Million Dollar Roast Beef Tenderloin: A Luxurious Feast

Serve the roast beef tenderloin with mashed potatoes, roasted vegetables, or a fresh salad for a complete meal.
Store any leftover roast beef in an airtight container in the refrigerator for up to 3 days. Reheat gently to preserve its tenderness.
Variations:

Herb Variations: You can swap rosemary and thyme with other fresh herbs like oregano, sage, or tarragon for different flavor profiles.
Horseradish-Free Option: If you’re not a fan of horseradish, Dijon mustard alone will provide a tangy kick without overpowering the flavor of the beef.
FAQ:

Can I cook this in advance? Yes, you can cook the beef tenderloin a day in advance and store it in the fridge. Just reheat gently before serving to maintain its juiciness.

What’s the best way to check the doneness of the beef? A probe thermometer is the most accurate method. Aim for 120-125°F for medium-rare, 130°F for medium, or 140°F for medium-well.
