In a large skillet, melt the butter with the cream over low heat, allowing it to gently simmer for about 2 minutes.
Add the minced garlic, Italian herb seasoning, salt, and black pepper to the mixture. Whisk everything together for about a minute until well combined.
Gradually stir in the freshly grated Parmesan cheese, continuing to whisk until the cheese is fully melted and the sauce is smooth.
Serve the Alfredo sauce immediately, paired with your favorite pasta or dish.
