Beef Wellington is one of our all-time favourite dishes and is often requested for special occasion meals but let’s face it, it’s made with beef fillet so not exactly economical.
This Pork and Chestnut Wellington is a good alternative substituting pork fillet (tenderloin) for the beef fillet.
Pork fillet is the long thin part of the loin muscle found on the inside of the ribcage and runs along the back of the pig from the shoulder to the rear. Like beef fillet it is a very lean and tender has a mild flavour and requires quick cooking. It makes an ideal substitute for beef fillet recipes
If overcooked pork fillet can quickly become rather dry. When cooking any meat I really recommend using a thermometer to check the internal temperature of the meat. It is the best way to ensure your meat is cooked without overcooking.
I love my Thermapen which I have had for several years and which I use all the time. It’s a little pricier than others but very fast accurate and robust. But even a cheaper thermometer which can be picked up for around £10, will be a great improvement than relying on timings.
For this recipe aim for an internal temperature over 63°C (145°F). Which is medium and yes it is okay to have a little bit of pinkness to the meat. If you prefer well cooked you need an internal temperature of 71°C (160°F). I keep a handy chart on the fridge to remind me of the temperatures required.
Chestnut and Mushroom Stuffing
The traditional stuffing for a wellington is mushroom. When I first made this recipe it was during the Christmas festivities, so I decided to give the dish a bit of festive twist with the addition of chestnuts.
The resultant stuffing is light and not too highly flavoured so it doesn’t “fight” with the pork. For me it was a double win as one of my boys doesn’t really like mushrooms and yet still enjoyed this stuffing.

I don’t often make puff pastry from scratch and tend to buy ready made. I like to use an all-butter puff pastry, this is a dish for special occasions after all, as I think the flavour is superior.
If I’m feeling extra lazy I even go for ready rolled, actually I more often or not go for this as my local store doesn’t sell it in a block. But of course, you can roll your own It should be about the thickness of a £1 coin. (3mm/ 1/8in)
When folding up the pastry to enclose the meat I find that you can end up with several thicknesses of pastry at each end. To avoid this I first brush the pastry all over with egg, then cut away some of the excess pastry at each end.
You can use these trimming to bridge the gap if your pastry rectangle isn’t quite big enough to meet in the middle. Or to make some decoration of the top of the wellington if you have a surplus. Make sure you press the pastry together so it sticks brushing with a bit more egg if required and place seam side down on a greased baking sheet.
To get a lovely golden finish, brush the pastry parcel all over with egg and sprinkle with some parmesan cheese. I lightly scored the pastry to give it a little pattern. Take care not to cut through the pastry if you do this.
To serve Pork and Chestnut Wellington
Serve cut down the middle lengthways between the two fillets, then cut each half into 3- 4 portions.
Serve the Pork Wellington with a Red Wine Jus (Recipe coming next week) a vegetable of your choice I have served it with my Braised Red Cabbage Recipe, also coming Soon) and some potatoes. This time I’ve gone for my perfect roast potatoes.

Thanks Cat and so much cheaper than beef. I think pork fillet is much underrated.
Corina Blum
This looks like a really tasty alternative to a traditional Wellington! It also reminds me that it’s too long since I ate any kind of Wellington and would love to make one again soon.
Jacqueline Bellefontaine
this is so much more affordable I think pork fillet is a fabulous cut and baking in pastry prevents it drying out.
