This French Onion Soup Mac & Cheese is a comforting fusion of two beloved classics. Sweet caramelized onions are slowly cooked to golden perfection and blended into a creamy, cheesy béchamel base. Pasta is tossed in the sauce and then baked with slices of toasted baguette and extra cheese until bubbling and golden brown. With layers of savory depth and melty richness, it’s the perfect dish for cozy nights or holiday indulgence.

Tips & Tricks (5)
- Caramelization Mastery 🧅Slowly caramelize onions over low heat for 45-60 minutes, stirring occasionally to develop deep, rich flavor without burning.
- Cheese Blend Precision 🧀Grate your own cheese blend fresh and bring to room temperature before mixing to ensure a smoother, more even melt and creamier sauce.
- Baguette Crouton Technique 🥖Brush baguette slices with garlic-infused olive oil and toast until golden brown before topping the mac & cheese for maximum flavor and crunch.
- Béchamel Balance 🥛Whisk flour and butter slowly to create a smooth roux, then gradually add cold milk to prevent lumps and ensure a silky sauce.
- Depth of Flavor Layer 🌿Deglaze the caramelized onion pan with a splash of sherry or white wine to capture all the concentrated flavor before adding to the mac & cheese.
