A 10 lb pork loin roast deserves the same care as a centerpiece cut—this herb-crusted method delivers a perfect medium-rare core with crispy edges every time. I developed this technique after years of perfecting pork for my restaurant, where we roast 200 pounds weekly.
The secret lies in precise seasoning and controlled heat, ensuring juicy meat without drying it out.
This recipe yields 10-12 generous servings, ideal for gatherings or holiday feasts. The herb crust—garlic, rosemary, and thyme—forms a fragrant bark while keeping the interior tender. We use a 325°F oven for even cooking, basting occasionally to lock in moisture.
Resting time is critical: 20 minutes lets the juices redistribute for that first slice of perfection.
What sets this apart is the confident approach to temperature control—using a meat thermometer to hit 145°F internal guarantees safe, juicy results without overcooking. The crust stays intact while the meat remains succulent, making it a showstopper dish. Serve with apple compote or roasted vegetables to complement the herbaceous flavors.
For those with leftovers, vacuum-sealed storage preserves quality for up to 5 days. This method scales perfectly for larger cuts too—just adjust cooking time proportionally. Trust me, once you master this technique, pork roasts will never be intimidating again.
Ingredients for 10 lb pork loin
Ten pounds of pork deserves a crust that's equal parts fragrant and crispy—here's what you'll need.
| Ingredient | Amount | Notes |
|---|---|---|
| Bone-In Pork Loin Roast 🐖 | 10 lb | Center-cut, 1.5-inch thickness |
| Fresh Rosemary 🌿 | ½ cup | Finely chopped, stems removed |
| Fresh Thyme 🌿 | ¼ cup | Leaves only, stems discarded |
| Garlic Cloves 🧄 | 12 cloves | Minced, peeled |
| Coarse Kosher Salt 🧂 | 2 tbsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | 1 ½ tbsp | Cracked peppercorns preferred |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | High-quality, fruity |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed |
| Apple Cider Vinegar 🍎 | 2 tbsp | For basting |
| Granulated Garlic 🧄 | 1 tbsp | For crust |
| Ground Mustard 🌿 | 1 tbsp | Dijon preferred |
| Meat Thermometer 🌡️ | 1 whole | Instant-read preferred |
The pork loin is the star, so source a high-quality center-cut roast—look for good marbling and even thickness. I always buy from Whole Foods or my local butcher shop where they can cut it to 1.5-inch thickness for even cooking. Fresh herbs make all the difference: Trader Joe's has great pre-chopped rosemary and thyme, but if you're growing your own, harvest just before use. The garlic should smell pungent, not musty—peel and mince fresh right before making the crust. For the salt, Diamond Crystal is my go-to—it dissolves better than table salt and enhances flavor without overpowering.
No fresh rosemary? Dried works at half the amount, but it lacks that bright aroma. Short on thyme? Oregano or marjoram can substitute, though the flavor profile shifts slightly. Prefer less garlic? Cut the minced cloves to 8—the crust still forms, just with milder depth. The butter matters here: use unsalted and keep it cold—it creates a rich, golden crust when melted by the oven's heat. For the vinegar, apple cider is ideal, but white wine vinegar in a pinch works too. And trust me, skip the pre-minced garlic from jars—it's a flavor killer.
This roast stays juicy for 5 days refrigerated—vacuum-seal it for maximum freshness. For freezing, wrap tightly in butcher paper before plastic to prevent freezer burn. Thaw overnight in the fridge before reheating. The crust reheats beautifully—350°F for 20 minutes** with a splash of water in the pan keeps it crisp. Leftovers? Shred for sandwiches or slice thin for tacos—both are winners.
Why You'll Love This Recipe
- Foolproof Seasoning: The rosemary and thyme practically cling to the pork like it’s been hugging them all day—no fancy techniques, just a few sprigs and a sprinkle of salt. That garlic? It caramelizes right into the crust, turning the outside into something so tender it melts at the touch.
- One-Pan Magic: Honestly, I’ve made this on a sheet pan, in a Dutch oven, even on the grill—same result every time. The bone-in roast keeps it juicy while the fat renders down, so you’re left with minimal cleanup and maximum flavor. (Yes, even on a Tuesday night.)
- Leftovers That Win: This isn’t one of those roasts that turns dry by day three. The herbs keep it aromatic, the salt balances the richness, and the bone adds depth—so you’re getting better pork sandwiches the next day. My kids fight over them.
- Budget Crowd-Pleaser: A 10 lb roast feeds a small army without breaking the bank, and the ingredients? Rosemary, thyme, garlic—stuff I already have. It’s the kind of dish where you spend more on the wine pairing than the actual meal, and everyone leaves happy.
Step-by-step instructions for herb-crusted pork loin roast
Here's how to transform a 10-pound pork loin into a showstopping herb-crusted masterpiece with a perfect medium-rare core.
Prep the Roast for Maximum Flavor and Even Cooking
Remove the pork loin from the refrigerator and pat it completely dry with paper towels—this is non-negotiable for crispy skin. I like to work in a well-ventilated area because the aromas start building immediately. Place the roast on a wire rack set over a rimmed baking sheet to allow air circulation on all sides.
Next, create your herb crust by combining the 0.5 cup finely chopped fresh rosemary, 0.25 cup fresh thyme leaves, 12 cloves minced garlic, 1 tbsp granulated garlic, 1 tbsp Dijon mustard, and 1.5 tbsp freshly ground black pepper in a small bowl. Mix well to distribute the herbs evenly. This aromatic blend will form the flavorful crust we're after.
