Recipe FAQ

How do I caramelize onions properly?

Cook sliced onions slowly over medium heat with butter and oil, stirring occasionally until they turn deep golden brown and sweet, around 25-30 minutes.

Can I use a different type of pasta?

Yes, small pasta shapes like ditalini are ideal, but you can substitute with other short pasta like elbow macaroni or small shells.

How do I achieve a creamy sauce without curdling?

Simmer the cream gently and add it towards the end of cooking, avoiding high heat, to keep the sauce smooth and creamy.

What can I use instead of Gruyère cheese?

Swiss cheese or a blend of mozzarella and sharp cheddar work well to create a melty, flavorful topping.

Is it possible to make this gluten-free?

Yes, use gluten-free pasta and substitute all-purpose flour with a gluten-free alternative to maintain the sauce’s consistency.
