Begin by boiling water in a large pot. Add your 200 g of pasta and cook according to the package instructions until it's just al dente, usually about 8-10 minutes. Drain and set aside.

In a large pan, warm 3 tablespoons of olive oil over medium heat. Swirl the oil to coat the pan evenly, letting it shimmer but not smoke.

Add the 2 large, thinly sliced onions to the pan. Stir occasionally and cook for about 15-20 minutes until they turn a deep golden brown and are wonderfully sweet.

Once the onions are beautifully caramelized, stir in 2 tablespoons of chili oil along with salt and pepper to taste. Mix well, allowing the flavors to meld for a minute or two.

Gently toss the cooked pasta with the onion mixture, ensuring that every noodle is coated in that rich, savory goodness.

Plate your delicious pasta hot, and if desired, sprinkle with grated Parmesan cheese and fresh herbs for an extra touch of flavor and color.
