Ingredients

Rôti et assaisonnement

  • 500 gpork loin, trimmed
  • 30 gDijon mustard
  • 2 clovesgarlic, finely grated
  • 2 tspfresh thyme leaves
  • 1 tspfresh rosemary, finely chopped
  • 6 gfine sea salt
  • 1 tspblack pepper, freshly ground
  • 10 mlolive oil

Jus de cuisson

  • 20 gbutter
  • 100 mldry white wine
  • 100 mlchicken stock, unsalted

Instructions

  1. 1

    Preheat the oven to 220°C. Pat the pork loin very dry with kitchen paper so it browns properly. In a small bowl, mix the Dijon mustard, grated garlic, thyme, rosemary, salt, pepper, and olive oil into a paste.

  2. 2

    Rub the mustard-herb paste all over the pork loin, pressing it on evenly. Let it stand at room temperature for 10 minutes while the oven finishes heating; this takes the chill off and helps the meat cook more evenly.

  3. 3

    Heat a heavy ovenproof skillet over medium-high heat. Add the pork and sear for 1-2 minutes per side until lightly browned; do not move it too soon or the crust will tear. Add the butter to the pan in the last minute and baste briefly for extra color.

  4. 4

    Pour the white wine and chicken stock around the pork to deglaze the pan, scraping up the browned bits. Transfer the skillet to the oven and roast for 18-22 minutes, or until the thickest part reaches 63°C for juicy pork. If the top darkens too quickly, lower the oven to 200°C for the final minutes.

  5. 5

    Transfer the pork to a warm plate and rest for 10 minutes, loosely tented with foil. Resting is essential so the juices redistribute instead of running out when sliced.

  6. 6

    Meanwhile, place the skillet over medium heat and simmer the pan juices for 3-5 minutes until lightly reduced and glossy. Swirl the pan rather than stirring constantly so the sauce emulsifies smoothly.

  7. 7

    Slice the pork across the grain into thick medallions and spoon over the mustard-herb jus. Serve immediately.
