Step-by-Step Instructions
1. Prepare the Pork
Preheat the oven to 375°F (190°C).
Remove the pork loin from the refrigerator about 20–30 minutes before cooking.
Pat the roast thoroughly dry with paper towels.
Season all sides with salt, black pepper, garlic powder, onion powder, and smoked paprika.
2. Sear the Pork
Heat 1 tablespoon olive oil in a large oven-safe skillet over medium-high heat.
Add the pork loin and sear for approximately 3–4 minutes per side, turning until a deep golden crust develops.
Transfer the pork briefly to a cutting board.
Searing adds another layer of flavor underneath the herb crust.
3. Make the Garlic Herb Crust
In a medium bowl, combine Parmesan, panko breadcrumbs, minced garlic, parsley, rosemary, thyme, Italian seasoning, black pepper, and red pepper flakes if using.
Add melted butter and olive oil.
Stir until the mixture resembles moist crumbs.
Brush Dijon mustard over the top and sides of the seared pork loin.
4. Coat the Pork
Press the garlic herb Parmesan mixture firmly over the top and sides of the roast.
Use your hands or the back of a spoon to help the coating adhere.
Make sure the top receives a generous layer for the deeply textured crust shown in the dish.
5. Begin Roasting
Place the pork back into the skillet or transfer it to a lightly greased roasting dish.
Roast uncovered for approximately 45–65 minutes, depending on the thickness of the loin.
Start checking the internal temperature around the 45-minute mark.
6. Check for Doneness
Insert an instant-read thermometer into the thickest center portion.
Remove the pork from the oven when it reaches 145°F (63°C).
Avoid overcooking pork loin because it is relatively lean and can dry out.
7. Brown the Herb Crust
If the crust needs additional color, switch the oven to broil.
Broil for 1–2 minutes, watching continuously.
The Parmesan and breadcrumbs should become deeply golden and crisp without burning.
8. Rest the Pork
Transfer the roast to a cutting board.
Tent loosely with foil and let it rest for 10–15 minutes.
The resting period allows the juices to redistribute through the pork and keeps the meat moist when sliced.
9. Make the Garlic Butter Sauce
While the pork rests, place the roasting skillet over medium-low heat.
Add butter and minced garlic.
Cook for approximately 30 seconds.
Pour in chicken broth and scrape up the flavorful browned bits from the bottom.
Stir in Dijon mustard, Worcestershire sauce, lemon juice, thyme, salt, and black pepper.
Simmer for 4–5 minutes, until slightly reduced.
10. Slice and Serve
Slice the rested pork loin into approximately ½-inch-thick pieces.
Arrange on a serving platter while keeping some of the herb crust attached to each slice.
Spoon the garlic butter pan sauce around the pork rather than completely over the crust so it stays crisp.
Finish with fresh parsley, rosemary, thyme, and cracked black pepper.
Cooking Tips
- Use pork loin, not pork tenderloin. Pork loin is the larger roast shown here and requires a longer roasting time.
- Pat the pork thoroughly dry before searing for better browning.
- Finely chop the herbs so they adhere evenly to the crust.
- Dijon mustard works as both a flavor booster and adhesive for the Parmesan coating.
- Freshly grated Parmesan creates better flavor and browning than pre-shredded cheese.
- Use an instant-read thermometer rather than relying solely on cooking time.
- Remove the pork at 145°F and allow it to rest before slicing.
- Spoon sauce around the sliced pork so the herb crust stays crunchy.
Serving Suggestions
Serve this garlic herb crusted pork loin with:
- Creamy mashed potatoes

Storage
Store leftover pork in an airtight container in the refrigerator for up to 4 days.
Keep extra pan sauce in a separate container when possible.
Reheat pork gently in a 325°F (165°C) oven, covered loosely with foil, until just warmed through.
Avoid overheating because pork loin can become dry.

- Slice leftover pork thinly for sandwiches with Dijon mustard and cheese.
- Serve it over mashed potatoes with warm garlic butter sauce.

- Use thin slices in wraps with lettuce and vegetables.

FAQs
Can I prepare the herb crust ahead of time?
Yes. Mix the Parmesan, breadcrumbs, garlic, herbs, and seasonings up to a day ahead and refrigerate. Add the butter and oil shortly before coating the pork.
Can I use pork tenderloin instead?
Yes, but tenderloin is significantly smaller and cooks much faster. Begin checking it after approximately 20 minutes.
Can I make this without breadcrumbs?
Yes. Use additional Parmesan combined with finely chopped herbs and garlic for a lower-carb crust.
Can I add more garlic?
Absolutely. Increase the garlic in either the crust or pan sauce according to your preference.
How do I keep pork loin juicy?
Avoid overcooking it. Remove the roast at 145°F (63°C) and allow it to rest for at least 10 minutes before slicing.
