10 Pound Pork Loin Recipe: Herb-Crusted Roast With Juicy Pink Centers

A 10 lb pork loin transforms any gathering into a showstopper—juicy, tender, and packed with flavor that keeps guests asking for seconds. I’ve perfected this herb-crusted roast over years of cooking for crowds, ensuring the center stays pink and succulent while the crust develops a golden, aromatic crust.

The secret lies in precise temperature control and a well-balanced seasoning blend that enhances, rather than overpowers, the natural richness of the meat.

This recipe is designed for those who want restaurant-quality results without the guesswork. The herb crust—a mix of fresh rosemary, thyme, garlic, and Dijon—adheres beautifully to the pork, infusing it with layers of flavor as it roasts.

A low-and-slow approach ensures the meat stays moist, while a final sear in a hot pan locks in juices for that perfect bite. No fancy equipment is needed—just a reliable thermometer, patience, and a cast-iron skillet.

By the time you pull it from the oven, you’ll have a juicy, golden-brown roast that slices effortlessly and delivers melt-in-your-mouth tenderness.

The crust will be fragrant and slightly crisp, while the interior remains tender and pink at the core—a nod to the traditional style that keeps every bite satisfying.

This is the kind of pork loin that makes you look like a pitmaster, even if you’re cooking in your home kitchen.

Serve it alongside roasted root vegetables, a tangy apple-cider glaze, or a crisp green salad to round out the meal. The leftovers? Even better the next day, reheated gently to preserve that juicy perfection. Let’s get started—this is pork loin done right.

Ingredients for 10 lb pork loin

Ten pounds of pork loin deserves a flavor-packed herb crust and juicy pink perfection inside.

The pork loin is the star—bone-in, center-cut is non-negotiable for even cooking. Costco or Whole Foods usually carry perfect 10 lb loins already trimmed, but if you're buying whole, ask the butcher to remove the silver skin. Fresh herbs make all the difference: rosemary and thyme from the grocery store's refrigerated section (not the dried stuff) will give you that restaurant-quality aroma. The garlic? Freshly minced—pre-minced jars taste flat. For the crust, Dijon mustard adds depth, while the olive oil ensures a golden, crisp exterior. Don't skip the kosher salt—it dissolves better than table salt and enhances flavor without overpowering.

No fresh rosemary? Dried works at one-third the amount, but it won't have the same punch. Short on thyme? Oregano or savory can substitute, but reduce to half. The butter for searing should be cold and unsalted—salted butter can make the crust too salty. For the glaze, apple cider vinegar cuts through the richness, while brown sugar adds caramelized sweetness. No vinegar? Lemon juice works in a pinch. The vegetable oil in the roasting pan prevents sticking and makes cleanup easier—just don't let it pool under the meat. And that thermometer? Invest in a good one—your pork's life depends on it.

This roast reheats like a dream—gentle oven or stovetop only, no microwave. Wrap tightly in foil and reheat at 300°F for 20 minutes to keep it juicy. Leftovers keep 4-5 days in the fridge, but honestly, they won't last that long. For a crowd, make the glaze ahead and store it separately. The crust mix can be prepped 24 hours early—just keep it refrigerated. Slice against the grain for maximum tenderness, and save the bones for a rich pork broth later. Trust me, you'll want to make this again.

Step-by-step instructions for herb-crusted pork loin roast

Here's how to transform a simple pork loin into a showstopping centerpiece with perfect pink centers and aromatic herb crust.

In a food processor, pulse together the 0.5 cup fresh rosemary, 0.25 cup fresh thyme, 12 cloves garlic, 2 tablespoons kosher salt, and 1 tablespoon freshly ground black pepper until finely chopped but not pasty. Transfer this mixture to a bowl and stir in the 0.25 cup Dijon mustard and 0.5 cup extra-virgin olive oil until it forms a thick, cohesive paste. This herb mixture will create the flavorful crust that seals in juices during roasting.

For best results, I like to let this mixture sit at room temperature for 15 minutes before applying. This allows the flavors to meld slightly and makes it easier to work with. The Dijon mustard adds depth while helping the crust adhere to the meat.

Pat the 10 lb bone-in pork loin completely dry with paper towels—this is critical for achieving crispy skin. Using your hands, generously coat the entire surface with the herb mixture, pressing firmly to ensure even coverage. Pay special attention to the fat cap and edges where flavor tends to concentrate.

