Method
 

Step-by-Step Instructions
  1. In a large skillet, melt 4 tablespoons of butter over low heat. Add 4 sliced yellow onions and cook for 30–40 minutes until deep golden brown.
  2. Once onions are caramelized, sprinkle 2 tablespoons of flour and stir for 1–2 minutes. Gradually whisk in 4 cups of beef broth and 1 cup of heavy cream, and cook until thickened.
  3. In a pot, boil salted water and cook 12 oz elbow macaroni for about 7–9 minutes until al dente. Drain, reserving ½ cup pasta water.
  4. Add drained macaroni to the cheese sauce, stirring gently. If too thick, mix in reserved pasta water to achieve desired consistency.
  5. Preheat oven to broil. Transfer mac and cheese into an oven-safe dish, top with extra cheese, and broil for 3–5 minutes until golden.
  6. Garnish with chopped herbs before serving. Pairs well with a salad or roasted vegetables.
