Common Mistakes to Avoid

Cooking caramelized onion white beans with rosemary & balsamic can be simple, but there are common mistakes that can affect the dish’s flavor. Here are some to watch out for:

Rushing the onions: Cooking onions too quickly can lead to a burnt taste rather than sweet caramelization. Always cook them on low heat for 30-45 minutes.
Ignoring seasoning: Under-seasoning can make the dish bland. Don’t forget to taste and adjust salt and pepper as needed for the best flavor.
Overcooking the garlic: Garlic burns easily, which can impart a bitter taste. Add it just before the beans, cooking for only a minute.
Not crushing enough beans: Failing to crush some of the beans means missing out on a creamy texture. Use the back of your spoon to break down a portion for a thicker sauce.
Skipping the cheese: Pecorino adds depth and richness. Don’t skip this step; it enhances the overall flavor profile of your dish.
