## Ingredients:

* **Beef Tenderloin:** 2-3 pounds, trimmed of excess silver skin and fat
* **Olive Oil:** 3 tablespoons, extra virgin
* **Fresh Herbs:**
* 2 tablespoons fresh rosemary, finely chopped
* 2 tablespoons fresh thyme, finely chopped
* 1 tablespoon fresh oregano, finely chopped
* 1 tablespoon fresh parsley, finely chopped
* **Spices:**
* 2 teaspoons garlic powder
* 2 teaspoons onion powder
* 1 teaspoon smoked paprika
* 1 teaspoon black pepper, freshly ground
* 1/2 teaspoon red pepper flakes (optional, for a touch of heat)
* 1 teaspoon kosher salt (or sea salt)
* **Garlic:** 4 cloves, minced
* **Dry Red Wine (Optional):** 1/2 cup, for deglazing the pan (Cabernet Sauvignon or Merlot work well)
* **Beef Broth (Optional):** 1 cup, for deglazing the pan
* **Butter (Optional):** 2 tablespoons, cold, cut into small pieces, for finishing the sauce

## Equipment:

* Roasting pan with a rack
* Kitchen twine
* Meat thermometer (instant-read recommended)
* Large skillet (cast iron preferred, but any heavy-bottomed skillet will work)
* Aluminum foil
* Small bowl
* Whisk (if making the pan sauce)

## Instructions:

### 1. Prepare the Beef Tenderloin:

* **Trimming:** This is a crucial step. Use a sharp knife to carefully remove any silver skin (a thin, tough membrane) from the tenderloin. This skin does not break down during cooking and can make the roast chewy. Also, trim off any large pieces of excess fat. A little fat is good for flavor, but too much will render and cause the roast to steam rather than sear. The goal is a nicely shaped, relatively uniform tenderloin.
* **Tying (Optional):** Tying the tenderloin ensures even cooking and a more attractive presentation. Use kitchen twine to tie the tenderloin at 2-inch intervals. This helps the tenderloin maintain a consistent thickness and prevents the thinner ends from overcooking. If your tenderloin is already a very uniform shape, you can skip this step. To tie, simply wrap the twine around the tenderloin and tie it securely with a butcher’s knot or a regular knot.
* **Bring to Room Temperature:** Remove the tenderloin from the refrigerator at least 1 hour before cooking, and ideally up to 2 hours. This allows the meat to come closer to room temperature, which promotes more even cooking. A cold tenderloin will take longer to cook through and may result in an unevenly cooked roast – the outside might be overcooked while the center is still undercooked.

### 2. Prepare the Herb and Spice Rub:

* **Combine Ingredients:** In a small bowl, combine the olive oil, fresh rosemary, fresh thyme, fresh oregano, fresh parsley, garlic powder, onion powder, smoked paprika, black pepper, red pepper flakes (if using), kosher salt, and minced garlic. Mix well until all ingredients are evenly distributed and form a paste.
* **Adjust Seasoning:** Taste the rub and adjust the seasoning to your liking. If you prefer more heat, add more red pepper flakes. If you want a more savory flavor, add more garlic powder or onion powder.

### 3. Sear the Beef Tenderloin:

* **Heat the Skillet:** Heat 1 tablespoon of olive oil in a large skillet (cast iron is ideal) over medium-high heat until the oil is shimmering and almost smoking. The skillet needs to be hot to create a good sear.
* **Sear the Tenderloin:** Carefully place the tenderloin in the hot skillet. Sear for 2-3 minutes per side, or until a deep brown crust forms on all sides. Use tongs to turn the tenderloin and ensure even searing. The sear is crucial for developing flavor and creating a beautiful crust. Don’t overcrowd the pan; if your tenderloin is very large, you may need to sear it in two batches. A good sear locks in juices and adds a depth of flavor to the final product. Resist the urge to move the tenderloin around too much while searing; let it sit undisturbed to develop a proper crust.

### 4. Roast the Beef Tenderloin:

* **Preheat Oven:** Preheat your oven to 425°F (220°C).
* **Transfer to Roasting Pan:** Transfer the seared tenderloin to a roasting pan fitted with a rack. The rack allows hot air to circulate around the tenderloin, promoting even cooking. If you don’t have a roasting pan with a rack, you can create a makeshift rack by placing thick slices of onion or carrots on the bottom of the pan.
* **Apply the Herb and Spice Rub:** Generously rub the herb and spice mixture all over the seared tenderloin, ensuring that all surfaces are well coated. Massage the rub into the meat to help it adhere.
* **Roast:** Place the roasting pan in the preheated oven and roast for 20-30 minutes, or until the internal temperature reaches your desired level of doneness (see temperature guide below). The roasting time will vary depending on the size and thickness of the tenderloin, as well as your oven.
* **Monitor Internal Temperature:** Use a meat thermometer to monitor the internal temperature of the tenderloin. Insert the thermometer into the thickest part of the meat, avoiding any bones. Check the temperature frequently during the last 10 minutes of roasting to prevent overcooking. An instant-read thermometer is highly recommended for accurate readings.

