Oven Roasted Pork Loin Recipe: Herb-Crusted and Succulent

This oven roasted pork loin delivers herb-crusted perfection with minimal effort. The simple dry rub creates a flavorful crust while keeping the meat succulent and tender throughout.

With a 400°F oven and 20 minutes per pound, this method guarantees juicy results every time. The resting period ensures all those delicious juices stay locked in.

Ingredients for Oven Roasted Pork Loin

Simple ingredients transform into herb-crusted, succulent pork with minimal effort required.

The pork loin is the foundation—opt for bone-in if available for added flavor, though boneless works equally well. Source from Whole Foods or Costco for consistent quality. The dry rub herbs should be freshly purchased (dried herbs lose potency after 6 months). For the olive oil, California Olive Ranch offers excellent extra-virgin options at a reasonable price point.

No fresh herbs? Double the dried quantities for equivalent flavor impact. Short on time? Pre-minced garlic from a jar works in a pinch (though fresh is superior). The Dijon mustard can be substituted with whole-grain mustard for texture variation. If you lack onion powder, granulated onion at the same ratio provides similar results.

The dry rub can be prepared 24 hours in advance and stored at room temperature. The pork loin itself keeps in the refrigerator for 3-4 days before cooking, or freeze for up to 6 months. Always bring to room temperature before applying the rub for optimal flavor absorption.

Step-by-Step Instructions for Oven Roasted Pork Loin

Master the technique for a perfectly herb-crusted roast with juicy, tender meat.

Step 1: Prepare the Herb Rub

In a small bowl, combine the 1 tbsp Kosher Salt, 1 tsp Black Pepper, 1 tbsp Dried Thyme, 1 tbsp Dried Rosemary, 1 tbsp Garlic Powder, and 1 tsp Onion Powder. I rub the dried herbs between my fingers to activate their essential oils, which deepens the flavor profile.

Add the 4 cloves Fresh Garlic Cloves (minced finely) and 1 tbsp Dijon Mustard to the dry mixture. Stir until it forms a thick paste. The mustard acts as a binder, ensuring the rub adheres uniformly to the pork loin and creates a beautiful crust.

This step is foundational. A well-balanced rub guarantees that every bite carries the full depth of the herb and spice blend, with the mustard adding a subtle tang that complements the richness of the pork.

Step 2: Coat and Sear the Pork Loin

Pat the 2 lb Pork Loin dry with paper towels to remove any surface moisture. Moisture prevents proper searing and crisping, so thorough drying is essential. Place the pork on a clean surface and rub the herb paste evenly over all sides, pressing it in firmly so it adheres well.

Heat the 2 tbsp Olive Oil in a large oven-safe skillet or roasting pan over medium-high heat. Once the oil shimmers, add the pork loin and sear for 2-3 minutes per side until the surface develops a golden-brown crust. This initial sear locks in juices and creates a flavorful fond that will enhance the final dish.

Step 3: Roast to Perfection

Preheat your oven to 375°F. If using the optional 2 whole Fresh Rosemary Sprigs and 2 whole Fresh Thyme Sprigs, tuck them under the pork loin in the pan. This adds an extra layer of aromatic complexity as the herbs infuse during roasting.

Transfer the skillet to the preheated oven and roast the pork loin for 45-60 minutes, or until an instant-read thermometer inserted into the thickest part of the meat registers 145°F. Baste the pork with the pan juices every 15 minutes to ensure even browning and moisture retention.

The pork is done when the internal temperature reaches 145°F and the juices run clear. Avoid overcooking, as pork loin can become dry if left in the oven too long. The thermometer is your most reliable tool here.

Step 4: Rest and Serve

Remove the pork loin from the oven and transfer it to a cutting board. Tent loosely with aluminum foil and let it rest for 10-15 minutes. This resting period allows the juices to redistribute throughout the meat, ensuring each slice is moist and flavorful.

After resting, slice the pork loin against the grain into ½-inch thick slices. Serving against the grain shortens the muscle fibers, making the meat more tender. Arrange the slices on a platter, spoon any accumulated pan juices over the top, and serve immediately.

Make-Ahead Tips for Oven Roasted Pork Loin

Prep the Rub Ahead

Mix the dry rub ingredients up to 24 hours in advance. Store in an airtight container at room temperature. I do this the night before to save time on cooking day.

Season the Pork Early

Apply the herb paste to the pork loin and refrigerate uncovered for 4-12 hours. This dry-brine method enhances flavor penetration. Just bring it to room temperature before roasting.

Partial Cook Method

Sear the pork loin, then roast for only 30 minutes at 375°F. Cool completely, refrigerate, and finish roasting the next day. This works great for meal prep. 💡

Freeze for Later

Cook the pork loin completely, let it cool, then slice and freeze in portions. It reheats beautifully in 30 minutes at 350°F covered with foil. Always add a splash of broth to prevent drying.

Rest Before Slicing

If making ahead, let the cooked pork rest 15 minutes, then refrigerate whole. Slice just before serving to maintain moisture. This keeps the meat juicy for up to 4 days. ❄️

Pan Juices Tip

Save those flavorful pan drippings in a jar. Skim off fat and use as a base for gravy or to moisten reheated slices. I keep mine for up to 3 days in the fridge.
