Ingredients
  

300g spaghetti or any pasta of choice

3 large onions, thinly sliced

4 tbsp olive oil

2 tbsp unsalted butter

3 cloves garlic, minced

1 tsp sugar

Salt and black pepper to taste

1/2 tsp red pepper flakes (or more to taste)

1/4 cup fresh parsley, chopped (for garnish)

Freshly grated Parmesan cheese (for serving)

Chilli oil (for drizzling)

Instructions
 

Cook the Pasta: Begin by bringing a large pot of salted water to a boil. Add the pasta and cook according to package instructions until al dente. Reserve 1 cup of pasta cooking water before draining.

    Caramelize the Onions: In a large skillet, heat 2 tablespoons of olive oil and 2 tablespoons of butter over medium heat. Add the sliced onions and a pinch of salt. Stir occasionally, cooking slowly for about 25-30 minutes until the onions are soft, golden, and caramelized. If they start to stick, add a splash of water to deglaze the pan.

      Add Garlic and Season: Once the onions are caramelized, stir in the minced garlic and sugar. Cook for another 2-3 minutes until the garlic is fragrant. Season with salt, black pepper, and red pepper flakes to taste.

        Combine Pasta and Onions: Add the drained pasta to the skillet with the caramelized onions. Toss to combine, adding some reserved pasta water a little at a time until the desired consistency is achieved (the sauce should be slightly glossy but not too watery).

          Finish with Olive Oil: Drizzle the remaining 2 tablespoons of olive oil over the pasta and toss again to incorporate. Adjust seasoning with salt and pepper as necessary.

            Garnish and Serve: Divide the pasta into serving bowls. Top with freshly chopped parsley, and sprinkle with grated Parmesan cheese. Drizzle with chilli oil for an added kick and a stunning presentation.

              Enjoy: Serve immediately and enjoy the harmonious blend of sweet caramelized onions with the spicy kick from the chilli oil!
