Understanding Beef Tenderloin
The beef tenderloin, also known as filet mignon, is the most tender cut of beef due to its lack of connective tissues. It's located in the short loin and is renowned for its melt-in-your-mouth texture. However, it can be quite pricey, so it's essential to cook it right to enjoy its full potential.
Ingredients for a Perfect Beef Tenderloin Roast
- 1 whole beef tenderloin (about 3-4 lbs or 1.3-1.8 kg), trimmed
- 2 tbsp olive oil
- 4 cloves garlic, minced
- 2 tbsp fresh rosemary, finely chopped
- 2 tbsp fresh thyme leaves
- 1 tbsp Dijon mustard
- Salt and freshly ground black pepper, to taste
- 2 tbsp unsalted butter, at room temperature
Preparation: Seasoning and Tying the Roast
Preheat your oven to 450°F (230°C). Pat the beef tenderloin dry with paper towels to remove any excess moisture. This step is crucial for achieving a perfect sear.

In a small bowl, mix together olive oil, garlic, rosemary, thyme, Dijon mustard, salt, and black pepper. Rub this mixture evenly over the entire tenderloin, coating it completely.
Tie the roast with kitchen twine at 1-inch intervals to help it maintain its shape during cooking. This step also ensures even cooking.
Searing the Beef Tenderloin
Heat a large oven-safe skillet over high heat until it's smoking hot. Add the beef tenderloin and sear on all sides until browned, about 2-3 minutes per side. This step helps to develop a delicious crust and locks in the juices.

Roasting the Beef Tenderloin
Transfer the skillet to the preheated oven and roast the beef tenderloin until it reaches your desired level of doneness. Use a meat thermometer inserted into the thickest part of the roast to check the temperature. Here's a guide to help you:
| Desired Doneness | Internal Temperature |
|---|---|
| Rare | 125°F (52°C) |
| Medium-Rare | 135°F (57°C) |
| Medium | 145°F (63°C) |
| Well-Done | 160°F (71°C) |
Once the beef tenderloin has reached your desired temperature, remove it from the oven and transfer it to a cutting board. Let it rest for 15-20 minutes before slicing. This step allows the juices to redistribute throughout the meat.
Finishing Touches
While the beef is resting, mix the softened butter with 1 tbsp of the garlic and herb mixture used earlier. Once the beef has rested, slice it into 1-inch thick slices and top each slice with a small dollop of the garlic herb butter.
Serve your Beef Tenderloin Roast with your favorite sides, such as roasted vegetables, mashed potatoes, or a crisp salad. Enjoy your culinary masterpiece!
