Common Mistakes to Avoid

When preparing Caramelized Onion Pasta with Chilli Oil, it’s easy to make a few common mistakes. Here are some tips to ensure your dish turns out perfectly.

Overcooking the Onions: Cooking onions too quickly can lead to burnt bits instead of caramelization. Always cook them on low heat for a longer time to achieve that sweet, deep flavor.
Skipping Salt in the Pasta Water: Not salting your pasta water can result in bland pasta. Make sure to add enough salt to enhance the overall flavor of the dish.
Using Low-Quality Olive Oil: A good quality olive oil is essential for making chili oil and sautéing onions. Invest in a decent bottle for the best results.
Ignoring the Spice Level: Underestimating chili flakes can make your dish less flavorful. Start with a smaller amount and gradually increase it according to your taste preference.
Not Stirring the Onions: If you don’t stir your onions occasionally, they may cook unevenly or stick to the pan. Keep an eye on them and give them a good stir every few minutes.
Forgetting Fresh Herbs: Fresh parsley can enhance the flavor and presentation of your pasta. Don’t skip this optional garnish—it adds freshness!
