Method
 

Step 1:
  1. Bring a large pot of salted water to a boil. Cook the pasta according to package instructions until al dente. Reserve ½ cup of pasta water, then drain and set aside.
Step 2:
  1. Heat the olive oil and butter in a large skillet over medium heat. Add the sliced onions and cook, stirring occasionally, for 20–25 minutes until deeply golden and caramelized.
Step 3:
  1. Add the minced garlic, dried thyme, black pepper, and kosher salt to the onions. Stir and cook for 30 seconds until fragrant.
Step 4:
  1. Pour in the broth and scrape the bottom of the pan to release any browned bits. Let the mixture simmer for 3–5 minutes until slightly reduced.
Step 5:
  1. Stir in the heavy cream and bring to a gentle simmer. Cook for 2–3 minutes until the sauce thickens slightly.
Step 6:
  1. Add the cooked pasta to the skillet and toss to coat evenly. Add reserved pasta water a little at a time if needed to loosen the sauce.
Step 7:
  1. Sprinkle in the grated cheese and stir until melted and creamy.
Step 8:
