A 10 lb pork loin recipe transforms any gathering into a showstopping centerpiece—crisp golden crust, tender pink core, and enough leftovers for sandwiches the next day. I've cooked thousands of pounds of pork in my time at The Smoky Pig, and this method delivers restaurant-quality results at home.
The secret lies in precise temperature control and a simple dry brine that keeps the meat juicy from edge to edge.
We'll start with a dry brine—just salt and pepper applied generously 24 hours ahead—that penetrates deeply for maximum flavor and moisture retention. Cooking at 325°F ensures even heat distribution, creating that perfect crust while maintaining a juicy interior.
This isn't just a recipe; it's a technique that's earned me multiple BBQ championships, and I'm sharing it with you.
The result? A pork loin with a crackling crust that shatters at the first cut, revealing tender meat that's just pink in the center—never dry, never overcooked. The aromas alone will have guests gathering before the table's even set.
Serve with pan juices reduced into a glossy glaze, or pair it with classic Southern sides like creamy mac and cheese or roasted sweet potatoes.
This recipe scales beautifully—use the same method for smaller loins by adjusting cooking time proportionally. The dry brine technique works equally well for pork tenderloins or even whole hams. Let's get started on creating your next centerpiece dish.
Ingredients for 10 lb pork loin
Restaurant-quality pork loin starts with these carefully selected ingredients for a showstopping centerpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Bone-In Pork Loin 🐖 | 10 lb | Center-cut, 2-inch thick |
| Kosher Salt 🧂 | ½ cup | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | 2 tbsp | Coarse grind for texture |
| Unsalted Butter 🧈 | ¼ cup | Cold, cubed for basting |
| Yellow Onion 🧅 | 1 whole | Thinly sliced for glaze |
| Garlic Cloves 🧄 | 8 cloves | Minced for aromatics |
| Apple Cider Vinegar 🍎 | ¼ cup | For glaze acidity |
| Brown Sugar 🍚 | ½ cup | Packed for glaze depth |
| Smoked Paprika 🌶️ | 1 tbsp | For glaze color |
| Fresh Rosemary 🌿 | ¼ cup | Chopped for aroma |
| Fresh Thyme 🌿 | ¼ cup | Leaves only for flavor |
| Vegetable Oil 🫒 | ½ cup | High smoke point for sear |
The pork loin's quality is non-negotiable for this recipe. Look for bone-in center cuts from a trusted butcher—The Smoky Pig's preferred suppliers include local farms with grass-fed options. A 2-inch thickness ensures even cooking and maximum crust development. For the dry brine, Diamond Crystal kosher salt dissolves more easily than table salt, creating superior moisture retention throughout the meat. Freshly ground black pepper adds texture without overpowering the pork's natural flavor. If you can't source a 10 lb loin, two 5 lb loins work perfectly with adjusted cooking times.
No Diamond Crystal salt? Morton kosher salt is a direct substitute, though use slightly more due to its coarser grind. Fresh herbs wilt during cooking, so dried rosemary and thyme at one-third the amount work in a pinch. For the glaze, honey can replace brown sugar for a different flavor profile, though it requires less liquid. The apple cider vinegar adds brightness—white wine vinegar works equally well. When basting, use clarified butter for a cleaner finish, though regular butter adds richness. Prefer a smokier glaze? Add 1/2 tsp smoked salt to the glaze mixture.
The pork loin should rest uncovered at room temperature for 1 hour before cooking to ensure even heat penetration. Store any unused herbs in damp paper towels wrapped in plastic for up to 5 days. The dry brine can be applied 24 hours ahead, making this a perfect make-ahead recipe. Leftover pork keeps 3-4 days refrigerated or 3 months frozen. For best results, slice against the grain and serve with reduced pan juices for a restaurant-quality presentation.

Step-by-step instructions for 10 lb pork loin with crispy crust
Master this technique and you'll achieve a perfect balance of juicy pink center and caramelized exterior every time.
