Description

This French Onion Pasta is a comforting fusion dish combining the rich, caramelized flavors of classic French onion soup with hearty pasta. Slow-cooked onions create a deep, sweet base, complemented by garlic, fresh thyme, white wine, and Dijon mustard. The pasta simmers in a savory beef broth until perfectly al dente, then is enriched with creamy smoked gouda and parmesan for a luscious, cheesy finish. Garnished with fresh thyme, this dish is an indulgent and flavorful main course perfect for a cozy meal.


Ingredients

Base

  • 3 tbsp olive oil
  • 3 yellow onions, thinly sliced
  • 3 garlic cloves, minced
  • 1 tbsp fresh thyme, plus more for garnish
  • 1 tsp sea salt
  • 1/2 tsp ground black pepper

Liquids and Flavorings

  • 1/2 cup dry white wine
  • 1 tbsp Dijon mustard
  • 4 cups beef broth
  • 1/2 cup heavy cream or full-fat coconut milk

Pasta and Cheese

  • 12 oz short pasta (gluten-free malfada recommended)
  • 1/2 cup shredded smoked gouda
  • 1/2 cup shredded parmesan, plus extra for garnish


Instructions

  1. Caramelize Onions: Heat olive oil in a large skillet over medium heat. Add thinly sliced onions and cook, stirring frequently, until deeply browned and caramelized, about 30 to 40 minutes, developing rich sweetness without burning.
  2. Add Aromatics and Deglaze: Stir in minced garlic, fresh thyme, sea salt, and black pepper, cooking for 2 minutes until fragrant. Pour in white wine and Dijon mustard, scraping the pan bottom with a wooden spoon to deglaze and lift all browned bits for about 2 minutes.
  3. Simmer Pasta in Broth: Add the short pasta and beef broth to the pan. Increase heat to medium-high and simmer uncovered, stirring occasionally to prevent sticking, until most broth is absorbed and pasta is al dente, about 10-15 minutes. Add a splash of water if liquid evaporates too quickly.
  4. Melt Cheeses and Finish: Stir in heavy cream, smoked gouda, and parmesan cheese. Continue to simmer and stir for 1-2 minutes until cheeses are fully melted and integrated into a creamy sauce.
  5. Adjust Seasoning and Serve: Taste the pasta and adjust seasoning if needed. Serve warm, garnished with additional fresh thyme and a sprinkle of parmesan cheese for extra flavor and presentation.

Notes

  • Caramelizing onions properly is key; don’t rush as it takes 30-40 minutes to develop deep flavor without bitterness.
  • If onions or pasta start sticking, deglaze the pan with a splash of water, wine, or broth to loosen the fond.
  • Use a wide skillet or cast-iron pan to allow even cooking and efficient steam release during caramelization.
