How to Make Million Dollar Roast Beef Tenderloin Recipe

Step 1: Prep and Tie the Tenderloin

Start by trimming the tenderloin if it’s not already done, then cut it in half for easier handling. Tuck the longer end underneath and use butcher’s twine to tie the meat securely. This step ensures even cooking and gives the roast a beautiful shape. If you want a seriously fantastic crust, season it generously with salt and pepper and leave it uncovered in your fridge overnight or for at least 10 hours. This dry-aging effect is optional but well worth it.

Step 2: Bring to Room Temperature

About two hours before cooking, take your tenderloin out of the fridge and let it rest on the counter. Bringing the meat to room temperature helps it cook more evenly, ensuring that gorgeous juicy center without any cold spots.

Step 3: Sear to Perfection

Preheat your oven to 425 degrees Fahrenheit. While it heats, place avocado oil in a large cast-iron skillet and set it over medium-high heat. When the oil shimmers, carefully sear the tenderloin all over for about 3 to 5 minutes per side. This step locks in juices and forms a rich, golden crust that adds texture and depth to every bite.

Step 4: Prepare the Butter Mixture and Roast

While the tenderloin sears, mix your softened butter, minced garlic, horseradish, and fresh herbs in a small bowl. This butter blend is where the “million dollar” magic comes in — it’s full of flavor and melts into the meat during roasting. Slather this mixture all over your seared tenderloin, then insert a probe thermometer to monitor the temperature closely. Transfer the skillet or place the roast into a baking dish and slide it into your preheated oven. Roast for about 20 to 25 minutes, keeping an eye on your thermometer to hit your preferred doneness.

Step 5: Rest and Slice

Once your roast hits the desired internal temperature, remove it from the oven and transfer it to a cutting board. Let it rest for 15 to 20 minutes — this is crucial for allowing the juices to redistribute throughout the meat, resulting in slices that are juicy and tender instead of dry. Then carve into beautiful one-inch slices and get ready to dazzle your guests.

Garnishes

Presentation is everything when serving your Million Dollar Roast Beef Tenderloin Recipe. Fresh herbs like rosemary or thyme sprigs add a pop of vibrant green and an aromatic finish. A sprinkle of flaky sea salt right after slicing enhances flavor and texture, making each bite even more enticing.

Side Dishes

This roast pairs beautifully with classic sides such as creamy mashed potatoes, roasted seasonal vegetables, or a bright arugula salad tossed with lemon vinaigrette. The richness of the beef and butter calls for sides that either complement with comfort or provide a fresh contrast.

Creative Ways to Present

For a festive touch, arrange the tenderloin slices on a large platter and drizzle with a little of the leftover garlic butter from the pan. Serve alongside mini Yorkshire puddings or atop a bed of caramelized onions for extra elegance. You can also offer horseradish cream or a red wine reduction on the side for guests to customize their experience.

Make Ahead and Storage

Storing Leftovers

Wrap any leftover roast tightly in aluminum foil or place it in an airtight container to preserve freshness. Stored in the refrigerator, it will keep well for up to 3 days and remain moist and flavorful for reheating.

Freezing

If you want to save leftovers longer, slice the tenderloin into portions before freezing. Wrap each portion tightly in plastic wrap and place in a freezer-safe bag or container. This helps maintain texture and flavor, and it will stay good for up to 3 months.

Reheating

To reheat without drying out the meat, warm the slices gently in a low oven (around 300 degrees Fahrenheit) wrapped in foil or use a skillet over low heat with a splash of beef broth. Avoid microwaving whenever possible to keep the tenderloin juicy and tender.

FAQs

Can I use a different cut of beef for this recipe?

While this recipe is crafted for the beef tenderloin’s tenderness and size, you can experiment with other cuts like sirloin or ribeye, but cooking times and results will vary. The tenderloin’s lean texture and flavor perfectly complement the garlic-horseradish butter.

How do I know when the roast is done?

Using a probe thermometer is the best way to check doneness. Aim for about 125°F for rare, 135°F for medium-rare, or 145°F for medium. Remember the roast continues to cook slightly while resting.

Is it necessary to tie the tenderloin?

Tying helps the roast keep a uniform shape, ensuring even cooking and a prettier presentation. It’s a simple step that makes a big difference in the final result.

Can I prepare the butter mixture ahead of time?

Absolutely! You can mix the garlic, horseradish, herbs, and butter a day in advance and keep it refrigerated. Bring it to room temperature before using so it spreads easily.

What if I don’t have avocado oil?

Avocado oil is recommended for its high smoke point, but you can substitute with other neutral oils like grapeseed or light olive oil. Just avoid oils with low smoke points to prevent burning during searing.
