Spicy Alfredo Sauce

Ready to spice your typical Alfredo sauce up a notch? Adding in a little cayenne pepper powder is an excellent way to start, whether it’s Fettuccine Alfredo, chicken, or another concoction. Spicy Alfredo sauce can be that simple to make.

But you don’t need to stop there – try experimenting with crushed red pepper and even hot sauce, too. A tiny dash of Sriracha or Tabasco can add a unique twist to the flavor. You could also opt for a milder warmth by choosing paprika instead of cayenne pepper powder. Choose a generically labeled or sweet paprika, not hot paprika. Or for something a little smoky, try cutting the cayenne used in your spicy Alfredo sauce with a dash or two of chipotle powder. We have a recipe for that too. There are many ways to bring life to this spicy pasta sauce.

  • 1 cup heavy cream
  • 1/2 cup salted butter
  • 1 1/2 cup Parmesan cheese grated
  • 1 clove garlic diced
  • 1/2 teaspoon cayenne pepper powder
  • 1/2 teaspoon salt
  • 1/2 teaspoon pepper


  • Over medium heat, combine the butter and garlic in a saucepan. Stir until the butter is melted and the garlic is fragrant.
  • Add the heavy cream, Parmesan cheese, and cayenne. Stir the sauce until the cheese is melted.
  • Remove the saucepan from the heat and add in the salt and pepper. Stir until combined.
  • Serve with pasta.


No cayenne pepper powder? Use 2 tablespoons of crushed red pepper instead. Want extra heat? Try a dash of hot sauce to spice things up. A dash of Sriracha will add a little more garlic flavor, while Tabasco will provide more tang. Or try swapping in a different variety of chili powder (paprika or chipotle both can work).

I made this as written. We liked this recipe, but next time will change it slightly. It tasted too strongly of parmesan cheese, and the butter was “swimming” in this, so I will reduce both, probably by 1/2.
