Spaghetti with Pistachio Pesto and Salmon

Instructions

  1. 1

    Bring a pot of water to boil and blanch shelled pistachios for 1 minute to soften the skin, then drain on a kitchen towel and rub gently to remove skins while still warm.

  2. 2

    Transfer pistachios to a blender with olive oil, grated Grana Padano, basil leaves, half a garlic clove, and grated lemon zest. Pulse briefly, then add water, salt, and pepper. Blend until smooth and creamy.

  3. 3

    Cut salmon into cubes. Heat olive oil in a skillet and sear the salmon until golden. Season with salt and set aside.

  4. 4

    Cook spaghetti in abundant salted water. Loosen the pesto with lemon juice and pasta water until creamy.

  5. 5

    Drain pasta into the skillet with salmon drippings. Remove from heat, add pesto, and toss gently. Fold in salmon carefully to avoid breaking.

  6. 6

    Plate and finish with lemon zest and black pepper.

  7. 7

    Serve immediately.

Tips

Tip 1

Blanch pistachios while warm so the skin rubs off easily without drying.

Tip 2

Blend pesto until completely smooth for best texture with pasta.

Tip 3

Add pesto off heat to preserve the bright flavor and pistachio color.

Tip 4

Use pasta water to achieve creamy consistency without excess cream.

Good to Know

Storage

Pesto keeps refrigerated 3 days in airtight container. Do not store cooked salmon in pesto as texture deteriorates.

Make Ahead

Prepare pesto up to 3 days ahead. Cook salmon and pasta fresh for best texture.

Serve With

Serve immediately on warm plates. Pair with crisp white wine such as Vermentino or Pinot Grigio.
