    8 Smoked Beef Tenderloin

    🍽️ Why This Works

    Tender – This cut of meat comes from along the spine of the cow and its location is why this meat is so tender. It is a premium cut of beef and highly sought after.

    Simple – This is a simple seasoning, smoking and searing recipe. We’ll walk you through the easy steps and you’ll love the end results. If you can sprinkle salt and pepper on meat and wrap it, you can smoke this to perfection.

    🐄 Ingredients

    Just a Few Ingredients for a Classic Smoked Beef Recipe

    Beef Tenderloin – This was a six pound cut of meat that we picked up at Costco. It is long and fairly narrow. If you can’t find tenderloin, read up on Tenderloin vs Filet Mignon to see if the alternative would work for you. Filet is found just about everywhere and is equally succulent cut of meat.

    SPG – This is a simple rub of salt, pepper and garlic powder. I make a large batch ahead of time and keep it in a mason jar with a tight lid.

    Hickory Wood – This cut does well with a stronger, more intense wood smoke flavor. I had some extra Hickory chunks and thought those would be perfect. Mesquite would work well here too. If you haven’t experimented with different wood smoke before, take a look at this free wood smoking chart to get you started.

    ⏲️ Equipment and Tools

    Baking Rack – I used to just put the meat on the grill set up with indirect heat. I use the Big Green Egg primarily, and would set up the plate setter. The problem was that the meat would drip juices and cause unwanted smoke. I moved to an elevated baking rack in a sheet pan and it made all the difference in the world.

    The rack is elevated slightly, which allows the smoke to reach all sides of the meat, and the sheet pan catches any drippings. Winner winner!

    This is not necessary though! As long as you a clean grill grate, you can certainly place it on that. We are in love with the rack right now though.


    Wireless Meat Thermometer – You will want to closely monitor the temps of this tenderloin. I use the ThermoPro TP20, but I reviewed several thermometers if you want a more in depth analysis.

    Butcher’s Twine – This can be found just about everywhere in the kitchenware department. Our small, local grocery store has it, Walmart carries it and you can always skip the stores and order from Amazon.

    Smoke, Sear and Serve Instructions

    Step One: Trim any extra fat and remove the silver skin.

    Step Two: There are two options for dealing with the tenderloin’s size.

    • Cut the Meat: You can open up the package and lay the meat our flat. Then, cut it to size, trimming the ends to keep a uniform thickness for the grill. The benefit of that is your final product will be of similar size and definitely gorgeous, but you’ll have to find something else to do with the sections you cut off.
    • Truss the Meat: This is the path I took. Fold the beef over on itself so the new length is of a manageable size, and tie it off with butcher’s twine. I measured it against the size of a quarter sheet pan, as that is what would fit comfortably on the grill. I was able to fold over the thin end to double up its thickness. I included photos of the steps above. The benefit is that I did not have to worry about finding something else to do with the extra pieces.

    Step Three: Mix your SPG together. This salt, pepper and garlic mix is a classic seasoning and doesn’t overpower this beef.

    Step Four: Season the tenderloin with the SPG, turning it over to make sure you cover it all evenly.

    Step Five: Set up the grill for indirect heat at 275 degrees. For the kamado grills, use a plate setter. For gas grills, turn off the center burners.

    Step Six: Add the smoking wood. If you have a gas grill, use a smoking box instead.

    Step Seven: Insert the temperature probe and place the tenderloin on the grill. Let it gently smoke until the internal temperature reaches 130 degrees.

    Step Eight: When the beef reaches 130 degrees, it is time to sear it. Remove the meat and set up the grill for direct heat. Carefully remove the plate setter (it’s hot!). Place the tenderloin directly on the grill grate and let it sear for about three minutes on each side. The temperature will quickly rise, and remove it when it reaches 140-145 degrees.

    Step Nine: Bring it inside and let it rest under an aluminum foil tent for ten minutes. This will help to keep the juices inside when you slice it.

    ❗ Expert Tips

    Truss the Tail – You can cut off the thin piece of the tenderloin (called the tail, even though it isn’t a tail), but it perfectly fine to tuck it under the thicker portion and truss it off with butcher’s twine.

    Season Lightly – This is one of those recipes where you really don’t want to overpower the flavor of the beef. Keep the seasoning light and simple.

