Gather your ingredients: unsalted butter, minced garlic, heavy cream, grated Parmesan cheese, Italian seasoning, salt, pepper, and fresh parsley.
Melt the unsalted butter in a large skillet over medium heat.
Add the minced garlic to the skillet and sauté for 1 minute, stirring frequently.
Sprinkle in the Italian seasoning and stir.
Pour in the heavy cream and bring to a gentle simmer while stirring frequently.
Gradually whisk in the grated Parmesan cheese until it melts and the sauce becomes smooth.
Once the sauce has thickened slightly, combine it with your cooked ravioli and toss until well coated.
Remove from heat and garnish with fresh parsley before serving.
