Recipe FAQs

What cut of beef works best?

Chuck roast is ideal for its marbling and tenderness after slow cooking.

Can I substitute the cheese?

How do I get the onions deeply caramelized?

Cooking the onions slowly over medium heat with butter for about 25 minutes develops their sweet, rich flavor.

What is the purpose of toasting the bread?
