Whenever I want to really take the stress out of making dinner, I turn to sous vide. That may seem strange to you if sous vide cooking is a culinary technique that you’re not very familiar with, but when you can prepare dinner very early on in the day and you take all the necessary precautions to ensure success, any stress you might have about preparing dinner just vanishes.

 

Sous vide cooking is when you place food in a vacuum-sealed bag and submerge that bag completely in a water bath which is held at a very precise temperature for a prescribed period of time – usually a temperature much lower and a time much longer than you think. When you cook food at a very precise temperature, you end up with really precise results and the food really cannot over-cook. When the food cooks at a lower temperature and a little more slowly than on a stovetop or in the oven, you have more flexibility on timing and can relax a little, knowing that you won’t make a last minute mistake. With meats cooked sous vide you can expect perfect, juicy, tender and flavorful results. See? You really can take the stress out of making dinner.

 

The only precautions you really have to take to ensure success with sous vide is 1) make sure you leave enough time to cook the food properly and 2) make sure the food is properly sealed in a bag and that all the air has been removed so that the bag sinks completely in the water bath. The first precaution is relatively easy to manage – just plan ahead. The second precaution of making sure the bag of food is sealed properly and that the air has been removed can be achieved if you use the right sous vide bag and the best technique for removing air from that bag. FoodSaver® Bags really do take away any worry you might have about the bags and vacuum sealing because they are BPA-free and can handle the temperature of sous vide water baths, they seal effectively and are air-tight. An air-tight bag is so important for sous vide cooking because it creates better heat transmission from the water to the food and gives you more even and consistent results. If you’re using the right sous vide bag and vacuum sealing with a FoodSaver® Preservation System, you can put your mind at ease and just enjoy the process. Plus, because of their high quality, you can wash and re-use your FoodSaver® Bags thereby creating less waste.

This recipe for Korean BBQ Pork Loin uses one of my favorite ingredients – Gochujang. It’s a Korean BBQ chili paste that has become quite popular lately and can be found at many grocery stores or specialty Asian markets. All the other ingredients for the marinade as well as for the Korean BBQ sauce are very common and can be found at every grocery store.

Vacuum-sealing the pork along with the marinade in a FoodSaver® bag helps to infuse all those flavors into the pork and lets the pork and the marinade flavors really fuse together over time. It’s also extremely tidy and easy to work with all the ingredients together in a bag and I value tidiness in the kitchen next to… well, you know where I’m going. You can even freeze the pork with the marinade at this stage and cook it later – just add another 90 minutes to the cooking time. The FoodSaver® Bag can go directly from the freezer to the sous vide water bath without any trouble.

Once you’ve let the pork sink in the water bath, you now have 4 to 6 hours to wait… or do whatever it is you do. The only recipe requirement in that time is to make the BBQ sauce, which is super easy to put together by sautéing a little onion, garlic and ginger, adding the rest of the ingredients and simmering for 20 minutes or so.

The final step in this recipe just requires a quick broil on all sides of the perfectly-cooked pork loin with some of the delicious spicy-sweet BBQ sauce brushed on. Just remember to only broil for a couple of minutes per side so that you don’t overcook the pork that you’ve prepared so perfectly.

All you’ll have left to do is slice and serve. This pork is delicious with some white rice, a quick-sautéed green vegetable (like bok choy) and garnished with a few chopped scallions. Easy, stress free and delicious!

Sous Vide Korean BBQ Pork Loin

  • Prep Time: 15 m
  • Cook Time: 4 h
  • Total Time: 4 h 15 m
  • Servings:
    6

Ingredients

  • ¼ cup gochujang chili paste
  • 3 tablespoons honey
  • ¼ cup soy sauce
  • 2 tablespoons toasted sesame oil
  • 3 cloves garlic minced
  • 2 tablespoons fresh ginger minced
  • 1 (3-pound) pork loin roast
Korean BBQ Sauce:
  • 1 teaspoon olive oil
  • ¼ onion finely chopped
  • 1 teaspoon minced garlic
  • 1 teaspoon minced ginger
  • 3 tablespoons tomato paste
  • 2 tablespoons brown sugar
  • 1 tablespoon gochujang chili paste
  • ¼ cup apple cider vinegar
  • 2 tablespoons soy sauce
  • 1 tablespoon sesame oil
  • chopped scallions for garnish

Instructions

  1. Pre-heat the sous vide water bath to 144°F.
  2. Combine the gochujang, honey, soy sauce, sesame oil, garlic and ginger in a bowl. Pierce the pork loin several times with a sharp paring knife and then place it in a FoodSaver® Bag. Pour the marinade on top and massage the marinade into the pork to coat it well. Vacuum seal the bag using the FoodSaver® vacuum sealer to remove all the air. This will ensure that the food will sink in the water bath and be completely submerged.

  3. Place the pork into the sous vide water bath and cook at 144ºF for at least 4 hours or for as long as 6 hours.
  4. While the pork is cooking, make the Korean BBQ sauce. Heat the olive oil in a medium sauce pan. Add the onion and sauté for a minute or two. Add the garlic and ginger and sauté for another minute. Add the tomato paste, brown sugar, gochujang, apple cider vinegar, soy sauce and sesame oil and bring the mixture to a boil. Lower the heat and simmer for 20 minutes until the sauce thickens.
  5. Remove the pork from the sous vide water bath, open the bag and place the pork loin on a baking sheet. Discard the juices.
  6. Pre-heat the broiler. Brush the Korean BBQ sauce onto all sides of the pork loin and broil for two minutes on each side, turning and brushing the pork with more BBQ sauce as you broil. Alternatively, you can grill the pork on a very hot grill or in a very hot grill pan for 1 to 2 minutes on each side, basting with BBQ sauce. Either way, avoid broiling or gilling the pork for too long, so that you don’t overcook it.
  7. Transfer the pork loin to a cutting board, cover with foil and let it rest for a few minutes.
  8. Slice the pork loin and transfer slices to serving platter. Garnish with chopped scallions and serve with the with any remaining BBQ sauce on the side.
