Boneless Pork Loin Rib Half Recipe: Herb-Crusted Roast With Moist Core

This boneless pork loin rib half recipe delivers the perfect balance of herb-crusted richness and moist, tender meat—the kind that makes every bite worth the effort. 🔥 I developed this after years of perfecting pork roasts for my restaurant, where we serve 2,000 pounds weekly, and it’s now my go-to for family gatherings.

The secret lies in a two-stage cooking method that locks in juices while building a flavorful crust. What sets this recipe apart is the herb crust, a blend of rosemary, thyme, and garlic that clings to the meat without overpowering its natural sweetness.

Unlike traditional roasting, which can dry out the center, this technique ensures a juicy core with a golden, aromatic exterior. The pork starts with a salt cure to enhance tenderness, followed by a low-and-slow roast that guarantees even cooking.

By the time you carve into this roast, you’ll find perfectly pink centers and a crust so flavorful it’ll have everyone asking for seconds. The herbs infuse the meat with earthy depth, while the slow cooking process keeps it moist and succulent—no dry, rubbery pork here.

This is the kind of dish that transforms a weeknight dinner into a showstopper. Serve with roasted root vegetables or a crisp apple sauce to complement the richness. The leftovers reheat beautifully, making it ideal for meal prep or feeding a crowd. Let’s get cooking!

Ingredients for boneless pork loin rib half

Six ingredients transform this pork into a restaurant-quality roast with juicy centers and aromatic crust.

The pork loin rib half is the star—look for center-cut pieces with good marbling at Whole Foods or your butcher. A 4-pound half feeds six generously, but adjust up or down as needed. The Diamond Crystal kosher salt is key for the cure—it dissolves cleanly. Fresh herbs matter here: rosemary and thyme from the grocery store's produce section work, but local farmers markets often have more vibrant options. For the garlic, peel and mince it yourself—pre-minced loses flavor fast. The butter should be cold when you cube it for the crust.

No fresh rosemary? Dried works at half the amount, but it won't have the same aromatic punch. Short on thyme? Oregano at two-thirds the quantity gives a similar earthy note. The apple cider vinegar adds brightness—white wine vinegar in a pinch. For the honey glaze, maple syrup works if you're avoiding honey, though it has a different finish. The flour is just for dusting before roasting—don't skip it, but don't overdo it either. If you're making this ahead, prep the herb crust and cure the pork 24 hours early—it develops deeper flavor that way.

The cured pork keeps 2 days in the fridge before roasting—use a sealed container. Fresh herbs stay vibrant for 3 days wrapped in damp paper towels. The herb crust mixture can be prepped a week ahead and stored in the freezer. Leftovers reheat beautifully—warm in a 325°F oven for 15 minutes with a splash of broth to keep them moist. This roast freezes well for 3 months if wrapped tightly in butcher paper and foil.

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

Here's how to transform a simple pork loin into a showstopping centerpiece with a crispy crust and juicy interior.

In a bowl, combine the 0.75 cup kosher salt, 1 tbsp apple cider vinegar, and 1 tbsp honey until fully dissolved. This mixture creates a dry brine that penetrates deeply for unmatched seasoning and moisture retention. Pat the 4 lb boneless pork loin rib half completely dry with paper towels—this step is non-negotiable for crispy skin.

Rub the salt cure mixture all over the pork, pressing firmly to ensure even distribution. Wrap the pork tightly in plastic wrap and refrigerate for 24 hours. Here's the thing—this overnight cure works magic by breaking down muscle fibers, allowing the salt to penetrate deeply. Don't skip it; this is what guarantees that moist core you're after.

In a food processor, combine the 0.5 cup unsalted butter (cold and cubed), 0.25 cup fresh rosemary, 0.25 cup fresh thyme, 8 cloves minced garlic, 1.5 tsp freshly cracked black peppercorns, 1 tsp granulated garlic, and 0.5 tsp dried mustard powder. Pulse until the butter is fully incorporated but still slightly textured—you want visible herb flecks for maximum flavor impact.

Remove the pork from the refrigerator and let it sit at room temperature for 30 minutes. This equalizes the internal temperature for even cooking. Spread the herb butter mixture evenly over the entire surface of the pork, pressing gently to adhere. The butter should feel cold to the touch—this ensures it will crisp beautifully during roasting.

Preheat your oven to 425°F with a rack positioned in the lower third. Place the pork on a wire rack set over a rimmed baking sheet (this allows air circulation for crispy skin). Dust lightly with the 0.25 cup all-purpose flour—this creates a delicate crust that browns beautifully.

Roast for 25 minutes at 425°F, then reduce heat to 325°F and continue cooking for 45-55 minutes (depending on thickness) until the internal temperature reaches 145°F at the thickest part. Here's the critical moment: the pork is done when it reaches 145°F and has rested for 10 minutes—this is when the juices redistribute for maximum tenderness. Use a meat thermometer for accuracy.

Transfer the pork to a cutting board and tent loosely with aluminum foil. Let it rest for 15 minutes—this is where the magic happens as the juices redistribute throughout the meat. While it rests, heat 0.5 cup extra-virgin olive oil in a small saucepan over low heat until shimmering. Add 1 tbsp honey and simmer for 1 minute to create a glossy glaze.

Brush the warm honey-oil glaze generously over the pork, then garnish with 0.125 cup chopped fresh parsley. The glaze adds a beautiful sheen and subtle sweetness that complements the herb crust. Slice against the grain into ½-inch thick portions for maximum tenderness in each bite. Serve immediately with roasted vegetables or a fresh herb salad.

Make-ahead tips for this recipe

Prep Ahead Secrets

Start your salt cure 24 hours early—this is where the magic happens. I always prep mine the night before, letting the pork sit in the fridge overnight. The salt and vinegar break down muscle fibers, creating a tender, juicy interior.

Store the cured pork in an airtight container with parchment paper between layers to prevent sticking. 💫

Herb Crust Prep

Make the herb butter crust a week ahead and store it in an airtight container in the freezer. When ready to cook, simply thaw it in the fridge for 2 hours before applying.

I like to wrap it in plastic wrap to keep it compact. The herbs stay vibrant longer this way, and the butter maintains its cold texture for that perfect crust.

Partial Cooking

For large gatherings, partially cook the pork halfway through and refrigerate. After the initial 25 minutes at 425°F, wrap it tightly in butcher paper and freeze. When ready to finish, thaw overnight in the fridge, then complete the roast at 325°F until it hits 145°F internal temperature.

This method saves time and keeps the meat perfectly moist.

Freezing Leftovers

Slice the cooked pork and freeze individual portions in airtight containers with a thin layer of honey glaze on top. This prevents drying and keeps flavors bright. When reheating, warm in a 325°F oven for 15 minutes with a splash of beef broth to maintain moisture.

I’ve found this method preserves the herb crust beautifully for up to 3 months.

Make-Ahead Serving

Prep your sides the day before—roasted root vegetables or a fresh herb salad keep well in the fridge. Store them in separate containers, so flavors don’t mingle.

On serving day, simply reheat the pork and assemble everything together. This reduces last-minute stress and ensures your guests get a restaurant-quality meal with minimal effort. 💡

Herb Freshness Tip

If you’re prepping herbs ahead, wrap them in damp paper towels and store in a sealed container in the fridge. This keeps rosemary and thyme fresh for up to 5 days.

For even longer storage, freeze chopped herbs in ice cube trays with a bit of olive oil—perfect for adding to the crust later without losing potency.
