Tips for Making the Best Caramelized Onion Pasta with Chilli Oil

Caramelizing onions is an art that takes patience. Here are some tips to ensure success:

  • Low and Slow: Cook the onions on a low flame to prevent them from burning and ensure they caramelize evenly.
  • Use a Non-Stick Pan: It helps in preventing the onions from sticking and burning.
  • Adjust Heat Levels: If you’re new to chilli oil, start with a small amount and add more as you taste.
  • Experiment: Feel free to add other ingredients like mushrooms or spinach for a twist.

Serving Suggestions and Pairings
