium-rare (130°F to 135°F or 54°C to 57°C): Roast for approximately 20-25 minutes.

- For medium (140°F to 145°F or 60°C to 63°C): Roast for about 25-30 minutes.

- For medium-well (150°F to 155°F or 65°C to 68°C): Roast for around 30-35 minutes.

4. Rest the meat: Once the desired internal temperature is reached, remove the tenderloin from the oven and let it rest for at least 15 minutes before slicing. This allows the juices to redistribute, ensuring a moist and flavorful result.

Grilling

Grilling can impart a smoky flavor that complements the tenderloin's natural richness.

1. Preheat the grill: Heat your grill to high heat, around 450°F to 500°F (230°C to 260°C).

2. Sear the tenderloin: Sear the beef on all sides for about 2-3 minutes per side to develop a nice crust.

3. Indirect grilling: Move the tenderloin to a cooler part of the grill to finish cooking indirectly.

- For medium-rare: Grill for an additional 20-25 minutes.

- For medium: Grill for approximately 25-30 minutes.

- For medium-well: Grill for about 30-35 minutes.

4. Rest the meat: Remove the tenderloin from the grill and let it rest for 15 minutes before serving.

Pan-Seared and Oven-Finished

Combining pan-searing with oven finishing offers the best of both worlds: a beautifully caramelized crust and an evenly cooked interior.

1. Preheat the oven: Set the oven to 400°F (200°C).

2. Sear the tenderloin: Heat a large, oven-safe skillet over medium-high heat. Add some oil and sear the tenderloin on all sides for about 3-4 minutes per side.

3. Finish in the oven: Transfer the skillet to the preheated oven.

- For medium-rare: Bake for about 15-20 minutes.

- For medium: Bake for around 20-25 minutes.

- For medium-well: Bake for approximately 25-30 minutes.

4. Rest the meat: Allow the tenderloin to rest for 15 minutes before slicing and serving.

Using a Meat Thermometer

Regardless of the cooking method, using a meat thermometer is the most reliable way to ensure your beef tenderloin reaches the desired level of doneness. Insert the thermometer into the thickest part of the tenderloin, avoiding any bones or fat pockets. The internal temperature guide is as follows:

- Rare: 120°F to 125°F (49°C to 51°C)

- Medium-Rare: 130°F to 135°F (54°C to 57°C)

- Medium: 140°F to 145°F (60°C to 63°C)

- Medium-Well: 150°F to 155°F (65°C to 68°C)

Resting the Beef Tenderloin

Resting is a crucial step often overlooked. Allowing the beef tenderloin to rest for at least 15 minutes after cooking helps the juices redistribute throughout the meat, resulting in a more flavorful and tender bite. During this resting period, the internal temperature of the meat will continue to rise by about 5°F (3°C), so take this into account when aiming for your desired doneness.

Finishing Touches

To elevate your beef tenderloin, consider adding a finishing touch such as a compound butter, a drizzle of high-quality olive oil, or a sprinkle of flaky sea salt. Serving with a rich sauce like a red wine reduction or a creamy béarnaise can also enhance the overall dining experience.

Rarely Known Tips

For an extra layer of flavor, dry-brine the beef tenderloin by salting it and letting it sit uncovered in the refrigerator for up to 24 hours before cooking. This process not only seasons the meat deeply but also helps to dry out the surface, leading to a better sear.

Consider the thickness of the tenderloin when planning cooking times. A thinner tenderloin will require less time, while a thicker one will need more. Always adjust accordingly and rely on your meat thermometer for the best results.

Cooking beef tenderloin to perfection involves a blend of choosing the right cut, preparing it properly, selecting the appropriate cooking method, and paying close attention to internal temperatures. With these tips and techniques, you're well on your way to mastering this elegant and flavorful cut of beef.
