Ingredients
  

  • 12 oz pasta
  • 3 large yellow onions thinly sliced
  • 2 tbsp unsalted butter
  • 1 tbsp olive oil
  • 3 cloves garlic minced
  • 1 tsp fresh thyme
  • 2 cups beef broth
  • 1 cup heavy cream
  • 1 cup Gruyère cheese freshly grated
  • ½ cup Parmesan cheese freshly grated
  • 1 tsp salt
  • ½ tsp freshly ground black pepper
  • 2 tbsp fresh parsley chopped
  • ¼ cup reserved pasta water as needed

Instructions
 

  • Thinly slice the yellow onions. Keeping the slices similar in thickness helps them cook evenly.
  • Heat the butter and olive oil in a large skillet over medium-low heat. Add the onions and a pinch of salt. Cook slowly, stirring occasionally, until the onions are very soft and deeply golden, about 20–25 minutes.
  • Add the minced garlic and fresh thyme to the caramelized onions. Cook for about 1 minute, until fragrant.
  • Pour in the beef broth and scrape the bottom of the skillet with a wooden spoon to release the flavorful browned bits. Stir in the heavy cream and bring the sauce to a gentle simmer.
  • Meanwhile, cook the pasta in salted water according to the package directions until al dente. Reserve a little pasta water, then drain.
  • Add the cooked pasta to the creamy onion sauce. Toss well until the pasta is completely coated. Add a splash of reserved pasta water if the sauce is too thick.
  • Reduce the heat to low. Add the Gruyère and Parmesan cheese gradually, stirring until the cheeses melt and the sauce becomes smooth and creamy.
  • Season with freshly ground black pepper and additional salt if needed. Garnish with fresh parsley and extra grated Parmesan or Gruyère before serving.

Notes

 
  • Caramelize the onions slowly: Don’t rush this step. Slowly cooked onions develop a deep golden color and rich, naturally sweet flavor that gives the pasta its signature French onion taste.
  • Use freshly grated cheese: Freshly grated Gruyère and Parmesan melt more smoothly into the sauce and create a richer, creamier texture.
  • Save some pasta water: Keep a little pasta water before draining. Its natural starch helps loosen the sauce and gives the finished pasta a silky consistency.
  • Keep the heat low when adding cheese: Add the cheese over low heat and stir gently until melted. This helps prevent the creamy sauce from becoming greasy or separating.
  • Serve it while hot: French Onion Pasta is best enjoyed immediately while the sauce is creamy and the cheese is perfectly melted. Finish with fresh parsley and extra Parmesan for the best flavor.
