Roasted Pork Loin With Mustard Garlic Herbs

A straightforward roast chicken-adjacent method produces a juicy, herb-crusted pork loin with bright mustard undertones and garlic aromatics throughout. The coarse-grain Dijon creates a flavorful crust while herbes de Provence adds complexity. Ideal for weeknight dinners or casual entertaining, this version distinguishes itself through the garlic-slit technique, which infuses the meat directly rather than relying on external seasoning alone.

Tips

Tip 1

Insert garlic slits at least 1 inch deep and space 2-3 inches apart for even flavor distribution throughout the meat.

Tip 2

Use an instant-read thermometer inserted into the thickest part for accurate doneness; pork is safe at 145F but 155F ensures better texture.

FAQ

Can I use a boneless pork shoulder instead?

Yes, but increase roasting time to 1.5-2 hours due to higher fat content and thicker cut. Check internal temperature at 145F minimum.

What if my pork loin is thicker than 2 pounds?

Add approximately 15-20 minutes per additional pound. Always rely on thermometer rather than time for doneness.

How long can I keep leftovers?

Refrigerate up to 3 days in an airtight container. Reheat gently to 140F to avoid drying. Freezes well for up to 3 months.
