Ingredients for boneless pork loin centre cut roast
Precision-cut pork loin, expert seasonings, and a two-stage sear unlock restaurant-quality tenderness at home.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless Pork Loin Centre Cut 🥩 | 3 lb | Even thickness, 1.5-inch minimum |
| Kosher Salt 🧂 | 1 ½ tbsp | Diamond Crystal preferred, coarse grain |
| Freshly Ground Black Pepper 🌶️ | 1 tsp | Cracked peppercorns preferred |
| Unsalted Butter 🧈 | ½ cup | Cold, cut into 1-inch cubes |
| Fresh Rosemary Sprigs 🌿 | 4 whole | Thick stems, leaves intact |
| Fresh Thyme Sprigs 🌿 | 4 whole | Leaves only, stems removed |
| Garlic Cloves 🧄 | 8 cloves | Smashed, peel intact |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | Light fruity variety |
| Red Wine Vinegar 🍷 | 1 tbsp | Dry, 12% acidity minimum |
| Granulated Garlic 🧄 | 1 tsp | For dry brine |
| Dried Mustard Powder 🌶️ | ½ tsp | For depth of flavor |
| Fresh Parsley Sprigs 🌿 | 2 whole | For garnish |
The centre-cut pork loin is non-negotiable for this recipe—look for a uniform 1.5-inch thickness or thicker to ensure even cooking. Whole Foods and D'Artagnan carry premium centre-cut loins, but most high-end grocery stores stock them. If buying whole, trim the silver skin carefully—it can interfere with the sear. For the dry brine, use Diamond Crystal kosher salt (it's coarser than Morton) to enhance moisture retention without over-salting. The garlic should be freshly smashed to release maximum flavor, not minced—this ensures it infuses the butter during searing rather than burning.
No fresh rosemary? Substitute 1 tbsp dried rosemary, but reduce to half the amount—dried herbs are more concentrated. Short on time? Pre-mix the dry brine ingredients in a small jar for future use. The olive oil should be light fruity (like California Extra Virgin from Trader Joe's) to complement the pork without overpowering. For the wine vinegar, avoid balsamic—its sweetness can clash with the sear. The butter must be cold and cubed when searing; if it melts prematurely, reduce oven temperature by 25°F and increase searing time by 2 minutes per side. The mustard powder adds subtle complexity—substitute 1 tsp Dijon mustard if preferred.
The pork loin should rest 15 minutes before slicing—this critical step ensures juices redistribute. Store leftovers in an airtight container for 3 days in the fridge or 3 months frozen. For reheating, use low heat to prevent drying—microwave on 50% power for 1-2 minutes or warm in a 250°F oven for 10 minutes. The herb butter can be made ahead and stored in the fridge for 1 week—perfect for slicing onto finished pork. If prepping for a crowd, scale the recipe up proportionally, but never exceed a 3-pound roast for even cooking in a standard home oven.

Step-by-step instructions for boneless pork loin centre cut roast
Master this technique for a perfectly tender centre-cut roast with a clockwork sear.
Prepare the Dry Brine for Maximum Tenderness
Remove the boneless pork loin centre cut from packaging and pat it completely dry with paper towels. This step is critical—any moisture will prevent that perfect crispy crust. Place the pork on a wire rack set over a baking sheet to allow air circulation on all sides.
In a small bowl, combine the 1.5 tbsp kosher salt, 1 tsp freshly ground black pepper, 1 tsp granulated garlic, and 0.5 tsp dried mustard powder. Rub this mixture evenly over all surfaces of the pork, pressing gently to ensure the seasoning adheres. The mustard powder adds subtle depth while the garlic enhances natural pork flavors.
Cover the pork loosely with plastic wrap and refrigerate for 12-24 hours. This dry brine transforms the meat by breaking down proteins and allowing the seasoning to penetrate deeply. Real talk: Don't skip this step. The texture difference is night and day compared to dry-brining for just a few hours.
Create the Herb Butter and Sear the Pork
Remove the pork from the refrigerator 1 hour before cooking to bring it to room temperature. This ensures even cooking throughout. In a small bowl, combine the 0.5 cup cold unsalted butter, 4 whole fresh rosemary sprigs, 4 whole fresh thyme sprigs, and 8 smashed garlic cloves. Mix well and shape into a log, then wrap in plastic wrap and refrigerate until ready to use.
Preheat your oven to 425°F. Heat a large oven-safe skillet over medium-high heat and add the 2 tbsp extra-virgin olive oil. Once shimmering, carefully place the pork loin in the skillet, fat-side down. Sear for 4-5 minutes until a deep golden brown crust forms. Flip the pork and add the herb butter to the skillet, tilting to coat the bottom.
Here's the thing—this initial sear creates the foundation for that coveted clockwork crust. You'll know it's ready when the pork releases easily from the skillet and the butter begins to foam. Don't rush this step; patience here prevents a pale, soggy exterior.
Roast to Perfect Doneness
Transfer the skillet to the preheated oven and roast for 20-25 minutes. The pork should reach an internal temperature of 140°F at this point. Remove from the oven and let it rest for 10 minutes before checking the temperature again—it will rise to 145°F during resting, which is ideal for juicy, tender pork.
While the pork rests, prepare a quick pan sauce by deglazing the skillet with the 1 tbsp red wine vinegar. Scrape up all the browned bits with a wooden spoon, then remove from heat. The vinegar cuts through the richness of the butter while adding brightness to complement the herb flavors.
