Sous vide cooking is a fantastic method for preparing pork loin, as it allows you to achieve perfectly tender and juicy meat. Here's a simple recipe for sous vide pork loin that you can follow:
Sous Vide Pork Loin Recipe
Ingredients:
2 to 3 pounds pork loin
Salt (to taste)
Black pepper (to taste)
Fresh herbs (e.g., thyme, rosemary, or sage)
2-3 cloves garlic, minced (optional)
Olive oil or butter (for searing)
Equipment:
Sous vide immersion circulator
Large pot or sous vide container
Vacuum sealer or resealable ziplock bags
Skillet (for searing)
Instructions:

Prepare the Sous Vide Water Bath:

Fill a pot or sous vide container with water and attach your immersion circulator. Set the temperature to your desired doneness:
Medium Rare: 140°F (60°C) for 1.5 to 4 hours
Medium: 145°F (63°C) for 1.5 to 4 hours
Medium Well: 150°F (65°C) for 1.5 to 4 hours

Season the Pork Loin:

Pat the pork loin dry with paper towels. Season generously with salt and black pepper. If desired, add minced garlic and fresh herbs on top of the meat.

Vacuum Seal the Pork:

Place the seasoned pork loin in a vacuum-seal bag or a resealable ziplock bag. If using a ziplock bag, use the water displacement method to remove as much air as possible: seal the bag almost completely, then slowly submerge it in water, allowing the pressure to push out the air before sealing the bag fully.

Sous Vide the Pork Loin:

Submerge the sealed bag in the preheated water bath. Cook for the desired time (at least 1.5 hours, up to 4 hours).

Finish the Pork Loin:

Once the cooking time is complete, remove the bag from the water bath. Carefully take the pork loin out of the bag and pat it dry with paper towels (this helps achieve a good sear).
Heat a skillet over medium-high heat and add a little olive oil or butter. When hot, sear the pork loin for about 1-2 minutes on each side until golden brown. This step adds flavor and texture.

Rest and Serve:

Let the pork rest for a few minutes before slicing it. Serve with your favorite sides, such as roasted vegetables, mashed potatoes, or a fresh salad.
Tips:
You can add other seasonings or marinades according to your taste. Mustard, soy sauce, or a spice rub can work well.
Cooking times can be adjusted depending on the thickness of the pork loin; thicker cuts may need a bit longer.
Use a meat thermometer to check doneness after searing if you're unsure.
Enjoy your perfectly cooked sous vide pork loin!