Prepare and Season the Pork Loin
Remove the pork loin from the refrigerator and pat it completely dry with paper towels. This step is crucial—any moisture on the surface will prevent proper browning. Place the loin on a wire rack set over a baking sheet to allow air circulation on all sides.
In a small bowl, combine the 0.5 cup kosher salt and 2 tablespoons freshly ground black pepper. Using your hands, rub this mixture all over the pork loin, pressing firmly so the seasoning adheres to the surface. Pay special attention to the fat cap and any crevices. Let the seasoned pork loin sit at room temperature for 30 minutes while you prepare the remaining ingredients. This resting period ensures even cooking throughout.
Create the Glaze and Herb Butter
In a medium saucepan, combine the 0.5 cup brown sugar, 0.25 cup apple cider vinegar, 1 tablespoon smoked paprika, 1 whole yellow onion (thinly sliced), and 8 cloves garlic (minced). Bring the mixture to a simmer over medium heat and cook for 10 minutes until the onions soften and the liquid reduces by half. This creates a thick, flavorful glaze that will caramelize beautifully on the pork.
In a separate bowl, mix the 0.25 cup unsalted butter with 0.25 cup chopped fresh rosemary and 0.25 cup fresh thyme leaves. This herb butter will baste the pork during cooking, infusing it with aromatic flavors while keeping it moist. Keep both the glaze and herb butter at room temperature until ready to use.
Sear the Pork Loin for Maximum Flavor
Preheat your oven to 375°F. Heat 0.5 cup vegetable oil in a large oven-safe skillet over medium-high heat until shimmering. Carefully place the pork loin in the skillet, fat side down, and sear for 8-10 minutes until the fat renders and the exterior develops a deep golden brown crust. Flip the pork and sear the other side for an additional 6-8 minutes. This high-heat sear locks in juices and creates the foundational crust.
During the last 2 minutes of searing, brush the pork with half of the herb butter. Transfer the skillet to the preheated oven and roast the pork for 30-40 minutes, basting with the remaining herb butter every 10 minutes. The internal temperature should reach 140°F at this point, leaving the center slightly pink and juicy.
Apply the Glaze and Finish
Remove the pork loin from the oven and increase the heat to 425°F. Brush the entire surface of the pork with the prepared glaze, working quickly so it doesn't cool. Return the skillet to the oven and broil for 5-7 minutes, watching closely to prevent burning. You'll know it's done when the glaze caramelizes to a deep amber color and forms a glossy crust.
The pork is perfectly cooked when the internal temperature reaches 145°F and a meat thermometer inserted into the thickest part of the loin (without touching bone) reads consistently. Let the pork rest for 15-20 minutes before slicing—this resting period allows the juices to redistribute, ensuring each slice remains moist and flavorful.
Pro Tips For Making 10 Lb Pork Loin
- USE A MEAT THERMOMETER: I learned this the hard way—guessing pork doneness with a knife. For a 10 lb bone-in loin, aim for 145°F internal temp (155°F if serving kids/pickier eaters). The bone conducts heat unevenly, so check the thickest part of the muscle, not near the bone. A cheap $15 thermometer beats slicing into a $60 cut.
- SALT THE PORK 12 HOURS EARLY: Don’t just sprinkle salt before cooking. For a 10 lb loin, mix 2 tbsp kosher salt per pound (yes, that’s 20 tbsp total) and let it sit uncovered in the fridge. The salt penetrates deeper, and the surface dries slightly—this crusts better when searing. I skip this when I’m lazy, but the difference in juiciness is noticeable.
- SEAR IN BATCHES OR RISK STEAMING: A 10 lb loin won’t fit in a skillet without crowding. Cut the onion into ¼-inch slices and sear those first in the butter until golden—this renders fat and preheats the pan. Then, work in batches: sear the pork for 3-4 minutes per side until deep brown. Overcrowding turns your crust into sad, soggy pork. (Your future self will thank you.)
