I love this Cajun Alfredo Sauce as is, but here are a few ideas for variations:

- Add Garlic: Add some minced garlic to the sauce for extra flavor.
- Different Cheese: Try using Asiago or Romano cheese instead of Parmesan.

How to Make Cajun Alfredo Sauce
Let me show you how easy it is to make this Creamy Cajun Alfredo Sauce:
Melt Butter
- I melt the butter in a large skillet over low heat. I want it melted and just starting to froth (you’ll see white bubbles on top).
Add Cream and Seasoning
- I stir in the heavy cream and Cajun seasoning. I add salt if needed (depending on whether my Cajun seasoning blend already contains salt).
- I bring the mixture to a simmer and cook on low for 5 to 6 minutes, stirring occasionally.
Add Cheese and Lemon Zest
- I remove the pan from the heat and add the lemon zest.
- I gradually add the freshly grated Parmesan cheese, stirring until the cheese is completely melted and the sauce is smooth. I make sure to add the cheese gradually to prevent it from clumping.
- Salt to taste
Serve
- Add pasta to the pan
Tips and Tricks for the BEST Alfredo Sauce
Here are my secrets for making this sauce truly exceptional:
- Use Freshly Grated Parmesan: Freshly grated Parmesan cheese melts better and has a much more intense flavor than pre-grated.
- Low Heat: Cook the sauce over low heat to prevent the cream from separating or scorching.
- Whisk Constantly: Whisking constantly while adding the cheese helps to create a smooth and creamy sauce.
- Adjust Consistency: If the sauce is too thick, add a little more cream or pasta water. If it’s too thin, simmer it for a few more minutes.
How to Serve
This Cajun Alfredo Sauce is delicious served with:
- Pasta: Toss it with your favorite pasta, like fettuccine, linguine, or penne.
- Chicken: Serve it over grilled or pan-seared chicken breasts.
- Shrimp: It’s amazing with grilled or sautéed shrimp.
- Vegetables: Drizzle it over roasted vegetables, like broccoli, asparagus, or cauliflower.
- Dipping Sauce: Use it as a dipping sauce for breadsticks, garlic bread, or vegetables.
Make Ahead and Storage
You can make this sauce ahead of time and store it in the refrigerator for up to 3 days. Reheat gently over low heat, stirring constantly.

Ingredients
Scale
For the Cajun Alfredo Sauce:
- 1/2 cup (1 stick) unsalted butter
- 1 1/2 cups heavy cream
- 2 tablespoons Cajun seasoning (homemade or store-bought, see notes for homemade recipe)
- 1/2 teaspoon kosher salt (omit if your Cajun seasoning blend already contains salt)

- 1 teaspoon ground mustard (dry mustard powder)
- 1 teaspoon dried oregano
- 1 teaspoon dried thyme
- 1 teaspoon cayenne pepper (adjust to your spice preference)
- 1/2 teaspoon dried basil
Instructions
- Melt Butter: Melt the butter in a large skillet over low heat. Cook until the butter is melted and begins to froth (small white bubbles appear on the surface).
- Add Cream and Seasoning: Stir in the heavy cream and Cajun seasoning. If your Cajun seasoning blend does not contain salt, add 1/2 teaspoon of kosher salt.
- Simmer: Bring the mixture to a gentle simmer. Cook over low heat for 5-6 minutes, stirring occasionally. Do not boil.
- Add Lemon Zest: Remove the skillet from the heat. Stir in the lemon zest.

Notes
- Cajun Seasoning: You can use store-bought Cajun seasoning or make your own. If making your own, combine all the ingredients for the Homemade Cajun Seasoning in a small bowl and mix well. Store any leftover seasoning in an airtight container.
- Parmesan Cheese: Use freshly grated Parmesan cheese for the best flavor and melting quality. Pre-grated Parmesan cheese often contains cellulose, which can prevent it from melting smoothly. Do not use the powdery “Parmesan” from a can.
- Heat Level: Adjust the amount of cayenne pepper in the homemade Cajun seasoning to control the spiciness of the sauce.
- Consistency: If the sauce is too thick, add a little more heavy cream or a splash of pasta cooking water to thin it out.
