Servings: 4

Ingredients

  • 1 Pound fettuccine dried or fresh
  • 4 Tablespoons butter
  • 2 Tablespoons chili crisp
  • 1 Clove garlic large, finely minced
  • 1 Cup heavy cream
  • ½ Teaspoon salt
  • ¼ Teaspoon black pepper
  • ¾ Cup Parmesan finely grated, plus more for serving

Optional Garnish

  • 1 green onion freshly chopped

Instructions

Cook the Fettuccine

  • Bring a large pot of salted water to a boil.
  • Cook fettuccine until al dente according to package directions, reserving ¼ Cup of the starchy pasta water.

Make the Alfredo Sauce

  • Melt 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 1 minute or until fragrant.
  • Whisk in cream, salt, and pepper until combined.
  • Keep it warm over low heat.

Combine the Pasta and Sauce

  • Use tongs to transfer fettuccine to the pan, along with pasta water.
  • Toss noodles in the cream sauce.
  • Add 2 Tablespoons of pasta cooking water and the Parmesan to the pan.
  • Toss noodles until coated in sauce, adding more pasta water if needed.
  • Divide among warmed serving plates or bowls.

Add Toppings

  • Top with more Parmesan and the remaining Tablespoon of chili crisp.
  • Serve immediately, garnished with chopped green onions, if liked.

Notes

Grate the cheese finely: Very fine Parmesan melts into the cream mixture more easily, so the sauce stays smooth instead of stringy.
Reserve extra pasta water: Keep more pasta cooking water than you think you need so you can adjust the sauce texture right at the end.
Keep the heat low: Hold the cream sauce over a low heat so it does not bubble or boil. This helps prevent splitting.
Finish at the table: Bring extra chili crisp and Parmesan to the table so everyone can adjust the spice and richness on their own plate.
