How to cook a sous vide pork loin

When using a sous vide cooker, it’s important to know that the temperature you set your immersion circulator to is the desired temperature you want your food cooked to.

Sous Vide the Pork

Prep the pork by removing it from the package and patting it dry with paper towels. If your roast has a thick fat cap (over 1/2″) you may want to trim it 1/4″, depending on your family’s preference.

Then, score the fat cap by drawing lines with the tip of a sharp knife about 1/4″ into the fat layer. Rotate the roast and repeat, creating a crosshatch pattern. Next, liberally season the whole roast with kosher salt.

Next, add the pork loin roast to a large vacuum seal bag, making sure there is enough room to seal the bag with a vacuum sealer. Add the rosemary and garlic and remove the air, sealing the sous vide bag. We love our FoodSaver for making quick work of this.

Meanwhile, preheat a water bath with your sous vide machine to 140 degrees F. When the water has come to temperature, slowly add the pork roast, making sure there are no leaks in the bag. We weigh our food down with a mesh anchor when cooking to avoid it floating to the top and cooking unevenly.

Sous vide the pork loin for 4 hours, then carefully remove the bag from the water bath.

Sear and Serve

Allow the pork loin to rest 10 minutes in the bag before opening it up and patting it dry. Meanwhile, preheat a large cast iron skillet over medium-high heat.

When the skillet is just smoking, place the pork, fat side down in the skillet for a quick sear. The fat will immediately start to sizzle. Brown the fat cap for 5 to 7 minutes until golden.

As the fat cap sears, the fat will render. Add the garlic and rosemary to the pan in the drippings. Using a spoon, ladle the fat over the top of the pork.

Then flip the pork and brown all other sides, 3 to 4 minutes.

Carefully remove the sous vide pork roast from the skillet with long tongs. Top with compound butter to melt over the top for extra flavor and slice into 1/2″ thick portions. Sprinkle with a pinch of salt and pepper and freshly minced parsley, and serve hot.

Girl Carnivore Expert Recipe Tips

  • Always use a digital meat thermometer to check the internal temp at the thickest part of the roast to guarantee it’s cooked through. Pork is safe to eat at 145 degrees F, according to the USDA. If the pork is not 140 F degrees in the center when you remove it from the water bath, reseal it in a new bag and continue cooking it for another hour. The thickness and size of your pork loin will determine how long the roast needs in the sous vide water bath.
  • For a more pleasing presentation, secure your pork roast with butcher’s twine every 1 to 2 inches for a more round shape when sliced and served.
  • We recommend a vacuum-sealed bag and a vacuum sealer over a Ziploc bag or freezer bag as the most foolproof way to avoid any leaks.
  • Use pan drippings to make a mustard cream sauce. Once your pork has been removed from the pan, drain the fat and create a delicious pan sauce with the fond.

What to serve with sous vide pork

This pork loin recipe is perfect with your favorite side dishes like creamed spinach, Brussels sprouts au gratin, baked potatoes, and even smoked cabbage and quick air fryer vegetables if you’re pairing it with the mustard sauce.

Wine Pairing:

We pair our pork loin with light red wines like Pinot Noir or an oaky yet buttery white wine like a Chardonnay.

Wrap any leftover pork tightly in aluminum foil and, when cooled, store in the fridge for up to 3 to 4 days.

To reheat, slice off what you need and wrap the slices in foil. Preheat the oven to 325°F and place the foil-wrapped slices in the oven to reheat for 10 to 15 minutes, until heated through.
