Rôti de Porc à la Moutarde
This roast pork loin comes out tender and juicy, coated in a sharp, fragrant crust of Dijon mustard, garlic, thyme, and rosemary. A quick white wine pan jus adds richness and acidity, making the dish elegant enough for guests yet practical for a weeknight roast.
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
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
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
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
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
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
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
Slice the pork across the grain into thick medallions and spoon over the mustard-herb jus. Serve immediately.

Notes
- •For the best texture, use a centre-cut pork loin of even thickness so it roasts uniformly within the 60-minute limit.
- •A probe thermometer is highly recommended; pork loin is lean and can dry out quickly if cooked much beyond 63-65°C.
- •For a stricter keto plate, serve with buttered green beans, sautéed spinach, or cauliflower purée.
Background
