this Recipe

Ingredients:

• Beef Tenderloin: 3-4 lb, trimmed of silver skin and excess fat
• Olive Oil: 2 tablespoons, extra virgin
• Garlic: 4 cloves, minced
• Fresh Rosemary: 2 tablespoons, chopped
• Fresh Thyme: 2 tablespoons, chopped
• Kosher Salt: 2 teaspoons, or to taste
• Black Pepper: 1 teaspoon, freshly ground, or to taste
• Dijon Mustard: 2 tablespoons
• Beef Broth: 1 cup
• Dry Red Wine: 1/2 cup (Cabernet Sauvignon or Merlot recommended)
• Butter: 2 tablespoons, unsalted
• All-Purpose Flour: 1 tablespoon

Preparing the Beef Tenderloin:

1. Bring the Beef to Room Temperature: This is crucial for even cooking. Take the beef tenderloin out of the refrigerator at least one hour before you plan to cook it, and ideally up to two hours. This allows the internal temperature to rise, resulting in a more evenly cooked roast. Don’t worry about it spoiling; two hours at room temperature is perfectly safe.
2. Preheat Your Oven: Preheat your oven to 450°F (232°C). High heat is essential for searing the outside of the tenderloin, creating a beautiful crust. Make sure your oven is fully preheated before you put the beef in.
3. Prepare the Herb Mixture: In a small bowl, combine the minced garlic, chopped rosemary, and chopped thyme. This aromatic mixture will infuse the beef with incredible flavor.
4. Season the Beef: Pat the beef tenderloin dry with paper towels. This helps to ensure a good sear. Generously season the beef on all sides with kosher salt and freshly ground black pepper. Don’t be shy with the seasoning; it’s what gives the beef its flavor.
5. Sear the Beef: Heat the olive oil in a large, oven-safe skillet over medium-high heat. The skillet should be large enough to accommodate the entire tenderloin without overcrowding. Once the oil is shimmering and hot, carefully place the beef tenderloin in the skillet. Sear it for 2-3 minutes on each side, until a deep brown crust forms. This searing process is key to locking in the juices and creating a flavorful exterior. Use tongs to turn the beef and sear all sides, including the ends.
6. Apply the Herb Paste: Remove the skillet from the heat. Spread the Dijon mustard evenly over the seared beef tenderloin. Then, press the herb mixture onto the mustard-coated beef, ensuring it adheres well. The mustard acts as a binder for the herbs and adds a subtle tang to the flavor profile.

Roasting the Beef Tenderloin:

1. Roast in the Oven: Place the skillet with the beef tenderloin in the preheated oven. Roast for 18-22 minutes for medium-rare, or longer for more well-done. The exact cooking time will depend on the size and thickness of your tenderloin, as well as your desired level of doneness.
2. Use a Meat Thermometer: The best way to determine the doneness of the beef is to use a meat thermometer. Insert the thermometer into the thickest part of the tenderloin, avoiding any bone. Here are the target internal temperatures for different levels of doneness:
   • Rare: 125-130°F (52-54°C)
   • Medium-Rare: 130-135°F (54-57°C)
   • Medium: 135-140°F (57-60°C)
   • Medium-Well: 140-145°F (60-63°C)
   • Well-Done: 145°F+ (63°C+)
3. Rest the Beef: Once the beef reaches your desired internal temperature, remove the skillet from the oven. Transfer the beef tenderloin to a cutting board and tent it loosely with foil. Let it rest for at least 10-15 minutes before slicing. This resting period allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful roast. Don’t skip this step!

Making the Red Wine Sauce:

1. Deglaze the Pan: While the beef is resting, prepare the red wine sauce. Place the skillet you used to sear the beef back on the stovetop over medium heat. Pour in the dry red wine and use a wooden spoon to scrape up any browned bits from the bottom of the pan. These browned bits, called fond, are packed with flavor and will add depth to the sauce.
2. Reduce the Wine: Let the wine simmer and reduce by about half, which should take about 5-7 minutes. This concentrates the flavor of the wine and creates a richer sauce.
3. Add Beef Broth: Pour in the beef broth and continue to simmer for another 5-7 minutes, or until the sauce has thickened slightly.
4. Make a Slurry: In a small bowl, whisk together the melted butter and all-purpose flour to create a slurry. This slurry will help to thicken the sauce.
5. Thicken the Sauce: Slowly whisk the butter-flour slurry into the simmering sauce. Continue to whisk until the sauce thickens to your desired consistency. This should only take a minute or two.
6. Season to Taste: Taste the sauce and adjust the seasoning as needed. Add salt and pepper to taste. You can also add a pinch of sugar if you prefer a slightly sweeter sauce.
7. Strain the Sauce (Optional): For a smoother sauce, you can strain it through a fine-mesh sieve before serving. This will remove any small bits of herbs or garlic.

Slicing and Serving:

1. Slice the Beef: After the beef has rested, remove the foil and slice it against the grain into 1/2-inch thick slices. Slicing against the grain shortens the muscle fibers, making the beef more tender and easier to chew.
2. Serve with Sauce: Arrange the sliced beef tenderloin on a platter and drizzle generously with the red wine sauce.
3. Garnish (Optional): Garnish with fresh rosemary sprigs or thyme sprigs for a beautiful presentation.
4. Serving Suggestions: Serve the roast beef tenderloin with your favorite side dishes, such as roasted potatoes, asparagus, green beans, or mashed potatoes. A simple salad also makes a great accompaniment.

Tips for Success:

• 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 to ensure accurate cooking.
• Use High-Quality Ingredients: The quality of the beef tenderloin will greatly impact the final result. Choose a high-quality cut of beef from a reputable butcher or grocery store.
• Let it Rest: Resting the beef is crucial for retaining its juices and ensuring a tender roast. Don’t skip this step!
• Adjust Seasoning: Taste the sauce and adjust the seasoning as needed. Don’t be afraid to experiment with different herbs and spices to create a flavor profile that you love.
• Make Ahead: The red wine sauce can be made ahead of time and reheated before serving. This can save you time on the day of your dinner party.

Variations:

• Mushroom Sauce: Substitute the red wine sauce with a creamy mushroom sauce for a different flavor profile.
• Garlic Herb Butter: Instead of Dijon mustard and herbs, spread the beef with a garlic herb butter before roasting.
• Bacon-Wrapped: Wrap the beef tenderloin in bacon before searing for added flavor and moisture. Secure the bacon with kitchen twine.
