Pork Tenderloin with Mustard-Onion Topping

This dish is a gem from the early '90s—a family recipe passed down from a German friend. It's called Schweinelende in Senfkruste and I’ve never come across anything quite like it since, and it doesn’t seem to exist online either. In fact, I couldn’t even find a photo that matched—so this one was generated by ChatGPT! It’s not exactly what it looks like, but it’s close. The real version is a bit more rustic.

Ingredients for four servings:

  • 600 g pork tenderloin
  • 16 thin slices of bacon or pancetta
  • 1 large onion
  • A splash of white wine vinegar
  • 200 g crème fraîche
  • 5 teaspoons mustard
  • Salt and pepper

Instructions:

Finely dice the onion and sauté in a butter until soft and translucent. Deglaze with a splash of white wine vinegar and stir until the liquid evaporates.

Add the mustard and crème fraîche, stir to combine, and simmer briefly until slightly thickened. Let the mixture cool a bit.

Cut the pork tenderloin into 16 medallions and season with salt and pepper.

Lay out the bacon slices on a parchment-lined baking sheet. Place one medallion on each slice, then top each with a spoonful of the mustard-onion mixture.

Bake in a preheated oven at 425°F for about 15 minutes, until the pork is cooked through and the topping is golden.
