When elevating a special occasion there is nothing more fabulous than grilling a whole Beef Tenderloin Roast. The whole Tenderloin is incredibly tender and rich with a decadent Beefy flavor. The presentation is absolutely beautiful. Follow along as we walk through the cut and the best way to grill it using high heat.

Beef Tenderloin

We go into more detail about this cut in our Smoked Beef Tenderloin recipe. But as a quick reminder, this tender Roast comes from just off the spine area of the cow. The flavor profile is rich, that is because the muscle fibers do not see as much movement as a brisket or Chuck Roast. It is incredibly tender because of less connective tissue. That means it can cook very quickly, so paying attention throughout the cooking process is important.

It’s an expensive cut of meat and so to save money you can often buy the entire Beef Tenderloin that has yet to be trimmed. It’s also the most tender cut of beef.

Fun fact: After being trimmed down into individual steaks, the Tenderloin is where the Filet Mignon comes from.

Related Recipe: If you want to know the second most tender cut of Beef, it’s the Flat Iron Steak from the Chuck Primal.

Ingredients

• Trimmed Beef Tenderloin Roast
• Olive Oil and Beef Seasoning
• Roux – Equal parts unsalted butter and flour
• Whole Milk – Heavy cream makes the sauce too thick
• Whole Grain Dijon Mustard – Gives the right balance of acidity, but any mustard will work
• Horseradish Cream – Adds heat
• Mustard Seed – Adds more of the mustard bite and texture

Trimming

If you can’t source a pre-trimmed and ready Tenderloin roast at grocery stores then you can often find a full Beef Tenderloin, which will need to be trimmed up prior to grilling. There are three parts to the full Roast – the chain, the tail, and the Roast itself. Using a sharp knife and your cutting board:

1. Remove the tail. I remove it at the point the width of the Roast is the same.
2. Remove the chain. Using my knife I gently cut along the silver skin and seam. As I remove the chain the Roast itself starts to take shape. On the opposite side of the chain there may be some larger portions of the roast that also need to be removed.
3. Trim the roast. Remove any excess fat and silver skin. The Roast should be roughly 12-inches long and even.

Use the trimmed meats for other recipes, like our grilled steak bites with wine sauce, beef kabobs, or freeze them for future use.

Seasoning

If you want to go simple use a basic beef seasoning with equal parts kosher salt, granulated garlic, and coarse black pepper. For this recipe we are actually elevating the flavor with more savory and herbal flavors using our beef seasoning. Coat the outside of the Tenderloin with olive oil and then liberally apply the seasoning. Then it’s ready to grill.

A note about bringing Beef to room temperature – Some say that you should allow the Beef Roast to sit for an hour to come to room temperature. The reality is that any cut of meat is not going to come to “room temperature” in one hour. The internal portion of the Beef will still be 45 degrees while you run the risk of bacteria forming on the outer side of the Roast. Save yourself the hassle and time and just crank up the heat of your grill.

How to Grill Beef Tenderloin

The easiest way to get a good sear and the perfect temperature is to sear hot and fast over hot direct heat and then finish over indirect heat to your desired finishing temperature.

1. Prepare your grill for two-zone grilling (or direct and indirect grilling). Target the inside of the grill at 500 degrees F. Place Beef Roast on the grill grates over direct heat. Grill direct over the high temperature for 5 minutes and then rotate the Roast and continue grilling direct for 5 more minutes. Because of the shape of the Beef Tenderloin, it tends to be like a triangle. So grill the last side for 3-5 additional minutes (to make sure there’s a good sear on all sides).
2. After all three sides were grilled move the Roast to indirect heat, which is the cooler side of the grill. Continue grilling at 500 degrees F. The internal temperature of the meat will continue to rise. Monitor this stage closely by using a good high-quality instant read meat thermometer. Pull the meat at your desired finishing temperature. We recommend medium-rare for this cut.
3. Pull the Roast and then let the meat rest for 10 additional minutes. As it rests the internal temperature of the steak will continue to rise an additional 5 to 7 degrees. So be sure you pull the roast at a temperature you like and account for the additional temperature increase. If you want your steak at 145 degrees F then pull the Roast between 136 to 138 degrees F.

Gas Grill – If using a gas grill be sure to follow the same steps. Light one or two burners as your direct heat and finish over indirect side.

Slicing and Plating

After the rest use a good carving knife on a carving board or cutting board to slice the Roast into 1-inch slices. If serving family style garnish with a bundle of fresh herbs. Serve the mustard steak sauce in a small bowl with a spoon.

Mustard Steak Sauce

For our mustard steak sauce ingredients, we are using a thickening roux and then combining mustard with milk and finishing with our seasoning. This provides a nice balance of richness and acidity that pairs well with the flavors of the Grilled Beef Tenderloin. The whole sauce should come together in less than 10 minutes. We typically make the sauce while the Beef Roast is resting.

1. In a small sauce pan over medium heat melt butter and then add the flour. Stir to combine and continue stirring for 1 minute until it starts to bubble for 30 seconds. This activates the roux. Add the milk and continue to stir often over medium heat until the milk starts to thicken into a pancake batter consistency.
2. Turn off the heat and then add the remaining ingredients. Stir to combine.

Place the finished mustard steak sauce in a small bowl for serving. Serve warm.

Wine Pairing With Beef Tenderloin

Because the Roast is lean with less intramuscular fat a balanced red wine with less tannin is best. Add the acidity from the mustard steak sauce and our go to pairing with this Grilled Beef Tenderloin is Syrah or Merlot.
