A quick and easy 15-minute dinner featuring tender shrimp, al dente pasta, and a light garlic butter sauce made with pasta water instead of heavy cream. It’s comfort food reimagined—soul-soothing and delicious without the guilt.

Ingredients

Scale
  • 8 ounces spaghetti or linguine
  • Salt, for the pasta water
  • 1 pound large shrimp, peeled and deveined (2125 count)
  • 2 tablespoons unsalted butter, divided
  • 4 cloves garlic, minced
  • 1/4 teaspoon red pepper flakes (optional)
  • Juice of 1 lemon (about 2 tablespoons)
  • 1/4 cup reserved pasta water
  • Salt and black pepper, to taste
  • 2 tablespoons fresh parsley, chopped
  • 1/4 cup grated Parmesan cheese (optional, for serving)

Instructions

  1. Start the pasta water. Fill your large pot with water, add a generous pinch of salt (about 1 tablespoon), and bring it to a rolling boil over high heat. While you’re waiting, prep your other ingredients.
  2. Prep the shrimp. Pat the shrimp dry with paper towels—this is important for getting a good sear. Season them lightly with salt and pepper. If they’re frozen, make sure they’re fully thawed and patted dry.
  3. Cook the pasta. Once the water is boiling, add the spaghetti and cook according to package directions until al dente (usually 8-10 minutes). Before draining, reserve 1 cup of pasta water—you’ll need about 1/4 cup for the sauce, but having extra is always a good idea. Drain the pasta and set it aside.
  4. Start the sauce. While the pasta cooks, heat your large skillet over medium-high heat. Add 1 tablespoon of butter and let it melt until it’s foaming but not browning. Add the shrimp in a single layer—don’t crowd the pan; work in batches if needed. Cook for 2 minutes per side, until they’re pink and opaque. The shrimp should have a nice golden sear on the outside. Transfer them to a plate and set aside.
  5. Build the flavor. Reduce the heat to medium. Add the remaining 1 tablespoon of butter to the same skillet. Once melted, add the minced garlic and red pepper flakes (if using). Cook for about 30 seconds, stirring constantly, until the garlic is fragrant but not browned. Burnt garlic is bitter garlic, so keep an eye on it.
  6. Create the sauce. Pour in the lemon juice and 1/4 cup of the reserved pasta water. Use a wooden spoon to scrape up any brown bits from the bottom of the pan—that’s flavor right there. Let it simmer for about 1 minute, until it thickens slightly. The sauce should look silky and emulsified.
  7. Bring it all together. Add the cooked pasta and shrimp back to the skillet. Toss everything together with tongs until the pasta is evenly coated in the sauce. If it looks dry, add a splash more pasta water—the sauce should cling to the pasta, not pool at the bottom.
  8. Finish and serve. Taste and adjust seasoning with salt and pepper. Sprinkle with fresh parsley and Parmesan cheese if using. Serve immediately while it’s hot and the shrimp are still tender.

Notes

Don’t skip drying the shrimp—wet shrimp steam instead of sear. Use the pasta water trick to create a silky sauce without heavy cream. Watch your heat to avoid burning the garlic. Cook pasta to al dente since it will cook further in the sauce. Season in layers for best flavor. If the sauce looks broken, add a tiny splash of cold water and toss vigorously. Reheat leftovers in a skillet with a splash of water or broth, not the microwave.
