Prosciutto and Pistachio Stuffed Pork Tenderloin Recipe

A mouth-watering Italian-inspired Stuffed Pork Tenderloin filled with sausage and mushrooms, wrapped in prosciutto and rolled in pistachios.

This stuffed pork roast delivers big flavour while remaining easy to prepare. It’s ideal for making ahead so you can serve an impressive, comforting meal without spending all day in the kitchen.

What’s the Difference between Pork Loin and Pork Tenderloin?

The loin and the tenderloin (also called pork fillet in some regions) are distinct cuts and should not be confused—cooking times and techniques differ.

Pork loin is broader and thicker, while pork tenderloin is long, narrow and much more tender. Because tenderloin is lean and delicate, it requires less cooking time than a loin. Overcooking will dry it out; the goal is juicy, succulent meat.

How Do You Butterfly Pork Tenderloin?

Butterflying a pork tenderloin is straightforward and only takes a few minutes. Cutting the meat open and flattening it makes stuffing and rolling much easier.

Place the tenderloin on a cutting board and slice lengthwise down the middle without cutting all the way through, then open it like a book. Put the meat between two sheets of plastic wrap and gently flatten with a rolling pin to about 1/2 inch (1.25 cm) thickness.

The Stuffing

The filling is simple but full of flavour: herby Italian sausage combined with sautéed mushrooms, garlic, parsley, rosemary and a little freshly grated Parmesan. It’s an easy mixture that tastes remarkable.

How to Make Stuffed Pork Tenderloin with Prosciutto & Pistachios – Step By Step

Prep Work
Start by pulsing the pistachios in a food processor to a medium-fine crumb—take care not to over-process or they will turn paste-like.

Heat the olive oil in a skillet, sauté the garlic briefly, then add the sliced mushrooms, chopped parsley and rosemary. Cook for 5–7 minutes until the mushrooms are soft and any released liquid has evaporated. Allow the mixture to cool.

Remove the sausage meat from its casings and combine it with the cooled mushroom mix and Parmesan in a bowl.

Butterfly the pork tenderloin and place it between two sheets of plastic wrap. Gently pound with a rolling pin to about ½ inch thickness.

How to Assemble the Pork Tenderloin

On a clean surface, lay a sheet of plastic wrap. Arrange prosciutto slices in an even layer, overlapping them by about 2 inches so they form a sheet long enough to cover the tenderloin with a little overlap at each end.

Place the flattened tenderloin along the prosciutto, season lightly with salt, then press the sausage and mushroom stuffing evenly over the meat. Roll the tenderloin away from you as tightly as possible, using the plastic wrap to help pull it snug.

You can keep the roll wrapped in plastic in the fridge until ready to roast.

When ready to bake, spread the pistachio crumbs on a tray or plate and roll the wrapped tenderloin over them, pressing lightly so some crumbs adhere (not all will stick).

How to Cook It

Preheat the oven to 350°F (180°C).

Lightly drizzle the pistachio-coated tenderloin with no more than ½ tablespoon of olive oil and place it on a baking tray. Cover loosely with aluminium foil to protect the nuts and prosciutto.

Roast covered for 20 minutes, then remove the foil and roast for another 20 minutes. Remove from the oven and rest for 10 minutes before slicing and serving.

Top Tips for Prepping Ahead

This tenderloin is perfect for make-ahead cooking: you can assemble it, keep it wrapped in the fridge for 1–2 days, then roll in pistachios and roast when needed.

Alternatively, prepare two rolls and freeze one (omit the pistachio coating). Thaw in the fridge overnight, roll in the pistachios if desired, and roast when ready for dinner—ideal for stress-free entertaining or busy evenings.

Delicious Sides and Serving Suggestions

This roast pairs beautifully with creamy mashed potatoes and green vegetables. Serve with gravy, or for an Italian touch drizzle browned butter infused with fried rosemary (heat butter with rosemary until golden).

Italian-style sides that complement the dish include sautéed broccolini, rosemary and garlic roast potatoes, or a simple green bean salad with mustard and garlic dressing. These sides enhance the flavours without overshadowing the pork.

Top Tips for Making This Stuffed Pork Tenderloin

• Roast at 180°C (350°F). Use a meat thermometer to check for an internal temperature of about 155°F (68°C) if unsure.
• Cover with foil while roasting at first to prevent the pistachios and prosciutto from burning.
• Rest the meat for at least 10 minutes before slicing so the juices redistribute and the pork stays moist.
• If you don’t want pistachios, you can omit them entirely.
• You can substitute pancetta or bacon for prosciutto if preferred.
