Instructions

1. 1

   Mix the marinade

   Put the Dijon mustard, honey, paprika, whisky, salt and some olive oil on a plate or in a dish, then mix them together.

2. 2

   Marinate the pork

   Set the tenderloins in a fairly snug dish and coat them with the marinade. Cover with cling film and refrigerate for 8–10 hours.

3. 3

   Prepare the pears

   Peel and core the pears, then sprinkle them with the tablespoon of sugar and the ginger. Add the balsamic vinegar.

4. 4

   Cook the pears

   Put the pears in a resealable bag and press out the air before sealing it. Lower the bag into a pot of boiling water, weigh it down with a plate to keep it submerged, and cook gently for 8 minutes. Take the pot off the heat and leave the pears in the hot water until serving.

5. 5

   Sear the pork

   Lift the tenderloins out of the marinade and pat them a little dry. Heat a little olive oil in a frying pan and sear the meat on all four sides.

6. 6

   Roast the pork

   Transfer the tenderloins to an oven dish and roast for 20 minutes at 180°C. Make sure the oven has been preheated for at least 20 minutes.

7. 7

   Soften the onion

   Slice the onion finely. Melt the butter, add 1 tablespoon of olive oil and the onion, then sprinkle over 1/2 teaspoon of sugar. Cook gently for 8–10 minutes without letting the onion brown.

8. 8

   Purée the onion

   Blend the softened onion mixture into a purée.

9. 9

   Boil the sauce

   Pour the leftover marinade into a saucepan and bring it to the boil. Cook it for a couple of minutes.

10. 10

    Rest and serve

    Take the pork out of the oven, cover it with foil and leave it to rest for 5 minutes. Slice and serve with the sauce, pears and onion purée.

What is mustard-marinated pork tenderloin?

Pork tenderloin is a lean, tender cut that cooks relatively quickly once it is in the oven. This version pairs it with a mustard, honey and whisky marinade, then serves it with gently cooked pears and a smooth onion purée.

The combination draws on familiar European flavours rather than one specific regional tradition: sharp mustard and balsamic meet sweet fruit and mellow onion. Marinating the pork well ahead gives the flavour time to settle into the meat.

Nutrition and macros by portion

The nutrition label shows one serving as written: 500 calories, 44g protein, 33g carbs, 22g fat.

Pork provides most of the protein, while the honey, pears and sugar contribute most of the carbohydrates. Butter and olive oil supply much of the fat; the exact amounts of salt and the unspecified olive oil will affect the nutrition estimate. For a balanced plate, serve a moderate amount of pork and purée with extra vegetables or salad.

The marinade’s balance

Mustard: Dijon brings a mild sharpness, while honey softens its bite and helps the marinade cling to the pork.

Whisky: A small amount adds depth alongside the paprika. Mix the marinade thoroughly before coating the tenderloins so the flavours are distributed evenly.

Why sear before roasting

Searing: Brown the tenderloins on all four sides in a little oil before they go into the oven. This gives the outside colour and flavour; it does not replace cooking the pork through in the oven.

Drying: Pat the meat lightly after removing it from the marinade. A less wet surface is easier to brown in the pan.

Keep the onion pale

Gentle heat: Cook the finely sliced onion in butter and olive oil for 8–10 minutes, keeping the heat low so it softens without browning. The recipe’s purée is intended to be mild and smooth rather than caramelised.

Butter: It contributes much of the purée’s rich flavour. Blend the softened onion mixture until smooth, then serve it as a soft base or alongside the pork.

Pear texture and timing

Pears: Peeling and coring before cooking makes them easier to serve. The sugar, ginger and balsamic give the fruit a sweet-tangy seasoning.

Hot water: The recipe cooks the sealed pears gently for 8 minutes, then leaves them in the hot water until serving. Prepare them while the pork is marinating or cooking so they are ready at the table.

Plan the cooking around the marinade

Advance preparation: The pork needs 8–10 hours in the fridge, so start the day before or in the morning. The stated 100-minute total does not include this long marinating period.

Oven timing: Preheat the oven for at least 20 minutes, then roast the seared tenderloins for 20 minutes at 180°C. Rest them under foil for 5 minutes before slicing.

What to serve alongside

The pears and onion purée are already part of the dish, giving the plate fruit and a soft, savoury accompaniment. Add a simple green salad or steamed vegetables if you would like a fresher contrast.

Slice the pork across the grain and spoon a little of the cooked marinade over it. Keep any extra sauce separate so everyone can add as much as they like.

Recipe notes & tips

• Marinate the pork in the fridge for the full 8–10 hours for the recipe’s intended preparation.
• Use a snug dish so the marinade can coat the tenderloins well.
• Preheat the oven for at least 20 minutes before roasting.
• Turn the tenderloins as needed to sear all four sides evenly.
• Keep the onion cooking gently so it softens without browning.
• Rest the pork under foil for 5 minutes before slicing.

Variations

• Fresh ginger: Grate fresh ginger in place of the ground ginger.
• Different spirit: Use another strong spirit instead of whisky, as the ingredient list allows.
• More mustard: Add a little extra Dijon for a sharper marinade.
• Herb finish: Scatter chopped parsley over the sliced pork just before serving.
• Extra greens: Serve with steamed green vegetables for a fresher contrast.

Common mistakes to avoid

• Skipping the marinade: Allow 8–10 hours in the fridge rather than treating the oven time as the whole preparation.
• Wet pork: Pat the tenderloins lightly dry after marinating so they can sear more readily.
• Crowded pan: Sear the tenderloins with enough space to turn them and brown all four sides.
• Browning the onion: Keep the heat low and cook for 8–10 minutes without letting it colour.
• Cutting too soon: Rest the pork under foil for 5 minutes before slicing.
• Removing the pears early: Leave them in the hot water after taking the pot off the heat, as directed.

How to store

Refrigerate leftover pork, pears, purée and sauce in separate airtight containers for up to 3 days. Reheat the pork gently until hot, taking care not to overcook it; warm the pears and purée separately.
