FAQs

• Why caramelize onions slowly?

Caramelizing onions slowly breaks down their natural sugars, creating a deep, rich, sweet flavor that adds complexity to the pasta dish. Low and slow cooking develops rich brown color and intense taste without burning.

• Can I use different types of cheese?

While mozzarella and parmesan work best for this recipe, you can substitute with gruyère or swiss cheese for a more traditional French onion flavor. Just ensure the cheese melts well and complements the caramelized onions.

• What makes this a one-pot recipe?

The technique allows pasta to cook directly in the broth with caramelized onions, absorbing flavors while creating a creamy sauce simultaneously. This method reduces cleanup and creates a more flavorful pasta dish with minimal effort.
