Ingredients

  • 3 1/2 lb boneless center-cut pork loin roast
  • 1 1/2 tbsp olive oil
  • 2 tsp kosher salt
  • 1 tsp black pepper
  • 2 tsp chopped rosemary
  • 1 tsp dried thyme
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1 tbsp Dijon mustard
  • 1 cup low-sodium chicken broth
  • 1 large onion, thickly sliced

Instructions

Follow each step in order. The directions below are written so a beginner can understand what to do, what to look for, and when to move on to the next step.

  1. Step 1.Heat the oven to 350°F and let the pork loin stand at room temperature for about 20 minutes while you prepare the seasoning.
  2. Step 2.Pat the roast very dry and trim only thick surface fat, leaving a thin layer that can baste the meat as it cooks.
  3. Step 3.Mix olive oil, salt, pepper, rosemary, thyme, garlic powder, onion powder, and Dijon into a paste, then rub it over the roast.
  4. Step 4.Arrange the sliced onion in a roasting pan, place the pork fat-side up on top, and pour the broth around rather than over the seasoned surface.
  5. Step 5.Roast uncovered for about 50 minutes before beginning to check the center with an instant-read thermometer.
  6. Step 6.Continue roasting until the thickest center reaches 145°F, checking every 8 to 10 minutes so the lean meat does not overcook.
  7. Step 7.Transfer the roast to a cutting board and tent loosely with foil, keeping the pan and its juices for an optional quick sauce.
  8. Step 8.Rest the pork for at least 15 minutes; this pause is essential for retaining moisture when the roast is sliced.
  9. Step 9.Skim excess fat from the pan juices and simmer them briefly if desired, scraping up browned bits and adjusting seasoning.
  10. Step 10.Slice the pork loin across the grain into 1/2-inch pieces and serve with the warm pan juices and roasted onions.

HELPFUL NOTES

Tips, Substitutions & Storage

Extra guidance to help you get a reliable result, avoid common problems, and know what to do with leftovers.

✓ Recipe Tips

  • Do not confuse pork loin with smaller pork tenderloin.
  • Cook to temperature rather than a fixed number of minutes.
  • A 15-minute rest protects the roast's juices.

! Common Mistakes

  • Overcooking is the main cause of dry pork loin.
  • Pouring broth over the crust can wash off seasoning.
  • Slicing immediately releases too much juice.

↔ Substitutions

  • Use sage in place of rosemary.
  • Use vegetable broth instead of chicken broth.
  • Brush with whole-grain mustard instead of Dijon.

⌂ Storage & Reheating

  • Refrigerate sliced roast for up to 4 days.
  • Reheat covered with a little broth to preserve moisture.
  • Freeze tightly wrapped slices for up to 2 months.