    Store Leftovers – This was way too much meat for us, so we let it cool, and then sliced it into smaller pieces and stored in Ziploc freezer bags. The wonderful smoke flavor intensifies and the kitchen smells so good when we reheat it!

    🥦 Side Dishes

    Don’t forget about grilling a delicious side dish to serve with this. The grill will be set up for direct heating after you remove it for resting, so consider a few recipes that you can whip up while it rests.

    You can keep it simple and just grill some sweet onions. These work well as the flavors won’t overpower the tenderloin, and they don’t take very long to cook. Or, consider some grilled baby potatoes for that extra starch. Those can be ready in just 20 minutes and will be piping hot when the beef is ready to slice.

    My favorite is grilled root vegetables. While the beef is smoking, cut up the parsnips, turnips, potatoes, rutabagas and anything else you want to throw in. This is a phenomenal combination of sweet and tangy that works just perfectly with this recipe.

    Recipe FAQ

    What is a Reverse Sear?

    This is a two step process that is often used for thick pieces of meat. First, cook the meat using indirect heat. This will allow the beef to slowly come up to temperature. Second, you will move the meat to a direct heat source that will sear the outside of the beef and provide that delicious, caramelized texture that we all love! It allows the outside of the beef to cook quickly.

    What internal temperature should I cook beef tenderloin to?

    I kept this to about 140 degrees, for a nice medium rare, but cook it to the desires of your guests. This cut of beef is so tender that it can afford to be cooked a bit more if you want.

    How long does it take for a beef tenderloin to smoke?

    At 275 degrees, it should take about an hour for the internal temperature to reach 130 degrees. Then, it is time to finish the recipe using the direct sear techniques until the internal temperature reaches your desired level of doneness.

    Equipment

    • Baking Rack
    • Wireless Meat Thermometer
    • Butcher's Twine

    Ingredients

    • 6 lb Beef Tenderloin

    SPG Seasoning

    • 4 tbsp Kosher Salt
    • 2 tbsp Garlic Powder
    • 1 tbsp Coarse Ground Pepper

    Instructions

    Make the SPG

    • Combine the salt, pepper and garlic in a jar. Cover and shake to mix well.

    Preparation

    • Cut off any large chunks of fat and remove the silver skin.
    • Fold the thin end of the tenderloin over and secure it with butcher's twine. This will help the beef retain its shape as it cooks.
    • Sprinkle the SPG over the beef. Make sure you get all sides.

    Smoking

    • Set up the grill to indirect heat and bring the temperature to 275 degrees. Add your wood chunks. We used Hickory.
    • Place the beef on a raised baking rack on a sheet pan and place it on the grill.
    • Let the beef smoke gently until the internal temperature reaches 130 degrees.

    Searing

    • When the temperature reaches 130 degrees, remove the tenderloin and reconfigure the grill for direct heat.
    • Remove the beef from the baking rack and place it straight on the grill grate to sear the exterior.
    • Turn the beef every two to three minutes, making sure to sear all sides, until the internal temperature reaches your target. I removed mine at 140 degrees for a solid medium rare.
    • Bring the tenderloin inside and tent it with foil, letting it rest for 10-15 minutes.
    • Slice and serve!

    Notes

    Reverse Searing: This is a two step process that is often used for thick pieces of meat. First, cook the meat using indirect heat. This will allow the beef to slowly come up to temperature. Second, you will move the meat to a direct heat source that will sear the outside of the beef and provide that delicious, caramelized texture that we all love! It allows the outside of the beef to cook quickly.
    Internal Temperature: 140 degrees, for a nice medium rare, but cook it to the desires of your guests. This cut of beef is so tender that it can afford to be cooked a bit more if you want.
    How Long to Smoke: At 275 degrees, it should take about an hour for the internal temperature to reach 130 degrees. Then, it is time to finish the recipe using the direct sear techniques until the internal temperature reaches your desired level of doneness.
    Silver Skin: Make sure to cut off the excess silver skin but try to keep on some of the fat. 
    Storage: This can be stored in the refrigerator for up to 3 days in a sealed container or ziploc bag. 
    Freezer Friendly: Freeze this by double wrapping it and placing in a freezer safe ziploc bag. We defrosted in the refrigerator and zapped in the microwave for the ultimate in tender leftovers.
