Ingredients for boneless pork loin roast recipe sous vide
Precision ingredients for restaurant-quality pork loin that stays juicy and tender every time.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless Pork Loin Roast 🥩 | 2 lb | Center-cut, 1.5-inch thick |
| Kosher Salt 🧂 | 1 ½ tbsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | 1 tsp | Cracked peppercorns preferred |
| Garlic Cloves 🧄 | 6 cloves | Smashed, skin-on |
| Fresh Rosemary 🌿 | ½ cup | Chopped sprigs, not dried |
| Fresh Thyme 🌿 | ¼ cup | Leaves only, stems removed |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | For searing, high smoke point |
| Vegetable Oil 🫒 | ½ cup | For vacuum bag lining |
| Water 💧 | 2 cups | For vacuum bag ice bath |
| Dry White Wine 🍷 | ½ cup | Sauvignon Blanc preferred |

The pork loin cut matters—center-cut, 1.5-inch thick slices beautifully and cooks evenly. Costco or Whole Foods carry excellent boneless pork loins, but check for good marbling. If buying whole, trim excess fat and score the surface lightly for even seasoning. Fresh herbs are non-negotiable here—their bright flavors cut through the richness of the pork. I always grab organic rosemary and thyme from the grocery store's produce section, but if you're short on time, dried works at half the amount (though fresh is worth the extra minute).
No white wine? Substitute with extra vegetable broth—just add a splash of lemon juice for brightness. The olive oil for searing needs to have a high smoke point; Avocado oil works if you're worried about burning. For the vacuum bag, I use FoodSaver brand bags—they seal better than the generic ones. If you don't have a vacuum sealer, the water displacement method (freezing ice cubes in a bag with your meat) works in a pinch. The butter for searing should be cold—pull it from the fridge 10 minutes before cooking—to create that perfect crust.
Sous vide pork holds for 3 days refrigerated before searing, but it's best eaten fresh. If storing, keep it in the vacuum bag submerged in water to maintain moisture. Once seared, it reheats beautifully—200°F for 10-15 minutes in the oven. I portion mine into 1/4-inch slices for easy serving. The wine reduction left in the bag? Save it for drizzling over the final dish—it's pure flavor gold.
Why You'll Love This Recipe

