Pork Tenderloin with Mustard Sauce

Pork Tenderloin with Mustard Sauce — Thermomix TM7

Pork tenderloin in a creamy mustard sauce is a classic French-inspired main course for the Thermomix TM7. Tender slices of pork are paired with button mushrooms and a tangy sauce of wholegrain and hot mustard, vermouth and milk. The TM7 simmers the sauce gently in the mixing bowl, giving a silky consistency without any splitting or constant stirring.

About this recipe

Pork tenderloin with mustard sauce Thermomix TM7 style brings a French bistro classic straight to your kitchen machine. Searching for a quick weeknight dinner recipe that feels restaurant-worthy? This all-in-one kitchen machine builds the sauce in a single bowl: vermouth, milk, onions, wholegrain and hot mustard are simmered together with homemade chicken stock paste until the flavours meld into a creamy, gently pungent sauce. Sliced pork tenderloin and button mushrooms finish it off, making an elegant main course without multiple pans on the hob. The milk-based sauce stays silky because the TM7 maintains a constant, moderate heat while stirring slowly, something that is notoriously tricky on a stovetop. Serve this mustard sauce recipe over fluffy mashed potatoes, rice or fresh tagliatelle, with a green salad on the side. It is an ideal choice when you want to impress guests with minimal effort.

Preparation tips

  • Slice the pork tenderloin evenly thick so every medallion cooks at the same rate; pat the slices dry first so they sear nicely in the pan while the sauce simmers in the mixing bowl.
  • Taste the sauce before serving and adjust the mustard balance: a little extra wholegrain mustard adds texture, while a teaspoon of hot mustard sharpens the tang without overpowering the vermouth.
  • Replace the dry vermouth with white grape juice mixed with a splash of white wine vinegar for a family-friendly version, and use double cream instead of milk for a richer, more indulgent sauce.

Recipe variations

  • Lactose-free variation: swap the milk for lactose-free whole milk or oat cream, which keeps the mustard sauce silky while the vermouth and stock paste carry the savoury depth of the original.
  • Festive winter variation: add a handful of soaked dried porcini to the button mushrooms and finish the sauce with a spoonful of crème fraîche and chopped tarragon for a holiday-worthy version of this pork tenderloin.