Place the crusted pork loin on a rack set inside a roasting pan. This elevation allows hot air to circulate evenly around the meat. Pour 0.25 cup vegetable oil into the bottom of the pan—this prevents sticking and creates additional crispiness. Let the pork rest at room temperature for 30 minutes before roasting.

Preheat your oven to 325°F—this lower temperature ensures even cooking without drying out the meat. Place the pork loin in the center of the oven and insert the meat thermometer into the thickest part of the meat, avoiding the bone. Roast for 2 hours and 15 minutes, or until the internal temperature reaches 145°F for medium-rare (the pink center you're aiming for).

Here's where precision matters: The pork will continue cooking slightly after removal from the oven (carryover cooking), so pull it out when the thermometer reads 140°F. The meat should be tender but still slightly springy to the touch. For extra insurance, tent loosely with foil and let it rest for 20 minutes before carving.

While the pork rests, melt together 0.5 cup unsalted butter, 0.25 cup brown sugar, and 2 tablespoons apple cider vinegar in a small saucepan over medium-low heat. Stir constantly until smooth and slightly thickened—about 5 minutes. This glaze adds a sweet-tangy contrast that complements the herb crust beautifully.

Brush this glaze generously over the pork just before serving. The residual heat from the roast will help it set into a glossy finish. I find this step elevates the dish from good to exceptional, adding both visual appeal and flavor complexity.

After resting, carve the pork loin into 1-inch thick slices against the grain for maximum tenderness. The herb crust should be golden and crispy, while the interior should remain juicy pink with just a hint of pink in the center. Serve immediately with the glaze drizzled over each slice and any accumulated pan juices spooned alongside.

This method guarantees a pork loin that's perfectly cooked through with a flavorful exterior and succulent interior—every bite delivers that satisfying contrast of textures and flavors. The herb crust keeps it moist while adding aromatic complexity, making this roast worthy of any special occasion.

Wine and beer pairings for this dish

Red Wine Classics

For this herb-crusted pork loin, I always reach for a Burgundy—specifically a Pinot Noir from the Côte de Nuits region. The earthy, red-fruit notes and subtle oak complement the rosemary and thyme beautifully, while its medium body won’t overpower the dish.

A 2018 Domaine Drouhin is my go-to, but even a well-made California Pinot Noir works in a pinch. 🍷

If you prefer something bolder, a Syrah from the Northern Rhône—like a Crozes-Hermitage—brings peppery notes that pair wonderfully with the crust’s garlic and Dijon. These wines cut through the richness while enhancing the herbaceous flavors.

I’ve also enjoyed a Tempranillo from Spain, particularly when the pork is glazed—its bright acidity cleanses the palate between bites.

Crisp White Alternatives

Don’t dismiss whites! A Chardonnay with good acidity—like a Meursault or Santa Barbara County—works surprisingly well, especially if you prefer lighter pairings. The buttery notes in the wine mirror the pork’s richness, while its citrus finish balances the herb crust.

I’ve also found dry Riesling from Germany or Alsace to be excellent, particularly with the apple cider glaze. 🍷

For a budget-friendly option, a Sauvignon Blanc from New Zealand or Loire Valley offers zesty acidity that brightens the dish. The grapefruit notes in the wine play off the rosemary’s piney aroma, creating a refreshing contrast. Just avoid overly oaky whites—they’ll clash with the delicate herb flavors.

Beer Pairings

When it comes to beer, I lean toward Belgian-style ales—specifically a saison or farmhouse ale—for their peppery, herbal notes that echo the crust’s rosemary and thyme. A Cantillon Gueuze or Brouwerij Boelens Saison adds a funky depth that’s unexpected but brilliant. 🍺

For a more approachable option, a German Helles or American pale ale with citrusy hops provides a crisp, clean palate cleanser. Avoid heavy stouts or IPAs—they’ll overpower the pork’s delicate flavors.

If you’re serving the glaze, a Belgian witbier with its coriander and orange peel notes adds a bright, refreshing contrast.

Regional Specialties

In the Southeast, where I grew up, we often paired pork loin with Georgia Chardonnay—local wineries like Chateau Elan craft excellent examples with enough acidity to stand up to the herb crust.

For a true Southern twist, a Moscato d’Asti from Italy adds a touch of sweetness that complements the glaze beautifully. 🍇

If you’re cooking for a crowd, consider a Southern-style bourbon barrel-aged red—like a Cabernet Sauvignon from Kentucky. The vanilla and oak notes from the barrel enhance the pork’s richness, while the wine’s structure holds its own against the herb crust.

It’s a bold choice, but one that always impresses guests.
