Common Mistakes to Avoid

Making French Onion Soup Mac & Cheese can be simple, but a few common mistakes can ruin its creamy goodness. Here are some pitfalls to watch out for:

• Overcooking the Pasta: If you cook the macaroni too long, it will become mushy in the final bake. Aim for al dente pasta to maintain texture.

• Skipping Caramelization: Rushing the caramelization of onions can lead to a flat flavor. Take your time and allow them to develop sweetness over 25–30 minutes.

• Not Using Enough Cheese: Cheese is key in this dish! Ensure you use the right amount of Gruyère, cheddar, and mozzarella for a rich, cheesy experience.

• Ignoring Seasoning: Under-seasoned dishes can taste bland. Make sure to season your cheese sauce and pasta adequately with salt and pepper for balanced flavors.

• Inadequate Baking Time: Not baking long enough can result in a saucy consistency. Bake until bubbly and golden on top for that perfect finish.
