1. In a large saucepan, melt the butter over medium heat. Add the minced garlic and sauté until fragrant, about 1 minute, stirring continuously to prevent burning.
2. Pour in the heavy cream, stirring gently to combine with the garlic-infused butter. Allow the mixture to come to a gentle simmer.
3. Gradually add the grated Parmesan cheese, stirring continuously until the cheese melts smoothly into the cream, creating a luscious, creamy base.
4. Sprinkle in the Cajun seasoning, smoked paprika, and cayenne pepper (if using). Stir well to incorporate the spices evenly throughout the sauce.
5. Season the sauce with salt and black pepper to taste. Continue to simmer for another 2-3 minutes, allowing the flavors to meld beautifully.
6. Remove the saucepan from the heat and let the sauce sit for a couple of minutes to thicken slightly before serving over your favorite pasta.
7. Garnish with freshly chopped parsley for a hint of color and freshness that complements the rich, creamy sauce.

One tip Mum always emphasized was to taste as you go. It’s the secret to achieving the perfect balance of flavors, much like an artist perfecting their palette.
