Cooking Guide

What pasta works best for this dish?

Ditalini pasta is ideal here due to its small tube shape, which holds the creamy sauce well and complements the texture of caramelized onions.

How do I achieve deeply caramelized onions?

Cook sliced onions slowly over medium heat with butter, olive oil, a pinch of sugar, and salt, stirring often for 25–30 minutes until they become golden brown and rich in flavor.

Can I make this dish gluten-free?

Yes, simply substitute the ditalini pasta and all-purpose flour with gluten-free versions to accommodate dietary needs without sacrificing taste.

What type of broth enhances the flavor?

Vegetable broth works well for a vegetarian option, while beef broth adds richness for a non-vegetarian variation.

How is the creamy sauce thickened?

A mixture of flour and broth is simmered, then combined with heavy cream, fresh thyme, and Dijon mustard to create a smooth, velvety sauce coating the pasta.

What cheese options complement this dish?

Gruyère and Parmesan cheeses provide a nutty and savory finish, but Swiss or a mozzarella-sharp cheddar mixture can also work well.
