FAQs
Can I make this dip ahead of time?

How do I prevent the onions from burning while caramelizing?
Cook the onions over medium or medium-low heat and stir frequently to ensure even cooking.
Can I use pre-shredded cheese?

Can I use a different type of onion?
Yellow onions are ideal, but white or sweet onions also work well. Avoid red onions as they may alter the flavor.
What’s the best way to get the dip golden on top?
If the dip isn’t golden after baking, broil it for 1–2 minutes to achieve a bubbly, browned top.
Can I double the recipe?
Yes, simply use a larger baking dish and adjust the baking time as needed.
What makes Gruyere the best choice for this dip?
Gruyere has a nutty, rich flavor and melts beautifully, making it perfect for warm dips.
