Preparation

  • Start by gathering all your ingredients. Slice the onions thinly and prepare the pasta according to the package instructions.

Cooking

  • Bring a large pot of salted water to a boil. Add the pasta and cook until al dente, then drain and set aside, reserving some pasta water.
  • In a large pan, heat 3 tablespoons of olive oil over medium heat. Add the sliced onions and season with salt. Cook until soft and golden brown, about 15-20 minutes.
  • As the onions caramelize, adjust the heat to avoid burning and allow them to develop a rich color without bitterness.
  • Once the onions are caramelized, stir in 2 tablespoons of chili oil and mix well.
  • Season the mixture with salt and freshly cracked pepper, and adjust to taste.
  • Add the cooked pasta to the pan, toss to coat well with the onion and chili oil mixture. If too dry, add a splash of reserved pasta water.
  • Transfer to serving plates and top with grated Parmesan cheese and fresh herbs if desired.

Serving

  • Serve immediately while hot, enjoying the harmonious blend of sweet and spicy flavors.
