Ingredients
  

12 oz (340 g) spaghetti or fettuccine

3 large onions, thinly sliced

4 cloves garlic, minced

1/4 cup (60 ml) extra virgin olive oil

1/2 cup (120 ml) chicken or vegetable broth

1/4 cup (60 ml) balsamic vinegar

1 tsp sugar (optional, to enhance caramelization)

Salt, to taste

Freshly cracked black pepper, to taste

1/2 cup (50 g) grated Parmesan cheese (optional)

1-2 tsp chilli oil (adjust to taste)

Fresh parsley, chopped, for garnish

Zest of 1 lemon (optional)

Instructions
 

Cook the Pasta: Begin by boiling a large pot of salted water. Cook the spaghetti or fettuccine according to package instructions until al dente. Reserve about 1 cup of pasta water, then drain and set aside.

    Caramelize the Onions: In a large skillet, heat the olive oil over medium heat. Add the sliced onions, a pinch of salt, and the optional sugar. Stir frequently, cooking for about 20-25 minutes or until the onions are deeply golden and caramelized. If they start to stick, add a splash of broth or water.

      Add Garlic: Once the onions are caramelized, lower the heat to medium-low and add the minced garlic. Sauté for about 1-2 minutes until fragrant, being careful not to burn the garlic.

        Deglaze the Pan: Pour in the balsamic vinegar and scrape up any tasty bits stuck to the bottom of the skillet. Allow it to simmer for 2-3 minutes until slightly thickened.

          Combine with Broth: Add the chicken or vegetable broth to the caramelized onion mixture. Stir well and let it simmer for another 2-3 minutes to combine the flavors and thicken slightly.

            Mix Pasta and Sauce: Add the cooked pasta to the skillet, tossing to combine. If the mixture seems too dry, gradually add reserved pasta water until you reach the desired consistency. Season with salt and pepper to taste.

              Finish with Chilli Oil: Drizzle the chilli oil over the pasta, tossing gently to incorporate and adjust to your heat preference.

                Serve: Plate the pasta and top with freshly grated Parmesan cheese (if using), chopped parsley, and lemon zest for a burst of freshness.

                  Enjoy: Enjoy your delectable Caramelized Onion Pasta with Chilli Oil while hot, savoring the rich flavors and the perfect kick from the chilli oil!