Rest and Slice for Maximum Juiciness
After the 10-minute rest, carefully transfer the pork to a cutting board. The resting period is crucial—it allows the juices to redistribute throughout the meat. If you slice too soon, all those precious juices will pool on your plate instead of staying in the pork.
Slice the pork against the grain into ½-inch thick slices. The grain runs lengthwise, so cutting perpendicular gives you tender, bite-sized pieces. Arrange the slices on a warm platter and drizzle with the pan sauce. Garnish with the 2 whole fresh parsley sprigs for a pop of color and freshness.
Serve immediately with roasted vegetables or a simple green salad. Each slice should be fork-tender with a crispy exterior and juicy interior. The herb butter infuses every bite with aromatic rosemary, thyme, and garlic, while the dry brine ensures perfect seasoning throughout.
Pro Tips For Making Boneless Pork Loin Centre Cut Roast
- USE A MEAT THERMOMETER: I learned this the hard way—pork loin looks done long before it actually is. Aim for 145°F (63°C) internal temp, then let it rest. No guessing, no dry meat.
- SALT THE PORK 24 HOURS EARLY: More salt than you think, especially if using unsalted butter. Sprinkle generously on all sides, then refrigerate uncovered for a full day—this seasoning actually gets into the meat.
- SEAR IN BATCHES TO AVOID STEAMING: High heat, but don’t crowd the pan. Brown the pork in 2-3 batches to get that crust, or you’ll end up with sad, pale meat. A hot pan is non-negotiable here.
- REST UNDER FOIL, NOT PLATES: Give it a solid 5-10 minutes under foil after roasting—this keeps it juicy. I know, I know, but trust the process. Your knife will thank you.
Storing and reheating this boneless pork loin centre cut roast
Refrigerator Storage
Store your sliced pork loin in an airtight container with a damp paper towel to retain moisture. It'll keep for 3 days in the fridge at 40°F or below—just reheat gently to avoid drying out.
I always portion mine into single-serving containers for easy grab-and-go lunches. The herb butter flavor actually intensifies overnight, making leftovers taste even better. 💫
Freezer Prep
For longer storage, wrap individual slices tightly in plastic wrap before placing them in a freezer bag with all air removed. This prevents freezer burn and preserves texture for up to 3 months.
When ready to eat, thaw overnight in the fridge—never at room temperature—to maintain food safety. I've found that freezing works best with the herb butter still attached to the slices. ❄️
Reheating Methods
For the best results, reheat in a skillet over medium-low heat with a splash of water or broth to prevent drying. Cover and cook for 3-5 minutes until reaching 165°F internal temperature.
Microwaving works in a pinch—use 50% power for 1-2 minutes with a damp paper towel covering. The oven method at 250°F for 10 minutes gives the most even heating without overcooking. 🔥
Reviving Texture
If your reheated pork feels dry, brush it with a little olive oil and warm it for another 1-2 minutes—this reactivates the crust. For extra moisture, add a small pat of herb butter while reheating.
I've even revived slightly overcooked pork this way at family gatherings. The key is low heat and patience—never rush the process. 💡
Make-Ahead Tips
Prep the dry brine and herb butter 2 days ahead to streamline cooking day. Store the seasoned pork in the fridge until ready to sear, and keep the herb butter mixture refrigerated in its log form.
This saves 30 minutes of prep work on busy days. I always do this when hosting dinner parties—it cuts down on last-minute stress. 📅
Serving Leftovers
Transform leftover pork into pork fried rice, sandwiches, or pasta dishes for easy lunches. The tender slices hold up well in these recipes. For a quick fix, toss with store-bought stir-fry sauce and serve over rice.
I've even made pork empanadas with these leftovers—just add some cheese and you're golden. 🌟

Frequently asked questions
Why is the centre cut so important for this roast?
The centre cut delivers the most tender, flavorful meat because it comes from the middle of the loin where the muscle fibers are less developed. Unlike shoulder cuts, it stays juicy without becoming tough. For this recipe, look for a uniform 1.5-inch thickness or thicker to ensure even cooking throughout.
Can I use a bone-in pork loin instead?
Technically yes, but the cooking time and method will differ. Bone-in loins require 15-20 minutes longer to reach the same internal temperature due to the bone's insulating effect. You'll need to adjust the oven time and monitor closely to prevent overcooking the exterior while the center cooks.
What's the best way to check doneness without a thermometer?
Press the thickest part of the pork with your finger—it should feel soft but still slightly springy, like pressing your thumb into the fleshy part of your forearm. The juices should run clear when pierced with a knife. For extra confidence, cut into a small test slice to check the color and texture before serving.
How do I adjust this recipe for a larger crowd?
Scale the recipe proportionally, but never exceed a 3-pound roast in a standard home oven for even cooking. For larger quantities, divide into 2-pound portions and roast separately. Increase oven capacity by using multiple skillets or a larger roasting pan. The dry brine time remains the same per pound of meat.
What if my pork loin comes out dry?
Overcooking is the most common cause. Always aim for 145°F internal temperature and let it rest 15 minutes before slicing. If it's slightly undercooked, return to a 275°F oven for 5-10 minutes to carry over cook. For prevention, never skip the dry brine or resting steps—these are critical for moisture retention.
