Equipment

  • Large deep skillet or Dutch oven
  • Tongs or wooden spoon
  • Microplane or fine grater
  • Measuring Cups and Spoons
  • Knife and cutting board

Ingredients
  

Base Dish:

  • 12 oz spaghetti
  • 1 lb salmon fillets (skin-on or skinless)
  • 2 tbsp olive oil
  • 4 cloves garlic, minced
  • 1 tsp red pepper flakes (optional)
  • Zest and juice of 1 large lemon
  • 4 cups low-sodium chicken or vegetable broth
  • Salt and pepper, to taste

Optional Add-ins:

  • 1 cup cherry tomatoes, halved
  • 2 cups baby spinach
  • ¼ cup grated Parmesan cheese
  • 2 tbsp mascarpone or cream
  • Fresh parsley or basil, chopped (for garnish)

Instructions
 

  • Prep Salmon: Season fillets with salt, pepper, and half the lemon zest. Set aside.
  • Sauté Base: In a large pot, heat olive oil over medium. Add garlic and red pepper flakes; sauté for 30 seconds until fragrant.
  • Add Pasta & Broth: Add spaghetti, broth, lemon juice, and remaining zest. Bring to a boil.
  • Poach Salmon: Nestle salmon fillets on top. Scatter cherry tomatoes if using. Cover and simmer for 10–12 minutes until pasta is al dente and salmon is cooked.
  • Combine: Remove lid, flake salmon gently with tongs. Stir in spinach until wilted. Add mascarpone or Parmesan off heat for creaminess.
  • Serve: Adjust seasoning. Garnish with herbs and extra lemon zest or cheese. Serve in warm bowls.

Notes

  • Use fresh lemon zest for best aroma.
  • Stir pasta occasionally to prevent sticking.
  • Add spinach at the end to preserve color.
  • For dairy-free: skip mascarpone or use oat/cashew cream.
  • Avoid freezing if using mascarpone—it may separate.
  • Great with linguine, tagliatelle, or bucatini as pasta swaps.
