Common Recipe Questions

How do I caramelize onions perfectly?

Cook thinly sliced onions slowly over medium heat with butter and oil, stirring frequently, until they turn golden brown and deeply caramelized, usually 25-30 minutes.

Can I use a different pasta than ditalini?

Yes, small tubular or short pasta shapes like elbow or small shells work well to hold the creamy sauce.

How can I make this dish gluten-free?

Use gluten-free pasta and substitute all-purpose flour with a gluten-free alternative to maintain the sauce’s texture.

What can I substitute for Gruyère cheese?

Swiss cheese or a mix of mozzarella and sharp cheddar provide a similar creamy and savory profile.

Is it better to use vegetable or beef broth?

Vegetable broth keeps the dish vegetarian and light, while beef broth adds a richer, deeper flavor for non-vegetarian options.
