• 1 tablespoonDijon mustard
• 2 teaspoonschopped fresh thyme (or fresh parsley)
• ½ teaspoon, or to tastesalt
• ½ teaspoon, or to tasteblack pepper

Instructions

1. 1

   Season the pork

   Season the pork loin all over with 1 teaspoon of salt and 1 teaspoon of black pepper. Leave it at room temperature for about 1 hour.

2. 2

   Rub with spices

   Heat the oven to 200°C (400°F). Mix the olive oil, cumin, coriander, garlic powder and dried thyme in a small bowl. Rub the mixture over every side of the pork and place it on a rimmed baking tray.

3. 3

   Roast the pork

   Roast for 30 minutes, or until browned, then lower the oven to 175°C (350°F) and roast for about another 30 minutes, until a thermometer in the centre reads 63°C (145°F). Start checking after 45 minutes to avoid overcooking. If it browns too quickly, cover it loosely with foil; if the pan juices start to burn, add 120 ml (½ cup) of water.

4. 4

   Rest and slice

   Take the pork out of the oven, cover it with foil and leave it to rest for at least 10 minutes. Slice to serve.

5. 5

   Save the juices

   For the optional sauce, transfer the roast to a chopping board and pour the pan juices into a bowl or measuring jug.

6. 6

   Make the sauce

   Set the roasting tray over a medium heat on the hob and pour in the vermouth. Scrape up the browned bits and simmer until the liquid has reduced by half. Add the chicken stock, cream if using, and reserved pan juices. Cook for about 3–5 minutes, whisking often, until the sauce is thick enough to coat the back of a wooden spoon.

7. 7

   Season and serve

   Take the tray off the heat and whisk in the Dijon mustard, fresh thyme and the remaining salt and pepper to taste. Spoon the sauce over the sliced pork.

What is pork loin roast?

Pork loin roast is a large, relatively lean cut from the back of the pig, cooked whole and sliced to serve. This American-style version pairs it with a cumin, coriander and thyme rub, then offers a pan sauce made from the roasting juices.

The spice coating gives the surface a savoury, aromatic flavour, while a brief rest helps the slices stay juicy. The sauce is optional, so the roast can suit a simpler dinner as well as a more dressed-up meal.

Nutrition and macros by portion

The nutrition label shows one serving as written: 319 calories, 39g protein, 2g carbs, 15g fat.

The pork supplies most of the protein, while the olive oil and optional cream contribute fat; the small amount of carbohydrate comes mainly from the seasoning and sauce ingredients. Serve with vegetables and a suitable starchy side to round out the plate.

Choosing the pork

Cut: Use a pork loin roast, not a tenderloin; they are different cuts and have different cooking times. Keep the roast whole so it cooks evenly and can be carved into slices.

Seasoning: Salt and pepper go directly on the meat, while the olive oil helps the dried spices form a coating. The vermouth is for the optional sauce and can be replaced with chicken stock.

Build the spice rub

Mixing: Stir the oil, cumin, coriander, garlic powder and dried thyme together before rubbing them over the roast. Cover the ends and sides as well as the top for an even layer of flavour.

Surface: A rimmed baking tray catches the juices and makes it easier to prepare the sauce afterward. If the drippings look as though they are burning, add the specified water to the tray.

Check for doneness

Thermometer: Begin checking after 45 minutes, inserting the thermometer into the centre of the roast. The method calls for a reading of 63°C (145°F); oven times can vary, so use the temperature cue rather than relying only on the clock.

Colour: If the exterior browns too quickly while the centre is still cooking, tent the roast loosely with foil. Avoid cutting into it to check, as that lets juices escape.

Rest before carving

Resting: After roasting, leave the meat covered with foil for at least 10 minutes before slicing. This pause also gives you time to make the optional sauce.

Carving: Slice the rested roast across the grain where it is visible, using a sharp knife. Cut slices to your preferred thickness and serve while warm.

Finish the optional sauce

Deglazing: Pour vermouth into the roasting tray over medium heat and scrape up the browned bits. Reducing the liquid by half concentrates its flavour before the stock and cream go in.

Texture: Whisk regularly as the sauce cooks for 3–5 minutes, and stop when it coats the back of a wooden spoon. Add the Dijon mustard and fresh thyme off the heat, then adjust the salt and pepper to taste.

What to serve alongside

Sides: Serve the slices with roast potatoes, mash or another filling side, plus a green vegetable such as green beans or broccoli. These additions make a balanced dinner and work well with the pan sauce.

Sauce: Pass the sauce at the table or spoon it over the pork just before serving. For a dairy-free version, use additional chicken stock instead of cream.

Recipe notes & tips

• Letting the seasoned roast stand for about 1 hour brings it to room temperature as directed in the method.
• Use a rimmed tray to keep the roasting juices contained for the optional sauce.
• Start checking the centre temperature after 45 minutes, as ovens and roasts can vary.
• Tent the roast loosely if the outside is browning faster than you want.
• Keep a little water nearby to add to the tray if the drippings begin to burn.
• Whisk the sauce often as it thickens to help it cook evenly.

Variations

• Dairy-free sauce: Replace the cream with additional chicken stock as indicated.
• Herb swap: Use chopped fresh parsley instead of fresh thyme in the sauce.
• Stock in place of vermouth: Use chicken stock instead of vermouth when deglazing.
• Different alcohol: Replace the vermouth with your preferred alcohol for the sauce.
• Sauce-free roast: Serve the rested pork without making the optional pan sauce.

Common mistakes to avoid

• Using tenderloin: Choose pork loin roast, since tenderloin is a different cut and will not follow the same timing.
• Skipping temperature checks: Begin checking after 45 minutes and use the centre reading to judge doneness.
• Over-browning: Cover the roast loosely with foil if its surface darkens too quickly.
• Burning pan juices: Add 120 ml (½ cup) water to the tray if the juices start to burn.
• Slicing too soon: Rest the roast under foil for at least 10 minutes before carving.
• Rushing the sauce: Reduce the vermouth by half before adding the stock and cream.

How to store

Refrigerate leftover pork and sauce in separate airtight containers and use within 3 days. Reheat gently until hot, adding a splash of stock to the sauce if it has thickened; avoid prolonged heating, which can dry out the pork.
