8 to 10 Serves

Juicy pork tenderloin is filled with sauteed mushrooms and spinach, then wrapped in store-bought puff pastry lined with a layer of prosciutto. The resulting dish is a true showstopper, inside and out--it's just the thing for a holiday meal. Serve with mustard-cream sauce, Peppery Greens with Meyer-Lemon Dressing, and Rutabaga-Sweet Potato Mash with Garlic and Sage.


  • ¼ cup extra-virgin olive oil

  • 1 small onion, chopped (1 cup)

  • 12 ounces mixed mushrooms, such as oyster, shiitake, and cremini, chopped (5 cups)

  • 1 tablespoon fresh thyme leaves

  • Kosher salt and freshly ground pepper

  • 10 ounces frozen chopped spinach, thawed, drained, and squeezed dry

  • 2 tablespoons apple-cider vinegar

  • cup heavy cream

  • 2 pork tenderloins (each about 1 pound)

  • 1 sheet frozen all-butter puff pastry, such as Dufour, thawed

  • Unbleached all-purpose flour, for dusting

  • 4 ounces thinly sliced prosciutto

  • 1 large egg

  • 3 tablespoons Dijon mustard


  1. Heat oil in a large skillet over medium-high. Add onion, mushrooms, and thyme; season with salt. Cook, stirring occasionally, until mushrooms are browned, 10 to 12 minutes. Add spinach; cook 2 minutes more. Add vinegar and 1/3 cup cream. Cook, scraping browned bits from bottom of skillet, 1 minute. Let cool completely.

  2. Preheat oven to 425 degrees. Cut a slit down length of each tenderloin, deep enough to reach center, and season with salt. Pack mushroom mixture evenly into slits, then reshape tenderloins into logs with your hands, enclosing filling as much as possible.

  3. Unfold pastry on a lightly floured work surface. Roll out to an approximately 13-inch square; cut in half. Starting at one short end of each piece, score diagonal lines, 1 inch apart, with a sharp knife or pizza wheel (do not cut all the way through). Score in other direction, creating a crosshatch pattern. Transfer both doughs to a parchment-lined rimmed baking sheet, scored-sides down (if they become too soft, chill briefly). Divide prosciutto evenly between doughs, overlapping to fit and leaving 1-inch borders of dough. Center a tenderloin on top of each dough, stuffed-sides down. Whisk egg with 1 teaspoon water; brush borders with egg wash. Lift long sides of each dough up and over pork, stretching slightly as necessary until edges meet; pinch edges to seal. Fold short sides up over pork and flip so seams face down. Brush all over with egg wash; cut a few 1-inch vents in tops. Refrigerate 30 minutes.

  4. Bake until pastry is puffed and golden brown and a thermometer inserted into centers of pork registers 140 degrees, 20 to 25 minutes. Transfer Wellingtons to a wire rack; let cool 15 minutes. Meanwhile, stir together mustard, remaining 1/3 cup cream, and 2 tablespoons water; season with salt and pepper. Slice Wellingtons into 2-inch rounds and serve with mustard sauce.

Cook's Notes

This entree can be prepared through step 3 and refrigerated for up to one day, or frozen until firm, transferred to a freezer bag, and stored for up to a month. (If cooking from frozen, brush with more egg wash and add 15 to 20 minutes to the bake time.)