- REST IT UNDER FOIL, NOT ON THE COUNTER: After roasting, tent the pork with foil and let it rest 15-20 minutes—this keeps it warm while juices redistribute. I used to rush this, and the first slice was always dry. The foil traps heat better than a cutting board, and it’s less messy. (Yes, even if you’re impatient like me.)
Storing and reheating this 10 lb pork loin
Refrigerator Storage
After your 10 lb pork loin rests, slice it against the grain and store leftovers in an airtight container with the pan juices. I use glass Pyrex containers for even heat distribution when reheating.
Keep refrigerated at 40°F or below for up to 4 days—the flavors actually deepen overnight. For best texture, store in single-serving portions to minimize reheating. 💪
Freezer Preservation
For longer storage, wrap tightly in plastic wrap followed by heavy-duty foil to prevent freezer burn. I recommend vacuum-sealing for maximum freshness—this keeps pork tender and juicy for up to 3 months.
Label packages with the date and cooking method for reference. Thaw overnight in the refrigerator before reheating. ❄️
Stovetop Reheating
My preferred method maintains that restaurant-quality texture. Heat 1-2 tablespoons of the reserved pan juices in a skillet over medium-low heat, then add sliced pork. Cover and warm for 5-7 minutes, stirring occasionally.
The residual juices prevent drying—this is key for pork's tenderness. Add a splash of water if needed to deglaze any stuck bits. 🔥
Oven Refresh Method
For larger batches, preheat oven to 300°F and arrange pork slices on a baking sheet lined with parchment. Cover loosely with foil and bake for 15-20 minutes, basting with pan juices halfway through.
This gentle reheat preserves moisture better than microwaving. I often use this method for family gatherings when I've made extra. 💛
Microwave Safety
When short on time, use the microwave on 50% power in 1-minute intervals, stirring between each. Cover slices with a damp paper towel to retain moisture. Avoid high power settings—this can dry out the pork. For best results, reheat only what you'll serve immediately. 💡
Leftovers Reinvention
Transform leftover pork into new dishes! I love making pork fried rice with day-old slices, or pork pot pie with a creamy herb sauce. For sandwiches, layer with sharp cheddar and apple slices on crusty bread. The glaze adds sweetness that pairs perfectly with tangy mustard. 🌟

Frequently asked questions
Can I cook a 10 lb pork loin bone-in or boneless?
Bone-in is my preferred method—it stays juicier longer and adds depth of flavor. The bone acts as a natural insulator, helping maintain the perfect pink center. If using boneless, reduce cooking time by 10-15 minutes since it cooks faster without the bone's insulating effect.
What's the best way to ensure a juicy pork loin?
The dry brine (salt applied 24 hours ahead) is your secret weapon—it penetrates deeply for maximum moisture retention. Never skip the 15-20 minute rest after cooking either; this lets juices redistribute throughout the meat. Use a meat thermometer to hit 145°F internal temp for that perfect pink center.
How do I adjust this recipe for a smaller pork loin?
This method scales perfectly! For a 5 lb loin, reduce cooking time by about 30-40 minutes and cut glaze ingredients by half. The same ratio works for 3 lb loins too—just halve everything again. The dry brine technique remains identical regardless of size.
Can I smoke this pork loin instead of roasting?
Smoke at 225°F until internal temp reaches 145°F (about 4-5 hours for 10 lbs). For extra flavor, add hickory or applewood chips during the last hour. The glaze still works beautifully—apply it during the final 15 minutes of cooking for that perfect caramelized finish.
Why does my pork loin turn out dry?
Overcooking is the #1 culprit—pork continues cooking after removal from heat. Always use a thermometer and remove at 145°F. Another common mistake is skipping the rest time; juices need 15-20 minutes to redistribute. For extra insurance, cook at 300°F instead of 325°F to slow the process.
