Ingredients
  

Main Ingredients
  • 4 large yellow onions thinly sliced
  • 3 tbsp butter
  • 2 tbsp olive oil
  • 1 tsp salt
  • 0.5 tsp black pepper
  • 2 tbsp brown sugar
  • 0.25 cup dry white wine optional
  • 4 cups beef broth
  • 12 oz wide egg noodles
  • 1.5 cups shredded Gruyere cheese
  • 0.25 cup fresh thyme leaves
  • 2 tbsp Worcestershire sauce
  • 1 tbsp fresh lemon juice

Equipment

  • Large Dutch oven or heavy pot
  • Wooden spoon
  • Sharp knife
  • Cutting board

Method
 

  1. Heat butter and olive oil in a large, heavy-bottomed pot or Dutch oven over medium heat until butter is melted and foaming.
  2. Add sliced onions, salt, and pepper to the pot, stirring to coat onions evenly with the butter and oil mixture.
  3. Cook onions slowly, stirring occasionally, for 15-20 minutes until they become deeply caramelized and golden brown.
  4. Sprinkle brown sugar over the caramelized onions and cook for an additional 2-3 minutes until sugar dissolves and onions become glossy.
  5. Pour in white wine (if using) and scrape up any browned bits from the bottom of the pot, cooking until wine reduces by half.
  6. Add beef broth and Worcestershire sauce, bringing the mixture to a gentle boil over medium-high heat.
  7. Add egg noodles to the boiling broth, stirring gently to prevent sticking, and cook according to package directions until al dente.
  8. Reduce heat to low and gradually stir in shredded Gruyere cheese until melted and creamy throughout the pasta.
  9. Add fresh thyme leaves and lemon juice, stirring gently to combine all ingredients evenly.
  10. Taste and adjust seasoning with additional salt and pepper if needed before serving immediately while hot.

Notes

For best results, don't rush the onion caramelization process. The deeper the color, the richer the flavor. Vegetable broth can be substituted for a vegetarian version. Store leftovers in refrigerator for up to 3 days.
