Pork tenderloin is one of those proteins that is luxurious enough for a fancy dinner as it is quick and easy for a healthy weeknight dinner. It is the most tender part of the animal and the leanest. It is the filet mignon of pork. That means it’s the most tender as well as the leanest. 

Since it is so lean, it can easily be overcooked and become dry and chewy. That’s where sous vide cooking comes in. You set the temperature you want it cooked, add seasonings and flavors you want the pork to take on and the rest of the work is done for you while you relax. The result is extremely juicy pork tenderloin that is super tender and has tons of flavor. 

As wonderful as searing and roasting a pork tenderloin after it has been brined is (check out the brined pork tenderloin recipe). This sous vide pork tenderloin recipe is my new favorite for a few reasons.

Why You’ll Love It

  1. Sous vide is the best way to cook pork tenderloin. It is perfectly cooked from the outside to the inside. It is impossible to overcook it. 
  2. Stress-free and pretty much totally hands-off.
  3. It’s healthy. There’s no fat added unless you choose to when searing.

Temps and Times

Like steak, pork can be cooked to your favorite temperature. I recommend 139° F / 59° C as the optimal temperature for super tender and juicy texture. The pork tenderloin pictured in this post was cooked at 139° F for 1 1/2 hours. See chart below for all the temperature options.

How Long to Cook it Sous Vide

There is a nice big cooking time window between 1 hour and 4 hours where the results will be the same. I recommend 1 1/2 hours, but it’s whatever is convenient for you.

Do you Need to Brine the Pork Before Sous Vide?

Nope! Brining pork tenderloin is not necessary when cooking it sous vide. You just need to season it with enough salt that this process will take place naturally when it is cooking sous vide. Check out this Brined Pork Tenderloin recipe if you are interested in brining pork tenderloin for roasting, smoking, or grilling. Or you can try a dry brine like with this smoked pork loin.

How to sous vide pork tenderloin

Don’t be afraid to season it. You need to be very liberal with the salt. 

  1. Season the pork tenderloin very liberally with kosher salt & freshly ground pepper. Place it in the vacuum seal bag or a ziplock bag, then place a few sprigs of fresh thyme and rosemary on each side of the tenderloin. Seal the bag in your vacuum sealer or using the water displacement method.
  2. Sous vide in the water bath at the desired temperature and for the desired time according to the chart (I recommend 139° F for 1 1/2 hours). Remove the bag from the water bath and the tenderloin from the bag. Pat it dry with paper towels. 
  3. Sear it in a very hot skillet with enough canola oil to coat the bottom of the pan for about 30 seconds per side, 2 minutes total. Put a tablespoon or two of butter in the skillet along with some more fresh thyme and rosemary as the tenderloin sears. Baste the butter and herbs over the pork to add extra flavor.
  4. Rest the pork for just a few minutes before slicing and serving.

Sauce Ideas

Sous vide pork tenderloin is so flavorful by itself that a sauce isn’t completely necessary. If you do want to kick it up and elevate the dish; the pork tenderloin pairs wonderfully with a bright and fresh chimichurri sauce, quick pan sauce (see below) or a mushroom sauce

How to make a pan sauce for sous vide pork tenderloin

Making a pan sauce after searing the pork is the quickest way to elevate your dish without having to make a sauce separately. Once the pork is out of the skillet, add in a little chopped shallot. Once the shallot is softened, add about 1/2 cup of dry white wine and cook down until most of the wine is evaporated. Pour in any leftover juices from the sous vide bag and swirl in some butter. Taste for seasoning and serve over the top of the pork.

Pork tenderloin for a crowd

What to serve with the sous vide pork tenderloin

Sous vide mashed potatoes are pretty amazing. They are cooked at a much higher temperature than the pork tenderloin, so you will have to cook them first and they can stay warm in the water while the pork cooks. 194 degrees F for 45 minutes with diced-up potatoes, milk, butter and seasoning right in the bag.

Also wonderful are buttery carrots, crispy brussels sprouts, sous vide polenta, or even a baby arugula salad with a bright vinaigrette. Make some velvety sous vide crème brûlée for dessert.

What to make with leftover pork tenderloin

If you are lucky enough to have some leftovers, you are in for a treat. One of the best ways to enjoy the sous vide pork tenderloin the next day is to make a sandwich the next day on crusty bread with a little mayo and BBQ sauce. That’s all you need and it is soooo good.

    I did this recipe last night. It was unbelievably GREAT! Just wow. I have rarely found a recipe that I was this impressed with! It was my first use of sous vide tool. I’ve had it for a couple of weeks but because of how long it takes to cook meat I haven’t used it yet! I will make this again and again! I followed this to a T and I put more salt on the tenderloin before I cooked it than I normally would because of what the recipe said about salt. It was amazing!!!!

    1. So glad to hear it, Wendy! Agree that it can seem at first like it takes a long time to cook meat. But once you try it you realize it’s totally hands-off and actually takes less of your time than traditional cooking methods. 🙂

  2. Perfection! A tbsp of butter with a sprig of thyme and rosemary in my cast iron pan until browned on all sides, tented with foil while tossing a salad…This will now be my go to pork tenderloin recipe.

    1. Hi Wayne! You can rest it for 10 minutes before searing which will lower the temperature slightly so the internal temperature will rise slightly less when you sear. Other than for that reason, there’s no reason to rest the meat like you would a traditionally cooked pork tenderloin. Cheers!
