Ingredients
  

300g spaghetti or any pasta of your choice

3 large onions, thinly sliced

4 tablespoons olive oil

2 tablespoons unsalted butter

3 cloves garlic, minced

1 teaspoon sugar

Salt and black pepper to taste

1/2 teaspoon red pepper flakes (adjust based on spice preference)

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

Freshly grated Parmesan cheese (for serving)

Chilli oil (for drizzling)

Instructions
 

Cook the Pasta: Begin by filling a large pot with water and bringing it to a boil. Generously season the boiling water with salt. Add the spaghetti or your chosen pasta and cook it according to the package instructions until it's al dente. Before draining, carefully reserve about 1 cup of the pasta cooking water and set it aside.

    Caramelize the Onions: In a large skillet, heat 2 tablespoons of olive oil and 2 tablespoons of butter over medium heat. Once the oil is hot, add the thinly sliced onions along with a pinch of salt. Cook the onions slowly, stirring occasionally, for about 25-30 minutes. You want them to be soft, golden, and beautifully caramelized. If at any point the onions begin to stick to the skillet, add a splash of water to help deglaze and prevent burning.

      Add Garlic and Seasoning: Once the onions are perfectly caramelized, add the minced garlic and sugar to the skillet. Continue cooking for an additional 2-3 minutes, until the garlic becomes fragrant and slightly golden. Season the mixture generously with salt, black pepper, and red pepper flakes to taste, adjusting the heat level according to your preference.

        Combine Pasta and Onions: Add the drained pasta directly to the skillet with the caramelized onions. Toss everything together, gradually adding the reserved pasta water a little at a time until the sauce reaches your desired consistency. Aim for a slightly glossy texture, ensuring it’s not too watery.

          Finish with Olive Oil: Drizzle the remaining 2 tablespoons of olive oil over the pasta. Toss again to fully incorporate the oil and flavor. Taste and adjust seasoning with additional salt and pepper if needed.

            Garnish and Serve: Portion the pasta into serving bowls or plates. Generously sprinkle with freshly chopped parsley and top with a shower of grated Parmesan cheese. To elevate the dish further, drizzle a little chilli oil on top for an extra kick and eye-catching presentation.

              Enjoy: Serve the pasta immediately and relish the delightful combination of sweet caramelized onions paired with a tantalizing spicy hint from the chilli oil!
