Instructions

  1. Bring a large pot of salted water to a boil. Zest and quarter the lemon. Finely chop the garlic and parsley. Rinse the shrimp and scallops, then pat dry. In a medium bowl, toss the shrimp and scallops with lemon zest, half the garlic, a drizzle of olive oil and a pinch of chili flakes. Season with salt and pepper.
  2. Add spaghetti to the boiling water and cook until al dente, 9-11 minutes. Reserve ½ cup pasta water, then drain.
  3. Heat a large pan over high heat. Add the shrimp and scallop mixture in an even layer. Cook, stirring once, until opaque and cooked through, 2-3 minutes. Stir in 1 tablespoon butter until melted. Transfer to a bowl.
  4. In the same pan, melt 2 tablespoons butter over medium heat. Add the remaining garlic and cook until fragrant, about 30 seconds. Stir in the chicken stock concentrates and ¼ cup reserved pasta water. Simmer until slightly reduced, 1-2 minutes.
  5. Add the drained spaghetti, cooked seafood, garlic herb butter, half the parsley and half the Parmesan. Toss to coat, adding more pasta water as needed for a smooth sauce. Remove from heat and squeeze in lemon juice. Season with salt and pepper.
  6. Divide among bowls. Top with remaining parsley, Parmesan and chili flakes. Serve with lemon wedges.

Recipe Tips

Pat the seafood very dry before cooking to ensure a good sear.

If the sauce seems clumpy, keep stirring and add a splash of pasta water until smooth.

Adjust the chili flakes to your heat preference.