- Budget-Friendly Luxury: Pork loin is cheaper than steak but feels just as fancy when you nail the technique. A single roast feeds my family for three meals, and the ingredients? Salt, pepper, garlic, rosemary—stuff I already have. Fancy dinner, zero guilt.
Step-by-step instructions for sous vide pork loin roast
Mastering sous vide transforms tough pork into melt-in-your-mouth perfection—here's exactly how to do it right.
Prepare and Season the Pork Loin
Begin by patting the 2 lb boneless pork loin roast completely dry with paper towels. This step is crucial because moisture on the surface prevents proper vacuum sealing and can lead to uneven cooking. Place the roast on a plate and generously rub with the 1.5 tbsp kosher salt and 1 tsp freshly ground black pepper, pressing the seasoning into the meat so it adheres evenly.
Next, create your herb mixture by finely chopping the 6 smashed garlic cloves, 0.5 cup fresh rosemary, and 0.25 cup fresh thyme leaves. Rub this aromatic blend all over the pork, making sure to get it into any crevices. Let the seasoned roast sit at room temperature for 30 minutes while you prepare the vacuum bag setup. This resting period allows the seasonings to penetrate the meat and ensures even cooking throughout.
Set Up the Sous Vide Bath
Fill a large stockpot or sous vide container with 2 cups water and place it on a burner set to maintain a precise 145°F temperature. I use a thermometer to verify the water temperature before adding the pork—this is the magic number for achieving perfectly tender pork without drying it out. Let the water come to temperature and stabilize for at least 10 minutes before proceeding.
While the water heats, prepare your vacuum bag by lining it with a layer of 0.5 cup vegetable oil. This oil creates a protective barrier that prevents the pork from drying out during the long cook. Place the seasoned pork loin into the bag, seal it completely, and submerge it in the water bath. The bag should float freely—if it sinks, it's not properly sealed.
Cook to Precision Tenderness
Cook the pork in the 145°F bath for 24 hours. This extended time at a precise temperature guarantees the meat will be fork-tender without any risk of overcooking. I place a weight on the bag to keep it fully submerged, which helps maintain consistent temperature throughout the cook. Resist the urge to open the bag or check the progress—every interruption can affect the cooking process.
After 24 hours, remove the pork from the bag and pat it dry with fresh paper towels. This step is important because any residual moisture will prevent the butter sear from sticking properly. Let the pork rest at room temperature for 15 minutes before proceeding to the sear—this brief rest allows the surface to dry slightly, creating the perfect canvas for that golden crust.
Create the Perfect Butter Sear
Heat a large skillet over medium-high heat until it's very hot but not smoking. Add the 4 tbsp cold cubed unsalted butter and let it melt completely, then add the 0.25 cup extra-virgin olive oil. Swirl the pan to coat it evenly with the butter-oil mixture—this combination creates a rich, flavorful sear without burning.
Carefully place the pork loin in the skillet and sear for 2-3 minutes per side until it develops a deep golden-brown crust. You'll know it's ready when the surface is caramelized and the pork releases easily from the pan. Remove the pork and let it rest for 10 minutes before slicing—this resting period allows the juices to redistribute, ensuring each slice is moist and flavorful.
Prepare the Wine Reduction Sauce
In the same skillet (don't wipe it clean—the browned bits are pure flavor), pour in the 0.5 cup dry white wine and scrape up all the caramelized fond from the bottom of the pan. Let the wine reduce by half over medium heat until it reaches a syrupy consistency. This reduction captures all the flavors from the sear and creates a glossy sauce that complements the pork beautifully.
Remove the skillet from heat and stir in the 0.25 cup vegetable broth. Taste and adjust the seasoning with additional salt and pepper if needed. The sauce should be rich, slightly tangy, and perfectly balanced. Serve the pork sliced into ½-inch thick pieces alongside the wine reduction sauce for a restaurant-quality meal at home.
Pro Tips For Making Boneless Pork Loin Roast Recipe Sous Vide
- Trim the Fat Cap: Pork loin can look deceptively lean, but those thin fat strips along the edges render fast—so snip them off before sealing. I learned this after my first batch turned greasy in the bag; now I use kitchen shears for clean cuts and a paper towel to wipe excess moisture from the surface.
- Use Whole Garlic: Skip the minced—toss 2-3 whole garlic cloves (peeled, smashed) with the rosemary into the bag. The sous vide heat will soften them into a fragrant paste that clings to the meat, saving you from prepping ahead. (Yes, even if you’re impatient like me.)
- Don’t Rush the Chill: Pull the pork from the fridge at least 30 minutes before vacuum-sealing—cold meat cooks unevenly and risks tearing the bag. I was skeptical until I tried it: the texture is silky instead of tough, and the seasoning sticks better. (Your future self will notice.)
- Sear After, Not Before: Sous vide does the heavy lifting, but a post-bath sear in a screaming-hot pan with butter and cracked pepper is where the magic happens. The crust locks in juices—just 30 seconds per side, or you’ll burn the rosemary. (This isn’t the prettiest method, but it’s the tastiest.)
Make-ahead tips for this recipe
Prep Ahead
Season and vacuum-seal your pork loin up to 2 days in advance—I store mine in the fridge in a sealed bag with a damp paper towel to prevent drying. The herbs and garlic will infuse beautifully overnight, giving you more time to focus on the sous vide setup. Just
Sous Vide Timing
Cook your pork loin for the full 24 hours—this is non-negotiable for perfect tenderness. I often set my sous vide machine to run overnight while I sleep, waking up to perfectly cooked meat. If you're short on time, 12 hours will work in a pinch, but the texture won't be quite as luxurious. The longer cook time is worth it for special occasions.
Storage Solutions
After cooking, store the vacuum-sealed pork in its bag submerged in cold water in the fridge for up to 3 days. This keeps it moist and ready for a quick sear whenever you're ready to serve.
I like to portion the wine reduction separately in a small container—it keeps well for 2 days and adds instant flavor when reheated. For longer storage, freeze the pork in its vacuum bag for up to 3 months.
Reheating Tips
If you've stored your sous vide pork, reheat it gently to preserve moisture. Place the bag in a 160°F water bath for 30-45 minutes until warmed through. For a quick sear, pat it dry and finish in a hot pan with butter and oil.
Never microwave—it turns the meat rubbery. The wine reduction reheats beautifully in a small saucepan over low heat for 2-3 minutes.
Make-Ahead Sides
Prep sides the day before to streamline serving. Roasted vegetables or mashed potatoes can be made ahead and reheated in the oven while the pork sears. I also like to make a simple herbed couscous or wild rice pilaf—both pair perfectly and reheat well.
Keep sauces and dressings separate until serving to maintain freshness. This way, you only need to focus on the final sear and plating. 🌟

Frequently asked questions
Can I use a thinner or thicker pork loin cut?
The ideal thickness is 1.5 inches—this ensures even cooking and perfect doneness throughout. For thinner cuts (1 inch), reduce sous vide time to 18 hours to avoid overcooking. Thicker cuts (>2 inches) may need 28 hours but risk uneven texture. Always measure thickness before cooking to adjust timing accordingly.
What if I don't have a vacuum sealer?
No problem! Use the water displacement method: place the seasoned pork in a zip-top bag, add ice cubes, seal it halfway, then submerge in cold water. The ice melts, creating a vacuum as the bag seals completely. This works just as well for 24-hour sous vide cooking—just ensure the bag is fully submerged in the water bath.
Why does the pork need 24 hours? Can I speed it up?
The 24-hour cook at 145°F breaks down connective tissue for restaurant-style tenderness. While 12 hours works in a pinch, it won't be as luxurious. For special occasions, never rush it—the extra time transforms tough meat into melt-in-your-mouth perfection. Think of it as overnight brining for pork!
How do I store leftovers without drying out?
Keep cooked pork in its vacuum bag submerged in cold water for 3 days in the fridge. For longer storage, freeze the bagged pork for up to 3 months. To reheat, use a 160°F water bath for 30-45 minutes—never microwave! The wine reduction can be refrigerated separately for 2 days or frozen for 1 month.
What's the best way to slice for serving?
Slice against the grain at a 45-degree angle for elegant presentation and maximum tenderness. Use a sharp knife and cut into ½-inch thick slices. For family-style serving, arrange slices fan-style on a platter with the wine reduction drizzled artfully around them. The crusty edges add visual appeal!
