In a medium saucepan, melt the butter over medium heat. Add the minced garlic and sauté for about 1 minute, until fragrant but not browned.
Pour in the heavy cream and stir to combine. Bring the mixture to a gentle simmer, then reduce the heat to low.
Gradually whisk in the grated Parmesan cheese until melted and smooth.
Stir in the Italian seasoning, and season with salt and pepper to taste.
Allow the sauce to simmer for an additional 2-3 minutes, stirring occasionally, until it thickens slightly.
Remove from heat and serve immediately over cooked ravioli. Garnish with fresh parsley before serving.
