Pork tenderloin in a creamy mushroom sauce is a Czech favourite for a relaxed evening, and it needs only one skillet for the main part. This home-kitchen adaptation takes its idea from a classic Czech dish of pork with mushroom sauce, but it serves the meat with simply boiled potatoes instead of potato fritters and uses cooking cream. It is an adaptation, not a traditional recipe.

Method

  1. Simmer the potatoes

    Put the whole potatoes and the water in a pot. Bring to a boil over high heat, then reduce the heat to medium-low and simmer for 20 minutes, until a knife slides in easily. Keep the pot covered.

  2. Sear the pork

    Heat the olive oil in a 26 cm skillet over medium-high heat. Season the pork medallions with the salt and the black pepper, then sear them for 2 to 3 minutes per side until golden-brown. Move them to a plate and set aside.

  3. Soften the mushrooms and onion

    Melt the butter in the same skillet over medium heat. Add the chopped onion and cook for 3 minutes until soft, then add the sliced mushrooms and cook for 8 to 10 minutes, until they release their liquid and turn golden-brown.

  4. Build the cream sauce

    Stir in the thyme leaves and the cooking cream. Simmer gently for 5 minutes, until the sauce thickens slightly and coats the back of a spoon. Keep it below a hard boil.

  5. Finish the pork

    Return the pork medallions and their juices to the sauce. Spoon the sauce over them and simmer gently for 3 to 4 minutes, until the pork is cooked through and reaches 63 °C at the thickest point with no pink left.

  6. Serve

    Drain the potatoes and place them on warm plates beside the pork. Spoon the mushroom cream sauce over the meat and serve at once.

Good to know

  • Pat the pork dry with kitchen paper before searing and leave space between the medallions, so they brown instead of steaming.
  • Cook the mushrooms until they release their liquid and the pan looks almost dry again before the sauce goes in; this deep browning gives the sauce its flavour.
  • Keep the cream at a gentle simmer. A hard boil can make a cream sauce separate and turn grainy.
  • Check the thickest piece of pork with a thermometer: 63 °C is the target for pork tenderloin, and the meat should look fully opaque inside.
