**Melt the butter**:
In a large skillet, melt the butter over medium heat. Add the minced garlic and sauté for 1–2 minutes, until fragrant.
**Add the cream**:
Pour in the heavy cream, whisking continuously to combine. Bring to a gentle simmer.
**Incorporate the cheese**:
Stir in the Parmesan cheese, whisking until it melts and the sauce is smooth and creamy.
**Enhance the flavor**:
If using, whisk in the tomato paste for a hint of tanginess. Add the dried basil or thyme and stir to combine.
**Season the sauce**:
Taste and adjust seasoning with salt, pepper, and red pepper flakes if desired.
**Combine with ravioli**:
Toss cooked ravioli gently in the sauce until coated. Serve immediately with extra Parmesan and fresh herbs for garnish.