### 5. Determine Doneness:

* **Rare:** 120-125°F (49-52°C)
* **Medium-Rare:** 130-135°F (54-57°C) – *Recommended*
* **Medium:** 140-145°F (60-63°C)
* **Medium-Well:** 150-155°F (66-68°C)
* **Well-Done:** 160°F (71°C) and above (not recommended, as the tenderloin will be dry)

Keep in mind that the internal temperature will continue to rise slightly (carryover cooking) as the tenderloin rests. Therefore, remove the tenderloin from the oven when it is about 5°F (3°C) below your desired final temperature.

### 6. Rest the Beef Tenderloin:

* **Tent with Foil:** Remove the tenderloin from the oven and transfer it to a cutting board. Tent loosely with aluminum foil. This allows the meat to relax and the juices to redistribute, resulting in a more tender and juicy roast.
* **Resting Time:** Let the tenderloin rest for at least 15-20 minutes, or even longer (up to 30 minutes) for larger roasts. Do not skip this step! Resting is essential for a juicy tenderloin.

### 7. Make the Pan Sauce (Optional):

* **Deglaze the Pan:** While the tenderloin is resting, prepare the pan sauce. Place the roasting pan on the stovetop over medium heat. Pour in the dry red wine (if using) and beef broth. Use a wooden spoon to scrape up any browned bits from the bottom of the pan. These browned bits are full of flavor and will add depth to the sauce.
* **Reduce the Sauce:** Bring the sauce to a simmer and let it reduce for about 5-10 minutes, or until it has thickened slightly. The sauce should be able to coat the back of a spoon.
* **Finish the Sauce (Optional):** Remove the pan from the heat and whisk in the cold butter, one piece at a time, until the butter is melted and the sauce is smooth and glossy. The butter adds richness and shine to the sauce.
* **Strain (Optional):** For a smoother sauce, strain it through a fine-mesh sieve to remove any solids.

### 8. Slice and Serve:

* **Remove Twine:** Before slicing, remove the kitchen twine from the tenderloin.
* **Slice Against the Grain:** Use a sharp carving knife to slice the tenderloin against the grain. This will shorten the muscle fibers and make the meat more tender.
* **Serving:** Serve the sliced tenderloin immediately, drizzled with the pan sauce (if using). Garnish with fresh herbs, if desired.

## Serving Suggestions:

Herbed and spiced roasted beef tenderloin is a versatile dish that pairs well with a variety of side dishes. Here are a few suggestions:

* **Potatoes:** Roasted potatoes, mashed potatoes, scalloped potatoes, or potato gratin
* **Vegetables:** Roasted asparagus, Brussels sprouts, green beans, carrots, or a mixed green salad
* **Grains:** Quinoa, rice pilaf, or couscous
* **Sauces:** Horseradish sauce, béarnaise sauce, or a simple red wine reduction

## Tips and Tricks:

* **Choose the Right Cut:** Look for a beef tenderloin that is well-trimmed and has a uniform shape. The center cut is the most desirable, as it is the most tender and consistent in size. Ask your butcher for advice on selecting the best cut.
* **Don’t Overcook:** Beef tenderloin is best served medium-rare to medium. Overcooking will result in a dry and tough roast.
* **Use a Meat Thermometer:** A meat thermometer is essential for accurate cooking. It will help you determine when the tenderloin has reached your desired level of doneness.
* **Let it Rest:** Resting is crucial for a juicy tenderloin. Do not skip this step!
* **Sear Properly:** A good sear is essential for developing flavor and creating a beautiful crust. Make sure the skillet is hot before adding the tenderloin, and don’t overcrowd the pan.
* **Adjust the Seasoning:** Taste the herb and spice rub and adjust the seasoning to your liking. Don’t be afraid to experiment with different herbs and spices.
* **Make Ahead:** You can prepare the herb and spice rub up to 24 hours in advance. Store it in an airtight container in the refrigerator. You can also sear the tenderloin up to 2 hours in advance. Let it cool completely before storing it in the refrigerator. Bring it back to room temperature before roasting.
* **Storage:** Leftover roasted beef tenderloin can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in a low oven or microwave.

## Variations:

* **Different Herbs and Spices:** Feel free to experiment with different herbs and spices to create your own unique flavor profile. Some other options include:
* Rosemary and garlic
* Thyme and lemon
* Chili powder and cumin
* Italian seasoning
* **Bacon-Wrapped:** Wrap the tenderloin in bacon before roasting for added flavor and moisture. Secure the bacon with kitchen twine.
* **Stuffed:** Cut a pocket into the tenderloin and stuff it with your favorite filling, such as mushrooms, spinach, or cheese.
* **Different Cooking Methods:** While roasting is the most common method for cooking beef tenderloin, you can also grill it, pan-fry it, or sous vide it.
