Cook the pasta according to package instructions.
In a large skillet, heat olive oil over medium-low heat.
Add the sliced shallots and cook, stirring regularly, until caramelized.
Incorporate minced garlic and cook for an additional minute.
Pour in the broth and cream, stirring to combine, then simmer for 3-5 minutes.
Stir in the cooked pasta and grated Parmesan, mixing until well coated.
If the sauce is too thick, add reserved pasta water slowly until desired consistency.
Taste and adjust seasoning with salt and pepper, then serve hot.