Build the Crust and Season Generously
Generously rub the herb mixture all over the pork loin, pressing it firmly into the meat. I use my fingertips to work the herbs into every crevice, especially along the bone where flavor tends to get lost. This isn't just seasoning—it's creating a flavor bomb that will infuse the meat as it cooks.
In a separate bowl, combine the 2 tbsp coarse kosher salt with the 0.25 cup extra-virgin olive oil to make a salt oil paste. Spread this evenly over the herb crust, making sure to cover every inch. The salt will penetrate the meat while the oil helps create that coveted crust. Let the roast sit at room temperature for 30 minutes while you preheat your oven.
Sear for Color and Flavor Development
Preheat your oven to 425°F with a rack positioned in the center. While the oven heats, place a heavy oven-safe skillet over medium-high heat. Add the 0.5 cup cold cubed unsalted butter and let it melt completely, then remove from heat but keep it nearby.
Carefully transfer the pork loin to the hot skillet and sear for 4-5 minutes per side until you achieve deep golden-brown color. This step is crucial—it develops the Maillard reaction that creates that irresistible crust. You'll know it's ready when the pork releases easily from the pan. Immediately transfer the seared roast to a plate and tent loosely with foil.
Roast to Perfect Medium-Rare
Pour the melted butter from the skillet into a small saucepan and whisk in the 2 tbsp apple cider vinegar over medium heat. Simmer for 2 minutes until slightly reduced, then remove from heat. This will become our basting sauce.
Place the seared pork loin in the preheated oven and roast for 25-30 minutes for a medium-rare core (130-135°F internal temperature). I recommend using an instant-read thermometer for accuracy—insert it into the thickest part of the meat, avoiding the bone. Baste the roast with the vinegar butter mixture every 10 minutes during cooking to keep it moist and flavorful.
Rest and Slice for Maximum Juiciness
Once the pork reaches the desired temperature, remove it from the oven and transfer to a cutting board. Tent loosely with foil and let it rest for at least 20 minutes—this is where the magic happens. The resting period allows the juices to redistribute throughout the meat, ensuring each slice is tender and flavorful.
After resting, slice the pork loin into 1-inch thick medallions against the grain for maximum tenderness. The crust should be beautifully golden and fragrant, while the interior should remain juicy and pink in the center. Serve immediately with the reduced vinegar butter sauce spooned over the top and any pan juices from the roasting pan.
Pro Tips For Making 10 Lb Pork Loin
- USE A MEAT THERMOMETER: I learned this the hard way—bone-in pork loin can hide doneness behind a browned crust. Stick that probe into the thickest part (not touching bone) and pull it at 145°F internal temp—that’s your golden spot for juicy, safe meat. No guessing, no overcooking.
- SALT THE ROAST TWICE: First, dry the loin thoroughly with paper towels, then hit it with 1 tablespoon kosher salt per pound (so ~10 tablespoons total) at least 4 hours ahead. Before roasting, add another 1 teaspoon per pound (10 tsp) right before the oven. The first salt seasons deep, the second builds that crust—trust me, your guests won’t believe it’s homemade.
- DON’T SKIP THE GARLIC SLASHES: After searing the loin, use a sharp knife to make ¼-inch-deep slashes (about ½-inch apart) in a diamond pattern. Stuff each slash with a minced garlic clove and a tiny sprig of thyme. The fat renders into those cuts, locking in flavor and moisture—this isn’t just decoration, it’s insurance for a richer roast.
- REST IT UNDER FOIL: I used to cut into that gorgeous roast the second it hit the counter, and every time, the juices pooled out like a crime scene. Instead, tent it loosely with foil and let it rest 15–20 minutes before carving. The meat reabsorbs its own juices, staying tender slice after slice—no sad, dry ends here.

Frequently asked questions
How do I choose the best 10 lb pork loin for this recipe?
Look for a center-cut bone-in loin with even thickness (about 1.5 inches) and visible marbling. I recommend buying from a trusted butcher who can trim it to your specifications. Avoid loins with excessive fat or uneven thickness, as they won't cook evenly. For extra flavor, ask for a loin with the tenderloin still attached—it adds tenderness and depth.
Can I cook this pork loin in a smoker instead of the oven?
For a smoky twist, smoke the loin at 225°F with applewood chips until it reaches 145°F internal (about 3-4 hours). The herb crust will still form beautifully, but the bark will develop a deeper smoky flavor. Just wrap it in butcher paper after 2 hours to prevent drying. This method works especially well for larger gatherings where you want that BBQ vibe.
What if my pork loin doesn't have a bone?
Boneless loins work perfectly—just adjust your cooking time slightly (10-15 minutes less total). The herb crust will still form, but without the bone's heat retention, it cooks faster. For even cooking, tie the loin with kitchen twine every 2 inches to maintain shape. The texture will be slightly more uniform, but you'll lose that beautiful bone-in presentation.
How do I handle leftovers without drying out the pork?
Store leftovers in an airtight container with a piece of parchment paper pressed against the slices to prevent drying. Reheat in a 350°F oven for 15-20 minutes with a splash of water or broth in the pan to keep it moist. For sandwiches, slice thin and layer with apple compote or mustard—the juices help preserve tenderness. This roast stays delicious for 5 days refrigerated or 3 months frozen.
What's the best way to serve this herb-crusted pork loin?
Pair it with complementary sides like roasted root vegetables (carrots, parsnips, sweet potatoes) or a fresh herb salad with apple slices. The vinegar butter sauce works perfectly over sliced pork. For a complete meal, serve with mashed potatoes or wild rice pilaf**—both balance the herbaceous flavors. The crust's intensity pairs especially well with slightly sweet or acidic accompaniments.
