How to Make Caramelized Onion Pasta with Chili Oil

Ingredients

  • 2 tablespoons olive oil: For sautéing the onions and garlic.
  • 1 large yellow onion: Thinly sliced. This will be the base for the sweet and savory caramelization.
  • 3 cloves garlic: Minced, for an aromatic base.
  • Salt and pepper: To taste, for seasoning the onions and pasta.
  • 3 tablespoons olive oil: For the base of the chili oil. Extra virgin olive oil works best for its fruity flavor.
  • 1 tablespoon red chili flakes: Adjust this depending on your spice tolerance. You can use less for a mild version or more for a fiery kick.
  • 1 teaspoon paprika: Adds a smoky flavor to complement the chili flakes.
  • 1 small garlic clove: Thinly sliced, to infuse the oil with additional depth.

Directions

  1. Caramelize the Onions: Heat 2 tablespoons of olive oil in a large pan over medium heat. Add the thinly sliced onion and cook, stirring occasionally, for about 15-20 minutes, until the onions are golden brown and caramelized. Add minced garlic for the last few minutes and season with salt and pepper.

  2. Make the Chili Oil: In a small saucepan, heat 3 tablespoons of olive oil over low heat. Add the red chili flakes, sliced garlic, paprika, and soy sauce. Allow this mixture to simmer on low for about 5 minutes to infuse the flavors.

  3. Cook the Pasta: In a large pot, bring water to a boil and add a pinch of salt. Cook the pasta according to package instructions until al dente. Reserve some pasta water, then drain the pasta.

  4. Combine the Pasta and Onions: In the pan with the caramelized onions, add the cooked pasta and a splash of reserved pasta water. Drizzle the chili oil over the pasta and toss everything together until well combined.

  5. Garnish and Serve: Divide the pasta into bowls and sprinkle with grated Parmesan cheese, fresh basil or parsley, and extra chili flakes if desired. Serve hot and enjoy!
