Ingredients

  • 1 tablespoon unsalted butter
  • ½ tablespoon Dijon mustard
  • zest of 1 small lemon about ¾ teaspoon
  • ¾ teaspoon kosher salt divided
  • ½ teaspoon ground black pepper divided
  • ½ teaspoon dried thyme
  • 2 teaspoons extra virgin olive oil
  • 4 cups fresh baby spinach
  • 2 cloves garlic minced
  • 2 tablespoons freshly grated Parmesan cheese
  • 1 large egg yolk plus 1 teaspoon water
  • 1 sheet frozen puff pastry thawed in the refrigerator
  • 2, 6- ounce salmon fillets skin removed

Instructions

    Cup of Yum
  1. Place a rack in the center of your oven and preheat the oven to 400 degrees F. Line a rimmed baking sheet with parchment paper. Leave the salmon in the refrigerator.
  2. Melt the butter in a small bowl or saucepan. Stir in the Dijon, lemon zest, ¼ teaspoon kosher salt, and ¼ teaspoon black pepper. Set aside.
  3. Heat the oil in a large, nonstick skillet. Add the spinach in large handfuls, cooking until it wilts, about 1 minute. Stir in the garlic, thyme, remaining 1/2 teaspoon salt and ¼ teaspoon pepper. Stir in the Parmesan. Remove from the heat and let cool.
  4. In a small bowl, lightly beat the egg yolk with 1 teaspoon water to act as an egg wash. Set aside.
  5. Place the puff pastry on a lightly floured work surface and roll it into a 12x14-inch rectangle. With a sharp knife, cut the puff pastry in half crosswise so you are left with two rectangles that are 12 x 7 inches each.
  6. Remove the salmon fillets from the refrigerator and place on a plate. Brush the tops of the fillets liberally with the butter mixture, then place each fillet, butter-side down, in the center of a piece of puff pastry. Spoon half of the cooled vegetables over the top.
  7. Fold one side of the puff pastry over the top of the fillet like a flap, so that it partially covers it, then brush the top of the flap with egg wash. Fold the next side, adhering it to the first if the flaps are large enough to touch (the egg wash should act as a “glue”), then brush its top with egg wash. Repeat until all 4 sides are folded over. It should be as if you are wrapping up the salmon like a delicious present. Don’t stress over the order of the flaps. As long as it’s well sealed and covers the salmon, you’re golden. Carefully flip the salmon over and transfer it to the prepared baking sheet, with the folded side underneath. Repeat with the second fillet.
  8. Brush the tops of the puff pastry with egg wash, then with a sharp knife, score shallow, diagonal lines in each direction in a crosshatch pattern.
  9. Bake the salmon for 20 to 25 minutes, or until the pastry turns golden brown. Let cool a few minutes on the baking sheet. Serve hot.

Notes

  • TO STORE: Place leftover salmon in an airtight storage container in the refrigerator for up to 2 days. 
  • TO REHEAT: Let the salmon come to room temperature, then reheat it in the oven at 375 degrees F for about 10 to 15 minutes until warmed through. You can rewarm this dish in the microwave in a pinch, but the oven will yield much better results. 
  • TO MAKE AHEAD AND FREEZE: I do not recommend freezing baked salmon Wellington. However, you can freeze salmon Wellington before it is baked. Prepare as directed, but do not add the egg wash. Place it on a baking sheet in the freezer until solid. Then, store in an airtight freezer-safe storage container in the freezer for up to 3 months. When you're ready to prepare it, let it sit at room temperature for 20 minutes, then add the egg wash and bake as directed. 
  • TO MAKE AHEAD: Up to 1 day in advance, you can prepare the salmon fillets and wrap them in the puff pastry. Score the puff pastry, but do not add the egg wash yet. Store it in the refrigerator. When you're ready to bake the salmon, then add the egg wash and bake as directed.
