Ingredients You’ll Need:

To make this Million Dollar Roast Beef Tenderloin, here’s a list of everything you’ll need:

1 (3-4 lb) beef tenderloin, trimmed
2 tablespoons olive oil
4 cloves garlic, minced
2 tablespoons fresh rosemary, chopped
1 tablespoon fresh thyme, chopped
1 tablespoon Dijon mustard
1 teaspoon salt
1/2 teaspoon black pepper
1/4 cup unsalted butter, melted
1/2 cup beef broth

The combination of fresh herbs, garlic, Dijon mustard, and the luxurious touch of butter creates a flavor profile that’s both rich and aromatic. The beef broth helps to create a flavorful base, making sure that the roast stays juicy throughout the cooking process.

Preparation

Making this Million Dollar Roast Beef Tenderloin is easy but requires attention to detail to achieve that perfect melt-in-your-mouth tenderness. Here’s how to make it:

Step 1: Preheat your oven to 425°F (220°C). Let it fully heat up while you prepare the beef. You want the oven nice and hot to ensure a beautiful sear and roast.

Step 2: Rub the beef tenderloin with olive oil on all sides. This helps to create a beautiful crust and lock in moisture as it roasts.

Step 3: In a small bowl, combine the minced garlic, chopped rosemary, chopped thyme, Dijon mustard, salt, and pepper. Stir well to form a flavorful paste.

Step 4: Rub the herb and mustard paste all over the beef tenderloin. Be generous and make sure it coats the beef evenly. The Dijon mustard adds a subtle tang that complements the richness of the beef.

Step 5: Heat a large oven-safe skillet over medium-high heat. Once hot, add the beef tenderloin and sear it for 3-4 minutes on each side, or until it develops a golden-brown crust. This step locks in all the flavors and creates a rich, flavorful outer layer.

Step 6: Once the beef is seared, remove it from the skillet. Add the melted butter and beef broth to the skillet, scraping up any flavorful bits stuck to the bottom of the pan. These bits will add depth to the sauce.

Step 7: Place the beef back into the skillet with the broth and butter. Transfer the skillet to the preheated oven. Roast for 25-30 minutes for medium-rare, or longer if you prefer your beef more done. Use a meat thermometer to check the internal temperature (125°F for medium-rare, 135°F for medium).

Step 8: When the roast is done, remove it from the oven and let it rest for 10-15 minutes. Resting the beef allows the juices to redistribute, making it even more tender and flavorful.

Step 9: Slice the roast beef tenderloin into thick slices and serve with the pan juices. This roast is perfect on its own, but you can also pair it with your favorite sides.

Variations

While this Million Dollar Roast Beef Tenderloin is already incredible on its own, there are a few variations and substitutions you can try:

Add More Herbs: Experiment with other herbs like thyme, sage, or tarragon. Fresh herbs give the roast an extra layer of flavor.
Spicy Kick: If you like a bit of heat, try adding a pinch of red pepper flakes or a dash of cayenne pepper to the mustard and herb paste.
Different Mustard: For a slightly different flavor, swap the Dijon mustard with whole grain mustard or spicy brown mustard. Each variety will give the dish a unique twist.
Crust Variations: Add a crust of breadcrumbs mixed with Parmesan cheese and herbs to the beef before roasting. This creates a crunchy exterior that contrasts beautifully with the tender interior.
Vegan Version: If you’re looking to prepare a vegan version, substitute the beef tenderloin with a plant-based roast like a mushroom Wellington or a roasted cauliflower steak, and adjust the cooking method accordingly.

Cooking Notes

Selecting the Right Cut: When choosing your beef tenderloin, look for one that’s well-marbled with fat for the best flavor and tenderness. You can ask your butcher to trim it for you, or do it yourself if you prefer.
Room Temperature Beef: Let the beef come to room temperature before roasting. This ensures even cooking and helps the beef cook more quickly and evenly.
Resting Is Key: Don’t skip the resting time after roasting! This step allows the juices to redistribute, resulting in a juicier, more flavorful roast.
Meat Thermometer: Use a meat thermometer to ensure you achieve your desired level of doneness. For a perfect medium-rare roast, aim for an internal temperature of 125°F (52°C).

Serving Suggestions

This Million Dollar Roast Beef Tenderloin deserves to be paired with elegant sides that complement its richness. Here are a few ideas:

Roasted Vegetables: Serve alongside roasted carrots, parsnips, or Brussels sprouts. The caramelized vegetables add a slightly sweet flavor that balances the savory beef.
Garlic Mashed Potatoes: Creamy mashed potatoes are a classic pairing with roast beef. Add roasted garlic or horseradish for a kick of flavor.
Side Salad: A light salad with mixed greens, fresh herbs, and a tangy vinaigrette helps to cut through the richness of the beef.

Tips

Make-Ahead: You can prepare the herb paste a day in advance and refrigerate it. Simply rub it on the beef just before searing and roasting.
Leftovers: This roast makes excellent leftovers. Thinly slice the beef and use it for sandwiches, wraps, or even a luxurious beef salad.
Storing Leftovers: If you have leftover roast beef, store it in an airtight container in the refrigerator for up to 3 days. You can reheat it gently in a skillet or in the oven with a little broth to keep it moist.
