Say goodbye to tough and flavorless pork loin! My kids never liked pork until I discovered the sous vide method.

What’s sous vide? Sous vide is a French cooking technique where the food is vacuum-sealed in a bag, and then cooked for a long time to a precise temperature in a warm water bath. It’s a foolproof way to get the perfect doneness.

Pork Loin vs. Pork Tenderloin

Pork loin and pork tenderloin are two different cuts of meat. Pork loin is wider and thicker, and comes from the back of the animal. It can be bone-in or boneless. While pork tenderloin is a long, narrow, and boneless cut that runs along the backbone.  

Ingredients You’ll Need

• Pork Loin Roast: Choose the right size pork loin for this recipe. If you don’t have a vacuum sealer and have to use a zip-loc bag, you’ll need to buy a smaller pork loin that can fit into the bag. Alternatively, you can cut the roast into two pieces to accommodate the bag.
• Garlic Powder: Adds complexity and deep rich flavor to this dish.
• Paprika: It adds a beautiful color and sweet peppery flavor to the dish. I used regular paprika, but you can use smoked paprika for a smoky flavor.
• Salt: I used kosher salt, but you can use table salt or sea salt.
• Pepper: Freshly ground black pepper works the best.
• Optional herbs: I used fresh rosemary sprigs. Thyme also works well.
• Olive Oil: It helps caramelize the surface of the pork loin in the skillet after sous vide cooking.

How to Sous Vide Pork Loin Roast

1. Pre-heat sous vide machine: Set the Sous Vide Precision Cooker to 140°F (60°C).  

2. Make the dry rub seasoning: Mix together garlic powder, paprika, salt, and pepper.

3. Season pork loin: Rub the pork loin with the seasoning.

4. Vacuum-seal the meat: Place the seasoned roast in a zip-lock bag (or vacuum-sealer). Seal the bag using the water displacement technique.

5. Sous vide cook pork loin: Place the bag in the sous vide warm water bath and cook for 3 hours. When the timer goes off, remove the bag from the water.

6. To finish: Remove the roast from the bag and pat dry with paper towels. Sear for about 1-2 minutes per side, just to caramelize the outside. Add more seasoning if needed. Slice against the grain and serve.

Sous Vide Pork Loin Seasoning

The dry rub helps to boost flavor and tenderize pork loin. I like this simple seasoning made with just a few ingredients you already have at home. You don’t need to brine it.

It’s important to season your roast generously BEFORE cooking it in the sous vide machine.

Sous Vide Pork Loin Temperature

I like my pork loin medium, so I set the sous vide machine to 140°F/60°C. If you’d like to try another doneness, follow the chart below:

Pork Loin Doneness	Temperature	Texture
Medium Rare	130°F	Buttery tender and very juicy
Medium	140°F	Tender and very juicy
Medium Well	150°F	Firm and moderately juicy
Well Done	160°F	Firm and slightly dry

Frequently Asked Question

How Long Does it Take to Sous Vide Pork Loin Roast?

There is a wide range of cooking time, my pork loin is about 3 pounds, and I find cooking it at 140°F/60°C for 3-4 hours gives me the best result.

• If you cook it for 8 hours, it will become softer, but can be dry with less flavor.
• 3-4 hours make it very tender and juicy.
• If your roast is larger, you may need to increase cooking time.

Can You Overcook Pork Loin in the Sous Vide machine?

Although you cannot “overcook” pork meat with the sous vide method (you can leave the meat in a warm bath for an extra hour or two), the texture can become mushy if the roast is left in the machine for too long.

Can You Eat Pork at 140 F Degrees?

According to USDA, pork can be consumed safely when cooked to an internal temperature of 145 F degrees. This guide is for the traditional cooking methods, but pasteurization is based on both temp and time at that temp. So sous vide pork at 140 F degrees is safe to eat after the long cooking time.

How to Seal the Bag Without a Vacuum Sealer?

For this recipe, if your pork loin is not too big, you can use a Ziploc Freezer Bags. The trick is called the “water displacement method” by using the pressure from the water to force all the air out of the bag. 

Just place your food in the bag, seal all but one corner of the bag. Slowly place it in the water bath, and make sure everything below the zip-line is covered by water. Then seal the rest of the bag.
