Whip up this creamy, flavorful Cajun Alfredo sauce in minutes! Rich and delicious, it’s perfect for pairing with pasta, chicken, or seafood for an easy, restaurant-quality meal or quick weeknight dinner.
In a large saucepot over medium-low heat, melt the butter.
Add the diced shallot and minced garlic. Sauté for 1-2 minutes until fragrant.
Whisk in the heavy cream, Parmesan cheese, and Cajun seasoning. Stir until well combined and let it simmer for 5-8 minutes. The sauce will thicken as it cools.
Add chopped parsley or chives and a squeeze of fresh lemon juice, if desired. Serve sauce with pasta or drizzled over chicken and seafood.
Notes
For a pasta sauce: If the sauce is too thick, stir in some reserved pasta water a little at a time. The starchy water will help thin the sauce while maintaining its creamy texture.
If using store-bought Cajun seasoning, it will probably contain salt and pepper. Check for the amount of sodium, taste and season with more salt and pepper if necessary.
Adjust the amount of Cajun seasoning to suit your preferred spice level. Begin with a teaspoon and increase gradually if you want a spicier flavor. For an extra touch of heat, try adding a pinch of cayenne pepper.
