Instructions

  1. Bring a large pot of salted water to a boil. Add the spaghetti and cook until al dente, about 9-11 minutes. Reserve 1/2 cup of pasta cooking water, then drain the spaghetti.
  2. While the pasta cooks, wash and dry the produce. Trim the zucchini, halve it lengthwise and cut crosswise into 1/4-inch half-moons. Thinly slice the chili pepper. Rinse the shrimp under cold water and pat very dry with paper towels.
  3. Heat a large drizzle of olive oil in a large pan over medium-high heat. Add the zucchini and as much sliced chili as you like. Cook, stirring occasionally, until the zucchini is lightly browned, about 2-3 minutes.
  4. Push the zucchini mixture to one side of the pan and add another drizzle of olive oil to the empty side. Add the shrimp and cook, stirring occasionally, until opaque and cooked through, 3-4 minutes.
  5. Add the drained spaghetti, garlic herb butter, half of the Parmesan (reserve the rest for serving) and 1/4 cup of the reserved pasta cooking water to the pan. Season generously with salt and pepper. Toss everything together until well combined. If the pasta seems dry, add more reserved cooking water a splash at a time until the sauce coats the pasta evenly.
  6. Divide the pasta among bowls. Top with the remaining Parmesan and a drizzle of olive oil. Garnish with any remaining sliced chili to taste and serve immediately.

Recipe Tips

For a milder dish, use only a small slice of chili pepper and remove the seeds.

Make sure to pat the shrimp very dry before cooking to ensure they sear properly.

Reserve extra pasta water than you think you’ll need; it’s the key to a silky sauce.

FAQ
