We often brine lean meats like smoked pork tenderloin however, this time I changed it up and injected butter instead and yes, it was something to write home about.

These lean, delicious cuts cook up quick in the smoker and they can even handle being cooked a little higher if you want to get them done faster.. can't beat a deal like that.

About Smoked Pork Tenderloin

These cuts usually weigh in at about 16-18 ounces each and you should be able to feed 5 people with 2 pork tenderloins. If you want leftovers, throw on an extra one.

It may be helpful to note that these are nearly always sold two pork tenderloins per package.

The meat is very lean and rivals other lean meats such as chicken breast in “healthiness”.

Step 1: Remove the Silver Skin

I recommend spending some time removing some of the tough skin and/or fat on the outside of these using a very sharp knife.

After:

Step 2: Inject with Butter

I don't inject meat very often but when I do, I have learned to always cover it with a piece of plastic.. I don't like wearing whatever I'm injecting.

Just use cling wrap or similar plastic food wrap and place it over the top of the meat you are injecting to prevent a geyser of warm melted butter from hitting you in the face.. been there, done that!

Fill the injector with warm melted butter then insert the needle through the plastic into the meat at about a 45° angle and depress the plunger to inject some of the butter into the meat.

You will see the meat plumping up where the butter is going in and it may also find a way to seep out somewhere, this is normal.

You may feel like all of it is coming out but it's not. Much of it stays in and that's what matters.

Inject butter into the meat about every 2 inches or so.

Step 3: Seasoning

When I got finished injecting these, there was butter that had seeped out onto the outside of the pork tenderloins and this worked great as a binder.

First I placed the tenderloins into a foil pan.

Then I liberally coated all sides of each one with my Texas style rub (Purchase formula here | Purchase bottled rub).

It's not very salty so you can use plenty.

Step 4: Into the Fridge

I recommend at least 2 hours of refrigeration but overnight is also great.

During this time the butter inside the meat hardens.

Step 5: Smoke Time

Setup your smoker for cooking at about 225°F using indirect heat. If your smoker uses a water pan, fill it up.

I often get asked about using water pans in pellet smokers and while I have tried this, I don't find it necessary. If you use a water pan in your pellet smoker and it seems to work well for you, then please continue.

I used the Hasty Bake Legacy for these smoked pork tenderloins which does not utilize a water pan.

When the smoker is ready, place the pork tenderloins on the grate to cook.

I used a few pieces of cherry wood which worked great but other woods such as oak, pecan, apple, hickory, etc. will also work just fine.

If you maintain 225°F you can expect the tenderloins to take about 2 hours to reach 145°F in the thickest part.

Note: Some so-called barbecue afficianodos online recommend you cook lean pork such as tenderloins and loin to 160°F. Please, in the name of everything that is good and lovely, do not, I repeat, do not, cook these to 160°F.

Brining helps, but at 160°F, pork tenderloin will be dry, tasteless and definitely not as good as it was 15 degrees earlier. Multiple studies and tests have been performed and pork is completely safe to eat at 145°F and even lower than that with ample rest periods.  Don't let fear of something that no longer exists stop you from enjoying these at their prime finish temperature.

Okay, rant over.

I think the butter helps a lot in making sure these end up juicy and tender. One thing to keep in mind is that these are also pretty versatile and can handle higher, even grilling temperatures, if you're in a hurry. At 275-300°F, you should be able to get them done in about an hour.

Step 6: Sear (optional)

I love putting a sear on any meat I am cooking on the Hasty Bake.. it's such an easy thing to do since you simply raise the charcoal pan and remove the heat deflector.

You can also use a gas grill, griddle or even the broil function on your oven to sear these.

To sear: When they reach an internal temperature of about 135°F in the thickest part, place them over high heat and let them brown to your liking on all sides. Make sure they reach 145°F and call them done.

IMG 1509

Step 7: Finish and Slice

Resting after searing is always a great idea, just tent some foil over the meat for a few minutes while the temperature settles down and the juices redistribute throughout the meat.

When ready, slice the meat into pencil thick slices and serve immediately.
