Creamy, buttery fettuccine Alfredo gets a bold, spicy upgrade with chili crisp, garlic, and freshly grated Parmesan. Ready in about 30 minutes, this easy stovetop pasta is finished with extra chili crisp and fresh green onion for a flavorful weeknight dinner.

Ingredients

For the pasta

  • 1 pound fettuccine, dried or fresh
  • Salt, for the pasta water

For the Alfredo sauce

  • 4 tablespoons butter
  • 2 tablespoons chili crisp, divided
  • 1 large garlic clove, finely minced
  • 1 cup heavy cream
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 3/4 cup finely grated Parmesan, plus more for serving
  • 1/4 cup reserved starchy pasta water, as needed

For serving

  • 1 green onion, freshly chopped (optional)

Instructions

  1. Cook the fettuccine. Bring a large pot of salted water to a boil. Cook the fettuccine until al dente according to the package directions. Before draining, reserve 1/4 cup of the starchy pasta water.
  2. Start the sauce. While the pasta cooks, melt the butter in a large skillet or Dutch oven over medium-low heat. Add 1 tablespoon of the chili crisp and the minced garlic. Cook for about 1 minute, stirring, until fragrant.
  3. Add the cream. Whisk in the heavy cream, salt, and black pepper until combined. Keep the sauce warm over low heat; do not let it boil.
  4. Combine the pasta and sauce. Use tongs to transfer the cooked fettuccine to the pan. Add 2 tablespoons of the reserved pasta water and the Parmesan, then toss until the noodles are coated. Add more pasta water a little at a time if needed to loosen the sauce.
  5. Finish and serve. Divide the pasta among warmed plates or bowls. Top with additional Parmesan and the remaining 1 tablespoon of chili crisp. Garnish with chopped green onion, if desired, and serve immediately.

Notes

  • Reserve the pasta water before draining; its starch helps the sauce cling to the noodles.
  • For the smoothest sauce, grate Parmesan finely from a block and keep the heat low when adding it.
  • Chili crisp varies in heat and saltiness. Adjust the amount to suit your taste.
  • Serve immediately, as Alfredo sauce thickens as it cools. Add a splash of warm water or cream when reheating to loosen it.
