What’s in This Smoker Recipe

The best thing about this traeger smoked beef tenderloin recipe is how simple it is to make. Just a handful of ingredients, and you’re on your way to a delicious culinary experience!

Including the beef, you only need 5 ingredients for this smoked beef tenderloin recipe.

Beef Tenderloin – This cylindrical shape beef is where filet mignon steaks come from and thus, it is one of the most expensive cuts of meat. Therefore, you’re going to want to make sure you’re getting a good one.

If you’re wondering how to pick out a beef tenderloin, it’s pretty simple. keep the following tips in mind.

  • Look for one that is deep red.
  • You want one that is “tight.” This just means that the meat is not stringy. A tight cut of beef will prevent you from having to use butcher’s twine to hold it together.
  • It’s not necessary for it to be marbled. This is a very tender and lean cut of meat. (Which makes it an expensive cut of meat as well!)

The Seasoning – You can go as simple as kosher salt and ground black pepper. But we like to kick things up a bit. Some great ideas for seasoning a beef tenderloin can include:

  • Montreal steak seasoning.
  • Garlic powder and/or garlic salt.
  • Fresh herbs are always a good option.
  • Onion powder.
  • Paprika.

Bacon makes everything better! We like to make smoked beef tenderloin wrapped in bacon. It adds great flavor and keeps the meat from drying out during the smoking process.

Expert Tip: Look for thin-cut bacon to wrap around this beef tenderloin before putting it on the grill. I prefer the Kirkland brand from Costco for this recipe. I’ve tried several other brands but their thin strips of bacon stretch really well for this purpose. Read on, and I’ll show you exactly how to do this.

How to Make Smoked Beef Tenderloin on a Traeger

The great thing about this recipe is that you can use this same technique on any smoker using indirect heat. Follow the steps below and the end result will be a beef tenderloin roast with a rich flavor that will soon be a family favorite!

Expert Tip: Before you do anything, take the whole tenderloin out of the fridge and let it sit to help get it closer to room temperature. Putting a cold piece of meat on a hot smoker is never a good idea. For food safety reasons, don’t let it sit out for longer than an hour or so.

Before you season the meat, you’re going to want to trim any silver skin from the meat. Here’s a good video that shows you how to trim silver skin. You’ll want to leave the rest of the meat intact as you’ll be smoking the whole tenderloin.

If your tenderloin isn’t trimmed, you’ll want to remove the silver skin.

While your meat is coming to room temperature, you’ll want to do a few things. Ignite your smoker to an initial temperature of 185 degrees F. Next, you’ll want to season the meat and wrap it in bacon.

Seasoning a whole beef tenderloin and wrapping it in bacon.
  1. Sprinkle a generous amount of Montreal steak seasoning on the whole tenderloin.
  2. Wrap the bacon around the meat, slightly overlapping each slice. Tuck the ends of the bacon together to secure them.
  3. Sprinkle a good amount of garlic salt over the bacon.
  4. Add some paprika for a little bit of extra heat.

Variations and Substitutions

If you want to make your own seasoning, you can use some olive oil and mix it all together in a small bowl.

You can also use a simple dry brine of salt and pepper while you’re waiting to put the tenderloin on the smoker.

Instead of bacon, you can also use prosciutto which is a thin Italian ham. We do this when we make pork tenderloin on the smoker.

Of course, you don’t have to wrap the meat in anything! It’s delicious by itself (and maybe a little creamy horseradish sauce at the end.)

The Cooking Process

After you’re finished prepping the meat and you have a hot grill, it’s time to let your smoker do its magic.

A big piece of meat, wrapped in bacon and then placed on a grill.
  1. Use one of your sheet pans to transfer the whole beef tenderloin to your smoker.
  2. Place the meat on your the smoker grates and insert a temperature probe into the thickest part of the tenderloin.

Let the internal temperature of the meat get to 100° F. This will take about 2 hours, depending on the temperature of your smoke. I like to start this with a smoker temperature of 185° F.

Important Note: If you smoke at a higher temperature, it will take significantly less time!

When the internal temp of tenderloin reaches 100° F., remove the meat from the smoker and tent it with foil. Now, increase the temperature of the smoker to 400°F. When it reaches temp, put the meat back in the smoker.

Remove from smoker when the internal temp reaches 125° F.

Now, you’re going leave the tenderloin on the smoker until it reaches an internal temperature of 125°. Remove the meat at this time. Then place it on a cutting board, tent it loosely with aluminum foil and let it rest for at least 15 minutes before slicing.

This will give you a medium-rare tenderloin. If you want it done a bit more, leave it on the smoker until it reaches 128° to 130° F, depending on how well done you like you beef.

Expert Tips for Smoking a Beef Tenderloin

  • If you’re using a Traeger grill, turn on the super-smoke function if available.
  • Use a smoke tube as shown.
  • Place an aluminum pan under the grate to catch the drippings and grease from the bacon.
  • Place the whole tenderloin on a stainless steel cooling wrack and place the wrack on the grates of your smoker. This makes it super easy to remove the meat when it is finished.

What to Serve With Beef Tenderloin

Similar to the best London broil recipe, this smoked beef tenderloin pairs with almost anything, depending on the occasion.

If it’s a special occasion, consider twice-baked potatoes, a green salad and maybe some roasted Brussels sprouts coated in balsamic vinegar. Or, for a very special dinner, consider making a surf-n-turf meal by adding this seared scallops recipe.

If this is a casual family dinner, you can’t go wrong with mashed potatoes made with garlic, our bacon macaroni and cheese, and maybe some rustic crusty bread. You can serve this with anything that would go well with prime rib.

Common Questions

What are the best woods to use for smoking a beef tenderloin?

This is a matter of personal preference. Many people like to use cherry wood or apple wood for a smoke flavor. My preference is hickory.

Does this have to be seared?

You can reverse sear this if you want but the bacon forms a nice crispy outer layer that gives the beef a perfect savory flavor.

What can I make with the leftovers?

The leftovers from this meal make excellent beef enchiladas or tacos made with leftover steak. You can even substitute leftover beef tenderloin for hamburger and make the best Patty Melt sandwich you’ve ever tasted1
