How to Make Cajun Alfredo Sauce

Follow these simple steps to make a smooth, creamy Cajun Alfredo Sauce every single time.

1. Melt the butter
   Heat a medium saucepan over medium heat. Add the butter and let it melt completely, swirling the pan gently.
2. Sauté the garlic
   Add the minced garlic and cook for about 30 seconds, just until fragrant. Stir constantly and avoid browning the garlic.
3. Add the cream and milk
   Pour in the heavy cream and whole milk. Stir well and bring the mixture to a gentle simmer over medium-low heat. Do not let it boil.
4. Season the sauce
   Sprinkle in the Cajun seasoning, paprika (if using), and black pepper. Whisk until fully combined and smooth.
5. Thicken gently
   Let the sauce simmer for 4–6 minutes, stirring often, until it slightly thickens and coats the back of a spoon.
6. Add the Parmesan cheese
   Lower the heat and slowly whisk in the grated Parmesan cheese. Stir until the cheese melts completely and the sauce turns silky and creamy.
7. Taste and adjust
   Taste the Cajun Alfredo Sauce and adjust salt or spice as needed. Remove from heat once the sauce reaches your desired thickness.

Tip: If the sauce becomes too thick, whisk in 1–2 tablespoons (15–30 ml) of warm milk until smooth.

TIPS & VARIATIONS

These simple tips help you customize your Cajun Alfredo Sauce and make it perfect every time.

Cooking Tips

• Keep the heat on medium-low to prevent the cream from separating.
• Use freshly grated Parmesan for the smoothest texture and best flavor.
• Stir constantly once the cheese goes in to avoid clumps.

Flavor Variations

• Make it spicier by adding extra Cajun seasoning or a pinch of cayenne pepper.
• Make it milder by reducing the Cajun seasoning and adding a little more cream.
• Add smoked paprika for a deeper, slightly smoky flavor.

Ingredient Swaps
