These Carbs Don't Count
June 4, 2025
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.
