Before you start

Before beginning, gather all your ingredients and equipment. Ensure the pork is removed from the refrigerator at least 20 minutes before it goes into the oven to allow it to come closer to room temperature, which helps with even cooking.

Preheat your oven fully to 400°F (200°C) to ensure the roasting process begins immediately. Scrub the potatoes well and halve them into equal sizes to ensure they cook at the same rate as the pork. Have your cutting board and sharp knife ready for the final carving step.

Ingredients at a glance (3)
  • 3 lb pork loin
  • 2 lb baby potatoes, halved
  • 3 tbsp fresh herbs, chopped

Instructions

Seasoning Phase

  1. Season the Pork and Potatoes
    Preheat the oven to 400°F (200°C). Arrange the baby potatoes around the pork loin in a large roasting pan. Sprinkle the fresh chopped herbs over the pork and potatoes. Use your hands to toss the potatoes and coat the pork evenly, ensuring the herbs adhere well to the surface of the meat for maximum flavor.
    Look for The potatoes are arranged and the herbs are distributed over the pork.
    Tip Pat the pork dry with paper towels before seasoning to ensure the herbs stick perfectly to the meat.

The pork and potatoes should be evenly coated with herbs. Look for a uniform distribution across all surfaces. Ensure the potatoes are arranged in a single layer around the pork, not piled on top, so they roast evenly without becoming mushy or steaming in the pan.

Roasting Phase

  1. Roast to Perfection
    Place the roasting pan in the center of the oven and roast for approximately 50 to 60 minutes. Monitor the progress closely; the pork should develop a beautiful golden-brown crust, and the potatoes should be fork-tender and slightly crisp at the edges. Use a meat thermometer to check that the pork reaches a safe internal temperature of 145°F (63°C) at the thickest part. Let the meat rest at least 3 minutes before carving.
    Look for The pork is golden brown and the potatoes are soft when pierced with a fork.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip If the potatoes finish before the pork, remove them from the pan and keep them warm while the meat finishes roasting.

The pork should develop a deep, golden-brown exterior. The potatoes should be tender when pierced with a fork and show signs of browning on the cut sides.

The kitchen should smell fragrant and savory, and the juices at the bottom of the pan should be bubbling and slightly thickened.

Resting and Carving Phase

  1. Rest, Carve, and Serve
    Remove the pan from the oven and carefully transfer the pork loin to a cutting board. Let the meat rest for at least 10 minutes before carving. This resting period allows the juices to redistribute throughout the meat, ensuring every slice is moist and tender. After resting, carve the pork into thick slices and serve immediately alongside the roasted potatoes, drizzling any pan juices over the meat for extra flavor.
    Look for The juices have settled and the meat is easier to slice without falling apart.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Use a sharp carving knife to achieve clean, professional-looking slices for a beautiful presentation on the serving plate.

The pork must rest for at least 10 minutes on a clean board. When carving, use long, smooth strokes to create even slices. The meat should be moist, light in color, and easy to slice. The potatoes should be ready to serve alongside, having absorbed the delicious pan drippings.

Common mistakes

A common mistake is failing to let the meat rest after roasting. Resting is non-negotiable; cutting into the pork too soon will cause the flavorful juices to leak out, resulting in dry meat.

Another error is overcrowding the pan. Ensure there is enough space around the pork and potatoes for heat to circulate, which is necessary for achieving a proper sear rather than steaming the ingredients.

How to tell it’s done

The pork loin is perfectly done when it reaches an internal temperature of 145°F (63°C). At this stage, the meat will be firm yet tender, and the juices should run clear.

It is crucial to use a meat thermometer inserted into the thickest part of the loin to verify this temperature. Avoid overcooking, as pork loin can quickly become dry if left in the oven for too long beyond the recommended time.
