Quick Answer

Port Wine Plum Filet Mignon sears and roasts filets, then finishes them with a jammy pan sauce of fresh plums, ruby port, and thyme.

Jump to Recipe

Ruby port and ripe plums make a sauce that's deep, wine-dark, and just jammy enough to feel luxurious. Spooned over a tender filet, it's the kind of thing you'd expect at a white-tablecloth restaurant, built in a skillet in under 40 minutes.

Sear the filets, roast them to temperature, then build the sauce while they rest. Let the plums break down into the port so the sauce turns silky, and finish with butter for that glossy, professional sheen.

Ingredients

  • 2 filet mignon steaks, 7–8 ounces each
  • 1 teaspoon kosher salt
  • ½ teaspoon black pepper
  • 1 tablespoon neutral oil
  • 2 ripe red plums, diced
  • ⅓ cup ruby port
  • ½ cup beef stock
  • 1 tablespoon balsamic vinegar
  • 1 small shallot, minced
  • 1 teaspoon fresh thyme leaves
  • 1 tablespoon unsalted butter

Instructions

  1. 1Season and sear the filets for 3 minutes per side.
  2. 2Transfer to a 425°F oven for 4–7 minutes, until 125–135°F. Rest for 8 minutes.
  3. 3Cook the shallot in the skillet for 1 minute.
  4. 4Add the plums, port, stock, balsamic, and thyme. Simmer for 6–8 minutes.
  5. 5Whisk in the butter and spoon the sauce over the filets.

Pro Tips

  • Use ripe, soft plums — they melt into the sauce. Firm, underripe ones stay chunky and don't release their sweetness.
  • Reduce the port and stock until the sauce lightly coats a spoon before adding butter, so it clings to the steak.
  • Rest the filets fully before saucing; cutting a lean, tender cut too early costs you all its juice.

Substitutions

ruby port → dry red wine plus 1 teaspoon sugar Port is sweeter and richer; the sugar helps a dry red stand in.
red plums → pluots, black plums, or halved fresh cherries Any soft stone fruit works; adjust sugar to taste.
filet mignon → thick-cut top sirloin or strip steak Both suit the pan sauce; adjust cook time to the cut.

Storage Instructions

Store leftover filet and sauce in the refrigerator for up to 3 days. Reheat gently over low heat with a splash of stock to loosen the sauce.

Make Ahead

The plum port sauce can be made a day ahead and rewarmed; whisk in fresh butter before serving. Cook the filets fresh.
