Ingredients

Scale

Main Ingredients:

  • 300 grams (10.5 ounces) pasta of your choice
  • 2 large onions, thinly sliced
  • 1 clove garlic, minced

Seasoning and Flavor Enhancers:

  • 3 tablespoons olive oil
  • 1 tablespoon brown sugar
  • 1 tablespoon balsamic vinegar
  • 1/4 teaspoon chili flakes
  • 3 tablespoons chili oil
  • Salt to taste
  • Freshly ground black pepper to taste

Garnish:

  • Fresh parsley
  • Grated Parmesan cheese (optional)

Instructions

  1. Boil pasta in salted water according to package directions until al dente, then drain while preserving 1/2 cup of starchy cooking liquid.
  2. Place a spacious skillet over medium-low heat, allowing olive oil to warm gently before introducing thinly sliced onions.
  3. Slowly caramelize onions for 15-20 minutes, stirring periodically to ensure even browning and prevent burning.
  4. Incorporate brown sugar and balsamic vinegar, allowing the mixture to develop rich, complex flavors for an additional 3-5 minutes.
  5. Introduce minced garlic and chili flakes, sautéing briefly to release their aromatic essence and enhance the sauce’s depth.
  6. Drizzle chili oil into the caramelized onion mixture, then splash in reserved pasta water to create a silky, cohesive sauce.
  7. Fold cooked pasta into the sauce, ensuring each strand is luxuriously coated with the caramelized onion mixture.
  8. Season with salt and freshly ground black pepper to balance the sweet and spicy notes.
  9. Transfer to serving plates, garnishing with freshly chopped parsley and optional grated Parmesan cheese for an extra layer of indulgence.

Notes

  • Slice onions uniformly to ensure even caramelization and prevent burning during cooking.
  • Use low-medium heat when caramelizing onions to develop deep, rich flavors without scorching.
  • Adjust chili oil quantity based on personal spice tolerance for a customized heat level.
  • Consider using vegan Parmesan or nutritional yeast for a dairy-free version of the dish.
