Step-by-Step Instructions
  1. In a large skillet over medium-low heat, melt butter. Add onions and cook gently, stirring occasionally, for 30-40 minutes until caramelized.

  4. Fold macaroni into cheese sauce, adding reserved pasta water gradually if needed for desired consistency.

  6. Remove from oven, cool slightly, and garnish with parsley or chives before serving.
