Smoking usually takes hours and hours, but the tender nature of this cut of meat makes the process a whole lot shorter. In fact, when starting from room temperature, it only takes about 2 hours for this roast to take on a lovely smoky flavor and be cooked to perfection.

I use my Traeger pellet smoker for this job. It gives everything a lovely flavor and lets me control the temperature at the same time.

I promise you – invest in this cut of meat and smoke it. You’ll never look back!

How to Buy Beef Tenderloin

Beef tenderloin is expensive, there’s no doubt about it. BUT, there are ways to make this a bit cheaper.

  1. Purchase beef tenderloin when it’s on sale. Beef tenderloin often goes on sale around the holidays. Buy it when it goes on sale and wrap it tightly in foil then put it into a freezer-friendly zipper-top bag and freeze it for up to six months.
  2. Buy beef tenderloin whole and butcher it yourself. Not only is this the most economical way to buy a beef tenderloin, but you get the added bonus of having all the amazing beef tenderloin to work with, including prized filet mignon steaks.
  3. My favorite way – buy the WHOLE tenderloin when it is on sale. I’ll buy a few of them this way, and they’re cryovaced so they’ll freeze fine for quite a few months.

How To Make Traeger Beef Tenderloin

  1. Combine the Dijon, minced garlic, brown sugar alternative, whisky, and Worcestershire sauce in a small bowl.
  2. Coat the beef tenderloin with the mixture and put it on the smoker that’s preheated to 180-F.
  3. Smoke the beef at 180-F for 1-2 hours until it comes to an internal temperature of 125-F. Use a good digital thermometer to get an exact reading – you don’t want to overcook this king of all meats!
  4. Let it rest for 10 minutes, then slice and serve.

Chef Jenn’s Tips

  • Do not freestyle this smoked beef recipe without a digital thermometer. There’s nothing that’ll make me cry faster than overcooking a beef tenderloin roast.
  • Pull your roast out to rest when it hits 125-F for medium rare, or 130-F for medium. I don’t recommend cooking this roast beyond 130-F.
  • Don’t reheat this roast if you have some leftover, as it’ll probably overcook. Enjoy leftovers sliced on a chaffle like this French Dip Chaffwich, or serve chilled slices with your favorite sides for lunch the next day.

What To Serve with Easy Smoked Beef Tenderloin

With all the work being done by the smoker, you are freed up to make some killer sides. And, you’re working with the king of meats, so go all out with fancy sides like this amazing antipasto salad, a tasty Brussels sprouts dish, or something creamy like this spinach dish.

Don’t forget the Horsey Sauce, a must with this or any meat dish!

Is This Easy Keto Beef Recipe Freezer Friendly?

Well, you can freeze it, but smoked beef tenderloin doesn’t heat up as nicely. You run the risk of overcooking it. So, if you freeze it, let it thaw in the fridge and serve chilled, or just enjoy this dish fresh without freezing it.

How do you cook a beef tenderloin?

You can roast beef tenderloin or grill it, but my favorite way is to smoke beef tenderloin!

Is beef tenderloin keto?

Heck yes! Go to town on this beefy favorite that’s loaded with protein and great nutrition.

Do you cover beef tenderloin when cooking?

No! Some meats need to be covered to help them cook, especially if there’s a lot of fat or connective tissue. But this lean cut of meat needs dry heat with little moisture to make it nice and tender.
