The pork loin's quality is non-negotiable here—farm-raised center-cut with visible marbling ensures tenderness. Source from Whole Foods or your local butcher for the best marbling. Fresh herbs make all the difference: Penzeys or Trader Joe's bulk sections carry premium rosemary and thyme. For the garlic, organic cloves with intact skins keep best—peel just before mincing. The Dijon mustard should be smooth, not grainy; Amora is my go-to brand for consistent quality.
No fresh rosemary? Dried at one-third the amount works in a pinch, but the texture won't be as refined. Substitute thyme with oregano at half the quantity if needed. For the olive oil, California Extra Virgin brands like Corto provide the right balance of fruitiness without overpowering. The apple cider vinegar can be swapped for white wine vinegar, but it won't carry the same depth of flavor. If you're short on time, pre-minced garlic from the jar works—just rinse it first to remove excess moisture.
Store the pork loin uncovered in the fridge for up to 24 hours before cooking to develop flavor. Fresh herbs should be wrapped in damp paper towels and stored in sealed containers for 5-7 days. The herb crust mixture can be prepped a day ahead and refrigerated—it actually tastes better after resting. For make-ahead convenience, freeze the crust mixture for up to 3 months in an airtight container. The finished pork loin keeps 3-4 days in the fridge, though it's best enjoyed within 2 days for optimal texture.

Step-by-step instructions for herb-crusted pork loin with perfect crispy edges
This method delivers juicy, tender pork loin with a golden, crackling crust every time.
Prepare the Herb Marinade and Tenderize the Pork
In a small bowl, combine the 1 tbsp apple cider vinegar, 1.5 tbsp Dijon mustard, 2 tbsp extra-virgin olive oil, 1.5 tsp kosher salt, and 0.75 tsp freshly ground black pepper. Whisk until fully emulsified—the mixture should be smooth and slightly thickened. This marinade works double duty: tenderizing the meat while infusing flavor.
Place the 2 lb bone-in pork loin on a cutting board, fat-side up. Using a sharp boning knife, make 6-8 shallow cuts (about ¼-inch deep) across the meat, being careful not to cut into the bone. This creates channels for the marinade to penetrate deeply. Rub the marinade evenly over all surfaces, pressing it into the cuts. Let the pork rest uncovered in the refrigerator for at least 4 hours (overnight is ideal) to maximize tenderness.
Create the Herb Crust and Sear the Pork
Preheat your oven to 425°F with a rack positioned in the lower third. In a small bowl, mix the 0.5 oz finely chopped fresh rosemary, 0.25 oz fresh thyme leaves, 6 minced garlic cloves, 0.25 cup all-purpose flour, 2 tbsp cold cubed unsalted butter, and 0.5 tsp granulated sugar. The sugar will help caramelize the crust for extra crispiness.
Remove the pork from the refrigerator and let it sit at room temperature for 20 minutes. Pat it dry with paper towels—this is critical for achieving a crispy crust. Press the herb-flour mixture firmly onto all sides of the pork, working it into the marinade cuts. The crust should adhere well; if it doesn't, chill the pork for 10 minutes to firm it up.
Roast to Golden Perfection with Crispy Edges
Heat a large oven-safe skillet over medium-high heat until very hot. Place the pork in the skillet and sear for 3 minutes per side until deeply golden brown. The crust should develop quickly—don't rush this step as it builds flavor. Transfer the skillet to the preheated oven and roast for 20-25 minutes for medium-rare (internal temperature 140°F), or until the crust is deep golden brown and the edges start to crisp.
Here's the key: the pork will continue cooking as it rests. Use a meat thermometer to check doneness—145°F for medium-rare, 150°F for medium. If the crust isn't crispy enough after roasting, broil for 1-2 minutes on high, watching closely to prevent burning. The internal temperature will rise 5-10°F during resting, so pull it out slightly early.
Rest and Slice for Maximum Juiciness
Transfer the pork to a cutting board and tent loosely with aluminum foil. Let it rest for 15 minutes—this allows the juices to redistribute throughout the meat. Skipping this step results in dry slices. While resting, preheat your serving plates to maintain warmth.
Slice the pork against the grain into ½-inch thick portions. The bone-in cut makes slicing easier—use a sharp carving knife to separate the meat cleanly from the bone. Serve immediately with the pan juices (strain if you prefer a smoother sauce) and any accumulated drippings. The crust should be shatteringly crisp, while the meat remains tender and moist throughout.
Pro Tips For Making America'S Test Kitchen Pork Loin
- USE A MEAT THERMOMETER: I learned this the hard way—bone-in pork loin can fool you with its exterior color. Pull it at 145°F internal temp (not 160°F, which dries it out), and let it rest before slicing. The bone conducts heat unevenly, so don’t eyeball it.
- SLICE GARLIC THINLY: I used to crush whole cloves and wondered why the flavor was muted. For this recipe, mince the garlic into tiny slivers—it blooms faster and coats the pork better. A quick pulse in the food processor does the trick without turning it to paste.
- DON’T SKIP THE MUSTARD RUB: The Dijon isn’t just for flavor—it’s the glue that helps the herbs stick. Mix it into the herb paste and apply it generously, especially on the bone side. I’ve seen people skip it, and the crust never forms as well.
- SEAR IN BATCHES: Crowding the pan steams the pork instead of browning it. Work in two heats if needed—start with half the slices, sear until golden, then repeat. The first batch will thank you with a crispy crust, not a sad, pale one.

Frequently asked questions
Why does the recipe specify bone-in pork loin?
The bone-in cut stays more moist during cooking and adds rich flavor to the meat. The bone also helps stabilize the herb crust during searing, preventing it from falling off. Plus, it's more budget-friendly than boneless cuts while delivering superior texture.
Can I use this recipe for boneless pork loin?
Yes, but with adjustments: reduce cooking time by 5-10 minutes and increase resting time to 20 minutes to compensate for the lack of bone's moisture-retaining properties. For extra crispiness, press the herb crust more firmly and consider adding 1 extra tbsp flour to the mixture. The flavor will still be excellent, just slightly less stable during slicing.
What's the best way to achieve extra crispy edges?
For maximum crispiness, pat the pork completely dry before applying the crust, and use cold butter cubes in the herb mixture. After roasting, broil for 1-2 minutes on high heat while watching closely. The sugar in the crust will caramelize beautifully, creating that perfect shatteringly crisp texture.
How do I prevent the herb crust from falling off?
Make sure the pork is completely dry before applying the crust, and chill it for 10 minutes in the fridge if needed to firm it up. Press the mixture firmly into the marinade cuts, and avoid moving the pork during the initial sear. The flour in the crust acts as a natural glue when properly adhered.
Can I cook this pork loin in a regular oven instead of a skillet?
Preheat the oven to 425°F and place the pork on a wire rack over a baking sheet. Sear it in a separate skillet first (or use the broiler for 3 minutes per side), then transfer to the oven. This method works just as well and gives you more space for larger cuts. The key is still the proper internal temperature and resting time.
