🌿 Watercress Pesto–Crusted Salmon

Watercress pesto–crusted salmon is a fresh, flavorful way to elevate an everyday salmon dinner. Tender, flaky salmon is topped with a vibrant pesto made from peppery watercress, herbs, garlic, and Parmesan, creating a bright herb crust that complements the richness of the fish.
Simple to prepare yet elegant on the plate, this dish is perfect for weeknight meals or casual entertaining. The watercress pesto adds a clean, slightly peppery finish that keeps the salmon light, balanced, and deeply satisfying.

Equipment

  • Food processor or blender
  • Baking sheet
  • Parchment paper or foil
  • Measuring cups and spoons
  • Sharp knife
  • Cutting board
  • Fish spatula (optional but helpful)

Ingredients

Salmon

  • 4 salmon fillets 5–6 oz each, skin-on or skinless
  • Salt and freshly cracked black pepper
  • 1 tbsp olive oil

Watercress Pesto

  • 2 packed cups fresh watercress stems trimmed
  • ¼ cup fresh basil optional but lovely
  • â…“ cup grated Parmesan cheese
  • ¼ cup toasted pine nuts or walnuts
  • 1 small garlic clove
  • Zest of 1 lemon
  • â…“ cup olive oil
  • Salt to taste

Optional Finish

  • Lemon wedges
  • Extra pesto for serving

Instructions

Make the watercress pesto

  • In a food processor, combine watercress, basil, Parmesan, nuts, garlic, and lemon zest. Pulse until finely chopped. With the motor running, drizzle in olive oil until a thick, spreadable pesto forms. Season to taste.

Prep the salmon

  • Pat salmon dry and season lightly with salt and pepper. Place on a lined baking sheet and drizzle with olive oil.

Crust with pesto

  • Spoon a generous layer of watercress pesto over the top of each fillet, spreading evenly to create a thick crust.

Bake

  • Bake at 400°F (205°C) for 12–15 minutes, until salmon flakes easily and the pesto is lightly set.

Serve

  • Finish with a squeeze of lemon and extra pesto if desired.

Notes

  • Watercress flavor: Watercress has a naturally peppery bite; combining it with basil helps balance the pesto without overpowering the salmon.
  • Pesto texture: The pesto should be thick enough to stay on the fish. If it’s too loose, add a bit more cheese or nuts.
  • Salmon doneness: Salmon is done when it flakes easily and reaches an internal temperature of 125–130°F for medium.
  • Nut swaps: Pine nuts, walnuts, almonds, or even sunflower seeds work well in the pesto.
  • Make-ahead tip: The watercress pesto can be made up to 2 days ahead and stored in the refrigerator with a thin layer of olive oil on top.
  • Broiler option: For a lightly golden crust, broil for the last 1–2 minutes, watching closely to prevent burning.
  • Serving ideas: Pairs beautifully with roasted potatoes, asparagus, or a simple lemony salad.
