Recipe

Ingredients

For the Beef Tenderloin:

• 2-3 pounds beef tenderloin, trimmed
• 2 tablespoons olive oil
• 2 teaspoons salt
• 1 teaspoon black pepper
• 1 teaspoon garlic powder
• 1 teaspoon dried thyme

For the French Onion Au Jus:

• 2 large yellow onions, thinly sliced
• 2 tablespoons unsalted butter
• 1 tablespoon olive oil
• 4 cups beef broth
• 1/2 cup dry red wine (optional)
• 1 teaspoon Worcestershire sauce
• Salt and black pepper, to taste
• Fresh thyme sprigs (for garnish)

Directions

1. Prepare the Beef Tenderloin: Preheat your oven to 400°F (200°C). In a small bowl, mix together the salt, black pepper, garlic powder, and dried thyme. Rub the beef tenderloin with olive oil and then coat it evenly with the spice mixture.
2. Sear the Tenderloin: In a large oven-safe skillet, heat a tablespoon of olive oil over medium-high heat. Once hot, add the beef tenderloin and sear on all sides until browned (about 2-3 minutes per side). Remove from heat.
3. Roast the Tenderloin: Transfer the skillet to the preheated oven and roast the beef for about 25-30 minutes or until it reaches your desired level of doneness (135°F for medium-rare). Once cooked, remove from the oven and tent with foil to rest for 10-15 minutes.
4. Make the French Onion Au Jus: While the beef is resting, use the same skillet to prepare the au jus. Add the butter and olive oil, then add the sliced onions. Sauté over medium heat for about 15-20 minutes until the onions are caramelized and golden brown.
5. Deglaze the Pan: If using red wine, pour it into the pan to deglaze, scraping up any browned bits from the bottom. Allow the wine to reduce for about 5 minutes, then add the beef broth and Worcestershire sauce. Simmer for another 10 minutes, seasoning with salt and black pepper to taste.
6. Serve: Slice the beef tenderloin and serve with the warm French onion au jus drizzled over the top. Garnish with fresh thyme sprigs for added flavor and presentation.

Storing and Preserving

Leftover Roasted Beef Tenderloin can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, slice the beef and warm it gently in a skillet over low heat or in the microwave, adding a splash of au jus to keep it moist. The French onion au jus can also be stored separately and reheated before serving. For longer storage, you can freeze the cooked beef for up to 2 months; however, it’s best to freeze without the au jus to maintain quality.

Common Mistakes and Troubleshooting

1. Overcooked Beef: Use a meat thermometer to check the internal temperature to avoid overcooking. Remove the beef from the oven when it’s about 5°F below your desired doneness.
2. Tough Texture: Make sure to let the beef rest after cooking, as this helps retain its juices and tenderness.
3. Bitter Au Jus: If the onions burn during caramelization, they can impart a bitter taste. Stir frequently and adjust the heat as needed to prevent burning.
4. Thin Au Jus: If the au jus is too thin, simmer it longer to reduce and concentrate the flavors. You can also thicken it with a cornstarch slurry if desired.
5. Lack of Flavor: Taste and adjust the seasoning of the au jus as needed. Fresh herbs or additional Worcestershire sauce can enhance the flavor.

FAQs

1. Can I use a different cut of beef?
   Yes, while beef tenderloin is ideal, you can use cuts like ribeye or sirloin, adjusting the cooking time accordingly.
2. Is it necessary to sear the beef?
   Searing adds flavor and creates a nice crust, but you can skip this step if you prefer to roast it directly.
3. Can I prepare the au jus ahead of time?
   Yes, you can prepare the au jus in advance and reheat it just before serving.
4. What side dishes pair well with this meal?
   Roasted vegetables, mashed potatoes, or a fresh salad are great accompaniments to this dish.
5. How do I know when the beef is done?
   Use a meat thermometer; the beef is medium-rare at 135°F, medium at 145°F, and well-done at 160°F.
