Ingredients

For the Pasta:

12 oz (340g) spaghetti
1 tablespoon olive oil
1 teaspoon salt (for pasta water)

For the Shrimp and Sauce:

1 lb (450g) large shrimp, peeled and deveined (tails left on or off, per preference)
3 tablespoons butter
1 tablespoon olive oil
4 cloves garlic, minced
1/4 teaspoon red pepper flakes (optional, for heat)
1 cup heavy cream
3/4 cup freshly grated Parmesan cheese
1/4 cup reserved pasta water
Juice of 1/2 a small lemon
Salt and freshly cracked black pepper, to taste

For Garnish:

2 tablespoons fresh green onions, thinly sliced
Additional grated Parmesan cheese, for serving

Instructions

Cook the Spaghetti: Bring a large pot of salted water to a rolling boil. Add the olive oil (this helps prevent sticking) and the spaghetti. Cook according to the package directions until al dente (firm to the bite). Before draining, reserve about 1/2 cup of the starchy pasta water. Drain the spaghetti and set it aside.
Sear the Shrimp: While the pasta is cooking, prepare the shrimp. Pat the peeled shrimp completely dry with paper towels. Season them lightly with salt and black pepper. In a large skillet or Dutch oven, melt 1 tablespoon of the butter with the 1 tablespoon of olive oil over medium-high heat. Once hot, add the shrimp in a single layer. Cook for 2–3 minutes per side, until the shrimp are pink and opaque. Do not overcook them. Remove the shrimp from the skillet and set them aside on a plate.
Build the Sauce: Reduce the heat to medium. Add the remaining 2 tablespoons of butter to the same skillet. Once melted, add the minced garlic and the red pepper flakes (if using). Sauté for 60 seconds, until the garlic is fragrant but not browned.
Combine Cream and Cheese: Pour the heavy cream into the skillet. Stir continuously, scraping up any flavorful browned bits from the bottom of the pan. Bring the mixture to a low simmer. Let it bubble gently for 1–2 minutes until it begins to thicken slightly. Remove the skillet from the heat and stir in the grated Parmesan cheese until melted and the sauce is smooth.
Finish and Serve: Return the skillet to low heat. Add the drained spaghetti, the seared shrimp, and the fresh lemon juice to the sauce. Toss everything together gently until the pasta is evenly coated and the shrimp are heated through. If the sauce is too thick, gradually add the reserved pasta water, a tablespoon at a time, until your desired consistency is reached. Season with additional salt and pepper to taste.
Garnish and Plate: Serve the creamy shrimp spaghetti immediately in warm bowls. Garnish generously with the sliced green onions and extra grated Parmesan cheese.

Tips for Success

Don’t Overcook the Shrimp: This is the most crucial tip. Shrimp cook very quickly and will become rubbery if overcooked. Remove them from the pan as soon as they turn pink. They will finish cooking gently when added back to the sauce at the end.
Grate Your Own Parmesan: For the smoothest and creamiest sauce, buy a block of Parmesan cheese and grate it yourself. Pre-grated cheese often contains anti-caking agents that prevent it from melting smoothly.
Don’t Rinse the Pasta: After draining the spaghetti, do not rinse it. The starch on the surface of the pasta helps the creamy sauce adhere to it better.
Adjust the Heat: If you prefer a milder dish, feel free to omit the red pepper flakes. If you like it spicier, you can increase the amount or add a pinch of cayenne pepper along with the garlic.

Storage and Reheating

Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Be aware that the pasta will absorb much of the cream sauce as it sits.
Reheating: To reheat, place the spaghetti in a skillet over low heat. Add a splash of milk, cream, or chicken broth to loosen the sauce and restore its creamy consistency. Stir gently until warmed through. Reheating in the microwave can cause the sauce to break or the shrimp to become rubbery, so stovetop reheating is recommended.

Serving Suggestions

This rich and creamy pasta pairs best with lighter sides that cut through the richness. A crisp, simple green salad with a lemony vinaigrette or a side of roasted asparagus or green beans would be a perfect complement. For the beverage, a chilled Pinot Grigio or Sauvignon Blanc will balance the creamy sauce beautifully.
