Ingredients Equipment Method Notes

Ingredients
  

  • 12 ounces fettuccine pasta
  • 1 pound large shrimp, peeled and deveined
  • 4 tablespoons unsalted butter, divided
  • 4 cloves garlic, minced
  • 2 cups heavy cream
  • 1 1/2 cups freshly grated Parmesan cheese
  • Kosher salt, to taste
  • Freshly cracked black pepper, to taste
  • Fresh parsley or basil, chopped for garnish

Equipment

  • Large pot
  • Colander
  • Large skillet or sauté pan
  • Tongs
  • Measuring cups and spoons
  • Cutting board
  • Chef's knife
  • Microplane or box grater
  • Paper towels
  • Mixing bowls
  • Whisk

Method
 

  1. Bring a large pot of well-salted water to a rolling boil. Cook the fettuccine according to package directions until al dente. Before draining, reserve 1 cup of the starchy pasta water. Drain the pasta and do not rinse.
  2. While the pasta cooks, pat the shrimp very dry with paper towels. Season lightly with salt and pepper.
  3. In a large skillet over medium-high heat, melt 1 tablespoon of the butter. Add the shrimp in a single layer and cook for 1-2 minutes per side until pink, opaque, and lightly golden. Immediately transfer the shrimp to a plate and set aside.
  4. Reduce the heat to medium. Add the remaining 3 tablespoons of butter to the same skillet. Once melted, add the minced garlic and cook for 30-60 seconds until fragrant but not browned.
  5. Pour in the heavy cream, stirring to combine with the butter and garlic. Bring to a gentle simmer and let it cook for 3-4 minutes to reduce and thicken slightly.
  6. Reduce the heat to low. Gradually whisk in the freshly grated Parmesan cheese, stirring constantly until the cheese is fully melted and the sauce is smooth.
  7. Add the drained, hot pasta to the skillet with the sauce. Using tongs, toss vigorously to coat every strand. If the sauce is too thick, add a splash of the reserved pasta water to reach your desired consistency.
  8. Add the cooked shrimp and any accumulated juices back to the skillet. Gently toss everything to combine and warm the shrimp through. Taste and adjust seasoning with salt and pepper.
  9. Serve immediately, garnished with fresh parsley or basil.

Notes

For the best texture, grate your own Parmesan cheese from a block; pre-shredded cheese contains anti-caking agents that can make the sauce grainy. Do not rush the gentle simmering of the cream, as it cooks out the raw dairy taste and helps thicken the sauce. The reserved starchy pasta water is essential for adjusting the sauce's consistency and helping it cling to the pasta. For variations, try adding a teaspoon of red pepper flakes with the garlic, stirring in fresh spinach at the end, or brightening the dish with lemon zest. This dish is best served immediately. Store leftovers in an airtight container in the refrigerator for up to 2 days; reheating gently with a splash of cream or milk is recommended.
