Method
 

Step 1. Caramelize the Onions
  1. In a large skillet, heat 1 tbsp olive oil and 2 tbsp butter over medium-low heat.
  2. Add the sliced onions and a pinch of salt.
  3. Cook slowly, stirring occasionally, for 25–30 minutes until deeply golden and caramelized.
  4. In the last 2 minutes, add minced garlic and ½ tsp dried thyme.
  5. Optional: Deglaze the pan with ½ cup white wine, scraping up any browned bits. Let it simmer until mostly evaporated.
Step 2. Cook the Pasta
  1. While onions cook, bring a large pot of salted water to a boil.
  2. Cook the pasta until al dente. Reserve ½ cup of pasta water, then drain and set aside.
Step 3. Make the Sauce
  1. To the caramelized onions, add 1½ cups beef or veggie broth and simmer for 2–3 minutes.
  2. Add ½ cup heavy cream and stir until combined.
  3. Mix in 1½ cups shredded Gruyère and ¼ cup Parmesan, stirring until smooth and melty.
  4. Season with salt and pepper to taste.
Step 4. Combine Everything
  1. Add the drained pasta into the skillet with the sauce.
  2. Toss to coat evenly, adding a splash of reserved pasta water if needed to loosen the sauce.
  3. Let everything simmer together for 1–2 minutes so the pasta absorbs the flavor.
Step 5. Garnish and Serve
  1. Plate warm, topped with more cheese and chopped parsley if desired.
  2. Optional: Transfer to an oven-safe dish, sprinkle with more cheese, and broil until bubbly and golden on top.
